A method and device for issuing an identity certificate to a blockchain node in a blockchain network includes issuing a first identity certificate to a first terminal. a second identity certificate issuance request that is from the first terminal and that is made by using the first identity certificate is received and a second identity certificate is issued to the first terminal, which forwards the second identity certificate to a second terminal. A third identity certificate issuance request that is from the second terminal and that is made by using the second identity certificate is received and a third identity certificate is issued to the second terminal, which forwards the third identity certificate to a third terminal.

Method for issuing identity certificate to blockchain node and related apparatus

An identity certificate may be issued to a blockchain node. The issuance may include issuing a first identity certificate to a first terminal and receiving a second identity certificate issuance request that is from the first terminal. A second identity certificate may be issued to the first terminal, and a third identity certificate issuance request is received from the second terminal. A third identity certificate is issued to the second terminal, so that the second terminal forwards the third identity certificate to the third terminal.

A blockchain network includes a service sub-network, a consensus sub-network, and a routing layer configured to isolate the service sub-network from the consensus sub-network. A data processing method in the blockchain network includes: receiving a data processing request transmitted by a service node in the service sub-network; performing identity verification on the service node according to the data processing request; obtaining a running load of each consensus node in the consensus sub-network when the verification succeeds; determining, from the consensus sub-network according to the running load, a target consensus node configured to process the data processing request; and forwarding the data processing request to the target consensus node, and performing corresponding data processing on the data processing request by using the target consensus node.

Data processing method and apparatus in blockchain network, storage medium, and computer device

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.
