Jan 18, 2021 · Blockchain Consensus is the safest way to validate transactions in Blockchain network. It's the basis for crypto industry. Everyone interested in crypto should know about Consensus. Check detailed guide. The most widely utilized and well-known consensus algorithm throughout the Blockchain ecosystem is the Proof of Work algorithm.

A consensus algorithm is a procedure through which all the peers of the Blockchain network reach a common agreement about the present state of the distributed ledger. In this way, consensus algorithms achieve reliability in the Blockchain network and establish trust between unknown peers in a distributed computing environment. The two variations of BFT consensus model that are prime in the Blockchain arena are PBFT and DBFT. Practical Byzantine Fault Tolerance (PBFT) PBFT is a lightweight algorithm that solves the Byzantine General’s problems by letting users confirm the messages that have been delivered to them by performing a computation to evaluate the decision about the message’s validity. In the past couple of years, we heard a lot about how blockchains are going to transform the business world and financial transactions. Few of the most crucial aspects of blockchain are speed… Blockchain is a new way of organizing data, it stores every change that has occurred and finally it arranges data in blocks.
