A newly mined Bitcoin block showcases how Stratum V2 could shift control over transaction selection away from mining pools and back to individual miners.
The balance of power in Bitcoin mining may be starting to shift.
GoMining announced it has mined what it describes as the first known Bitcoin block using Stratum V2’s Job Declaration feature, a capability that allows miners to assemble their own block templates while remaining part of a mining pool. The block was produced through the DMND mining pool and included transactions generated by GoBTC Pay, GoMining’s open-source Bitcoin payments protocol.
The development is significant because mining pools have historically decided which transactions are included in blocks, even though individual miners contribute the computing power. Stratum V2 was created to change that dynamic by separating hash power from block construction.
“This block demonstrates that miners can now participate in pooled mining while retaining control over block construction,” said GoMining CEO Mark Zalan. “By creating our own block template and including GoBTC Pay transactions, we’re demonstrating one of the practical capabilities that Stratum V2 makes possible.”
The protocol has been under development for years by contributors across the Bitcoin ecosystem and introduces several upgrades beyond miner-selected templates, including enhanced communication security and greater operational efficiency. Advocates believe widespread adoption could make Bitcoin mining less dependent on a handful of large pool operators.
For DMND, which partnered with GoMining on the milestone, the successful block represents proof that the protocol can function in a live production environment.
“A miner just mined the first Stratum V2 block to power their own product end to end,” said Alejandro De La Torre, CEO and co-founder of DMND. “GoMining declared the template and included their GoBTC Pay payments with no pool in the way.”
While the mining announcement centers on Bitcoin’s infrastructure, GoMining is also expanding the commercial side of its ecosystem.
The company recently launched a “Step Down Auction” system for its secondary marketplace, introducing automated price reductions for Digital Miner sales. Rather than requiring buyers to submit bids, sellers establish a starting and minimum price, with listings automatically decreasing in value until purchased.
The marketplace overhaul also adds public browsing of listings, ROI statistics, price history, and enhanced search filters intended to improve liquidity and transparency.
Together, the two initiatives illustrate different parts of GoMining’s strategy. One focuses on advancing Bitcoin’s underlying mining architecture by giving miners greater autonomy, while the other seeks to simplify how users buy and sell tokenized mining assets.
Whether Stratum V2 becomes an industry standard remains an open question. But as more mining companies experiment with miner-controlled block construction, the protocol is beginning to move beyond theory and into practical deployment, offering a glimpse of how Bitcoin mining infrastructure could evolve in the years ahead.
