but that also comes with the issue of trusting the miner whether they wouldn't take the puzzle reward themselves or not

Well, it is also possible to share some data, which is needed to mine a block (like transaction ID, transaction Segwit ID, etc.), without sharing transaction data. Then, it would be sufficient to mine a block, but the pool wouldn't know, if it is valid or not.

And also, if you want to prove, that you know the public key, but you don't want to reveal it, then you can share for example SHA-256 of that key, and then everyone can validate, that RIPEMD-160 of it is equal to the address, used in the puzzle.

For example:

This is the public key, which you want to keep secret: 04678afdb0fe5548271967f1a67130b7105cd6a828e03909a67962e0ea1f61deb649f6bc3f4cef3 8c4f35504e51ec112de5c384df7ba0b8d578a4c702b6bf11d5f
This is what you can share to prove, that you know the public key: 261c1eb21fc4708c6acbe1cfc6d4565652e9e768b620782898936b93000a6c02
This is the hash used in the address: 62e907b15cbf27d5425399ebf6f0fb50ebb88f18

Edit: And also, you can deposit funds on-chain, for example into "OP_RIPEMD160 62e907b15cbf27d5425399ebf6f0fb50ebb88f18 OP_EQUALVERIFY <yourScript>", and then, it would be possible to move those coins, only if you reveal the in-between step (which is 261c1eb21fc4708c6acbe1cfc6d4565652e9e768b620782898936b93000a6c02 in that example), and "<yourScript>" could contain any conditions, like some new public key, to avoid getting those funds captured by other mining pools.

application example:
this is the addr: 1GG6mV7acidZ461XvLJNcUxNicdpTFAL9Q
privkey: **
pubkey(to keep secret): 024693A3AED2774C420787C8DFCFB7B04A5CC456F49D724C20B919A9E42527EE78
i share this:
sha256: 07e96ec7a607ae6fef04c1a04786bdfdc1450c16388d4236e0890f100ae1c566
hash160: a764f0b1e02f57f995676949950e8d5bdc951966

your example not in blickchain, of course you know pubkey address by youself yourself

show pubkey from this address:
