Overview

RKP-2 (Off-Chain) is ROOTKey’s high-performance data processing protocol. Data is processed and stored off-chain through ROOTKey’s infrastructure, while a cryptographic proof - a SHA-256 hash of the payload - is anchored asynchronously to the Polygon blockchain. The result is near real-time API response times with blockchain-backed integrity guarantees. Verification relies on hash comparison between the original data and the on-chain proof, without requiring the full payload to be written to the chain. This protocol is designed for high-frequency write workloads, IoT and sensor data, operational telemetry, and any scenario where throughput and cost efficiency are primary constraints, but cryptographic integrity remains non-negotiable.

​
Architecture Overview

The API returns a response immediately after off-chain processing completes. Blockchain anchoring occurs asynchronously within a defined window. This design decouples response latency from block confirmation time while preserving the integrity guarantee. Each anchored record includes:
  • SHA-256 hash of the data payload
  • Anchor timestamp (block timestamp)
  • Asset and operation identifiers
Integrity verification is performed by re-hashing the stored data and comparing against the on-chain record - a process that can be independently executed by any party with access to the data and blockchain.

Validation Capabilities

Validation TypeSupported
Hash-based integrity verificationYes
On-chain proof of existenceYes
On-chain proof of integrity (hash match)Yes
Independent verification by third partiesYes (requires access to original data + blockchain)
Full payload retrieval from blockchainNo (off-chain storage)
GDPR-compatible erasure of off-chain dataYes
Verification requires access to the original data asset and the on-chain hash. Any party holding the data can independently confirm its integrity by recomputing the hash and comparing it to the on-chain record.

​
Strengths

  • High throughput - designed for large-scale, high-frequency write workloads
  • Near real-time response - API latency is decoupled from blockchain confirmation
  • Lower cost per operation - off-chain processing reduces gas fee exposure per request
  • GDPR erasure compatibility - off-chain data can be deleted; the on-chain proof remains as evidence of prior existence without containing personal data
  • Scalable to IoT scale - supports high-volume sensor and device data pipelines
  • Same integrity guarantees - cryptographic proof anchored on-chain regardless of throughput

​
Weaknesses

  • Partial on-chain footprint - only the proof is on-chain; full record recovery requires ROOTKey off-chain storage or client-side copy
  • Verification requires original data - third-party verification is not self-contained from the blockchain alone
  • Storage dependency - integrity of the verification chain depends on the availability of the off-chain record

​
Typical Use Cases

Industrial IoT and Sensor Networks

High-frequency telemetry from sensors, PLCs, and connected devices - integrity-protected at volume without per-record blockchain costs.

Operational Telemetry and Monitoring

Real-time operational logs, system events, and monitoring streams requiring tamper-evident archiving at scale.

Healthcare Data Pipelines

Patient records, diagnostic data, and clinical trial logs where volume is high, integrity is mandatory, and GDPR compliance requires erasure capability.

Energy and Utility Metering

Smart meter readings, grid event logs, and consumption records for regulatory reporting and dispute resolution.

Logistics and Fleet Tracking

GPS events, custody transfers, and condition monitoring data for perishable or high-value cargo.

Bulk Document Archiving

Large-volume document archiving for regulated industries where every record requires integrity evidence but full on-chain costs are prohibitive.
