Eliminating finalize step revisited

But the MWC protocol still has a similar usability hurdle: a long delay can be caused by the recipient to complete the transaction.

While MW might have two such delays, it’s only the latter that introduces uncertainty as to whether the transaction will complete.

The benefits of a 2-step protocol were discussed at length here: Eliminating finalize step

From my understanding, it has been considered to be an improvement.

My goal was to provide a 2-step protocol that does not compromise on security. Whether the costs are worth the benefits is not something I can answer.
