LBRY uses a database, that everyone has access to, to store metadata related to digital content and provide pointers to a more traditional decentralized P2P network like BitTorrent. The blockchain also provides publisher identities, human-friendly URLs (e.g. lbry://@MinutePhysics/magnetic-levitation), and a payment mechanism.
This decentralized db allows anyone to access the data without relying on one source.
