TTJ is designed to be a decentralized, low-cost, and efficient public chain for distributed storage applications. Any hardware device with storage capacity and network access can connect to TTJ. Built as a new incentive layer on IPFS, TTJ rewards miners for sharing storage resources and distributing content, encouraging broader participation in IPFS. Additionally, TTJ employs an innovative DPOS + POC mechanism, effectively avoiding the direct conflict between device efficiency and resource allocation. Super nodes are distributed globally, achieving true decentralization. The system utilizes storage mining through the POC mechanism, repurposing idle resources in society. Through data distributed storage, it forms a vast data distribution network, addressing traditional data issues and advancing the practical implementation of IPFS alongside Filecoin.
