Blockchain and world state. The result of the transaction will be reflected in the world state. The example in the figure shows the blockchain and the change of the world state. The transaction recorded in the blockchain is the transaction of the user’s registration, the user’s getting access permission, and the user’s revocation. The world state first records the user’s identity and public key , then records the user’s permission value , and finally sets the permission value to 0.
