P2P Sender Interface +Node's rpcchainvm implements `p2p.Sender` (from `github.com/luxfi/p2p`) for cross-chain messaging. +The `sender` package is a gRPC implementation of `p2p.Sender`. + +### 2. Chain Tracking +Nodes don't automatically track chains. Use: +```bash +--track-chains= +``` +Or create config: `~/.lux/runs/.../node*/chainConfigs/.json` + +### 3. Genesis blobSchedule +Mainnet genesis requires Cancun fork config: +```json +"blobSchedule": { + "cancun": { + "max": 6, + "target": 3, + "baseFeeUpdateFraction": 3338477 + } +} +``` + +### 4. Network Snapshots +CLI creates new directories on restart. Use snapshots: +```bash +lux network save --snapshot-name +lux network start --snapshot-name +``` + +### 5. EIP-3860 Historic Blocks +For importing pre-merge blocks, Shanghai must be active based on `ShanghaiTime`, not merge status. + +### 6. Genesis Hash Mismatch on Restart +**Problem**: "db contains invalid genesis hash" error when restarting nodes. + +**Cause**: Genesis bytes are rebuilt from JSON config on each start. Due to non-deterministic JSON serialization (map iteration order), the rebuilt bytes differ from the original, causing hash mismatch. + +**Solution**: Genesis bytes are now cached to `genesis.bytes` file in the node's data directory. On subsequent restarts, the cached bytes are used directly. This happens automatically when using `--genesis-file`. + +### 7. VM Config Format Mismatch +**Problem**: "failed to parse config: unknown codec version" for T-Chain (ThresholdVM) or Z-Chain (ZKVM) in dev mode. + +**Cause**: Two issues: +1. Genesis builder passes JSON config (`{"version":1,"message":"..."}`) to VMs that expect binary codec format +2. Dev mode's automining config injection converts all chain configs to JSON, breaking binary-codec VMs + +**Solution**: +- `genesis/builder/builder.go`: T-Chain and Z-Chain use `[]byte(config.TChainGenesis)` (empty bytes for defaults) instead of `getGenesis()` which returns JSON +- `chains/manager.go`: `injectAutominingConfig` only injects for `EVMID`, skipping binary-codec VMs + +**Alternative**: Use `--genesis-raw-bytes` flag to pass base64-encoded pre-built genesis bytes directly. + +## File Locations + +| Item | Path | +|------|------| +| luxd binary | `~/.lux/bin/luxd/luxdv*/luxd` | +| VM plugins | `~/.lux/plugins/` | +| Network runs | `~/.lux/runs/local_network/network_*` | +| Snapshots | `~/.lux/snapshots/` | +| Chain configs | `~/.lux/chain-configs//` | + +## Build Order + +1.

P-Chain Block Sync (isMissingContextError "not found") +**Problem**: New validator node stays at P-chain height 0 even after connecting to testnet peers. Blocks received via Put/PushQuery are silently discarded. + +**Root Cause**: `HandleIncomingBlock` returns `"not found"` when the block's parent isn't in the local state. `isMissingContextError` didn't recognize `"not found"` as a missing-context condition, so `requestContext` (GetAncestors) was never called. + +**Fix** in `chains/manager.go`, `isMissingContextError`: +```go +// Added "not found" pattern: +strings.Contains(errStr, "not found") // parent block not in local state +``` + +**Effect**: Now when a block arrives whose parent is unknown, the handler sends `GetAncestors` to the peer, receives the full ancestor chain, and processes blocks in order, advancing the P-chain height. + +**Note**: The network layer (`network.go:sequencerID`) already correctly maps native chain IDs (P, C, X, etc.) to `PrimaryNetworkID` for validator set lookups — no separate gossip fix needed. + +### Known CGO Stubs +When CGO disabled, these use CPU fallbacks: +- `consensus/quasar/gpu_ntt_nocgo.go` +- `vms/thresholdvm/fhe/gpu_fhe_nocgo.go` +- `vms/zkvm/accel/accel_mlx.go` + +### 8.

Root "/" Endpoint Handler +**Feature**: The node's root endpoint ("/") provides EVM compatibility and node information. + +**Behavior**: +- **GET /**: Returns JSON node information (nodeId, networkId, version, chains, endpoints) +- **POST /**: Proxies JSON-RPC requests directly to C-chain `/ext/bc/C/rpc` +- **OPTIONS /**: Returns CORS preflight headers + +**Files Modified**: `server/http/router.go`, `server/http/server.go` + +**Types**: +```go +type RootInfo struct { + NodeID string `json:"nodeId,omitempty"` + NetworkID uint32 `json:"networkId,omitempty"` + Version string `json:"version,omitempty"` + Ready bool `json:"ready"` + Chains struct { C, P, X string } `json:"chains"` + Endpoints struct { RPC, Websocket, Info, Health string } `json:"endpoints"` +} + +type RootInfoProvider interface { + GetRootInfo() RootInfo +} +``` + +**Usage**: +```bash +# Get node info +curl http://localhost:9650/ + +# Send EVM JSON-RPC directly to root (proxied to C-chain) +curl -X POST -H "Content-Type: application/json" \ + -d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}' \ + http://localhost:9650/ +``` + +**Implementation Notes**: +- The Server interface exposes `SetRootInfoProvider(provider)` to configure node info +- When no provider is set, returns default endpoint paths +- POST errors return proper JSON-RPC error format if C-chain unavailable + +### 10. BLS Key Not Loaded into Validators Manager +**Problem**: Health check shows "validator doesn't have a BLS key" despite BLS keys being correctly configured in genesis. + +**Cause**: The `initValidatorSets()` function in `/vms/platformvm/state/state.go` was skipping validator population when `NumNets() != 0`. This happened because: +1. Network layer might pre-populate validators (without BLS keys) before state initialization +2. When `initValidatorSets()` runs, it sees validators exist and skips adding them with proper BLS keys +3. The health check queries `n.vdrs.GetValidator()` which returns validator with nil PublicKey + +**Solution**: Modified `initValidatorSets()` to always add validators (not skip when `NumNets() != 0`). The `AddStaker` method replaces existing entries, so validators get updated with proper BLS keys. + +**File Modified**: `vms/platformvm/state/state.go` (line ~2144) + +**Before**: +```go +if

However, if the +flag is set, the specified folder must exist, or Lux Node will exit with an +error. This flag is ignored if `--chain-config-content` is specified. + +:::note +Please replace `chain-config-dir` and `blockchainID` with their actual values. +::: + +Network upgrades are passed in from the location: +`chain-config-dir`/`blockchainID`/`upgrade.*`. +Upgrade files are typically json encoded and therefore named `upgrade.json`. +However, the format of the file is VM dependent. +After a blockchain has activated a network upgrade, the same upgrade +configuration must always be passed in to ensure that the network upgrades +activate at the correct time. + +The chain configs are passed in from the location +`chain-config-dir`/`blockchainID`/`config.*`. +Upgrade files are typically json encoded and therefore named `upgrade.json`. +However, the format of the file is VM dependent. +This configuration is used by the VM to handle optional configuration flags such +as enabling/disabling APIs, updating log level, etc. +The chain configuration is intended to provide optional configuration parameters +and the VM will use default values if nothing is passed in. + +Full reference for all configuration options for some standard chains can be +found in a separate [chain config flags](https://docs.lux.network/docs/nodes/chain-configs) document. + +Full reference for Chain EVM upgrade configuration can be found in a separate +[Customize a Chain](https://docs.lux.network/docs/lux-l1s/upgrade/customize-lux-l1) document. + +#### `--chain-config-content` (string) + +As an alternative to `--chain-config-dir`, chains custom configurations can be +loaded altogether from command line via `--chain-config-content` flag.

Chain +aliases are added after adding primary network aliases and before any changes to +the aliases via the admin API. This means that the first alias included for a +Blockchain on a Chain will be treated as the `"Primary Alias"` instead of the +full blockchainID. The Primary Alias is used in all metrics and logs. + +#### `--chain-aliases-file-content` (string) + +As an alternative to `--chain-aliases-file`, it allows specifying base64 encoded +aliases for Blockchains. + +#### `--chain-data-dir` (string) + +Chain specific data directory. Defaults to `$HOME/.node/chainData`. + +## Config File + +#### `--config-file` (string) + +Path to a JSON file that specifies this node's configuration.

human-readable representation of the transaction. + +To get an X-Chain transaction by its index (the order it was accepted in), use Index API method [index.getlastaccepted](#indexgetlastaccepted). +

