UASF - Bitcoin’s emergency plan to enact SegWit
A full year after the code was released, Segregated Witness (SegWit) still has little chance of being adopted by Bitcoin miners. The Bitcoin Improvement Proposal (BIP) includes a wide range of features, including larger block sizes.
The backward-compatible soft fork requires a majority of miners to enforce the new rules. Between 25 and 40 percent of miners are signalling for the change, while 95 percent is required for SegWit adoption.
