Six layers of proof.
One unified platform.
TimeProof starts with a live proof foundation and extends upward carefully. This page separates what exists in V1 from what remains roadmap-only.
The TimeProof Stack
Each layer builds on the one below it. Together, they create the most comprehensive digital proof architecture in the current TimeProof direction, without blurring live V1 capability and later-phase work.
Application Layer
Layer 6TimeProof App
LiveUser dashboard, file upload, certificate management, organization tools
Verification Portal
LivePublic verification — anyone can verify a timestamp, no account needed
Free Browser Tools
LiveSHA-256 hasher, EXIF viewer, file comparator — all client-side
Proof Layer
Layer 5Instant Timestamps
LiveImmediate anchoring for verified subscribers under the live Credits 2.0 model.
Scheduled Timestamps
LiveBatched anchoring with the lowest live credit cost.
Legal-Grade Evidence
Live7-file courtroom-ready evidence bundle with JWS identity attestation.
Identity Layer
Layer 4JWS Attestation
LiveJSON Web Signature links your verified identity to each timestamp cryptographically.
JWKS Verification
LiveThird parties verify identity via /.well-known/jwks.json — no TimeProof contact needed.
SIWE Authentication
LiveSign-In with Ethereum — wallet-first, no passwords, no email-only accounts.
Ownership Layer
Layer 3Parent Prints (COP)
RoadmapFuture-phase ownership artifact for proving origin inside COP-aware workflows.
Child Prints
RoadmapFuture-phase lineage records for derivatives, licensing, and permissions.
Visual Fingerprints
RoadmapFuture-phase presentation layer for ownership and provenance signals.
Authenticity And Provenance Research
Layer 2Authenticity Analysis
RoadmapFuture-phase research into stronger authenticity and manipulation checks.
Content Provenance
RoadmapFuture-phase chain-of-authenticity workflows for recorded assets.
Advanced Compute Integrations
Later PhaseLonger-term exploration for privacy-preserving authenticity services.
Blockchain Infrastructure
Layer 1Polygon PoS
LiveFast finality, low cost, production-grade security. Current network.
Gasless Architecture
LiveTimeProof sponsors all gas fees. Users never touch network costs.
Smart Contract (TimeProofAnchor)
LiveOn-chain anchoring of SHA-256 hashes and Merkle roots.
Built on proven cryptography.
Not proprietary black boxes. TimeProof uses open, auditable, industry-standard cryptographic primitives — the same ones that secure the internet and the blockchain.
SHA-256 Hashing
NIST FIPS 180-4Like a fingerprint — unique to every file. Change one byte and the hash is completely different.
Every file uploaded to TimeProof is hashed client-side before anything leaves your device. We never see your file.
Merkle Trees
Used in Bitcoin, Ethereum, GitLike a table of contents that proves every chapter is exactly where it should be. Tamper with one page and the whole tree breaks.
Scheduled Timestamps batch multiple files into a single Merkle root, anchored in one blockchain transaction.
ECDSA Signatures
RFC 6979 / secp256k1Like a wax seal on a letter — only the sender could have made it, and breaking the seal proves tampering.
Every blockchain transaction is cryptographically signed. Every LG package includes a verifiable JWS signature.
JSON Web Signatures (JWS)
RFC 7515 / RFC 7517Like a notarized signature you can verify from anywhere in the world, instantly, without calling the notary.
Legal-Grade packages include a JWS identity attestation. Verifiers check the signature against our public JWKS endpoint.
Gasless by design.
Every blockchain transaction costs "gas" — network fees paid to validators. Most blockchain products pass these fees to users, requiring them to buy cryptocurrency and manage wallets.
TimeProof handles all of it. When you timestamp a file, we sponsor the gas transaction behind the scenes. You never need crypto, never see a gas fee, never interact with a blockchain directly. It's like free shipping — the product costs what it costs, and we handle the delivery.
Courtroom-ready evidence.
The Legal-Grade package is the difference between telling a judge "I have proof" and handing the judge a sealed evidence binder with everything they need to verify it themselves.
7-File Legal-Grade Evidence Package
certificate.pdf Human-readable certificate with all proof details, formatted for courts and arbitration.
certificate.json Machine-readable certificate data. Programmatically verifiable by any system.
merkle_proof.json Cryptographic proof showing exactly how your file connects to the blockchain anchor.
identity_attestation.jws JSON Web Signature linking your verified identity to this timestamp. Self-proving.
identity_readme.json Instructions for verifying the JWS attestation against our JWKS endpoint.
verification_guide.txt Step-by-step instructions a lawyer or judge can follow to verify everything independently.
CHECKSUMS.sha256 SHA-256 checksums for every file in the package — proves the package itself hasn't been tampered with.

This technical overview stays intentionally high level. The docs cover the product reference material, and the whitepaper adds the product thesis, boundaries, and rollout framing without exposing sensitive implementation detail.
