Laszlo's pizzas by Ciro Santilli 40 Updated 2025-07-16
On May 19, 2020, Lazlo announced on the Bitcoin Forum at: bitcointalk.org/index.php?topic=137.msg1195
I'll pay 10,000 Bitcoins for a couple of pizzas.. like maybe 2 large ones so I have some left over for the next day. I like having left over pizza to nibble on later. You can make the pizza yourself and bring it to my house or order it for me from a delivery place, but what I'm aiming for is getting food delivered in exchange for bitcoins where I don't have to order or prepare it myself, kind of like ordering a 'breakfast platter' at a hotel or something, they just bring you something to eat and you're happy!
I like things like onions, peppers, sausage, mushrooms, tomatoes, pepperoni, etc.. just standard stuff no weird fish topping or anything like that. I also like regular cheese pizzas which may be cheaper to prepare or otherwise acquire.
If you're interested please let me know and we can work out a deal.
Ciro Santilli remembers his father always telling him how when Ciro was small, he would try to grasp the value of money by converting it into how many pizzas he could buy. Well, at least he was not alone.
User bitcoin2paysafe then asks the fundamental practical question:
In which country do you live?
and Lazslo replies:
Jacksonville, Florida
zip code 32224
United States
User ender_x then points out afterward:
10,000... Thats quite a bit.. you could sell those on www.bitcoinmarket.com/ for $41 USD right now..
so it is a slightly bad deal even then!
Three days later Lazlo's asks again on the thread:
So nobody wants to buy me pizza? Is the bitcoin amount I'm offering too low?
and one day later he confirms that the sale was made without naming the buyer:
I just want to report that I successfully traded 10,000 bitcoins for pizza
Thanks jercos!
where "jercos" is presumably the Bitcoin Forum username of the buyer. en.bitcoin.it/wiki/Jercos gives his identity as Jeremy Sturdivant.
www.thesun.co.uk/news/15049566/other-bitcoin-pizza-jeremy-sturdivant-fortune-hanyecz/ mentions Jeremy sold too early however:
The cryptocash disappeared when Sturdivant used it to "cover expenses" while travelling the US with his girlfriend.

Laszlo's secondary pizza event
. Source. web.archive.org/web/20210217220810/http://heliacal.net/~solar/bitcoin/lightning-pizza/ documents another pizza event, as we have different pizza boxes from the most widely known one: web.archive.org/web/20211219130004/http://heliacal.net/~solar/bitcoin/pizza/ Only image thumbs are archived however. web.archive.org/web/20211016070745/https://www.thesun.co.uk/news/15049566/other-bitcoin-pizza-jeremy-sturdivant-fortune-hanyecz/ however shows a large version that The Sun got their hands on before the takedown.
heliacal.net is presumably his personal website? But is was down as of 2023. But we have Wayback Machine archives of course :-) Latest working one of that page 2021: web.archive.org/web/20211219130004/http://heliacal.net/~solar/bitcoin/pizza/ And some other stalking:
Laszlo is truly, literally, the nerd who got very very very lucky!!!
On June 12, 2010 Laszlo re-offers:
This is an open offer by the way.. I will trade 10,000 BTC for 2 of these pizzas any time as long as I have the funds (I usually have plenty). If anyone is interested please let me know. The exchange is favorable for anyone who does it because the 2 pizzas are only about 25 dollars total, maybe 30 if you give the guy a nice tip. If you get me the upgraded extra large ones or something, I can throw in some more bitcoins, just let me know and we'll work something out.
My 1 year old daughter really enjoys pizza too! She just smears it all over her face if you give her a whole slice, but she does eventually manage to get most of it in her mouth (minus a few loose toppings of course).
and on August 4 user MoonShadow takes him up:
An open offer, you say? It's been a while since you had some pizza. Feeling a craving, Laszlo?
but finally Laszlo withdrawls the offer:
Well I didn't expect this to be so popular but I can't really afford to keep doing it since I can't generate thousands of coins a day anymore. Thanks to everyone who bought me pizza already but I'm kind of holding off on doing any more of these for now.
so we understand that the sales happened multiple times!!! Also, we understand that he was probably a miner.
TODO list all of the potential sales.

Isomer by Ciro Santilli 40 Updated 2025-07-16
Isomers were quite confusing for early chemists, before atomic theory was widely accepted, and people where thinking mostly in terms of proportions of equations, related: Section "Isomers suggest that atoms exist".
Alpha decay by Ciro Santilli 40 Updated 2025-07-16
Most of the helium in the Earth's atmosphere comes from alpha decay, since helium is lighter than air and naturally escapes out out of the atmosphere.
Wiki mentions that alpha decay is well modelled as a quantum tunnelling event, see also Geiger-Nuttall law.
As a result of that law, alpha particles have relatively little energy variation around 5 MeV or a speed of about 5% of the speed of light for any element, because the energy is inversely exponentially proportional to half-life. This is because:
  • if the energy is much larger, decay is very fast and we don't have time to study the isotope
  • if the energy is much smaller, decay is very rare and we don't have enough events to observe at all
Bitcoin IRC channel by Ciro Santilli 40 Updated 2025-07-16
A lot of important development discussion happened in those channels: en.bitcoin.it/wiki/IRC_channels
At www.reddit.com/r/Bitcoin/comments/5pvp6m/is_there_a_log_for_the_bitcoin_irc_channel/ "Is there a log for the bitcoin IRC channel?" Luke Dashjr comments:
No, it is meant to be private without logging allowed.
User "midmagic" (TODO identify) then comments:
The #bitcoin channel on Freenode is "officially unlogged." That means we officially don't publish the logs anywhere, and if we find that logs are published somewhere, we ask that they be taken down
Some IRC logs were dumped into the Bitcoin blockchain at: IRC log dumps where they cannot be deleted.

2023-11-17 bitcointalk.org/index.php?topic=5478677.0 "I Bought vistomail.com. Now What?" Restricted topic, but Google caught it: archive.ph/wip/dDxqi The message:
I am dedicating the next few months, and perhaps even years, to researching Satoshi Nakamoto and the intricacies of blockchain technology. About four weeks ago, I came across vistomail.com for sale on afternic.com and decided to purchase it. I added vistomail.com to my proton.me account and configured it to catch all emails. As a result, numerous emails started flowing in. Subsequently, I connected satoshi@vistomail.com and discovered significant information that I am excited to share with you in the coming months.
To be clear, I want to emphasize that I am not Satoshi Nakamoto. My interest lies in understanding the future plans for Bitcoin and its impact on the world. I invite you to join me on this journey, contributing your knowledge to the collective understanding. I believe there is a possibility of uncovering the ultimate treasure, and I am eager to share it with all of you.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
