Why aren't there more communities with their own payment system? Many bottom up initiatives in the past decade but only a few still (barely) survive.

🚆 On the fast train from Brussels to Bordeaux (via Paris) for the first European gathering of community currencies 🔅 Will share the gospel of web3 and ecash in a world still dominated by Postgres databases where a few admins have god access to everyone’s transaction details and balances. Crazy shit. 💩 Criticizing is easy. How can we make it easier for those communities to start from a much more sane digital infrastructure? We need to build bridges with local communities. They are the last mile to onboard citizens to the crypto future we desperately need.

We need a new generation of politicians. Beyond party politics. People that want to genuinely serve their community, with respect for other communities and the commons that we all share. How can we support them? How can we give them the (open source, decentralized, censorship resistant) tools they need to thrive?

We need open source cities. Cities that would operate much like Linux. A small kernel that provides a stable and efficient environment where processes/agents/citizens can easily access common resources.

I went to a local meeting about noise pollution in the city. The elected representative told people that there is no use to file a complain to the police. They should instead directly send them to him. That’s how our institutions collapse. They become useless, people stop using them and start looking for other ways to get things done. How could we create new institutions based on open source principles? Could we create a GitHub Issues equivalent for the city, based on Nostr? A common space where citizens could report issues in an open way?

On the left people want to talk about inequalities. On the right people want to talk about immigration. Two sides of the same coin: a sense of belonging to the same community.

President’s dinner gala ahead of the state of Europe roundtable in Brussels. My yearly reminder that the future won’t be defined by people in suits. Yet, we have to rally some of them to build bridges and make sure they don’t do stupid stuff (e.g. #chatcontrol) I can also recognize the good work of Friends of Europe that is trying hard to create bridges with entrepreneurs, artists and civil society. I respect and support that.

Weekly regen walk

Gm Nivelles. Off we go for the 749th “Tour Sainte Gertrude”. 17km walk around my hometown on the footsteps of Saint Gertrude who established this city back in the 7th century.

I want an OS level highlighter. Let me highlight any text anywhere and keep a record of it. Make it easy to keep a private and public feed and annotate. The ultimate curation tool. Storify 2.0.

Everything is much slower on an iPhone 13 Pro after upgrading to iOS26. Beware. Not sure it’s worth the upgrade.

Thanks for your post. We need more voices to get us out of this idea that people should be able to manage a private key and keep it safe. That’s a non starter. Npubs are like IP addresses. Computer readable addresses that can change over time. Your identity is like a domain name. Human readable that can point to various IP addresses. This web of trust sounds complicated to me to implement. I’d love to suggest a simpler approach: consider a Npub like an active session. That way, private keys (nsec) never leave the device / app that created it (reduces the risk of leaks). Then add those sessions to your profile. As long as you still control one device, you can rotate the npubs. The only change required on the protocol would be to index profile events (kind 0) on each of those npubs instead of just on the author npub (and allow to query them based on any of them). It’s not a full proof solution but it feels already like a big improvement. This would effectively decouple identity and npub. The biggest risk would be one of your devices being compromised. But chances are you could rotate that lost key with another device. Wdyt?

Nothing like sharing a common space to build community. 🔅 That’s why every first Wednesday of the month, the crypto community can now enjoy a free coworking day at the nostr:nprofile1qqs9jj4xw7l4wuv7h68y5fzfelst40wzzcn5ezpr8al04r3hn0jek7sprdmhxw309a3xjarrda5kutnpdehx2cmp9e3h5w358q6rsqg6waehxw309ahx7um5wghx7unpdenk2urfd3kzuer9wcm0c3z3 (just in front of Brussels central station, so easy access from Amsterdam, Paris, London, …) 🎟️ Book your spot: https://luma.com/3dbrjocg We’ll end the day with a happy hour and the regular Crypto Wednesday meetup.