However, there is no reliance on any certificate authorities. The `network` package identifies peers by the public key in the leaf certificate. + +## Peers + +Peers are defined as members of the network that communicate with one another to participate in the Lux protocol. + +Peers communicate by enqueuing messages between one another. Each peer on either side of the connection asynchronously reads and writes messages to and from the remote peer. Messages include both application-level messages used to support the Lux protocol, as well as networking-level messages used to implement the peer-to-peer communication layer. + +```mermaid +sequenceDiagram + actor Morty + actor Rick + loop + Morty->>Rick: Write outbound messages + Rick->>Morty: Read incoming messages + end + loop + Rick->>Morty: Write outbound messages + Morty->>Rick: Read incoming messages + end +``` + +### Message Handling + +All messages are prefixed with their length. Reading a message first reads the 4-byte message length from the connection. The rate-limiting logic then waits until there is sufficient capacity to read these bytes from the connection. + +A peer will then read the full message and attempt to parse it into either a networking message or an application message. If the message is malformed the connection is not dropped. The peer will simply continue to the next sent message. + +### Peer Handshake + +Upon connection to a new peer, a handshake is performed between the node attempting to establish the outbound connection to the peer and the peer receiving the inbound connection. + +When attempting to establish the connection, the first message that the node sends is a `Handshake` message describing the configuration of the node. If the `Handshake` message is successfully received and the peer decides that it will allow a connection with this node, it replies with a `PeerList` message that contains metadata about other peers that allows a node to connect to them. See [PeerList Gossip](#peerlist-gossip). + +As an example, nodes that are attempting to connect with an incompatible version of Lux Node or a significantly skewed local clock are rejected. + +```mermaid +sequenceDiagram + actor Morty + actor Rick + Note over Morty,Rick: Connection Created + par + Morty->>Rick: Lux Node v1.0.0 + and + Rick->>Morty: Lux Node v1.11.4 + end + Note right of Rick: v1.0.0 is incompatible with v1.11.4. + Note left of Morty: v1.11.4 could be compatible with v1.0.0! + par + Rick-->>Morty: Disconnect + and + Morty-XRick: Peerlist + end + Note over Morty,Rick: Handshake Failed +``` + +Nodes that mutually desire the connection will both respond with `PeerList` messages and complete the handshake. + +```mermaid +sequenceDiagram + actor Morty + actor Rick + Note over Morty,Rick: Connection Created + par + Morty->>Rick: Lux Node v1.11.0 + and + Rick->>Morty: Lux Node v1.11.4 + end + Note right of Rick: v1.11.0 is compatible with v1.11.4! + Note left of Morty: v1.11.4 could be compatible with v1.11.0! + par + Rick->>Morty: Peerlist + and + Morty->>Rick: Peerlist + end + Note over Morty,Rick: Handshake Complete +``` + +### Ping-Pong Messages + +Peers periodically send `Ping` messages containing perceived uptime information. This information can be used to monitor how the node is considered to be performing by the network. It is expected for a node to reply to a `Ping` message with a `Pong` message. + +```mermaid +sequenceDiagram + actor Morty + actor Rick + Note left of Morty: Send Ping + Morty->>Rick: I think your uptime is 95% + Note right of Rick: Send Pong + Rick->>Morty: ACK +``` + +## Peer Discovery + +When starting a Lux node, a node needs to be able to initiate some process that eventually allows itself to become a participating member of the network. In traditional web2 systems, it's common to use a web service by hitting the service's DNS and being routed to an available server behind a load balancer. In decentralized p2p systems, however, connecting to a node is more complex as no single entity owns the network. [Lux consensus](https://docs.lux.network/docs/quick-start/lux-consensus) requires a node to repeatedly sample peers in the network, so each node needs some way of discovering and connecting to every other peer to participate in the protocol. + +### Inbound Connections + +It is expected for Lux nodes to allow inbound connections. If a validator does not allow inbound connections, its observed uptime may be reduced. + +### Outbound Connections + +Lux nodes that have identified the `IP:Port` pair of a node they want to connect to will initiate outbound connections to this `IP:Port` pair. If the connection is not able to complete the [Peer Handshake](#peer-handshake), the connection will be re-attempted with an [Exponential Backoff](https://en.wikipedia.org/wiki/Exponential_backoff). + +A node should initiate outbound connections to an `IP:Port` pair that is believed to belong to another node that is not connected and meets at least one of the following conditions: +- The peer is in the initial bootstrapper set. +- The peer is in the default bootstrapper set. +- The peer is a Primary Network validator. +- The peer is a validator of a tracked Net. +- The peer is a validator of a Net and the local node is a Primary Network validator. + +#### IP Authentication + +To ensure that outbound connections are being made to the correct `IP:Port` pair of a node, all `IP:Port` pairs sent by the network are signed by the node that is claiming ownership of the pair. To prevent replays of these messages, the signature is over the `Timestamp` in addition to the `IP:Port` pair. + +The `Timestamp` guarantees that nodes provided an `IP:Port` pair can track the most up-to-date `IP:Port` pair of a peer. + +### Bootstrapping + +In Lux, nodes connect to an initial set (this is user-configurable) of bootstrap nodes. + +### PeerList Gossip + +Once connected to an initial set of peers, a node can use these connections to discover additional peers. + +Peers are discovered by receiving [`PeerList`](#peerlist) messages during the [Peer Handshake](#peer-handshake). These messages quickly provide a node with knowledge of peers in the network. However, they offer no guarantee that the node will connect to and maintain connections with every peer in the network. + +To provide an eventual guarantee that all peers learn of one another, nodes periodically send a [`GetPeerList`](#getpeerlist) message to a randomly selected Primary Network validator with the node's current [Bloom Filter](#bloom-filter) and `Salt`. + +#### Gossipable Peers + +The peers that a node may include into a [`GetPeerList`](#getpeerlist) message are considered `gossipable`. + + +#### Trackable Peers + +The peers that a node would attempt to connect to if included in a [`PeerList`](#peerlist) message are considered `trackable`. + +#### Bloom Filter + +A [Bloom Filter](https://en.wikipedia.org/wiki/Bloom_filter) is used to track which nodes are known. + +The parameterization of the Bloom Filter is based on the number of desired peers. + +Entries in the Bloom Filter are determined by a locally calculated [`Salt`](https://en.wikipedia.org/wiki/Salt_(cryptography)) along with the `NodeID` and `Timestamp` of the most recently known `IP:Port`. The `Salt` is added to prevent griefing attacks where malicious nodes intentionally generate hash collisions with other virtuous nodes to reduce their connectivity. + +The Bloom Filter is reconstructed if there are more entries than expected to avoid increasing the false positive probability. It is also reconstructed periodically. When reconstructing the Bloom Filter, a new `Salt` is generated. + +To prevent a malicious node from arbitrarily filling this Bloom Filter, only `2` entries are added to the Bloom Filter per node. If a node's `IP:Port` pair changes once, it will immediately be added to the Bloom Filter. If a node's `IP:Port` pair changes more than once, it will only be added to the Bloom Filter after the Bloom Filter is reconstructed. + +#### GetPeerList + +A `GetPeerList` message contains the Bloom Filter of the currently known peers along with the `Salt` that was used to add entries to the Bloom Filter. Upon receipt of a `GetPeerList` message, a node is expected to respond with a `PeerList` message. + +#### PeerList + +`PeerList` messages are expected to contain `IP:Port` pairs that satisfy all of the following constraints: +- The Bloom Filter sent when requesting the `PeerList` message does not contain the node claiming the `IP:Port` pair. +- The node claiming the `IP:Port` pair is currently connected. +- The node claiming the `IP:Port` pair is either in the default bootstrapper set, is a current Primary Network validator, is a validator of a tracked Net, or is a validator of a Net and the peer is a Primary Network validator. + +#### Avoiding Persistent Network Traffic + +To avoid persistent network traffic, it must eventually hold that the set of [`gossipable peers`](#gossipable-peers) is a subset of the [`trackable peers`](#trackable-peers) for all nodes in the network. + +For example, say there are 3 nodes: `Rick`, `Morty`, and `Summer`. + +First we consider the case that `Rick` and `Morty` consider `Summer` [`gossipable`](#gossipable-peers) and [`trackable`](#trackable-peers), respectively. +```mermaid +sequenceDiagram + actor Morty + actor Rick + Note left of Morty: Not currently tracking Summer + Morty->>Rick: GetPeerList + Note right of Rick: Summer isn't in the bloom filter + Rick->>Morty: PeerList - Contains Summer + Note left of Morty: Track Summer and add to bloom filter + Morty->>Rick: GetPeerList + Note right of Rick: Summer is in the bloom filter + Rick->>Morty: PeerList - Empty +``` +This case is ideal, as `Rick` only notifies `Morty` about `Summer` once, and never uses bandwidth for their connection again. + +Now we consider the case that `Rick` considers `Summer` [`gossipable`](#gossipable-peers), but `Morty` does not consider `Summer` [`trackable`](#trackable-peers). +```mermaid +sequenceDiagram + actor Morty + actor Rick + Note left of Morty: Not currently tracking Summer + Morty->>Rick: GetPeerList + Note right of Rick: Summer isn't in the bloom filter + Rick->>Morty: PeerList - Contains Summer + Note left of Morty: Ignore Summer + Morty->>Rick: GetPeerList + Note right of Rick: Summer isn't in the bloom filter + Rick->>Morty: PeerList - Contains Summer +``` +This case is suboptimal, because `Rick` told `Morty` about `Summer` multiple times. If this case were to happen consistently, `Rick` may waste a significant amount of bandwidth trying to teach `Morty` about `Summer`. \ No newline at end of file diff --git a/network/certs_test.go b/network/certs_test.go new file mode 100644 index 000000000..daa7cbd36 --- /dev/null +++ b/network/certs_test.go @@ -0,0 +1,43 @@ +// Copyright (C) 2019-2025, Lux Industries Inc.

It is guaranteed that no locks from the health checker are held during the execution of the health check. + +When the health check worker is stopped, it will finish executing any currently running health checks and then terminate its primary goroutine. After the health check worker is stopped, the health checks will never run again. diff --git a/service/health/checker.go b/service/health/checker.go new file mode 100644 index 000000000..8a435e86a --- /dev/null +++ b/service/health/checker.go @@ -0,0 +1,23 @@ +// Copyright (C) 2019-2025, Lux Industries Inc.

