A New Transaction Ordering Rule Proposed for Bitcoin Cash

Joannes Vermorel (Lokad), Amaury Séchet (Bitcoin ABC), Shammah Chancellor (Bitcoin ABC), and Tomas van der Wansem (Bitcrust) have published a new paper that proposes to change the current topological transaction ordering rule within the BCH network. The paper called ‘Canonical Transaction Ordering for Bitcoin’ argues that a canonical ordering process would be more efficient and allow for better scaling. Currently, consensus rules process transactions in a list form where remote peers forward transactions to their neighbors. The way it works right now the list must be topologically sorted, but if the rule was changed to a canonical method that works with blocks as a set, as opposed to a list, it enables BCH to process very large blocks.
