Provided is a blockchain management apparatus comprising at least one hardware processor configured to implement a block generation order control unit which prevents a block generation node of a plurality of blockchain nodes from generating a new block of a blockchain in response to a determining, by the blockchain management apparatus, that the new block is a block generated by the block generation node within a unit section, wherein the unit section corresponds to a preset number of blocks measured from a current block corresponding to a current block height of the blockchain, and the blockchain management apparatus manages a permission-based blockchain network including the plurality of blockchain nodes.

System for processing data based on blockchain and operating method thereof

A digital identity management method based on a blockchain-based technology is provided. In some exemplary embodiments, the method comprises: performing a first process for storing identity identification information of a subscription request in a first block of a blockchain in response to the subscription request from a service request device and then obtaining a block hash value of the first block as a result of performing the first process, performing a second process for storing the block hash value of the first block and data of authentication information of the subscription request in a second block of the blockchain and then obtaining a block hash value of the second block as a result of performing the second process, and inserting the block hash value of the second block into a digital identity data structure as a result of processing the subscription request.

Blockchain-based digital identity management method

A blockchain-based method is described which is related to transferring electronic currency from a payer to a payee. In some embodiments, a first process, a second process and a third process are performed. The first process includes receiving a processing request for a target transaction from a terminal of a payer, and transferring the processing request to a first blockchain node among a plurality of blockchain nodes. When a verification result indicates that the target transaction is valid, the method proceeds to performing the second and third processes. The second process includes transferring electronic currency from an electronic wallet of the payer to an electronic wallet of the payee. The third process includes recording data for the target transaction in a new block, and spreading the new block over the blockchain network. In some embodiments, the second process and the third process are performed in parallel.
