representation, so the serialized transaction ID will be in the opposite order.

### Example

An example of a child inscription of
`000102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1fi0`:

```
OP_FALSE
OP_IF
  OP_PUSH "ord"
  OP_PUSH 1
  OP_PUSH "text/plain;charset=utf-8"
  OP_PUSH 3
  OP_PUSH 0x1f1e1d1c1b1a191817161514131211100f0e0d0c0b0a09080706050403020100
  OP_PUSH 0
  OP_PUSH "Hello, world!"
OP_ENDIF
```

Note that the value of tag `3` is binary, not hex, and that for the child
inscription to be recognized as a child,
`000102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1fi0` must be
spent as one of the inputs of the inscribe transaction.
