Ethernaut CFT的触发
目录智能合约的几个方向ethernaut puzzles汇总ethernaut puzzles 案例类型解析solidity语言特性与区块链本身的特性的相关点合约之间的相互调用第三方合约的使用gas消耗攻击业务逻辑的创新与新的可能性合约代理更新机制Bytescode级别个人看法其他资料Ethernaut资料相关链接1 智能合约编程的几个方面自从开始接触智能合约，有关智能合约编程的几个方面一直让我印象深刻，1 是安全，这可以从以太坊经典事件DAO攻击以及此起彼伏的链上黑客攻击体会安全性在整个行业的重要性；2 是gas优化，对于gas优化可能现在由于不是牛市，以及layer2层逐渐完善导致的gas费降低，对这方面的关注在变淡，但我认为gas是基础，某些情况下其重要性可能会凸显，我猜想可能类似于量化投资中对于速度的要求，如果未来随着用户量的指数级上升，将会有可能再次引起人们对于gas的关注，另外一方面，智能合约每一步的运行最终都会转化为opcode,而每一个opcode都会消耗一定量的gas，这是整个EVM的运行的基础，也是了解以太坊核心的基础。3 则是智能合约之间的复杂调用关系，很多...

The uniswap first appeared in my world, which made me astonishing and excited. The back-end services behind the uniswap, which anyone can interact with, aren't based on centralized services. The tries involving the dex before uniswap have existed for a long time, but the user experiences、user activities、transaction amount of these tries have lived in a limited range. When I see the gelto(https://app.gelato.network/), my first thought is that bring the timed tasks into on-chain. All these...
