A Research Survey on Applications of Consensus Protocols in Blockchain

A Research Survey on Applications of Consensus Protocols in Blockchain

The concept of blockchain, widely known as virtual currencies, saw a massive surge in popularity in recent times. As far as the security of the blockchain is concerned, consensus algorithms play a vital role in the blockchain. Research has been done separately, or comparisons between a few of them h...
