How Dictatorships Confront the Bitchat Messenger
A new wave of interest in Jack Dorsey's Bluetooth messenger Bitchat emerged in early 2026 amid escalating conflicts between citizens and authorities in Iran and Uganda. While the situation in Iran is nearly impossible to track due to communication blackouts, Uganda offers a clearer picture of digital repression and resistance.
In preparation for the presidential elections on January 15, the Ugandan government led by Yoweri Kaguta Museveni announced measures to counter the decentralized radio messenger. Museveni's opponent, singer and human rights activist Robert Kyagulanyi Ssentamu, known as Bobi Wine, urged supporters to install Bitchat to ensure a fair voting outcome.
In a recent article, ForkLog delves into the events in this small African nation and assesses the technical potential of mesh networks in real-world conditions of "silence."
Preventive Vacuum
In July 2025, Twitter co-founder and Block CEO Jack Dorsey introduced Bitchat, a messenger that operates via Bluetooth without an internet connection. Initially, this decentralized application, developed in just a few days using vibe coding, attracted only enthusiasts. However, within two months, Bitchat was actively used by participants in protests in Indonesia and Nepal, and by October, it became the only means of communication after a hurricane in Jamaica.
The peak interest in the product occurred in January 2026 due to mass protests in Iran. For demonstrators, Bitchat serves as an alternative tool to combat shutdowns, independent of government and corporate decisions.
Satellite internet would have been beneficial for the opposition in Uganda, where authorities traditionally block communication means ahead of presidential elections. However, Elon Musk is not known for his prompt charity. He only opened free access to Starlink in Iran on January 13, two weeks after the onset of mass street protests, when U.S. President Donald Trump officially expressed support for the demonstrators. Thus, civil society gained an additional tool for resistance alongside the "people's" Bitchat.
The Ugandan authorities prepared for a shutdown as early as late 2025. On December 19, the Tax Authority banned the import of Starlink terminals. Access to them was only granted to those with written permission from the army commander and son of the president, General Muhoozi Kainerugaba.
Despite the import ban, many terminals smuggled in earlier continued to operate. Consequently, the authorities decided to pressure Musk's company.
On January 1, at the request of the Uganda Communications Commission, Starlink activated a geolocation blocking tool. All equipment within the country became useless.
Charismatic opposition leader Bobi Wine opposed Museveni's policies and devised a plan to counter communication shutdowns to document the actual voting results.
On December 30, 2025, Wine urged supporters to download the Bitchat app. His idea was to use the messenger to share data from polling stations among observers in the absence of internet access.
Wine also appealed to Musk to reconsider his company's decision regarding Uganda and restore satellite coverage. In his post, he ironically noted the billionaire's joyful reaction to the overthrow of Nicolás Maduro in Venezuela while ignoring the situation in Africa.
Hey @elonmusk, as you cheer the fall of a dictator in Venezuela, here in Uganda your @Starlink has disabled citizens' access to its internet just days before the January 15th election in which we seek to peacefully end Museveni’s 40-year-old dictatorship!

Counteraction
Initially, the authorities firmly denied plans to shut down communications, but by January 13, they executed their intentions. The directive came from the Uganda Communications Commission. At 6:00 PM local time, public access to fixed and mobile internet was cut off, and the authorities imposed a ban on the sale and registration of SIM cards, as well as blocked outgoing roaming and VPN services.
The regulator cited recommendations from the Inter-Agency Security Committee to combat "misinformation, election fraud, and incitement to violence."
The Commission became the first government body in the world to declare a decisive counteraction against the decentralized messenger Bitchat, which surprised many. Most users involved in the topic on X did not understand how it was technically possible to suppress Bluetooth signals across Uganda.
The Google Trends search query graph reflects interest in the only remaining means of communication for the population. The last peak occurred just before the shutdowns on January 12-13.
One of the leading developers of Bitchat, under the pseudonym Calle, called on Ugandan programmers to join the project’s development.
you can't stop bitchat. you can't stop us.

I invite every Ugandan developer to join the global open source movement and contribute. we don't need anyone's permission to write code.
free and open source. unstoppable. from the people for the people. https://t.co/i7MzcEbsYS
Experts in mesh networks and concerned individuals indeed became active on X. Most commentators believed that the government would not find effective methods to counteract.

