The Architect’s Challenge
If you work as an architect, you know the risk: design concepts shared with clients or contractors get replicated by cheaper firms. When it comes to regulatory submission proof, the stakes are real - without independent evidence, disputes become your word against theirs.
Your Workflow with TimeProof
Timestamp the exact filing package before or at submission so later deadline, signoff, or integrity questions point back to a public record. Best used at filing, submission, or final pre-submission signoff. Common files in this workflow include submission packets, signed forms, and supporting exhibits. Typical reviewers or counterparties include regulators, auditors, and compliance leads.
1. Design.
2. Export plans.
3. Timestamp each phase.
4. Then share.
The timestamp step fits into that workflow without changing the tools you already use.
The timestamping step itself takes under 10 seconds. No blockchain expertise required.
Why Regulatory Submission Proof Matters
Prove when regulatory documents were finalized for audit defense. A blockchain timestamp timestamps regulatory documents to prove timely preparation, creating evidence that is:
- Independent — stored on the public Polygon blockchain, not controlled by TimeProof or any party
- Permanent — cannot be altered, deleted, or disputed after recording
- Verifiable — anyone can check the timestamp on Polygonscan without an account
- Cryptographic — the SHA-256 hash changes if even one byte of the file changes
How Timestamping Works
When an architect timestamps a file for regulatory submission proof, TimeProof uses client-side file hashing (SHA-256). That 64-character value is the unique fingerprint for the exact version you selected, and if even one byte changes, the hash changes too. That fingerprint proves the exact version you created before it is shared or disputed. Your file never leaves your device.
TimeProof proves file existence by anchoring file hashes to the Polygon blockchain. The blockchain records the hash, timestamp, and transaction ID permanently, so anyone can verify the record independently on Polygonscan without relying on screenshots, local metadata, or someone else’s database.
For architects, interior designers, and urban planners, that means prove when regulatory documents were finalized for audit defense without relying on editable logs or file-system dates.
What You Receive
Every TimeProof timestamp for regulatory submission proof includes:
- PDF certificate - a readable proof document you can keep with the project file, send to a client, or hand to counsel if the timeline is later challenged.
- Polygonscan link - direct public verification so a reviewer can confirm the blockchain record independently.
Verified instant timestamps also include: 3. Verified identity badge - the certificate shows the timestamp was created by a verified account, which is useful when timing and submitter identity both matter to the dispute or review.
With the Legal-Grade upgrade, you also receive the core evidence-package components documented by TimeProof: PDF, JSON, JWS identity attestation, and a ZIP bundle.
- Courtroom-Ready PDF - a presentation-ready evidence certificate when regulatory submission proof needs more than a standard project record.
- JSON Metadata - machine-readable timestamp data for technical teams, audit trails, or structured evidence review.
- Identity Attestation (JWS) - a signed proof that ties the timestamp to a verified identity and can be verified through /.well-known/jwks.json.
- Complete Evidence ZIP - one bundle containing the Courtroom-Ready PDF, JSON Metadata, Identity Attestation (JWS), and supporting proof materials such as the Merkle proof, verification guide, and checksums, so the record is ready for formal review.
Real Scenario
Imagine you are an architect. A team submits a regulated filing, then later needs independent proof that the exact submission packet existed before the stated deadline or audit challenge. The files at issue are often submission packets, signed forms, and supporting exhibits. Typical counterparties include regulators, auditors, and compliance leads.
A regulator questions the filing date, a portal record is incomplete, or an audit alleges the submission packet was assembled after the deadline. The timestamp anchors the exact filing package to a public time so the timing record does not depend only on the submission portal or internal logs.
With TimeProof, the dispute is resolved by independent proof instead of by screenshots, local metadata, or conflicting memories.

Cost for Architect
TimeProof uses one unified credit balance, so architects, interior designers, and urban planners can create routine proof early and only step up to verified features when the situation calls for it.
- Scheduled timestamps: 1 credit per file - available to everyone, with proof available within 6 hours.
- Instant timestamps: 2 credits per file - available to verified subscribers, anchored in about 2 seconds.
- Legal-Grade: Starter and Pro: 50 credits up to 25 files, then +2/file. Business: 25 credits up to 25 files, then +1/file. Enterprise: included.
One-time packs start at $15 for 100 credits. Verified monthly plans start at $19/month and include identity verification for instant timestamps and Legal-Grade.
That lets you use scheduled timestamps for everyday regulatory submission proof records and reserve verified instant or Legal-Grade proof for the files most likely to be challenged.
Most architects, interior designers, and urban planners need routine, repeatable protection rather than an enterprise rollout. TimeProof is priced for routine use through packs and verified monthly plans, so you can build evidence as you work instead of only after a dispute starts.
Privacy
Your files related to this workflow never leaves your computer. TimeProof uses client-side file hashing (SHA-256). Only the 64-character hash string is sent for anchoring. Because SHA-256 is one-way, it is not possible to reconstruct the original file from the hash. That lets architects, interior designers, and urban planners protect work related to regulatory submission proof without exposing the original file, unpublished draft, or client material.
