Cardano (ADA) is often referred to as the "third-generation blockchain". The first generation, Bitcoin, operates on a proof-of-work model and is primarily used as a store of value. The second generation, Ethereum, introduced smart contracts but faced scalability limitations. Building upon these two, Cardano improves the blockchain architecture and consensus mechanisms to address issues such as scalability, interoperability, and sustainability.
Cardano's unique two-layer architecture separates the ledger of account values from the operations behind them. This structure enhances smart contract flexibility and scalability. The Cardano Settlement Layer (CSL) is used for transferring ADA, Cardano's native cryptocurrency, while the Cardano Computation Layer (CCL) handles smart contract execution, ensuring more efficient transactions.
Cardano also introduced Ouroboros, the first provably secure proof-of-stake (PoS) algorithm. It’s the first blockchain protocol to be based on peer-reviewed academic research, a defining feature that sets Cardano apart from other blockchains.
