The technical framework and technical requirements of blockchain access control, including the subject, object, and access control policy of each layer of the blockchain is specified in this standard.

The standard establishes access control requirements for blockchain systems. The standard addresses the following access control attributes of the system, including but not limited to: a) Node permissions--The permissions of block generation, block synchronization, block verification and broadcasting, and sending transactions. b) Smart contract access permissions--Interface access control, user access control, and hybrid access control. c) User permissions--Registered user permissions and unregistered permissions. The concept of role is applied to differentiate the permissions of registered users, which means permissions vary according to the role of a user. d) Global permissions--User access to deploy smart contracts, and to read smart contracts.