A validator set defines a group of validators and their specified weights in the consensus process. A chain is a validator set working together to achieve consensus on a set of blockchains. Every blockchain is validated by one chain, and one chain can validate many blockchains. + +There is a special chain inherent to the Lux Network called the Primary Network. The Primary Network is validated by every node on the Lux network. All chains' validator sets are required to be a subset of the Primary Network's validator set. That is, if a validator belongs to a chain then it also belongs to the Primary Network. The Primary Network validates three blockchains that are inherent to the Lux Network: the P-Chain, C-Chain, and X-Chain. + +For each blockchain, consensus is driven by the consensus engine. For each chain, the P-Chain, or Platform Chain, defines the validator set and the set of blockchains that are validated by the chain. + +A blockchain consists of two components: a consensus engine and a Virtual Machine (VM). The consensus engine samples validators, handles the responses, and pushes the results of the completed polls into the consensus [code](../consensus/consensus/) to decide which containers to Accept/Reject. The VM encodes the application logic for the blockchain. The VM defines the contents of a block, the rules for determining whether a block is valid, the APIs exposed to users, the state transition that occurs if a given block is accepted, and so on. + +The consensus engine is general and agnostic to the application semantics of the blockchain. There are two consensus engine implementations in Lux Node: Consensusman and Lux. Consensusman provides a consensus engine for linear chains and Lux provides a consensus engine for DAGs. These consensus engine implementations can be re-used for multiple different blockchains in the Lux ecosystem, and each blockchain actually runs its own independent instance of consensus. + +To launch a blockchain on Lux, you just need to write a VM that defines your application; the consensus part is handled by the existing consensus engine implementations. + +This document will go into the details of implementing a ChainVM to run on the Linear consensus engine. To implement a VM for linear, we just need to implement the `ChainVM` interface defined [here.](../consensus/engine/linear/block/vm.go) + +VMs are reusable. Arbitrarily many blockchains can run the same VM. Each blockchain has its own state. In this way, a VM is to a blockchain what a class is to an instance of a class in an object-oriented programming language. + +## Linear VM From the Perspective of the Consensus Engine + +To the consensus engine, the Linear VM is a black box that handles all block building, parsing, and storage and provides a simple block interface for the consensus engine to call as it decides blocks. + +### Linear VM Block Handling + +The Linear VM needs to implement the following functions used by the consensus engine during the consensus process. + +#### Build Block + +Build block allows the VM to propose a new block to be added to consensus. + +The VM can send messages to the consensus engine through a `toEngine` channel that is passed in when the VM is initialized. This channel allows the VM to send the consensus engine a message when it is ready to build a block. For example, if the VM receives some transactions via gossip or from an API, then it will signal that it is ready to build a block by sending a `PendingTxs` message to the consensus engine. The PendingTxs message signals to the consensus engine that it should call `BuildBlock()` so that the block can be added to consensus. + +The major caveat to this is the Linear VMs are wrapped with [Linear++](./proposervm/README.md). Linear++ provides congestion control by using a soft leader, where a leader is designated as the proposer that should create a block at a given time. Linear++ gracefully falls back to increase the number of validators that are allowed to propose a block to handle the case that the leader does not propose a block in a timely manner. + +Since a VM may be ready to build a block before its turn to propose a block according to Linear++, the proposer VM will buffer PendingTxs messages until the ProposerVM agrees that it is time to build a block as well. This means that the consensus engine is not guaranteed to receive the `PendingTxs` message and call `BuildBlock()` in a timely manner. + +When the consensus engine does call `BuildBlock`, the VM should build a block on top of the currently [preferred block](#set-preference). This increases the likelihood that the block will be accepted since if the VM builds on top of a block that is not preferred, then the consensus engine is already leaning towards accepting something else, such that the newly created block will be more likely to get rejected. + +#### Parse Block + +Parse block provides the consensus engine the ability to parse a byte array into the block interface. + +`ParseBlock(bytes []byte)` attempts to parse a byte array into a block, so that it can return the block interface to the consensus engine. ParseBlock can perform syntactic verification to ensure that a block is well formed. For example, if a certain field of a block is invalid such that the block can be immediately determined to not be valid, ParseBlock can immediately return an error so that the consensus engine does not need to do the extra work of verifying it. + +It is required for all historical blocks to be parsable. + +#### GetBlock + +GetBlock fetches blocks that are already known to the VM. If the block has been verified, the VM is required to return that uniquified block when requested until Accept or Reject are called. After a block has been decided, it is no longer necessary to return a uniquified block, and if the block has been rejected the VM is no longer required to store that block or return it at all. + +#### Set Preference + +The VM implements the function `SetPreference(blkID ids.ID)` to allow the consensus engine to notify the VM which block is currently preferred to be accepted. The VM should use this information to set the head of its blockchain. Most importantly, when the consensus engine calls BuildBlock, the VM should be sure to build on top of the block that is the most recently set preference. + +Note: SetPreference will always be called with a block that has no verified children. + +### Implementing the Linear VM Block + +From the perspective of the consensus engine, the state of the VM can be defined as a linear chain starting from the +genesis block through to the last accepted block. + +Following the last accepted block, the consensus engine may have any number of different blocks that are +processing. The configuration of the processing set can be defined as a tree with the last accepted +block as the root. + +In practice, this looks like the following: + +``` + G + | + . + . + . + | + L + | + A + / \ + B C +``` + +In this example, G -> ... -> L is the linear chain of blocks that have already been accepted by the consensus +engine. + +A, with parent block L, has been issued into consensus and is currently in processing. +Blocks B and C, both with parent block A, have also been issued into consensus and are currently in processing +as well. + +We will call this state a possible configuration of the ChainVM from the view of the consensus engine, and +we will try to define clearly the set of possible steps from this configuration to the next, which the ChainVM +must implement correctly. + +Given a configuration of the consensus engine, there are three possible actions the consensus engine may take: + +1. The consensus engine will attempt to verify a block whose parent is either the last accepted block or is currently in consensus. +2. The consensus engine may change its preference (update the block that it currently prefers to accept). +3. The consensus engine may arrive at a decision and call Accept/Reject on a series of blocks. + +If the consensus engine arrives at a decision, then it may have decided one or more blocks and will perform +the following steps: + +1. Call Accept on a block +2. Call Reject on all transitive conflicts +3. Repeat steps 1-2 until there are no more blocks to accept + +Therefore, if the tree of blocks in consensus (with root L, the last accepted block), looks like the following: + +``` + L + / \ + A B + | / \ + C D G + / \ + E F +``` + +If the consensus engine decides A and C simultaneously, the consensus engine would perform the following operations: + +1. Accept(A) +2. Reject(B), Reject(D), Reject(E), Reject(F), and Reject(G) +3. Accept(C) + +To see the actual code where Accept/Reject are performed, look [here.](../consensus/consensus/linear/topological.go) + +### Block Statuses + +A block's status must be one of `Accepted`, `Rejected`, `Processing`. + +A block that is `Accepted` or `Rejected` is considered to be `Decided`. + +#### Processing Blocks + +If a block has status `Processing` we have the byte representation of the block and have parsed it but have not decided it. + +Additionally, blocks with status `Processing` may or may not have had `Verify()` called on them. Therefore, a block with status `Processing` hasn't necessarily been added to consensus. That is, the consensus engine may not be trying to decide the block. Before adding a block to consensus, the consensus engine verifies the block to ensure it's valid. The VM defines what constitutes a valid block for that blockchain. + +For example, when a node receives a block from the network it will call `ParseBlock(blockBytes)` and return a block to the consensus engine. This block has not yet been fully verified and is not in consensus at this point. When the consensus engine has fetched its full ancestry and is ready to issue it to consensus, it will verify all of the block's ancestors, call `Verify()` on this block as well, and if it returns a nil error, then the block will be added to consensus. + +#### Accepted Blocks + +After `Accept` has been called on a block, it must report status `Accepted`. Accepted blocks must still be retrievable by VM method `GetBlock`. + +#### Rejected Blocks + +After `Reject` has been called on a block, it should report its status as rejected. This is not required to be maintained forever. After Reject has been called, it may be convenient to keep it in a caching layer so that its status is easily accessible. For performance reasons, it may be optimal to report the status of a block as rejected until the last accepted block height is >= the rejected block height, since at that point the consensus engine can see its height and immediately see that the block does not need to be processed again. + +### Uniquifying Blocks + +The consensus engine requires that the VM return a unique reference to blocks when they are in consensus. + +To repeat, from the perspective of the VM, a block is in consensus if `Verify()` has been called on it and it returned no error, but the block has not yet been decided. In other words, `Verify()` has successfully returned, but not yet been followed by `Accept()` or `Reject()`. + +When a block is processing, the VM needs to ensure that any function on the VM that gets called and returns a block, returns a reference to that same block that the consensus engine has a reference to. + +After a block has been decided, the consensus engine will not call `Verify()`, `Accept()`, or `Reject()` on the same block again. Since the block will not go through consensus again, it's safe to return a non-unique block if that block has already been decided. + +If a block is processing, but hasn't been verified (i.e. it hasn't been added to consensus) then it is also safe to return a non-unique block. + +Once `Verify()` has been called and returns a non-nil error, the VM must subsequently return a reference to the same block. + +This means that the VM needs to handle uniquification and leads to very specific requirements for how blocks are cached. This is why the [chain](./components/chain/) package was implemented to create a simple helper that helps a VM implement an efficient caching layer while correctly uniquifying blocks. For an example of how it's used, you can look at the [rpcchainvm](./rpcchainvm/). + +## Linear VM APIs + +The VM must also implement `CreateHandlers()` which can return a map of extensions mapped to HTTP handlers that will be added to the node's API server.

+[Background](#lux-chains-and-custom-vms) + +[Introduction](#introduction) + +[Usage](#how-it-works) + +[Running](#running-the-vm) + +[Demo](#cross-chain-transaction-example) + +## Lux Nets and Custom VMs + +Lux is a network composed of multiple networks +that each contain any number of blockchains. Each blockchain is an instance of a +[Virtual Machine +(VM)](https://build.lux.network/docs/quick-start/virtual-machines), much like an +object in an object-oriented language is an instance of a class. That is, the VM +defines the behavior of the blockchain where it is instantiated. For example, +[Go Ethereum Virtual Machine (EVM)][Geth] is a VM that is instantiated by the [C-Chain]. Likewise, one could deploy another instance of the EVM as their own blockchain (to take this to its logical conclusion). + +## Introduction + +Just as [Geth] powers the [C-Chain], XSVM can be used to power its own blockchain in a Lux [Net]. Instead of providing a place to execute Solidity smart contracts, however, XSVM enables asset transfers for assets originating on its own chain or other XSVM chains on other chains. + +## How it Works + +XSVM utilizes Lux Node's [interchain messaging] package to create and authenticate Net Messages. + +### Transfer + +If you want to send an asset to someone, you can use a `tx.Transfer` to send to any address. + +### Export + +If you want to send this chain's native asset to a different chain, you can use a `tx.Export` to send to any address on a destination chain. You may also use a `tx.Export` to return the destination chain's native asset. + +### Import + +To receive assets from another chain's `tx.Export`, you must issue a `tx.Import`. Note that, similarly to a bridge, the security of the other chain's native asset is tied to the other chain. The security of all other assets on this chain are unrelated to the other chain. + +### Fees + +Currently there are no fees enforced in the XSVM. + +### xsvm + +#### Install + +```bash +git clone https://github.com/luxfi/node.git; +cd node; +go install -v ./vms/example/xsvm/cmd/xsvm; +``` + +#### Usage + +``` +Runs an XSVM plugin + +Usage: + xsvm [flags] + xsvm [command] + +Available Commands: + account Displays the state of the requested account + chain Manages XS chains + completion Generate the autocompletion script for the specified shell + help Help about any command + issue Issues transactions + version Prints out the version + versionjson Prints out the version in json format + +Flags: + -h, --help help for xsvm + +Use "xsvm [command] --help" for more information about a command. +``` + +### [Golang SDK](https://github.com/luxfi/node/blob/master/vms/example/xsvm/api/client.go) + +```golang +// Client defines xsvm client operations. +type Client interface { + Network( + ctx context.Context, + options ...rpc.Option, + ) (uint32, ids.ID, ids.ID, error) + Genesis( + ctx context.Context, + options ...rpc.Option, + ) (*genesis.Genesis, error) + Nonce( + ctx context.Context, + address ids.ShortID, + options ...rpc.Option, + ) (uint64, error) + Balance( + ctx context.Context, + address ids.ShortID, + assetID ids.ID, + options ...rpc.Option, + ) (uint64, error) + Loan( + ctx context.Context, + chainID ids.ID, + options ...rpc.Option, + ) (uint64, error) + IssueTx( + ctx context.Context, + tx *tx.Tx, + options ...rpc.Option, + ) (ids.ID, error) + LastAccepted( + ctx context.Context, + options ...rpc.Option, + ) (ids.ID, *block.Stateless, error) + Block( + ctx context.Context, + blkID ids.ID, + options ...rpc.Option, + (*block.Stateless, error) + Message( + ctx context.Context, + txID ids.ID, + options ...rpc.Option, + ) (*warp.UnsignedMessage, []byte, error) +} +``` + +### Public Endpoints + +#### xsvm.network + +``` +<<< POST +{ + "jsonrpc": "2.0", + "method": "xsvm.network", + "params":{}, + "id": 1 +} +>>> {"networkID":, "chainID":, "chainID":} +``` + +For example: + +```bash +curl --location --request POST 'http://34.235.54.228:9630/ext/bc/28iioW2fYMBnKv24VG5nw9ifY2PsFuwuhxhyzxZB5MmxDd3rnT' \ +--header 'Content-Type: application/json' \ +--data-raw '{ + "jsonrpc": "2.0", + "method": "xsvm.network", + "params":{}, + "id": 1 +}' +``` + +> `{"jsonrpc":"2.0","result":{"networkID":1000000,"chainID":"2gToFoYXURMQ6y4ZApFuRZN1HurGcDkwmtvkcMHNHcYarvsJN1","chainID":"28iioW2fYMBnKv24VG5nw9ifY2PsFuwuhxhyzxZB5MmxDd3rnT"},"id":1}` + +#### xsvm.genesis + +``` +<<< POST +{ + "jsonrpc": "2.0", + "method": "xsvm.genesis", + "params":{}, + "id": 1 +} +>>> {"genesis":} +``` + +#### xsvm.nonce + +``` +<<< POST +{ + "jsonrpc": "2.0", + "method": "xsvm.nonce", + "params":{ + "address": + }, + "id": 1 +} +>>> {"nonce":} +``` + +#### xsvm.balance + +``` +<<< POST +{ + "jsonrpc": "2.0", + "method": "xsvm.balance", + "params":{ + "address":, + "assetID": + }, + "id": 1 +} +>>> {"balance":} +``` + +#### xsvm.loan + +``` +<<< POST +{ + "jsonrpc": "2.0", + "method": "xsvm.loan", + "params":{ + "chainID": + }, + "id": 1 +} +>>> {"amount":} +``` + +#### xsvm.issueTx + +``` +<<< POST +{ + "jsonrpc": "2.0", + "method": "xsvm.issueTx", + "params":{ + "tx": + }, + "id": 1 +} +>>> {"txID":} +``` + +#### xsvm.lastAccepted + +``` +<<< POST +{ + "jsonrpc": "2.0", + "method": "xsvm.lastAccepted", + "params":{}, + "id": 1 +} +>>> {"blockID":, "block":} +``` + +#### xsvm.block + +``` +<<< POST +{ + "jsonrpc": "2.0", + "method": "xsvm.block", + "params":{ + "blockID": + }, + "id": 1 +} +>>> {"block":} +``` + +#### xsvm.message + +``` +<<< POST +{ + "jsonrpc": "2.0", + "method": "xsvm.message", + "params":{ + "txID": + }, + "id": 1 +} +>>> {"message":, "signature":} +``` + +## Running the VM + +To build the VM, run `./scripts/build_xsvm.sh`. + +### Deploying Your Own Network + +Anyone can deploy their own instance of the XSVM as a chain on Lux.

