Architecture
Design Overview
Key technical decisions behind QryptCoin's settlement layer
Ledger & Consensus
Double-SHA-256 proof-of-work over 80-byte block headers. UTXO model for ownership. Chainwork-based tip selection. 600-second target block interval. Difficulty adjusts every 2,016 blocks. Witness commitment (QRYW 0x01) required in non-genesis blocks.
Post-Quantum Authorization
ML-DSA-65 (FIPS 204) signatures authorize spends. Outputs commit to SHA3-256(REVEAL_V1); public keys revealed only at spend time. Consensus enforces one-time keys: each pk_hash may appear at most once on the active chain.
Transport Security
Optional post-quantum encrypted P2P transport (ML-KEM-768 + ChaCha20-Poly1305). Provides confidentiality against network adversaries. Does not affect consensus; does not provide anonymity.
For Operators
JSON-RPC Interface
The reference node exposes a JSON-RPC interface for querying chain state, managing peers, monitoring mempool, and controlling mining workflows.
Blockchain Queries
Get block info, chain tips, difficulty, and sync status.
Network & Peers
Manage peer connections and network info.
Wallet Operations
Create transactions, manage addresses, query balances.
Documentation
RPC method documentation is published with the source repository and release notes.
