GoMining Mines First Bitcoin Block Using Stratum V2 With Miner-Built Template

The company says it has mined the first known Bitcoin block using Stratum V2’s Job Declaration feature, as it also rolls out new marketplace tools for digital mining assets.

GoMining says it has mined what it believes is the first known Bitcoin block produced using the Stratum V2 protocol’s Job Declaration functionality, marking an early real-world deployment of technology designed to give miners greater control over how Bitcoin blocks are constructed.

The block was mined through the DMND bitcoin mining pool, with GoMining creating and declaring its own block template rather than relying on the mining pool to determine which transactions were included. The approach represents one of the core features of Stratum V2, an open-source mining protocol that aims to improve security, efficiency and decentralization within Bitcoin mining.

According to the company, the block included transactions associated with GoBTC Pay, GoMining’s open-source Bitcoin instant payments protocol, demonstrating that miners can include transactions tied to their own applications while continuing to participate in pooled mining.

“For years, mining pools have largely determined which transactions are included in Bitcoin blocks,” said Mark Zalan, CEO of GoMining. “By creating our own block template and including GoBTC Pay transactions, we’re demonstrating one of the practical capabilities that Stratum V2 makes possible.”

Mining pools have traditionally been responsible for constructing block templates, leaving individual miners with little influence over transaction selection despite providing the computing power. Stratum V2 introduces Job Declaration, allowing miners to build their own templates while still benefiting from pooled mining rewards.

The protocol has been under development for several years with contributions from members of the Bitcoin community. Supporters argue that broader adoption could reduce centralization among mining pools by distributing block construction decisions across participating miners.

“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. We built DMND for exactly this.”

The milestone comes as Bitcoin mining companies continue exploring new infrastructure and protocol upgrades aimed at improving network resilience and operational flexibility.

Separately, GoMining has also expanded its digital mining ecosystem with the launch of a new “Step Down Auction” feature for its secondary marketplace. The automated sales mechanism allows sellers to list Digital Miners at a starting price that gradually decreases until a buyer purchases the asset, eliminating the need for competitive bidding.

The marketplace update also broadens public access to listings, introduces additional price history and ROI metrics, and adds new sorting and filtering tools designed to improve liquidity and price discovery for digital mining assets.

Together, the announcements highlight GoMining’s dual focus on advancing Bitcoin’s underlying mining infrastructure while expanding the user experience around tokenized mining products. While the Stratum V2 milestone targets improvements at the protocol level, the marketplace enhancements are aimed at making digital mining assets easier to trade and evaluate within the company’s ecosystem.

Whether the Stratum V2 implementation accelerates adoption across the wider mining industry remains to be seen. However, successfully mining a production Bitcoin block using miner-controlled template creation provides one of the first practical demonstrations of the protocol’s capabilities outside of testing environments.
