CONFIRMED: This will be the final TABConf.

After many incredible years, we have decided that this year's TABConf 8, happening Oct 12-15, 2026 in Atlanta, GA, will be the last one.

TAB started in 2016, back when there weren't many Bitcoin meetup groups. In 2018, we started the conference because the meetup had grown insanely large. From the beginning, TABConf was arguably technical, and over time it became even more technical, partly because that is what interested us, and partly because there was a real gap after Scaling Bitcoin faded away.

Today, that gap is much smaller. There are now many great technical Bitcoin events and communities: regional bitcoin++ events, Adopting Bitcoin, OP_NEXT, Presidio, MIT Bitcoin Expo, the Bitcoin Conference open source stage, BitDevs groups, and many more.

That is a good thing!

TABConf was never built as a business. It has always been community service: volunteer run, historically carried by a small core group of a few people, with a much larger group of volunteers making it possible every year.

The goal was always simple: keep it technical. Avoid price action, charts, "wen moon" talks, and hype.

I have always said TABConf is not the place to come learn why Bitcoin is great. It is the place where, once you know Bitcoin is great, you come to learn what you can do next.

It has always been a builders and doers conference.

I still believe true sovereignty requires a minimum level of technical competence. I think this remains one of the most underrated ideas in the space. It is often dismissed by people who believe the entire burden is on developers and designers to abstract everything away. But in reality, the healthy place is somewhere in the middle. Taking responsibility for your own digital money is still a new idea for many people.

No one is too old, too new, or too "non technical" to learn how Bitcoin works. But that knowledge requires practice, repetition, and maintenance.

TABConf tried to create that space. It was a space that wasn't afraid to experiment with interactive puzzles and bizarre/funny formats that involved many people in the room instead of just generic panels and talks.

I also want to give special thanks to Brandon, who has been doing TAB with me for 10 years. He stuck it out with me through all of it, and TABConf would not have been what it was without him.

Brandon was also the one who had the idea to use GitHub and go fully open source with how the conference is organized in public. I really think that kind of open programming and communication made TABConf unique, and it is also something others have experimented with since.

There are many others I want to thank too: Stephen, Brianna, the Socratic BitDevs Village hosts, the Next Generation Village hosts, our speakers, volunteers, attendees, sponsors, and everyone who contributed.

I am not trying to play favorites..... but the full list is probably hundreds of people deep. Thank you to everyone who helped make each TABConf an amazing experience.

Over the years, I have heard from so many people about friendships, jobs, projects, companies, general opportunities that came from TABConf. There's even people who have met their spouses! It is hard to measure the impact, but the vibes have always been high, and I believe we all made serious good use of our time at TAB events.

That means more to me than I can properly express.

Let's send it off the right way!

I hope you will consider coming to TABConf this year and helping us make the final one a blast. We are accepting sponsorships, selling tickets, and, as always, it will be in Atlanta, GA.

All info should be available on the main TABConf website.

Thank you to everyone who came to @TABConf 8 - Oct 12-15, 2026 ATL 7 and made it wonderful this year!

4 days of: cordial debates, technical workshops, talks and panels, interactivities, meshtastic devices, hardware hacking, the CTB puzzle. So much fun.

7 Things I would like to share from TABConf 7.

1. Huge sponsor love for enabling our grants and supporting the conf: lclhostresearch @HRF, SetDevBTC, BitcoinTutorials @Spiral FulgurVentures unchained jintekc @Fedi @andurobtc CleanSpark_Inc lightspark, DCD

2. So many new faces inspired to build on Bitcoin. Special love to the Brazilian crew who also hit the Rust Bitcoin Summit at @Bitcoin Park . Shout to @Lucas Ferreira 🇧🇷⚡️ on the great work with vintenum and @Satsconf (Nov 7).

3. Thanks for personalized education and attention from so many talented folks especially some core contributors like @Murch and achow101. And those encouraging technical education with a carrot 🥕 via CTB donors, you rock!: jintekc fedibtc @Bugle.News #40HPW🎧 Anchor Watch, TaprootWizards.

4. Adhoc and satellite events and activities were a blast: @Stephen DeLorme @ATL BitLab 👷🧑‍🏭💃 @Shelly Legit @isabelfoxenduke Afterparties 🥳 @D++ Mario Kart Double Sats 🚗 @niftynei() 🇺🇸💸🧡 Bitcoin at work-shop. The chess tournament crew: jondomedia @Bitcoin Party KC bitcoinburnbabe. ♟️

5. Massive thanks to @Walton 🕶️ @CryptoDoctor @Brianna HD Brandon @ExFrog @Alex Lewin and all volunteers for setup and breakdown in record time.
lclhostresearch crushed the Socratic BitDevs village as always. Hardcore trivia was amazing and super efficient.

6. Debate panels drew big crowds again. Year 2 of the format and going strong. Thanks Paul Sztorc and @Hunter ₿eaṩt for setting context and involving the audience.

7. The warnet hosted by Zipkin was awesome. Big shout to chaincode for supporting it the last 2 years. Hacking LN ⚡️⚠️ nodes was a blast. Our evening WoT with @Christopher Allen 🔐workshop sparked ideas for recurring web of trust events at TAB.

I cannot wait to see you all next year for TABConf 8. Tickets are on sale now at early prices. Support the conference and grab yours today! Save the date: TABConf 8 is Oct 12-15, 2026. Mark your calendars! 🗓️

> I also think that without filters, monetary txs can displace jpgs, which doesn't look like it is the case in this graph.

I would generally agree. The minimum demand/value of a monetary tx/usecase would need to be higher than the highest demand/value of a "jpeg" tx in order to have zero spam/jpegs in the next block. This isn't intuitively represented I suppose for the graph (based on the x axis as you point out), but it's how I intended this to be interpreted.

Yes we can run epidemiological simulations and Laurent a big defender of filtering has just proven that it doesn't work https://twitter.com/LaurentMT/status/1973416866212180089

@calle, I'm curious if you agree with the chart.

~85% is generous imo. You could push it more aggressively to 95–99%, but I figured 85% would serve as a starting point, since I didn't want the whole discussion to revolve around the arbitrary majority needed for a filter to be noticed.

I'm wearing the @tunestr hoodie today in a coffee shop, a girl there knows my name is mike. She asks me.. "Are you Mike from tunestr". Holy crap.. small world, and too many Mikes.

Can we objectively measure (point in time) relay filter effectiveness?
We can by looking at the friction a Tx/usecase faces getting into a block.

Filtering on datacarrier (preventing OP_RETURNs from exceeding 83 bytes) lives in the [pink box]
Sharing this as a discussion point.

anything outside of the pink box is uncontroversial, so you need to justify why something should be included

nice, the X axis is important here. It's where the "filters work vs dont work" discussion is breaking down.

I wonder of min relay fee would be a good model to analyze. Most nodes filtered less than 1sat/vbyte, but from a bystander's view when fees dropped below that, it didn't seem like there was any trouble filling blocks with sub 1/sat/vbyte. How would you measure the friction?

As the older generation passes on it will go away. I'm just on the verge between Gen X and millennial. I've never had a paid TV service in my house, and I can't remember the last time I watched broadcast TV, even at a friend's house, because they don't either.
