[Quantum @QuantumFDN]

Quantum's CEO @ivanmiskovic sat with @Alice__Bob's QEC lead @CVuillot on cat qubits, biased noise, and breaking RSA with 200x fewer qubits.

Congratulations to Alice & Bob on NVIDIA NVentures-backed extension of their €100 million Series B.

Full interview below.

[Dino @ledgersaur]

One of the best conversations we had with our guests on camera. Prof. Renner really knows how to make conversation both simple and interesting while providing immense value backed by his impressive experience and background in Quantum information theory .

Truly honored having him on a podcast. A must watch

[Dino @ledgersaur]

The signals in the market are all pointing in one direction. Preparing for the Q-day has become an essential showcase that you take digital asset security seriously

[Quantum @QuantumFDN]

Our CEO @ivanmiskovic sat down with Prof. Renato Renner to discuss the quantum threat to RSA, post-quantum cryptography for the next decade, and to unpack what quantum computing means for cryptography, security, and trust.

[Dino @ledgersaur]

The first podcast of the series

[Quantum @QuantumFDN]

The @GoogleQuantumAI whitepaper reshaped the quantum conversation.

We sat down with Benjamin Villalonga from @GoogleQuantumAI to walk through the full quantum computing stack from first principles - where the hardware meets classical simulation.

1 hour. Full conversation ↓

@rubenmarcus_dev AI acceleration (on all ends) regarding Quantum research is continuesly on the rise.
We happen to have a team member that is pushing it forward. Amazing effort Ruben

@rubenmarcus_dev @rubenmarcus_dev I wasnt expecting this. 3rd place was nice already. But top spot is really worth sharing

[Dino @ledgersaur]

@QuantumFDN @manel1874 @nillion @tectonicxyz welcome to the team @manel1874

[Dino @ledgersaur]

The first podcast from QIP, Riga is live.

We had a great time with Benjamin,
sat for an hour and explored quantum form his perspective

[Dino @ledgersaur]

@QuantumFDN The first in series of podcasts we have shot at QIP, Riga. More to come soon

[Dino @ledgersaur]

@hosseeb fully agree @hosseeb

welcome to @QuantumFDN

we make post quantum migration happen

[Dino @ledgersaur]

Devnet 2 brings quantum explorer to life: https://t.co/WCI5TK2Pnv

[Quantum @QuantumFDN]

Quantum Devnet 2 is live

Full post-quantum security at every layer.
Consensus, transactions, key management.
All quantum-resistant by default.

The way people find information is shifting from search engines to AI answer engines. Most websites aren't ready for that shift yet

aeo.js makes any site discoverable by ChatGPT, Perplexity, Claude, one npm install, fully open source.

Proud of the team on this one.

[Quantum @QuantumFDN]

We just launched AEO Checker

a free tool that tells you if your site is ready for the AI search era.

Check yours in 10 seconds.

@Cointelegraph $320B in stablecoins secured by cryptography that breaks under quantum attack. Sender stats are interesting, but custody security matters more when institutions ask if their assets survive to 2030. Post-quantum isn't a feature anymore, it's infrastructure.

[Dino @ledgersaur]

@WuBlockchain Lazarus took $2.02B in 2025 exploiting classical key infrastructure. Hot wallets running ECDSA are the attack surface. Fixing this requires cryptographic root changes, not just better ops. MCP threshold signatures and PQ custody primitives matter here.

[Dino @ledgersaur]

@0xManny4pf @QuantumFDN thanks, stay tuned for more

[Dino @ledgersaur]

@FlamezOnSol @QuantumFDN @stayymysti yes sir

[Dino @ledgersaur]

SPHINCS+ (SLH-DSA) signatures are 7,856 bytes. That's 121x ECDSA. ML-DSA-65 signatures are 3,309 bytes, roughly 51x.

On Arbitrum, L1 data posting is the dominant cost. At ~5.5 KB calldata per PQ UserOp with ML-DSA, you're looking at $2-8 per transaction. With SPHINCS+ you'd be north of $15-20, potentially more. That makes it unviable for any practical on-chain use today.

SPHINCS+ is hash-based and yes, arguably more conservative from a cryptographic assumptions standpoint. We agree. That's exactly why our Quantum L1 architecture supports SLH-DSA as a cosigner hedge: if lattice math ever breaks, there's a hash-based fallback that operates on an entirely independent mathematical assumption.
But for the primary signing scheme on an EVM smart wallet where users pay per transaction? ML-DSA-65 gives you NIST Level 3 security (192-bit) at a fraction of the size. It's the right trade-off between security and practicality.

[Dino @ledgersaur]

Yes, the Snap in this repo requires MetaMask Flask (developer build). It's one of three signing rails we shipped in the POC alongside a Rust CLI and a WalletConnect demo.

But the Snap is not our production path. We're building a standalone Chrome extension wallet with native ML-DSA-65 signing, no MetaMask dependency. Pure TypeScript using @noble/post-quantum. Passkey unlock, Google OAuth login, social recovery via on-chain guardians, ERC-4337 account abstraction through Kernel v3.

The user never interacts with ML-DSA directly. Onboarding feels like any modern smart wallet: create a password, optional biometric, optional social login. The PQ layer is invisible.
Testnet (Optimism Sepolia) is the first target. Base and Arbitrum follow.
The MetaMask Snap in the current repo is a proof that PQ signing can work inside the existing MetaMask architecture. The native wallet is what ships to users.
