People talking about magic.

Arriving tomorrow afternoon. nostr:nprofile1qqsw7hey8kjyfqw33dq4eza03xqps94wh0rvaqhr30pzhvjnr83mljspzamhxue69uhhyetvv9ujuune0f5h5atz9e3k7mgpp4mhxue69uhkummn9ekx7mqc9ncs7 could give you some tips.

The best collaborations are when everyone can be part of the whole process, has a say, and chips in to the parts they are really good at.

I'm excited for the dev/hack/day at BTC Prague next week. I'll present findings from the interviews with activists we did at the Oslo Freedom Forum. They have serious problems bitcoin can help with, but the majority is not using it. https://btcprague.com/dev-hack-day/

Cool to see the global nature of hackathons... also would love to see more europeans.

Well, I am certainly going to work out. Gotta stay healthy.

Really enjoying the nostr:nprofile1qyxhwumn8ghj7cnjvghxjme0qyt8wumn8ghj7etyv4hzumn0wd68ytnvv9hxgtcqyzxznvep6reuvy6r3qh2f93raprhz6gv6ptxus9epuywt56rx642qa309x5 accessibility calls today. Jason has a wealth of knowledge and the workshops get super hands-on.

This research confirms my personal opinions, so I think it's great. No seriously, it's an interesting read.

I asked Claude to do a usability review of nosta.me. It spent 15 minutes to successfully set up a profile and put together a nice usability report.

Prompt and report are included in a doc under the video. If you're working on a web app, I recommend doing this to get a good baseline review. Just let it run during your next coffee break.

Also, here's the account it set up: https://nosta.me/ebd37ae82a97cc58196ba8e1d5bdb3c45547ce5fa1af9e181a4bec8a8f7db7ba

And speaking of hackathons, you should join the Bitcoin Designathon. It starts this Sunday. https://event.bitcoin.design/

Spent the weekend with my son on the Runway 48-hour hackathon and we came up with this goofy short-film. Was a great chance to tinker with all the latest AI video/image/sound tools. Tons of limitations still, but also very powerful (and fun).

Have you tried Saving Satoshi to learn bitcoin tech & coding? Would love to hear what you think. https://savingsatoshi.com

New Ark Simple explainer & FAQ

https://docs.arklabs.xyz/

Bitcoin's blockchain offers strong security guarantees at the tradeoff of limited transaction throughput, high fees, and settlement delays, restricting its practical use for various applications requiring greater scalability, lower costs, or faster settlement.

Ark addresses these limitations primarily through a novel batching technique, aggregating numerous individual Bitcoin transactions into a single onchain Bitcoin commitment—called a Batch Output. This significantly reduces transaction costs per user and greatly enhances scalability.

The protocol mirrors Bitcoin’s familiar UTXO structure using Virtual Transaction Outputs (VTXOs). These offchain abstractions preserve a familiar output ownership model while embedding many claims into a single Batch Output. VTXOs ensure that users retain unilateral control over their funds and enable efficient offchain coordination before final settlement on Bitcoin.
