Quantum Lab: will crypto survive a quantum computer?

Every crypto wallet proves "this is really me" with a digital signature. A big enough quantum computer could one day fake today's signatures. New quantum-safe signatures already exist. Try both below: this is real cryptography, running only in your browser.

Ed25519

The signature Solana uses now (also many other blockchains).

ML-DSA-65

Official US standard since August 2024 (NIST FIPS 204).

Falcon-512

Smaller signatures. The one Solana developers picked for their quantum plan (2026).

What if a big quantum computer existed? Switch one on in the simulation and see which signatures still hold.

Honest note: the keys and signatures above are real and made on your device; nothing is sent anywhere and you can't use them for a wallet. The quantum computer is a simulation: nobody can break Ed25519 today.

The quantum problem in four steps

  1. A signature proves it's youYour wallet has a secret key and a public key. Only the secret key can sign; everyone can check with the public key.
  2. Today it's one-wayGoing from the public key back to the secret key would take normal computers longer than the age of the universe.
  3. Quantum changes thatA large quantum computer running Shor's algorithm could do it. Such a machine does not exist yet; experts disagree on when it will.
  4. The fix: new mathPost-quantum signatures like ML-DSA and Falcon use problems quantum computers can't shortcut. They are bigger, but they work.

Myths, answered straight

"AI can make a blockchain quantum-safe."

No. AI can help find bugs in code, but it is not a lock. Safety comes from proven math (like the standards in this lab) and careful audits. Be careful with any project that says "secured by AI".

"We need a quantum computer to stay safe from quantum computers."

No. Quantum-safe signatures run on normal phones and laptops, as you just saw. Quantum key distribution exists too, but it needs special hardware and doesn't help a blockchain.

"Quantum computers will break crypto tomorrow."

Not tomorrow. Today's quantum computers are far too small. But blockchains move slowly, so big networks like Solana are preparing now.

"Is $MAIGA quantum-safe?"

Not yet, just like every Solana token today. $MAIGA lives on Solana, so it gets quantum safety when Solana upgrades its signatures. We will not claim more than that. Entertainment only. NFA. DYOR.

Facts checked October 2026: NIST published FIPS 203, 204 and 205 in August 2024; Falcon is being standardised as FN-DSA; Solana developers announced Falcon as their post-quantum signature in 2026.
