+# Lux Precompiled Contracts
+
+This directory contains all precompiled contracts (precompiles) for the Lux blockchain ecosystem. Precompiles are special smart contracts implemented natively in the node software for performance-critical operations that would be too expensive or slow to implement in Solidity.
+
+## Overview
+
+Precompiles are located at deterministic addresses starting from `0x0200000000000000000000000000000000000000`. They provide optimized implementations for cryptographic operations, cross-chain messaging, and chain configuration.

+## Implementation Structure
+
+Each precompile directory contains:
+
+```
+<precompile-name>/
+├── module.go          # Precompile module registration
+├── contract.go        # Core precompile implementation
+├── contract_test.go   # Go test suite
+├── config.go          # Configuration structures (if applicable)
+├── config_test.go     # Configuration tests
+├── I<Name>.sol        # Solidity interface
+├── contract.abi       # ABI definition (if applicable)
+└── README.md          # Detailed documentation
+```
+
+## Development Guidelines
+
+### Adding a New Precompile
+
+1. **Choose an Address**: Select next available address in sequence
+2. **Create Directory**: `mkdir -p src/precompiles/<name>`
+3. **Implement Interface**: Must implement `StatefulPrecompiledContract`
+4. **Write Tests**: Minimum 80% code coverage
+5. **Create Solidity Interface**: Include full documentation
+6. **Write LP**: Document specification in lps/LPs/
+7. **Update This README**: Add to address table and category
+
+### Required Interfaces
+
+All precompiles must implement:
+
+```go
+type StatefulPrecompiledContract interface {
+    // Address returns the precompile address
+    Address() common.Address
+    
+    // RequiredGas calculates gas cost for input
+    RequiredGas(input []byte) uint64
+    
+    // Run executes the precompile logic
+    Run(
+        accessibleState AccessibleState,
+        caller common.Address,
+        addr common.Address,
+        input []byte,
+        suppliedGas uint64,
+        readOnly bool,
+    ) ([]byte, uint64, error)
+}
+```
+
+### Module Registration
+
+Each precompile must provide a module for registration:
+
+```go
+type module struct {
+    address  common.Address
+    contract StatefulPrecompiledContract
+}
+
+func (m *module) Address() common.Address { 
+    return m.address 
+}
+
+func (m *module) Contract() StatefulPrecompiledContract { 
+    return m.contract 
+}
+```
+
+### Gas Calculation Guidelines
+
+Gas costs should reflect:
+1. **Computational complexity**: Higher for crypto operations
+2. **Memory usage**: Larger for big inputs/outputs
+3. **State access**: More for state reads/writes
+4. **Benchmarks**: Based on real performance measurements
+
+Example gas formulas:
+- **Simple state read**: ~2,000 gas
+- **Cryptographic verification**: 50,000 - 500,000 gas
+- **Per-byte processing**: 10 - 50 gas/byte
+- **State writes**: ~20,000 gas per slot
+
+## Testing Requirements
+
+All precompiles must have:
+
+1. **Unit Tests** (`contract_test.go`):
+   - Valid input cases
+   - Invalid input cases
+   - Edge cases
+   - Gas calculation verification
+
+2. **Solidity Tests**:
+   - Interface usage examples
+   - Integration with other contracts
+   - Gas benchmarks
+
+3. **Benchmarks**:
+   - Performance measurements
+   - Gas cost validation
+   - Comparison with pure Solidity implementation
+
+## Security Considerations
+
+### Input Validation
+- **Always** validate input length before parsing
+- Check for buffer overflows
+- Validate all parameters against constraints
+
+### Gas Limits
+- Ensure gas costs prevent DoS attacks
+- Test with maximum-size inputs
+- Verify gas calculations don't overflow
+
+### State Access
+- Only modify state in non-read-only calls
+- Validate caller permissions for privileged operations
+- Ensure atomic state updates
+
+### Cryptographic Operations
+- Use constant-time implementations when possible
+- Validate all cryptographic inputs
+- Check signature/key sizes match expected values
+- Test against known attack vectors
+
+## Performance Benchmarks
+
+Performance targets on Apple M1 (reference hardware):
+
+| Operation | Target | Current |
+|-----------|--------|---------|
+| ML-DSA-65 Verify | < 150μs | ~108μs ✓ |
+| SLH-DSA-192s Verify | < 20ms | ~15ms ✓ |
+| BLS Signature Verify | < 2ms | ~1.5ms ✓ |
+| State Read | < 5μs | ~2μs ✓ |
+| State Write | < 10μs | ~5μs ✓ |
+
+## Documentation Standards
+
+Each precompile must document:
+
+1. **Purpose and Use Cases**: Why it exists, when to use it
+2. **Input/Output Format**: Exact byte layouts with examples
+3. **Gas Costs**: Formula and examples
+4. **Error Conditions**: All possible failure modes
+5. **Security Considerations**: Potential vulnerabilities
+6. **Examples**: Both Go and Solidity usage

+# CGGMP21 Threshold Signature Precompile
+
+## Overview
+
+The CGGMP21 (Canetti-Gennaro-Goldfeder-Makriyannis-Peled 2021) precompile enables threshold ECDSA signature verification. CGGMP21 is the state-of-the-art threshold signature protocol with identifiable aborts and efficient key refresh.
+
+**Address**: `0x020000000000000000000000000000000000000D`
+
+## Features
+
+- **Threshold ECDSA**: Any t out of n parties can sign
+- **Identifiable Aborts**: Malicious parties can be detected
+- **Key Refresh**: Update shares without changing public key
+- **Standard ECDSA**: Compatible with Ethereum, Bitcoin, etc.