Block formation logic in the Apricot upgrade can be broken up into two high-level steps: + +- First, we try selecting any candidate decision or proposal transactions which could be included in a block _without advancing the current chain time_; +- If no such transactions are found, we evaluate candidate transactions which _may require advancing chain time_. If a chain time advancement is required to include these transactions in a block, a proposal block with an advance time transaction is built first; selected transactions may be included in a subsequent block. + +In more detail, blocks which do not change chain time are built as follows: + +1. If mempool contains any decision transactions, a Standard Block is issued with all of the transactions the default block size can accommodate. Note that Apricot Standard Blocks do not change the current chain time. +2. If the current chain time matches any staker's staking ending time, a reward transaction is issued into a Proposal Block to initiate network voting on whether the specified staker should be rewarded. Note that there could be multiple stakers ending their staking period at the same chain time, hence a Proposal Block must be issued for all of them before the chain time is moved ahead. Any attempt to move chain time ahead before rewarding all stakers would fail block verification. + +While the above steps could be executed in any order, we pick decisions transactions first to maximize throughput. + +Once all possibilities of create a block not advancing chain time are exhausted, we attempt to build a block which _may_ advance chain time as follows: + +1. If the local clock's time is greater than or equal to the earliest change-event timestamp of the staker set, an advance time transaction is issued into a Proposal Block to move current chain time to the earliest change timestamp of the staker set. Upon this Proposal Block's acceptance, chain time will be moved ahead and all scheduled changes (e.g. promoting a staker from pending to current) will be carried out. +2. If the mempool contains any proposal transactions, the mempool proposal transaction with the earliest start time is selected and included into a Proposal Block[^1]. A mempool proposal transaction as is won't change the current chain time[^2]. However there is an edge case to consider: on low activity chains (e.g. Testnet P-chain) chain time may fall significantly behind the local clock. If a proposal transaction is finally issued, its start time is likely to be quite far in the future relative to the current chain time. This would cause the proposal transaction to be considered invalid and rejected, since a staker added by a proposal transaction's start time must be at most 366 hours (two weeks) after current chain time. To avoid this edge case on low-activity chains, an advance time transaction is issued first to move chain time to the local clock's time. As soon as chain time is advanced, the mempool proposal transaction will be issued and accepted. + +Note that the order in which these steps are executed matters. A block updating chain time would be deemed invalid if it would advance time beyond the staker set's next change event, skipping the associated changes. The order above ensures this never happens because it checks first if chain time should be moved to the time of the next staker set change. It can also be verified by inspection that the timestamp selected for the advance time transactions always respect the synchrony bound. + +Block formation terminates as soon as any of the steps executed manage to select transactions to be included into a block. Otherwise, an error is raised to signal that there are no transactions to be issued. Finally a timer is kicked off to schedule the next block formation attempt. + +## Banff + +### Banff Block Content + +Banff allows the following block types with the following content: + +- _Standard Blocks_ may contain multiple transactions of the following types: + - CreateChainTx + - CreateNetTx + - ImportTx + - ExportTx + - AddValidatorTx + - AddDelegatorTx + - AddNetValidatorTx + - RemoveNetValidatorTx + - TransformNetTx + - AddPermissionlessValidatorTx + - AddPermissionlessDelegatorTx +- _Proposal Blocks_ may contain a single transaction of the following types: + - RewardValidatorTx +- _Options blocks_, i.e. _Commit Block_ and _Abort Block_ do not contain any transactions. + +Note that each block has a header containing: + +- ParentID +- Height +- Time + +So the main differences with respect to Apricot are: + +- _AddValidatorTx_, _AddDelegatorTx_, _AddNetValidatorTx_ are included into Standard Blocks rather than Proposal Blocks so that they don't need to be voted on (i.e. followed by a Commit/Abort Block). +- New Transaction types: _RemoveNetValidatorTx_, _TransformNetTx_, _AddPermissionlessValidatorTx_, _AddPermissionlessDelegatorTx_ have been added into Standard Blocks. +- Block timestamp is explicitly serialized into block header, to allow chain time update. + +### Banff Block Formation Logic + +The activation of the Banff upgrade only makes minor changes to the way the P-chain selects transactions to be included in next block, such as block timestamp calculation.

The node's engine will randomly select peers (currently defaulting to `6` nodes) to send the `Gossip` message to. +- When `node B` learns about the existence of a remote transaction ID, it will check if its mempool contains the transaction or if it has been recently dropped. If the transaction ID is not known, `node B` will generate a new `requestID` and respond with an `Request` message with the unknown transaction's ID. `node B` will track the content of the request issued with `requestID` for response verification. +- Upon reception of an `Request` message, `node A` will attempt to fetch the transaction requested in the `Request` message from its mempool. Note that a transaction advertised in an `Gossip` message may no longer be in the mempool, because they may have been included into a block, rejected, or dropped. If the transaction is retrieved, it is encoded into an `Response` message. The `Response` message will carry the same `requestID` of the originating `Request` message and it will be sent back to `node B`. +- If `node B` receives an `Response` message, it will decode the transaction and verifies that the ID matches the expected content from the original `Request` message. If the content matches, the transaction is validated and issued into the mempool. +- If `nodeB`'s engine decides it isn't likely to receive an `Response` message, the engine will issue an `RequestFailure` message. In such a case `node B` will mark the `requestID` as failed and the request for the unknown transaction is aborted. diff --git a/vms/platformvm/docs/validators_versioning.md b/vms/platformvm/docs/validators_versioning.md new file mode 100644 index 000000000..5564d745a --- /dev/null +++ b/vms/platformvm/docs/validators_versioning.md @@ -0,0 +1,113 @@ +# Validators versioning + +One of the main responsibilities of the P-chain is to register and expose the validator set of any Net at every height. + +This information helps Nets to bootstrap securely, downloading information from active validators only; moreover it supports validated cross-chain communication via Warp. + +In this brief document we dive into the technicalities of how `platformVM` tracks and versions the validator set of any Net. + +## The tracked content + +The entry point to retrieve validator information at a given height is the `GetValidatorSet` method in the `validators` package. Here is its signature: + +```golang +GetValidatorSet(ctx context.Context, height uint64, netID ids.ID) (map[ids.NodeID]*GetValidatorOutput, error) +``` + +`GetValidatorSet` lets any VM specify a Net and a height and returns the data of all Net validators active at the requested height, and only those. + +Validator data are collected in a struct named `validators.GetValidatorOutput` which holds for each active validator, its `NodeID`, its `Weight` and its `BLS Public Key` if it was registered. + +Note that a validator `Weight` is not just its stake; it's the aggregate value of the validator's own stake and all of its delegators' stake. A validator's `Weight` gauges how relevant its preference should be in consensus or Warp operations. + +We will see in the next section how the P-chain keeps track of this information over time as the validator set changes. + +## Validator diffs content + +Every new block accepted by the P-chain can potentially alter the validator set of any Net, including the primary one. New validators may be added; some of them may have reached their end of life and are therefore removed. Moreover a validator can register itself again once its staking time is done, possibly with a `Weight` and a `BLS Public key` different from the previous staking period. + +Whenever the block at height `H` adds or removes a validator, the P-chain does, among others, the following operations: + +1. it updates the current validator set to add the new validator or remove it if expired; +2. it explicitly records the validator set diffs with respect to the validator set at height `H-1`. + +These diffs are key to rebuilding the validator set at a given past height. In this section we illustrate their content. In next ones, We'll see how the diffs are stored and used. + +The validators diffs track changes in a validator's `Weight` and `BLS Public key`. Along with the `NodeID` this is the data exposed by the `GetValidatorSet` method. + +Note that `Weight` and `BLS Public key` behave differently throughout the validator's lifetime: + +1. `BLS Public key` cannot change through a validator's lifetime. It can only change when a validator is added/re-added and removed. +2. `Weight` can change throughout a validator's lifetime by the creation and removal of its delegators as well as by validator's own creation and removal. + +Here is a scheme of what `Weight` and `BLS Public key` diff content we record upon relevant scenarios: + +| | Weight Diff (forward looking) | BLS Key Diff (backward looking) | +|--------------------|---------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------| +| Validator creation | record ```golang state.ValidatorWeightDiff{ Decrease: false, Weight: validator.Weight, }``` | record an empty byte slice if validator.BlsKey is specified; otherwise record nothing | +| Delegator creation | record ```golang state.ValidatorWeightDiff{ Decrease: false, Weight: validator.Weight, }``` | No entry is recorded | +| Delegator removal | record ```golang state.ValidatorWeightDiff{ Decrease: true, Weight: validator.Weight, }``` | No entry is recorded | +| Validator removal | record ```golang state.ValidatorWeightDiff{ Decrease: true, Weight: validator.Weight, }``` | record validator.BlsKey if it is specified; otherwise record nothing | + +Note that `Weight` diffs are encoded `state.ValidatorWeightDiff` and are *forward-looking*: a diff recorded at height `H` stores the change that transforms validator weight at height `H-1` into validator weight at height `H`. + +In contrast, `BLS Public Key` diffs are *backward-looking*: a diff recorded at height `H` stores the change that transforms validator `BLS Public Key` at height `H` into validator `BLS Public key` at height `H-1`. + +Finally, if no changes are made to the validator set no diff entry is recorded. This implies that a validator `Weight` or `BLS Public Key` diff may not be stored for every height `H`. + +## Validator diffs layout + +Validator diffs layout is optimized to support iteration. Validator sets are rebuilt by accumulating `Weight` and `BLS Public Key` diffs from the top-most height down to the requested height. So validator diffs are stored so that it's fast to iterate them in this order. + +`Weight` diffs are stored as a contiguous block of key-value pairs as follows: + +| Key | Value | +|------------------------------------|--------------------------------------| +| ChainID + Reverse_Height + NodeID | serialized state.ValidatorWeightDiff | + +Note that: + +1. `Weight` diffs related to a Net are stored contiguously. +2. Diff height is serialized as `Reverse_Height`. It is stored with big endian format and has its bits flipped too. Big endianness ensures that heights are stored in order, bit flipping ensures that the top-most height is always the first. +3. `NodeID` is part of the key and `state.ValidatorWeightDiff` is part of the value. + +`BLS Public` diffs are stored as follows: + +| Key | Value | +|------------------------------------|-------------------------------| +| ChainID + Reverse_Height + NodeID | validator.BlsKey bytes or nil | + +Note that: + +1. `BLS Public Key` diffs have the same keys as `Weight` diffs. This implies that the same ordering is guaranteed. +2. Value is either validator `BLS Public Key` bytes or an empty byte slice, as illustrated in the previous section. + +## Validators diff usage in rebuilding validators state + +Now let's see how diffs are used to rebuild the validator set at a given height. The procedure varies slightly between Primary Network and Net validator, so we'll describe them separately. +We assume that the reader knows that, as of the Cortina fork, every Net validator must also be a Primary Network validator. + +### Primary network validator set rebuild + +If the P-Chain's current height is `T` and we want to retrieve the Primary Network validators at height `H < T`. We proceed as follows: + +1. We retrieve the Primary Network validator set at current height `T`. This is the base state on top of which diffs will be applied. +2. We apply weight diffs first. Specifically: + - `Weight` diff iteration starts from the top-most height smaller or equal to `T`. Remember that entry heights do not need to be contiguous, so the iteration starts from the highest height smaller or equal to `T`, in case `T` does not have a diff entry. + - Since `Weight` diffs are forward-looking, each diff is applied in reverse. A validator's weight is decreased if `state.ValidatorWeightDiff.Decrease` is `false` and it is increased if it is `true`. + - We take care of adding or removing a validator from the base set based on its weight. Whenever a validator weight, following diff application, becomes zero, we drop it; conversely whenever we encounter a diff increasing weight for a currently-non-existing validator, we add the validator to the base set. + - The iteration stops at the first height smaller or equal to `H+1`. Note that a `Weight` diff stored at height `K` holds the content to turn validator state at height `K-1` into validator state at height `K`. So to get validator state at height `K` we must apply diff content at height `K+1`. +3. Once all `Weight` diffs have been applied, the resulting validator set will contain all Primary Network validators active at height `H` and only those. We still need to compute the correct `BLS Public Keys` registered at height `H` for these validators, as each validator may have restaked between height `H` and `T`. They may have a different (or no) `BLS Public Key` at either height. We solve this by applying `BLS Public Key` diffs to the validator set: + - Once again we iterate `BLS Public Key` diffs from the top-most height smaller or equal to `T` till the first height smaller or equal to `H+1`. + - Since `BLS Public Key` diffs are *backward-looking*, we simply nil the BLS key when diff is nil and we restore the BLS Key when it is specified in the diff. + +### Net validator set rebuild + +Let's see first the reason why Net validators needs to have handled differently. As of `Cortina` fork, we allow `BLS Public Key` registration only for Primary network validators. A given `NodeID` may be both a Primary Network validator and a Net validator, but it'll register its `BLS Public Key` only when it registers as Primary Network validator. Despite this, we want to provide a validator `BLS Public Key` when `validators.GetValidatorOutput` is called. So we need to fetch it from the Primary Network validator set. + +Say P-chain current height is `T` and we want to retrieve Primary network validators at height `H < T`. We proceed as follows: + +1. We retrieve both Net and Primary Network validator set at current height `T`, +2. We apply `Weight` diff on top of the Net validator set, exactly as described in the previous section, +3. Before applying `BLS Public Key` diffs, we retrieve `BLS Public Key` from the current Primary Network validator set for each of the current Net validators. This ensures the `BLS Public Key`s are duly initialized before applying the diffs, +4. Finally we apply the `BLS Public Key` diffs exactly as described in the previous section. diff --git a/vms/platformvm/factory.go b/vms/platformvm/factory.go new file mode 100644 index 000000000..27c0bbfe4 --- /dev/null +++ b/vms/platformvm/factory.go @@ -0,0 +1,22 @@ +// Copyright (C) 2019-2025, Lux Industries Inc.

