In order to reduce the risk of security vulnerabilities, the platform should choose a Turing-complete language, which can achieve anything that the underlying system can do. However, the complexity of Turing-complete languages often leads to bugs and vulnerabilities, so developers need to fully understand common issues in smart contract programming to avoid potential security risks."}]}],"pr":"3201df0614f35baba81bb5c9bcb18bbf870a00e86adbf3a39291e1d131097424"}