+- **MPC Custody**: Enterprise-grade multi-party custody
+
+## Algorithm
+
+CGGMP21 is a threshold signature scheme where:
+- **n** total parties hold shares of an ECDSA private key
+- Any **t** parties can collaborate to produce a valid signature
+- The signature is standard ECDSA (indistinguishable from single-party)
+- Malicious parties causing failures can be identified
+
+### Key Properties
+
+- **Identifiable Aborts**: Unlike GG20, can identify malicious parties
+- **Efficient Refresh**: Proactive security without downtime
+- **Non-Interactive DKG**: Efficient distributed key generation
+- **Presignature Support**: Precompute signatures for faster online phase
+
+## Specifications
+
+### Input Format
+
+Total size: **170 bytes** (minimum)
+
+| Offset | Size | Field | Description |
+|--------|------|-------|-------------|
+| 0-3 | 4 bytes | threshold | Minimum signers required (t) |
+| 4-7 | 4 bytes | totalSigners | Total number of parties (n) |
+| 8-72 | 65 bytes | publicKey | Aggregated ECDSA public key (uncompressed) |
+| 73-104 | 32 bytes | messageHash | Keccak256 hash of message |
+| 105-169 | 65 bytes | signature | ECDSA signature (r \|\| s \|\| v) |
+
+### Output Format
+
+**32 bytes**: Boolean result as uint256
+- `0x0000...0001` = Valid signature
+- `0x0000...0000` = Invalid signature
+
+### Gas Costs
+
+| Operation | Base Gas | Per-Signer Gas |
+|-----------|----------|----------------|
+| CGGMP21 Verify | 75,000 | 10,000 |
+
+**Examples**:
+- 2-of-3 threshold: 75,000 + (3 × 10,000) = **105,000 gas**
+- 3-of-5 threshold: 75,000 + (5 × 10,000) = **125,000 gas**
+- 5-of-7 threshold: 75,000 + (7 × 10,000) = **145,000 gas**
+- 10-of-15 threshold: 75,000 + (15 × 10,000) = **225,000 gas**
+
+## Usage Examples
+
+### Solidity - Threshold Wallet
+
+```solidity
+import "./ICGGMP21.sol";
+
+contract MultiSigWallet is CGGMP21Verifier {
+    bytes public thresholdPublicKey;
+    uint32 public threshold;
+    uint32 public totalSigners;
+
+    function executeWithThreshold(
+        address to,
+        uint256 value,
+        bytes calldata data,
+        bytes calldata signature
+    ) external {
+        bytes32 txHash = keccak256(abi.encodePacked(to, value, data, nonce));
+
+        verifyCGGMP21Signature(
+            threshold,
+            totalSigners,
+            thresholdPublicKey,
+            txHash,
+            signature
+        );
+
+        // Execute transaction
+        (bool success, ) = to.call{value: value}(data);
+        require(success, "Execution failed");
+    }
+}
+```
+
+### TypeScript (ethers.js)
+
+```typescript
+const CGGMP21 = new ethers.Contract(
+    '0x020000000000000000000000000000000000000D',
+    [
+        'function verify(uint32,uint32,bytes,bytes32,bytes) view returns(bool)'
+    ],
+    provider
+);
+
+// Verify 3-of-5 threshold ECDSA signature
+const isValid = await CGGMP21.verify(
+    3,              // threshold
+    5,              // totalSigners
+    publicKey,      // 65 bytes uncompressed
+    messageHash,    // 32 bytes
+    signature       // 65 bytes ECDSA
+);
+```
+
+### Go - MPC Integration
+
+```go
+import (
+    "github.com/luxfi/mpc/pkg/protocol/cggmp21"
+)
+
+// Initialize CGGMP21 protocol
+protocol := cggmp21.NewProtocol()
+
+// Distributed key generation (3-of-5)
+keygenParty, err := protocol.KeyGen("party1", partyIDs, 3)
+config := keygenParty.Result()
+
+// Threshold signing
+signParty, err := protocol.Sign(config, signers, messageHash)
+signature := signParty.Result()
+
+// Verify on-chain via precompile
+```
+
+## Use Cases
+
+### 1. Multi-Party Custody
+
+```solidity
+contract InstitutionalCustody is CGGMP21Verifier {
+    // 5-of-7 threshold for institutional custody
+    uint32 constant THRESHOLD = 5;
+    uint32 constant TOTAL_SIGNERS = 7;
+
+    function transferAssets(
+        address token,
+        address to,
+        uint256 amount,
+        bytes calldata thresholdSig
+    ) external {
+        bytes32 txHash = keccak256(abi.encodePacked(token, to, amount));
+
+        verifyCGGMP21Signature(
+            THRESHOLD,
+            TOTAL_SIGNERS,
+            custodyPublicKey,
+            txHash,
+            thresholdSig
+        );
+
+        IERC20(token).transfer(to, amount);
+    }
+}
+```
+
+### 2. DAO Treasury Management
+
+```solidity
+contract DAOTreasury is CGGMP21Verifier {
+    // 7-of-10 DAO council
+    function executeDAODecision(
+        bytes32 proposalId,
+        bytes calldata executionData,
+        bytes calldata councilSignature
+    ) external {
+        verifyCGGMP21Signature(
+            DAO_THRESHOLD,
+            DAO_COUNCIL_SIZE,
+            daoPublicKey,
+            proposalId,
+            councilSignature
+        );
+
+        // Execute DAO decision
+    }
+}
+```
+
+### 3. Cross-Chain Bridge
+
+```solidity
+contract ThresholdBridge is CGGMP21Verifier {
+    // Validators sign cross-chain messages
+    function relayMessage(
+        uint256 sourceChain,
+        bytes calldata message,
+        bytes calldata validatorSig
+    ) external {
+        bytes32 messageHash = keccak256(abi.encodePacked(
+            sourceChain,
+            block.chainid,
+            message
+        ));
+
+        verifyCGGMP21Signature(
+            VALIDATOR_THRESHOLD,
+            TOTAL_VALIDATORS,
+            validatorPublicKey,
+            messageHash,
+            validatorSig
+        );
+
+        // Process cross-chain message
+    }
+}
+```
+
+## Security Considerations
+
+### Threshold Selection
+
+- **2-of-3**: Small teams, personal wallets
+- **3-of-5**: Standard multi-sig, small DAOs
+- **5-of-7**: Medium security, trading firms
+- **7-of-10** or higher: High security, institutional custody
+
+### Key Management
+
+- **Key Refresh**: Periodically refresh shares for proactive security
+- **Backup Shares**: Securely backup threshold shares
+- **Identifiable Aborts**: Monitor and remove malicious parties
+- **Share Distribution**: Never store all shares in one location
+
+### Message Hashing
+
+Always hash messages with domain separation:
+
+```solidity
+bytes32 domainHash = keccak256(abi.encodePacked(
+    address(this),
+    block.chainid,
+    "CGGMP21-v1"
+));
+
+bytes32 messageHash = keccak256(abi.encodePacked(
+    domainHash,
+    nonce,
+    data
+));
+```
+

+# Corona Threshold Signature Precompile
+
+Post-quantum threshold signature verification precompile for Lux EVM, implementing the LWE-based two-round threshold signature scheme from [Corona (ePrint 2024/1113)](https://eprint.iacr.org/2024/1113).
+
+## Overview
+
+The Corona Threshold precompile enables verification of lattice-based threshold signatures on-chain, providing post-quantum security for multi-party consensus protocols. This is a critical component of the Quasar quantum consensus mechanism.
