About Bitcoin ABC

Bitcoin ABC is a full-node software implementation of the eCash (XEC) protocol, a Layer 1 blockchain derived from Bitcoin designed for peer-to-peer electronic cash transactions. The project develops core protocol specifications and maintains the reference node software. The architecture combines a Nakamoto consensus base layer with an Avalanche pre-consensus layer that enables transaction finality without extended confirmation periods. Bitcoin ABC distributes reference node software, an Electrum-compatible light wallet, and technical documentation for node operators, miners, and developers. The project operates as an open-source infrastructure organization without custodial functions. Development began in 2017 and continues under the eCash protocol framework.
