Abstract: Systems and methods are described for policy-validated transactions using a centralized or distributed ledger. A request to execute a transaction and a transaction signature is received from a user's computing device. The transaction signature is generated with a private key of the user's computing device. The transaction corresponds to a token associated with the user's computing device and the transaction is subject to a first policy of a set of one or more policies. The transaction signature corresponds to the request to execute the transaction is determined using a public key of the user's computing device. In response to the determination, the token associated with the user's computing device is retrieved from the centralized or distributed ledger. The transaction is executed if the token is associated with the first policy and the token is valid.
