SQIsign is the only isogeny-based scheme in the process. Isogeny schemes derive security from the hardness of finding maps between supersingular elliptic curves with the right algebraic structure. SQIsign has the smallest combined public-key and signature sizes of any candidate, with 148-byte signatures at security category 1. Between rounds, the team improved signing speed by approximately 20× and verification by approximately 6×, and produced a cleaner security argument in the random oracle model. SQIsign still has higher latency than the other candidates, and fully constant-time signing remains open. NIST flagged side-channel resistance and broader community analysis of the underlying endomorphism-ring assumption as Round 3 priorities.

@projecteleven @preciouschigo9 @conordeegan Any isogenies based?
Waiting for an isogeny based to make it to the round up after the flag bearer "SIKe" was broken by a classical attack.
English
🚨 NIST announced the third-round candidates of the Additional Digital Signatures process. 9 schemes move forward and 5 do not.
Moving forward:
- SQIsign
- HAWK
- FAEST
- MQOM
- SDitH
- UOV
- MAYO
- QR-UOV
- SNOVA

🔶Simple guide on how to install the Quantum Vault by @projecteleven and protect your BTC from future quantum threats 🧵 ⛓️ Visit: github.com/p-11/quantum-v… 1/ Download the `chrome-extension.zip` file from the latest release and unzip it. 2/ Open `chrome://extensions/` 3/ Turn on Developer Mode 4/ Click Load unpacked and select the unzipped Quantum Vault folder. That’s it , Quantum Vault will install automatically ✅ Works on Chrome and Chromium-based browsers like Brave, Edge, and Arc. After installing, I copied my BTC address to check whether it’s safe against potential quantum attacks. Check yours here: projecteleven.com/quantum-vault This isn't a sponsored post

I think this is very important
They are NOT saying: “Use this wallet with thousands of dollars.”
They’re saying: “Here is a working model showing how this can be done.”
To help researchers, developers, protocols, ecosystem experimentation.
Right @projecteleven ?

Super proud of the team on this one. Having an open-source, MIT-licensed reference implementation that's been audited (twice) is rare, and as a security company that's the bar I think we should hold ourselves to.
As more and more AI code and AI applications get shipped, security is degrading at a rapid rate. High quality reference implementations to build on top of are becoming a security necessity.

Quantum Vault - An audited reference implementation for account abstraction Post-quantum readiness must be achieved at all layers of the stack. We’ve worked with protocols on post-quantum testnets and hybrid signing models, deployed yellowpages as an attestation service for Bitcoin migration, proposed and optimized PQC algorithms, and proved BIP32 HD Wallets can work in a post-quantum world. Today, we are releasing our latest contribution to the open-source blockchain community: two repositories on GitHub under Project Eleven. Libqc is a TypeScript SDK for ERC-4337 account abstraction with parallel Bitcoin support, and quantum-vault is a browser-extension vault built on libqc. Both are MIT-licensed and have been audited by Cure53. They are reference implementations; not production wallets. Try out Quantum Vault today! ⬇️⬇️⬇️

The repos can be found on our Github; github.com/p-11/libqc and github.com/p-11/quantum-v…. Issues and pull requests welcome.

@NoahN13811 @coinbureau Common misconception. Blockchains are most at risk, and the rest of the internet is already migrating quickly.

People keep saying quantum computing will destroy Bitcoin and crypto.
But if a tsunami hits, the first places underwater are the cities closest to the shore.
What I mean is simple:
If quantum technology ever becomes powerful enough to seriously threaten Bitcoin, then the global banking system, military encryption, government infrastructure, and most modern cybersecurity would already be compromised long before Bitcoin collapses.
That argument ignores reality.
And unlike traditional financial systems, Bitcoin is open-source.
Its network can evolve. If quantum resistance becomes necessary, the community can coordinate upgrades and adapt the protocol over time.
English
🚨QUANTUM THREAT TIMELINE MOVES CLOSER
A new report says “Q-Day,” when quantum computers could break modern encryption, may arrive as early as 2030.
A breakthrough is seen as “more likely than not” by 2033.
English
@SlotWinX @projecteleven fair enough. ignore it until it becomes a problem 😀
English
Are your $ETH and $SOL bags actually safe from quantum computers?
New report by @projecteleven says 65% of Ethereum and 100% of Solana addresses are quantum-vulnerable right now.
Q-Day could hit as early as 2030.
How many of you have even thought about this?

Excited to announce the 2026 @ProjectEleven Quantum Threat to Blockchains report.
I'm confident this is the most comprehensive resource you'll find on the intersection of quantum x blockchain infrastructure vulnerability.
