GoMining has mined the first known Bitcoin block using the Stratum V2 protocol, marking a significant milestone for Bitcoin mining by demonstrating that miners can create their own block templates while continuing to participate in pooled mining.
Key Takeaways
- GoMining successfully mined the first known Bitcoin block using Stratum V2 through the DMND mining pool.
- The block was created using Job Declaration, allowing GoMining to build its own block template instead of relying on the mining pool to choose transactions.
- The block included transactions related to GoBTC Pay, showcasing a real world use case for the protocol.
- The achievement highlights how Stratum V2 could increase miner participation in block construction while supporting decentralized mining.
What Happened?
GoMining announced that it has mined the first known Bitcoin block using the Stratum V2 mining protocol through the DMND mining pool. The milestone demonstrates that miners can successfully construct and declare their own block templates in a live production environment while still benefiting from pooled mining.
The block was produced using Stratum V2’s Job Declaration functionality, allowing GoMining to independently decide which transactions to include. This represents a shift from the long standing mining model where pools are typically responsible for selecting transactions that appear in newly mined blocks.
GoMining Demonstrates Miner Controlled Block Creation
The newly mined block was created using DMND’s implementation of Stratum V2, enabling GoMining to build and submit its own block template. Rather than depending on a mining pool to assemble the block, the company retained direct control over transaction selection while contributing its computing power to a shared mining pool.
This approach is considered one of the core improvements introduced by Stratum V2, an open source mining protocol developed with support from contributors across the Bitcoin ecosystem. Along with improvements in security and operational efficiency, the protocol allows miners to take a more active role in determining the contents of the blocks they mine.
The successful mining of the block demonstrates that miner controlled block construction can function in a live production environment, potentially encouraging wider adoption of Stratum V2 across the Bitcoin mining industry.
GoBTC Pay Transactions Included in the Block
The block also included transactions associated with GoBTC Pay, an open source protocol developed by GoMining for instant Bitcoin payments.
By including GoBTC Pay transactions in its self constructed block template, GoMining demonstrated one of the practical applications of miner controlled block creation. The achievement shows how mining companies can support their own Bitcoin-based services without depending entirely on mining pool operators to determine which transactions are included.
According to the company, GoBTC Pay is a non custodial instant Bitcoin payments protocol that was introduced during Consensus Miami in May 2026.
Company Leaders Highlight the Milestone
Commenting on the achievement, Mark Zalan, CEO at GoMining, said:
Alejandro De La Torre, CEO and Co-founder at DMND, also highlighted the significance of the development, stating:
Why This Matters for Bitcoin Mining?
For years, mining pools have played a central role in deciding which transactions are included in Bitcoin blocks. While pooled mining has helped miners earn more consistent rewards, it has also concentrated block construction decisions in the hands of pool operators.
The successful deployment of Stratum V2 in a production mining environment suggests that miners can now regain greater influence over block creation without sacrificing the advantages of pooled mining. If adopted more broadly, the protocol could contribute to a more decentralized and flexible Bitcoin mining ecosystem.
GoMining currently serves more than 5 million users and ranks among the top ten Bitcoin miners globally by hashrate, operating data centers in the United States and other international locations. The company continues to expand its Bitcoin ecosystem through tokenized hashrate services, payment products, and mining infrastructure.
CoinLaw’s Takeaway
In my experience, improvements to Bitcoin mining infrastructure often happen quietly before they become widely recognized. I found this development noteworthy because it moves Stratum V2 beyond theory and into real world production. If more miners begin creating their own block templates while remaining in mining pools, it could strengthen decentralization and give miners greater influence over the Bitcoin network without changing the economic benefits of pooled mining.
