- GoMining mines first Stratum V2 Bitcoin block with DMND pool.
- Stratum V2 enables miners to choose block transactions directly.
- New system shifts power from pools to miners in Bitcoin mining.
GoMining has mined the first known Bitcoin block produced using the Stratum V2 protocol with the DMND Bitcoin mining pool.
The process demonstrates miner-controlled block creation in a live mining environment.
The block was created using Stratum V2’s Job Declaration functionality through the DMND pool.
The approach allowed GoMining to construct and declare its own block template rather than relying on a mining pool to select transactions.
Pool-controlled transaction selection has been the dominant model in Bitcoin mining for years.
The milestone marks an early real-world implementation of Stratum V2’s miner-driven architecture and highlights a shift toward giving miners greater authority over how blocks are constructed while remaining part of pooled mining operations.
Miner-controlled block construction demonstrated in production
The block included transactions linked to GoMining’s GoBTC Pay, an open-source Bitcoin instant payments protocol developed by the company.
By incorporating GoBTC Pay transactions into the block template it created, GoMining demonstrated a practical use case for Stratum V2’s Job Declaration feature and showed how miners can directly influence the contents of blocks they help produce.
“This block demonstrates that miners can now participate in pooled mining while retaining control over block construction,” said Mark Zalan, CEO at 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.”
The successful mining of the block provides an example of how miners may be able to gain more autonomy while continuing to benefit from the shared resources and economics of mining pools.
Stratum V2 aims to expand miner participation and flexibility
Stratum V2 is an open-source mining protocol developed with contributions from multiple participants across the Bitcoin industry.
In addition to improvements in security and efficiency, the protocol enables miners to create their own block templates while still participating in pooled mining.
The latest development demonstrates that miner-controlled block construction can operate in a production environment, potentially supporting broader adoption of Stratum V2 across the mining ecosystem.
The deployment also illustrates how the protocol may allow miners to integrate their own applications and services directly into the block creation process.
“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.” said Alejandro De La Torre, CEO & Co-founder at DMND.
The milestone comes as the bitcoin mining industry continues to explore technologies that improve efficiency, security and decentralization.
By demonstrating that miners can build and declare their own block templates while remaining part of a mining pool, GoMining and DMND have provided an early example of how Stratum V2’s architecture could reshape block creation and transaction selection within the broader Bitcoin mining ecosystem.
