I’ll probably run a fork-observer instance with a Bitcoin Core node and a BIP-110/300 node side by side. I’ll likely also live-stream this in some capacity.
Monitoring for transaction replay across the forks, assuming there are blocks for them, should be interesting as well. Not sure if I’ll get to this.
For the BIP-110 fork, someone might attempt to publish data-embedding transactions into the chain around the fork height or shortly after. Especially on the BIP-110 side. It would be good to have coverage of this, even if it’s not given that this will happen.
