I’ve been toying with a concept inspired by Apple’s Find My network: Imagine a decentralized, delay-tolerant messaging system where messages hop device-to-device (e.g., via Bluetooth, UWB, Wi-Fi Direct), similar to how “Find My” relays location via nearby iPhones.

Now add a twist: • Senders pay a small fee to send a message. • Relaying devices earn a micro-payment (could be tokens, sats, etc.) for carrying the message one hop further. • End-to-end encrypted, fully decentralized, optionally anonymous.

Basically, a “postal network” built on people’s phones, without needing a traditional internet connection. Works best in areas with patchy or no internet, or under censorship.

Obvious challenges: • Latency and reliability (it’s not real-time). • Abuse/spam prevention. • Power consumption and user opt-in. • Viable incentive structures.

What do you think? Is this viable? Any real-world use cases where this might be actually useful — or is it just a neat academic toy?

I'd like to point you towards Meshtastic [1]. It's off-grid, decentralized text messaging that allows for encryption, and is inexpensive to get into (a basic node is about $30 or less), and don't require a license to operate.

The firmware on these devices is open source (minus proprietary blobs for ESP32 WiFi, etc.) and the community is active. Check the Meshmap [2] to see some nodes that have made their location public in your area.

Meshtastic barely works. There are only a few hundred nodes in Las Vegas and already the main public channels are at high utilization with almost no real end user traffic on it.

I love the project and participate, but people mentioning stuff like this in response to buzzwords irritates me. Like ipfs it is a buzzword-driven curiosity, not a real solution to real problems that anyone has.

Additionally, the meshtastic encryption is a toy. In 2025 when you say encryption you make people think of modern features like replay resistance, perfect forward secrecy, etc. Meshtastic doesn’t do any of this.

IPFS used to be a real solution, we used it as the base layer for the decentralized marketplace OpenBazaar and it worked fairly well for that. I haven’t followed it in a few years though.

IPNS, on the other hand...

I think of IPFS as a cross between HTTP and BitTorrent. Like BitTorrent it can seek a given dataset by some kind of hash, no matter where it's hosted; like HTTP it's more suitable for collections of small files.

In practice, it takes upwards of a whole minute to locate a file it's never seen before, so it's not terribly useful. It's better than nothing, but it's not terribly useful.

It's still cool that someone tried. IPFS is one in a long line of ideas that didn't really work. Occasionally some of these ideas have massive success, like the Internet, and Bitcoin.
