1. A method of associating a blockchain address with a network identifier, the method comprising:
receiving, over a computer network and by a network identifier infrastructure operator, a request for a registration status of the network identifier;
retrieving, by the network identifier infrastructure operator and in response to the receiving the request, an association of the network identifier with the blockchain address;
signing, using a private key associated with the network identifier infrastructure operator and in response to the retrieving the association, a unique identifier to prevent replay attacks and the association of the network identifier with the blockchain address, wherein a signed association is determined based at least in part on the signing the association of the network identifier with the blockchain address; and
providing, in response to the signing and by the network identifier infrastructure operator, the signed association of the network identifier with the blockchain address over the computer network.
