According to Techub News, Google Cloud has become the latest member of the Guardian Network, the security system of Wormhole. As a Guardian node, Google Cloud's infrastructure will enhance the security of decentralized networks. The two parties will also accelerate Wormhole's ZK roadmap and optimize multi-chain security. The focus of the cooperation includes strengthening fast, low-cost and trustless cross-chain message verification, and studying the addition of a trustless ZK verification mechanism outside of Wormhole Guardian.