+
+**Precompile Address**: `0x020000000000000000000000000000000000000B`
+
+## Features
+
+- **Post-Quantum Security**: Based on Learning With Errors (LWE) lattice problem
+- **Threshold Signatures**: Supports t-of-n threshold schemes
+- **Two-Round Protocol**: Efficient distributed signing
+- **Quasar Integration**: Native support for quantum consensus validators
+- **Flexible Thresholds**: Configurable from 1-of-n to n-of-n
+
+## Algorithm
+
+Corona implements a threshold signature scheme based on:
+- **Lattice Cryptography**: LWE problem hardness
+- **Ring Learning With Errors**: Polynomial ring operations
+- **Threshold Secret Sharing**: Shamir's secret sharing over rings
+- **Two-Round Protocol**: Efficient distributed key generation and signing
+
+### Parameters
+
+From `corona/sign/config.go`:
+
+| Parameter | Value | Description |
+|-----------|-------|-------------|
+| M | 8 | Matrix rows |
+| N | 7 | Matrix columns |
+| Dbar | 48 | Signature dimension |
+| Q | 0x1000000004A01 | Prime modulus (48-bit) |
+| LogN | 8 | Ring dimension log (256) |
+| SigmaE | 6.108 | Error distribution |
+| SigmaStar | 1.73e11 | Masking distribution |
+
+### Security Level
+
+- **Classical**: >128-bit security
+- **Quantum**: Resistant to Shor's algorithm
+- **Hardness**: Based on LWE with modulus Q and dimension 256
+
+## Gas Costs
+
+| Operation | Formula | Example |
+|-----------|---------|---------|
+| Base Cost | 150,000 | Fixed cost |
+| Per Party | 10,000 × n | Cost per party |
+| **2 parties** | 150,000 + 20,000 | **170,000 gas** |
+| **3 parties** | 150,000 + 30,000 | **180,000 gas** |
+| **5 parties** | 150,000 + 50,000 | **200,000 gas** |
+| **10 parties** | 150,000 + 100,000 | **250,000 gas** |
+
+## Input Format
+
+```
+Offset  | Size | Field
+--------|------|------------------
+0-4     | 4    | threshold (uint32)
+4-8     | 4    | totalParties (uint32)
+8-40    | 32   | messageHash (bytes32)
+40-...  | ~4KB | signature (variable)
+```
+
+### Signature Components
+
+The signature consists of serialized lattice elements:
+- **c**: Challenge polynomial (256 bytes)
+- **z**: Response vector (N × 256 bytes = 1,792 bytes)
+- **Delta**: Difference vector (M × 256 bytes = 2,048 bytes)
+- **A**: Public matrix (M × N × 256 bytes = 14,336 bytes)
+- **bTilde**: Rounded vector (M × 256 bytes = 2,048 bytes)
+
+**Total**: ~20KB per signature
+
+## Usage
+
+### Solidity
+
+```solidity
+import "./ICoronaThreshold.sol";
+
+contract MyContract is CoronaThresholdVerifier {
+    function verifyConsensus(
+        bytes32 messageHash,
+        bytes calldata signature
+    ) external view returns (bool) {
+        // 2-of-3 threshold
+        return verifyThresholdSignature(
+            2,  // threshold
+            3,  // total parties
+            messageHash,
+            signature
+        );
+    }
+
+    function processSignedData(
+        bytes32 messageHash,
+        bytes calldata signature
+    ) external {
+        // Revert if invalid
+        CoronaThresholdLib.verifyOrRevert(
+            2, 3, messageHash, signature
+        );
+
+        // Process data - signature is valid
+    }
+}
+```
+
+### TypeScript/ethers.js
+
+```typescript
+import { ethers } from 'ethers';
+
+const CORONA_THRESHOLD = '0x020000000000000000000000000000000000000B';
+
+const abi = [
+    'function verifyThreshold(uint32,uint32,bytes32,bytes) view returns(bool)'
+];
+
+const precompile = new ethers.Contract(CORONA_THRESHOLD, abi, provider);
+
+// Verify 2-of-3 threshold signature
+const isValid = await precompile.verifyThreshold(
+    2,                    // threshold
+    3,                    // total parties
+    messageHash,          // bytes32
+    signatureBytes        // bytes
+);
+```
+
+### Go
+
+```go
+import (
+    "corona/sign"
+    "github.com/luxfi/lattice/v6/ring"
+)
+
+// Generate threshold signature (off-chain)
+threshold := 2
+totalParties := 3
+
+// Initialize rings
+r, _ := ring.NewRing(1<<sign.LogN, []uint64{sign.Q})
+r_xi, _ := ring.NewRing(1<<sign.LogN, []uint64{sign.QXi})
+r_nu, _ := ring.NewRing(1<<sign.LogN, []uint64{sign.QNu})
+
+// Run threshold signing protocol
+// ... (see corona/main.go for full example)
+
+// Verify signature
+valid := sign.Verify(r, r_xi, r_nu, z, A, mu, bTilde, c, Delta)
+```
+
+## Protocol Flow
+
+### Setup Phase
+1. Trusted dealer generates keys using `sign.Gen()`
+2. Secret shares distributed to n parties
+3. Public parameters (A, b) published
+
+### Signing Phase (Two Rounds)
+
+**Round 1**: Each party generates masking polynomials
+```go
+D_i, MACs_i := party.SignRound1(A, sid, PRFKey, T)
+```
+
+**Round 2 Preprocess**: Verify MACs and combine D matrices
+```go
+valid, DSum, hash := party.SignRound2Preprocess(A, b, D, MACs, sid, T)
+```
+
+**Round 2**: Each party generates signature share
+```go
+z_i := party.SignRound2(A, bTilde, DSum, sid, mu, T, PRFKey, hash)
+```
+
+**Finalize**: Combiner aggregates shares
+```go
+c, z_sum, Delta := party.SignFinalize(z, A, bTilde)
+```
+
+### Verification
+```go
+valid := sign.Verify(r, r_xi, r_nu, z, A, mu, bTilde, c, Delta)
+```
+
+## Quasar Consensus Integration
+
+The Corona threshold precompile is designed for Quasar consensus:
+
+```solidity
+contract QuasarConsensus {
+    uint32 constant VALIDATORS = 5;
+    uint32 constant THRESHOLD = 4; // 4-of-5 for finality
+
+    function finalizeBlock(
+        bytes32 blockHash,
+        bytes calldata validatorSignature
+    ) external {
+        // Verify 4-of-5 validators signed
+        CoronaThresholdLib.verifyOrRevert(
+            THRESHOLD,
+            VALIDATORS,
+            blockHash,
+            validatorSignature
+        );
+
+        // Block is finalized with quantum-resistant proof
+        emit BlockFinalized(blockHash);
+    }
+}
+```
+
+## Security Considerations
+
+### Post-Quantum Security
+- **Quantum Attacks**: Resistant to Shor's algorithm
+- **Classical Attacks**: >128-bit security under LWE assumption
+- **Side Channels**: Constant-time operations in lattice library
+
+### Threshold Properties
+- **Unforgeability**: Cannot forge signature without t parties
+- **Robustness**: Works with any subset of size t
+- **Non-interactivity**: After setup, signing is non-interactive per party
+
+### Network Security
+- **MAC Protection**: Message authentication codes prevent tampering
+- **Replay Protection**: Session IDs prevent signature replay
+- **Rank Checks**: Full rank verification prevents malicious matrices
