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

01 / INTERNET

INTERNET SHUTDOWNS

Governments weaponize connectivity, shutting down access during protests (e.g., Sudan 2019, Nepal 2025).

02 / SUPPRESSING

SUPPRESSING EVIDENCE

Without connectivity, journalists cannot submit verifiable evidence of human rights violations.

03 / WHISTLEBLOWER

WHISTLEBLOWER RISK

Metadata leaks can cause physical harm. Traditional tools fail when the network itself is hostile or gone.

04 / PRIVACY

PRIVACY FAILURE

VPNs and Tor rely on an internet connection. When the plug is pulled, privacy tools become useless.

02 / Architecture

OVERVIEW

Arkiv DB-Chain

Storage Layer

Cryptographically verifiable records. Censorship-proof evidence trails. Final settlement layer.

01
Open-Arkiv Mesh

Transport Layer

BLE hopping mesh (BitChat fork). Device-to-device relaying. Works entirely offline.

02
xxDK Anonymous Layer

Privacy Layer

Built on xx-network (cMixx). Full metadata protection. No traffic analysis leakage.

03
Bluetooth Mesh Protocol

Last-Mile Truth

A Bluetooth Low Energy (BLE) mesh network that moves data device-to-device without internet.

04
On-Chain Anchoring

Beacon Nodes

Payloads are relayed opportunistically until they reach a beacon node, then anchored on-chain.

05
Cryptographic Signatures

Verifiable Evidence

Preserves anonymity using xx-network metadata protection. Verifiable cryptographic signatures for evidence.

06
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
