Livepeer is a decentralized infrastructure protocol that allows users to upload, transcode, and serve video content & run AI pipelines. It operates on a network with different node types including Gateways (formerly Broadcasters), Orchestrators, and Transcoders. The protocol uses smart contracts deployed on Ethereum Mainnet and Arbitrum Mainnet, with the native token LPT (Livepeer Token). Since the Confluence upgrade, the protocol primarily runs on Arbitrum Mainnet.
