A user activated soft fork (UASF, or user-activated soft fork), in the context of bitcoin, was a plan to activate a bitcoin soft fork on a specified date and enforced by a majority of full nodes rather than relying on miners. In order to succeed, participating nodes must have represented a so-called "economic majority" - users, exchanges and businesses with significant influence over the bitcoin economy. A UASF requires developer, industry and user coordination. In the past, a UASF was successfully carried out to activate the P2SH soft fork (aka BIP16). On Feb 25, 2017, a pseudonymous contributor named Shaolin Fry proposed that UASF be used to activate Segregated Witness and later published details in BIP148.
