Blockchain implementing reliability database

This invention describes a system that uses a blockchain to keep track of how reliable or trustworthy external data sources are. When a user needs to know if an outside data source can be trusted, the system gathers information from various places, combines it to create a reliability score, and then provides that score. The claims narrow this to a specific computer system that regularly updates these reliability scores and stores them on a blockchain ledger, requiring agreement from other network participants before changes are finalized.
