Claude - blockchain-core

Projet

Rust workspace : blockchain core library + REST API node. Partie d'un ecosysteme de 3 repos (blockchain-core, blockchain-cli, blockchain-flutter).

Architecture

blockchain-core/  (Rust workspace)
├── core/         Library crate - blockchain primitives
│   └── src/      block, chain, wallet, transaction, mining, state, persistence, config, error
├── node/         Binary crate - axum REST API (port 3000)
│   └── src/      main, state (Arc<RwLock>), api/ (blocks, transactions, wallets, mining, chain, errors)
└── tests/        Integration tests

Decisions techniques

Account-based (HashMap<Address, Balance>), pas UTXO
SHA-256 (sha2) pour hashing
Ed25519 (ed25519-dalek) pour signatures
axum 0.8 pour l'API REST
JSON files pour persistence (pas de DB)
u64 pour montants (comme satoshis, pas de floats)

API Endpoints (port 3000)

GET /api/blocks - List blocks (paginated)
GET /api/blocks/:hash - Block by hash
POST /api/transactions - Submit signed tx
GET /api/transactions/pending - Pending pool
POST /api/wallets - Generate wallet
GET /api/wallets/:address/balance - Balance + nonce
POST /api/mine - Mine block
GET /api/mining/status - Difficulty, reward
GET /api/chain/info - Chain info
POST /api/chain/validate - Validate chain
GET /api/health - Health check

Commandes

cargo build              # Build tout
cargo test               # Tests unitaires
cargo run -p blockchain-node  # Lancer le node
cargo clippy             # Lint

Phase actuelle

Phase 1-3 complètes : core lib + node API implémentés. Prochaine étape : installer Rust, compiler, lancer les tests.
