No one can guarantee the stability of enterprise signature, because enterprise signature is signed by enterprise certificate, so once the certificate is blocked, it will lead to the cancellation of enterprise signature.

There is a version of the ultra-stable enterprise signature. Through rare certificates and special technology, it can be guaranteed that the signature can be cancelled at most once a month, and the signature can be fully refunded after more than one time, which is also a guarantee for the stability of the signature.
