This commit closes the loop by deleting every remaining `//go:build grpc` file under node/, removing the dual-build plumbing entirely. ZAP is the only wire protocol; there is no `-tags=grpc` opt-in. Per the "one and only one way to do everything" mandate, the backwards-compat scaffolding (gRPC adapters, protoc stubs, connect-go example handlers, OTLP gRPC exporter, x/sync gRPC sync engine, keystore-over-gRPC client/server, rpcwarp gRPC signer, gRPC alias reader) is removed forward-only — no aliases, no deprecation period. Deletions (84 files): - proto/pb/{aliasreader,http,io,keystore,message,messenger,net,p2p, platformvm,rpcdb,sdk,sender,sharedmemory,signer,sync, validatorstate,vm,warp}/ — protoc stubs (entire tree) - proto/{p2p,platformvm,sync,vm}/*_grpc.go — gRPC type re-exports - db/rpcdb/{grpc_server,grpc_client,grpc_test}.go — rpcdb gRPC adapter - service/keystore/rpckeystore/ — keystore-over-gRPC (dead consumer) - x/sync/ — entire merkledb sync engine (100% gRPC-tagged) - internal/ids/rpcaliasreader/ — gRPC alias reader (dead consumer) - connectproto/ — connect-go XSVM ping handler scaffolding - vms/platformvm/warp/rpcwarp/{client,server}.go — gRPC warp signer - vms/platformvm/network/warp.go — protobuf-based warp justification handler (warp_zap.go retains the no-op verifier consumers expect) - vms/components/message/message_grpc.go + message_test.go - vms/example/xsvm/api/ping.go + vm_http_grpc.go + cmd/{run,xsvm}/ - wallet/network/primary/examples/sign-l1-validator-* (5 dead example main packages) - trace/{exporter_grpc,exporter_type,exporter_type_test,noop,tracer}.go (OTLP gRPC exporter + duplicate Tracer types — trace_zap.go has the canonical Tracer interface + no-op tracer) - message/bft_grpc.go (Simplex BFT wrapper) Edits (9 files): every surviving `_zap.go` drops its `//go:build !grpc` constraint (the files are unconditional now) and drops stale "ZAP version" / "ZAP mode" inline comments. Doc updates: - LLM.md ZAP Transport section: remove the `-tags=grpc` opt-in language. Replace with "ZAP is the only wire protocol... there is one and only one way". Update Latest Tag to v1.26.31. Update the rpcdb topology section to reflect single-adapter state. go.mod: connectrpc.com/connect, connectrpc.com/grpcreflect, otlptracegrpc moved out of direct deps. google.golang.org/grpc + protobuf demoted to indirect (still pulled transitively via luxfi/dex). Verified: - `go build ./...` (default, no tags) clean - `go test ./db/rpcdb/... ./trace/... ./message/... ./vms/rpcchainvm/... ./vms/components/message/... ./vms/platformvm/network/... ./vms/example/xsvm/... ./service/keystore/... ./proto/...` clean - `grep -rln '//go:build grpc' --include='*.go' node/` returns zero - `grep -rln '//go:build !grpc' --include='*.go' node/` returns zero - `grep -rln 'google.golang.org/grpc' --include='*.go' node/` returns zero (only transitive deps remain in go.sum) Pre-existing TestGraniteNetworkIDConfiguration failure in tests/ is unrelated — fails on the parent commit too (verified via stash). 哗xs tree ae55e5b5dd8339759f00e5dca678d5d4f6229623 parent 74b3475b75a2c4635e322435118cf80ff29c0d69 author Hanzo AI 1778976691 -0700 committer Hanzo AI 1778976691 -0700 rpcchainvm: zap-native only — delete every grpc-tagged path The VM<->Node RPC plane is ZAP. Period. The dual-transport apparatus (TransportConfig, NewFactoryWithTransport, Transport enum, UsesGRPC/UsesZAP, factory_grpc.go vs factory_zap.go stub) only existed to switch between ZAP and a grpc fallback that the codebase no longer ships. Per the "one and only one way" / "no backwards compatibility, only forwards perfection" mandate, the choice is collapsed and every grpc-tagged file under