GoMining has mined what it says is the first known Bitcoin block produced using the Stratum V2 protocol through the DMND mining pool, demonstrating miner-controlled block creation in a live mining environment.
The block was created using Stratum V2’s Job Declaration feature, which allowed GoMining to build and submit its own block template instead of relying on a mining pool to select transactions.
This differs from the model commonly used across the mining industry, where pools typically determine block composition.
The block included transactions linked to GoBTC Pay, an open-source Bitcoin instant payments protocol developed by GoMining.
According to the company, the milestone highlights a real-world use case for Stratum V2’s miner-driven architecture and represents an early implementation of technology designed to give miners greater control over block construction within the Bitcoin mining ecosystem.
“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.”
Stratum V2 is an open-source mining protocol developed with contributions from participants across the Bitcoin industry.
Alongside improvements in security and efficiency, the protocol allows miners to create their own block templates while continuing to participate in mining pools.
The successful mining of the block demonstrates that miner-controlled block construction can function in a live production environment and may contribute to wider adoption of Stratum V2 within the Bitcoin mining ecosystem.
“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.
