Cardano

Cardano is a layer-1 smart-contract blockchain founded in 2017 by Ethereum co-founder Charles Hoskinson and developed by IOG, the Cardano Foundation and Emurgo. It is distinguished by an academic, peer-reviewed approach, with protocol changes grounded in formal research before deployment. ADA is its native token, used to pay fees, stake for network security and participate in on-chain governance. Cardano aims to provide a scalable, secure platform for decentralised applications, with a deliberate, phased roadmap prioritising rigour over speed.

Cardano runs on Ouroboros, a peer-reviewed proof-of-stake consensus protocol. ADA holders delegate to stake pools or run their own to help secure the network and earn staking rewards, without lock-ups that remove liquidity. The chain uses an extended UTXO model, differing from Ethereum's account model, which affects how smart contracts and transactions are structured. ADA has a fixed maximum supply of 45 billion tokens, with issuance and a treasury funding ongoing development and governance through the emerging Voltaire on-chain governance system.

ADA's price reflects developer activity, adoption of decentralised applications, staking participation and delivery of roadmap milestones such as scaling and governance upgrades. Network growth, partnerships and broader demand for smart-contract platforms act as catalysts. The capped 45 billion supply and staking, which locks up a large share of tokens, influence circulating liquidity. ADA trades far below its 2021 peak near $3, and its price remains sensitive to overall crypto cycles and competition among layer-1 blockchains.

Cardano's deliberate, research-first pace has drawn criticism for slow delivery and comparatively limited DeFi and application activity versus rivals like Ethereum and Solana. Intense layer-1 competition, reliance on continued developer momentum and execution risk on governance and scaling are key concerns. ADA is volatile and trades well below prior highs, and broader regulatory uncertainty around staking assets adds risk.