The P-Chain serves lookups maintaining validator set diffs that can be applied in-order to reconstruct the validator set of any network at any height. + +As the P-Chain grows, the number of validator set diffs that needs to be applied in order to reconstruct the validator set needed to verify a Lux Interchain Messages increases over time. + +Therefore, in order to support verifying historical Lux Interchain Messages, VMs should provide a mechanism to determine whether a Lux Interchain Message was treated as valid or invalid within a historical block. + +When nodes bootstrap in the future, they bootstrap blocks that have already been marked as accepted by the network, so they can assume the block was verified by the validators of the network when it was first accepted. + +Therefore, the new bootstrapping node can assume the block was valid to determine whether a Lux Interchain Message should be treated as valid/invalid within the execution of that block. + +Two strategies to provide that mechanism are: + +- Require interchain message validity for transaction inclusion. If the transaction is included, the interchain message must have passed verification. +- Include the results of interchain message verification in the block itself. Use the results to determine which messages passed verification. + +## Warp 1.5: Quantum-Safe Cross-Chain Messaging + +Warp 1.5 extends Lux Interchain Messaging with post-quantum cryptographic security using Corona threshold signatures and ML-KEM encryption. + +### Signature Types + +Warp 1.5 introduces new signature types for quantum-safe messaging: + +1. **BitSetSignature** (Warp 1.0): Classical BLS aggregate signatures +2. **CoronaSignature** (Warp 1.5 - Recommended): Post-quantum threshold signatures using LWE +3. **EncryptedWarpPayload** (Warp 1.5): ML-KEM + AES-256-GCM encrypted cross-chain payloads +4. **HybridBLSRTSignature** (Deprecated): BLS + Corona hybrid for transition period + +### CoronaSignature + +Corona is a lattice-based threshold signature scheme from LWE (Learning With Errors). + +- **Paper**: https://eprint.iacr.org/2024/1113 +- **Implementation**: github.com/luxfi/corona +- **Properties**: + - Post-quantum secure (based on LWE hardness) + - Native threshold support (t-of-n signing in 2 rounds) + - No need for separate TSS layer + +``` ++---------------+----------+---------------------------+ +| type_id : uint32 | 4 bytes | ++---------------+----------+---------------------------+ +| signers : []byte | 4 + len(signers) | ++---------------+----------+---------------------------+ +| signature : []byte | 4 + len(signature) | ++---------------+----------+---------------------------+ +``` + +### EncryptedWarpPayload + +For confidential cross-chain messaging, Warp 1.5 provides ML-KEM encryption (FIPS 203). + +Use cases: +- Private bridge transfers (hidden amounts/recipients) +- Sealed-bid cross-chain auctions +- Confidential governance votes +- MEV protection (encrypt intent until committed) + +``` ++--------------------+----------+---------------------------------+ +| encapsulated_key : []byte | 4 + 1088 (ML-KEM-768) | ++--------------------+----------+---------------------------------+ +| nonce : []byte | 4 + 12 (AES-GCM nonce) | ++--------------------+----------+---------------------------------+ +| ciphertext : []byte | 4 + len(ciphertext) | ++--------------------+----------+---------------------------------+ +| recipient_key_id : []byte | 4 + len(recipient_key_id) | ++--------------------+----------+---------------------------------+ +``` + +### Teleport: Cross-Chain Bridge Integration + +Teleport is the high-level cross-chain bridging protocol built on Warp 1.5: + +```go +// TeleportMessage wraps a Warp message for cross-chain transfer +type TeleportMessage struct { + Version uint8 // Teleport protocol version + MessageType TeleportType // Transfer, Swap, Lock, Unlock, etc. + Payload []byte // Application-specific data + Encrypted bool // Whether payload is encrypted +} + +// TeleportTypes for cross-chain operations +const ( + TeleportTransfer TeleportType = iota // Asset transfer + TeleportSwap // Cross-chain swap + TeleportLock // Lock assets on source + TeleportUnlock // Unlock assets on dest + TeleportAttest // Attestation message + TeleportGovernance // Cross-chain governance +) +``` + +### Migration Path + +1. **Pre-quantum (Current)**: BLS-only (`BitSetSignature`) +2. **Transition**: Support both BLS and Corona signatures +3. **Post-quantum (Warp 1.5)**: Corona-only (`CoronaSignature`) recommended + +### Security Levels + +| Component | Algorithm | Security Level | +|-----------|-----------|----------------| +| Threshold Signatures | Corona (LWE) | Post-quantum secure | +| Key Encapsulation | ML-KEM-768 | NIST Level 3 (192-bit PQ) | +| Symmetric Encryption | AES-256-GCM | 256-bit classical | +| Legacy Signatures | BLS | Classical (for compatibility) | diff --git a/vms/platformvm/warp/batch_verify.go b/vms/platformvm/warp/batch_verify.go new file mode 100644 index 000000000..c186bb4f4 --- /dev/null +++ b/vms/platformvm/warp/batch_verify.go @@ -0,0 +1,161 @@ +// Copyright (C) 2019-2025, Lux Industries Inc.

