Nixeon post-quantum payments chain

A lattice-native Layer 1 for payments that must outlive the cryptography that signed them. ML-DSA signatures verified on every input, a lattice state-commitment tree, 4-validator BFT. Post-quantum from the substrate up.

What replaced HAWK: ML-DSA, a live testnet, and the step it sets up

On 29 July we said HAWK was leaving our stack and that the replacement would be published separately. It is ML-DSA, and the chain running it is live: four validators, ML-DSA-65 for consensus, ML-DSA-44 for spends, over 136,000 blocks. Here is why we picked it, why an address now commits to several schemes at once, why we took the block prover off the node, and why this is deliberately a floor rather than a destination.

A new HAWK attack, and the redesign it pushed us into

On 28 July 2026 a HAWK key-recovery attack developed with Anthropic's Claude Mythos cut more than 40 bits off the claimed cost of breaking the signature scheme our chain runs on. Here is what the paper shows, what it does and does not mean for us, and the redesign we are adopting because of it.

NixProtocol's Post-Quantum Research Track

The signatures, key exchange, and KZG commitments every production chain depends on today do not survive a quantum computer. Privacy protocols have more to lose than most, because harvest-now-decrypt-later makes the migration deadline earlier than the 15-year quantum timeline suggests. Here is where we are betting, the stack we are building toward, and the honest cost accounting.

Post-quantum payments, open for design partners

Payments need post-quantum cryptography before the 2027 to 2033 migration deadlines, and Nixeon is where we are building it. The testnet is open for design partners. NixPay brings zero-knowledge privacy to EVM chains today and is live on Avalanche Fuji and Base Sepolia.
