There is no script.

  Of course there's a script; every bitcoin tx output has a script. These challenges use the standard P2PKH script, i.e.: scriptPubKey: OP_DUP OP_HASH160 <pubKeyHash> OP_EQUALVERIFY OP_CHECKSIG scriptSig: <sig> <pubKey> https://en.bitcoin.it/wiki/Script https://en.bitcoin.it/wiki/Script

    Not every bitcoin tx output. With taproot (P2TR), scripts are optional, and outputs can be based solely on Schnorr signatures.

      P2TR outputs have a script that always starts with OP_1. That script may or may not commit to a tapscript.

    You know what I mean, there's no clever on-chain reward script.
