INTERNET SHUTDOWNS
Governments weaponize connectivity, shutting down access during protests (e.g., Sudan 2019, Nepal 2025).
SIGNAL
When the internet goes dark,
truth goes dark.
Open-Arkiv is a censorship-resistant Bluetooth mesh data protocol that allows critical information to move phone-to-phone during internet shutdowns, creating immutable evidence trails.
v.01 / Experimental Build
03 / Problem
THE CORE ISSUE
SUPPRESSING EVIDENCE
Without connectivity, journalists cannot submit verifiable evidence of human rights violations.
WHISTLEBLOWER RISK
Metadata leaks can cause physical harm. Traditional tools fail when the network itself is hostile or gone.
PRIVACY FAILURE
VPNs and Tor rely on an internet connection. When the plug is pulled, privacy tools become useless.
02 / Architecture
OVERVIEW
Three-layer architecture: Storage, Transport, and Privacy. Built for edge cases where everything else fails.
Arkiv DB-Chain
Storage Layer
Cryptographically verifiable records. Censorship-proof evidence trails. Final settlement layer.
Open-Arkiv Mesh
Transport Layer
BLE hopping mesh (BitChat fork). Device-to-device relaying. Works entirely offline.
xxDK Anonymous Layer
Privacy Layer
Built on xx-network (cMixx). Full metadata protection. No traffic analysis leakage.
Bluetooth Mesh Protocol
Last-Mile Truth
A Bluetooth Low Energy (BLE) mesh network that moves data device-to-device without internet.
On-Chain Anchoring
Beacon Nodes
Payloads are relayed opportunistically until they reach a beacon node, then anchored on-chain.
Cryptographic Signatures
Verifiable Evidence
Preserves anonymity using xx-network metadata protection. Verifiable cryptographic signatures for evidence.
05 / Threat Models
TWO DISTINCT THREAT MODELS
Open-Arkiv is designed for specific edge cases where safety is paramount.
Mode 1
Signed Mode
Journalists & Verifiable Reporting
- •Passkey/fingerprint local wallet generation
- •Includes GPS + Timestamp metadata
- •Cryptographically signed evidence
Mode 2
Whistleblower Mode
Anonymous & Deniable
- •No signatures, no identity attached
- •xxDK encryption & metadata protection
- •Maximum deniability under surveillance
