As you know, Blockchain is a distributed ledger so that all nodes have the same ledger for trust. It doesn't require a specific center authority and it reserve trust by using cryptographic. It uses Peer to Peer network and Proof-of-Work makes block added to blockchain after verify. The advantage of Blockchain is Distribution, Independency, and Transparency. I have used Blockchain technology in many projects and gained enough experience and knowledge as well. I am happy to describe my poor idea about your project, here.
