Generalized Ethereum Blockchain-based recommender system framework

作者：

Highlights：

• Blockchain technology is a decentralized data-sharing ledger across a large network of untrusted entities.

• e-business platforms share common data about users, items, and sellers.

• Proposed a generalized recommender system framework using Blockchain technology.

• Blockchain technology is adopted to share data between the e-business platforms.

• Proposed framework will help alleviate cold-start, sparsity, and shilling attack problems.
