Foundry USA Pool has begun testing Stratum V2. The question for Bitcoin miners is who chooses the transactions proposed for a block.

Mining pools have typically held much of that choice. Stratum V2 allows individual miners to build block templates and select transactions themselves, reducing their reliance on pool operators for that decision. Odaily also reports that the protocol adds encrypted communication and could cut bandwidth use by up to about 70%.

Odaily says Foundry and AntPool are gradually moving toward adoption. The potential benefit is less transaction-selection control concentrated in large pools without changing the distribution of network hash rate. But a test is not network-wide adoption, and the report does not establish how much control miners will exercise in practice.
