Taiko is a Layer 2 project built on Multi-Proofs aimed at addressing potential zkEVM bugs and enhancing Ethereum's scalability. Its core innovation is the BCR (Based Contestable Rollup) framework, which allows anyone to challenge block states and ensures network security through a competitive mechanism. Taiko launched on the mainnet on May 27 and has attracted attention from several well-known VCs and projects. Vitalik Buterin believes Taiko emphasizes the community and security of Ethereum L2 and is optimistic about its prospects. However, Taiko also has some drawbacks, such as a short launch time and tokenomics controversies. Additionally, the overall development of the zkEVM ecosystem is slow, while Op-based Layer 2s have already taken the lead in ecosystem building. Overall, Taiko is a promising project, but its future development requires further observation.
