Bitcoin mining pool Demand It mined the first known Bitcoin block produced using the Stratum V2 protocol, a technical breakthrough that transfers control of block construction from pools to individual miners. The block — No. 955,318 — was mined through GoMining’s DMND pool, which became the first miner to use Stratum V2’s job declaration feature to define its own transactions and create its own block template, according to a note shared with Bitcoin Magazine.
Under the prevailing model of Bitcoin mining today, miners contribute their computing power to a pool, and the pool decides which transactions will go into each block. The miner has no say in this choice.
Layer V2, open source protocol Developed with broad industry support, it changes this arrangement. It allows miners to retain their participation in pooled mining – smoothing out revenue disparity – while regaining the right to create the block template themselves. The job declaration is the specific mechanism that makes this possible: the miner submits his proposed block template to the pool, the pool validates it, and the miner copy moves forward.
GoMining used this mechanism to include transactions from GoBTC paymentan open source, non-custodial, instant Bitcoin payments protocol that the company announced at the Miami Consensus Conference in May 2026. The result is the first known instance of a miner using Stratum V2 in a live production environment to run his own product through a block he helped create.
“One miner mined the first Stratum V2 block to run their own product from start to finish,” said Alejandro de la Torre, CEO and co-founder of DMND. “GoMining announced the model and listed its GoBTC Pay payments without any pooling in the way. We created DMND for exactly this purpose.”
Mark Zalan, CEO of GoMining, frames the importance in structural terms. “For many years, mining pools have determined the transactions embedded in Bitcoin blocks,” he said. “By being the first to announce our block template and include GoBTC Pay transactions, we are demonstrating one of the practical capabilities that Stratum V2 enables.”
Bitcoin miners gain control over transactions
The effects extend beyond this single block. Mining pool transaction selection has been a long-standing concern in Bitcoin, both to resist censorship and to distribute power across the network’s transaction layer.
If Stratum V2 adoption increases, miners — not pools — become the decision makers on what goes into the blockchain. The production deployment of DMND demonstrates that the protocol can work in a live environment, removing one barrier to this broader adoption.
GoMining, which serves five million users and ranks among the top ten Bitcoin miners by hash rate, operates data centers in the United States and internationally.
The company offers retail token products along with its own payment and earning tools. DMND describes itself as a suite designed for the Stratum V2 era, with the job posting running in production.
