Bitcoin XT

Bitcoin XT is a Bitcoin client that differs from the core specifications. The basis of Bitcoin XT is the increase of maximum block sizes as described in BIP101, among other changes.

BitcoinXT is not compatible with the existing BitcoinQT core system. If, for example, you use XT, it will branch off into a "hard fork" that is separate from the blockchain used to this point.
