Abstract
Methods, systems, and apparatus, including medium-encoded computer program products, for secure storage and retrieval of information, such as private keys, useable to control access to a blockchain, include, in at least one aspect, a method including: receiving a request to take an action with respect to a vault of multiple different vaults in a cryptoasset custodial system; authenticating, by an HSM, the policy map for the vault based on a cryptographic key controlled by the HSM; checking, by the HSM, the action against the policy map for the vault when the policy map for the vault is authenticated based on the cryptographic key controlled by the HSM; and effecting, by the HSM, the action when the action is confirmed to be in accordance with the policy map for the vault.
