Excellent video.

Interesting! Foundry USA mined a full-rbf double-spend, with a few minutes between tx #1 and tx #2: https://web.archive.org/web/20221221022035/https://fullrbf.mempool.observer/

My best guess is this has something to do with unconfirmed inputs. My stock v24.0 node saw both tx #1 and tx #2 at the same time initially, but rejected the latter for spending an unconfirmed input. Then a few minutes later, it accepted tx #2 once the input confirmed.

I have two rented VPS servers running full-rbf nodes that were previously in Mykolaiv, Ukraine, quite close to the front lines in Kherson.

The hosting company finally gave up and moved their whole operation to a Kyiv data center this weekend. Russia has been trying to destroy the entire Ukrainian power grid for two months now; wouldn't be surprised if that hosting company can't get enough diesel fuel in Mykolaiv due to demand by other critical services.

Sad.

Better than I expected.

Interesting! A full-rbf doublespend just got mined by... a miner on P2Pool!

I didn't even know P2Pool still existed. And it kinda doesn't: according to https://web.archive.org/web/20201029044054/http://p2p-usa.xyz:9334/static/ the expected time between blocks right now is 3.2 years. Looks like the last block was 2 years ago.

Seems like the particular P2Pool miner that found the block had a high minimum fee, as the block only contained the high-fee parts of the mempool: https://miningpool.observer/template-and-block/00000000000000000001f6fc9422b5e1babc73f135d4a2ce3550494f54b601ac

Full-RBF Peering Bitcoin Core v24.0.1 is released.

tl;dr: this ensures you're connected to other full-rbf nodes, by advertising a FULL_RBF service bit, and connecting to four additional nodes advertising that service.

(Yes I know they're all imported school buses; that's the first one I've seen where they hadn't painted over which school system it was from)

Neat: that bus has travelled 4000km from a Kentucky school system to serve as a chicken bus in Guatemala.

TIL Guatemala has a _lot_ of Taco Bells.
