Storage Technology

Ouranoos is the encrypted, peer-to-peer cloud of the Empoorio ecosystem: your files are encrypted on your device, addressed by content, stored across independent nodes and paid for in DMS through pallet-storage-market on EmpoorioChain.

Regular access to the chain

Every storage deal is a contract on EmpoorioChain. Providers publish capacity and price per GB per block; clients pick a provider and the chain holds the terms. Since runtime 221 the pallet bills by the exact byte, so a 2 MB photo costs 2 MB — not a rounded gigabyte.

Engineered by Empoorio

The client is a Flutter app for Android, iOS, web and desktop; the market is a Rust pallet in the EmpoorioChain runtime; transport is IPFS. 135 tests, zero mocks: encryption, content addressing, proofs, payments and the provider mode are the real circuits, not demos.

Encrypted on the device Files are encrypted with AES-256 before they leave your phone or computer. Nodes store ciphertext they cannot read; the key stays with you.

Content addressing Each file is identified by its SHA-256 hash as a CIDv1. The same bytes always have the same address, so integrity is checked by the address itself.

IPFS transport Blocks travel over IPFS between clients and nodes. The first node runs on Empoorio's own server; the design is a mesh of independent providers.

pallet-storage-market Capacity, price and contracts live on chain. Billing in bytes since runtime 221; the price stays denominated per GB and block, the scale a user can reason about.

Paid in DMS Storage is paid in Dracma (DMS), the native unit of EmpoorioChain, with the fee estimated before you confirm. No card, no subscription.

Proofs of storage Providers submit proofs bound to the real file CID. A node that no longer holds the bytes cannot produce the proof.

Provider mode The same app can run as a node: publish capacity, accept deals and earn DMS. Coordinator calls carry a signed JWT; S3-style credentials are derived, rotatable and never stored in plain text.

Run an Ouranoos node

Spare disk and a stable connection are enough to publish capacity on pallet-storage-market. The provider mode of the app registers your node, submits proofs and collects DMS. Tell us where you are and what you can host.

How Ouranoos works

A conventional cloud keeps your files in one company's data centres, readable by that company, priced by that company and reachable only while your account exists. Ouranoos inverts it: the file is encrypted before upload, split into content-addressed blocks, stored by nodes that compete on price, and governed by a contract on a public chain you can inspect block by block.

Network transparency

Every provider, price and contract is public state on EmpoorioChain. The nodes page lists what is registered today; the docs describe the pallet calls, the proof format and how to read the storage market from any Substrate client.

Where Ouranoos stands today

Honest status, 16 September 2026: the app is in internal testing on Google Play (versionCode 2), the pallet is live on the public testnet with byte billing, and the market holds 0 providers and 0 contracts — the first node is Empoorio's own. There is no mainnet, and testnet DMS has no value. What exists is the circuit, verified end to end; what does not exist yet is the crowd of providers.

Your keys, your files

Ouranoos cannot read what you store, and neither can a provider. Biometric unlock is native (local_auth), sharing produces a permanent gateway link you control, and sign-in issues Empoorio's own JWT — nothing about your files depends on a third party's account system.
