Abstract

Bitcoin is a distributed online payment system that organises transactions into blocks. The size of blocks is limited to 1 megabyte, which also limits the number of transactions per second that can be confirmed. This year several attempts have been made to create a fork or a split that removes this restriction. One such alternative is Bitcoin Unlimited (BTU). Proponents of BTU have suggested to use a type of majority attack to force other Bitcoin miners to adopt BTU.
