Best way to learn transactions, mining, wallets and consensus is by playing a bitcoin game!

Multi-vendor multisig is the way to go after the exchange hacks, supply chain attacks and entropy bugs.

Pacman from DIYbitcoin is showing us how to keep our bitcoin safe at the Dev Day hosted by Calvin Kim in Seoul, Korea.

Nice to see Code Orange Tshirt give-away at Bitdevs Zaria meetup. Thanks to Husteemah and the team as well as

for building fun bitcoiner communities.

We ran a Bitcoin + Agentic Engineering workshop where bitcoiners vibe coded real projects on the call.

No slides. Just vibe coded bitcoin websites.

Meeting notes and a video recording here: https://codeorange.dev/session-notes/2026-10-21-agentic-engineering

Join us tonight to discuss how bitcoin + vibe coding allow bitcoiners to increase their productivity.

Would you want everyone you pay to know how much bitcoin you own?

This was one of the questions we discussed in our latest privacy workshop - alongside a live Lightning payment, plenty of good questions, and a few rabbit holes.

Our next call is tomorrow. See you there: https://discord.com/invite/WycFTWcMT?event=1520663887471710248

How do you self-custody bitcoin without anyone knowing you have it?

Bitcoin as an asset might fail if we don't have private payments.

Payjoin makes it much harder for chain analysts to track your payments. Join our Privacy Track starting on 6th October on Discord: https://discord.gg/6XPJ96sCY4?event=1550726832419250216

We are open-sourcing our Bitcoin Basics slides.

5 sessions: why Bitcoin exists, how it works, wallets and keys, Lightning, security, nodes and seed phrases.

Use them at your meetup: https://github.com/code-orange-dev/bitcoin-basics-slides created by The Quiet Satoshi

Chain-analysis assumes all inputs in a transaction belong to one sender.

Payjoin breaks that, because the receiver adds an input too. The amount is hidden and the heuristics become unreliable.

Our Privacy Track starts next week.
