In what represents a watershed moment for Bitcoin's mining infrastructure, DMND mining pool has successfully mined the first known block using the Stratum V2 protocol's Job Declaration feature. Block number 955,318 marks a fundamental shift in how transaction selection operates within the world's largest cryptocurrency network, potentially redistributing power from centralized pool operators back to individual miners.
The achievement, accomplished in partnership with GoMining, demonstrates that Stratum V2 can function effectively in live production environments. More significantly, it proves that miners can now construct their own block templates while still benefiting from the revenue stability that pooled mining provides. This development addresses longstanding concerns about centralization and censorship resistance in Bitcoin's transaction layer.
Understanding the Stratum V2 Protocol Revolution
For over a decade, Bitcoin mining has operated under a model where pool operators wielded significant control over transaction selection. When miners contribute their computational power to a pool, they traditionally surrender any influence over which transactions ultimately get included in blocks. The pool operator makes these decisions unilaterally, creating a concentration of power that runs counter to Bitcoin's decentralized ethos.
Stratum V2 fundamentally restructures this relationship. Developed as an open-source protocol with extensive industry collaboration, it introduces the Job Declaration mechanism that empowers individual miners to submit their own proposed block templates. The pool validates these submissions, but the miner's transaction selections proceed rather than the pool's preferences.
This technical innovation preserves the economic benefits of pooled mining, which smooths out the variance in mining revenue, while restoring transaction selection authority to miners themselves. The implications for network decentralization are substantial, as transaction inclusion becomes a distributed decision rather than one concentrated among a handful of major pool operators.
GoMining's Historic Block Template Achievement
GoMining, a company serving approximately five million users and ranking among the top ten Bitcoin miners by hashrate, became the first entity to successfully deploy Stratum V2's Job Declaration feature in a production environment. The company operates data centers across the United States and internationally, giving it the scale necessary to test this groundbreaking protocol.
What makes this particular block especially noteworthy is that GoMining used its newfound transaction selection capability to include transactions from GoBTC Pay, an open-source, non-custodial Bitcoin instant payments protocol the company unveiled at Consensus Miami in May 2026. This represents the first instance of a miner using Stratum V2 to directly power its own product through a block it helped create.
Mark Zalan, CEO of GoMining, emphasized the structural significance of this achievement. The company demonstrated that Stratum V2 enables miners to exercise practical control over block contents, a capability that was previously theoretical but is now proven in live operation. By including GoBTC Pay transactions in their self-declared template, GoMining showed that this technology can serve real commercial applications.
DMND CEO and co-founder Alejandro De La Torre highlighted the seamless integration of the entire process. GoMining declared its own template and included its payment protocol transactions without pool interference, exactly the use case DMND was designed to facilitate. The pool positions itself as purpose-built for the Stratum V2 era, with Job Declaration running in full production.
Implications for Bitcoin Mining Decentralization
The successful deployment of Stratum V2 with Job Declaration addresses one of Bitcoin's most persistent centralization concerns. Mining pool transaction selection has long represented a vulnerability in the network's censorship resistance properties. A small number of large pools have historically controlled which transactions enter blocks, creating potential single points of failure or coercion.
With this new paradigm, the decision-making power over blockchain entries shifts to miners themselves. If Stratum V2 adoption accelerates following this proof of concept, the network could see a fundamental restructuring of its transaction layer governance. Pools would retain their role in coordinating mining efforts and distributing rewards, but would lose their gatekeeping function over transaction inclusion.
This redistribution of power matters particularly in an era of increasing regulatory scrutiny over cryptocurrency infrastructure. When pools control transaction selection, they become natural targets for governments seeking to impose compliance requirements or censorship demands. Distributing this function across thousands of individual miners makes such control significantly more difficult to achieve.
The technical validation provided by block 955,318 removes a major barrier to broader Stratum V2 adoption. Mining operations considering the protocol transition now have evidence that it functions reliably in production, reducing the perceived risk of implementation.
DMND Pool's Strategic Position in the Stratum V2 Era
DMND has positioned itself as the infrastructure provider for this new mining paradigm. The pool achieved SOC 2 compliance and opened its services to all miners in late 2025, building the foundation for this milestone achievement. Its architecture was specifically designed to support Stratum V2's advanced features, including Job Declaration in full production mode.
The pool's approach represents a philosophical departure from traditional mining pool business models. Rather than viewing transaction selection as a valuable control point to be retained, DMND treats miner autonomy as a competitive advantage. This positions the pool favorably as the industry increasingly recognizes the importance of decentralized transaction selection.
For miners evaluating pool options, the ability to construct their own block templates may become a decisive factor. Operations concerned about regulatory exposure or censorship resistance now have a concrete option for maintaining control over their mining activities while still benefiting from pooled revenue distribution.
What This Means for Bitcoin's Future Infrastructure
The successful Stratum V2 deployment arrives at a critical juncture for Bitcoin infrastructure development. As the network matures and faces growing institutional and regulatory attention, the distribution of power among its stakeholders becomes increasingly consequential. This achievement demonstrates that technical solutions can address centralization concerns without sacrificing operational efficiency.
GoMining's integration of GoBTC Pay transactions into its self-declared block template illustrates another dimension of this advancement. Mining operations can now build vertical integration strategies that encompass transaction processing, block construction, and related services. This capability opens new business model possibilities for sophisticated mining enterprises.
The path forward likely depends on broader industry adoption of Stratum V2. Other major pools will face pressure to offer similar capabilities or risk losing miners who prioritize autonomy. Hardware manufacturers may also integrate Stratum V2 support more deeply into their products, further accelerating adoption.
Industry observers should monitor whether additional pools implement Job Declaration features and whether miners increasingly demand this functionality. The competitive dynamics of the mining pool market could shift significantly if transaction selection autonomy becomes a standard expectation rather than a novel feature.
Outlook for Stratum V2 Adoption
Block 955,318 represents proof of concept, but the real test lies ahead. The Bitcoin mining industry moves deliberately, and widespread protocol changes typically require years of gradual adoption. However, the successful production deployment by two significant industry players provides momentum that previous theoretical discussions lacked.
GoMining's scale and DMND's purpose-built infrastructure suggest that further Stratum V2 blocks will follow. As more miners experience the benefits of template construction autonomy, demand for this capability should increase across the broader mining ecosystem. The question is no longer whether Stratum V2 works, but how quickly the industry embraces its implications.
For Bitcoin as a network, this development strengthens its foundational promise of decentralization. Transaction selection distributed across miners rather than concentrated among pools creates a more resilient and censorship-resistant system. This milestone may eventually be remembered as the moment when Bitcoin's mining layer began its most significant structural evolution since the emergence of pooled mining itself.
