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.
