5/ Blockchains use two primary forms of cryptography: hashing & asymmetric encryption. From these come the ability to generate/verify digital signatures, validate blocks, & store data in the ledger efficiently.
Let's look at each of these cryptographic functions in blockchains.
5/区块链使用两种主要的加密形式：散列和；非对称加密。由此产生了生成/验证数字签名、验证块和；有效地将数据存储在分类账中。
让我们看看区块链中的每一个加密功能。
