Cardano is a groundbreaking proof-of-stake blockchain network, being developed into a decentralized application (DApp) development platform with a multi-asset ledger and verifiable smart contracts. Built with the rigor of high-assurance formal development methods, Cardano aims to achieve the scalability, interoperability, and sustainability needed for real-world applications. Cardano is designed to be the platform of choice for the large-scale, mission-critical DApps that will underpin the economy of the future. Based on peer-reviewed academic research, Cardano has an ethos of openness and transparency. All of the research and technical specifications that underpin Cardano are publicly published, and all Cardano development activity is made available to the public. Cardano is designed by a global team of experts who are leaders in disciplines ranging from distributed systems to programming languages and game theory and is jointly developed by IOHK and partners. IOHK develops the technology, the Cardano Foundation is responsible for supervising development and promoting Cardano, while Emurgo drives commercial adoption. While we are building Cardano, we are merely custodians. When the network is fully decentralized it will belong to the community, and it will be the community who decide its future through advanced governance features.
