This whitepaper introduces the Theta Network, a decentralized video streaming and delivery network powered by a new blockchain and native token. The Theta Network aims to solve challenges in the video streaming industry by incentivizing users to share their bandwidth and computing resources as caching and relay nodes. This approach seeks to improve stream quality, reduce content delivery costs, and enhance viewer engagement through token rewards. The paper details the novel blockchain architecture, including its multi-level Byzantine Fault Tolerance consensus mechanism, aggregated signature gossip scheme, and resource-oriented micropayment pool designed for high throughput and scalability in video streaming.
