- GoMining uses DMND pool to mine the first Stratum V2 Bitcoin block.
- Stratum V2 allows miners to directly select block transactions.
- The new system shifts power in Bitcoin mining from the pool to the miners.
GoMining mined the first Bitcoin block created using the Stratum V2 protocol with the DMND Bitcoin mining pool.
This process demonstrates miner-controlled block generation in a real mining environment.
Blocks were generated using Stratum V2’s job declaration feature via the DMND pool.
This approach allowed GoMining to construct and declare its own block templates rather than relying on mining pools to select transactions.
Pool-controlled transaction selection has been the dominant model of Bitcoin mining for many years.
This milestone represents the initial real-world implementation of Stratum V2’s miner-centric architecture and highlights the shift toward giving miners greater control over how blocks are constructed while retaining some of the collaborative mining operations.
Miner-controlled block configuration demonstrated in production
The block included transactions linked to GoMining’s GoBTC Pay, an open-source Bitcoin instant payment protocol developed by the company.
By incorporating GoBTC Pay transactions into generated block templates, GoMining demonstrated a real-world use case for Stratum V2’s declaration of work feature and demonstrated how miners can directly influence the content of the blocks they help create.
“This block shows that miners can now participate in collaborative mining while retaining control over block creation,” said Mark Zalan, CEO of GoMining. “For years, mining pools have largely determined which transactions are included in a Bitcoin block. By creating our own block templates and including GoBTC Pay transactions, we are demonstrating one of the practical features that Stratum V2 enables.”
The successful mining of a block provides an example of how miners can gain more autonomy while continuing to benefit from shared resources and the 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 several participants in the Bitcoin industry.
In addition to improving security and efficiency, this protocol allows miners to create their own block templates while still participating in communal mining.
The latest development shows that miner-controlled block composition can operate in a production environment and could potentially support widespread adoption of Stratum V2 across the mining ecosystem.
The deployment also demonstrates how the protocol allows miners to integrate their own applications and services directly into the block generation process.
“A miner just mined the first Stratum V2 block, powering his product end-to-end. GoMining declared the template and included GoBTC Pay payments without a pool. We built DMND for exactly that.” Alejandro De La Torre, CEO and co-founder of DMND, said:
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 maintaining 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.
