Tezos is a blockchain network that’s based on smart contracts, in a way that’s not too dissimilar to Ethereum. The big difference is Tezos aims to offer infrastructure that is more advanced — meaning it can evolve and improve over time without there ever being a danger of a hard fork. This open-source platform also bills itself as “secure, upgradable and built to last” — and says its smart contract language provides the accuracy that is required for high-value use cases.
