WebApr 29, 2024 · Oyente uses symbolic execution on EVM bytecode to identify vulnerabilities. Some of Oyente’s detection schemes are not perfect, and the vulnerabilities involved are not comprehensive enough. Compared to some other static analysis tools, Oyente needs to cost more time executing smart contracts in the virtual Ethereum environment. WebJun 11, 2024 · While the EVM does have some flaws (for example, not being able to poll sites outside the blockchain), it is a fine piece of engineering in that it can accurately tabulate memory usage in form of decreasing gas, is extremely efficient in how it uses memory (although it still cant really do much), and most importantly, it is entirely deterministic …
