Consensus mechanisms are at the heart of how blockchains operate, and Ethereum and Cardano have taken two distinct routes to achieve the same goal, validating transactions and maintaining the integrity of their networks. Ethereum uses something called GHOST, which selects blocks based on how many child blocks they have, favoring the most "built-upon" chains. Meanwhile, Cardano uses a mechanism called Ouroboros, a proof-of-stake protocol where randomly chosen leaders create blocks in assigned time slots. Understanding these differences gives us a better appreciation of how blockchain ecosystems evolve and operate uniquely.. Want to learn more?