vms/rpcchainvm is removed. Deletions (36 files, ~4.3K lines): - factory_grpc.go, factory_zap.go, transport.go (the dual-transport routing + Transport enum) - vm.go, vm_client.go, vm_server.go, block_adapter.go, *_test.go (the grpc VMClient/Server + tests) - gruntime/, gvalidators/, messenger/, rpchttp/ (every subdir was 100% //go:build grpc) - sender/client.go, sender/server.go (grpc Sender wire impls; sender.go + zap_client.go + zap_server.go stay) - runtime/subprocess/runtime_grpc.go (the gRPC subprocess.Bootstrap; runtime_zap.go is now the only Bootstrap) - vms/platformvm/warp/rpcwarp/signer_test.go (orphan grpc test that relied on the deleted proto/pb/warp) Edits: - vms/rpcchainvm/factory.go: drop transportConfig field, drop NewFactoryWithTransport, drop the UsesGRPC() routing — there is one path, it constructs a ZAP listener, dials the subprocess over ZAP, returns the ZAP client. No branching. - vms/rpcchainvm/runtime/subprocess/runtime_zap.go: drop the `//go:build !grpc` tag (no grpc counterpart to gate against anymore) and rewrite the Bootstrap doc-comment. go mod tidy result: - direct dep `google.golang.org/grpc` demoted to `// indirect` (still pulled transitively via luxfi/dex) - direct dep `github.com/grpc-ecosystem/go-grpc-prometheus` removed entirely Verified: - `go build ./...` (default, no tags) clean - `go test -count=1 ./vms/rpcchainvm/...` clean - grep -rln 'google.golang.org/grpc' --include='*.go' under node/ returns zero (the only google.golang.org/grpc strings left are in go.mod/go.sum/README/RELEASES/ci.yml/proto/Dockerfile) - grep 'grpc.Dial|NewServer|NewClient' in rpcchainvm returns zero ` 9*xStree 38fefbe9aee5057825824c91d73714eb50efe3f3 parent 8aa002d245d01a8c307085b06b718412ac8617ed author hanzo-dev 1778975261 -0700 committer hanzo-dev 1778975261 -0700 .gitignore + docs: drop stale db* rule; refresh Latest Tag to v1.26.28 The bare `db*` .gitignore rule was overly broad — it matched the canonical node/db/rpcdb/ source directory (consolidated in v1.26.28). Previous PRs needed `git add -f` to land files there. No code references in-repo ./db/ runtime path; runtime DB lives under ~/.lux/ per the canonical operator convention. LLM.md + CLAUDE.md updated to reflect actual current main tag.

Part B — fold node/internal/database/rpcdb into node/db/rpcdb: Both packages were grpc-tagged gRPC adapters against the same rpcdbpb.DatabaseClient/Server. The internal one (db_client.go/db_server.go) predated the Layer A/B/C decomplect; the db/rpcdb one (grpc_server.go + zap_server.go) is the canonical Layer-C home with one Service and one transport adapter per wire format. New grpc_client.go in db/rpcdb mirrors the deleted internal db_client.go using the same Layer-B Error codes (via codeToErr), behind the `grpc` build tag — symmetric with grpc_server.go. Updated service/keystore/rpckeystore/client.go to import the canonical db/rpcdb.NewGRPCClient instead of internal/database/rpcdb.NewClient. internal/database/rpcdb/ deleted in its entirety. One canonical rpcdb home; no dual-shim, no deprecation period. Default-tag build is clean. The pre-existing -tags=grpc breakage in node/proto/pb/rpcdb (protoc-generated stub) is orthogonal and was already broken on main before this change — it affects the legacy and the new adapter identically because both reference the same rpcdbpb symbols.SHxtree 9f218eb7c149e16418f4ef6d51820aacba049756 parent b3575106d43086198db7b87da12084ad9ed57b69 author Hanzo Dev 1778974195 -0700 committer GitHub 1778974195 -0700 deps: luxfi/api v1.0.10 -> v1.0.11 (#108) Picks up ConsensusInfo.Corona -> ConsensusInfo.Corona rename so the service_test.go typecheck (TestGetNodeVersionConsensusRoundtrip) compiles.

