We described that Alice’s and Bob’s personal implementation — where by everyone knows and trusts Every person included — doesn’t have to have a blockchain (nor does it need to have miners to validate and append transactions to the cryptographically-secured blockchain).
“Reputation scores both equally for firms and men and women are right now siloed into distinctive platforms, and There's hardly any portability throughout platforms. Blockchain can enhance on this,” he states.
