Chia-Network/chia-blockchain
Chia Blockchain
Chia is a decentralized blockchain platform that uses a proof-of-space-and-time consensus mechanism, enabling energy-efficient farming on commodity hardware. It implements a full blockchain node, farmer, harvester, timelord, and wallet in Python, prioritizing readability and cross-platform compatibility. The platform manages transactions through a simplified UTXO model that minimizes on-chain state and supports fast validation.
The project introduces Chialisp, a Turing-complete functional smart contract language designed for secure and auditable financial transactions. It features a pooling protocol that allows farmers to participate in mining pools while retaining control over block creation, preventing pool centralization. Aggregate BLS signatures per block reduce on-chain data and verification costs, while an objective light client syncing protocol enables lightweight clients to quickly verify blockchain state without downloading the full chain.
The platform provides tools for running a full node with both graphical and command-line interfaces, managing wallets and transactions, farming blocks in pools with farmer control, and writing smart contracts in Chialisp. The documentation and installation surface covers full node operation, wallet management, farming setup, and smart contract development through both GUI and CLI interfaces.