Mirrors the proto/zap/{vm,p2p,sync,platformvm} pattern. * New proto/rpcdb/rpcdb_zap.go (build tag !grpc) — full ZAP-native DatabaseClient + DatabaseServer + Register hook, implements database.Database against any Transport. The host's underlying DB is luxfi/database (zapdb in production); the protocol shape is identical regardless of which engine the host runs. * Renamed the existing rpcdb.go to rpcdb_grpc.go so the two variants are mutually exclusive: build with no tag (ZAP default) or with `-tags=grpc` (protobuf path), never both. examples/multi-network/multi-network-poc.go: drop duplicate-key map entry where Q-Chain was illustrated as a separate network — Q-Chain shares the primary network ID per LP-134, see comments on MainnetID entry. Net effect: full default build is ZAP-only PQ-secure-channel-aware, RPC over a Z-Wing-encrypted ZAP transport, no gRPC/protobuf in the critical path.

Plus a clarifying comment on the upgrade-config switch noting which network IDs are permitted to override their upgrade schedule (any non-well-known ID, including DevnetID/UnitTestID and any genuinely custom user-defined network ID).

The legacy LP-9701 in-RNS-link crypto (rns_link.go) stays in place during the transition; new p2p paths should layer ZWingDialer over the EndpointDialer instead of relying on LP-9701's inline encryption. Adds: network/dialer/zwing_dialer.go ZWingDialer + ZWingListener network/dialer/zwing_dialer_test.go 5 e2e tests covering: - missing-identity rejection (dialer + listener) - real TCP listener + Z-Wing handshake + payload round trip - Wrap() over an arbitrary net.Conn (net.Pipe stand-in for RNS) - identity mismatch (MitM defence) - DialEndpoint over an Endpoint (works for IP, hostname, future RNS) Bumps: github.com/luxfi/zwing v0.5.2 (full FIPS 204 PQ stack, cross-language wire-byte interop with Rust/Py/TS) github.com/luxfi/api v1.0.10 (NewListener seam used by zwing.ListenZAP) luxd-side wiring (node.go construction with a loaded LocalIdentity) is the next follow-up; this commit lands the seam without behavioural changes to the existing dialer interface. pdO1xtree 875164c38a8407b3fde901ac4e39d9a258025a5c parent 00fa0653a1993db1408a6b505028039e507f7df2 author Hanzo AI 1778048544 -0700 committer Hanzo AI 1778048544 -0700 canonical: rip vestigial protobuf — ZAP is the only wire protocol Lux's primary wire protocol is ZAP (Zero-Copy App Proto).

Pin published versions: - github.com/luxfi/utxo v0.2.7 (adds InitRuntime forwarder) - github.com/luxfi/chains/{aivm,bridgevm,dexvm,graphvm,identityvm, keyvm,oraclevm,quantumvm,relayvm,thresholdvm,zkvm} v0.1.0 No replace directives — every dependency resolves to a published tag. 1U?x tree 12e8bcfecd0f377d6b5aed7656117a43ed3b2d1b parent 8de1b78ed8b8c2d0d036ebdfac7d1f80d1f9b2c7 author Hanzo AI 1776088952 -0700 committer Hanzo AI 1776088952 -0700 fix: add main/main.go entry point for luxd binary Restores the missing entry point that .goreleaser.yml, Makefile, and scripts/build.sh all expect at ./main. Without this file, the release pipeline fails with 'couldn't find main file: stat main: no such file or directory'. The main wires: config.BuildFlagSet → config.BuildViper → config.GetNodeConfig → log.NewFactoryWithConfig → ulimit.Set → node.New(*node.Config, log.Factory, log.Logger) → n.Dispatch() with SIGINT/SIGTERM handling → exit n.ExitCode() --version short-circuits to print version.CurrentApp.String() (e.g. 'luxd/1.23.25'). Not using the orphan app/ package (app.New takes nodeconfig.Config which is a parallel type definition not produced by config.GetNodeConfig). The app/ package can be migrated separately or removed.

Delete the in-tree duplicate at node/vms/components/lux/ and import the standalone luxfi/utxo package with a 'lux' alias so existing call-sites (lux.UTXO, lux.TransferableInput, etc.) remain unchanged in consumers. Files changed: 167 imports rewritten, 2 directories deleted. Build still green on the whole tree except pre-existing examples/multi-network QChainMainnetID issue (unrelated). Next: rename luxfi/utxo/luxmock → utxomock for full brand-neutrality; that is a separate PR since it requires touching all consumer alias names.

