Blockchain Data Availability Scheme with Strong Data Privacy Protection

Blockchain, with its characteristics of non-tamperability and decentralization, has had a profound impact on various fields society set off boom in the research application blockchain technology. However, technology faces problem data availability attacks during application, which greatly limits scope domain applications. One most advantageous researches to address this is scalable solution that integrates coding theory design into Merkle tree promise. Based scheme, paper combines zero-knowledge accumulator higher efficiency security local repair coding, proposes scheme strong dataset privacy protection. The first encodes block information ensure tamper-proof data, then uses store encoded information. Its main purpose use property protect accumulation stored from being leaked no other about revealed transmission. It fundamentally reduces possibility attackers generating fraudulent by imitating further resists attacks.
