DMND Mining Pool and GoMining Achieve Historic Stratum V2 Milestone with First Known Job Declaration Block

In a landmark moment for Bitcoin mining decentralization, the DMND mining pool has successfully produced the first known Bitcoin block built using the Stratum V2 protocol's Job Declaration feature. Block number 955,318 was mined through DMND on behalf of GoMining, marking the first time a miner — rather than a pool — took full control over transaction selection and block template construction in a live production setting.

Traditionally, Bitcoin mining pools have held exclusive authority over which transactions are bundled into each block. Individual miners contribute their hashing power to the pool but surrender all say over the contents of the blocks they help produce. This centralized model has long raised concerns among Bitcoin advocates about censorship resistance and the concentration of decision-making power within a small number of pool operators.

Stratum V2 was developed as an open-source solution to address exactly these concerns. The protocol preserves the financial benefits of pooled mining — most notably, the smoothing of revenue variance for smaller operators — while returning template-building authority to the miners themselves. The Job Declaration mechanism sits at the heart of this shift: a participating miner proposes its own block template, submits it to the pool for validation, and upon approval, that miner-constructed version proceeds to production.

GoMining leveraged this mechanism to embed transactions from GoBTC Pay, an open-source, non-custodial Bitcoin instant payments protocol the company unveiled at Consensus Miami in May 2026. The successful block represents the first documented instance of a mining participant using Stratum V2 in a real-world environment to directly power its own product through the block it constructed.

Alejandro De La Torre, CEO and co-founder of DMND, highlighted the significance of the achievement. "A miner just mined the first Stratum V2 block to power their own product end to end," he stated. "GoMining declared the template and included their GoBTC Pay payments with no pool in the way. We built DMND for exactly this."

GoMining CEO Mark Zalan emphasized the structural importance of the development. "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."

The broader implications of this milestone reach well beyond a single block. If Stratum V2 adoption continues to expand across the industry, the power to determine what enters the Bitcoin blockchain would shift decisively from a handful of large pools to a much wider group of individual miners. DMND's live deployment demonstrates that the protocol is operationally viable, removing a key obstacle to wider implementation.

GoMining is a significant player in the Bitcoin mining space, reporting a user base of five million and ranking among the top ten Bitcoin miners globally by hashrate. The company operates data centers both within the United States and internationally, and offers tokenized hashrate products alongside its suite of payment and earnings tools. DMND positions itself as a mining pool built specifically for the Stratum V2 era, with Job Declaration already running in full production capacity.
