DMND, the Stratum V2 mining pool, announced on August 14 an integration with Mempool Accelerator that introduces new transaction acceleration functionality for Stratum V2 miners. The integration places individual miners in control of transaction acceleration and prioritization.

The arrangement represents a fundamental shakeup of the legacy transaction accelerator model. Accelerators exist to help users whose transactions become stuck when network demand pushes fees above what their original transaction paid; paying an additional out-of-band fee gets that transaction prioritized for inclusion in an upcoming block. Such products have historically been offered by mining pools rather than by the miners themselves, which has left the pools in the position of both deciding which transactions to prioritize in their block templates and pocketing the additional revenue generated by accelerating them.

On DMND, individual miners now handle the prioritization selection themselves using Stratum V2, the upgrade to the Stratum mining protocol whose Job Declaration capability allows miners to construct their own block templates rather than depending on the pool to do so. When a block template containing accelerated transactions is mined, the individual miner who found that block collects the additional revenue for the acceleration, income that arrives on top of the block subsidy and standard transaction fees that make up ordinary mining revenue.

"Our premise is simple: when miners build their own blocks through DMND's Stratum V2 implementation, they unlock revenue streams that were never available to them before," said Alejandro De La Torre, CEO of DMND. "Accelerated transactions are one of those streams. The pool used to prioritise them and the pool used to collect for them. On DMND the miner does both. It is a paradigm shift in how miners earn."

The integration is described as a first-of-its-kind implementation of a transaction accelerator system, opening the door to new revenue streams for individual miners. Now that direct revenue sharing of this additional income has been demonstrated, it raises the question of why other mining pools that own or integrate with accelerator services are not pursuing similar revenue-sharing arrangements. This design and revenue sharing were made directly possible by Stratum V2.

"Mempool Accelerator lets anyone get their stuck transaction confirmed by paying an out of band fee, which prioritizes their transaction with over 80% of the network hashrate. DMND's integration is the first of its kind, Stratum V2 miners using Job Declaration can now earn their share of that revenue," said Orange Surf, Head of Strategy & Research at mempool.space.
