On Byzantine Fault Tolerance in Blockchain Systems

It’s not easy to achieve consensus in distributed systems. This problem is generally called “The Byzantine General’s’ problem.” Byzantine failures are common failures in software design, process, quality, and applications in software. Blockchain applications, starting with Bitcoin’s Proof-of-Work consensus method, are today proposing solutions to this challenge.The Byzantine Fault Tolerance (BFT) is a proposed alternative consensus algorithm to the better know
