@midnight-ntwrk/onchain-runtime v0.2.2 / ContractMaintenanceAuthority

Class: ContractMaintenanceAuthority

A committee permitted to make changes to this contract. If a threshold of the public keys in this committee sign off, they can change the rules of this contract, or recompile it for a new version.

If the threshold is greater than the number of committee members, it is impossible for them to sign anything.
