txsort
Package txsort provides the transaction sorting according to BIP 69.
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.
