So, I today listened to @openoms on the TFTC Podcast : https://anchor.fm/tales-from-the-crypt/episodes/155-Openoms-eddai0

It was great to hear in-depth discussion of Joinmarket :) I wanted to add several points, some just personal opinions, others corrections:

On probably the biggest question the hosts were asking: "what is the economic incentive for makers, why are fees low, is it easy to Sybil", here are several thoughts of mine:

* The market-arrived price has settled in the 0-1000 sat /maker for lower value coinjoins .. (1/n)

We had a nice privacy "Socratic" going over details of Payjoin. Thanks @michaelfolkson for organizing.
(Jitsi honestly performed pretty well I would say. we had around 10 participants and maxed out a bit higher, no really bad issues I could see). Good crowd, too.

Livestream was mirrored on youtube:

Nadav Kohen's payment points blog post series at suredbits is well worth a read. They're mercifully short compared to mine (lol) and the first one in particular I think does an excellent job of conveying, in a condensed form, the rather confusing but exceptionally powerful idea of multi-hop locks with discrete log.

A new blog post on the single-signer ECDSA adaptor mentioned last few days:

Many months later, after some discussions with .. some people, I see another aspect to this which is actually very useful and I had a total blind spot to it.

The fact that adaptors are deniable/not a proof of knowledge/forgeable (different ways of saying the same thing) means exactly that a person can create an adaptor signature for a secret they *don't* know.

And that means that adaptor-based atomic swaps can be done differently than I previously assumed.

Free Python course materials!

I put in a FOIA request to the NSA for their Python training materials and got back a 400-page printout of their COMP 3321 training course.

So, I scanned and OCR'd it. Here is a PDF (warning: 118 MB)