+
+## Performance
+
+### Benchmarks (Apple M1 Max)
+
+| Operation | Time | Gas |
+|-----------|------|-----|
+| 2-of-3 verify | ~2.5ms | 170,000 |
+| 3-of-5 verify | ~3.8ms | 200,000 |
+| 5-of-7 verify | ~5.2ms | 220,000 |
+
+### Comparison with Other Schemes
+
+| Scheme | Signature Size | Verify Time | Quantum Secure |
+|--------|---------------|-------------|----------------|
+| ECDSA (secp256k1) | 65 bytes | ~88μs | ❌ |
+| BLS | 96 bytes | ~2.1ms | ❌ |
+| **Corona** | **~20KB** | **~3.8ms** | **✅** |
+| ML-DSA-65 | 3.3KB | ~108μs | ✅ |
+| SLH-DSA | 7.9KB | ~4.2ms | ✅ |
+
+**Trade-offs**:
+- ✅ Post-quantum security
+- ✅ Threshold signatures
+- ✅ Two-round protocol
+- ⚠️ Large signature size (~20KB)
+- ⚠️ Higher verification time
+
+## Testing
+
+```bash
+# Run tests
+cd /Users/z/work/lux/standard/src/precompiles/corona-threshold
+go test -v
+
+# Run benchmarks
+go test -bench=. -benchmem
+
+# Test with specific threshold
+go test -run TestCoronaThresholdVerify_3of5
+```
+
+### Test Coverage
+
+- ✅ 2-of-3 threshold signature
+- ✅ 3-of-5 threshold signature
+- ✅ Full threshold (n-of-n)
+- ✅ Invalid signature rejection
+- ✅ Wrong message rejection
+- ✅ Threshold not met rejection
+- ✅ Input validation
+- ✅ Gas cost calculation
+
+## Migration from Classical Signatures
+
+### From ECDSA
+```solidity
+// Before (ECDSA)
+function verify(bytes32 hash, bytes memory sig) public view {
+    address signer = ECDSA.recover(hash, sig);
+    require(isAuthorized(signer), "Unauthorized");
+}
+
+// After (Corona Threshold)
+function verify(bytes32 hash, bytes memory sig) public view {
+    CoronaThresholdLib.verifyOrRevert(
+        THRESHOLD,
+        TOTAL_SIGNERS,
+        hash,
+        sig
+    );
+}
+```
+
+### From BLS
+```solidity
+// Before (BLS aggregate)
+function verify(bytes32 hash, bytes memory sig) public view {
+    require(BLS.verify(aggregateKey, hash, sig), "Invalid");
+}
+
+// After (Corona Threshold)
+function verify(bytes32 hash, bytes memory sig) public view {
+    require(
+        verifyThresholdSignature(THRESHOLD, N, hash, sig),
+        "Invalid"
+    );

+# FROST Threshold Signature Precompile
+
+## Overview
+
+The FROST (Flexible Round-Optimized Schnorr Threshold) precompile enables efficient threshold signature verification for Schnorr-based signatures. FROST allows any t-of-n parties to collaboratively produce a signature that appears to be from a single signer.
+
+**Address**: `0x020000000000000000000000000000000000000C`
+
+## Features
+
+- **Threshold Signatures**: Any t out of n parties can sign
+- **Schnorr-Based**: Compatible with Ed25519 and secp256k1 Schnorr
+- **Bitcoin Taproot**: Used for Bitcoin BIP-340/341 multisig
+- **Efficient**: Lower gas cost than ECDSA threshold (CGGMP21)
+- **Standardized**: Based on IETF FROST specification
+
+## Algorithm
+
+FROST is a threshold signature scheme where:
+- **n** total parties hold shares of a private key
+- Any **t** parties can collaborate to produce a valid signature
+- The signature is indistinguishable from a single-party Schnorr signature
+- Compatible with BIP-340 (Bitcoin Taproot) and Ed25519
+
+### Key Properties
+
+- **Non-Interactive**: After setup, signing requires minimal rounds
+- **Compact Signatures**: 64 bytes (standard Schnorr)
+- **Flexible Threshold**: Configurable t-of-n threshold
+- **Efficient Verification**: Standard Schnorr verification
+
+## Specifications
+
+### Input Format
+
+Total size: **136 bytes** (minimum)
+
+| Offset | Size | Field | Description |
+|--------|------|-------|-------------|
+| 0-3 | 4 bytes | threshold | Minimum signers required (t) |
+| 4-7 | 4 bytes | totalSigners | Total number of parties (n) |
+| 8-39 | 32 bytes | publicKey | Aggregated public key |
+| 40-71 | 32 bytes | messageHash | SHA-256 hash of message |
+| 72-135 | 64 bytes | signature | Schnorr signature (R \|\| s) |
+
+### Output Format
+
+**32 bytes**: Boolean result as uint256
+- `0x0000...0001` = Valid signature
+- `0x0000...0000` = Invalid signature
+
+### Gas Costs
+
+| Operation | Base Gas | Per-Signer Gas |
+|-----------|----------|----------------|
+| FROST Verify | 50,000 | 5,000 |
+
+**Examples**:
+- 2-of-3 threshold: 50,000 + (3 × 5,000) = **65,000 gas**
+- 3-of-5 threshold: 50,000 + (5 × 5,000) = **75,000 gas**
+- 10-of-15 threshold: 50,000 + (15 × 5,000) = **125,000 gas**

+## Use Cases
+
+### Bitcoin Taproot Multisig
+
+```solidity
+contract TaprootMultisig {
+    using FROSTLib for *;
+
+    bytes32 public taprootPublicKey;
+    uint32 public constant THRESHOLD = 2;
+    uint32 public constant TOTAL_SIGNERS = 3;
+
+    function spendBitcoin(
+        bytes32 messageHash,
+        bytes calldata signature
+    ) external {
+        FROSTLib.verifyOrRevert(
+            THRESHOLD,
+            TOTAL_SIGNERS,
+            taprootPublicKey,
+            messageHash,
+            signature
+        );
+
+        // Execute Bitcoin spend
+    }
+}
+```
+
+### Multi-Chain Governance
+
+```solidity
+contract CrossChainGovernance is FROSTVerifier {
+    struct Proposal {
+        bytes32 proposalHash;
+        uint256 votesFor;
+        bool executed;
+    }
+
+    mapping(uint256 => Proposal) public proposals;
+
+    function executeProposal(
+        uint256 proposalId,
+        bytes calldata thresholdSignature
+    ) external {
+        Proposal storage proposal = proposals[proposalId];
+
+        // Verify threshold signature from governance committee
+        verifyFROSTSignature(
+            GOVERNANCE_THRESHOLD,
+            GOVERNANCE_TOTAL,
+            GOVERNANCE_PUBLIC_KEY,
+            proposal.proposalHash,
+            thresholdSignature
+        );
+
+        // Execute proposal
+        proposal.executed = true;
+    }
+}
+```
+
+## Security Considerations
+
+### Threshold Selection
+
+- **2-of-3**: Common for small multisig wallets
+- **3-of-5**: Standard for governance
+- **5-of-7** or **7-of-10**: High-security applications
+- Never use 1-of-n (defeats the purpose)
+
+### Message Hashing
+
+Always hash messages before signing:
+
+```solidity
+bytes32 messageHash = keccak256(abi.encodePacked(data));
+```
+
+### Public Key Management
+
+- Store aggregated public keys securely on-chain
+- Validate threshold parameters (t ≤ n)
+- Use events to track configuration changes
+
+## Performance

+# ML-DSA Precompile (FIPS 204)
+
+Post-quantum digital signature verification precompile for Lux EVM.
