Will keep you updated on the latest news about
Post-Quantum world. And yes, @drakefjustin we also think it's more as an opportunity than a hurdle.

Ethereum Researcher @drakefjustin, who co-authored Google's recent quantum paper:

"I've stopped thinking about post-quantum as a hurdle that we have to overcome, and I think of it more as an opportunity. It's an opportunity for Ethereum to stand out as the very first global financial system that is post-quantum secure — not just relative to its competitors, but also relative to fiat."

The path to real Post-Quantum era is incoming.

[Grayscale @Grayscale]

Grayscale Research's analysis of the @Google Quantum AI paper suggests breakthroughs may come in sudden leaps, not gradual steps. That means preparation can’t be delayed.

The good news:
• Post-quantum cryptography already exists
• Some chains like $SOL and $XRP Ledger are experimenting
• The path forward is technically clear

It's an opportunity for Ethereum to stand out as the very first global financial system that is post-quantum secure — not just relative to its competitors, but also relative to fiat and tradfi."

Justin also believes quantum presents an opportunity for Ethereum to become the best version of itself: “The move to post-quantum is essentially a rewrite, and that’s a massive opportunity to start with a clean slate and wipe our technical debt.”

The rewrite bundles post-quantum security with a new ZK virtual machine (LeanVM) that can snarkify the entire consensus layer in real time. The result is that the Ethereum L1 can scale to 10,000 TPS at 1 gigagas/second — while simultaneously becoming quantum-secure.

Post-Quantum is surely gonna hit the blocks on every chain.

Check you Solana wallets on https://t.co/oxHfOuxatY and see if they are Quantum hack exposed.

[Ethereum Daily @ETH_Daily]

Solana just stress-tested post-quantum signatures on its testnet with Project Eleven — and the results are sobering.

Signatures became 20-40x larger, and network performance dropped by ~90%.

Worse: Solana’s architecture exposes public keys on-chain, meaning 100% of wallets are vulnerable to future quantum attacks that could crack Ed25519.

This experiment lays bare crypto’s brutal trade-off: you can have quantum resistance, or you can have speed. Not both.The quantum era isn’t coming. It’s approaching faster than most chains are willing to admit.

What is Post Quantumize and why does it exist?

Every time you send a crypto transaction, your public key gets permanently recorded on-chain.

Quantum computers, once powerful enough, can mathematically reverse-engineer your private key from that public key.

Recent research shows this could happen with under 500,000 qubits. Possibly by end of decade.

Post Quantumize is a free tool that checks if your wallet's public key is already exposed.

Paste any ETH, BTC, SOL or L2 address.
Get a real risk score based on live blockchain data.
No wallet connection. No sign up. Just answers. It is now ENS and .SOL compatible.

Think of it as a smoke detector for your wallet.
It doesn't stop the fire. It tells you if you're at risk so you can act now while there's still time.

This is v1. We're building toward a full post-quantum migration guide showing people exactly what to do when their wallet is exposed.

Today is a monumentous day for quantum computing and cryptography. Two breakthrough papers just landed (links in next tweet). Both papers improve Shor's algorithm, infamous for cracking RSA and elliptic curve cryptography. The two results compound, optimising separate layers of the quantum stack. The results are shocking. I expect a narrative shift and a further R&D boost toward post-quantum cryptography.

The first paper is by Google Quantum AI. They tackle the (logical) Shor algorithm, tailoring it to crack Bitcoin and Ethereum signatures. The algorithm runs on ~1K logical qubits for the 256-bit elliptic curve secp256k1. Due to the low circuit depth, a fast superconducting computer would recover private keys in minutes. I'm grateful to have joined as a late paper co-author, in large part for the chance to interact with experts and the alpha gleaned from internal discussions.

The second paper is by a stealthy startup called Oratomic, with ex-Google and prominent Caltech faculty. Their starting point is Google's improvements to the logical quantum circuit. They then apply improvements at the physical layer, with tricks specific to neutral atom quantum computers. The result estimates that 26,000 atomic qubits are sufficient to break 256-bit elliptic curve signatures. This would be roughly a 40x improvement in physical qubit count over previous state-of-the-art. On the flip side, a single Shor run would take ~10 days due to the relatively slow speed of neutral atoms.

