Abstract
A license for software distributed to multiple users can be validated using a peer-to-peer network, asymmetrical cryptography and an essentially hack-proof public data store of licensing information, avoiding the need for a licensing server or central coordination by servers or host computers. Instances of the licensed software are implemented on the nodes of the peer-to-peer network. A distributed, immutable data store where each segment of data of the series of segments in the data store include a hash of the previous segment. Licensing transactions can be recorded and validated using the distributed, immutable data store. Licensing transactions can include but are not limited to provisioning, de-provisioning, activation and deactivation transactions. The license processing logic can be integrated into the licensed application software, so that once the licensed software is implemented on a user's computer, license generation, license revocation, license validation and license invalidation proceed automatically without the need for any intervention.