+
+## Overview
+
+The ML-DSA (Module-Lattice-Based Digital Signature Algorithm) precompile provides quantum-resistant signature verification based on the Dilithium algorithm and standardized in FIPS 204.
+
+**Precompile Address**: `0x0200000000000000000000000000000000000006`
+
+## Features
+
+- **Quantum Resistant**: Secure against attacks from both classical and quantum computers
+- **NIST Standardized**: Implements FIPS 204 (ML-DSA-65)
+- **High Performance**: ~108μs verification time on Apple M1
+- **Security Level 3**: Equivalent to AES-192 security
+
+## Specifications
+
+### ML-DSA-65 Parameters
+
+| Parameter | Value |
+|-----------|-------|
+| Public Key Size | 1952 bytes |
+| Signature Size | 3309 bytes |
+| Security Level | NIST Level 3 |
+| Quantum Security | ~192 bits |
+
+### Gas Costs
+
+| Operation | Cost |
+|-----------|------|
+| Base Cost | 100,000 gas |
+| Per Message Byte | 10 gas |
+
+**Examples:**
+- Empty message: 100,000 gas
+- 100-byte message: 101,000 gas
+- 1KB message: 110,240 gas
+- 10KB message: 202,400 gas
+
+## Input Format
+
+The precompile expects a specific binary input format:
+
+```
+[Offset] [Size]   [Description]
+0        1952     ML-DSA-65 public key
+1952     32       Message length (uint256, big-endian)
+1984     3309     ML-DSA-65 signature
+5293     variable Message bytes
+```
+
+## Output Format
+
+Returns a 32-byte word:
+- `0x0000...0001` - Signature is **valid**
+- `0x0000...0000` - Signature is **invalid**
+
+## Usage
+
+### Solidity
+
+```solidity
+// Interface
+IMLDSA mldsa = IMLDSA(0x0200000000000000000000000000000000000006);
+bool isValid = mldsa.verify(publicKey, message, signature);
+require(isValid, "Invalid signature");
+
+// Using library
+using MLDSALib for bytes;
+
+function verifyData(
+    bytes calldata publicKey,
+    bytes calldata data,
+    bytes calldata signature
+) external view {
+    MLDSALib.verifyOrRevert(publicKey, data, signature);
+    // Signature is valid
+}
+
+// Gas estimation
+uint256 estimatedGas = MLDSALib.estimateGas(message.length);
+```
+
+### TypeScript/ethers.js
+
+```typescript
+import { ethers } from 'ethers';
+
+const MLDSA_ADDRESS = '0x0200000000000000000000000000000000000006';
+
+// ABI for the verify function
+const abi = [
+  'function verify(bytes calldata publicKey, bytes calldata message, bytes calldata signature) external view returns (bool)'
+];
+
+const mldsa = new ethers.Contract(MLDSA_ADDRESS, abi, provider);
+
+// Verify signature
+const isValid = await mldsa.verify(publicKey, message, signature);
+console.log('Signature valid:', isValid);
+```
+
+### Go
+
+```go
+import (
+    "github.com/luxfi/node/crypto/mldsa"
+    "github.com/luxfi/evm/precompile/contracts/mldsa"
+)
+
+// Generate key pair
+seed := make([]byte, 32)
+sk, _ := mldsa.NewSigningKey(mldsa.ModeML_DSA_65, seed)
+pk := sk.PublicKey()
+
+// Sign message
+message := []byte("Hello, quantum world!")
+signature := sk.Sign(message, nil)
+
+// Verify via precompile
+input := prepareMLDSAInput(pk, message, signature)
+result, gas, err := mldsa.MLDSAVerifyPrecompile.Run(
+    nil, addr, addr, input, 200000, false,
+)
+
+valid := result[31] == 1 // Check last byte
+```
+
+## Performance Benchmarks
+
+Measured on Apple M1 Max:
+
+| Message Size | Verification Time | Gas Used |
+|--------------|-------------------|----------|
+| 18 bytes (small) | ~170μs | 100,180 |
+| 10KB (large) | ~218μs | 202,400 |
+
+**Memory Usage:**
+- 33,314 bytes per operation
+- 6 allocations per operation
+
+## Security Considerations
+
+1. **Quantum Resistance**: ML-DSA-65 provides Level 3 security (~192-bit quantum security)
+2. **Side-Channel Protection**: Implementation uses constant-time operations
+3. **FIPS 204 Compliance**: Follows NIST's standardized algorithm
+4. **No Context Support**: Current implementation doesn't support context strings (passes empty context)
+
+## Comparison with Other Algorithms
+
+| Algorithm | Type | Signature Size | Verify Time | Quantum Secure |
+|-----------|------|----------------|-------------|----------------|
+| ECDSA (secp256k1) | Classical | 65 bytes | ~88μs | ❌ No |
+| ML-DSA-65 | Post-Quantum | 3,309 bytes | ~108μs | ✅ Yes |
+| SLH-DSA-128s | Post-Quantum | 7,856 bytes | ~4.2ms | ✅ Yes |
+
+## Migration Guide
+
+### From ECDSA to ML-DSA
+
+```solidity
+// Old ECDSA verification
+bytes32 hash = keccak256(message);
+address signer = ecrecover(hash, v, r, s);
+require(signer == expectedSigner, "Invalid signature");
+
+// New ML-DSA verification
+IMLDSA mldsa = IMLDSA(0x0200000000000000000000000000000000000006);
+bool valid = mldsa.verify(mldsaPublicKey, message, mldsaSignature);
+require(valid, "Invalid ML-DSA signature");
+```
+
+## Testing
+
+```bash
+# Run unit tests
+cd /Users/z/work/lux/evm/precompile/contracts/mldsa
+go test -v
+
+# Run benchmarks
+go test -bench=. -benchmem
+
+# Test with different message sizes
+go test -v -run TestMLDSAVerify_LargeMessage

+# SLH-DSA Signature Verification Precompile
+
+## Overview
+
+This precompile implements **SLH-DSA (Stateless Hash-Based Digital Signature Algorithm)** signature verification as specified in [FIPS 205](https://csrc.nist.gov/pubs/fips/205/final).
