📜 Policy ID

Compute the policy ID (script hash) of a native script, the kind of minting policy most tokens and NFTs use.

Native script: cardano-cli JSON or CBOR hex

Script types

sig requires a signature from the key with that hash. all, any and atLeast combine scripts. before allows minting only before the given slot, which is how NFT policies lock their supply; after only from that slot.

The policy ID is Blake2b-224 of a 00 tag byte followed by the script's CBOR. Changing anything, even the slot, gives a different policy.