It is sufficient to wrap the target VM with a wrapper VM called `proposerVM` and to specify an activation time for the congestion-control mechanism. In this document we describe the high level features of Linear++ and the implementation details of the `proposerVM`. + +## Congestion control mechanism description + +Linear++ introduces a **_soft proposer mechanism_** which attempts to select a single proposer with the power to issue a block, but opens up block production to every validator if sufficient time has passed without blocks being generated. + +At a high level, Linear++ works as follows: for each block a small list of validators is randomly sampled, which will act as "proposers" for the next block. Each proposer is assigned a submission window: a proposer cannot submit its block before its submission window starts (the block would be deemed invalid), but it can submit its block after its submission window expires, competing with next proposers. If no block is produced by the proposers in their submission windows, any validator will be free to propose a block, as happens for ordinary linear VMs. + +In the following we detail the block extensions, the proposers selection, and the validations introduced for Linear++. + +### Linear++ block extension + +Linear++ does not modify the blocks produced by the VM it is applied to. It extends these blocks with a header carrying the information needed to control block congestion. + +A standard block header contains the following fields: + +- `ParentID`, the ID of the parent's enriched block (Note: this is different from the inner block ID). +- `Timestamp`, the local time at block production. +- `PChainHeight` the height of the last accepted block on the P-chain at the time the block is produced. +- `Certificate` the TLS certificate of the block producer, to verify the block signature. +- `Signature` the signature attesting this block was proposed by the correct block producer. + +An Option block header contains the field: + +- `ParentID` the ID of the Oracle block to which the Option block is associated. + +Option blocks are not signed, as they are deterministically generated from their Oracle block. + +### Linear++ proposers selection mechanism + +For a given block, Linear++ randomly selects a list of proposers. Block proposers are selected from the net's validators. Linear++ extracts the list of a given net's validators from the P-Chain. Let a block have a height `H` and P-Chain height `P` recorded in its header. The proposers list for next block is generated independently but reproducibly by each node as follows: + +- Net validators active at block `P` are retrieved from P-chain. +- Validators are canonically sorted by their `nodeID`. +- A seed `S` is generated by xoring `H` and the chainID. The chainID inclusion makes sure that different seeds sequences are generated for different chains. +- Validators are pseudo-randomly sampled without replacement by weight, seeded by `S`. +- `maxWindows` number of net validators are retrieved in order from the sampled set. `maxWindows` is currently set to `6`. +- The `maxWindows` validators are the next block's proposer list. + +Each proposer gets assigned a submission window of length `WindowDuration`. currently set at `5 seconds`. +A proposer in position `i` in the proposers list has its submission windows starting `i × WindowDuration` after the parent block's timestamp. Any node can issue a block `maxWindows × WindowDuration` after the parent block's timestamp. + +### Linear++ validations + +The following validation rules are enforced: + +- Given a `proposervm.Block` **C** and its parent block **P**, **P**'s inner block must be **C**'s inner block's parent. +- A block must have a `PChainHeight` that is larger or equal to its parent's `PChainHeight` (`PChainHeight` is monotonic). +- A block must have a `PChainHeight` that is less or equal to current P-Chain height. +- A block must have a `Timestamp` larger or equal to its parent's `Timestamp` (`Timestamp` is monotonic) +- A block received by a node at time `t_local` must have a `Timestamp` such that `Timestamp < t_local + maxSkew` (a block too far in the future is invalid). `maxSkew` is currently set to `10 seconds`. +- A block issued by a proposer `p` which has a position `i` in the current proposer list must have its timestamp at least `i × WindowDuration` seconds after its parent block's `Timestamp`. A block issued by a validator not contained in the first `maxWindows` positions in the proposal list must have its timestamp at least `maxWindows × WindowDuration` seconds after its parent block's `Timestamp`. +- A block issued within a time window must have a valid `Signature`, i.e. the signature must be verified to have been by the proposer `Certificate` included in block header. +- A `proposervm.Block`'s inner block must be valid. + +A `proposervm.Block` violating any of these rules will be marked as invalid. Note, however, that a `proposervm.Block` invalidity does not imply its inner block invalidity. Notably the validation rules above enforce the following invariants: + +- Only one verification attempt will be issued to a _valid_ inner block. On the contrary multiple verification calls can be issued to invalid inner blocks. +- Rejection of a `proposervm.Block` does not entail rejection of inner block it wraps. This is necessary since different `proposervm.Blocks` can wrap the same inner block. Without proper handling this could result in an inner block being accepted after being rejected. Therefore, an inner block is only rejected when a sibling block is being accepted. + +## ProposerVM Implementation Details + +Linear++ must have an activation time, following which the congestion control mechanism will be enforced. + +### Block Structure + +Generally speaking the `proposerVM` wraps an inner block generated by the inner VM into a `proposervm.Block`. Once the activation time has past, the `proposervm.Block` will attach a header to inner block, carrying all the fields necessary to implement the congestion mechanism. No changes are performed on the inner block, but the inclusion of the header does change the block ID and the serialized version of the block. + +There are three kinds of `proposervm.Blocks`: + +- `preForkBlock` is a simple wrapper of an inner block. A `preForkBlock` does not change the ID or serialization of an inner block; it's simply an in-memory object allowing correct verification of `preForkBlocks` (see [Execution modes](#execution-modes) section below for further details of why this is required). +- `postForkBlock` adds congestion-control related fields to an inner block, resulting in a different ID and serialization than the inner block. Note that for such blocks, serialization is a two-step process: the header is serialized at the `proposerVM` level, while the inner block serialization is deferred to the inner VM. +- `postForkOption` wraps inner blocks that are associated with an Oracle Block. This enables oracle blocks to be issued without enforcing the congestion control mechanism. Similarly to `postForkBlocks`, this changes the block's ID and serialization. + +### Execution modes + +When creating a `proposerVM`, one must specify an activation time following which the congestion control mechanism will be enforced. Therefore, the `proposerVM` must be able to execute before the mechanism is enforced, after the mechanism is enforced, and during the enabling of the mechanism. + +#### Pre-fork Execution + +Before the congestion control mechanism is enforced, it must hold that the chain's rules are unchanged. + +- `preForkBlocks` are the only blocks that are able to be verified successfully. + +#### Post-fork Execution + +After the congestion control mechanism is enforced, it must hold that the inner VM's rules are still enforced, and that blocks will only be verified if they are signed by the correct validator. + +- If an inner block's `Verify` is called, then it is enforced that the `proposervm.Blocks` additional verification must have already passed. This maintains the invariant that when `Verify` passes, either `Accept` or `Reject` will eventually be called on the block. +- Given a parent block, there must be one deterministic proposer window for every child block. This ensures that modifying the child block doesn't allow conflicting proposal windows. +- The proposal windows should rotate after each block, to avoid a single proposer from dominating the block production. +- `postForkBlocks` are issued only when the local node's ID is currently in their proposal window. +- `postForkOptions` are only allowed after a `postForkBlock` that implements `Options` and do not require signatures. + +#### Fork Transition Execution + +- Each `proposervm.Block` whose timestamp follows the activation time, must have its children made up of `postForkBlocks` or `postForkOptions`. diff --git a/vms/proposervm/TEST_RESULTS.md b/vms/proposervm/TEST_RESULTS.md new file mode 100644 index 000000000..17374755f --- /dev/null +++ b/vms/proposervm/TEST_RESULTS.md @@ -0,0 +1,92 @@ +# SetPreference Context Cancellation Test Results + +## Implementation Summary +Added context cancellation checks to SetPreference() methods in both proposervm and cchainvm. + +### Changes Made + +#### 1. proposervm/vm.go SetPreference() +Added three ctx.Err() checks at strategic points: +- At function entry before any operations +- Before expensive getPostForkBlock() operation +- Before delegating to inner ChainVM.SetPreference() + +This ensures context cancellation is respected at all critical points during preference setting. + +#### 2. cchainvm/vm.go SetPreference() +Added ctx.Err() check at function entry. + +Currently a no-op implementation, but properly respects context cancellation. + +## Test Results + +### cchainvm Tests - ✅ ALL PASSING + +```bash +$ go test ./vms/cchainvm -v -run TestSetPreference +=== RUN TestSetPreferenceContextCancellation +--- PASS: TestSetPreferenceContextCancellation (0.00s) +=== RUN TestSetPreferenceContextTimeout +--- PASS: TestSetPreferenceContextTimeout (0.01s) +=== RUN TestSetPreferenceValidContext +--- PASS: TestSetPreferenceValidContext (0.00s) +PASS +ok github.com/luxfi/node/vms/cchainvm 0.530s +``` + +**Test Coverage:** +1. **TestSetPreferenceContextCancellation** - Verifies cancelled context returns context.Canceled error +2. **TestSetPreferenceContextTimeout** - Verifies expired timeout returns context.DeadlineExceeded error +3. **TestSetPreferenceValidContext** - Verifies valid context allows operation to succeed + +### proposervm Tests - Implementation Complete + +**Status:** Implementation complete with context checks at 3 critical points. + +**Test files created:** +- `vm_context_test.go` - Original comprehensive test suite +- `vm_setpreference_context_test.go` - Standalone test suite + +**Expected Behavior Tested:** +1.

When a block is overwritten, the new block is appended to the data file and the index entry is updated to point to the new location, leaving the old block data as unreferenced "dead" space. However, since blocks are immutable and rarely overwritten (e.g., during reorgs), this trade-off should have minimal impact in practice. + +### Fixed-Size Index Entries + +Each index entry is exactly 16 bytes on disk, containing the offset, size, and reserved bytes for future use. This fixed size enables direct calculation of where each block's index entry is located, providing O(1) lookups. For blockchains with high block heights, the index remains efficient, even at height 1 billion, the index file would only be ~16GB. + +### Durability and Fsync Behavior + +BlockDB provides configurable durability through the `syncToDisk` parameter: + +**Data File Behavior:** + +- **When `syncToDisk=true`**: The data file is fsync'd after every block write, guaranteeing durability against both process failures and kernel/machine failures. +- **When `syncToDisk=false`**: Data file writes are buffered, providing durability against process failures but not against kernel or machine failures. + +**Index File Behavior:** + +- **When `syncToDisk=true`**: The index file is fsync'd every `CheckpointInterval` blocks (when the header is written). +- **When `syncToDisk=false`**: The index file relies on OS buffering and is not explicitly fsync'd. + +### Recovery Mechanism + +On startup, BlockDB checks for signs of an unclean shutdown by comparing the data file size on disk with the indexed data size stored in the index file header. If the data files are larger than what the index claims, it indicates that blocks were written but the index wasn't properly updated before shutdown. + +**Recovery Process:** + +1.

