/*
Proxy contract is a contract deployed in NeoFS side chain.

Proxy contract pays for all multi signature transaction executions when notary
service enabled in side chain. Notary service prepares multi signed transaction,
however they should contain side chain GAS to be executed. It is inconvenient to
ask Alphabet nodes to pay for these transactions: nodes can change over time,
some nodes will spend side chain GAS faster, it creates economic instability.

Proxy contract exists to solve this issue. While Alphabet contracts hold all
side chain NEO, proxy contract holds most of the side chain GAS. Alphabet
contracts emits half of the available GAS to the proxy contract. Address of the
Proxy contract is used as the first signer in the multi signature transaction.
Therefore NeoVM executes Verify method of the contract and if invocation is
verified, then Proxy contract pays for the execution.

Contract notifications

Proxy contract does not produce notifications to process.
