Bitcoin mining pool DMND has mined the primary identified Bitcoin block produced utilizing the Stratum V2 protocol, a technical milestone that shifts management over block building from swimming pools to particular person miners. The block — quantity 955,318 — was mined via DMND’s pool for GoMining, which grew to become the primary miner to make use of Stratum V2’s Job Declaration function to pick its personal transactions and construct its personal block template, in accordance with a be aware shared with Bitcoin Journal.
Beneath the dominant mannequin in Bitcoin mining immediately, miners contribute their computing energy to a pool, and the pool decides which transactions go into every block. The miner has no say in that choice.
Stratum V2, an open-source protocol developed with broad business help, modifications this association. It permits miners to retain their participation in pooled mining — which smooths out income variance — whereas taking again the appropriate to assemble the block template themselves. Job Declaration is the particular mechanism that makes this potential: a miner submits its personal proposed block template to the pool, the pool validates it, and the miner’s model goes ahead.
GoMining used that mechanism to incorporate transactions from GoBTC Pay, an open-source, non-custodial Bitcoin prompt funds protocol the corporate introduced at Consensus Miami in Might 2026. The result’s the primary identified case of a miner utilizing Stratum V2 in a stay manufacturing surroundings to energy its personal product via the block it helped create.
“A miner simply mined the primary Stratum V2 block to energy their very own product finish to finish,” stated Alejandro De La Torre, CEO and co-founder of DMND. “GoMining declared the template and included their GoBTC Pay funds with no pool in the best way. We constructed DMND for precisely this.”
GoMining CEO Mark Zalan framed the importance in structural phrases. “For years, mining swimming pools have decided which transactions are included in Bitcoin blocks,” he stated. “By being the primary to declare our personal block template and embrace GoBTC Pay transactions, we’re demonstrating one of many sensible capabilities that Stratum V2 makes potential.”
Bitcoin miners acquire transaction management
The implications lengthen past this single block. Mining pool transaction choice has been a long-standing concern in Bitcoin, each for censorship resistance and for the distribution of energy over the community’s transaction layer.
If Stratum V2 adoption grows, miners — not swimming pools — develop into the decision-makers on what enters the blockchain. DMND’s manufacturing deployment exhibits the protocol can operate in a stay surroundings, which removes one barrier to that broader adoption.
GoMining, which serves 5 million customers and ranks among the many top-ten Bitcoin miners by hashrate, operates information facilities within the U.S. and internationally.
The corporate presents tokenized hashrate merchandise alongside its funds and incomes instruments. DMND describes itself as a pool constructed for the Stratum V2 period, with Job Declaration operating in manufacturing.
