TTJ is a decentralized, low-cost, and efficient distributed storage application public chain that can be accessed by any hardware device with storage space and network access functions. TTJ is a new incentive layer built on IPFS to reward miners for sharing storage resources and retrieving distribution resources, allowing more people to participate in IPFS. In addition, TTJ also adopts an innovative mechanism of DPOS+POC, perfectly avoiding the direct contradiction between device efficiency and resource allocation. It distributes super nodes around the world, achieving true decentralization, and then utilizes the storage and mining of POC mechanism to reorganize and reuse idle resources in society, forming a huge data distribution network through distributed data storage, solving traditional data problems, and working together with Filecoin to promote the implementation of IPFS applications....
