GoMining will use the DMND pool to mine the first Stratum V2 Bitcoin block. Stratum V2 allows miners to directly select block transactions. The new system transfers power in Bitcoin mining from pools to miners.
GoMining has mined the first known Bitcoin block produced using the Stratum V2 protocol in the DMND Bitcoin mining pool.
This process shows the creation of blocks controlled by miners in a real mining environment.
This block was created through the DMND pool using Stratum V2’s job declaration feature.
This approach allows GoMining to build and declare its own block templates, rather than relying on mining pools to select transactions.
Pool-managed transaction selection has been the dominant model for Bitcoin mining for many years.
This milestone marks an early real-world implementation of Stratum V2’s miner-driven architecture and highlights a move toward giving miners greater power over how blocks are constructed while retaining some of the pooled mining operations.
Miner-controlled block construction proven in production
This block included transactions linked to GoBTC Pay, an open-source Bitcoin instant payment protocol developed by GoMining.
GoMining demonstrated a practical use case for Stratum V2’s job declaration feature by incorporating GoBTC Pay transactions into the block templates it created, showing how miners can directly influence the content of the blocks they help generate.
“This block demonstrates that miners can participate in pooled mining while maintaining control over block construction,” said GoMining CEO Mark Zalan. “For years, mining pools have largely determined which transactions are included in a Bitcoin block. By creating their own block templates and including GoBTC Pay transactions, we are demonstrating one of the practical features that Stratum V2 enables.”
The successful mining of blocks provides an example of how miners can gain more autonomy while continuing to benefit from the shared resources and economics of a mining pool.
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 improving security and efficiency, this protocol allows miners to create their own block templates while participating in pooled mining.
The latest development demonstrates that miner-controlled block construction can work in production, potentially supporting widespread adoption of Stratum V2 across the mining ecosystem.
This deployment also shows how the protocol allows miners to directly integrate their applications and services into the block creation process.
“Miners just mined the first Stratum V2 block to power their own products end-to-end. GoMining declared a template and incorporated GoBTC Pay payments without a pool. We built DMND for exactly this.” said Alejandro De La Torre, CEO and Co-Founder of DMND.
This 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 the mining pool, GoMining and DMND provided an early example of how Stratum V2’s architecture can reshape block creation and transaction selection within the broader Bitcoin mining ecosystem.
