Calibrant, chainNode's automated discovery agent, finds every networked asset on your facility and permanently records its configuration on the Polygon blockchain. Tamper-proof. Publicly verifiable. Always on.
The problem
These are the most common complaints recorded in manufacturing facility focus groups, documented year over year across industries.
Dozens of networked devices — PLCs, HMIs, sensors, cameras, controllers — with no unified record of what state they're in or when they changed.
"Wisdom left with people and lost records in the crash." When operators retire, their knowledge about every device configuration leaves with them.
A line goes down. A firmware change caused it. But when was it made, and by whom? Without immutable records, there's no answer — just someone's memory.
Verbal handoffs break. Radios fail. Notes get lost. Every shift supervisor needs to see the same verified truth about what happened on the previous shift.
SOC 2, ISO 27001, FDA 21 CFR Part 11 require documented configuration control. Building audit trails manually takes days — and they're still disputed.
Unauthorized firmware updates on PLCs and controllers go undetected. By the time anyone notices, the configuration history is gone.
How it works
chainNode runs entirely inside your network. Nothing leaves your facility except a cryptographic fingerprint.
Run one command on any machine already inside your network. No firewall changes. No IT tickets.
Calibrant scans your subnet and surfaces every networked device — PLCs, HMIs, sensors, cameras, HVAC controllers — within minutes. Default scan cadence: every hour, tunable down to 5 minutes.
Each asset's configuration is written to the Polygon blockchain with a timestamp, block number, and transaction hash. Permanently.
Any configuration change — authorized or not — triggers an immediate verified alert. The change history is preserved forever.
Hourly vs. weekly
Calibrant's fingerprint-based discovery is lightweight enough to run continuously — catching unauthorized changes in minutes, not days. Tune down to 5-minute intervals for OT and critical infrastructure.
Sources: vendor documentation and default deployment templates. chainNode's hourly default is possible because scans capture configuration fingerprints, not heavy credentialed deep discovery.
Features
chainNode is purpose-built for industrial environments. No enterprise bloat. No implementation consultants. No months-long onboarding.
Real-time dashboard
Your entire facility's networked infrastructure — named, classified, and blockchain-verified — visible in a single dashboard from the moment chainNode is installed.
Immutable change history
Every configuration change — firmware updates, IP changes, risk reclassifications — is written to the blockchain with an exact timestamp and transaction hash. Nothing can be altered after the fact.
Industry vertical
50,000 connected water performance systems. 90 billion data points. Every configuration change, every anomaly, every compliance event — permanently anchored on blockchain. When regulators ask what your system was doing at a specific moment, the answer is on Polygonscan.
Continuous monitoring of cooling towers, boilers, and membrane systems — classified automatically and tracked on every scan.
Configuration drift detection before equipment failure — parameter baselines flag deviations the moment they happen.
EPA, OSHA, and FDA compliance reports with blockchain attestation — every record independently verifiable on Polygonscan.
Industry vertical
NERC CIP requires utilities to maintain tamper-proof records of every change to critical infrastructure systems. chainNode monitors every substation controller, every SCADA server, every smart meter — and anchors every configuration change permanently to blockchain.
Tamper-proof records of every configuration change to bulk electric system cyber assets — independently verifiable on Polygonscan.
Continuous monitoring of distribution automation and smart metering — classified automatically and tracked on every scan.
Every change to pipeline SCADA controllers and gas pressure regulators detected and recorded for TSA pipeline security directives.
Industry vertical
NRC 10 CFR 50 requires complete, unalterable records for nuclear facility computer systems. chainNode creates a permanent blockchain record of every configuration state — before and after every change.
Permanent blockchain state for reactor protection, safety parameter display, and emergency core cooling systems — before and after every change.
Complete, unalterable records for nuclear facility computer systems, satisfying 10 CFR Part 50 record-keeping requirements.
Every configuration record is independently verifiable on a public blockchain — no chainNode account required to confirm.
Industry vertical
SOC 2, FedRAMP, and CMMC audits require evidence that security controls were in place at specific points in time. chainNode's blockchain-anchored configuration records are the evidence auditors trust.
Vulnerability scanners, SIEM servers, privileged access workstations, and HSMs monitored continuously and anchored on-chain.
Point-in-time, blockchain-anchored configuration records for SOC 2 Type II, FedRAMP, CMMC, and NIST SP 800-53.
Findings and remediation states anchored permanently — provable evidence of when a control was in place.
Industry vertical
Oracle, SAP, and Microsoft license audits can generate millions in unexpected costs. chainNode tracks every software deployment against license entitlements — permanently on blockchain.
Every software deployment tracked against its license entitlement, continuously and automatically.
Purchase documents hashed and anchored on blockchain — an unalterable record of what you bought and deployed.
Deployments that exceed entitlements are flagged in red — compliance risk surfaced before it becomes a bill.
The blockchain guarantee
They live on the Polygon blockchain — a decentralized public network maintained by thousands of independent computers. No single company owns it. No single company controls it.
The Polygon network has operated without interruption since 2015. It will continue running whether chainNode exists or not.
Every record written to the blockchain is permanent. It cannot be edited, deleted, or disputed — by anyone, including chainNode.
Anyone can go to PolygonScan.com and verify any asset record independently. No chainNode account. No login. No access required.
