Abstract: Embodiments of this application disclose a permission verification method, and related apparatuses. In the embodiments of this application, a permission operation request is received by a first node device in a blockchain from a client, and the permission operation request is forwarded to a second node device in the blockchain; a first contract execution result is obtained according to the permission operation request; a second contract execution result broadcasted by the second node device is received based on the permission operation request; and the user permission verification is determined to succeed in a case that the first contract execution result is consistent with the second contract execution result. This solution implements decentralized permission verification based on a blockchain permission management contract system, thereby improving the data security.

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: A method for replacing an identity certificate in a blockchain network includes a service subnet, a consensus subnet, and a routing layer used for isolating the service subnet from the consensus subnet. The method includes: receiving a root certificate replacement notification transmitted by a certificate authentication center; obtaining a public key corresponding to the certificate authentication center; verifying the root certificate replacement notification by using the obtained public key; forwarding the root certificate replacement notification to a consensus node in the consensus subnet after the validation succeeds, so that the consensus node records the root certificate replacement notification into a latest data block after a consensus on the root certificate replacement notification is reached; and requesting, when the data block is received, the certificate authentication center to replace an identity certificate. A new identity certificate obtained through requesting is authenticated with a new root certificate of the certificate authentication center.

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.

Abstract: A computing device receives network message data. The computing device determines a message processing type corresponding to the network message data. In accordance with a determination that the message processing type is a consensus processing type, the computing device obtains a consensus parameter corresponding to the network message data. In accordance with a determination that the consensus parameter does not meet a consensus validity condition, the computing device classifies the network processing message data as an invalid consensus message; and filters out the network message data.