+
+**Address**: `0x0200000000000000000000000000000000000007`
+
+## FIPS 205 - SLH-DSA
+
+SLH-DSA (formerly SPHINCS+) is a **post-quantum digital signature scheme** based on hash functions. It provides:
+
+- **Quantum Resistance**: Secure against attacks by quantum computers
+- **Stateless Operation**: No state management required (unlike XMSS)
+- **Minimal Assumptions**: Security based only on collision-resistant hash functions
+- **Conservative Security**: Well-understood hash-based construction
+
+## Parameter Sets
+
+SLH-DSA supports 12 parameter sets across 3 security levels:
+
+### Category 1 (128-bit security)
+| Parameter Set | Hash Function | Signature Size | Sign Speed | Verify Speed |
+|--------------|---------------|----------------|------------|--------------|
+| SHA2-128s | SHA-256 | 7,856 bytes | Slow | Fast |
+| SHA2-128f | SHA-256 | 17,088 bytes | Fast | Fast |
+| SHAKE-128s | SHAKE256 | 7,856 bytes | Slow | Fast |
+| SHAKE-128f | SHAKE256 | 17,088 bytes | Fast | Fast |
+
+### Category 3 (192-bit security)
+| Parameter Set | Hash Function | Signature Size | Sign Speed | Verify Speed |
+|--------------|---------------|----------------|------------|--------------|
+| SHA2-192s | SHA-256/512 | 16,224 bytes | Slow | Fast |
+| SHA2-192f | SHA-256/512 | 35,664 bytes | Fast | Fast |
+| SHAKE-192s | SHAKE256 | 16,224 bytes | Slow | Fast |
+| SHAKE-192f | SHAKE256 | 35,664 bytes | Fast | Fast |
+
+### Category 5 (256-bit security)
+| Parameter Set | Hash Function | Signature Size | Sign Speed | Verify Speed |
+|--------------|---------------|----------------|------------|--------------|
+| SHA2-256s | SHA-512 | 29,792 bytes | Slow | Fast |
+| SHA2-256f | SHA-512 | 49,856 bytes | Fast | Fast |
+| SHAKE-256s | SHAKE256 | 29,792 bytes | Slow | Fast |
+| SHAKE-256f | SHAKE256 | 49,856 bytes | Fast | Fast |
+
+**Trade-offs**:
+- **"s" (small)**: Smaller signatures, slower signing (~300-600ms)
+- **"f" (fast)**: Larger signatures, faster signing (~10-50ms)
+- Verification speed is similar for both variants (~300-600μs)
+
+## Performance Benchmarks
+
+**Apple M1 Max Results**:
+
+| Operation | SHA2-128s | SHA2-256s |
+|-----------|-----------|-----------|
+| Sign | ~309ms | ~603ms |
+| Verify | ~286μs | ~593μs |
+| KeyGen | ~35ms | ~71ms |
+
+**Verification Throughput**:
+- SHA2-128s: ~3,500 signatures/second
+- SHA2-256s: ~1,700 signatures/second
+
+## Gas Costs
+
+```
+Gas = BaseGas + (MessageLength * PerByteGas)
+BaseGas = 15,000
+PerByteGas = 10
+```
+
+**Examples**:
+- Empty message: 15,000 gas
+- 100-byte message: 16,000 gas
+- 1KB message: 25,240 gas
+- 10KB message: 115,000 gas
+
+## Usage
+
+### Solidity Interface
+
+```solidity
+interface ISLHDSA {
+    function verify(
+        bytes calldata publicKey,
+        bytes calldata message,
+        bytes calldata signature
+    ) external view returns (bool valid);
+}
+```
+
+### Example Contract
+
+```solidity
+import {SLHDSAVerifier} from "./ISLHDSA.sol";
+
+contract MyContract is SLHDSAVerifier {
+    function processSignedData(
+        bytes calldata publicKey,
+        bytes calldata data,
+        bytes calldata signature
+    ) external {
+        // Verify signature with automatic revert on failure
+        require(
+            verifySLHDSASignature(publicKey, data, signature),
+            "Invalid signature"
+        );
+        
+        // Process data - signature is valid
+        // ...
+    }
+}
+```
+
+### Using the Library
+
+```solidity
+import {SLHDSALib} from "./ISLHDSA.sol";
+
+contract Example {
+    function verifyWithRevert(
+        bytes memory publicKey,
+        bytes memory message,
+        bytes memory signature
+    ) public view {
+        // Automatically reverts if signature is invalid
+        SLHDSALib.verifyOrRevert(publicKey, message, signature);
+    }
+    
+    function estimateVerificationGas(uint256 messageLength) 
+        public 
+        pure 
+        returns (uint256) 
+    {
+        return SLHDSALib.estimateGas(messageLength);
+    }
+}
+```
+
+### TypeScript/ethers.js
+
+```typescript
+const SLHDSA_ADDRESS = '0x0200000000000000000000000000000000000007';
+const SLHDSA = new ethers.Contract(
+    SLHDSA_ADDRESS,
+    ['function verify(bytes,bytes,bytes) view returns(bool)'],
+    provider
+);
+
+const isValid = await SLHDSA.verify(publicKey, message, signature);
+console.log('Signature valid:', isValid);
+```
+
+## Input Format
+
+The precompile expects input in the following format:
+
+```
+[mode(1 byte)] [pubKeyLen(2 bytes)] [publicKey] [msgLen(2 bytes)] [message] [signature]
+```
+
+**Fields**:
+1. `mode` (1 byte): Parameter set identifier (0-11)
+   - 0: SHA2-128s, 1: SHAKE-128s, 2: SHA2-128f, 3: SHAKE-128f
+   - 4: SHA2-192s, 5: SHAKE-192s, 6: SHA2-192f, 7: SHAKE-192f
+   - 8: SHA2-256s, 9: SHAKE-256s, 10: SHA2-256f, 11: SHAKE-256f
+2. `pubKeyLen` (2 bytes, big-endian): Length of public key
+3. `publicKey` (32, 48, or 64 bytes): The SLH-DSA public key
+4. `msgLen` (2 bytes, big-endian): Length of message
+5. `message` (variable): The message that was signed
+6. `signature` (7856-49856 bytes): The SLH-DSA signature
+
+## Output Format
+
+Single byte indicating verification result:
+- `0x01`: Signature is valid
+- `0x00`: Signature is invalid
+
+## Security Considerations
+
+### Post-Quantum Security
+
+SLH-DSA provides security against quantum computer attacks because:
+1. Based on hash functions (no algebraic structure to exploit)
+2. No known quantum algorithm for breaking collision resistance
+3. Conservative security assumptions
+
+### Hash Function Requirements
+
+- **SHA-2**: Industry standard, widely deployed
+- **SHAKE**: SHA-3 based, newer but standardized
+
+### Signature Size Trade-offs
+
+Large signatures are a characteristic of hash-based schemes:
+- **Small variants** ("s"): More efficient for storage
+- **Fast variants** ("f"): Better for high-throughput signing
+
+### Recommended Parameter Sets
+
+- **General use**: SHA2-128s or SHA2-256s
+  - Smaller signatures, acceptable signing speed for most applications
+  
+- **High-throughput signing**: SHA2-128f or SHA2-256f
+  - When signing speed is critical and storage is available
+  
+- **Conservative security**: SHA2-256s
+  - Maximum security level, reasonable signature size
+
+## Comparison with Other Schemes
+
+| Scheme | Type | Signature Size | Verify Time | Quantum Secure |
+|--------|------|----------------|-------------|----------------|
+| ECDSA | Elliptic Curve | 65 bytes | ~88μs | ❌ |
+| ML-DSA-65 | Lattice | 3,309 bytes | ~108μs | ✅ |
+| SLH-DSA-SHA2-128s | Hash-based | 7,856 bytes | ~286μs | ✅ |
+| SLH-DSA-SHA2-256s | Hash-based | 29,792 bytes | ~593μs | ✅ |
+
+**Trade-offs**:
+- SLH-DSA has larger signatures than ML-DSA
+- SLH-DSA has slower verification than ML-DSA
+- SLH-DSA has more conservative security assumptions
+- SLH-DSA requires no state management
+
+## Implementation Details
+
+- **Library**: Cloudflare CIRCL v1.6.1
+- **Standard**: FIPS 205 (Final)
+- **Algorithm**: SPHINCS+ with FIPS 205 parameters
+- **Hash Functions**: SHA-256, SHA-512, SHAKE256
+- **Security Levels**: 128-bit, 192-bit, 256-bit
+
+## Error Handling
+
+The precompile returns `0x00` (invalid) for:
+- Invalid mode identifier
+- Incorrect public key size
+- Incorrect signature size
+- Failed signature verification
+- Malformed input
+
+No exceptions are thrown - all errors result in `0x00` output.
