One-Shot Replace-By-Fee-Rate

tl;dr: we can solve Rule #3 transaction pinning attacks by simply replacing based on fee-rate, if the old transaction wasn't going to be mined in the next block or two, and the new transaction will be.

This _is_ incentive compatible, because it makes more sense to make money now with a high fee rate transaction than to favor a transaction of lower fee rate that may never even be mined.

What is full-RBF? Why is it good for multiparty protocols like conjoin? Why is it good for wallets and miners? And why do a small minority hate it with a passion?

(we all gotta take a break from ordinal drama you know)

Not good.

We really need miners to move off Foundry to smaller pools.

Luxor mined a block with four full-rbf replacements at once: https://web.archive.org/web/20221224215544/https://fullrbf.mempool.observer/

Two from my OTS calendars (including a $165 fee). And two others that I didn't create.

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.
