Maximum coherence through complex simplicity

Validian is a public utility for digital truth. It's a decentralized protocol that creates a permanent, verifiable record for any digital file. Using open cryptography and decentralized storage, Validian anchors media to the blockchain, creating a universal and permissionless standard for authenticity.

Validian Protocol

Media Verification Flow

1. Capture / Select
Mobile media, caption, location preference, device time
2. Local Context
Semantic analysis + encrypted graph — inferred signals, not proof
3. Server Prepare
MIME sniff, size cap, SHA-256, coords + EXIF sanity
4. Receipt Payload
Author pubkey, media hash, challenge nonce, capture method, platform
5. User Signatures
Receipt hash signature + capture-binding signature, optional platform attestation
6. Commit
Verify signatures, consume challenge, moderation gate
AI
7. Evidence + AI Signals
IP/EXIF/time-skew flags, AI forensic EXIF worker, trust score
8. Public / Offline Verify
Receipt hash, signature, capture binding, media hash, optional Merkle/chain checks

Storage & Publication

IPFS
Stores accepted media and signed receipt JSON
Postgres
Post, canonical capture, evidence receipts and records
Async Publication
Nostr reference event — not required for base verification

Optional Extensions

On-Chain Anchor
Merkle root batches anchored to Polygon — no full record on-chain
Collectible
Claim verified media as an ownable digital object
C2PA Manifest
Non-blocking mobile manifest — does not upgrade proof

Signature-based verification chain from capture to public, offline-capable proof — with optional anchoring and tokenization layered on top

From Verification to Value

Validian separates truth from value. First, the protocol provides a permanent guarantee of authenticity for any file. From there, creators have the freedom to turn verified assets into unique, ownable digital objects through optional NFT tokenization. This allows anyone to prove ownership and participate in the digital economy with confidence.

The Protocol: Open and Secure by Design

Validian is built as an open verification protocol for digital media. Its purpose is to make provenance portable: any verifier should be able to inspect an asset, recompute its hashes, validate signatures, check proof artifacts, and understand exactly which claims are proven, attested, inferred, or still unverified.

Cryptographic & AI Security

SHA-256 Hashing
Creates deterministic fingerprints for media, receipts, metadata, and proof bundles.
Schnorr / ECDSA-Compatible Signature Layer
Binds creators, devices, servers, and verification actors to the exact asset record.
Merkle Trees
Compress many verified receipts into efficient inclusion proofs for batch anchoring.
Zero-Knowledge Proofs
Enables private verification of selected capture, device, or integrity claims without exposing sensitive source data.
Hardware Key Protection
Uses secure enclaves, HSMs, or managed key custody for production signing authority.
AI Verification Signals
Adds forensic, semantic, classification, and anomaly-detection signals as bounded evidence, not unchecked truth.

Decentralized Infrastructure

Content-Addressed Storage
Stores media and proof artifacts by hash so records can be independently retrieved and verified.
Multi-Layer Anchoring
Anchors proof roots across blockchain, data-availability, and transparency-log infrastructure.
Distributed Verification Nodes
Allows independent verifiers, edge services, and partner systems to validate receipts and publish attestations.
High-Availability Proof Access
Replicates proof bundles, receipts, and public verifier data across resilient infrastructure.
Optional Tokenization
Lets verified assets become ownable collectibles, NFTs, licenses, or marketplace objects without making tokenization mandatory for proof.
