An Effective Big Data Sharing Prototype Based on Ethereum Blockchain

Because of its many advantages, big data has been extending to various domains science, health, education, and commerce. Despite applications, sharing typically suffers from some key issues, such as user control, lack incentives, cost, the right data. This paper proposes a decentralized prototype improve applications services The method makes use Ethereum blockchain related technologies systematically recommend implementation guidelines. research provides detailed description design each sublayer system. As is based on technology, technical points are properly addressed in layers. For evaluation, relevant were collected, functional testing was performed. A comparison performed about frequency consensus performance similar platforms. dual mining node proposed succeeded processing 1366 blocks 300 messages. comparatively satisfactory file access time range 10 m 20 s transmission between 100 200 achieved. results obtained show that this can effectively verify feasibility model, layered architecture, mechanism. testing, practical projects implemented evaluated. promising testify offers theoretical background for innovative domain specialized guidelines implementation.
