A claims manager gets a call on Tuesday morning. Storm damage claim from the weekend. The insured has photos of their roof "before the hail." The timestamps show Sunday morning — after the storm hit Saturday night. The adjuster spots it immediately.
This happens daily. Contractors document existing conditions. Homeowners photograph valuables. Adjusters capture loss scenes. But digital timestamps can be altered. Metadata can be stripped. Cloud uploads reset dates. When disputed, there's no way to prove when evidence actually existed.
ProofLedger solves this with blockchain-anchored timestamps. The moment you capture evidence, it generates an immutable record on both Polygon and Bitcoin blockchains. The file stays on your device. Only the SHA-256 hash gets anchored.
Here's the workflow: An adjuster photographs a pre-loss condition. ProofLedger instantly creates a Polygon blockchain entry with the exact timestamp. Within 24 hours, it bundles that hash into Bitcoin via merkle proof for permanent verification. The blockchain record exists independently of the file itself.
Courts can authenticate this under FRE 901(b)(9) — evidence from "a process or system that produces an accurate result." The blockchain process is mathematically verifiable. The timestamp cannot be backdated. The hash proves the evidence existed at that specific moment.
For claims professionals, this creates bulletproof chain of custody. Document a roof inspection on Friday. Storm hits Saturday. Your blockchain anchor proves the evidence predates the loss. No disputes about when photos were taken. No questions about file manipulation.
The dual-chain approach provides both speed and permanence. Polygon delivers instant verification for immediate needs. Bitcoin provides the gold standard for long-term disputes. High-value claims with multi-year discovery windows need this level of certainty.
Consider the alternative: You're three years into litigation. The opposing counsel challenges your evidence timeline. Without blockchain anchoring, you're explaining file metadata and cloud storage timestamps to a jury. With ProofLedger, you point to an immutable blockchain record.
The evidence either existed before the loss or it didn't. Blockchain makes that determination mathematically certain. No interpretation required. No technical explanations needed. The timestamp is what it is.
Chain of custody has never been simpler. Capture evidence. Anchor it. Present the proof when needed. The blockchain does the rest.
