HDMEx
Human Decentralized Message Exchange
Your data travels through people — not servers.
Offline-first, end-to-end encrypted messages and files — encrypted on your device, carried peer-to-peer by participants, and settled on-chain when connectivity returns. No central server ever sees your data.
- Offline-first · P2P · end-to-end encrypted
- Proof of Participation — secured and owned by those who carry it
- Fair & social economy — value goes to the people who do the work
- Mine from your phone — no proof-of-work, near-zero energy
- Post-quantum — encrypted against harvest-now, decrypt-later
- Chroma Guard + independent C++ chain — client-side keys, monthly rotation, not a fork
How it works
Encrypt & seal
Everything is encrypted on your phone (message, file, metadata) — no server to start.
Payment and keys travel inside a programmable capsule, sealed with the delivery.
Post-quantum encryption: protected against “harvest now, decrypt later”.
Carry P2P (Vx)
A carrier (Vx) relays the encrypted payload offline over a local Wi-Fi hotspot (physical handover) — never in clear.
Anonymous and silent: the carrier sees neither the sender nor the content.
The recipient (Dx) confirms receipt → the mission is validated.
Validate & finalize (PoP)
Proof of Participation: Vax validate blocks from their phone — no proof-of-work, near-zero energy.
When the network returns, events sync into signed blocks.
Value goes to those who do the work — no burn.
Roles: Cx initiates & pays • Vx carries • Dx confirms • Vax validates (PoP).
Modes: COURSE = one-time delivery • BAL = persistent mailbox.
Who it’s for
Journalists & sources
Move sensitive documents with no exploitable trace.
Legal & medical
Confidential files and patient records, traceable without exposing content.
Businesses
Sensitive data and recurring reports, encapsulated payments, very low cost.
NGOs & crisis zones
Works offline: physical handover, 100% offline mailboxes.
Imperfect connectivity
Built for the billions on intermittent networks.
Transport & IoT
Geo-tagged flows and low-connectivity sensors, no central server.
Security & cryptography
- Client-side keys: BIP-39 phrase → keys stored encrypted (Secure Enclave/Keystore); the seed never leaves the device.
- Chroma Guard: AES-256-GCM + SHA3-256, memory-hard stretching and monthly activity-driven rotation — against “harvest now, decrypt later”.
- Post-quantum: hybrid ML-KEM key seal, incomplete file (AONT) — the carrier never holds the whole file — and ML-DSA signatures.
- On-chain capsule (Header|Body|Tag): offline settlement travels encrypted, readable only by the recipient.
Internal HDMEx addressing is separate from external wallet addresses.
Native economy
Paid course
Each course, funded by the client (Cx), is split on confirmation: 82% carrier (Vx) · 15% relay-recipient (Dx) · 3% company.
Nothing is paid before the (Dx) confirmation.
No burn ever: everything is redistributed.
Vax reward & lean validation (PoP)
Vax validate blocks from a plain phone — no proof-of-work, near-zero energy footprint.
HDMEX reward on a decreasing, capped emission → low sell pressure.
A network owned by those who carry it.
Governance & fairness
The team proposes, Vax + team vote.
Built-in anti-collusion: no fake courses between close peers.
A social and fair economy: value goes to real work.
Referral & growth
A referral tree rewards those who grow the network.
Rewards from emission (mint), across several levels.
Aligned growth: you earn by helping others contribute.
