The blockchain implementation practice generally chooses Ethereum smart contract development, but the existing smart contract practice projects have many vulnerabilities in security.
After summarizing many digital currency theft incidents caused by smart contract vulnerabilities, we found that it is not the smart contract technology itself that has a problem, but a loophole in the actual writing. So how do we prevent risks in the actual development?
The Hiblock blockchain community organized the 6th blockchain technology salon sharing event in Shanghai on the afternoon of May 19th . For this event, we invited Shi Yimin, the author of the "Blockchain Programming Guide", to share common vulnerabilities of smart contracts. And programming security skills .
