Package txsort provides the transaction sorting according to [BIP 69](https://github.com/bitcoin/bips/blob/master/bip-0069.mediawiki).
|
||
|
|
|
||
|
|
BIP 69 defines a standard lexicographical sort order of transaction inputs and
|
||
|
|
outputs. This is useful to standardize transactions for faster multi-party
|
||
|
|
agreement as well as preventing information leaks in a single-party use case.
|
||
|
|
|
||
|
|
The BIP goes into more detail, but for a quick and simplistic overview, the
|
||
|
|
order for inputs is defined as first sorting on the previous output hash and
|
||
|
|
then on the index as a tie breaker. The order for outputs is defined as first
|
||
|
|
sorting on the amount and then on the raw public key script bytes as a tie
|
||
|
|
breaker.
|
||
|
|
|
||
|
|
A comprehensive suite of tests is provided to ensure proper functionality.
