On September 13th, Alex Gluchowski, CEO of ZKsync developer Matter Labs, announced the launch of the ZKsync governance system yesterday. Alex said that the governance system is not multi-signature. "All planned upgrades are initiated directly on the chain by the community of more than 370,000 ZK token holders, not by a foundation or a small group of trusted actors." Solana Toly disputed the article, saying that although ZKsync claims not to be a multi-signature system, it is still based on the honest majority assumption, which means 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 enough validators reach consensus, a single full node of Circle (the issuer of the USDC) is able to reject invalid state transitions, thus protecting the system from malicious behavior. ZKsync's "professional security committee" may face legal risks because if enough committee members are ordered by a US bankruptcy judge, they may be forced to place all cross-chain assets under the control of a bankruptcy trust.
