Bitcoin breaking news: Seven major Bitcoin mining pools—Antpool, F2Pool, Foundry, Spiderpool, Block, MARA Foundation, and DMND—have joined the Stratum V2 working group. The new protocol enables miners to construct their own block templates and incorporates end-to-end encryption. It reduces bandwidth usage by 60–70% and decreases the risk of hash rate hijacking. Testing indicates miner revenue could increase by up to 7.4%. Bitcoin news outlets such as ChainCatcher reported this development.

ChainCatcher report: Seven major Bitcoin mining pools—Antpool, F2Pool, Foundry, Spiderpool, Block, MARA Foundation, and DMND—have officially joined the Stratum V2 Working Group, signaling a accelerated shift toward the next-generation open-source protocol in Bitcoin mining. Unlike the current V1 version, where mining pools control transaction packaging, Stratum V2 introduces end-to-end encryption, reducing bandwidth usage (by 60% on the pool side and 70% on the miner side) and mitigating hashrate hijacking risks, while also allowing miners to construct their own block templates. Testing shows that Stratum V2 can increase miner earnings by up to 7.4% through lower latency and improved fee selection.