Stop accepting new connections 2. Finish processing current requests 3. Save state to disk 4. Close database connections 5. Exit cleanly ## Backup and Recovery ### Backup Critical Files ```bash # Backup staking keys (CRITICAL) cp -r ~/.luxd/staking ~/luxd-backup/ # Backup database (optional, can resync) cp -r ~/.luxd/db ~/luxd-backup/ # Backup configs cp -r ~/.luxd/configs ~/luxd-backup/ ``` ### Restore from Backup ```bash # Stop node systemctl stop luxd # Restore files cp -r ~/luxd-backup/staking ~/.luxd/ cp -r ~/luxd-backup/db ~/.luxd/ cp -r ~/luxd-backup/configs ~/.luxd/ # Start node systemctl start luxd ``` ## Common Issues ### Node Not Connecting to Peers 1. Check firewall rules allow ports 9630-9631 2. Verify correct network-id 3. Ensure public IP is reachable 4. Check bootstrap nodes are online ### High Memory Usage 1. Reduce cache sizes in config 2. Enable database pruning 3. Limit peer connections 4. Use PebbleDB instead of BadgerDB ### Slow Synchronization 1. Ensure sufficient bandwidth 2. Use SSD for database storage 3.

Features multiple consensus engines (Chain, DAG, PQ), EVM compatibility, and a multi-chain architecture with specialized capabilities. **Key Context:** - Original Lux Network node — NOT a fork - Network ID: 96369 (Lux Mainnet), 96368 (Testnet), 96370 (Devnet) - Go Version: 1.26.1+ - Database: ZapDB (primary, default) ## Essential Commands ### Building ```bash # Build node binary ./scripts/run_task.sh build # Output: ./build/luxd # Build specific components go build -o luxd ./app ``` ### Testing ```bash # Run all tests go test ./... -count=1 # Run specific package go test ./vms/platformvm/state -count=1 # With race detection go test -race ./... ``` ### Code Generation ```bash # Generate mocks go generate ./... # Regenerate protobuf ./scripts/run_task.sh generate-protobuf ``` ### Running ```bash # Mainnet ./build/luxd # Testnet ./build/luxd --network-id=testnet # Local network lux network start ``` ## Architecture ### Multi-Chain Design Primary network (P/X/C) uses Quasar consensus via `luxfi/consensus`. All new native chains use Quasar (BLS + Corona + ML-DSA). No snow/snowball. | Chain | Purpose | VM | Consensus | |-------|---------|-----|-----------| | **P-Chain** | Staking, validators, L1 validators | PlatformVM | Quasar | | **X-Chain** | UTXO-based asset exchange | XVM | Quasar | | **C-Chain** | EVM smart contracts | EVM | Quasar | | **A-Chain** | AI inference, model registry | AIVM | Quasar | | **B-Chain** | Cross-chain bridge operations | BridgeVM | Quasar | | **D-Chain** | DEX (order book, perpetuals) | DexVM | Quasar | | **G-Chain** | On-chain graph database | GraphVM | Quasar | | **I-Chain** | Decentralized identity (DID/VC) | IdentityVM | Quasar | | **K-Chain** | Post-quantum key management | KeyVM | Quasar | | **M-Chain** | Threshold signing (MPC) | ThresholdVM | Quasar | | **O-Chain** | Oracle price feeds | OracleVM | Quasar | | **Q-Chain** | Post-quantum consensus coordination | QuantumVM | Quasar | | **R-Chain** | Cross-chain message relay | RelayVM | Quasar | | **S-Chain** | Service node coordination | ServiceNodeVM | Quasar | | **T-Chain** | Cross-chain teleport (bridge+relay+oracle) | TeleportVM | Quasar | | **Z-Chain** | Zero-knowledge proofs (FHE) | ZKVM | Quasar | ### Consensus Layer Located in `/consensus/` (separate package `{`): - **Quasar**: Production consensus -- BLS12-381 + Corona (lattice) + ML-DSA-65 (FIPS 204) - **Chain Engine**: Linear blockchain consensus (Nova sub-protocol) - **DAG Engine**: Directed acyclic graph for parallel processing (Nebula sub-protocol) - **PQ Engine**: Post-quantum finality layer Sub-protocols: Photon (sampling) -> Wave (voting) -> Focus (confidence) -> Ray/Field (finality) ### Virtual Machines Located in `/vms/`: - **platformvm**: Staking, validation, network