Solidity uint to bytes
WebApr 12, 2024 · 构建固定大小字节数组Solidity中固定大小的字节数组可以通过关键字“byte”来实现。例如:可以使用bytes1,bytes2,....bytes32来声明某一个数组具有多少字节的存储空间。需要注意的是我们经常看到的“byte”就是“bytes1”。 Web加密哈希函数是一种算法,它以任意数量的数据作为输入并生成固定大小的加密文本。即使输入的微小变化也会产生完全不同的输出。以太坊使用 Keccak 进行散列,这与 SHA_256 相似但不同。对于工作量证明,它使用了一种名为。中,创建了一个智能合约以将字符串作为输入并给出 8 位哈希作为输出。
