As the first scalable heterogeneous cross-chain interoperability protocol in the industry, BitTorrent Chain boasts competitive edges across the board. First, with the deployment of multi-node verification, BitTorrent Chain is fully decentralized, achieving off-chain aggregation and smart contract extension through side chains. In addition, BitTorrent Chain promises faster transaction speed and a better user experience. Plus, its secure main chain, coupled with multi-node verification, safeguards the security of each transaction. Last but not least, it also frees users from the persistent high handing fees as its transaction fees are surprisingly low.
