The past five years have seen a significant increase in the popularity of Decentralized Ledgers, commonly referred to as Blockchains. Many new protocols have been launched to cater to various applications serving individual consumers and enterprises. While research is conducted on individual consensus mechanisms and comparison against popular protocols, decisionmaking and selection between the protocols is still amorphous. This paper proposes a comprehensive comparative framework to evaluate various consensus algorithms. We hope that such a framework will help evaluate current as well as future consensus algorithms objectively for a given use case.
