Introducing QuantumAI Blockchain (QBC): post-quantum crypto + on-chain AI, in Rust

BlockArtica — Sun, 24 May 2026 13:39:49 +0000

A new layer-1 that puts NIST-level-5 post-quantum signatures, an on-chain
neural network, and an EVM-compatible VM behind a Substrate-based chain.
Here's what's actually inside — and where it sits today.

The pitch in one paragraph

QuantumAI Blockchain (QBC) is a Substrate-based layer-1 that combines three
things most chains treat as separate problems:

Post-quantum cryptography — CRYSTALS-Dilithium5 signatures (NIST level 5) and ML-KEM-768 for peer transport. Built for the world where Shor's algorithm runs on actual hardware.
An on-chain neural network — "Aether Mind," a 558M-parameter Rust transformer whose reasoning passes through 10 smart-contract gates ("the Sephirot") before any action is sealed on chain. Every block since genesis carries a Proof-of-Thought attestation hash.
EVM compatibility plus quantum opcodes — the Quantum Virtual Machine (QVM) ships 155 EVM opcodes plus 10 quantum and 2 AI opcodes, so existing Solidity contracts deploy unchanged and can opt into the extensions.

Tagline: "The blockchain that learns. Evolves. Becomes."

If that sounds like it's trying to be three projects at once — it is.
The interesting question is how the pieces fit.

The post-quantum bit

The consensus is called Proof-of-SUSY-Alignment: 8-qubit VQE quantum
circuits running on a Substrate runtime, with per-block difficulty
adjustment and 3.3-second block times. Chain ID 3303.

Signatures are CRYSTALS-Dilithium5 — one of the NIST-finalist post-quantum
schemes, level 5 (strongest). Peer transport uses ML-KEM-768 (formerly
Kyber). These are not bolted on after the fact; they're the default
signature path. The currency model is a φ-emission schedule: 3.3B max
supply, phi-halving over 33 years.

If you've watched the NIST PQC standardization process and wondered when
a production chain would actually ship Dilithium-5 as the default, this
is one of the answers.

Aether Mind

The AI side is more ambitious — and is where the project's most novel
claim lives. Aether Mind is a pure-Rust system built from Candle
(transformers), HNSW (a vector index), and Ollama (RAG). The current
release, v6.2, is 558M parameters with a 14-head "Sephirot split"
attention layout and a 256-token context. Reported throughput: 623
tokens/s on a 3080 Ti.

Published benchmarks for the v5.2-LoRA training run:

Benchmark	Score	vs. baseline
MMLU (5-shot)	69.4%	—
ARC-Challenge	53.9%	+9.7pp
ARC-Challenge (norm.)	57.0%	+10.0pp
ARC-Easy	81.9%	+8.5pp
TruthfulQA-MC2	57.1%	+5.5pp
HellaSwag	77.7%	—

The genuinely-novel piece is the Sephirot gating system. Ten on-chain
smart contracts gate every reasoning cycle. Three of them are
load-bearing:

Keter verifies a goal exists.
Gevurah validates safety constraints and can veto.
Malkuth only seals the action if Keter and Gevurah both pass.

Beyond that, three pairs of Sephirot are kept in golden-ratio
(φ = 1.618...) balance by an on-chain SUSYEngine that redistributes
"cognitive mass" between partners when a pair drifts past threshold.
The chain itself enforces the AI's structural balance, every block.

Model weights for every release are on Hugging Face.

QVM and the bridges

The QVM is EVM-compatible (155 standard opcodes) with 10 quantum opcodes
and 2 AI opcodes layered on top. An institutional-compliance engine
handles KYC/AML/sanctions checks on chain.

Wrapped-QBC tokens already exist on eight chains: Ethereum, Solana,
Polygon, Avalanche, BNB, Arbitrum, Optimism, and Base. The Ethereum
contract: 0xB7c8783dDfb7f72b2C27AFBDFFD2B0206046Fa67.

Where it sits today

Being honest about state matters more than marketing copy:

3 validators currently running
Aether Mind v6.2 trained and published; weights on Hugging Face
Wrapped QBC tokens deployed on 8 chains
Presale: opening soon, 90-day countdown live
Public RPC is intermittent — full mainnet is the next milestone, not the current state

So: the tech is real, the model is real, the bridges are real. The
fully-live chain is the milestone ahead.

Takeaways

QBC is a Substrate layer-1 with NIST-level-5 post-quantum signatures (Dilithium5) and post-quantum peer transport (ML-KEM-768) as defaults, not opt-ins.
"Aether Mind" is a 558M-param Rust transformer (Candle + HNSW + Ollama) whose every reasoning cycle clears 10 on-chain smart-contract gates before any action is sealed.
A SUSYEngine enforces golden-ratio balance between paired Sephirot contracts — the chain literally constrains the AI's structural symmetry per block.
QVM is EVM-compatible plus 10 quantum and 2 AI opcodes; wrapped QBC already lives on 8 chains.
Honest current state: 3 validators, Aether Mind v6.2 published, public RPC intermittent — bigger milestones (full mainnet, presale open) ahead.
