Address介绍

[英]A Bitcoin address looks like 1MsScoe2fTJoq4ZPdQgqyhgWeoNamYPevy and is derived from an elliptic curve public key plus a set of network parameters. Not to be confused with a PeerAddress or AddressMessagewhich are about network (TCP) addresses.

A standard address is built by taking the RIPE-MD160 hash of the public key bytes, with a version prefix and a checksum suffix, then encoding it textually as base58. The version prefix is used to both denote the network for which the address is valid (see NetworkParameters, and also to indicate how the bytes inside the address should be interpreted. Whilst almost all addresses today are hashes of public keys, another (currently unsupported type) can contain a hash of a script instead.
[中]比特币地址看起来像1MSSCOE2FTJOQ4ZPDQGQYHGEWEONMYPEVY，由椭圆曲线公钥加上一组网络参数派生而来。不要与关于网络（TCP）地址的对等地址或AddressMessage混淆。
标准地址是通过获取公钥字节的RIME-MD160散列、版本前缀和校验和后缀，然后将其文本编码为base58来构建的。版本前缀既用于表示地址有效的网络（请参阅NetworkParameters），也用于指示如何解释地址中的字节。虽然目前几乎所有地址都是公钥哈希，但另一个（当前不支持的类型）可以包含脚本哈希。
