In development with IOHK, Cardano (ADA) has created an open-source, patent-free smart contract blockchain. It claims to be the first to evolve out of a scientific philosophy, presenting more advanced features than any protocol yet developed. This collaborative effort is progressing distributed systems, mechanism design and cryptography. Ouroboros, their groundbreaking Proof of Stake algorithm, is to be the first of its' kind based on the Haskell code. The strength and resilience of this product should allow for a secure investment. Cardano has developed a team of expert engineers and researchers, including Charles Hoskinson, a former Ethereum CEO.
