What is it?

Chia is a cryptocurrency that uses proof of space and time consensus instead of proof of work, so that farmers can take part with commodity hardware. This repository is the reference Python implementation of the network, bundling the full node, farmer, harvester, timelord, and wallet into one codebase with both a GUI and a command-line interface.

The project uses a simplified UTXO transaction model with small on-chain state, a Lisp-style functional language (Chialisp) for transaction logic, and BLS keys with aggregate signatures so each block carries one signature. It also includes a built-in DNS seeder that maintains a list of reliable nodes, and a pooling protocol that lets farmers keep control over block creation. Light clients are supported with fast, objective syncing.

Python 3.11 or newer is required. Most users only need to run harvesters, farmers, plotters, full nodes and wallets, while running timelords or VDFs is aimed at advanced operators.

Key features

  • 01Proof of space and time consensus that lets anyone farm with commodity hardware
  • 02Full node, farmer, harvester, timelord and wallet in one codebase
  • 03Built-in DNS seeder that maintains a list of reliable peers
  • 04Simplified UTXO transaction model with Chialisp for transaction logic
  • 05BLS keys with aggregate signatures and a pooling protocol
  • 06Light client support with fast syncing

Use cases

  • Running a home farm with harvesters and a farmer on commodity hardware
  • Operating a full node to validate the Chia network
  • Managing XCH funds with the built-in wallet
  • Joining a farming pool while keeping control over block creation

Quick start

Things to know

  • Requires Python 3.11 or newer.
  • Peers behind a NAT need UPnP or manual router and firewall setup to open TCP port 8444.
