Canonical Transaction Ordering


1. definition

Canonical Transaction Ordering - CTOR for short - is a rule on Bitcoin Cash (BCH) which requires transactions within each block to be ordered by their transactions IDs.

This ordering enforcement and consistency allows for enhanced compression techniques, and faster/simpler transaction inclusion/exclusion lookups. This is one improvement of many which aim to enable Bitcoin Cash (BCH) to be a worldwide currency.

CTOR was enabled on Bitcoin Cash (BCH) during the scheduled November 2018 hardfork.
