Ethereum Layer 2 Taiko goes live on mainnet

-------------------------------------------

Ethereum-based rollup Taiko has launched on mainnet after being in development since 2022 and undergoing seven testnets.

Ethereum co-founder Vitalik Buterin proposed the first block on Taiko's mainnet, with metadata containing the names of every core contributor to Taiko.

Taiko is a based rollup — a rollup based on the Ethereum mainnet, instead of creating a completely separate blockchain. This method allows Taiko to leverage the security and decentralization of Ethereum while improving scalability and reducing transaction costs by processing transactions offchain and aggregating them into a single batch on the Ethereum mainnet.

At the initial stage, Taiko rollup protocol contracts on Ethereum are controlled by a multi-signature agreement. The protocol initially requires SGX proof, with plans to move to requiring 50% of blocks to use ZK* proof as part of a long-term scaling and security strategy.

SGX proofs are a type of proof that uses Intel Software Guard Extensions (SGX) technology to protect the integrity and security of data and processes within Taiko's network. This helps ensure that activities and transactions on the network are protected from attacks and unwanted changes, while enhancing the privacy and security of the system.

“We are extremely excited to finally launch Taiko on the Ethereum mainnet,” said Taiko co-founder and CEO Daniel Wang. “After a long period of effort, we are pleased to provide the most secure technology to scale Ethereum.”

Furthermore, Taiko incorporates a type 1* zero-knowledge virtual machine designed to emulate the Ethereum architecture and includes a multi-proof proof system. This system enhances security by allowing multiple types of evidence to be submitted and contested.
