About Cardano
Cardano Price Data
Cardano (ADA) currently has a price of $0.16 and is down -6.16% over the last 24 hours. The cryptocurrency is ranked 20 with a market cap of $5.8B. Over the last 24 hours, it saw $285.2M of trading volume. The token has a circulating supply of 37.3B tokens out of a total supply of 45B tokens.
Cardano (ADA) is a decentralized platform that aims to provide a secure and scalable infrastructure for the development of decentralized applications and the execution of smart contracts. It utilizes a proof-of-stake consensus algorithm and incorporates scientific research and peer-reviewed methodologies to ensure sustainability and innovation.
Unique Features of Cardano:
Proof-of-stake consensus mechanism
Cardano uses a proof-of-stake consensus mechanism. Contrary to Bitcoin's proof-of-work approach, Cardano relies on proof of stake to validate transactions and secure the network. In a proof-of-stake system, validators or "stakeholders" are selected to create new blocks and validate transactions based on the amount of ADA they hold and are willing to stake. It is more energy-efficient compared to proof of work since it doesn't require the same level of computational power.
Scientific approach to development
Cardano claims to take a methodical and scientifically grounded approach. The development team consists of academics and researchers who apply peer-reviewed research and scientific principles to the development process.
The platform is built on a peer-reviewed proof-of-stake algorithm called Ouroboros, which has undergone rigorous testing and validation. This algorithm ensures the security and reliability of the Cardano network, making it resistant to attacks and vulnerabilities.
Another element of Cardano's scientific approach is formal verification. This involves using mathematical methods to ensure that the software system behaves as intended. By applying formal verification techniques to the smart contracts and protocols on the Cardano blockchain, the team minimizes the risk of bugs and vulnerabilities, making the platform more secure and trustworthy.
Built-in governance system
Cardano has a governance system that sets it apart from cryptocurrencies like Bitcoin. Unlike Bitcoin, where changes are typically proposed and implemented solely by developers, Cardano's governance system actively involves ADA token holders in decision-making. This means that ADA holders have the power to propose and vote on improvement proposals, creating a decentralized and democratic cryptocurrency governance model.
When was Cardano created or founded?
Cardano was founded in 2015. The idea for Cardano came about as an effort to address the shortcomings and challenges faced by existing blockchain platforms. Hoskinson envisioned a third-generation blockchain platform that would be more sustainable, scalable, and secure.
Who are the founders of Cardano?
The founders of Cardano are Charles Hoskinson and Jeremy Wood. Charles Hoskinson, a prominent figure in the cryptocurrency industry, co-founded Ethereum and currently serves as the CEO of IOHK (Input Output Hong Kong), the company behind Cardano. Jeremy Wood, a technology entrepreneur, has collaborated closely with Hoskinson on various projects.
One notable aspect of the founders of Cardano is their academic background. Charles Hoskinson pursued analytic number theory before venturing into the cryptocurrency space, while Jeremy Wood possesses a solid foundation in mathematics and computer science.

Frequently Asked Questions
Voltaire is Cardano’s governance phase, activated through the Chang hard fork (2024) and further extended by the Plomin hard fork. It introduced on-chain governance via CIP-1694, allowing ADA holders to vote on protocol parameter changes, treasury withdrawals, and constitutional amendments. The Plomin fork gave full voting power to delegated representatives (DReps) and the Constitutional Committee, completing the transition away from IOG/Emurgo/CF controlling upgrades.
Hydra is Cardano’s isomorphic state channel protocol. “Isomorphic” means the off-chain Hydra head runs the same Plutus smart contract logic as the main chain, enabling arbitrary off-chain computation with the same programmability. Hydra heads are opened between a fixed set of participants, process transactions off-chain at theoretical throughputs of 1M+ TPS per head, then settle final state on-chain. The limitation: it is not a general-purpose rollup; it requires predefined participants and is better suited for specific use cases (payment channels, gaming, auctions) than open user access.
DReps (Delegated Representatives) are on-chain entities to whom ADA holders delegate their voting power. ADA holders can either vote directly or delegate to a DRep whose governance philosophy aligns with theirs. This is liquid democracy: the ability to delegate and undelegate at any time, with delegation following stake. The system also includes the Constitutional Committee (a 7-of-9 multisig-style body) as a constitutional check on governance actions.
Cardano’s development philosophy routes all protocol changes through academic peer review before implementation. IOG (Input Output Global) publishes papers on Ouroboros (PoS consensus), Plutus (smart contract language), and other components in formal academic venues. The tradeoff is slower iteration velocity compared to Ethereum’s EIP process or Solana’s move-fast approach. The thesis: correctness and formal verification reduce the probability of catastrophic bugs. The counterargument: the bottleneck has historically been developer adoption and ecosystem velocity, not security.
The Cardano Constitution is an on-chain document that governs how the network can be changed and what values guide governance decisions. Ratification required a global Constitutional Convention with representatives from across the ecosystem and a 75% supermajority vote. It acts as a meta-governance layer: proposed governance actions must be compatible with the Constitution or they can be vetoed by the Constitutional Committee.
