Building iroh with the amazing folks at number 0 (n0.computer). Generally striving to increase user agency and excited about commons networks. Only works for Canadian CEOs, apparently. Rust, cryptography, CRDTs & more on my feed

yep!

W/o chunk groups, you're filling the buffer up only up to 1024 plus a bunch of layers from the Merkle proof relative to the root. W/ chunk groups you fill it up to 16KiB plus the proof. But on the proof level you could again transmit a set of say 64 chunk group hashes at once and derive parents

@Oct 8, 2026, 9:07 PM

There's another thing I've always thought about but never implemented: in theory we could leave out layers in the Merkle Tree again above the chunk groups: what you actually care about is having an "unverified integrity byte buffer size".

😂 I wonder now, is the NL one wrong though?

Not gonna RS the thread that made me think about this (you've likely already seen it, or a similar one) BUT Every person I know who has cut off or gone low contact with a parent took YEARS of agonizing and trying to make things work because damn that's their PARENTS.

If you ever wondered why visible light is those particular wavelengths, it's because life evolved to see in the narrow range where water is transparent

Err wtf this is big?

@Oct 2, 2026, 3:29 PM

It's always about "what can you train the models at?". It's hard to RL this question. I also think it's hard to RL maintainability, although perhaps a little easier.

Gufo is pretty impressive. Running Qwen 3.8 Flash Next on my strix halo machine locally is now feels entirely differently:
llama.cpp: ~400 t/s prefill, ~20-24 t/s tg (no mtp, it's consistently slower)
gufo: ~1300 t/s prefill, ~30-40 t/s tg (with mtp-7)

There are some interesting ideas for future jobs by modern monetary theory proponents: The Job Guarantee. The idea is to have the government fund community or care work at livable wages.

We have released a new version of
@iroh.computer.

Nothing major in terms of features, but we did manage to significantly reduce the binary size.

So now my entire embedded device zoo is running on iroh from crates.io. No more patch needed.

Relatable. For real though, do you think it might get activated because of the word "execute"?

@iroh.computer
Was "Dial Keys, not IPs" inspired by reticulum.network? And what would be the differences between them?

Reticulum does not use source addresses. No packets transmitted include information about the address, place, machine or person they originated from.
There is no central control over the address space in Reticulum. Anyone can allocate as many addresses as they need, when they need them.
Reticulum ensures end-to-end connectivity. Newly generated addresses become globally reachable in a matter of seconds to a few minutes.
Addresses are self-sovereign and portable. Once an address has been created, it can be moved physically to another place in the network, and continue to be reachable.
All communication is secured with strong, modern encryption by default.
All encryption keys are ephemeral, and communication offers forward secrecy by default.
It is not possible to establish unencrypted links in Reticulum networks.
It is not possible to send unencrypted packets to any destinations in the network.
Destinations receiving unencrypted packets will drop them as invalid.

We just ended up realizing that dialing by key alone is already a super useful abstraction. Maybe more things should be built like this. I'm glad to see that's how reticulum is designed as well. Not sure about exact differences. Someone would have to educate me on reticulum.

@Sep 27, 2026, 12:15 PM

It wasn't! We aren't actually super familiar with reticulum and we weren't when we named it. The concept mostly came out of a need for stable addressing in a world where neither IP nor DNS was possible to address a device adequately and securely.

I swear @iroh.computer is erasing basically every network annoyance I could have possibly encountered when ideating about decentralized systems

@Sep 22, 2026, 11:07 AM

No. But you only need to give it one more piece of information: the relay URL (or the DNS pkarr server to resolve it, but at that point the relay URL is likely easier)

@Sep 22, 2026, 10:01 AM

Relays don't have "a table" and don't use any pkarr mechanisms which is why I can't parse your last question.
