DATUM

The DATUM Gateway moves block template construction from the mining pool onto your own node. Normally a pool decides which transactions go into the block your hardware is working on. With DATUM your Bitcoin node builds that template and your miners work on it — as the project puts it, the real miner is whoever runs the node, and here that is you.

It acts as a bridge between three things: your Bitcoin node, which supplies templates over RPC using getblocktemplate; your mining hardware, which connects over Stratum v1 with version rolling, also known as ASICBoost; and optionally a DATUM-supporting pool. Solved blocks can be submitted straight to the network for true solo mining.

Mining for pooled rewards is still possible without surrendering template control. The pool coordinates how the reward is split according to the work you contributed, but it does not construct your work. Communication runs over the encrypted DATUM protocol, and pools such as OCEAN pay miners directly from the generated coinbase through their TIDES system.

Why this matters beyond your own setup: deciding which transactions get mined is real influence over Bitcoin, and today it sits with a handful of pools. Building templates locally hands that decision back to individual miners. Bitcoin Knots is recommended over Bitcoin Core here for the finer control it offers over how templates are assembled.

It needs a fully synced node, a 64-bit Linux system, and mining hardware that can reach your MyNode. Bitcoin only, by design.
