解析 A。区块链中的“hash function”(哈希函数)指的是“a mathematical algorithm”(一种数学算法)。B 选项“a data structure”是“一种数据结构”;C 选项“a network protocol”是“一种网络协议”;D 选项“a storage method”是“一种存储方法”。
in a different hash value. Similarly, in a blockchain system, any change made to a block, such as a transaction, will result in a different hash value. If we take the example of blockchain use in cryptocurrencies, transactions of varying lengths are run through a given hashing algorithm, ...
在散列表中,每个位置对应一条链表,所有散列值相同的元素都放到相同位置对应的链表中。 In terms of chain based technology,different countries,regions,industries and even the same industry have different standards,which will lead to the slow development of the application of blockchain technology.The blockc...

2. SHA-1(Secure Hash Algorithm 1):输出160位,比MD5安全一些,但已被证明可被碰撞,逐步淘汰中。 3. SHA-256:输出256位,是比特币区块链使用的标准算法,当前非常常见、安全。 4. Keccak(SHA-3):新一代安全哈希算法,用于对抗未来的密码学攻击。
one must also modify the subsequent block. However, changing that block also changes its hash value, necessitating changes to the next block, and so on. Repeating this process for all linked blocks is practically impossible, especially given the vast number of blocks in blockchains like Ethereum...
The hash algorithm maps binary values of any length to shorter fixed length binary values,which are called hash values.Hash value is a unique and extremely compact numerical representation of a piece of data.If a clear text is hashed and even one letter of the paragraph is changed,the subsequ...

That’s it. And in the same spirit, hashing has a process behind it, known as the hash function, an algorithm that takes specific data as input and produces a hash value at the other end. Even the slightest change in the input data will result in a different hash value. ...
