`aux_hash`|A 32-byte hex-encoded hash of the `aux_blob` - the same value that was returned by `merge_mining_get_job`.
`blob`|Monero block template that has enough PoW to satisfy difficulty returned by `merge_mining_get_job`. It also must have a merge mining tag in tx_extra of the coinbase transaction.
`merkle_proof`|A proof that `aux_hash` was included when calculating Merkle root hash from the merge mining tag
`path`|A path bitmap (32-bit unsigned integer) that complements `merkle_proof`
Note that `merkle_proof` only contains a vector of 32-byte hashes for `aux_hash` to be combined with. It can be verified by running this pseudo-code and functions from `merkle.cpp` (adapt it to your codebase):
