Foundry USA Pool has begun testing Stratum V2. The question for Bitcoin mining is who gets to choose the transactions in a block: the pool operator or the miners providing the computing power.
Under the arrangement described by Odaily, pools have typically held more of that control. Stratum V2 allows individual miners to build block templates and choose transactions themselves. Odaily also says the protocol introduces encrypted communication and could reduce bandwidth use by up to approximately 70%, improving mining efficiency and communication security.
Odaily reports that Foundry and AntPool are gradually moving toward adoption. The potential benefit is less concentrated control over transaction selection without changing the distribution of network computing power. But Foundry’s test is not the same as broad adoption, and the report does not establish how much control miners will exercise in practice.
