Seven major Bitcoin mining pools representing about 75% of network hashrate have joined the Stratum V2 working group, backing a protocol that shifts block template control from pools toward individual miners.
The official Stratum V2 protocol blog (stratumprotocol.org/blog/new-members/) is the primary authoritative source and directly confirms all core elements of the claim: seven participants joined, and the named pools (Foundry, AntPool, F2Pool, SpiderPool, MARA Foundation/MARA Pool) are all listed. CoinDesk corroborates the ~75% global hashrate figure with individual pool breakdowns summing to approximately that figure. The claim's description of the protocol shifting block template construction toward individual miners is confirmed by all three sources. The only minor imprecision is that the entity is 'MARA Foundation' rather than 'MARA Pool' specifically, and the seventh pool is 'Block Inc.' alongside DMND — details the claim omits but does not contradict. The nearly three-quarters hashrate figure is accurate per CoinDesk's data.
Seven of the world’s largest Bitcoin mining pools have joined the Stratum V2 Working Group, bringing the open protocol’s backing to roughly 75% of Bitcoin network hashrate. The group includes Foundry, AntPool, F2Pool, SpiderPool and MARA Pool among the seven participants. Stratum V2 is designed to improve communication between miners and pool operators while moving block template construction away from pool-level control and toward individual miners, a change that could alter how mining coordination and block creation decisions are distributed across the network.
