通过本文我们可以清楚的知道自己的的铭文在哪里，以及它是以什么样的形式构建的。
|
||
|
||
我们随便在Ordinals的浏览器上找到一个Inscription交易，比如2c69dcbfed33a02154e45285db2494aa3a9083ff39f31e90edeecd4791731c32。
|
||
|
||
获取到这个交易的rawtransaction（通过btc.com或其他比特币浏览器网站就可以获取到）是这样的

下面我们就来分析一下这些数字都是什么意思。开始之前我们需要先介绍一些编程的基础概念：
|
||
|
||
位（bit）：计算机处理的最小二进制单位，即0或1
|
||
字节（byte）：每个字节由8个bit组成，0001 0001
|
||
十六进制（hex）：每数到16就往前进一位的计数方式，19的数字和十进制一样，1015的标记分别用abcdef标识，比如3a换成十进制就是3*16+10=58。之所以用十六进制，是因为十六进制的f换成二进制刚好是1111，也就是说一个字节的内容可以用两个十六进制字符完整表示。
|
||
上面的rawtransaction中也是由许多个十六进制的数字表示的，其中每两个可见字符就是一个十六进制字节。
|

||
OP_ENDIF 1 68
|
||
我们可以看到中OP_FALSE开始就完全是Ordinals协议定义的内容了，这里面就存储了铭文的知己内容。这里的内容是纯文本，如果是图片的话，Inscription字段就会很长。
|
||
|
||
好了，现在任何一个Ordinals的交易你也会分析了，可以不用浏览器也知道铭文的内容了，虽然你并不想自己去解析
