A method for storing a cryptocurrency private key offline, including: encrypting the cryptocurrency private key using a primary encryption key; sharding the encrypted cryptocurrency private key into a plurality of alpha shards; generating beta shards by encrypting the alpha shards with secondary encryption keys; and storing representations of the beta shards offline. The method can additionally or alternatively include: retrieving the representations of the beta shards from the offline storage; decrypting the beta shards into the alpha shards based on the secondary encryption keys; reconstructing the encrypted cryptocurrency private key by recombining the alpha shards; and decrypting the encrypted cryptocurrency private key with the primary encryption key.
