Cardano (ADAUSD) dis one of the projects altcoin investors swore by during the 2021 altseason. Cardano is similar to many flagship layer-1 smart contract blockchains like Ethereum (ETHUSD). This means that smart contracts can run on Cardano’s blockchain, and they’ll use ADA for gas fees. It is a proof-of-stake project.
It got the title of being the “Ethereum Killer,” supposedly destined to dethrone the Ethereum ecosystem as the leading alternative blockchain. Unfortunately, that never ended up materializing.
