Cardano

ADA

Proof-of-Stake layer-1 blockchain built on peer-reviewed academic research and formal verification.

Blockchain Layer 12017

Résumé exécutif

Cardano is a proof-of-stake layer-1 blockchain founded in 2015 by Ethereum co-founder Charles Hoskinson and launched in 2017 by IOHK. Built with a peer-reviewed academic engineering approach, Cardano emphasizes formal verification, sustainability, and predictable smart contract execution.

Fonctionnement & Architecture

Ouroboros Proof-of-Stake Algorithm

Cardano utilizes Ouroboros, the first mathematically proven secure Proof-of-Stake consensus protocol.

Time is divided into epochs (5 days) and slots (20 seconds). Stake pools are elected as slot leaders to produce blocks, enabling liquid staking without slashing locks.

Extended UTXO (eUTXO) Architecture

Cardano adopts an Extended UTXO (eUTXO) model, extending Bitcoin’s UTXO model to support deterministic contrats intelligents.

This architecture prevents unexpected gas fee failures because transaction outputs and fees are computed locally prior to broadcasting.

Cas d'utilisation principaux

Peer-Reviewed Smart Contracts and Financial Infrastructure

Decentralized Digital Identity Systems (Atala PRISM)

Liquid Staking Governance and Treasury Funding (Voltaire)

Avantages clés & Considéraitons

Avantages

Rigorous peer-reviewed development approach reduces protocol flaws
Liquid non-custodial staking without locking periods
Deterministic transaction fee calculations prevent failed gas charges

Inconvénients & Considérations

Slower development cadence due to formal academic peer-review processes
eUTXO model requires paradigm shifts for smart contract developers
Lower total value locked (TVL) in DeFi compared to EVM ecosystems

Foire Aux Questions

Q: Qu'est-ce que Ouroboros?

Ouroboros is Cardano’s flagship Proof-of-Stake consensus mechanism based on peer-reviewed cryptographic proofs.

Q: Qu'est-ce que le eUTXO model?

eUTXO extends Bitcoin’s Unspent Transaction Output design to enable deterministic smart contracts with predictable execution costs.
