A method and apparatus is presented for announcing the existence of cryptographic key pairs within a distributed ledger system in which no central trusted authority is available, consisting of sending a key announcement message by a network connected device to other network connected devices over a peer-to-peer network for inclusion in the distributed ledger. Once a valid key announcement message for a public key is included in the ledger, any future transactions that reference an address associated with the public key or other messages concerning said public key are accepted by other network connected devices on the peer-to-peer network and are included in the distributed ledger. If transactions or other messages reference an address not associated with an announced public key, they may be rejected by the peer-to-peer network and may not be included in the distributed ledger.
