News from Quantum Realm

From today's viewpoint, no, Dogecoin, nor its native DOGE token are safe from being broken into by a strong enough quantum computer. It signs transactions with ECDSA on secp256k1, which the same curve Bitcoin uses, and it's breakable by a quantum computer via Shor's algorithm.

Right at this particular moment, the Cardano blockchain and ADA can't be described as quantum-safe. The network's ordinary key-controlled transactions use Ed25519, and block production uses Ed25519-based KES, all of which a capable enough quantum computer could break, once it appears on the scene.

Solana isn't quantum-safe today. Its ordinary accounts and its validators sign with Ed25519, an elliptic-curve scheme that a large enough quantum computer could break, and because an ordinary Solana address is the public key itself, that key is on display as soon as the address is known. Solana has an opt-in hash-based vault project designed for quantum-resistant authorization and published migration research, but the base chain hasn't moved to post-quantum signatures.

XRP isn't quantum-safe today. Its underlying blockchain, the XRP Ledger, signs transactions with secp256k1 or Ed25519, both elliptic-curve schemes that a large enough quantum computer running Shor's algorithm could break. Ripple, the company overseeing it all, has a published plan to fix that by 2028, and the mainnet hasn't adopted a post-quantum signature yet.

Your HYPE tokens aren't at risk from a quantum computer today, because no publicly demonstrated machine can break the underlying cryptography at the required scale. But ordinary HYPE accounts, like almost all crypto, are secured by elliptic-curve signatures that a large enough quantum computer could break, and no public migration plan appears in Hyperliquid's documentation yet.

Storing your crypto carefully is sound practice, but against a quantum computer, it mostly misses the point. The quantum threat isn't someone stealing your key out of storage. It's a future scenario in which a capable enough machine could derive your private key from a quantum-vulnerable public key available to the attacker, whether disclosed on-chain or elsewhere. Therefore, quantum-safe storage needs a careful definition before you shop for it.

No, Hyperliquid isn't quantum-safe today. Its HyperCore user actions and HyperEVM transactions rely on Ethereum-compatible elliptic-curve signatures that a sufficiently capable quantum computer could forge. This guide covers where Hyperliquid's quantum exposure sits and what HYPE holders can do about it.

Ethereum isn't quantum-resistant today. Its standard externally owned accounts sign transactions with elliptic-curve cryptography, and its validators sign with a related scheme. Both can be broken by a capable enough quantum computer. That said, Ethereum has one of the most active post-quantum migration efforts of any major chain. This guide covers why Ethereum is exposed and what its roadmap proposes, as of September 2026.

A quantum-resistant blockchain is built to stay secure against a cryptographically relevant quantum computer, the kind that could someday break the public-key signatures securing today's accounts. The exposed layer consists of those transaction signatures, which prove you authorized a spend. The rest of the chain, including the hashing that secures mining and links blocks, is in far better shape, though not invulnerable.

The first quantum-safe vault available to everyone has passed independent security audits Panama, September 22, 2026 — qLABS, a quantum-native Web3 foundation, today announced that qVAULT.xyz, the first vault to make post-quantum protection available to any holder of digital assets, has completed independent security audits of both its smart contracts and its post-quantum cryptography by Fairyproof and TechsLayers. qVAULT.xyz is live on Hyperliquid's HyperEVM, where it protects HYPE and its native token qONE against the emerging quantum threat to digital assets way before any major blockchain is expected to migrate its own cryptography.
