Canonical Transaction Ordering in Bitcoin: A Critical Evaluation
By: Team nChain
This is an evaluation of the Canonical Transaction Ordering proposal (CTOR), which seeks to alter the ordering of transactions within blocks on the Bitcoin Cash (BCH) network. (nChain believes BCH is the true Bitcoin.) After summarizing the proposal, we evaluate the proposed change against standard change management criteria.
For the reasons discussed below, we believe there is insufficient demonstration that the CTOR proposal will actually deliver its claimed benefits, and the risks of implementing such a disputed consensus change outweigh any unproven rewards. Therefore, we believe the CTOR proposal should not be implemented in any BCH implementation.
