Tired of free learning still being trapped behind paywalls or bureaucratic barriers?

For the past 2 years, I've been working on a dream: Arborito. An open-source, free, and decentralized platform to learn anything through interactive lesson maps, with no ads, no subscriptions, and no reliance on closed platforms.

Every screen, flow, button, and concept in the app was designed and redesigned a thousand times until I got the exact experience I envisioned. Since I'm not a senior developer, I used LLMs as an assistant to help translate my ideas and architecture into code.

Today, Arborito arrives in its Alpha version. This means it is a fully usable and functional version, but since it's in its early stages, it's normal to run into bugs, unpolished details, or areas for improvement. This is a 100% community-driven, open-source project (GPL v3): the goal is for this Alpha to serve as a foundation so the community can test it, report bugs, optimize the code, and grow this tool together.

🌐 Try it on the web: https://arborito.org 💻

Code & Installation: https://github.com/treesys-org/arborito

My vision isn't just to build an app, but to start a movement. The long-term goal is to expand this into physical learning spaces around the world, proving that knowledge is a right, not a privilege.

If you share this vision and want to join, whether by testing the app, reporting bugs, translating, creating courses, or contributing to the repository, you are more than welcome!

Here's a quick video showing how the app works: https://www.youtube.com/watch?v=NsM9pEPSzcc

Looking forward to your thoughts and feedback!

Some searches suggest https://mostr.pub/ , but mostr can only do the opposite direction: follow a mastodon account in nostr

How can I follow someone on primal.net , in mastodon?

For years, the biggest knock on Nostr's messaging wasn't censorship resistance, it was privacy. Anyone who dug into how direct messages actually worked on the protocol found some uncomfortable gaps. That's changing fast.

The problem with the old system

Nostr's original DM standard, NIP-04, was functional but leaky. It encrypted message content, but metadata who was talking to whom, and when was still exposed. NIP-17 improved on this with a "gift-wrapping" approach that hid more of that metadata, but it still fell short on two fronts that matter a lot for real private messaging: forward secrecy and post-compromise security. In plain terms, if a key ever got compromised, past and future conversations could be at risk too.

Enter NIP-ee

A new specification, NIP-ee, brings MLS (Messaging Layer Security) to Nostr. If that name sounds familiar, it should, MLS is the same class of protocol underpinning Signal's famous encryption. Adapting it for Nostr means:

Forward secrecy : compromising a key today doesn't unlock yesterday's messages

Post-compromise security : the system can heal itself after a compromise, protecting future messages too
Efficient group messaging : MLS is built to scale to large encrypted groups, not just 1:1 chats

The core idea, straight from the people building it: without proper end-to-end encryption, Nostr can't seriously compete as a protocol for secure messaging. NIP-ee is the attempt to close that gap for good.

Why this actually matters

This isn't just a technical footnote. It's a narrative shift. Nostr has always led with censorship resistance, no single company or government can shut it down. But "censorship-resistant" and "private" are not the same thing, and Nostr has historically been stronger on the former than the latter.

With MLS-grade encryption landing, Nostr starts to make a case it couldn't credibly make before: that it can be censorship-resistant and genuinely private, without trusting a centralized server to keep your conversations safe. Decentralized servers ("relays") pass encrypted data along, they can't read it, and no central actor can flip a switch to stop people from talking.

What it means for you

You don't need to understand the cryptography to benefit from it. As MLS support rolls out across Nostr clients, your DMs get quietly stronge, less metadata exposed, more resilience if something ever goes wrong with a key. It's the kind of upgrade that happens under the hood but changes what you can trust the network to do.

Nostr's story has always been "own your identity, own your content, own your audience." Now it's adding: own your conversations too.

“The problem wasn’t raising the money,” he told me from a displacement camp in Gaza. “The problem started when we had to rely on someone else to receive it for us.”

...

The weakness Sami’s case exposes is not unique. Crowdfunding platforms can raise money for families facing war, disaster or repression within hours but getting it safely to the intended recipient can be far more complicated.

...

Bitcoin allows funds to move across borders without a platform holding them or a beneficiary passing them on. Risks around wallet security, access and exchange rates remain.

For Mary Kate, that control has significance beyond the movement of money.

“We can’t take your account from you. We can’t shut down your campaign. We can’t take your money,” she said. “For people dealing with trauma and a lack of control over their lives, that can be a huge moment of empowerment.”

NONO Social is officially live.

It’s the beginning of a unified ecosystem built around one idea:

Privacy. Ownership. Freedom.

NONO Social is powered by Nostr, meaning there are no platform-owned accounts and no central database controlling your identity. Your keys are your identity.

We’ve also completely redesigned the experience with a new premium look that will become the design language across the entire NONO ecosystem.

Over the coming updates you’ll see the same visual identity rolled out across:

• NONO Social
• NONO Wallet
• NONO Explorer
• Future NONO applications

One ecosystem.

One brand.

Built on open protocols.

Built for people who believe they should own their identity, their money, and their communication.

We’re just getting started.

Github is on homepage and opensource.
