Computer-readable media, systems and methods may improve security, authorization, and auditability of documents. For example, computer systems for serving documents may be improved to provide secure access and control through challenges that are validated with self-executing on-chain document license contracts that enforce entitlements that specify users and their authorized document actions. Such entitlements may be generated by the user who created the document. As such, a user may retain over authorizations and document actions that are permissible with respect to the document even after the user has transferred a copy of the document. Furthermore, the computer systems may be improved to write an on-chain audit log of document actions, providing an immutable record of the document actions.
