Proof of Blockchain Work on The Security of Academic Certificates

The Proof of Work (PoW) consensus mechanism used in Bitcoin, along with other concepts, makes it increasingly popular. In this case, researchers introduce a new quantitative framework to analyze the security and performance implications of the various Consensus and network parameters of the Proof of Work Blockchain. Emerging innovative technology can be called Blockchain. Blockchain is a distributed digital ledger where transactions are recorded after verification. Transactions in the General ledger that have been verified by multiple clients in the Peer to Peer network using one of the many varied consensus algorithms to resolve problems within the network involving multiple nodes that cannot be used. The algorithm to be used is Proof of Work (PoW), a protocol that has a function to prevent cyber-attack activities (DDos) that can weaken a computer system resources. The idea behind the PoW algorithm is that certain jobs are done to block transactions before they are proposed to the entire network. For that, using the PoW consensus algorithm certificate on the Blockchain is certainly the creation of a real certificate and cannot be manipulated.
