/*
FrostFS contract is a contract deployed in FrostFS mainchain.

FrostFS contract is an entry point to FrostFS users. This contract stores all FrostFS
related GAS, registers new Inner Ring candidates and produces notifications
to control the sidechain.

While mainchain committee controls the list of Alphabet nodes in native
RoleManagement contract, FrostFS can't change more than 1\3 keys at a time.
FrostFS contract contains the actual list of Alphabet nodes in the sidechain.

Network configuration is also stored in FrostFS contract. All changes in
configuration are mirrored in the sidechain with notifications.