+
+## Gas Optimization Tips
+
+1. **Batch Verification**: Group multiple verifications to amortize overhead
+2. **Off-chain Verification**: Verify off-chain when possible, only verify on-chain when necessary
+3. **Signature Aggregation**: Use BLS or other aggregatable schemes when applicable
+4. **Parameter Selection**: Use 128-bit security when 256-bit is not required
+
+## Migration from Classical Signatures
+
+When migrating from ECDSA to SLH-DSA:
+
+1. **Storage**: Account for larger signatures in data structures
+2. **Gas Costs**: Budget for higher verification costs
+3. **Signing Infrastructure**: Update to support SLH-DSA key generation
+4. **Backwards Compatibility**: Support both schemes during transition

+# Integrating Lux Warp Messaging into the EVM
+
+Lux Warp Messaging offers a basic primitive to enable Cross-L1 communication on the Lux Network.
+
+It is intended to allow communication between arbitrary Custom Virtual Machines (including, but not limited to Subnet-EVM and Coreth).
+
+## How does Lux Warp Messaging Work?
+
+Lux Warp Messaging uses BLS Multi-Signatures with Public-Key Aggregation where every Lux validator registers a public key alongside its NodeID on the Lux P-Chain.
+
+Every node tracking an Lux L1 has read access to the Lux P-Chain. This provides weighted sets of BLS Public Keys that correspond to the validator sets of each L1 on the Lux Network. Lux Warp Messaging provides a basic primitive for signing and verifying messages between L1s: the receiving network can verify whether an aggregation of signatures from a set of source L1 validators represents a threshold of stake large enough for the receiving network to process the message.
+
+For more details on Lux Warp Messaging, see the Luxd [Warp README](https://github.com/luxfi/luxd/blob/master/vms/platformvm/warp/README.md).
+
+### Flow of Sending / Receiving a Warp Message within the EVM
+
+The Lux Warp Precompile enables this flow to send a message from blockchain A to blockchain B:
+
+1. Call the Warp Precompile `sendWarpMessage` function with the arguments for the `UnsignedMessage`
+2. Warp Precompile emits an event / log containing the `UnsignedMessage` specified by the caller of `sendWarpMessage`
+3. Network accepts the block containing the `UnsignedMessage` in the log, so that validators are willing to sign the message
+4. An off-chain relayer queries the validators for their signatures of the message and aggregates the signatures to create a `SignedMessage`
+5. The off-chain relayer encodes the `SignedMessage` as the [predicate](#predicate-encoding) in the AccessList of a transaction to deliver on blockchain B
+6. The transaction is delivered on blockchain B, the signature is verified prior to executing the block, and the message is accessible via the Warp Precompile's `getVerifiedWarpMessage` during the execution of that transaction
+
+### Warp Precompile
+
+The Warp Precompile is broken down into three functions defined in the Solidity interface file [here](../../../contracts/contracts/interfaces/IWarpMessenger.sol).
+
+#### sendWarpMessage
+
+`sendWarpMessage` is used to send a verifiable message. Calling this function results in sending a message with the following contents:
+
+- `SourceChainID` - blockchainID of the sourceChain on the Lux P-Chain
+- `SourceAddress` - `msg.sender` encoded as a 32 byte value that calls `sendWarpMessage`
+- `Payload` - `payload` argument specified in the call to `sendWarpMessage` emitted as the unindexed data of the resulting log
+
+Calling this function will issue a `SendWarpMessage` event from the Warp Precompile. Since the EVM limits the number of topics to 4 including the EventID, this message includes only the topics that would be expected to help filter messages emitted from the Warp Precompile the most.
+
+Specifically, the `payload` is not emitted as a topic because each topic must be encoded as a hash. Therefore, we opt to take advantage of each possible topic to maximize the possible filtering for emitted Warp Messages.
+
+Additionally, the `SourceChainID` is excluded because anyone parsing the chain can be expected to already know the blockchainID. Therefore, the `SendWarpMessage` event includes the indexable attributes:
+
+- `sender`
+- The `messageID` of the unsigned message (sha256 of the unsigned message)
+
+The actual `message` is the entire [Lux Warp Unsigned Message](https://github.com/luxfi/luxd/blob/master/vms/platformvm/warp/unsigned_message.go#L14) including an [AddressedCall](https://github.com/luxfi/luxd/tree/master/vms/platformvm/warp/payload#addressedcall). The unsigned message is emitted as the unindexed data in the log.
+
+#### getVerifiedMessage
+
+`getVerifiedMessage` is used to read the contents of the delivered Lux Warp Message into the expected format.
+
+It returns the message if present and a boolean indicating if a message is present.
+
+To use this function, the transaction must include the signed Lux Warp Message encoded in the [predicate](#predicate-encoding) of the transaction. Prior to executing a block, the VM iterates through transactions and pre-verifies all predicates. If a transaction's predicate is invalid, then it is considered invalid to include in the block and dropped.
+
+This leads to the following advantages:
+
+1. The EVM execution does not need to verify the Warp Message at runtime (no signature verification or external calls to the P-Chain)
+2. The EVM can deterministically re-execute and re-verify blocks assuming the predicate was verified by the network (e.g., in bootstrapping)
+
+This pre-verification is performed using the ProposerVM Block header during [block verification](../../../plugin/evm/block.go#L355) & [block building](../../../miner/worker.go#L200).
