Foundry USA Pool has begun testing Stratum V2, a Bitcoin mining protocol that allows individual miners to build block templates and choose which transactions to include. That would shift some transaction-selection control from pool operators to the miners supplying hashpower.
Stratum V2 also introduces encrypted communications. According to Odaily, it can reduce bandwidth use by up to approximately 70% and improve mining communication security and efficiency. Foundry and AntPool are both moving toward adoption, but the report does not say the protocol has been fully deployed. It describes reduced concentration of transaction-selection control as a potential outcome, without a change in the distribution of network hashrate.