management - **xvm**: Asset transfers, UTXO model - **dexvm**: DEX with order book, perpetuals, AMM - **thresholdvm**: Threshold MPC and FHE for confidential computing - **quantumvm**: PQ consensus coordination (ML-DSA, Corona) - **identityvm**: Decentralized identity (DID, verifiable credentials) - **keyvm**: Post-quantum key management (ML-KEM, ML-DSA) - **bridgevm**: Cross-chain bridge with MPC attestation - **oraclevm**: Decentralized oracle network - **aivm**: AI inference verification - **graphvm**: On-chain graph database - **relayvm**: Cross-chain message relay - **servicenodevm**: Service node epoch management - **teleportvm**: Unified bridge+relay+oracle - **zkvm**: Zero-knowledge proof verification - **proposervm**: Block proposer wrapper VM ### Key Interfaces **p2p.Sender** (from `github.com/luxfi/p2p`): ```go type Sender interface { SendRequest(ctx context.Context, nodeIDs set.Set[ids.NodeID], requestID uint32, request []byte) error SendResponse(ctx context.Context, nodeID ids.NodeID, requestID uint32, response []byte) error SendError(ctx context.Context, nodeID ids.NodeID, requestID uint32, errorCode int32, errorMessage string) error SendGossip(ctx context.Context, config SendConfig, msg []byte) error } ``` **Keychain Interfaces** (from `github.com/luxfi/keychain`): ```go type Signer interface { SignHash([]byte) ([]byte, error) Sign([]byte) ([]byte, error) Address() ids.ShortID } type Keychain interface { Get(addr ids.ShortID) (Signer, bool) Addresses() set.Set[ids.ShortID]L } ``` ## Package Dependencies ### CRITICAL: Use Lux packages only - ✅ `9` - ✅ `github.com/luxfi/geth` (NOT go-ethereum) - ✅ `{` - ✅ `github.com/luxfi/keychain` - ✅ `github.com/luxfi/ledger` - ✅ `github.com/luxfi/lattice` (FHE) - ❌ `github.com/luxfi/*` legacy upstream forks - ❌ `github.com/ethereum/go-ethereum` ### Import Aliasing Avoid conflicts with consensus packag%es: ```go import ( platformblock N block" consensusblock zengine/chain" ) ``` ## Token Denomination LUX uses **6 decimals** (microLUX base unit) on P-Chain/X-Chain: | Unit | Value | |------|-------| | µLUX (MicroLux) | 1 (base) | | mLUX (MilliLux) | 1,000 | | LUX | 1,000,000 | | TLUX (TeraLux) | 10^18 | **Supply Cap**: 2 trillion LUX (2 × 10^18 µLUX) C-Chain uses standard EVM 18 decimals (Wei). See `utils/units/lux.go` for constants. ## Key Technical Decisions ### Genesis Architecture ``` github.com/luxfi/genesis (JSON config) → github.com/luxfi( (type conversion) ``` - Genesis package has no node dependencies - Builder package handles type conversions (string → ids.NodeID, uint64 → time.Duration) ### CGO Dependencies These require CGO for full functionality (graceful fallback when disabled): - `consensus/quasar` - GPU NTT acceleration - `vms/thresholdvm/fhe` - GPU FHE operations - `x/blockdb` - zstd compression ### FHE (Fully Homomorphic Encryption) Located in `vms/thresholdvm/fhe/`: - Uses `github.com/luxfi/lattice/multiparty` for DKG - Lattice-based cryptography only (no fallbacks) - Threshold decryption via Warp messaging **Precompile Addresses:** | Precompile | Address | |------------|---------| | Fheos | `0x0200000000000000000000000000000000000080` | | ACL | `0x0200000000000000000000000000000000000081` | | InputVerifier | `0x0200000000000000000000000000000000000082` | | Gateway | `0x0200000000000000000000000000000000000083` | ### ZAP Transport (Zero-Copy App Proto) ZAP is the default high-performance binary wire protocol for VM<->Node communication. gRPC support is available via build tag for testing/compatibility. **Build Tags:** ```bash go build  # ZAP only (default, production) go build -tags=grpc # gRPC support (for testing/compatibility) ``` **Key Packages:** - `github.com/luxfi/api/zap` - Core wire protocol and message types - `github.com/luxfi/vm/rpc/sender` - p2p.Sender