Odaily News Polygon Labs developer relations engineer Jarrod Watts said that the Blast contract is an upgradeable contract controlled by 3/5 multi-signatures. The 5 addresses are all anonymous new addresses. It is possible for Blast to perform code upgrades through multi-signatures and steal them immediately. Funding, while many other Layer 2 solutions currently have the same functionality including Arbitrum, Blast (currently) is not Layer 2, but simply a smart contract that accepts user funds and puts the funds into protocols such as Lido middle. There is no testnet, no transactions, no bridges, no rollups, and no transaction data sent to Ethereum. If the 3/5 multisigs that control the contract do not do the right thing in the future, users will not be able to withdraw the money deposited into the Blast contract at any time. In this regard, SlowMist founder Yu Xian said that Blast’s contract is indeed an upgradeable contract as Jarrod Watts said. The control rights belong to a 3/5 multi-signature (I don’t know who the five people are) and there is no time lock. If you want to run away, you must either sign more and upgrade a malicious logic contract, or enableTransition and set up a malicious mainnetBridge. Currently, except for the contracts issued on Ethereum, Blast is a fission gameplay of the centralized Web2 project, but it is endorsed by several well-known institutions. Users still trust projects endorsed by institutions.
