Abstract: A blockchain network may be used to improve upon public-key infrastructure by providing for fast and secure registration, revocation and update of digital certificates. A public key may be recorded on the blockchain by a certificate authority in such a manner that any third party may quickly and easily verify that the public key is certified by the certificate authority and that the certification has not been revoked. The certificate authority may be able to revoke the certification nearly instantaneously, and/or may be able to simultaneously certify a new key for the same entity while revoking the old key. In some cases, the ability to revoke a certification may be given to the owner of the public key or, in some cases, to one or even a group of other entities.
