Hi @honglouzzc, the error means that the identity key file, located in data-dir/identities (probably in /mnt/data/spacemesh/identities/identity.key) doesn't match the public key (in /mnt/data/spacemesh/post_data). Did you change go-spacemesh versions 1.4 -> 1.3 -> 1.4?

Thank you very much. It is caused by the inconsistency of node id. The key location was redefined in version 1.4.0.
