What is Bitcoin Cash?

Bitcoin Cash is an experimental new digital currency that enables instant payments to anyone, anywhere in the world. Bitcoin Cash uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Bitcoin Unlimited is the name of open source software which enables the use of this currency.

For more information, as well as an immediately useable, binary version of the Bitcoin Unlimited software, see https://www.bitcoinunlimited.info/download, or read the original whitepaper.

What is Bitcoin Unlimited?

Bitcoin Unlimited is an implementation of the Bitcoin client software that is based on Bitcoin Core. However, Bitcoin Unlimited has a very different philosophy than Core.

It follows a philosophy and is administered by a formal process described in the Articles of Federation. In short, we believe in market-driven decision making, emergent consensus, and giving our users choices.
