Blockchain-Based Secure File Storage
Tamper-evident file storage combining encryption, decentralised infrastructure, and on-chain verification for documents that must be provably authentic.
Some files must be more than stored — they must be provable: contracts, certificates, compliance records, intellectual property, audit evidence. ZebIQ builds storage systems that combine strong encryption with blockchain anchoring, so you can demonstrate cryptographically that a document existed at a point in time and has not been altered since.
The architecture is pragmatic. Files are encrypted client-side and stored on decentralised networks (IPFS with pinning services, or hybrid models pairing cloud object storage with decentralised redundancy). A cryptographic hash of each file — never the file itself — is anchored to a public blockchain, creating an immutable, independently verifiable timestamp and integrity proof. Access control, versioning, and sharing flow through a conventional, user-friendly interface; the cryptography works invisibly underneath.
This model fits wherever trust between parties is expensive: multi-vendor event contracts, certification programmes issuing verifiable credentials, legal and compliance archives, and creative agencies protecting proof of authorship. Verification is open — any third party can confirm a document's integrity without trusting us or you.
What's included
Client-Side Encryption
Files encrypted before they leave your device with keys you control — storage providers never see plaintext.
On-Chain Integrity Anchoring
Document hashes committed to a public blockchain, creating tamper-evident, independently verifiable proof of existence and integrity.
Decentralised Redundancy
IPFS-based or hybrid storage removing single-provider failure and censorship risk for critical archives.
Verifiable Sharing
Recipients and third parties can verify a file's authenticity and timestamp without any account or trust relationship.
Versioning & Audit Trail
Every revision hashed and anchored, producing a complete, provable document history.
Familiar UX
Upload, organise, and share through a clean web interface — the blockchain layer requires zero user expertise.
How it works
A clear, numbered path from kickoff to live operation — so you always know what happens next.
Use-Case & Trust Analysis
We identify which documents genuinely benefit from on-chain proof and define retention, access, and verification requirements.
Architecture Design
Storage topology, encryption and key-management model, and chain selection balanced for cost, longevity, and verification needs.
Build & Integrate
Platform implementation with API hooks into your existing document workflows and systems.
Verify & Train
End-to-end verification testing with your stakeholders and training on the proof workflow for non-technical users.
Where it shines
Contracts & Vendor Agreements
Multi-party event and business contracts stored with independently verifiable signing timestamps and integrity proofs.
Certificates & Credentials
Training and participation certificates that employers and institutions can verify in seconds without contacting the issuer.
IP & Compliance Archives
Creative work, designs, and audit evidence with provable existence dates for disputes and regulatory review.

Frequently asked
No — that would be impractical and would expose your data. Files live encrypted in decentralised or hybrid storage; only a cryptographic fingerprint (hash) goes on-chain. The hash proves integrity and timestamp but reveals nothing about the content.
Cloud storage protects against loss; it cannot prove a file was not altered, by you or anyone else. Blockchain anchoring adds independent, third-party-verifiable proof of existence and integrity — which matters in disputes, audits, and credential verification where your own word is not evidence.
Key management is designed into every deployment: options include enterprise key escrow, multi-party recovery schemes, and HSM-backed custody. We agree the recovery model with you up front, because with client-side encryption, lost keys with no recovery path mean unrecoverable data — by design.
