Hello everyone,
Security on the Internet, in its current form, is an illusion. The centralized infrastructures that dominate the digital world are vulnerable to outages, censorship and surveillance: a single actor can cut the service, read the data, or be forced to do so. HDMEx offers a fundamentally different alternative for exchanging sensitive files and value: decentralized, discreet, resilient offline, and carried by a human network of couriers.
I’m Carl. It’s not my real name, but I like it.
I’m a French speaker and I’ve spent a lot of time going back and forth between the French and Geneva crypto communities.
So I posted in the French section first, and this is the English topic.
HDMEx is a concept I’ve been developing for more than 2 years, and I’ve learned a lot along the way.
I’m here because I’m about to release a beta on the test chain, and I’m looking for a few early adopters to deliver, mine and verify.
The beta should be out in early January 2027, but I need a few partners to test in real conditions before that, because even a beta has to perform.
What you will never find at HDMEx:
features coming from the American giants: Apple, Google, Facebook, Amazon and others
private data going through the Internet
fundraising
airdrops
What you will always find at HDMEx:
PoP
P2P Wi-Fi hotspot
bearer notes
The pillars of the project:
A discreet delivery network. A sender (Cx) entrusts an encrypted file to a courier (Vx), who hands it to a recipient (Dx).
No names, no direct contact between the parties. The handover happens over the local Wi-Fi of the HDMEx router, a small pocket router carried by the courier, which never goes on the Internet.
Confidentiality designed for tomorrow. With Chroma Guard, everything is encrypted on the user’s device. The courier carries an incomplete file he cannot read, and files are protected against the quantum computers of tomorrow.
A chain mined by the Vax’s devices. Blocks are produced and verified by the participants’ devices (their phone, or a computer left on) using Proof of Participation: the chances of mining follow real participation, and verification is the best rewarded. No server farms, no specialized machines.
A fair launch. No token exists at the start: no team reserve, no reserved allocation, no presale. Every HDMEx is born from mining and verification, then circulates through deliveries and purchases.
Issuance that follows usage. The chain creates HDMEx at the pace senders actually need them. No artificial cap, no halving: a continuous, modest issuance ensures there will always be HDMEx available and Vax rewarded.
A chain no one controls. No administrator key, no off switch, no central treasury. The HDMEx structure can neither stop the chain, nor change its rules alone, nor punish or pardon anyone. It is paid only through a small commission on deliveries and through the opening of the secure chat, never through mining.

Looking forward to reading you,
