Hot committee credential script

NFT asset class parameter

The hot committee credential script requires a specific NFT asset class to function. This asset class gets inlined as a parameter into the code of the script directly when it is compiled and initialized.

Rules

The hot committee credential script enforces two rules:

The purpose of the script execution must be Voting.
The transaction must consume a UTXO which contains the the given NFT.

Warning

Note that the hot committee credential script does not check:

Details of the vote, including the identity of the voter. This check is unnecessary, as the ledger rules would not ask a hot committee credential to authorize votes by other voters.
That the NFT is actually an NFT, as it doesn’t have access to sufficient information to determine this. For that matter, it doesn’t check that only one token is spent — in fact, the minting asset class could be the ada asset class. Although the tools we provide to build the credential would not allow this, the script itself doesn’t forbid it. It is the responsibility of the credential creator to choose an appropriate NFT.

Datum

Committee script credentials do not have a datum.

Redeemer

Untyped, not used. The most efficient is to use the integer 0 for the redeemer.
