find those nodes that support onion message forwarding 👀

Ngl something that makes me as nervous about the mempool accelerators affect on the accuracy of fee estimation from a regular bitcoin core node are the plans of a futures market for block space. This will distort the accuracy of what it cost to get a transaction mined within a given range of blocks as these futures pricing and timing will most likely be private between a large miner and a service provider. Making it quite difficult for applications/protocols that require get a block mined within a given range to actually accomplish this goal. Especially if something in that futures market acts is a surprising way (flood of futures transactions all coming due at the same time pushing out what would normally get included just looking at one’s own mempool estimation). Something to think about when building new or expanding existing protocols, you may not be able to get your transaction mined within a given range just based on the data feed from the “spot market” (price from the mempool), you’ll need some way to know what future contracts are settling at a given price to see what is truly required.

New weird software just dropped, keysend messages around to all your lightning node buddies:

I added the ability to easily Doppler to a box running in the cloud! Should make it much easier to build against a regtest or signet cluster of nodes and share with a team:

Example of what it looks like when deployed

Have a test site running on mutinynet, no nostr chat/alerting yet as I focused my time on making the buy-in and pay-out screens plus getting the deployment working. Nostr chat and alerts up next. I open sourced the coordinator code this weekend as well for those curious:

Build more weird software, make the odd tool nobody but you might use, enjoy the craft of making something

Finding the sweet spot for highest success rate with lightning payments 👀

More progress made this weekend, finally have payouts working. Next step is adding in a nostr chat and emitted notifications from the coordinator to users about a competition they are in. A test site on a signet coming soon™️ View quoted note →

I think dlctix sweet spot for a viable product will be person to person future contracts used as way to hedge risk in people’s lives and businesses, this is something the traditional financial system doesn’t really support in any meaningful way. Future contracts are really a product used by much larger institutions to hedge risk, which the traditional financial system optimized for, but these sorts of products could be useful if package in a clean UX.

@npub1ew4n...6qlf alright let’s see if this wallet of yours works tapbc1qqqszqspqqzzpprh6m04jcxvqh3hh9q3hnlf4x7ns6qhy73sgww8hg8yug25smj0qcss9xk6yuc0z9tmwgvfpsg6c5vukehqahgt42tdu85nxh585nmvdagvpqssylsm6277gyn3t9c4t6qntwluclu82chmqgqzamxegzdsf0mlmnzlpgqkgrpww4hxjan9wfek2unsvvaz7tm4de5hvetjwdjjumrfva58gmnfdenjuenfdeskucm98gcnqvpj8y8kgdze

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
