TBC (Tunnel Boring Christian) is a main chain product that serves the mining ecosystem. Based on DAG technology, it provides a completely different distributed consensus method from current blockchain solutions. TBC ensures consistency while also taking into account decentralization, speed, provability, and resistance to DoS attacks. Can achieve large-scale low-cost consensus building, more efficient and fair Internet trust layer, and more scalable security consensus protocol.Shield tunneling chain always focuses on application scenario implementation thinking. Users can directly obtain computing power by using TBC in the ecosystem, and use it to pay mining electricity fees, custody fees, leasing, purchasing service fees, etc., thus redefining the value of the mining industry, and ultimately creating a blockchain computing financial service platform that integrates computing power services, financial services, circulation services, and information services....
