$ETH Yitai is a decentralized blockchain platform that allows developers to create smart contracts and decentralized applications. In 2015, Yitai introduced the concept of programmable blockchain, enabling complex transactions beyond simple currency transfers. Its native cryptocurrency, Yitai, powers these applications and pays transaction fees. Yitai has undergone significant upgrades, including the transition to Yitai 2.0, which improves scalability and reduces energy consumption through a proof-of-stake consensus mechanism.
