> A satpoint may be used to indicate the location of a sat within an output.
> A satpoint consists of an outpoint, i.e., a transaction ID and output index, with the addition of
> the offset of the ordinal within that output. For example, if the sat in question is at offset 6
> in the first output of a transaction, its satpoint is:
> `680df1e4d43016571e504b0b142ee43c5c0b83398a97bdcfd94ea6f287322d22:0:6`
