Notes

• Construct worst case, forcing EVM to load large contracts to increase proving burden.
• Use EXTCODESIZE bytecode to force EVM to load contract bytecode, increasing ZK circuit complexity. EXTCODECOPY is similar.
• This operation consumes the least gas (~408 gas/KB), but is very complex in ZK circuits.
• This repo provides tools to construct such worst cases.

• 构造最差情况(worst case)，迫使EVM加载大型合约来增加计算负担。
• 使用EXTCODESIZE字节码迫使EVM加载合约字节码，增加ZK电路的复杂度。EXTCODECOPY也是类似的。
• 该操作消耗最小的gas（~408 gas/KB），但在ZK电路中非常复杂。
• 该代码库提供了构造这类最差情况的工具
