[Solana co-founder questions ZKsync's claim that the governance system is not multi-signature, believing that the latter has centralization risks] On September 13, yesterday, Alex Gluchowski, CEO of ZKsync developer Matter Labs, announced the launch of the ZKsync governance system. Alex said that the governance system is not multi-signature, "All planned upgrades are initiated directly on the chain by a community of more than 370,000 ZK token holders, rather than by a foundation or a small group of trusted actors." Solana co-founder Toly questioned the article. Although ZKsync claims that it is not a multi-signature system, it is actually still based on the honest majority assumption, which means that it is essentially similar to a multi-signature system. Toly further stated that unlike Solana, ZKsync's governance system has potential centralization risks. In Solana, even if there are enough validators to reach a consensus, a single full node of Circle (the issuer of USDC) is able to reject invalid state transitions, thereby protecting the system from malicious behavior. ZKsync’s “Professional Security Committee” could face legal risk because if enough committee members are subject to orders from a U.S. bankruptcy judge, they could be forced to place all cross-chain assets under the control of a bankruptcy trust.
