Timer proposes a distributed, secure and scalable content incentive protocol. The Timer protocol can provide an economics-based incentive model and a cryptography-based trust environment for the video and streaming media content community. Timer has built a blockchain with high scalability, strong robustness and low latency from the protocol layer, which can well meet the needs of upper-layer video and streaming media applications. In addition to on-chain transactions and smart contracts, the Timer protocol also records important information such as intellectual property (IP) into a blockchain containing Tendermint and proof of contribution, forming an open, transparent and tamper-proof transaction record.