Below are my key takeaways. As a disclaimer, I am not a quantum expert. Time is needed for the results to be properly vetted. Based on my interactions with the team, I have faith the Google Quantum AI results are conservative. The Oratomic paper is much harder for me to assess, especially because of the use of more exotic qLDPC codes. I will take it with a grain of salt until the dust settles.

→ q-day: My confidence in q-day by 2032 has shot up significantly. IMO there's at least a 10% chance that by 2032 a quantum computer recovers a secp256k1 ECDSA private key from an exposed public key. While a cryptographically-relevant quantum computer (CRQC) before 2030 still feels unlikely, now is undoubtedly the time to start preparing.
→ censorship: The Google paper uses a zero-knowledge (ZK) proof to demonstrate the algorithm's existence without leaking actual optimisations. From now on, assume state-of-the-art algorithms will be censored. There may be self-censorship for moral or commercial reasons, or because of government pressure. A blackout in academic publications would be a tell-tale sign.
→ cracking time: A superconducting quantum computer, the type Google is building, could crack keys in minutes. This is because the optimised quantum circuit is just 100M Toffoli gates, which is surprisingly shallow. (Toffoli gates are hard because they require production of so-called "magic states".) Toffoli gates would consume ~10 microseconds on a superconducting platform, totalling ~1,000 sec of Shor runtime.
→ latency optimisations: Two latency optimisations bring key cracking time to single-digit minutes. The first parallelises computation across quantum devices. The second involves feeding the pubkey to the quantum computer mid-flight, after a generic setup phase.
→ fast- and slow-clock: At first approximation there are two families of quantum computers. The fast-clock flavour, which includes superconducting and photonic architectures, runs at roughly 100 kHz. The slow-clock flavour, which includes trapped ion and neutral atom architectures, runs roughly 1,000x slower (~100 Hz, or ~1 week to crack a single key).
→ qubit count: The size-optimised variant of the algorithm runs on 1,200 logical qubits. On a superconducting computer with surface code error correction that's roughly 500K physical qubits, a 400:1 physical-to-logical ratio. The surface code is conservative, assuming only four-way nearest-neighbour grid connectivity. It was demonstrated last year by Google on a real quantum computer.
→ future gains: Low-hanging fruit is still being picked, with at least one of the Google optimisations resulting from a surprisingly simple observation. Interestingly, AI was not (yet!) tasked to find optimisations. This was also the first time authors such as Craig Gidney attacked elliptic curves (as opposed to RSA). Shor logical qubit count could plausibly go under 1K soonish.
→ error correction: The physical-to-logical ratio for superconducting computers could go under 100:1. For superconducting computers that would be mean ~100K physical qubits for a CRQC, two orders of magnitude away from state of the art. Neutral atoms quantum computers are amenable to error correcting codes other than the surface code. While much slower to run, they can bring down the physical to logical qubit ratio closer to 10:1.
→ Bitcoin PoW: Commercially-viable Bitcoin PoW via Grover's algorithm is not happening any time soon. We're talking decades, possibly centuries away. This observation should help focus the discussion on ECDSA and Schnorr. (Side note: as unofficial Bitcoin security researcher, I still believe Bitcoin PoW is cooked due to the dwindling security budget.)
→ team quality: The folks at Google Quantum AI are the real deal. Craig Gidney (@CraigGidney) is arguably the world's top quantum circuit optimisooor. Just last year he squeezed 10x out of Shor for RSA, bringing the physical qubit count down from 10M to 1M. Special thanks to the Google team for patiently answering all my newb questions with detailed, fact-based answers. I was expecting some hype, but found none.

Many are wondering "what Google saw" that caused them to revise their post-quantum cryptography transition deadline to 2029 last week. It was this:

https://t.co/dQtmTK9pdz

[RYAN SΞAN ADAMS @RyanSAdams]

Google just released a warning for cryptocurrency that the number of qubits required to break ECDSA is 20x less than previously thought.

They have proof.

They’re (strongly?) recommending crypto upgrade to post-quantum by 2029 now.

4 years!?

Timelines are accelerating rapidly.
