in austin august 21st-22nd
(weekend before bitblockboom dallas)

bring your pajamas

(there’s a hackathon)

our lovely event sponsors

key dates

see below for exact agenda.

other fun around the event is the 21st/22nd, but there’s some other nearby bitcoin stuff

what is this “hackathon” you speak of

it is the friends you make on the journey. we will have a 24 hour hackathon starting after the workshops (please sleep tho) for plebs to build and showcase innovative ideas for the bitcoin ecosystem. don’t have any ideas or friends? the workshops on saturday will surely inspire.

there will be prizes. a bevy of them (subject to change till the event starts).

1st$5000fancy cowboy boots + limitd edition shirts
2nd$1000limited edition shirts
3rd$500limited edition shirts
New Layer 2s$250
Self Sovereign$250

basic rules

no cheating allowed – while it’s OK if your submission is part of a larger project or ecosystem (e.g., you are a c-lightning Dev and you build something in c-lightning), the point is to try out new things and explore. there’s no firm rule here – we’ll know cheating when we see it, and disqualify at our discretion. when in doubt, ask an organizer if your project is in the spirit of the event.

we love teams; but we also love to see lots of projects. to strike the right balance, teams may have up to 3 attendees.

to make the event more inclusive, you can also have a ‘remote only’ +1 teammate, just let us know in advance who they are. in the spirit of getting real remote participants, we encourage remotes to be e.g. 2 hours+ away from austin (if you see them during the event in person it’s a disqualifier). interested in being a remote hacker? either ask your friends attending or sign up to share your info with teams.

we’ll adjust these rules as the event draws near; ask any clarifying questions in the telegram.

why are you charging money? not cool.

organizing events is hard. charging admission serves a few purposes: 1) we want to ensure that our limited space goes to people who want to be there, no flakes; 2) we’re going to ensure there’s good food available throughout the event. we’re running the event as not-for-profit, any excess funds will go to supporting our non-profit partner or future events. if paying for a ticket is an obstacle for your attendance, please let us know by filling out this form and we’ll work something out.

the (not) secret agenda

we may adjust this as we near the event…

Hackathon Project Ideas

List of project ideas

learn a little rust and get set up as Sapio is in Rust – a little bit / env setup will go a long way for following along!


if you have an editor you like for rust already, ignore. in my experience, vscode is the easiest out of the box quick setup.


Speaking of.. Sapio setup is here and GUI is here

Still doing a lot of changes before the workshop, but it’s usable now. Make sure your environment is set up before you come so you have no problem using it.

get bitcoind setup

Have bitcoin core compiled locally and ready to run in regtest you don’t want build issues slowing you down, nor (if you want mainnet) do you want to have to sync on wifi with 100 other people.


LSATs, or Lightning Service Authentication Tokens, are a new way to do pseudonymous authentication using the lightning network, leveraging the native 402: Payment required http error code, and macaroons.
