Abstract: A method for electing a representative node device for a blockchain system includes: receiving IP address information of a first node device, the first node device being in a candidate state for a representative node device; receiving, from the first node device, an IP address obtaining request for requesting IP address information of a representative node device; when the first node device is determined to be a representative node device of the blockchain system elected in a current election process, transmitting, to the first node device, an IP address list comprising IP address information of representative node devices elected in the current election process; and when the first node device is determined not to be a representative node device of the blockchain system elected in the current election process, skipping the IP address obtaining request.

Abstract: Aspects of the disclosure are directed to a method for use on a blockchain network that includes an accounting node subnetwork having accounting nodes configured to record a data block onto a blockchain and a service node having service nodes configured to verify data blocks recorded by the accounting nodes onto the blockchain. The method can include generating a signature based on transaction information to be included in a data block to be added onto the blockchain by using a key specific to the accounting node. The method can further include adding the transaction information and the generated signature to the data block and adding the data block onto the blockchain, and transmitting the signature to the service nodes in the service node subnetwork, so that the service nodes perform signature verification on the signature based on the key specific to the accounting node.

Abstract: This application provide a data management method for a blockchain system, a medium, and an electronic device. The system includes an accounting node sub-network and a service node sub-network. The method includes: adding, after an accounting node generates a first data block, first key information used for verifying a block header of a second data block generated after the first data block to a block header of the first data block; generating a signature corresponding to the first data block, and adding the signature corresponding to the first data block to the block header of the first data block; and releasing the block header of the first data block to the service node sub-network, to cause a service node to verify the signature included in the block header of the first data block, and obtaining the first key information after a successful verification to verify the block header of the second data block.

Abstract: This application discloses a key generation method and apparatus, a device, and a medium. The method includes transmitting a key negotiation request to a consensus node in a blockchain network, to request a key verification parameter; negotiating a collaboration key pair with a second device to obtain a first private key component and a shared public key in the collaboration key pair; signing the key verification parameter by using the first private key component, to obtain a first signature component; generating transaction data according to the first signature component and the key verification parameter; transmitting the transaction data to the second device. The consensus node performs a consensus on the negotiation result data, and after the negotiation result data passes the consensus, submits the negotiation result data to a blockchain of the blockchain network.

Abstract: Data routing with a forwarding process of service data can avoid problems of offline nodes. The forwarding process for data routing can also improve the fault tolerance and service data can be quickly transmitted to a corresponding data pool. Using consensus nodes and a target data pool with routing and forwarding tables along with subtrees from a trie tree can improve the routing. Subtrees may be obtained by splitting the trie tree from a root node by using a first leaf node as a benchmark, which correspondingly represents a data pool of the consensus node. The routing and forwarding table is configured to record addresses of data pools correspondingly represented by a preset quantity of leaf nodes in a corresponding subtree.
