Blockchain Consensus Mechanisms Compared Across Bitcoin, Ethereum, XRP Ledger and CometBFT

A comparative study of blockchain consensus mechanisms—including Bitcoin, Ethereum, Ripple, and Tendermint—evaluates peer-to-peer networks, native cryptocurrencies, transaction validation, block creation, consensus protocol design, and application development. Bitcoin relies on proof of work. Miners hash block headers until the result falls below a difficulty target, and full nodes select the chain with the most cumulative work. ...
