Locha Mesh

What is the Locha Mesh?

During the year 2018 in Venezuela there were power blackouts throughout the whole country which left cities without power for weeks, even cell towers run out of power supply after a few days, so despite people managed to charge their phones with generators or cars' battery, there wasn’t any cell service for them to communicate with others. No calls, no SMS, no mobile data.

How do you communicate and do commerce when there is no communication infrastructure, nor power grid at all?

The Locha Mesh is an open-source and open-hardware project initiated by the non-profit Bitcoin Venezuela in 2018, to create the software, protocol, and hardware needed for a resilient, decentralized, mesh network of devices capable of transmitting messages, data, Bitcoin transactions, and services completely off-grid without having to rely on an Internet connection or even the electrical grid, for disaster hit countries and privacy-concerned individuals and groups.

The Locha Mesh devices are battery powered and could also use solar panels. There will be custom made hardware, the Turpial, which is mobile-first so you can carry it around. (you can pre-order a Turpial device by making a donation to the project) and also DIY alternatives. The Turpial device can also be attached to a computer (desktop, laptop, Raspberry Pi...) to offer services to others and get paid in Bitcoin, Lightning Network, and Monero RPC-Pay. You can add a bigger antenna and power amplifier to serve a wider area or reach longer distances.

Getting started

In this page you will find all the information related to the progress of the project, in two languages, Spanish, and English. This work is still under development stage, but all days we are updating the information to expose all the progress about the project

The Locha Mesh is under active development. If you are a C/C++ developer and you want to join the development efforts, or you are a maker and would like to setup the development kits to have them ready for when the firmwares are ready, or if you are a phreaker and you want to hack new ways for decentralized communications, please follow the instructions below on how to get started.

What's in the code?

  • The first application that communicates with the Turpial devices can be found here.

  • Our firmware for the Turpial boards (ESP32) can be found here.

  • Our firmware for the radio modules can be found here.

  • The routing protocol and code for the mesh network can be found here.

  • You can find a Locha Mesh simulator, datasheets, and more in the Bitcoin Venezuela organization.
