Cardano
Description
By Anatol Antonovici:
"Cardano is a decentralized, open-source blockchain network that launched in September 2017. Like Ethereum, Cardano supports smart contract functionality (self executing computer programs) but plans to take them to the next level by ensuring higher speeds and broader interoperability. The hope is it will make them more functional and accessible than Ethereum smart contracts so that anyone – not just developers – can create their own decentralized applications.
Despite the project still being in development, Cardano is frequently touted as an “Ethereum killer” because it seeks to improve upon the second-largest cryptocurrency’s current infrastructure. These improvements include significantly cheaper fees, better scalability and higher transaction throughput and speed than what is currently offered by Ethereum’s 1.0 blockchain."
