Bitcoin Cash

Bitcoin Cash brings sound money to the world, fulfilling the original promise of Bitcoin as “Peer-to-Peer Electronic Cash”. Merchants and users are empowered with low fees and reliable confirmations. The future shines brightly with unrestricted growth, global adoption, permissionless innovation, and decentralized development.

All Bitcoin holders as of block 478558 are also owners of Bitcoin Cash. All are welcome to join the Bitcoin Cash community as we move forward in creating sound money accessible to the whole world.

New Features

  • On Chain Scalability – Bitcoin Cash follows the Nakamoto roadmap of global adoption with on-chain scaling. As a first step, the blocksize limit has been made adjustable, with an increased default of 8MB.
    New Transaction Signatures – A new SigHash type provides replay protection, improved hardware wallet security, and elimination of the quadratic hashing problem.
  • New Difficulty Adjustment Algorithm (DAA) – Responsive Proof-of-Work difficulty adjustment allows miners to migrate from the legacy Bitcoin chain as desired, while providing protection against hashrate fluctuations.
  • Decentralized Development – With multiple independent teams of developers providing software implementations, the future is secure. Bitcoin Cash is resistant to political and social attacks on protocol development. No single group or project can control it. The bitcoin-ml mailing list is a good venue for making proposals for changes that require coordination across development teams.
