BlockBeats News, May 10th, the seven major Bitcoin mining pools - Antpool, F2Pool, Foundry, Spiderpool, Block, MARA Foundation, and DMND - have officially joined the Stratum V2 working group, marking a significant step towards the next generation open-source protocol for Bitcoin mining.

Reportedly, compared to the current V1 version where transaction batching is controlled by the pools, Stratum V2 introduces end-to-end encryption. This not only reduces bandwidth usage (60% reduction on the pool side and 70% reduction on the miner side) and the risk of hashrate hijacking, but also allows miners to construct their own block templates. Tests have shown that with lower latency and improved fee selection, the V2 protocol can increase miner revenue by up to 7.4%. (Bitcoin com)
