Proof of Work Existing Blockchain technology is working on the core concept of 'Proof Of Work' (POW). A proof-of-work (PoW) is a protocol that is difficult to compute but easy to verify. It can be verified in far less time than it took to compute in first place. The process involves scanning for a value that when hashed, (such as with SHA-256), the hash begins with a number of zero bits. The average work required...
