Cardano and Ethereum are both blockchain platforms supporting smart contracts, but they differ in approach and structure. Ethereum initially used a Proof-of-Work model, transitioning to Proof-of-Stake with Ethereum 2.0, while Cardano has used PoS from the start, making it more energy-efficient. Additionally, Cardano undergoes rigorous peer-reviewed research before implementing upgrades, ensuring a stable and secure platform. These differences often influence ADA’s market behavior, and those tracking ADA price can observe its comparative performance against Ethereum.
