最近FTX爆了，据称是挪用了用户资金！不管是什么技术，最后还是回到了灵魂拷问：利和义，你取哪样？！吃瓜群众们又在那想验证资金的办法，怎么自证清白之类的。其实我想说，这只关乎人性，无关技术。如果真的关乎技术，那应该有N种办法。 这里提这N种办法中的一种：merkletree证...

把节约gas的几个方法测试了下，蛮有效的。以前看起来有些多余的操作其实是另有深意啊。比如常见的语句uint _arr = arr[i]，直接写arr[i]不是更直观么，为什么非要定义一个变量呢？！现在终于揭晓了谜团：原来是为了节约gas啊！ 案例集 中把这些方法都总结了，我...

前不久研究了下重入攻击的玩法，里面有个重要的特性：合约的fallback()函数。 fallback是合约的底层函数，在没有其它函数匹配的情况下会执行。这个特性导致了重入的风险性，但在另一方面，合约的升级性也会用到这一特性。这充分体现了一物的两面性：是好是坏取决于你！ 由于...

在执行智能合约时如何确定合约的正确执行结果呢？在得到正确的结果后再执行一系列的操作。比如现实中，只有你已确定付款后才能拿走商品一样，智能合约只能得到正确的结果才能进行下一步。 要起得到确定的结果，一般有两种办法：一种是轮询事件，另一种是直接分析得到的结果 。例如：let r...

目前市场上流行的NFT标准是ERC721，而这个标准和ERC20类似，都有一些标准的函数和库。并且，一般只要按照OpenZeppelin的标准来就行。比如今天要铸造的NFT就可以直接引用OpenZeppelin的库，自己要写的方法估计也就不到10行。直接来看下： // SP...

我们在获取合约中数组时一般是采用的遍历的方法，这个好像没什么太大问题。但是如果提供节点服务的供应商对访问有限速，那这种遍历的方法就挺蛋疼的。现在我看很多前端是采用的multicall的方法，就是直接一次到位，获取所有的数据。这个遍历的过程是直接在合约层就完成，节点只需访问一...
