DMND and Rootstock Labs have launched a new feature that combines Stratum V2 protocol with merge-mining capabilities, allowing Bitcoin miners to control block template construction while simultaneously mining on the Rootstock sidechain. The integration aims to advance decentralization in Bitcoin mining operations by giving individual miners more control over the merge-mining process.
How the Integration Works
The new implementation enables miners using DMND's pool to construct their own block templates through Stratum V2 while also selecting and including merge-mined block commitments from the Rootstock (RSK) sidechain. Miners can now claim sidechain rewards in rBTC directly without intermediary custody or revenue sharing arrangements with the pool.
Merge-mining allows multiple blockchains to share proof-of-work from the same mining infrastructure. The child chain (Rootstock) structures its block headers to include commitments within the parent chain's (Bitcoin) blocks, typically in the coinbase transaction. This enables miners to mine both chains simultaneously—when they find a valid block for Bitcoin, they also produce one for Rootstock.
Implications for Mining Operations
The partnership represents a significant technical development for mining professionals, particularly those operating in pool environments. By decentralizing block template construction and reward distribution, the integration could influence how mining pools structure their operations and compensate participants.
Alejandro De La Torre, CEO and Co-Founder of DMND, emphasized the decentralization focus: "The miner controls the merge mining and the miner gets paid for the merge mining. More delegation of control to miners is our key support for further decentralisation of the Bitcoin ecosystem."
However, the long-term effects on mining decentralization remain to be seen. While the technology enables greater miner autonomy, real-world implementation will test whether these capabilities translate into measurably improved decentralization metrics.
For mining professionals and pool operators, this development signals continued evolution in mining infrastructure. Those working in mining operations, protocol development, or blockchain infrastructure roles should monitor how Stratum V2 adoption progresses and whether similar integrations emerge across other mining pools and sidechains.
