What is Consensus ?
Consensus is a mechanism by which all nodes participating in a network agree upon proposed value by a node.
Most common types of Consensus algorithm in blockchain :
1.Proof of work – Bitcoin
2.Proof of stake – Ethereum
3. Proof of Authority – Ropsten/ Kovan network.
4. PBFT (Byzantie Fault tolerant systems) – Consensus is achieved by selecting node leaders by voting,round robin fashions etc.. (Corda ,Hyperledger).
Explanation of each of consensus algorithm above would be shared as a separate post.
