Zk technology is constantly evolving. I’m on the lookout for the most noteworthy news and innovations in this field. Today, I’d like to introduce you to Xion.
One day, a blockchain transaction could be marked VALID even though its owner never approved it.
That's one reason quantum computing worries security researchers. A sufficiently powerful quantum computer could break some of the digital signature schemes used today, allowing an attacker to forge signatures for vulnerable accounts.
We're not there yet. But in March 2026, Google Quantum AI estimated that breaking the elliptic-curve cryptography used by $BTC and $ETH might require roughly 20 times fewer physical qubits than earlier estimates suggested.
On October 28, $VERONA activated Fermi v32, adding two NIST-standard post-quantum signature options: ML-DSA-65 and SLH-DSA-128s.
What caught my attention was the account design.
Verona accounts are smart contracts with replaceable signing methods. A user can add a post-quantum key, revoke an older classical key, and keep the same address, funds and transaction history.
Think about how much depends on a single address: apps, payments, permissions, and eventually AI agents acting on someone's behalf. Changing the keys without rebuilding those connections could save a lot of trouble.
It's not a finished migration. The protection is opt-in, and validator keys and consensus are planned for Fermi Phase 2. Post-quantum signatures won't prevent phishing or every other kind of attack, either.
Adoption is still the real test for VERONA. But I think this is the right question for any chain planning to be around for decades:
When it's time to change the locks, will users have to move out?
