A node, of a network of nodes with access to a distributed ledger, receives a request to verify the user has consented to a current version of terms (i.e., current terms) associated with a program. The node obtains, using the distributed ledger, historical consent data indicating a version of the terms to which the user has previously provided consent. The node performs a first verification procedure to determine the user has not consented to the current terms, provides an indication to a user device that the user has not consented to the current terms, and receives, from the user device, a message indicating an acceptance of the current terms. The node performs additional verification procedures to determine that the user is who consented to the current terms and updates the distributed ledger to include a record indicating that the user consented to the current terms.