+
+#### getBlockchainID
+
+`getBlockchainID` returns the blockchainID of the blockchain that the VM is running on.
+
+This is different from the conventional Ethereum ChainID registered to [ChainList](https://chainlist.org/).
+
+The `blockchainID` in Lux refers to the txID that created the blockchain on the Lux P-Chain ([docs](https://docs.lux.network/specs/platform-transaction-serialization#unsigned-create-chain-tx)).
+
+### Predicate Encoding
+
+Lux Warp Messages are encoded as a signed Lux [Warp Message](https://github.com/luxfi/luxd/blob/master/vms/platformvm/warp/message.go) where the [UnsignedMessage](https://github.com/luxfi/luxd/blob/master/vms/platformvm/warp/unsigned_message.go)'s payload includes an [AddressedPayload](https://github.com/luxfi/luxd/blob/master/vms/platformvm/warp/payload/payload.go).
+
+Since the predicate is encoded into the [Transaction Access List](https://eips.ethereum.org/EIPS/eip-2930), it is packed into 32 byte hashes intended to declare storage slots that should be pre-warmed into the cache prior to transaction execution.
+
+Therefore, we use the [Predicate Utils](https://github.com/luxfi/evm/blob/master/predicate/Predicate.md) package to encode the actual byte slice of size N into the access list.
+
+### Performance Optimization: Primary Network to Lux L1
+
+The Primary Network has a large validator set compared to most Subnets and L1s, which makes Warp signature collection and verification from the entire Primary Network validator set costly. All Subnets and L1s track at least one blockchain of the Primary Network, so we can instead optimize this by using the validator set of the receiving L1 instead of the Primary Network for certain Warp messages.
+
+#### Subnets
+
+Recall that Lux Subnet validators must also validate the Primary Network, so it tracks all of the blockchains in the Primary Network (X, C, and P-Chains).
+
+When an Lux Subnet receives a message from a blockchain on the Primary Network, we use the validator set of the receiving Subnet instead of the entire network when validating the message. 
+
+Sending messages from the X, C, or P-Chain remains unchanged.
+However, when the Subnet receives the message, it changes the semantics to the following:
+
+1. Read the `SourceChainID` of the signed message
+2. Look up the `SubnetID` that validates `SourceChainID`. In this case it will be the Primary Network's `SubnetID`
+3. Look up the validator set of the Subnet (instead of the Primary Network) and the registered BLS Public Keys of the Subnet validators at the P-Chain height specified by the ProposerVM header
+4. Continue Warp Message verification using the validator set of the Subnet instead of the Primary Network
+
+This means that Primary Network to Subnet communication only requires a threshold of stake on the receiving Subnet to sign the message instead of a threshold of stake for the entire Primary Network.
+
+Since the security of the Subnet is provided by trust in its validator set, requiring a threshold of stake from the receiving Subnet's validator set instead of the whole Primary Network does not meaningfully change the security of the receiving L1.
+
+Note: this special case is ONLY applied during Warp Message verification. The message sent by the Primary Network will still contain the blockchainID of the Primary Network chain that sent the message as the sourceChainID and signatures will be served by querying the source chain directly.
+
+#### L1s
+
+Lux L1s are only required to sync the P-Chain, but are not required to validate the Primary Network. Therefore, **for L1s, this optimization only applies to Warp messages sent by the P-Chain.** The rest of the description of this optimization in the above section applies to L1s.
+
+Note that **in order to properly verify messages from the C-Chain and X-Chain, the Warp precompile must be configured with `requirePrimaryNetworkSigners` set to `true`**. Otherwise, we will attempt to verify the message signature against the receiving L1's validator set, which is not required to track the C-Chain or X-Chain, and therefore will not in general be able to produce a valid Warp message.
+
+## Design Considerations
+
+### Re-Processing Historical Blocks
+
+Lux Warp Messaging depends on the Lux P-Chain state at the P-Chain height specified by the ProposerVM block header.
+
+Verifying a message requires looking up the validator set of the source L1 on the P-Chain. To support this, Lux Warp Messaging uses the ProposerVM header, which includes the P-Chain height it was issued at as the canonical point to lookup the source L1's validator set.
+
+This means verifying the Warp Message and therefore the state transition on a block depends on state that is external to the blockchain itself: the P-Chain.
+
+The Lux P-Chain tracks only its current state and reverse diff layers (reversing the changes from past blocks) in order to re-calculate the validator set at a historical height. This means calculating a very old validator set that is used to verify a Warp Message in an old block may become prohibitively expensive.
+
+Therefore, we need a heuristic to ensure that the network can correctly re-process old blocks (note: re-processing old blocks is a requirement to perform bootstrapping and is used in some VMs to serve or verify historical data).
+
+As a result, we require that the block itself provides a deterministic hint which determines which Lux Warp Messages were considered valid/invalid during the block's execution. This ensures that we can always re-process blocks and use the hint to decide whether an Lux Warp Message should be treated as valid/invalid even after the P-Chain state that was used at the original execution time may no longer support fast lookups.
+
+To provide that hint, we've explored two designs:
+
+1. Include a predicate in the transaction to ensure any referenced message is valid
+2. Append the results of checking whether a Warp Message is valid/invalid to the block data itself
+
+The current implementation uses option (1).
+
+The original reason for this was that the notion of predicates for precompiles was designed with Shared Memory in mind. In the case of shared memory, there is no canonical "P-Chain height" in the block which determines whether or not Lux Warp Messages are valid.
+
+Instead, the VM interprets a shared memory import operation as valid as soon as the UTXO is available in shared memory. This means that if it were up to the block producer to staple the valid/invalid results of whether or not an attempted atomic operation should be treated as valid, a byzantine block producer could arbitrarily report that such atomic operations were invalid and cause a griefing attack to burn the gas of users that attempted to perform an import.
+
+Therefore, a transaction specified predicate is required to implement the shared memory precompile to prevent such a griefing attack.
+
+In contrast, Lux Warp Messages are validated within the context of an exact P-Chain height. Therefore, if a block producer attempted to lie about the validity of such a message, the network would interpret that block as invalid.
+
+### Guarantees Offered by Warp Precompile vs. Built on Top
+
+#### Guarantees Offered by Warp Precompile
+
+The Warp Precompile was designed with the intention of minimizing the trusted computing base for the VM as much as possible. Therefore, it makes several tradeoffs which encourage users to use protocols built ON TOP of the Warp Precompile itself as opposed to directly using the Warp Precompile.
+
+The Warp Precompile itself provides ONLY the following ability:
+
+- Emit a verifiable message from (Address A, Blockchain A) to (Address B, Blockchain B) that can be verified by the destination chain
+
+#### Explicitly Not Provided / Built on Top
+
+The Warp Precompile itself does not provide any guarantees of:
+
+- Eventual message delivery (may require re-send on blockchain A and additional assumptions about off-chain relayers and chain progress)
+- Ordering of messages (requires ordering provided a layer above)
+- Replay protection (requires replay protection provided a layer above)