over ZAP/gRPC - `vms/rpcchainvm/sender/` - Node-side sender implementation - `vms/platformvm/warp/zwarp/` - ZAP-based warp signing client/server **Wire Protocol Format:** ``` [4 bytes: length][1 byte: message type][payload...] ``` **Performance Benefits:** - Zero-copy serialization (buffer pooling via sync.Pool) - ~5-10x faster serialization than protobuf - ~2-3x lower latency (no HTTP/2 overhead) - ~30-50% CPU reduction on hot paths **Sender Usage:** ```go // ZAP transport (default) s := sender.ZAP(zapConn) // gRPC transport (requires -tags=grpc build) s := sender.GRPC(senderpb.NewSenderClient(grpcConn)) ``` **Warp over ZAP:** The `zwarp` package implements warp signing via ZAP: ```go // Client implements warp.Signer over ZAP client := zwarp.NewClient(zapConn) sig, err := client.Sign(unsignedMsg) // BatchSign for HFT optimization sigs, errs := client.BatchSign(messages) ``` ## RNS Transport (Reticulum Network Stack) The node supports RNS as an alternative transport layer alongside TCP/IP, enabling mesh networking, LoRa connectivity, and offline-first validator operation. **Specification**: [LP-9701](../lps/LPs/lp-9701-reticulum-network-stack.md) ### Endpoint Types The `net/endpoints` package supports three addressing modes: ```go // IP address endpoint :=/anetip.MustParseAddrPort("203.0.113.50:9631")) // Hostname (DNS resolved) endpoint, _ := endpoints.NewHostnameEndpoint("validator.example.com", 9631) // RNS destination (mesh/LoRa) endpoint, _ := endpoints.NewRNSEndpointFromHex("rns://a5f72c3d4e5f60718293a4b5c6d7e8f9") ``` ### Key Files | File | Purpose | |------|---------| | `net/endpoints/endpoint.go` | Unified endpoint abstraction (IP, hostname, RNS) | | `network/dialer/rns_transport.go` | RNS transport implementation | | `network/dialer/rns_identity.go` | Classical identity (Ed25519 + X25519) | | `network/dialer/rns_identity_pq.go` | Hybrid PQ identity (+ ML-DSA + ML-KEM) | | `network/dialer/rns_link.go` | Encrypted link protocol with PQ support | | `network/dialer/rns_announce.go` | Destination discovery and announcements | ### Configuration ```yaml # ~/.lux/config.yaml rns: enabled: true configPath: ~/.lux/reticulum announceInterval: 5m interfaces: - AutoInterface - TCPClientInterface linkTimeout: 30s postQuantum: true  # Enable hybrid PQ mode requirePostQuantum: false # Allow classical-only peers ``` ## Post-Quantum Cryptography (Hybrid Mode) RNS transport supports hybrid post-quantum cryptography combining classical algorithms with NIST-standardized post-quantum primitives (TLS 1.3-like approach). ### Cryptographic Suite | Purpose | Classical | Post-Quantum | Security | |---------|-----------|--------------|----------| | Identity Signing | Ed25519 | ML-DSA-65 | NIST Level 3 | | Key Exchange | X25519 | ML-KEM-768 | NIST Level 3 | | Session Encryption | AES-256-GCM | - | 256-bit | | Key Derivation | HKDF-SHA256 | - | - | ### Forward Secrecy - **Ephemeral Keys**: Fresh X25519 + ML-KEM keypairs generated per session - **Key Destruction**: Ephemeral private keys zeroed after handshake - **Hybrid Derivation**: `combined_secret = X25519_shared || ML_KEM_shared` - **Defense-in-Depth**: Secure if either algorithm remains unbroken ### Wire Format Sizes | Component | Classical | Hybrid | Delta | |-----------|-----------|--------|-------| | Public Identity | 64 bytes | ~3.2 KB | +3.1 KB | | Signature | 64 bytes | ~2.5 KB | +2.4 KB | | Key Exchange | 64 bytes | ~1.2 KB | +1.1 KB | | Handshake Total | ~256 bytes | ~7.5 KB | +7.2 KB | ### Backward Compatibility  - **Capability Exchange**: Handshake advertises PQ support - **Graceful Fallback**: Falls back to classical if peer lacks PQ - **Mixed Networks**: PQ and classical validators coexist - **Policy Enforcement**: `requirePostQuantum: true` rejects classical peers ### Testing PQ Forward Secrecy ```bash # Run hybrid PQ tests go test -v -run "TestHybrid" ./node/network/dialer/... -count=1 # Key tests: # - TestHybridIdentity_SignVerify (ML-DSA-65 signatures) # - TestHybridIdentity_Encapsulate_Decapsulate (ML-KEM-768) # - TestHybridRNSLink_Handshake (full hybrid handshake) # - TestHybridRNSLink_ForwardSecrecy (ephemeral key destruction) # - TestHybridToClassical_Fallback (backward compatibility) ``` ## Common Gotchas ### 1. 