Description：BitTorrent is a popular P2P file sharing protocol where users can freely share data and large files such as movies, shows and audio files over the Internet. Launched in 2001, BitTorrent has long been a pioneer in decentralized technology due to its peer-to-peer architecture. Tron founder Justin Sun acquired Torrent in 2018. In February 2019, BitTorrent released the local token BTT to help expand its protocol and inspire network participants. In December 2021, BitTorrent announced the launch of BitTorrent Chain, a heterogeneous cross-chain interoperability protocol that adopts the PoS mechanism and utilizes sidechains to extend smart contracts.
