CEVEX. Post-quantum cryptographic identity infrastructure for autonomous AI agents, anchored on Base. As machine economies scale beyond human oversight, unforgeable identity becomes the foundational primitive.

Cryptographic sovereignty at machine scale.

As autonomous agents proliferate across financial, logistical, and computational networks, the absence of verifiable identity introduces systemic risk at civilizational scale. CEVEX addresses this through the convergence of quantum physical entropy, post-quantum cryptography, and on-chain identity registration anchored to Base.

Classical public key infrastructure operates on the assumption of computational intractability. Fault-tolerant quantum computers will render this assumption obsolete within a predictable horizon. CEVEX preempts this vulnerability by deriving agent identities from measured quantum phenomena, producing keys whose uniqueness is guaranteed by the statistical irreducibility of quantum measurement outcomes rather than algorithmic complexity.

CEVEX extends post-quantum cryptographic primitives beyond conventional transaction signing into the full lifecycle of autonomous agent operations. The protocol stack encompasses entropy sourced key derivation, lattice based signature generation, trustless distributed verification, and long horizon key persistence, creating a coherent security envelope around every agent interaction from micropayments to governance critical protocol decisions.

Quantum physical entropy sourcing

CEVEX derives cryptographic keys from hardware level quantum processes, including photonic measurement and vacuum state fluctuation. Unlike pseudorandom number generators, which are deterministic given sufficient state knowledge, quantum entropy sources are nondeterministic by physical law, producing identities that are provably irreproducible.

Lattice based post-quantum signatures

CEVEX implements CRYSTALS Dilithium and FALCON signature schemes, both selected by NIST in the Post-Quantum Cryptography standardization process. These lattice based constructions provide security against Shor's algorithm and Grover's algorithm simultaneously, ensuring cryptographic integrity across both classical and quantum threat models.

Decentralized trustless verification

CEVEX's verification architecture eliminates the certificate authority model entirely. Signatures are standalone cryptographic artifacts verifiable by any Base network participant without querying a trusted third party. This removes single points of compromise while enabling verification throughput that scales with the network.

Core Technology

Key Generation

Keys derived from hardware quantum RNGs measuring irreducible physical phenomena. Entropy exceeds NIST SP 800-90B requirements, uniqueness bounded by physical law.

Agent Signing

Every agent action carries a post-quantum signature bound to a unique identity. Existential unforgeability under chosen message attack with built-in replay protection.

Trustless Verify

Direct signature validation with no dependency on certificate authorities or trusted intermediaries. Supports batch verification and zero knowledge compatible audit transcripts.

On-Chain Registry

Agent identities are registered as smart contracts on Base, providing a decentralized, append-only registry with Ethereum-secured finality. CRYSTALS Dilithium over module lattices ensures keys remain protected through the 2080 cryptographic horizon.
