// Signature is 3.3KB for ML-DSA-65
|
||||
```
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Smart Contract Using PQ Verification
|
||||
```solidity
|
||||
contract PostQuantumVault {
|
||||
address constant ML_DSA_65_VERIFY = 0x0000000000000000000000000000000000000111;
|
||||
|
||||
function verifyMLDSA(
|
||||
bytes memory pubKey, // 1952 bytes
|
||||
bytes memory message,
|
||||
bytes memory signature // 3293 bytes
|
||||
) public view returns (bool) {
|
||||
bytes memory input = abi.encodePacked(pubKey, message, signature);
|
||||
(bool success, bytes memory result) = ML_DSA_65_VERIFY.staticcall(input);
|
||||
return success && result[0] == 1;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### CLI Key Generation
|
||||
```bash
|
||||
# Generate ML-DSA-65 key (recommended)
|
||||
$ lux key create-pq alice --algorithm ml-dsa-65
|
||||
|
||||
Post-Quantum Key Created Successfully!
|
||||
Algorithm: ML-DSA-65
|
||||
Key Name: alice
|
||||
Saved to: ~/.lux/keys/alice.pq.key
|
||||
|
||||
Key Sizes:
|
||||
Private Key: 4000 bytes
|
||||
Public Key: 1952 bytes
|
||||
Signature: 3293 bytes
|
||||
Security: NIST Level 3 (~192-bit)
|
||||
```
|
||||
|
||||
### Transaction with PQ Signature
|
||||
```go
|
||||
// Using keystore API
|
||||
key, _ := keystore.NewPostQuantumKey(keystore.SignatureMLDSA65)
|
||||
signature, _ := key.Sign(txHash)
|
||||
// Signature is 3293 bytes vs 65 bytes for ECDSA
|
||||
```

|
||||
| Signature Size | 65 bytes | 3,293 bytes | 50x |
|
||||
| Public Key Size | 64 bytes | 1,952 bytes | 30x |

priv, pub, err := mlkem.GenerateKeyPair(rand.Reader, mode)
|
||||
ct, ss, err := pub.Encapsulate(rand.Reader)
|
||||
ss2, err := priv.Decapsulate(ct)

|
||||
**Why**: Essential for privacy-preserving DeFi, anonymous authentication
|
||||
```go
|
||||
// Precompile addresses: 0x01A0-0x01A3
|
||||
crypto/oprf/
|
||||
├── voprf.go // Core VOPRF implementation
|
||||
├── voprf_test.go // Tests

|
||||
// Precompile addresses: 0x01B0-0x01B2
|
||||
crypto/xof/k12/
|
||||
├── k12.go // KangarooTwelve implementation
|
||||

||||
### 4. DLEQ Proofs - **MEDIUM PRIORITY**
|
||||
**Why**: Essential for cross-chain proofs and threshold signatures
|
||||
```go
|
||||
// Precompile addresses: 0x0193-0x0195
|
||||
crypto/zk/dleq/
|
||||
├── dleq.go // Discrete log equality proofs
|
||||
├── schnorr.go // Schnorr knowledge proofs

|
||||
```
|
||||
|
||||
## Implementation Guide
|
||||
|
||||
### Step 1: Import from CIRCL
|
||||
```bash
|
||||
# Add CIRCL dependency
|
||||
go get github.com/cloudflare/circl@latest
|
||||
|
||||
# Import specific packages
|
||||
import (
|
||||
"github.com/cloudflare/circl/oprf"
|
||||
"github.com/cloudflare/circl/hpke"
|
||||
"github.com/cloudflare/circl/xof/k12"
|
||||
)
|
||||
```
|
||||
|
||||
### Step 2: Create Precompile Wrappers
|
||||
```go
|
||||
// Example: VOPRF Precompile
|
||||
package precompile
|
||||
|
||||
type VOPRFEvaluate struct{}
|
||||
|
||||
func (v *VOPRFEvaluate) RequiredGas(input []byte) uint64 {
|
||||
return 200000 // Base cost
|
||||
}
|
||||
|
||||
func (v *VOPRFEvaluate) Run(input []byte) ([]byte, error) {
|
||||
// Parse input: [mode][key][element]
|
||||
// Execute VOPRF evaluation
|
||||
// Return proof + output
|
||||
}
|
||||
```
|
||||
|
||||
### Step 3: Register Precompiles
|
||||
```go
|
||||
// In precompile/export.go
|
||||
func init() {
|
||||
// VOPRF
|
||||
PostQuantumRegistry.contracts[Address{0x01, 0xA0}] = &VOPRFSetup{}
|
||||
PostQuantumRegistry.contracts[Address{0x01, 0xA1}] = &VOPRFEvaluate{}
|
||||
PostQuantumRegistry.contracts[Address{0x01, 0xA2}] = &VOPRFVerify{}
|
||||
|
||||
// HPKE
|
||||
PostQuantumRegistry.contracts[Address{0x01, 0xA4}] = &HPKEEncrypt{}
|
||||
PostQuantumRegistry.contracts[Address{0x01, 0xA5}] = &HPKEDecrypt{}
|
||||
}
|
||||
```
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
### Unit Tests
|
||||

|
||||
func TestVOPRF(t *testing.T) {
|
||||
// Test all VOPRF modes
|
||||
// Test edge cases
|
||||
// Benchmark performance
|
||||
}
|
||||
```
|
||||
|
||||

||||
(bool success, bytes memory output) = VOPRF_EVALUATE.staticcall(input);
|
||||
require(success, "VOPRF failed");
|
||||
return output;
|
||||
}
|
||||
}
|
||||
```
|

## Dependencies
|
||||
|
||||
```go
|
||||
// Required packages
|
||||
github.com/cloudflare/circl v1.3.6 // For VOPRF, HPKE, K12
|
||||
github.com/luxfi/crypto/ipa // Already implemented
|
||||
github.com/ethereum/go-verkle // Reference implementation
|
||||
```
|
||||
|
||||
## Conclusion
|
||||
|
||||
This roadmap positions Lux as the leader in:
|
||||
1. **Stateless Execution**: First non-Ethereum chain with full Verkle support
|
||||
2. **Privacy Technology**: Comprehensive privacy primitive suite
|
||||
3. **Performance**: Optimized cryptography with K12 and precomputed tables
|
||||
4. **Future-Proof**: Ready for post-quantum transition
|
||||
5. **Interoperability**: Compatible with Ethereum's roadmap
|
||||
|
||||
The combination of Verkle trees with advanced CIRCL primitives creates unique capabilities for privacy-preserving stateless execution, enabling entirely new classes of applications on Lux.
