What is Arkivia

A cloud archive built on blockchain.

Arkivia gives your company a secure cloud storage where every file is sealed on a blockchain protocol. An encrypted certified copy of each document is always recoverable through a private key held only by the rightful Beneficiary.

This means you can prove — with absolute certainty — that a specific file existed at a specific date and time. Each upload carries an electronic signature that holds the value of certified date opposable to third parties.

Cloud archive

Encrypted upload through a private web interface.

End-to-end encryption

Only the Beneficiary's key can decrypt the file.

Tamper-proof

Any alteration is immediately detected by hash mismatch.

Legal certification

Date and time provable in audits and disputes.

Built-in governance

Three access levels, one chain of trust.

A hierarchical permission system so every department keeps control of its data — without giving anything away.

Super User

Unlimited access

Read and write across every file and folder. Adds, edits and removes administrators at any time.

Administrator

Full read & write

Visibility on all content. Adds employees and defines per-user permissions across folders and documents.

Employee

Custom permissions

Accesses and edits files according to the specific permissions assigned by the administrator.

How it works

Four steps. One certified file.

From upload to legal certification — every document goes through the same immutable path.

01 — UPLOAD

Encrypted upload

The file is encrypted in transit and at rest through the Arkivia web interface.

02 — HASH

Unique fingerprint

A cryptographic hash is generated and stored as the file's permanent fingerprint.

03 — CHAIN

Smart Contract

The hash is registered on blockchain through an immutable smart contract.

04 — CERTIFY

Legal certification

Permanent date and time proof — recoverable on demand for audits and disputes.

Decentralized backup

One server per client. One network across Europe.

Every Arkivia subscription ships with a physical archive server. Each server becomes a node of a decentralized European backup chain.

  • Physical hard backup

    A dedicated archive server is delivered with every subscription as a tamper-resistant local backup.

  • N redundancy

    Every file is replicated across multiple nodes — the more clients in the network, the higher the resilience.

  • European distribution

    Nodes are spread across the EU — geographic redundancy, GDPR-friendly, with always-growing accessibility.

Expense module

Travel expenses, fully provable.

Track every business trip with documented evidence — and equip your travelling staff with rechargeable corporate cards.

Questions

Frequently asked.

It means the timestamp on each document holds full legal value: in case of audit, dispute or litigation, you can prove that a specific file existed in that exact form at a specific moment — and that proof is admissible against any third party.

On three layers: (1) your private cloud archive, (2) the physical archive server delivered with your subscription, (3) the decentralised European node network — distributed across the EU with N redundancy for maximum resilience and GDPR compliance.

Files are encrypted and accessible only to users with the correct permissions defined inside your company. Even Arkivia operators cannot read content. The encrypted certified copy is recoverable only with the Beneficiary's private password.

Three: Super User (unrestricted), Administrator (read/write across all content, can manage employees) and Employee (custom permissions defined by an administrator). Permissions are granular down to the folder and document.

No. Arkivia partners with authorised third-party financial institutions which issue rechargeable Visa or Mastercard cards linked to your employee accounts. The Arkivia platform handles assignment, top-up and real-time transaction tracking.
