Decentralized mining on Bitcoin is an important area. We've developed a prototype within Stratum v2 that leverages STARK proofs to achieve a more trustless system and better preserve the strategies of individual miners.
Our demo shows the individual miner (JD client) generating a STARK proof for the validity of the coinbase transaction and the total fees of the block template, all without disclosing the list of transactions. The JD server can then verify this STARK proof, confirming the block template's validity and the claimed sum of fees, without gaining any knowledge about the specific transactions.
This also provides an advantage for mining pools from a regulatory perspective due to plausible deniability, which in turn improves the network's censorship resistance. While this is currently a proof of concept, our goal is to extend it to include full transaction validity in the future. We're keen to collaborate with teams working on decentralized mining and will also be exploring this with Datum.
