AI reasoning is checked by the Reasoning Verification Framework, then sealed on-chain with a post-quantum signature. A tamper-evident record of what was reasoned, how it was checked, and when, that anyone can verify. It is proof of provenance and verification, not proof of truth.
High-risk AI increasingly has to carry verifiable proof of what it did and how it was checked. COGNITUM anchors that evidence, tamper-evident and post-quantum-signed, so anyone can verify it. It is proof of provenance and verification, not proof of truth.
An AI model produces its reasoning off-chain: the ordered steps that lead to a conclusion.
ModelThe Reasoning Verification Framework runs deterministic checks and adversarial cross-examiners, then reaches a verdict.
RVFThe verdict and a hash of the exact reasoning are signed with ML-DSA65 and anchored in a block, tamper-evident for good.
Witness ChainA concept transparency ledger for a Philippine city: budgets, disbursements, contracts, permits and projects, each record hash-verifiable and sealed. Try the live tamper test. Prototype with synthetic data.
Adversaries are already recording today’s encrypted data to unlock it once quantum computers mature. In 2024, NIST finalized the post-quantum standards, and governments are targeting migration by 2030-2035. The largest chains face a multi-year retrofit of cryptography they were never built for, COGNITUM was quantum-resistant from its very first block.
Not a patch on old cryptography, built on the 2024 NIST standards from genesis.
Every transaction, block, and validator vote is signed with ML-DSA65, the address is the post-quantum public key.
FIPS 204 · ML-DSANode-to-node sessions are encrypted with ML-KEM768 + AES-256-GCM, so peer traffic stays private against quantum attacks.
FIPS 203 · ML-KEMA conservative SLH-DSA fallback on a different math family - implemented and tested, activation audit-gated - ready to stand if lattices are ever weakened.
FIPS 205 · SLH-DSA · audit-gatedLive testnet, honest about what is operational vs. roadmap, multi-round internal audits, published limitations.

What we're building next on the quantum-safe rail. Funded roadmap, not yet live, shown here so you can see where COGNITUM is headed.
Tokenize gold, real estate and bonds on a quantum-safe rail, each token backed 1:1 and redeemable.
Mint, own and trade non-fungible tokens and asset certificates, secured by post-quantum signatures.
Trustless HTLC swaps to other chains, no custodian in the middle. Testnet demo today, production next.
Additional EVM and non-EVM chains beyond the current wCOGN bridge, one liquid, quantum-safe hub.
On the roadmap and not a promise of a live feature. Timing depends on the audit and mainnet milestones on the roadmap.
An honest, fact-checkable look, including the chains that got there before us.
| Chain | Signature | Quantum-resistant? |
|---|---|---|
| Bitcoin | ECDSA | Planning |
| Ethereum | ECDSA | Planning |
| Solana | Ed25519 + opt-in Winternitz vault | Partial · opt-in, storage only |
| Algorand | Ed25519 + Falcon state proofs | Partial · since 2022 |
| QRL | XMSS · stateful, pre-FIPS | Yes · since 2018 |
| COGNITUM | ML-DSA65 · FIPS 204 | Yes · testnet |
We are not the first quantum-resistant chain, QRL has signed every transaction with hash-based XMSS since 2018, and Algorand has run Falcon state proofs since 2022 (its consensus layer is still Ed25519). Solana offers an opt-in hash-based vault, but for storage only, it needs a fresh address per transaction and its everyday signatures are still Ed25519. What is different here: COGNITUM is built on the finalized 2024 NIST standards (FIPS 204 ML-DSA-65, FIPS 203 ML-KEM-768) for account-level signatures, by default on every transaction, stateless, and integer-only, avoiding the timing side-channel surface of Falcon's floating-point math and the key-reuse hazard of stateful XMSS. COGNITUM is a testnet: our cryptography is production-grade, our network is not yet decentralized.

No hype. What is true and checkable today, and what is still ahead, stated plainly.