The principles of Bitchat's operation are elegantly simple and built on 50 years of developments and experiments with mesh networks.
A mesh network is a collection of computers organized in a cell-like structure, where workstations connect to each other and can act as switches for other participants. The application lacks centralized servers, and messages are stored in encrypted form on users' devices.
Smartphones A and B can communicate directly if they are nearby. Smartphone B can, in turn, connect with device C, which is too far from A. In this case, B acts as a relay, transmitting the message from C to A.
Intervening in Silence
On January 12, Calle presented an update for stable communication support in Uganda based on the encrypted messenger.
In the V1 Bitchat beta release, the firmware can turn a LoRa network device into a regular Bitchat node. Messages from nearby messenger users are automatically redirected through long-range antennas.

Theoretically, this provides a significant advantage, but in Uganda, importing the necessary devices into the country is currently nearly impossible.
According to Calle's report, on January 6, about 1% of the country's population downloaded Bitchat. According to Chromestats, as of this writing, the number of downloads of the Android version worldwide exceeded 1.5 million, adding about 125,000 users in a week.
Election Day
In the lead-up to the elections, the population of Uganda found itself in a state of digital isolation. In Kampala, security forces and armored vehicles were deployed.
The police, taking advantage of privileged internet access, did not forget to mention increased security measures.

Adding fuel to the fire was a sensational statement from the head of the Electoral Commission, Simon Byabakama.
On January 14, he reported receiving direct threats from unnamed high-ranking officials demanding that he not declare certain candidates as winners.
Byabakama publicly stated that he "does not engage in vote distribution" and will announce the results as they come from the polling stations.
Election Day will be significant not only for the people of Uganda but for the entire world. If Bobi Wine's team's plan succeeds, mesh networks will reach a new level.
The main question troubling advocates of freedom and equality is: what does the government have up its sleeve, and is there anything at all?
If the officials' statements are not a bluff, the world will witness another failure in the fight against dictatorship. But what methods might the security forces employ?
Shutting down a decentralized system like Bitchat is significantly more challenging than a conventional messenger, as it lacks central servers that can be blocked at the provider level. However, there are ways to disrupt the network "on the ground."
Potential technical methods for suppressing decentralized communication include:
- broadband jamming. Electronic warfare systems can "flood" the entire frequency range with powerful white noise, making any data exchange via Bluetooth impossible within a certain radius;
- targeted jamming of control channels. Bluetooth uses three specific channels (37, 38, and 39) for device discovery and message broadcasting. Modern electronic warfare systems can scan the airwaves and "jam" only these frequencies, preventing phones from "seeing" each other and forming a network;
- "Black Hole" attack. Agents can infiltrate crowds with specially modified devices that look like ordinary Bitchat nodes. They receive messages from neighbors but do not forward them. If there are many such "dead" nodes, the integrity of the network collapses, and messages get stuck within small groups;
- packet flooding. An attacking device can send thousands of junk messages per second, overwhelming the phone's processor and quickly draining the battery. Users will have to turn off Bluetooth to avoid device freezes;
- exploiting code vulnerabilities. In July 2025, a critical vulnerability was discovered in Bitchat's code related to packet signature processing. An attacker can send specially crafted "corrupted" data that causes the application to crash on all smartphones within Bluetooth range;
- "poisoned" installation files. Security services can create fake versions of Bitchat that look identical to the original but contain hidden code that blocks the transmission of certain messages or provides user coordinates to the authorities;
- triangulation and direction finding. Any phone with Bluetooth enabled constantly emits a radio signal. Using directional antennas and triangulation algorithms, security services can accurately locate active nodes of the mesh network in a crowd and physically detain relays.
On a national scale, the Ugandan government will not be able to "turn off" Bitchat. However, it is likely capable of managing several areas or polling stations.
In October 2025, as part of assistance, Russia provided the Ugandan army with military equipment worth $53 million. The equipment included obstacle-clearing vehicles, trench diggers, boats, workshops, and a coastal station.
The coastal station may include a basic setup with GPS, powerful transceiver antennas, radar, and communication means for identifying vessels, determining their dimensions, course, and coordinating with ships and aviation.

He held his final protest campaign speech on January 13 in Busiro East, followed by the communication shutdown and a temporary "house arrest" of the opposition leader. At the rally, Wine wore a bulletproof vest, and his usual red beret was replaced with a tactical helmet.
Shortly before these events, in an interview with The Telegraph, Wine admitted to experiencing physical and emotional exhaustion:
"Waking up every day knowing you will see someone get run over by a car, someone get maimed. You just don’t know who it will be today. It’s a huge stress, you know? But at the end of each day, you want to come back. Because while you mourn the losses, you see inspiration being born right before your eyes. And that makes it all worth the effort."
