The first live show at Pubkey last night was a blast! Thanks to everyone who came out, especially in the middle of our first snowstorm of the year.
Most of the examples of data embedded in the blockchain are catalogued here: https://cirosantilli.com/cool-data-embedded-in-the-bitcoin-blockchain
This 2018 paper goes over different techniques to embed arbitrary data, including the Satoshi uploader I'd mentioned:

@BitMEX
did an amazing article on the OP_RETURN wars that covers Counterparty: https://blog.bitmex.com/dapps-or-only-bitcoin-transactions-the-2014-debate/
The PSBT dutch auction stuff that @orenyomtov
is working on is here https://openordex.org
The case of the Slovakian politician sending financial transactions that were secretly coded messages is here:

...and I think that's all? DM me if you have any questions and see you next time!

My first guess is that relays will start filtering events based on the kind tag (in fact that functionality already exists for some relays for kind 1984).
From a comment on an HN article about the causes of the decine of UseNet:
"These days we're used to being overrun by everyone who can use a point-and-drool interface on their phone to look at Facebook, but back in September 1992 it was a real shock to the system when usenet was suddenly gatewayed onto AOL, I can tell you. Previously usenet more or less got along because the users were university staff and students (who could be held accountable to some extent) and computer industry folks. Thereafter, well, a lot of the worse aspects of 4chan and Reddit were pioneered on usenet. (Want to know why folks hero-worshipped Larry Wall before he wrote Perl? Because he wrote this thing called rn(1). Which had killfiles.) "
...we're gonna need nostr killfiles Soon. https://en.wikipedia.org/wiki/Kill_file
How do I @arbedout to tell him I'm going to fuck him up during this Ordinal chat tonight. Do I have to vomit his entire pubkey here?

Literally you can't figure out how to @ people, I ain't scurred
gm, ETHDenver has approximately 60% the number of attendees as the Midwest FurFest, America's largest furry convention
gm, Gary Gensler is an ex-Goldman Sachs investment banker in an appointed-not-elected position, this guy isn't your friend just because he's making shitcoiners miserable.
better to let all these bad ideas fail on their own (lack of) merits instead of cheering that they're being regulated out of existence
The PSBT auction stuff is undeniably cool. I hope it gets more traction / use cases. Maybe the POWSWAP hashrate derivatives Jeremy Rubin was working on...?
Moving on from UseNet to the death of Gopher, comparing this article:
"Where Have all the Gophers Gone? Why the Web beat Gopher in the Battle for Protocol Mind Share" https://ils.unc.edu/callee/gopherpaper.htm
...with an interview with Mark McCahill, lead Gopher dev:
https://conservancy.umn.edu/bitstream/handle/11299/107471/oh328mmc.pdf
TL,DR:
Historian: This protocol failed due to complex technological and sociological problems
Lead Dev: "What killed the protocol off was when people stopped using Gopher clients specifically and started using Mosaic" 🤔
The combo of:
a) this Politico oral history with Biden admin officials marking the one year anniversary of the war in Ukraine - in which sanctions against Russia are described in terms of 'shock-and-awe' and collective punishment, with Treasury officials imagining themselves as warfighters deterring enemy behavior and blithely ignoring collateral damage
https://www.politico.com/news/magazine/2023/02/24/russia-ukraine-war-oral-history-00083757
and
b) this Bloomberg article published on the same day, quietly admitting that sanctions proponents have given up on them having any impact on Russia's behavior
has convinced me we're in the final stage of the decline of the dollar system, in a "where are we going and why are we in this handbasket?" kind of way.
Don't get too excited. The IRR has been declining for literally my entire life. It's just an endless free-fall with no silver lining.
Opt out.

CBDC strategy docs, but make it 30 years ago

I think it's great that this mining pool came back from the dead right after that first non-standard ordinals transaction was mined and people started getting shouty. Definitely not an existing player spoofing the OP_RETURN in the coinbase transaction to avoid criticism!

Thanks! I'm trying to make sure that it is.
If you'd like an introductory text on networking that's accessible and also practical, I'd recommend How the Internet Really Works: An Illustrated Guide to protocols, privacy, censorship, and governance from Article 19

Sharing this to help motivate me to get finish Chapter 7 and what I anticipate to be a loooong slog through Chapter 8:

Excited to announce Based, a new programming paradigm for aspiring blockchain developers!
How it works:
* You send me a DM on Nostr
* I explain to you that you don't need a blockchain
* You call me a poisonous feminine hygiene product, or a toxic maxipad, or whatever, idk
* Five years later you realize you're wasting your life and rebrand as being 'Pro Bitcoin', just in time to buy the top of the next cycle.
Welcome to the future. It's Based.

awesome, thanks for the pointer, didn't know that nip existed!
gm, thinking of ways a client can bootstrap a list of relays and test that they're minimally trustworthy in some way. maybe we end up defaulting to nip-05 relay recommendations - if that happens, would providers injecting their own relays into a user's records be helpful or viewed as an attack vector?
maybe a canary bot that tries to send restricted samizdata - 3D PDW files, politcally sensitive speech, financial transactions to blacklisted addresses - through a list of relays and testing end-to-end delivery would be useful?
