Baseine地址中的地址的Base58编码/解码

优化的地址为22个字节,其格式如下:

• 第一个字节是一个标记,对于隐式(tz)来说是00,对于原始(KT)来说是01

如果第一个字节为00,并且我们正在使用隐式(tz)地址,则:

• 第二个字节描述曲线,因此也描述了前缀.这是00(ed25519/tz1),01(secp256k1/tz2)或02(p256/tz3)
• 剩余的20个字节是地址

如果第一个字节为01,并且我们正在使用原始(KT)地址,则:

• 接下来的20个字节是地址
• 最后一个字节是00缓冲区(将长度填充到22个字节)

要将优化的表单转换为地址,可以使用eztz并执行以下操作:

 function getAddressFromOptimized(hex){
  var address, prefix;
  if (hex.substring(0,2) == "00") {
    if (hex.substring(2,4) == "00") prefix = eztz.prefix.tz1;
    if (hex.substring(2,4) == "01") prefix = eztz.prefix.tz2;
    if (hex.substring(2,4) == "02") prefix = eztz.prefix.tz3;
    address = hex.substring(4,44);
  } else if (hex.substring(0,2) == "01"){
    prefix = eztz.prefix.KT;
    address = hex.substring(2,42);
  }
  return eztz.utility.b58cencode(eztz.utility.hex2buf(address), prefix);
}
console.log(getAddressFromOptimized("011cd5f135e80fd8ebb6e43335b24ca6116edeba6900")) 
 

此处记录了格式: http://tezos.gitlab.io/mainnet/api/p2p.html#contract-id-22-bytes-8-bit-tag

Optimized addresses are 22 bytes, which follows the following format:

• The first byte is a tag, either 00 for implicit (tz) or 01 for originated (KT)

If the first byte is 00 and we are working with an implicit (tz) address, then:

• The second byte describes the curve and therefore the prefix. This is either 00 (ed25519/tz1), 01 (secp256k1/tz2) or 02 (p256/tz3)
• The remaining 20 bytes is the address

If the first byte is 01 and we are working with an originated (KT) address, then:

• The next 20 bytes are the address
• The last byte is a 00 buffer (to pad the length to 22 bytes)

To convert the optimized form to an address, you can use eztz and do something like this:

function getAddressFromOptimized(hex){
  var address, prefix;
  if (hex.substring(0,2) == "00") {
    if (hex.substring(2,4) == "00") prefix = eztz.prefix.tz1;
    if (hex.substring(2,4) == "01") prefix = eztz.prefix.tz2;
    if (hex.substring(2,4) == "02") prefix = eztz.prefix.tz3;
    address = hex.substring(4,44);
  } else if (hex.substring(0,2) == "01"){
    prefix = eztz.prefix.KT;
    address = hex.substring(2,42);
  }
  return eztz.utility.b58cencode(eztz.utility.hex2buf(address), prefix);
}
console.log(getAddressFromOptimized("011cd5f135e80fd8ebb6e43335b24ca6116edeba6900")) 

The format is documented here: http://tezos.gitlab.io/mainnet/api/p2p.html#contract-id-22-bytes-8-bit-tag

我相信您应该能够使用Stephen Andrews eztz 库来访问各种工具js环境

我推测功能是一个使用 KT前缀

   b58cencode: function (payload, prefix) {
    const n = new Uint8Array(prefix.length + payload.length);
    n.set(prefix);
    n.set(payload, prefix.length);
    return library.bs58check.encode(new Buffer(n, 'hex'));
  }
 

I believe you should be able to make use of Stephen Andrews eztz library to access various tools from a js environment

I would speculate the function is this one where you use the KT prefix

  b58cencode: function (payload, prefix) {
    const n = new Uint8Array(prefix.length + payload.length);
    n.set(prefix);
    n.set(payload, prefix.length);
    return library.bs58check.encode(new Buffer(n, 'hex'));
  }