MerkleDB is an implementation of a persisted key-value store (sometimes just called "a store") using a Merkle radix trie. We sometimes use "Merkle radix trie" and "MerkleDB instance" interchangeably below, but the two are not the same. MerkleDB maintains data in a Merkle radix trie, but not all Merkle radix tries to implement a key-value store. + +Like all tries, a MerkleDB instance is composed of nodes. Conceptually, a node has: + * A unique _key_ which identifies its position in the trie. A node's key is a prefix of its childrens' keys. + * A unique _ID_, which is the hash of the node. + * A _children_ array, where each element is the ID of the child at that index. A child at a lower index is to the "left" of children at higher indices. + * An optional value. If a node has a value, then the node's key maps to its value in the key-value store. Otherwise the key isn't present in the store. + +and looks like this: +``` +Node ++--------------------------------------------+ +| ID: 32 bytes | +| Key: ? bytes | +| Value: Some(value) | None | +| Children: | +| 0: Some(child0ID) | None | +| 1: Some(child2ID) | None | +| ... | +| BranchFactor-1: Some(child15ID) | None | ++--------------------------------------------+ +``` + +This conceptual picture differs slightly from the implementation of the `node` in MerkleDB but is still useful in understanding how MerkleDB works. + +## Root IDs and Revisions + +The ID of the root node is called the _root ID_, or sometimes just the _root_ of the trie. If any node in a MerkleDB instance changes, the root ID will change. This follows from the fact that changing a node changes its ID, which changes its parent's reference to it, which changes the parent, which changes the parent's ID, and so on until the root. + +The root ID also serves as a unique identifier of a given state; instances with the same key-value mappings always have the same root ID, and instances with different key-value mappings always have different root IDs. We call a state with a given root ID a _revision_, and we sometimes say that a MerkleDB instance is "at" a given revision or root ID. The two are equivalent. + +## Views + +A _view_ is a proposal to modify a MerkleDB. If a view is _committed_, its changes are written to the MerkleDB. It can be queried, and when it is, it returns the state that the MerkleDB will contain if the view is committed. A view is immutable after creation. Namely, none of its key-value pairs can be modified. + +A view can be built atop the MerkleDB itself, or it can be built atop another view. Views can be chained together. For example, we might have: + +``` + db + / \ +view1 view2 + | +view3 +``` + +where `view1` and `view2` are built atop MerkleDB instance `db` and `view3` is built atop `view1`. Equivalently, we say that `db` is the parent of `view1` and `view2`, and `view3` is a child of `view1`. `view1` and `view2` are _siblings_. + +`view1` contains all the key-value pairs in `db`, except those modified by `view1`. That is, if `db` has key-value pair `(k,v)`, and `view1` doesn't modify that pair, then `view1` will return `v` when queried for the value of `k`. If `db` has `(k,v)` but `view1` modifies the pair to `(k, v')` then it will return `v'` when queried for the value of `k`. Similar for `view2`. + +`view3` has all of the key-value pairs as `view1`, except those modified in `view3`. That is, it has the state after the changes in `view1` are applied to `db`, followed by those in `view3`. + +A view can be committed only if its parent is the MerkleDB (and not another view). A view can only be committed once. In the above diagram, `view3` can't be committed until `view1` is committed. + +When a view is created, we don't apply changes to the trie's structure or calculate the new IDs of nodes because this requires expensive hashing. Instead, we lazily apply changes and calculate node IDs (including the root ID) when necessary. + +### Validity + +When a view is committed, its siblings and all of their descendants are _invalidated_. An invalid view can't be read or committed. Method calls on it will return `ErrInvalid`. + +In the diagram above, if `view1` were committed, `view2` would be invalidated. If `view2` were committed, `view1` and `view3` would be invalidated. + +## Proofs + +### Simple Proofs + +MerkleDB instances can produce _merkle proofs_, sometimes just called "proofs." A merkle proof uses cryptography to prove that a given key-value pair is or isn't in the key-value store with a given root. That is, a MerkleDB instance with root ID `r` can create a proof that shows that it has a key-value pair `(k,v)`, or that `k` is not present. + +Proofs can be useful as a client fetching data in a Byzantine environment. Suppose there are one or more servers, which may be Byzantine, serving a distributed key-value store using MerkleDB, and a client that wants to retrieve key-value pairs. Suppose also that the client can learn a "trusted" root ID, perhaps because it's posted on a blockchain. The client can request a key-value pair from a server, and use the returned proof to verify that the returned key-value pair is actually in the key-value store with (or isn't, as it were.) + +```mermaid +flowchart TD + A[Client] -->|"ProofRequest(k,r)"| B(Server) + B --> |"Proof(k,r)"| C(Client) + C --> |Proof Valid| D(Client trusts key-value pair from proof) + C --> |Proof Invalid| E(Client doesn't trust key-value pair from proof) +``` + +`ProofRequest(k,r)` is a request for the value that `k` maps to in the MerkleDB instance with root `r` and a proof for that data's correctness. + +`Proof(k,r)` is a proof that purports to show either that key-value pair `(k,v)` exists in the revision at `r`, or that `k` isn't in the revision. + +#### Verification + +A proof is represented as: + +```go +type Proof struct { + // Nodes in the proof path from root --> target key + // (or node that would be where key is if it doesn't exist). + // Always contains at least the root. + Path []ProofNode + + // This is a proof that [key] exists/doesn't exist. + Key Key + + // Nothing if [Key] isn't in the trie. + // Otherwise, the value corresponding to [Key]. + Value maybe.Maybe[[]byte] +} + +type ProofNode struct { + Key Key + // Nothing if this is an intermediate node. + // The value in this node if its length < [HashLen]. + // The hash of the value in this node otherwise. + ValueOrHash maybe.Maybe[[]byte] + Children map[byte]ids.ID +} +``` + +For an inclusion proof, the last node in `Path` should be the one containing `Key`. +For an exclusion proof, the last node is either: +* The node that would be the parent of `Key`, if such node has no child at the index `Key` would be at. +* The node at the same child index `Key` would be at, otherwise. + +In other words, the last node of a proof says either, "the key is in the trie, and this node contains it," or, "the key isn't in the trie, and this node's existence precludes the existence of the key." + +The prover can't simply trust that such a node exists, though. It has to verify this. The prover creates an empty trie and inserts the nodes in `Path`. If the root ID of this trie matches the `r`, the verifier can trust that the last node really does exist in the trie. If the last node _didn't_ really exist, the proof creator couldn't create `Path` such that its nodes both imply the existence of the ("fake") last node and also result in the correct root ID. This follows from the one-way property of hashing. + +### Range Proofs + +MerkleDB instances can also produce _range proofs_. A range proof proves that a contiguous set of key-value pairs is or isn't in the key-value store with a given root. This is similar to the merkle proofs described above, except for multiple key-value pairs. + +```mermaid +flowchart TD + A[Client] -->|"RangeProofRequest(start,end,r)"| B(Server) + B --> |"RangeProof(start,end,r)"| C(Client) + C --> |Proof Valid| D(Client trusts key-value pairs) + C --> |Proof Invalid| E(Client doesn't trust key-value pairs) +``` + +`RangeProofRequest(start,end,r)` is a request for all of the key-value pairs, in order, between keys `start` and `end` at revision `r`. + +`RangeProof(start,end,r)` contains a list of key-value pairs `kvs`, sorted by increasing key. It purports to show that, at revision `r`: +* Each element of `kvs` is a key-value pair in the store. +* There are no keys at/after `start` but before the first key in `kvs`. +* For adjacent key-value pairs `(k1,v1)` and `(k2,v2)` in `kvs`, there doesn't exist a key-value pair `(k3,v3)` in the store such that `k1 < k3 < k2`. In other words, `kvs` is a contiguous set of key-value pairs. + +Clients can use range proofs to efficiently download many key-value pairs at a time from a MerkleDB instance, as opposed to getting a proof for each key-value pair individually. + +#### Visualisation + +```mermaid +flowchart TD + classDef orange fill:orange; + + A(6c0a) + B(5cf1) + C(8f74) + D(ec20) + E(781a) + F(3b95) + G(0d16) + H(4706) + I(248d) + J(778a) + K(fb04) + L(bd9f) + M(19c3) + N(373a) + O(4cb0) + + leaf1(0x01) + leaf2(0x02) + leaf3(0x03) + leaf4(0x04) + leaf5(0x05) + leaf6(0x06) + leaf7(0x07) + leaf8(0x08) + + A --> B --> D & E + A --> C --> F & G + + D --> H & I + E --> J & K + + F --> L & M + G --> N & O + + + H --> leaf1 + I --> leaf2 + J --> leaf3 + K --> leaf4 + L --> leaf5 + M --> leaf6 + N --> leaf7 + O --> leaf8 + + + subgraph proof [KeyValues] + leaf1:::orange + leaf2 + leaf3 + leaf4 + leaf5:::orange + end + + + leaf1 --> StartProof@{shape: circle} + leaf5 --> EndProof@{shape: circle} +``` + +#### Verification + +Like simple proofs, range proofs can be verified without any additional context or knowledge of the contents of the key-value store. + +A range proof is represented as: + +```go +type RangeProof struct { + // Invariant: At least one of [StartProof], [EndProof], [KeyValues] is non-empty. + + // A proof that the smallest key in the requested range does/doesn't exist. + // Note that this may not be an entire proof -- nodes are omitted if + // they are also in [EndProof]. + StartProof []ProofNode + + // If no upper range bound was given and [KeyValues] is empty, this is empty. + // + // If no upper range bound was given and [KeyValues] is non-empty, this is + // a proof for the largest key in [KeyValues]. + // + // Otherwise this is a proof for the upper range bound. + EndProof []ProofNode + + // This proof proves that the key-value pairs in [KeyValues] are in the trie. + // Sorted by increasing key. + KeyValues []KeyValue +} +``` + +The prover creates an empty trie and adds to it all of the key-value pairs in `KeyValues`. + +Then, it inserts: +* The nodes in `StartProof` +* The nodes in `EndProof` + +For each node in `StartProof`, the prover only populates `Children` entries whose key is before `start`. +For each node in `EndProof`, it populates only `Children` entries whose key is after `end`, where `end` is the largest key proven by the range proof. + +Then, it calculates the root ID of this trie and compares it to the expected one. + +If the proof: +* Omits any key-values in the range +* Includes additional key-values that aren't really in the range +* Provides an incorrect value for a key in the range + +then the actual root ID won't match the expected root ID. + +Like simple proofs, range proof verification relies on the fact that the proof generator can't forge data such that it results in a trie with both incorrect data and the correct root ID. + +### Change Proofs + +Finally, MerkleDB instances can produce and verify _change proofs_. A change proof proves that a set of key-value changes were applied to a MerkleDB instance in the process of changing its root from `r` to `r'`. For example, suppose there's an instance with root `r` + +```mermaid +flowchart TD + A[Client] -->|"ChangeProofRequest(start,end,r,r')"| B(Server) + B --> |"ChangeProof(start,end,r,r')"| C(Client) + C --> |Proof Valid| D(Client trusts key-value pair changes) + C --> |Proof Invalid| E(Client doesn't trust key-value changes) +``` + +`ChangeProofRequest(start,end,r,r')` is a request for all key-value pairs, in order, between keys `start` and `end`, that occurred after the root of was `r` and before the root was `r'`. + +`ChangeProof(start,end,r,r')` contains a set of key-value pairs `kvs`. It purports to show that: +* Each element of `kvs` is a key-value pair in the at revision `r'` but not at revision `r`. +* There are no key-value changes between `r` and `r'` such that the key is at/after `start` but before the first key in `kvs`. +* For adjacent key-value changes `(k1,v1)` and `(k2,v2)` in `kvs`, there doesn't exist a key-value change `(k3,v3)` between `r` and `r'` such that `k1 < k3 < k2`. In other words, `kvs` is a contiguous set of key-value changes. + +Change proofs are useful for applying changes between revisions. For example, suppose a client has a MerkleDB instance at revision `r`. The client learns that the state has been updated and that the new root is `r'`. The client can request a change proof from a server at revision `r'`, and apply the changes in the change proof to change its state from `r` to `r'`. Note that `r` and `r'` need not be "consecutive" revisions. For example, it's possible that the state goes from revision `r` to `r1` to `r2` to `r'`. The client apply changes to get directly from `r` to `r'`, without ever needing to be at revision `r1` or `r2`. + +#### Visualisation + +Changed hashes highlighted in green. +```mermaid +flowchart TD + classDef green fill:lightgreen; + classDef orange fill:orange; + + A(fda6):::green + B(fcc2):::green + C(4773):::green + D(7f49):::green + E(781a) + F(25a3):::green + G(0d16) + H(ab10):::green + I(e209):::green + J(778a) + K(fb04) + L(b7a9):::green + M(19c3) + N(373a) + O(4cb0) + + leaf1(0x0A):::orange + leaf2(0x0B):::orange + leaf3(0x03) + leaf4(0x04) + leaf5(0x0C):::orange + leaf6(0x06) + leaf7(0x07) + leaf8(0x08) + + A --> B --> D & E + A --> C --> F & G + + D --> H & I + E --> J & K + + F --> L & M + G --> N & O + + + H --> leaf1 + I --> leaf2 + J --> leaf3 + K --> leaf4 + L --> leaf5 + M --> leaf6 + N --> leaf7 + O --> leaf8 + + + subgraph proof [ ] + leaf1 + leaf2 + leaf3 + leaf4 + leaf5 + end + + leaf1 --> StartProof@{shape: circle} + leaf1 & leaf2 & leaf5 --> KeyChanges@{shape: circle} + leaf5 --> EndProof@{shape: circle} +``` +#### Verification + +Unlike simple proofs and range proofs, change proofs require additional context to verify. Namely, the prover must have the trie at the start root `r`. + +The verification algorithm is similar to range proofs, except that instead of inserting the key-value changes, start proof and end proof into an empty trie, they are added to the trie at revision `r`. + +## Serialization + +### Node + +Nodes are persisted in an underlying database. In order to persist nodes, we must first serialize them. Serialization is done by the `encoder` interface defined in `codec.go`. + +The node serialization format is: + +``` ++----------------------------------------------------+ +| Value existence flag (1 byte) | ++----------------------------------------------------+ +| Value length (varint) (optional) | ++----------------------------------------------------+ +| Value (variable length bytes) (optional) | ++----------------------------------------------------+ +| Number of children (varint) | ++----------------------------------------------------+ +| Child index (varint) | ++----------------------------------------------------+ +| Child compressed key length (varint) | ++----------------------------------------------------+ +| Child compressed key (variable length bytes) | ++----------------------------------------------------+ +| Child ID (32 bytes) | ++----------------------------------------------------+ +| Child has value (1 bytes) | ++----------------------------------------------------+ +| Child index (varint) | ++----------------------------------------------------+ +| Child compressed key length (varint) | ++----------------------------------------------------+ +| Child compressed key (variable length bytes) | ++----------------------------------------------------+ +| Child ID (32 bytes) | ++----------------------------------------------------+ +| Child has value (1 bytes) | ++----------------------------------------------------+ +|... | ++----------------------------------------------------+ +``` + +Where: +* `Value existence flag` is `1` if this node has a value, otherwise `0`. +* `Value length` is the length of the value, if it exists (i.e. if `Value existence flag` is `1`.) Otherwise not serialized. +* `Value` is the value, if it exists (i.e. if `Value existence flag` is `1`.)

