v0.1.0

Initial release of a Go implementation of the Narwhal DAG-based mempool protocol.

Made for personal use. Unaudited. Use at your own risk.

Features

• DAG-based mempool separating data availability from ordering
• Parallel transaction broadcast with no leader bottleneck
• Certificate-based availability guarantees (2f+1 acknowledgments)
• Dual signature schemes: Ed25519 (parallel verification) and BLS12-381 (aggregation)
• Configurable workers, batching, and adaptive pacing
• Generic design supporting custom hash and transaction types
• Epoch-based reconfiguration for validator set changes
• Comprehensive observability hooks for metrics integration

Verification

• Fault tolerance tests: crash, slow validator, Byzantine equivocation, out-of-order delivery
• Stress tests: 50K TPS sustained load, goroutine/memory leak detection, rapid start/stop cycles
• Comprehensive test suite with race detection
