The technology underpinning Cardano’s ADA token was designed by leading experts, academics and cryptographers over the last two years, drawing on the best features of existing cryptocurrencies including Bitcoin, Ripple and Ethereum. Crucially, it is the first blockchain to use a provably secure, proof-of-stake algorithm – the only one to have been academically peer reviewed by leading cryptographers through its acceptance to Crypto 2017, the world’s top cryptography conference.
