   Not entirely sure if TestBlockValidity tests all types of block validity, but it looks like it nearly does, making this kinda easy? If it does, its generally quite useful to have a way to as Bitcoin Core if a block would be valid, ignoring its PoW, so having that be public would be nice.

   At a glance, this looks like what you’re looking for? i.e. getblocktemplate’s proposal mode: https://github.com/bitcoin/bips/blob/master/bip-0023.mediawiki#block-proposal

   Ah, thanks. I always forget about getblocktemplate’s options (and the BIP isn’t always useful as IIRC only part of it was ever implemented).

    It’d be nice to have this in the mining protocol.

    #31564 adds this to the Mining interface. It’s not needed for the Stratum v2 Template Provider, so lower priority for me. But the Job Declarator Server could use it, once SRI has bindings for IPC.

    Additionally it introduces a checkblock RPC, which seems easier to use and easier to expand later.

    Finally it can verify weak block proof-of-work.
