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.

Introducing NIX Protocol: Private Transactions on Any EVM Chain

Public blockchains have a privacy problem. Every transaction is permanent public data. Wallet addresses become identities. We built NIX Protocol to fix this - a lightweight set of smart contracts that adds privacy to any EVM chain without leaving the chains you already use.
