Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a cryptoasset custodial system using power down of server computers to protect cryptographic keys. The cryptoasset custodial system includes a plurality of server computers. Each server computer of the plurality of server computers includes a volatile memory configured to store a cryptographic key associated with a cryptographic transaction to be performed, by the server computer, on a blockchain. A computing device is communicatively coupled to the volatile memory and configured to perform, using the cryptographic key, the cryptographic transaction on the blockchain. Responsive to detecting an interruption in an electrical power supply to the server computer, the stored cryptographic key is deleted from the volatile memory to prevent access to the cryptographic key.