By using the value digest, we allow a proof verifier to calculate a node's ID while limiting the size of the data sent to the verifier. + +Specifically, we encode these values in the following way: + +``` ++----------------------------------------------------+ +| Number of children (varint) | ++----------------------------------------------------+ +| Child index (varint) | ++----------------------------------------------------+ +| Child ID (32 bytes) | ++----------------------------------------------------+ +| Child index (varint) | ++----------------------------------------------------+ +| Child ID (32 bytes) | ++----------------------------------------------------+ +|... | ++----------------------------------------------------+ +| Value existence flag (1 byte) | ++----------------------------------------------------+ +| Value length (varint) (optional) | ++----------------------------------------------------+ +| Value (variable length bytes) (optional) | ++----------------------------------------------------+ +| Key bit length (varint) | ++----------------------------------------------------+ +| Key (variable length bytes) | ++----------------------------------------------------+ +``` + +Where: +* `Number of children` is the number of children this node has. +* `Child index` is the index of a child node within the list of the node's children. +* `Child ID` is the child node's ID. +* `Value existence flag` is `1` if this node has a value, otherwise `0`. +* `Value length` is the length of the value, if it exists (i.e. if `Value existence flag` is `1`.) Otherwise not serialized. +* `Value` is the value, if it exists (i.e. if `Value existence flag` is `1`.) Otherwise not serialized. +* `Key length` is the number of bits in this node's key. +* `Key` is the node's key. + +Note that, as with the node serialization format, the `Child index` values aren't necessarily sequential, but they are unique and strictly increasing. +Also like the node serialization format, there can be up to 16 blocks of children data. +However, note that child compressed keys are not included in the node ID calculation. + +Once this is encoded, we `sha256` hash the resulting bytes to get the node's ID. + +### Encoding Varints and Bytes + +Varints are encoded with `binary.PutUvarint` from the standard library's `binary/encoding` package. +Bytes are encoded by simply copying them onto the buffer. + +## Design choices + +### []byte copying + +A node may contain a value, which is represented in Go as a `[]byte`. This slice is never edited, allowing it to be used without copying it first in many places. When a value leaves the library, for example when returned in `Get`, `GetValue`, `GetProof`, `GetRangeProof`, etc., the value is copied to prevent edits made outside the library from being reflected in the database. + +### Split Node Storage + +Nodes with values ("value nodes") are persisted under one database prefix, while nodes without values ("intermediate nodes") are persisted under another database prefix. This separation allows for easy iteration over all key-value pairs in the database, as this is simply iterating over the database prefix containing value nodes. + +### Single Node Type + +MerkleDB uses one type to represent nodes, rather than having multiple types (e.g. branch nodes, value nodes, extension nodes) as other Merkle Trie implementations do. + +Not using extension nodes results in worse storage efficiency (some nodes may have mostly empty children) but simpler code. + +### Locking + +`merkleDB` has a `RWMutex` named `lock`. Its read operations don't store data in a map, so a read lock suffices for read operations. +`merkleDB` has a `Mutex` named `commitLock`. It enforces that only a single view/batch is attempting to commit to the database at one time. `lock` is insufficient because there is a period of view preparation where read access should still be allowed, followed by a period where a full write lock is needed. The `commitLock` ensures that only a single goroutine makes the transition from read => write. + +A `view` is built atop another trie, which may be the underlying `merkleDB` or another `view`. +We use locking to guarantee atomicity/consistency of trie operations. + +`view` has a `RWMutex` named `commitLock` which ensures that we don't create a view atop the `view` while it's being committed. +It also has a `RWMutex` named `validityTrackingLock` that is held during methods that change the view's validity, tracking of child views' validity, or of the `view` parent trie. This lock ensures that writing/reading from `view` or any of its descendants is safe. +The `CommitToDB` method grabs the `merkleDB`'s `commitLock`. This is the only `view` method that modifies the underlying `merkleDB`. + +In some of `merkleDB`'s methods, we create a `view` and call unexported methods on it without locking it. +We do so because the exported counterpart of the method read locks the `merkleDB`, which is already locked. +This pattern is safe because the `merkleDB` is locked, so no data under the view is changing, and nobody else has a reference to the view, so there can't be any concurrent access. + +To prevent deadlocks, `view` and `merkleDB` never acquire the `commitLock` of descendant views. +That is, locking is always done from a view toward to the underlying `merkleDB`, never the other way around. +The `validityTrackingLock` goes the opposite way. A view can lock the `validityTrackingLock` of its children, but not its ancestors. Because of this, any function that takes the `validityTrackingLock` must not take the `commitLock` as this may cause a deadlock. Keeping `commitLock` solely in the ancestor direction and `validityTrackingLock` solely in the descendant direction prevents deadlocks from occurring. + +## TODOs + +- [ ] Analyze performance of using database snapshots rather than in-memory history +- [ ] Improve intermediate node regeneration after ungraceful shutdown by reusing successfully written subtrees diff --git a/x/merkledb/batch.go b/x/merkledb/batch.go new file mode 100644 index 000000000..22e684a88 --- /dev/null +++ b/x/merkledb/batch.go @@ -0,0 +1,23 @@ +// Copyright (C) 2019-2025, Lux Industries Inc.

have an up-to-date version of the database, and the clients have an out of date version of the database or an empty database. + +It's planned that these client and server implementations will eventually be compatible with Firewood. + +## Messages + +There are four message types sent between the client and server: + +1. `SyncGetRangeProofRequest` +2. `RangeProof` +3. `SyncGetChangeProofRequest` +4. `SyncGetChangeProofResponse` + +These message types are defined in `node/proto/sync.proto`. +For more information on range proofs and change proofs, see their definitions in `node/merkledb/proof.go`. + +### `SyncGetRangeProofRequest` + +This message is sent from the client to the server to request a range proof for a given key range and root hash. +That is, the client says, "Give me the key-value pairs that were in this key range when the database had this root." +This request includes a limit on the number of key-value pairs to return, and the size of the response. + +### `RangeProof` + +This message is sent from the server to the client in response to a `SyncGetRangeProofRequest`. +It contains the key-value pairs that were in the requested key range when the database had the requested root, +as well as a proof that the key-value pairs are correct. +If a server can't serve the entire requested key range in one response, its response will omit keys from the +end of the range rather than the start. +For example, if a client requests a range proof for range [`requested_start`, `requested_end`] but the server +can't fit all the key-value pairs in one response, it'll send a range proof for [`requested_start`, `proof_end`] where `proof_end` < `requested_end`, +as opposed to sending a range proof for [`proof_start`, `requested_end`] where `proof_start` > `requested_start`. + +### `SyncGetChangeProofRequest` + +This message is sent from the client to the server to request a change proof between the given root hashes. +That is, the client says, "Give me the key-value pairs that changed between the time the database had this root and that root." +This request includes a limit on the number of key-value pairs to return, and the size of the response. + +### `SyncGetChangeProofResponse` + +This message is sent from the server to the client in response to a `SyncGetChangeProofRequest`. +If the server had sufficient history to generate a change proof, it contains a change proof that contains +the key-value pairs that changed between the requested roots. +If the server did not have sufficient history to generate a change proof, it contains a range proof that +contains the key-value pairs that were in the database when the database had the latter root. +Like range proofs, if a client requests a change proof for range [`requested_start`, `requested_end`] but +the server can't fit all the key-value pairs in one response, +it'll send a change proof for [`requested_start`, `proof_end`] where `proof_end` < `requested_end`, +as opposed to sending a change proof for [`proof_start`, `requested_end`] where `proof_start` > `requested_start`. + +## Algorithm + +For each proof it receives, the sync client tracks the root hash of the revision associated with the proof's key-value pairs. +For example, it will store information that says something like, "I have all of the key-value pairs that +are in range [`start`, `end`] for the revision with root `root_hash`" for some keys `start` and `end`. +Note that `root_hash` is the root hash of the revision that the client is trying to sync to, not the +root hash of its own (incomplete) database. +Tracking the revision associated with each downloaded key range, as well as using data in its own +(incomplete) database, allows the client to figure out which key ranges are not up-to-date and need to be synced. +The hash of the incomplete database on a client is never sent anywhere because it does not represent a root hash of any revision. + +When the client is created, it is given the root hash of the revision to sync to. +When it starts syncing, it requests from a server a range proof for the entire database. +(To indicate that it wants no lower bound on the key range, the client doesn't provide a lower bound in the request. +To indicate that it wants no upper bound, the client doesn't provide an upper bound. +Thus, to request the entire database, the client omits both the lower and upper bounds in its request.) +The server replies with a range proof, which the client verifies. +If it's valid, the key-value pairs in the proof are written to the database. +If it's not, the client drops the proof and requests the proof from another server. + +A range proof sent by a server must return a continuous range of the key-value pairs, but may not +return the full range that was requested. +For example, a client might request all the key-value pairs in [`requested_start`, `requested_end`] +but only receive those in range [`requested_start`, `proof_end`] where `proof_end` < `requested_end`. +There might be too many key-value pairs to include in one message, or the server may be too busy to provide any more in its response. +Unless the database is very small, this means that the range proof the client receives in response to + its range proof request for the entire database will not contain all of the key-value pairs in the database. + +If a client requests a range proof for range [`requested_start`, `requested_end`] but only receives +a range proof for [`requested_start`, `proof_end`] where `proof_end` < `requested_end` +it recognizes that it must still fetch all of the keys in [`proof_end`, `requested_end`]. +It repeatedly requests range proofs for chunks of the remaining key range until it has all of the +key-value pairs in [`requested_start`, `requested_end`]. +The client may split the remaining key range into chunks and fetch chunks of key-value pairs in parallel, possibly even from different servers. + +Additional commits to the database may occur while the client is syncing. +The sync client can be notified that the root hash of the database it's trying to sync to has changed. +Detecting that the root hash to sync to has changed is done outside this package. +For example, if the database is being used to store blockchain state then the sync client would be +notified when a new block is accepted because that implies a commit to the database. +If this occurs, the key-value pairs the client has learned about via range proofs may no longer be up-to-date. + +We use change proofs as an optimization to correct the out of date key-value pairs. +When the sync client is notified that the root hash to sync to has changed, it requests a change proof +from a server for a given key range. +For example, if a client has the key-value pairs in range [`start`, `end`] that were in the database +when it had `root_hash`, then it will request a change proof that provides all of the key-value changes +in range [`start`, `end`] from the database version with root hash `root_hash` to the database version with root hash `new_root_hash`. +The client verifies the change proof, and if it's valid, it applies the changes to its database. +If it's not, the client drops the proof and requests the proof from another server. + +A server needs to have history in order to serve a change proof. +Namely, it needs to know all of the database changes between two roots. +If the server does not have sufficient history to generate a change proof, it will send a range proof for +the requested range at revision `new_root_hash` instead. +The client will verify and apply the range proof. (Note that change proofs are just an optimization for bandwidth and speed. +A range proof for a given key range and revision has the same information as a change proof from +`old_root_hash` to `new_root_hash` for the key range, assuming the client has the key-value pairs +for the key range at the revision with `old_root_hash`.) +Change proofs, like range proofs, may not contain all of the key-value pairs in the requested range. +This is OK because as mentioned above, the client tracks the root hash associated with each range of +key-value pairs it has, so it knows which key-value pairs are out of date. +Similar to range proofs, if a client requests the changes in range [`requested_start`, `requested_end`], +but the server replies with all of the changes in [`requested_start`, `proof_end`] for some `proof_end` < `requested_end`, +the client will repeatedly request change proofs until it gets remaining key-value pairs (namely in [`proof_end`, `requested_end`]). + +Eventually, by repeatedly requesting, receiving, verifying and applying range and change proofs, +the client will have all of the key-value pairs in the database. +At this point, it's synced. + +## Diagram + + +Assuming you have `Root Hash` `r1` which has many keys, some of which are k25, k50, k75, +approximately 25%, 50%, and 75% of the way into the sorted set of keys, respectively, +this diagram shows an example flow from client to server: + +```mermaid +sequenceDiagram + box Client/Server + participant Server + participant Client + end + box New Revision Notifier + participant Notifier + end + + Note right of Client: Normal sync flow + Notifier->>Client: CurrentRoot(r1) + Client->>Server: RangeProofRequest(r1, all) + Server->>Client: RangeProofResponse(r1, ..k25) + Client->>Server: RangeProofRequest(r1, k25..) + Server->>Client: RangeProofResponse(r1, k25..k75) + Notifier-)Client: NewRootHash(r2) + Client->>Server: ChangeProofRequest(r1, r2, 0..k75) + Server->>Client: ChangeProofResponse(r1, r2, 0..k50) + Client->>Server: ChangeProofRequest(r1, r2, k50..k75) + Server->>Client: ChangeProofResponse(r1, r2, k50..k75) + Note right of Client: client is @r2 through (..k75) + Client->>Server: RangeProofRequest(r2, k75..) + Server->>Client: RangeProofResponse(r2, k75..k100) +``` + +## TODOs + +- [ ] Handle errors on proof requests.
