Cardano is a proof-of-stake blockchain platform powered by its native cryptocurrency, ADA. Launched in September 2017 by IOHK, Cardano distinguishes itself through a scientifically rigorous development process and a unique two-layer architecture. This guide explores Cardano's fundamentals, advantages, and how it compares to other blockchain platforms like Ethereum and Bitcoin.
Introduction to Cardano
Cardano is a decentralized public blockchain often termed the "third-generation blockchain." Designed to support secure and scalable decentralized applications (dApps) and smart contracts, it uses the Ouroboros Proof-of-Stake (PoS) consensus mechanism. Unlike energy-intensive Proof-of-Work (PoW) systems like Bitcoin, Cardano's PoS model enhances energy efficiency and network security by incentivizing validators to act in the network's best interest.
Key Features:
- Ouroboros PoS: Reduces energy consumption and minimizes centralization risks.
- Academic-Led Development: Peer-reviewed research ensures protocol robustness.
- ADA Cryptocurrency: Facilitates transactions and staking rewards.
Cardano’s Two-Layer Architecture
Cardano’s ecosystem comprises two distinct layers, enabling flexibility and scalability:
1. Cardano Settlement Layer (CSL)
- Function: Manages ADA transfers between users.
- Scripting Languages: Plutus and Marlowe streamline value movement and overlay network support.
2. Cardano Computation Layer (CCL)
- Function: Executes smart contracts and dApps.
- Innovation: Mimics Bitcoin’s Rootstock (RSK) for protocol scalability and hardware security integration.
This separation allows independent upgrades, fostering faster innovation and eliminating irrelevant metadata.
Innovations and Advantages of Cardano
