摘要： A permission control method, apparatus and system for a blockchain, and a node device. The method comprises: writing a preset correspondence between account roles and permissions into a block of a blockchain; determining a role of a target account configured to a user node to be added to the blockchain; and controlling, according to the correspondence and the role of the target account, a permission of the user node configured with the target account. In the method, by setting roles and permissions of blockchain accounts, user nodes configured with different accounts perform corresponding operations according to roles and permissions of the user nodes, so that only accounts having corresponding permissions can access a blockchain network, synchronize data on a blockchain and acquire data within a permission range; blockchain data is protected, and the security and privacy of the blockchain data are ensured.

摘要： The present disclosure discloses a method, apparatus, node, system for blockchain-based identity authentication. The method includes: receiving an authentication request sent by an authenticated party node, in the case that it is determined that the identity information of the authenticated party node and identity proof publishing node, and a digital signature of the identity proof publishing node on the identity information of the authenticated party node have been written into a blockchain, verifying the digital signature according to a public key of the identity proof publishing node; after the digital signature passes the verification, determining whether the authenticated party node has mastered a private key corresponding to the public key of the authenticated party node; and in the case that it is determined that the authenticated party node has mastered the private key, it is determined that the authenticated party node passes the identity authentication.

摘要： The present disclosure provides a method, apparatus, node, signature device and system for generating block of blockchain. The method for generating the blockchain block is applied to a first node in a blockchain network and includes: generating an original block according to a blockchain protocol; performing a digital signature operation on the original block to generate a signature block; and broadcasting the signature block in the blockchain network. By adoption of the method, a block generator of the block in the blockchain network may be confirmed via the digital signature thereof, and verifiable information is provided for the security of the blockchain network.

摘要： The present disclosure discloses a method, device and node apparatus for blockchain permission control. The method comprises: receiving target information sent by a node apparatus; acquiring an account address of a configured account of the node apparatus; acquiring, according to the account address, from a predetermined block stored with the account address and an account permission corresponding to the account address, the account permission corresponding to the account address; and processing the target information according to the account permission accordingly. In the present disclosure, node apparatuses are configured with corresponding accounts, and performing permission control on the accounts can restrict permissions of different node apparatuses so as to ensure security and privacy of blockchain data.
