// NeoFSID contract description.
|
||||
/*
|
||||
NeoFSID contract is a contract deployed in NeoFS side chain.
|
||||
|
||||
NeoFSID contract used to store connection between OwnerID and it's public keys.
|
||||
OwnerID is a 25-byte N3 wallet address that can be produced from public key.
|
||||
It is one-way conversion. In simple cases NeoFS verifies ownership by checking
|
||||
signature and relation between public key and OwnerID.
|
||||
|
||||
In more complex cases, user can use public keys unrelated to OwnerID to maintain
|
||||
secure access to the data. NeoFSID contract stores relation between OwnerID and
|
||||
arbitrary public keys. Data owner can bind or unbind public key with it's account
|
||||
by invoking Bind or Unbind methods of NeoFS contract in main chain. After that,
|
||||
Alphabet nodes produce multi signed AddKey and RemoveKey invocations of NeoFSID
|
||||
contract.
|
||||
|
||||
Contract notifications
|
||||
|
||||
NeoFSID contract does not produce notifications to process.