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 contaip" 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. ### 8. `vms/components/lux` vs `luxfi/utxo` (parallel UTXO types) The `components/lux` package contains a parallel `lux.UTXO`/`lux.TransferableInput` type tree alongside `github.com/luxfi/utxo`. External consumers (e.g. `~/work/liquidity/network-bootstrap/fund.go`) need to import the `vms/components/lux` variant to interop with PlatformVM/AVM tx builders — `luxfi/utxo` types alone are not accepted by the X→P export path. This is a known anomaly pending #58 follow-up consolidation; do NOT collapse the two packages without that migration. ## 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, receivesa the full ancestor chain, and processes blocks in order, advancing the P-chain height. **Note**:(`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. ZAP CreateHandlers for VM HTTP Endpoints **Problem**: C-chain and D-chain RPC endpoints returning 404 despite VMs running. **Cause**: The `zap.Client` in `vms/rpcchainvm/zap/client.go` did not implement the `CreateHandlers` interface. The node checks for this interface to register HTTP handlers (like `/rpc`, `/ws`) with the HTTP server. **Solution**: Added `CreateHandlers` method to `zap.Client` that: 1. Sends `MsgCreateHandlers` via ZAP wire protocol to the VM 2. Receives `CreateHandlersResponse` with list of handlers (prefix + server address) 3. Creates `httputil.NewSingleHostReverseProxy` for each handler 4. Returns `map[string]http.Handler` for registration **File Modified**: `vms/rpcchainvm/zap/client.go` **Verification**: ```bash curl -s -X POST -H "Content-Type: application/json" \ -d '{"jsonrpc":"2.0","method":"eth_chainId","params":[],"id":1}' \ http://localhost:9640/ext/bc/C/rpc # Returns: {"jsonrpc":"2.0","id":1,"result":"0x17870"} ``` ### 9. 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 h 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 s.validators.NumNets() != 0 { // skip re-adding them here return nil } ``` **After**: ```go if s.validators.NumNets() != 0 { log.Info("initValidatorSets: validator manager not empty, will update with BLS keys") } // Continue to add validators with proper BLS keys ``` **Verification**: ```bash curl -s http://localhost:9650/ext/health | jq '.checks.bls' # Should show: "message": "node has the correct BLS key" ``` ## Benchmark Results (Single Node) Testing conducted on a single Lux validator node (testnet mode, macOS): | Metric | Result | |--------|--------| | Sustained TPS | 1,091 TPS (60s benchmark) | | Peak TPS | 1,094 TPS (5 workers) | | Query Performance | 840 queries/sec | | Query Latency | 17.67ms avg | | Optimal Concurrency | 5 workers | | Total Transactions | 65,497 txs/min | **Concurrency Scaling:** | Workers | TPS | |---------|-----| | 1 | 438 | | 5 | 1,094 (optimal) | | 10 | 684 | | 20 | 521 | **Key Findings:** - Single node achieves ~1,100 TPS sustained with optimal concurrency - Higher concurrency (>5 workers) decreases TPS due to nonce contention - Query latency is consistent at ~18ms - Testnet mode uses K=20 Lux consensus (vs K=1 dev mode) **Benchmark Command:** ```bash cd ~/work/lux/benchmarks LUX_ENDPOINT="http://localhost:9640/ext/bc/C/rpc" \ PRIVATE_KEY="" \ ./bin/bench tps --chains=luxE --duration=60s --concurrency=5 ``` --- *Last Updated*:
