Begin with limited baseline documentation, then adopt higher evidentiary rigor as risk exposure and dispute likelihood increase.
Every access profile produces permanent, tamper-evident proof records anchored on public blockchains. ProofLedger is designed for pre-loss documentation, compliance checkpoints, and evidence that must survive hostile audit or dispute. Higher access profiles reflect increased exposure, stricter procedural expectations, and optional escalation-grade evidence anchoring.

Operational purpose
- Pre-loss capture: record what existed before incentives change (claim, dispute, audit)
- Tamper-evident procedure: any change to the underlying record breaks verification (hash + public anchor)
- Independent verification: third parties can validate timestamps without needing ProofLedger access
- Artifact vs authority: certificates are derived artifacts; the public verification record is canonical
- Non-custodial posture: ProofLedger does not store your original files—only one-way cryptographic hashes

Certificates are human-readable representations only; cryptographic verification and public blockchain anchors remain the authoritative record.
Add-ons & Bitcoin Anchoring
These options apply when higher evidentiary rigor or independent Bitcoin anchoring is required beyond baseline documentation. Use add-ons when you need one-off Bitcoin-anchored evidence or expanded submission capacity beyond baseline access.
- Baseline / Standard access: from $7.99 per proof
- Elevated access: from $5.99 per proof
- Formal legal access: from $3.99 per proof
- Includes Polygon + Bitcoin anchoring for the same file
- Paid only when you enable “Add Bitcoin anchoring” for a proof
- Batch-anchored for efficient, auditable timestamps
Logged-in subscribers see additional discounted bundle options.
- Pay only when you need extra proofs
- Public verification links for every proof
- Subscribers unlock lower per-proof pricing and larger volume bundles
Active subscribers access lower per-proof pricing (as low as $0.10 per proof) and higher-capacity bundles.
Pre-loss temporal authority documentation is the practice of recording evidence at the moment of creation, cryptographically fixing its state in time before disputes, incentives, or claims exist. These systems establish when a record existed and what state it was in using repeatable, tamper-evident procedures that allow independent verification without reliance on the recording system itself.
ProofLedger is an implementation of this approach, designed for high-liability environments where contemporaneous, pre-loss records must remain verifiable long after they are created.
