This is a MUST read and probably the best article I have read that sums up the architecture behind signingroom.io and implications of the stateless architecture for private Bitcoin Coordination by Rich from rdctd.

It was an incredible experience attending Bitcoin Ireland Conference!
Meeting so many like-minded individuals and hearing from such a visionary lineup of speakers was truly energizing.
I want to extend a sincere thank you to the event organizer, Lawrence -stanley. He recognized the potential impact SigningRoom.io will have within the Bitcoin ecosystem and gave me the incredible opportunity to showcase it in the Exhibition Space.
A special shout-out to my great friend, Chris Lee, for joining me and providing invaluable support at the stall throughout the event.
Stateless Research was founded on a singular belief: that giving something truly important back to the world matters more than anything else. As this was the first conference I have ever attended, I felt it was only right to unveil this Irish creation on Irish soil. The "Zoom" of Multisig or should I say the "Signing Room" of Bitcoin Multisig! 😉
The support and encouragement I received from fellow bitcoin advocates, builders, educators, and podcasters throughout the weekend was a genuinely humbling experience.
Thank you to everyone who stopped by the stall, engaged with our mission, and offered such insightful feedback.
The world will be a better place when perfect money and digital rights are properly codified, enabling true digital sovereignty for everyone.
We’re just getting started.

Thanks for the support, I run my own lightning node on voltage for donations for signing room. Their LNBits version does not fully support Nostr. I will look into getting one setup with Nostr.

Big news for the sovereign tech stack. Stateless Research has been shortlisted as a finalist for the NI Cyber Community Awards! 🏆
We’re proving that zero-knowledge, ephemeral Bitcoin multisig coordination is the future of security. No footprints, no data-trails, just math.
Great to see the local NI ecosystem recognizing the importance of trustless infrastructure. ⚡️

Love what you're building with time-delays!
Improving OpSec is exactly what we are tackling right now. In fact, we’re dropping v2.1.0 tomorrow focused purely on the physical attack vector - specifically anti-shoulder surfing with a new frosted-glass privacy UI by default. Let us know if there is any more WebComponent hooks or killer features you might want in Signing Room.

Some personal news: After many years in traditional tech, I just pulled the plug. I am going full-time on digital sovereignty from today. ⚡️
Over the last few months, you guys have watched SigningRoom.io evolve from a weekend project into a100% free, stateless utility.
Today, I am launching the official umbrella and guardian for all of this:
Stateless Research.
SigningRoom remains the FOSS (AGPLv3), zero-knowledge public good for everyone.
Coordination without Custody.
Databases are liabilities.
Statelessness is security.

The room can have more than the signers join, so if someone wants to join the room and be a witness to the transaction (maybe for compliance reasons) they can label themselves as such so they will be in the downloadable audit which everyone can get in the room. No one has asked for these features, up until now I have been thinking of what people may want or be useful. This is optional of course you dont have to put a name to the session for privacy minded folks. I am planning to bring this forward as a BIP to get some formal feedback from the community very soon. If you have any feedback I am all ears. Thanks for replying (you actually are the first person to reply to a post)

Just shipped v1.3.0 of SigningRoom.io ⚡️
The problem: Getting a secure room link from your desktop to your mobile wallet without leaking metadata to a third-party chat app.
The fix: Secure QR Codes.
We added a "Security Curtain" QR modal—blurred by default to prevent shoulder surfing or screen-sharing leaks. Perfect for bridging air-gapped workflows visually.
Also included: Batch Verification for large input sets.
Stateless. Encrypted. Open Source (AGPLv3).

The whitepaper is live.
"The Stateless Pattern: Ephemeral Coordination as the Third Pillar of Digital Sovereignty"
We have formalized the cryptographic architecture behind SigningRoom.io
This paper details how we enforce UN Article 20 (Freedom of Assembly) not through policy, but through physics.
By utilizing ephemeral "Blind Relays" and client-side encryption, we prove that it is possible to coordinate high-value #Bitcoin multisig transactions without the server ever retaining user state.
Databases are liabilities. Statelessness is security.

I’ve decided to pivot Signing Room to a 100% free, stateless security utility for the #Bitcoin community. 🛡️
Deleted 30% of the code (removed all payment gates)
No accounts, no logs, no middleman
Purely ephemeral coordination in RAM
Multisig coordination should be a public good. If you're coordinating 2-of-3 or 3-of-5 sessions, you shouldn't have to leave a trail of sats or emails. Scaling security matters more than collecting sats
@jack @jb55 @nvk — I built this to solve the 'coordination friction' for multisig. Would love a technical eyes/audit on the statelessness.

I built this to solve the privacy leak in multisig coordination. It's a stateless, no-db 'War Room' for PSBTs that vanishes after 20 mins.

Under the hood of Signing Room 🏗️
I said the server is "blind" and "stateless." Here is the proof in the code.
📸 In this screenshot:
Line 642: The server only accepts encryptedData. It literally cannot read your PSBT.
Line 652: It immediately broadcasts the blob to the other signers. Nothing is saved.
Line 672: The alarm() triggers storage.deleteAll(). When the timer hits zero, the room (and all data) ceases to exist.
No database. No persistent logs. Just ephemeral Cloudflare Durable Objects.

Hey @nprofile…h36r , just wanted to say thanks for LNBits. ⚡️
I used it (via Voltage) to handle the payment logic for this stateless multisig room. The LNURLp extension made the integration trivial.
thought you might get a kick out of seeing it in the wild.

Signing Room: A stateless coordination layer for Bitcoin multisig.
I was tired of emailing PSBTs back and forth or trusting centralized servers with my transaction metadata. So I built a room that doesn't remember you.
🔒 Client-Side Encryption (Server sees blobs, not data)
👻 Ephemeral (Data auto-wipes after 20 mins)

It's free for standard usage. No accounts. No tracking.
