TTJ is to create a decentralized low-cost and efficient distributed storage application public chain. Any hardware device with storage space and network access functions can be connected to TTJ. TTJ is a new incentive layer built on IPFS, which allows more people to participate in IPFS by rewarding miners for sharing storage resources and retrieving and distributing resources. In addition, TTJ also adopts the innovative mechanism of DPOS+POC, which perfectly avoids the direct contradiction between equipment efficiency and resource allocation, distributes super nodes all over the world, realizes decentralization in the true sense, and then utilizes the storage and mining of the POC mechanism, Reorganize and reuse social idle resources, use distributed data storage to form a huge data distribution network, solve traditional data problems, and jointly promote the application of IPFS with Filecoin.
