Nine months, six phases, one honest label.
The plan the product is actually built against. It ends at a public release marked Early Access, because range is limited and delays are expected, and saying so is part of the design.
Development plan
MVP horizon · 9 monthsUpdated · July 2026- 01ShippedMonths 1-2
Proof of concept: basic mesh messaging
Two or more devices discover each other and exchange messages with no internet.
- Minimal BLE mesh with one-hop messaging
- Simple pass-it-along delivery; no encryption or payments yet
- Success is phones chatting with Wi-Fi and cell switched off
- 02ShippedMonths 3-4
Encrypted, multi-hop prototype
Add encryption and message relaying across several phones, and stand up the wallet on Bitcoin's test network.
- Every phone gets its own identity key; messages are encrypted and signed with a proven open-source library
- Messages hop with a strict limit, are never carried twice, and are proven across a three-phone chain
- A wallet on Bitcoin's test network: create an address, sign a practice payment
- Independent radio monitoring confirms nothing readable ever leaves the phone
- 03In progressMonths 5-6
Offline transaction and relay integration
Real offline payments, carried by the mesh and settled on the test network. This is the working internal MVP.
- Real payments on the test network: amounts, fees and signing, end to end
- A signed payment crosses the mesh and is broadcast by whichever phone has internet
- End to end: an offline phone pays another, the mesh carries it, a third phone with internet broadcasts it, and the test network confirms
- Confirmation comes back to the mesh automatically, with retries if a broadcast fails

Internal alpha testing
Rigorous testing against real fleets and real movement.
- Stress tests with 5 to 10 phones; delivery tuned so a crowd stays quiet and reliable
- Range and mobility tests, including the walking data-mule test
- Internal audit: encryption round-trips, payment validity, and the delivery limits
- Battery and memory testing under slow, long-range radio conditions
- 05PlannedMonth 8
Public beta: field test
Real-world feedback from 20 to 50 testers in places the network is genuinely absent.
- TestFlight and closed Play Store beta
- Scenarios: festival crowd, no-coverage ground, multi-hop chat, tester-to-tester transaction
- Expected additions: add a contact by QR code, a nearby-devices counter, message resend
- 06PlannedMonth 9
MVP launch
Public release, labelled Early Access, with its limits written down.
- Security review of the code, ideally an external audit of the crypto implementation
- User guide stating the limits honestly: range is limited, expect delays
- Release to both stores with crash monitoring and a support channel
The foundation, not the ceiling.
Each of these is a plug into an existing interface rather than a rewrite. The mesh treats payloads as opaque, so a new chain changes the wallet and nothing else.
LoRa via paired hardware
Kilometres per hop instead of tens of metres. One equipped node lifts an entire cluster.
Ethereum and a stablecoin
A second currency proves the mesh does not care what it carries.
Lightning
Research on offline mesh Lightning reports up to 95% success in simulation.
Satellite export
A signed transaction leaving by an Iridium-class uplink when no node ever reaches the internet.
Nostr and Matrix bridging
Two meshes that were never in radio range exchanging messages once either touches the internet.
Solar LoRa repeaters
A lightweight always-on build of the mesh, deployable on hilltops by anyone.
