Taiko, an Ethereum Layer 2 protocol, has been deployed on the Ethereum mainnet after two years of development. The launch marks a significant milestone in Ethereum's history, as Taiko is the first Layer 2 solution with permissionless sequencing and proving. Vitalik Buterin proposed the first mainnet block for Taiko. Backed by Wintermute Ventures, Taiko is an open-source, permissionless Ethereum-equivalent ZK-Rollup designed to enhance Ethereum's scalability while maintaining its core properties. Taiko operates through community-driven governance, ensuring that all operations are managed by the community. Co-founder and CEO Daniel Wang expressed excitement about delivering what they believe is the most secure technology to scale Ethereum, stating, "It’s been a long time in the making and we’re beyond thrilled to deliver what we think is the most secure technology to scale Ethereum."
