Disclosed are examples of systems, apparatus, devices, computer program products, and methods implementing aspects of a decentralized system for security and access control associated with digital content. In some implementations, a software stack is executed to provide fabric nodes of an overlay network. A transaction encrypted with a private key of a client can be recorded in a ledger identifying addresses of fabric nodes of the overlay network. The transaction can be identified by a transaction identifier (ID), and the private key can be part of a public/private key pair representing an account of the client on the ledger. A digital contract can be invoked, where the digital contract represents one or more terms of access for digital content stored in the overlay network. Controlled client access to the digital content can be based on an authorization token obtained from the client.
