The cloud is someone else's computer, and they hold the keys. OuranoOS is the ecosystem's attempt at the alternative: encryption on your device, storage bought from independent nodes through EmpoorioChain's market, and a price meant to undercut the incumbents. This post is what the app is and what testing it on a real device revealed.
What it does
- Encrypts files locally before anything leaves the device.
- Commits each file through
pallet-blob-storageand buys storage from providers through the storage market, billed by the byte. - Pays in DMS from a linked Eoonia account; the provider is verified by
pallet-storage-oracle. - Shows quota, usage and cost, with a simulator for planning.
The tablet review
In August 2026, with 142 tests passing, the app was installed on a tablet and used the way a person would. Seven problems appeared:
- UI claims the backend did not support.
- An invented 5 TB quota shown as if it were the user's.
- A cost simulator 17× too cheap.
- Division by a quota of zero →
NaNon screen. - Layout overflows on the device's real dimensions.
- A login path that never issued a session token (found earlier, in a July review).
- "Multi-provider replication" that wrote copies to the same device.
All fixed. The rule the team drew: finishing a batch includes launching the app and walking through it. Screen overflow is now a test — every screen rendered at both devices' logical sizes, zero overflows allowed — rather than something a screenshot might catch.
Signing
A subtler finding from the same period: the shared Dart SDK's transaction builder returned a call object with no sign() method, so 35 extrinsics the app thought it could send would never have been signed — hidden behind a UI that looked complete. Corrected in the SDK; Ouranoos and Eoonia both consume the fixed version. And the SDK's chain service connected on construction, so calling initialize() threw already connected and Ouranoos started with no chain at all; guarded.
Status
- App:
com.empoorio.ouranoos, closed alpha on Google Play, version 2 as a draft. Signing key registered so the store can re-sign it. - Web and privacy policy: live at
ouranoos.com, policy under/docs/resources/privacy. - Providers: none independent yet. The storage market pays providers; there are no third-party providers to pay. Until there are, Ouranoos stores against the ecosystem's own nodes, and its "cheaper than the incumbents" claim is a target derived from the market's pricing, not a delivered price.
- Chain: storage market billing by bytes since runtime 213; blob commitment 0.000095 DMS per MB on the testnet.
Petabytes, honestly
A multi-petabyte encrypted cloud needs erasure coding, sampling-based availability proofs and hundreds of providers. Ouranoos has an app that encrypts and commits, a market that bills by the byte, an oracle that checks whole blobs, and zero external providers. The distance between those two sentences is the roadmap, and this page will shorten it as the provider count rises above zero.
Based on the Ouranoos device review (2026-08), the SDK signing fix, the Ouranoos Play release status and the runtime 213 change.
