AVA Labs co-founder and Cornell University professor Emin Gün Sirer said on the social media platform that hackers have recently stolen about 25 million US dollars of tokens from the Dapp of the decentralized loan agreement Lendf.Me. The problems and the year The reentry bug of The DAO is similar. In this regard, Professor Sirer emphasized, “This kind of problem is local to Ethereum, and for Dapp, it is difficult to determine whether assets represented by opaque bytecode are subject to reentry. Therefore, encrypted assets should be able to prevent reentry. Deployment in the way. In the design of AVA, the asset is the “First Class Object” (First Class Object), the behavior of the asset is set by the system, no code analysis is needed to determine whether sending an asset will result in the Dapp ’s assets being drawn go. “
