This was a reply to pavlenex's post regarding companies funding FOSS R&D, with some good discussion to follow
https://x.com/pavlenex/status/2049122238033531339

2026-04-29 06:39:42 UTC

Something I've been contemplating regarding open source funding is that it is substantially harder to secure open source funding if you intend to build a profitable business atop the FOSS you're producing.
We did not pursue some grants ourselves because we'd been told that commercial companies are unsuitable recipients. I respect this stance and I think the instinct behind it is well-meaning, but in my opinion it produces outcomes opposite to what open source donors desire.
This reasoning seems to come from various angles. One is charitable instinct: funding should go to those who otherwise wouldn't receive it. The other is distributive: why fund work that someone else intends to monetise. Both are intuitive. But I'd argue that this creates market distortions that are suboptimal for the ecosystem we want to foster.
FOSS projects with commercial incentive are subject to falsifiable product exploration -- continuous, unforgiving feedback from users. Skin in the game. This selection pressure produces better software and products optimising for grant approval.
Bounty style funding results in even more perverse outcomes: a prize for acheiving X often results in the minimal viable X without any regard for usability, adoption or longevity. They win the prize and move on.
The current funding environment favours more hobbyist-style maintainers and well-capitalised ventures and squeezes out the middle: small commercial teams shipping FOSS, who I think may be the healthiest part of the open source ecosystem.
In Bitcoin hardware, at the extremes, "company" and "business" are even used as pejoratives, as though commercial intent is antithetical to open source values! They would argue this suspicion is founded through historical events in the industry. Perhaps, but I think is unreasonable to apply broadly.
In terms of our own work: we've delivered a substantial body of FOSS code (used by others), specification contributions, research, and industry vision, and in my (biased) opinion, the best hardware wallet in Bitcoin's existence. I can say with certainty that this output would have been faster, larger, and more impactful with funding (earlier, wen FROST?) in this middle ground between entirely donor funded FOSS and fully capitalised proprietary development.
Meritocracy works when the field is open to everyone advancing it -- including those building businesses on top of the FOSS they produce. Would be curious as to people's thoughts

fwiw FROST doesn't **need** two rounds, the RO in FROST stands for "Round Optimised" whereby FROST nonces can be pre-cached in order to sign in a single round of communication (or replenished alongside signature shares like we do at @nprofile…8fv9).

The backup wouldnt fit into a regular BIP39 24 word backup. With FROST backups it is preferable to include some additional data inside that improves recovery: compatible share detection, no trusted xpub problem when recovering on multisig.

Cryptography and security are difficult for non-specialists to evaluate, which is why external audits are often seen as a source of reassurance. In practice though, the bigger risks for most people come from keeping life savings in a single-signature wallet at home, or from complex backup processes in traditional multisig setups.
Frostsnap has not yet undergone an external audit, similar to most hardware wallets at an early stage. That said, our design choices already reduce many common risks. By using advanced modern cryptography, Frostsnap enables multiple devices (your phone and signing devices) to each contribute entropy, with both sides verifying it. This makes the usual critical mistakes such as weak randomness or flawed key generation extremely difficult.
We also build exclusively in memory-safe programming languages, eliminating an entire class of vulnerabilities that have historically affected wallets written in C or C++.
Every change goes through careful peer review, and as Frostsnap adoption grows, the number of independent eyes on the code will only increase.

1. Currently priced in sats so depends if you mean increase in dollar term. Possibly. TBD.
2. Other HWWs can't do FROST, infinitely worse multisig experience and drawbacks.
3. No one loses bitcoin to laser and power glitching attacks. Frostsnap's security model focuses on your ability to visit T-of-N devices.
4. Yes we'll be encouraging other FROST teams to be compatible with us and our code is available to integrate with.
5. Our displays allow for onscreen device confirmation and backup entry.
6. Probably just so people stop focusing on secure elements. It's not that important in our security model and people misunderstand the security guarantees they provide.

Good question (and yeah we need to put more out there), so the FROST multisig only has a single group public key (one xpub). And this single group public key can be reconstructed from secret shares or their images. That means that so long as you have two devices or their backups, you can find the xpub and simple derivation path -> descriptor.

Secure elements are really just secure PIN checkers that release decryption keys. When I was naive I thought the signing operations occur off the main MCU and in a secure enclave, but this is not the case with most hardware wallets. A successful PIN releases a decryption key which then passes onto the main chip to decrypt the secret key in memory.

2025-07-01 01:20:29 UTC

- reply

Frostsnap's security model primarily focus on the ability for you, or an attacker, to visit T-of-N devices.
The Frontier model does not have a secure element. However we do encrypt the secret stored on the device using a decryption key held in the phone's secure element. This means you need to unlock your phone to sign or access anything useful, so by extension, protecting the device secret behind the phone's secure element.
Now you may be wondering about recovery, what if you lose the phone and its decryption key? If that happens you can take a new phone to visit T-of-N devices, reconstructing the decryption key! Now you're ready to go signing again!
