“Furthermore, there are developments such as Stratum [version]2 that would, among other things, empower individual miners to construct block templates, taking that power away from mining pools,” he added. Stratum V2 is a new bitcoin mining protocol that is being developed, improving on many aspects of the previous version, Stratum V1, which miners use to communicate with the mining pools. The improvements include more efficient data transfer and protections against network centralization.
