Currently about 20% to 30% of hash power is running full-rbf – notably AntPool – so you no longer need to set nSequence. Just set mempoolfullrbf=1 in your bitcoin.conf on a well-connected Bitcoin Core node and publish it. You can also publish it via https://blockstream.info/tx/push and https://mempool.nixbitcoin.org/tx/push both of which support full-rbf.

nsequence what?

That's like saying if I want to increase the volume on my android i need to do something like:

VolumeManager.setVolume(0.5);

Um ... no. Well, technically that is correct. Somewhere, that is what the app I am using is doing under the hood, but I don't need to do setVolume() call to change the volume. I press something somewhere, and it does a setVolume().

Some thing here, for RBF. So the UX to do this will depend on what app I am using to send or spend.

These slides are great.

Looking forward to more of your content.

Going to need an update soon:

[bitcoin-dev] Full-RBF testing: ≥31% of hash power, ≥4 pools, is mining full-RBF #226399 https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2023-August/021890.html
