ANTDChain is a high-performance Proof-of-Work Layer 1 blockchain featuring a unique Rotating King governance system. Built for speed, security, and decentralized governance, it combines Ethereum-compatible tooling with innovative economic models.
- Custom PoW Algorithm: BLAKE3 + Argon2id hybrid for ASIC resistance
- EVM Compatibility: Full Ethereum Virtual Machine support
- Lightning-Fast Sync: Optimized peer-to-peer synchronization
- Checkpoint System: Trustless bootstrapping with peer-validated checkpoints
- Database-Backed State: Persistent storage with automatic recovery
- Dynamic Royalty System: 5% of block rewards distributed to rotating kings
- Stake-Based Eligibility: 100,000 ANTD minimum stake requirement
- Automatic Rotation: Kings rotate every 100 blocks automatically
- Ineligibility Protection: Addresses below minimum stake auto-removed
- Network Consensus: King lists synchronized across all nodes
- Multi-threaded block validation
- Orphan block rejection (no orphan storage)
- Chain reorganization protection
- State trie with Merkle proofs
- Transaction pool with confirmation system
- libp2p-based networking with GossipSub
- Multi-topic pub/sub for blocks, transactions, and king events
- DHT-based peer discovery
- Rate-limited message handling
- Direct block push optimization
- CPU-mining optimized PoW
- Dynamic difficulty adjustment
- Mining templates for stratum compatibility
- Real-time hash rate monitoring
- Hierarchical Deterministic (HD) wallets
- Secure key storage with encryption
- Transaction signing with ECDSA
- Nonce management and fee calculation
- Full Ethereum-compatible API
eth_,net_,web3_namespace support- Web interface with real-time monitoring
- Health check endpoints
- Native Token: ANTD (1 ANTD = 10^18 base units)
- Block Reward: 1 ANTD + transaction fees
- Reward Distribution:
- 90% → Miner
- 5% → Main King (fixed address)
- 5% → Rotating King (eligible addresses)
- Minimum Stake: 100,000 ANTD for king eligibility
- Rotation Interval: Every 100 blocks (~50 minutes)
- Activation Delay: 2 blocks after rotation
- Go 1.21+
- GCC compiler (for CGO)
- 4GB+ RAM recommended
- 50GB+ storage for full node
