- <Block header is on stack>
- OP_SHA256d
- PUSH...: various other merged chains as merkle links
- PUSH: N of merkle links
- OP_MERKLEROOT_FROMLINKS
Inside parent chain coinbase:
- PUSH: coinbase prefix midstate
- OP_SWAP
- OP_SHA256FINISH
- OP_SHA256 (to get a SHA256d result; the parent chain coinbase's txid)
- PUSH...: various other transactions in parent chain (as merkle links)
- PUSH: N of merkle links
- OP_MERKLEROOT_FROMLINKS (stack now has the parent chain tx merkleroot)
- PREPEND: parent chain version
- APPEND: parent chain header ending
- OP_SHA256d (stack now has the proof-of-work)
Dedicated merged mining:
- APPEND: 16-bit time offset
- APPEND: 48-bit nonce
- OP_SHA256d
