Hi devs, a discussion started how it would be possible to ensure that two transactions will be forged, i.e. one will only be forged if the other is forged, too.
The idea to use a "always-valid" EC parameter was brought up, however my understanding is that this would not help, i.e. it would be valid on both forks if it happened that one TX got bundled in one block and the other a block later on a fork. So my understanding is that "always-valid" EC parameter would be equally helpful as no EC parameter at all.
What would be a good design pattern to ensure that two transactions are forged together? Phasing?
