The following organizations, individuals, or pools have communicated preference for and intent to support a BIP-119 activation attempt using reasonable parameters. These “soft signals” are non-binding until an actual concrete proposal has been formed, but are useful for measuring community consensus. When a concrete proposal (e.g., parameters, binaries, etc) is launched, signatories on this list should not be considered to be supportive of that particular effort unless noted otherwise.
Open an issue or a pull request on GitHub to modify or create or modify an entry for you or your organization. All listings have been individually confirmed by Jeremy Rubin where a statement is either missing or ambiguous.
The retraction column indicates if support or dissent has changed, as well as the date of the change, and should be indicated with a new entry. The “For 2022 ST” column indicates general support for the proposal made here.

Mining Pools
note: Most miners mine via mining pools, which aggregate hash power to reduce variance in mining returns. While individual miners may also express a preference for or against a fork, pools serve as a proxy for the sentiment amongst their constituent miners, were they to misjudge they might lose hashrate.
Mining percentages were estimated as of October 7th, 2021 from recent data.
