Cardano

ADA

Research-driven blockchain built for sustainability and scalability.

Layer 1Created: 2017

๐Ÿ’กWhat is it?

Cardano is a proof-of-stake blockchain platform that emphasizes academic research and formal verification of its protocol.

๐ŸŽฏWhy was it created?

Cardano was created to provide a more secure and scalable infrastructure for DApps, with a research-first development approach.

โš™๏ธHow does it work?

Cardano uses the Ouroboros PoS protocol, which was the first peer-reviewed, formally verified blockchain consensus algorithm. Development is separated into multiple eras (Byron, Shelley, Goguen, Basho, Voltaire).

Technical Overview

Consensus Mechanism
Ouroboros Proof of Stake
Native Token
ADA
Supply Model
Maximum supply of 45 billion ADA. Staking rewards are distributed from a reserve over time.
Transaction Model
Extended UTXO (eUTXO) model โ€” extends Bitcoin's UTXO model with programmability.

๐ŸŒMajor Ecosystem Uses

  • โ€ขReal-world asset tokenization projects

โœ“ Strengths

  • โ€ขStrong academic and peer-reviewed foundation
  • โ€ขEnergy-efficient PoS consensus
