When cardano hydra?

When Cardano Hydra went live on October 1st, it was the first time in history that a blockchain platform had been launched that allowed for the creation of smart contracts with multiple programming languages. This was a huge step forward for the blockchain industry, as it made it easier for developers to create contracts and decentralized applications on the Cardano platform. The launch of Cardano Hydra also marked an important milestone for the Cardano community. For the first time, users were able to vote on proposals and governance issues using their ADA tokens. This gave people a voice in how the Cardano platform was developed, and allowed them to have a say in its future.
