What is Cardano and how is it different from other blockchains?

Cardano was built with a philosophy that sets it apart in the industry: every protocol design decision should be grounded in peer-reviewed academic research before implementation. Founded by Ethereum co-creator Charles Hoskinson, it is developed by IOHK with formal verification methods borrowed from computer science and mathematics. This methodical approach has made Cardano slower to ship features than competitors - smart contracts did not arrive until 2021 but proponents argue it produces a more provably secure foundation. ADA is the native token. Cardano has focused significant efforts on financial inclusion in Africa, building identity and payment infrastructure in regions underserved by traditional banking.
