Blockchain implementing reliability database

This invention describes a system that uses blockchain technology to keep track of how reliable external data sources are. When a change is proposed to an off-chain data source's reliability score, the system checks if enough network participants agree on the new score. If they do, the updated reliability score is recorded, and a reference to this change is permanently stored on the blockchain. The claims specifically focus on a computing system within a blockchain network that stores this reliability data as part of its ledger.
