In the spirit of "building in the open" here's a fuzzy video show 3 users entering into a competition, creating an aggregate signature via musig2 and broadcasting the funding transaction of a dlctix contract after the coordinator's wallet successfully signs it. Next will be getting the payout out functionality working/hooked up along with a nostr public chat group. Once the features have all landed, and there's been a bit of code clean up, all the code will be open sourced https://streamable.com/c91tsg Technologies used so far: - bdk-wallet in the browser and server:

The bitcoin regtest environment is being manager and run via doppler locally as well (creating the bitcoin node, esplora instance and a few connected lightning nodes):

I’ve decided I’m going to open source this project I’ve been grinding on that is a coordinator for a dlctix competition around weather predictions. Basically users will create entries for a few points of predictions across a number of cities and compete against others in the competition for coin (flow feels similar to daily fantasy sports). The coordinator can be fully untrusted and is non-custodial of users funds. Payouts can be on-chain or lightning and entry fees are paid in lightning. The competitions is a dlc contract on chain and the competition outcome is determine by an oracle that attests to who won. Code is still actively being worked on and not really just yet to release it, but keep an eye out, more to come soon 👀

Been cooking this weekend 👀

DLC related tech is the most slept on in bitcoin dev IMO, but it has the potential to make some very interesting products. I think people dismiss it due to it behind hard to build and scale. It also has to be tailored for whatever you use-case is, rarely vanilla DLCs get you all the way there

Big release for Doppler! v0.4.0 An Esplora instance can be attached to any Bitcoind setup in a simulation doppler file. Take a peak at the example Doppler setup 👀 github.com/tee8z/doppler/… github.com/tee8z/doppler/… It turned out to be a challenge, but I'm excited to start using it!

For anyone that tried to use Doppler’s

release binaries in the past on an Apple computer, I finally got around to fixing the build and the latest release will work on a Mac now, cheers 🍻

With all the soft fork talk

Taking a much needed break up in Maine with my wife, a lovely place. I could definitely see myself moving here

Get ready for some simulation magic, preview of new look for Doppler 👀

Build pipelines are hard, a lesson that never ends

I’m starting to realize with window.nostr and the ability to display or pay a lightning invoice, that gives a developer a lot of cryptographic primitives that makes creating a dlctix client in the browser possible, I’m kind excited to see what I can make with them

Always a pleasant surprise when you get a PR from an anon into a library you created and forgot about

Does anyone know of a good open source example on how to implement nostr login, with extensions or with having the user create their own keys in the browser ( having the key creation offloaded to rust wasm)?

Always satisfying getting a side project to “working”, but then the real beast of deploying shows up to ruin the fun

Youth brings change and energy, if you find a problem to solve young nothing wrong with going all in

Highly recommend making a trip to New Hampshire white mountains if you ever get the chance, they are quite the sight and an incredible place to backpack, picture from my most recent trek there

“Split a commit, make your code reviews life easier, it can’t be that hard…” absolutely rugged myself, thankfully “git reset —hard” exists and learned to push it remotely before trying to get fancy with git a long time ago

Headed to BBB, ready to share some sweet lightning simulations

Incase anyone wants to see a chain of force closures automatically happen due to inflight htlcs and a peer going offline for too long, got a Doppler simulation for you 👀: https://github.com/tee8z/doppler/blob/master/doppler_files/force_close/README.md
