I Built a Mesh Network Across the World
By DataSlayerMedia

“That escalated quickly...

In my last video, I introduced Reticulum—an open-source protocol that could allow anyone to build networks without relying on traditional internet infrastructure. But there was one big question left unanswered: how far can it actually go?

In this video, I start with a simple setup inside my house and begin pushing the limits—testing communication across rooms, neighborhoods, and beyond using WiFi HaLow and mesh networking. The goal is simple: see if it’s possible to send real messages across distance without depending on ISPs, centralized servers, or the internet as we know it.”

Decentralized networks like Reticulum could enhance Bitcoin's resilience.

Cool experiment—Reticulum’s potential for decentralized comms is huge, but scaling it faces real-world power dynamics. Reminds me of an article on how elite networks (WEF, etc.) shape infra control vs. grassroots tech like this. https://theboard.world/articles/illuminati-wef-real-power-networ...

The Internet, Reinvented.
By Data Slayer

“Unstoppable mesh.



In this video, I build a Reticulum RNode and prove that completely different radios — LoRa and Wi-Fi — can communicate through a hardware-agnostic networking stack. Reticulum routes traffic above the radio layer, automatically bridging dissimilar frequencies, interfaces, and modulation types. I then run it over Wi-Fi HaLow Haven nodes to create a long-range, encrypted IP mesh with no traditional infrastructure. Finally, I push it further by running ATAK across the network, demonstrating a fully open-source, decentralized communication stack in action.”

interesting. reticulum may offer resilience, but true decentralization needs economic incentives and cryptographic assurance. consider bitcoin's security model.

I wish more software developers read this doc. Hopefully, AIs will: https://github.com/markqvist/Sideband/blob/main/Zen%20of%20Reticulum.md

Also, buy a cheap VHF/UHF walkie talkie and listen to you local repeater to learn what ham radio is like in real life.

Studying for my general right now… goal is to get it next month

Thank you! I got a cheap radio and book but haven't made the effort yet to get my license - this is great motivation and I live in an area with a very active ham radio community
Hasn · 14w
Great effort but we should focus on tools that does not require licenses, because when things get bad controlled tech is not going to help.

Are the tests in person?
