The concept of switching to a canonical transaction ordering rule for the Bitcoin Cash blockchain isn't ready to be the best solution, according to one Reddit user.

Canonical Transaction Ordering for Bitcoin
Abstract: We propose to replace the topological transaction ordering rule of Bitcoin by the canonical transaction ordering rule, where transactions are expected to be sorted against their transaction identifiers within a block. This change eliminates an entire class of scalability challenges for Bitcoin in order to process very large blocks. This change also delivers two compelling use cases. First, it allows to produce compact proofs of transaction inclusion/exclusion, making chainless apps more capable. Second, it gives a newer degree of control to Bitcoin participants to localize their transaction within blocks.
