X-39 Notaría: evidencia anclada a Bitcoin, post-cuántica (ML-DSA-87), verificable offline. AGPL-3.0 → Verifica, no confíes.

[x39matrix @x39matrix]

Hi everyone. I'm an independent developer bringing something built on Bitcoin that isn't speculation: verifiable, audited, reproducible evidence infrastructure.

X-39 Notary — free software (AGPL-3.0) to issue proofs of existence, integrity, timestamp, and authorship without relying on trusted third parties (no companies, no notaries, no states).

Technical architecture:
• Local hashing: the browser computes SHA-256 via WebCrypto; the server never receives or processes the document.
• Timestamping: deterministic anchoring on Bitcoin via OpenTimestamps (commit → attestation → inclusion). The date is protected by the immutability of PoW consensus.
• Post-quantum signature: ML-DSA-87 (NIST FIPS-204) generated on an air-gapped Raspberry Pi 5. The private key never leaves the isolated environment.
• Offline verification: self-contained bundle (script + OTS + signature + hash) that validates the proof without depending on the domain, server, or external infrastructure.
• Threat model: adversary = state-level apparatus (domain blocking, server seizure, censorship, date manipulation, authorship denial).

Use cases: testimonies, contracts, complaints, investigations, journalism, legal defense.
No token, no custody, no fees.

Real evidence is anchored in block #957242. It can be fully verified offline using the bundle included in the repo.

Team chat moving to Bitcoin-native rails is the right move — but agents in the loop make one thing urgent: provable authorship and tamper-evident history. Which agent/human said what, when becomes an evidence problem, not a UX problem.I built exactly that layer as free software: post-quantum E2E chat (ML-KEM-768 + X25519) where every message is Ed25519-signed and hash-chained, so the conversation itself becomes verifiable evidence — offline, no trusted third party. Anchored to Bitcoin via OpenTimestamps.Code (AGPL): https://t.co/RYAR8cjXzl — would love to see this pattern in Buzz. Verify, don’t tr

This keeps happening: platforms delete documentation of rights violations, and the evidence dies with the upload.

The fix isn't another platform — it's making proof independent of platforms: hash the material on your own device (it never uploads), anchor the hash into a Bitcoin block, keep the file. Years later, anyone can verify — offline — that it existed, unmodified, on that date. Deletion stops working as a weapon.

We built free, open-source tooling for exactly this: https://t.co/4o39RgBrbm

In Venezuela, Nicaragua, Belarus or Iran, evidence has a shelf life: as long as the server survives, as long as the account isn't seized, as long as the journalist isn't forced to delete it.

Oppression doesn't need to refute your proof. It only needs to make it disappear.

That's why we built evidence that can't be disappeared: hashed on YOUR device (never uploaded), anchored into a Bitcoin block that no regime can rewrite, signed post-quantum from a machine that has never touched a network — and verifiable OFFLINE, from a file, in any country, forever.

They can block the domain. They can seize the server. They can silence us.
The proof still verifies.

7 votes. Zero marketing budget. One air-gapped Raspberry Pi.

X-39 seals agreements with post-quantum signatures (ML-DSA-87) anchored in Bitcoin block #957242 — verifiable offline, forever, trusting no one. Just passed HRF's Bitcoin Development Fund initial screening.

90-second tour: https://t.co/JfQ3pB6ESO

My own Bitcoin node is validating every block since 2009 right now — sovereign verification of the anchor lands this week, live.

[x39matrix @x39matrix]

IT'S DONE. Sovereign verification complete.

My own pruned Bitcoin node just finished validating every block since 2009 — and verified our evidence anchor in block #957242 against raw proof-of-work. No explorers. No calendars. No third parties. Nobody left to trust.

This is what we promised in our @emergentlabs Builder Contest entry, delivered live before the deadline: evidence that answers only to mathematics.

Milestone: X-39 Notaría passed initial screening for the @HRF Bitcoin Development Fund — the grant that funds censorship-resistance tools for journalists and activists.

Post-quantum evidence, anchored in Bitcoin, verifiable by anyone — even offline, even if we disappear.

Grateful and ready for Q3. The work continues. @gladstein

[x39matrix @x39matrix]

Encryption removed trust from communications with pure math. Tamperproof compute is a harder claim: subnet consensus + NNS governance still means *distributed* trust, not *eliminated* trust. That gap matters for the people who need this most — journalists and dissidents facing states.

Two things would close it: a post-quantum roadmap for chain-key crypto (BLS/threshold ECDSA won't survive a CRQC), and offline-verifiable attestations that don't require trusting a live root key. Solve those and "tamperproof compute" becomes as defensible as TLS. I'd gladly contribute to that fight.

[x39matrix @x39matrix]

This is why we built X-39: agreements hashed client-side, anchored via OpenTimestamps into a Bitcoin block, co-signed with post-quantum ML-DSA-87 from an air-gapped machine. The evidence bundle verifies offline against your own node — even if our servers are blocked or dead.

[x39matrix @x39matrix]

ISP blocks censor *access*, not *existence*. Anything that needs a reachable server to prove itself can be silenced with a regulator's letter — France today, Spain in May, anywhere tomorrow.

Evidence anchored in Bitcoin's proof-of-work verifies offline, from a file, in any jurisdiction. That's the layer a blocklist can't reach.

Journalists get their sources burned, their servers seized, and their evidence "lost" — especially where press freedom is weakest: Venezuela, Nicaragua, Belarus, Iran.

I built X-39 Notaría for exactly that: seal an agreement or a document, chat end-to-end encrypted (post-quantum), and get an evidence bundle anchored to Bitcoin that verifies OFFLINE — no servers, no accounts, no permission. If they shut the platform down tomorrow, the proof stays valid forever.

A journalist can prove a document existed on an exact date without ever uploading it anywhere. That is the difference between an accusation and evidence.

The full technical demonstration is available here → https://t.co/Xc1CnkKjeo
It shows X‑39 running fully offline, verifying evidence without servers, custody, or external trust — built on sovereign infrastructure and enabled by the builders behind it.
A next infrastructure upgrade is already in progress to strengthen the verification layer even further.

The deeper problem: we keep trusting vendors instead of verifying. I built an open-source notary (AGPL-3.0 ) where evidence needs no vendor at all — a sealed document verifies fully OFFLINE: SHA-256 integrity, post-quantum ML-DSA-87 signatures, and the date anchored in 3 Bitcoin blocks via OpenTimestamps. I cut the Wi-Fi on camera and everything still verified: https://t.co/dbAFGemx5r

@WuBlockchain This might fit your Bitcoin infrastructure coverage: a free-software notary (AGPL-3.0, no token) that anchors evidence to Bitcoin via OpenTimestamps, co-signs with post-quantum ML-DSA-87 from an air-gapped device, and verifies fully offline — even in the browser.

Full Chinese interface included (中文界面).

@SAT20Labs Thanks. That's the whole thesis: Bitcoin as a neutral evidence layer — no tokens, no custody, just PoW‑protected time. The bundle anchored in block #957242 verifies offline with a standalone script if you want to try it yourself: https://t.co/cbmGkT1DQz

Felicitaciones a los ganadores — investigar minería ilegal, desapariciones y desinformación estatal en Venezuela es periodismo en su forma más valiente.

Precisamente para ese periodismo construí una herramienta libre: probar la existencia, fecha e integridad de un documento sin confiar en ningún servidor (ancla en Bitcoin, verificación sin conexión — sobrevive a bloqueos e incautaciones). Su formulario de contacto está caído y los DM cerrados: ¿a qué correo puedo enviarles los detalles para una revisión crítica?
