GoMining has achieved a milestone in Bitcoin mining by producing what it claims is the first block mined using the Stratum V2 protocol through the DMND mining pool. The event, announced on June 25, 2026, demonstrates how miners can now build and declare their own block templates while still participating in pooled mining.
How Stratum V2 Changes Block Construction
Traditionally, mining pools have controlled which transactions are included in Bitcoin blocks. Stratum V2's Job Declaration feature shifts this power to individual miners, allowing them to construct their own block templates. In this case, GoMining built its own template and submitted it to the DMND pool, which then mined the block. The block included transactions linked to GoBTC Pay, an open-source Bitcoin instant payments protocol developed by GoMining.
“This block demonstrates that miners can now participate in pooled mining while retaining control over block construction,” said Mark Zalan, CEO of GoMining. “For years, mining pools have largely determined which transactions are included in Bitcoin blocks. By creating our own block template and including GoBTC Pay transactions, we're demonstrating one of the practical capabilities that Stratum V2 makes possible.”
Implications for the Mining Ecosystem
Stratum V2 is an open-source protocol developed with contributions from various Bitcoin industry participants. Beyond improving security and efficiency, it enables miners to create their own block templates while still benefiting from the stability and rewards of pooled mining. This milestone shows that miner-controlled block construction can function in a live production environment, which could encourage broader adoption of Stratum V2 across the Bitcoin mining ecosystem.
Alejandro De La Torre, CEO and Co-founder of DMND, commented: “A miner just mined the first Stratum V2 block to power their own product end to end. GoMining declared the template and included their GoBTC Pay payments with no pool in the way. We built DMND for exactly this.”
This development comes amid broader shifts in the mining landscape. For context, JPMorgan Warns of Bitcoin Risk as Miner Revenue Drops to 2022 Lows, highlighting the financial pressures miners face. Meanwhile, traditional finance is also exploring blockchain technology, as seen in JPMorgan, Citi, BofA to Launch Shared Blockchain Deposit Network by 2027.
Real-World Use Case for Miner-Driven Architecture
GoMining's successful block demonstrates a practical application of Stratum V2's miner-driven architecture. By including GoBTC Pay transactions, the company showcased how miners can directly support their own payment protocols without pool interference. This could pave the way for more innovative use cases where miners have greater autonomy over block content.
The milestone also highlights the growing importance of protocols that decentralize control within Bitcoin mining. As the industry evolves, tools like Stratum V2 may help miners differentiate their operations and potentially improve profitability by selecting transactions that align with their business models.
