  • Systems and methods for re-using cold storage keys
    Patent number: 11943350
    Abstract: In certain embodiments, the use of re-usable cold storage keys to sign messages may be facilitated. In some embodiments, an offline computer system (operating within an offline computing environment) may obtain, from a removable computer-readable storage medium, signing key shards corresponding to a signing private key and a blockchain transaction to be signed, where the signing key shards satisfy a key shard threshold that is (i) a number of key shards required for reconstructing the signing private key and (ii) less than a number of key shards derived from the signing private key using a ceremony key. The offline computer system may form a ciphertext of the signing private key using the signing key shards and reconstruct the signing private key by decrypting the ciphertext using the ceremony key. The offline computer system may sign the blockchain transaction using the signing private key.
