Bitcoin Mining Pool DMND Mined the first Bitcoin block using the Stratum V2 Protocol, a technological milestone which shifts the control of block construction away from pools and towards individual miners. The block — number 955,318 — was mined through DMND’s pool for GoMining, which became the first miner to use Stratum V2’s Job Declaration feature to select its own transactions and build its own block template, according to a note shared with Bitcoin Magazine.
The dominant Bitcoin mining model today is that miners give their computing power into a pool and then the pool determines what transactions will be included in each Bitcoin block. This selection is made by the pool, not by the miner.
Stratum V2, a free open-source protocol The new arrangement, developed with the support of a broad sector, is a change. It allows miners to retain their participation in pooled mining — which smooths out revenue variance — while taking back the right to construct the block template themselves. The Job Declaration mechanism is what makes it possible. A miner can submit its block template proposal to the pool.
GoMining includes transactions that are made through this method. GoBTC PayIn May 2026, the company launched a non-custodial, open-source Bitcoin instant payment protocol. This is the first time a miner has used Stratum V2 to run its product in a production environment.
“A miner just mined the first Stratum V2 block to power their own product end to end,” Alejandro De La Torre is the CEO and founder of DMND. “GoMining declared the template and included their GoBTC Pay payments with no pool in the way. We built DMND for exactly this.”
Mark Zalan of GoMining laid out the structural significance. “For years, mining pools have determined which transactions are included in Bitcoin blocks,” He said. “By being the first to declare our own block template and include GoBTC Pay transactions, we’re demonstrating one of the practical capabilities that Stratum V2 makes possible.”
Bitcoin Miners Gain Transaction Control
This block has implications that go beyond it. Bitcoin’s mining pool selection is a concern that has existed for many years, for both the resistance to censorship and the distribution of the power in the network transaction layer.
If Stratum V2 adoption grows, miners — not pools — become the decision-makers on what enters the blockchain. DMND’s production deployment has shown that the protocol is capable of functioning in a real-world environment. This removes a barrier for broader adoption.
GoMining is one of the world’s top Bitcoin mining companies, with over five million users. They have data centers located in both the U.S.A. and around the globe.
In addition to its earning and payment tools, Hashrate offers tokenized versions of the product. DMND calls itself a pool designed for the Stratum V2 era with Job Declaration in production.
