Real-Time Blockchain Resilience
QABRE
Defend your blockchain before the attack lands.
QABRE is a real-time resilience framework that scores compromise risk across your validators, wallets and transactions, and acts automatically, defending against the quantum and AI threat together.
Patent-pending · UK GB2613808.1
Two threats. One blind spot.
Quantum computing threatens the cryptography every blockchain signature depends on, while AI is industrialising attacks at machine speed. Most defences watch one signal, and react only after the damage.
Exposed by design
Public keys are exposed on-chain, permanently or in the window between broadcast and confirmation. A capable quantum computer could derive private keys from them.
Attacks at machine speed
Automated agents probe, manipulate and exploit blockchain systems faster than human-paced tooling can answer.
Defences that only report
Scanners measure exposure. Dashboards score readiness. Neither acts. Consensus penalties arrive only after a bad block is already signed.
How QABRE works
Acquire
Lightweight agents read signals across cryptographic exposure, randomness quality, network topology, automated-attack pressure and the physical state of signing hardware. Your signing flows are unchanged.
Score
A scoring engine combines those signals into one live resilience score for each validator, wallet or transaction. Runs as a hosted service or an on-premises appliance.
Act
When risk crosses your threshold, QABRE enforces automatically through connectors to systems you already run: adjusting a validator's role in consensus, constraining signing, escalating a risky settlement, or prompting key rotation.
Attest
Optionally record resilience states on-chain, so protocols, counterparties and insurers can verify your posture without taking your word for it.

Watch how QABRE worksProtecting the part that matters most
A blockchain is only as trustworthy as the validators that vote on every block. A validator with tampered hardware or a quantum-exposed key endangers the whole network.
Today
Penalise the validator after it has signed a bad block.
With QABRE
Score its hardware and key exposure continuously, and remove it from consensus before it can sign. The malicious block is never created.
Built for the people who carry the risk
Staking operators
Protect validators against compromise and give institutional clients a credible quantum and AI readiness answer.
Custodians
Exposure-aware signing controls and emergency key rotation, with auditable evidence for your clients.
Exchanges
An operational, regulator-facing defence across settlement and signing.
Security and hardware teams
A live enforcement layer that complements your migration and inventory tooling instead of duplicating it.
Where QABRE stands today
We would rather be precise than impressive.
Validated in simulation
Tested in controlled simulation, including against adversaries actively optimising to evade the score. The combined measure outperformed any single signal.
A limit we state openly
No scoring system detects a sufficiently quiet attack. QABRE raises the minimum loudness an attack must have and catches detectable attacks earlier. It does not claim to stop every attacker.
Real-world validation is next
A testnet deployment with real hardware telemetry and an independent red-team assessment is the next stage. Until then QABRE is an evidenced framework moving toward product.
The full picture: the problem, the framework, the benefits, and an honest account of the evidence.

We are selecting a small number of design partners for testnet validation and early deployment. If you run validators, custody or an exchange, we would like to hear what you are trying to protect.
