It's a mechanism by which miners trigger
activation of soft forks when a majority signals the readiness to upgrade.
While Litecoin inventor Charlie Lee has been advocating for
activation of the soft fork since late 2016, miner support initially did not follow.
The other tradeoff is that the method allows a small number of hash power to veto
activation of the soft fork for everyone on the network.
Not exact matches
Instead
of hash power
activation, a user activated
soft fork would have a ««flag day
activation» where nodes begin enforcement at a predetermined time in the future.»
Over the past couple
of years,
soft forks were mostly implemented by hash power
activation.
The timeline for that support will be driven by the
activation of the required
soft fork,» Pair said, «but we don't know exactly when the
activation will occur, so we don't want to spend time now only to have it take another six months or a year before
activation happens.»
Who Supports UASF Lately, there has been a lot
of talk regarding the possible
activation of a User Activated
Soft Fork (UASF) in order to implement the SegWit proposal without the need to reach miner consensus.
An initiative by Digital Currency Group CEO Barry Silbert, the project — later dubbed «SegWit2x» — was to combine
activation of the Segregated Witness
soft fork with a hard
fork to double Bitcoin's block weight limit.
It's a mechanism where the
activation time
of a
soft fork occurs on a specified date enforced by full nodes, a concept sometimes referred to as the economic majority.
Prior to the
activation of the Segregated Witness
soft fork in August 2017, there were concerns about the scalability and malleability
of Bitcoin due to the size limit
of the blocks and a potential manipulation
of the transaction ID.
As tensions resulting from Bitcoin Unlimited's growing dominance started to boil over, two further proposals soon emerged that has today taken center stage in the scaling debate: a user - activated
soft fork for the «mandatory
activation of segwit deployment» as specified in BIP148, and SegWit2x.
August 1st is also the scheduled
activation of BIP 148, also known as the User Activated
Soft Fork (UASF).
