An anonymous developer has just introduced the Darkwire project – a platform that allows Bitcoin transactions to be sent even without Internet, using long-range radio technology (LoRa). This project is garnering strong attention in the crypto community as it promises to provide solutions for users in censored areas, power outages, or disaster-stricken regions.
Bitcoin transactions via radio waves?
Darkwire is an open-source project developed by a programmer using the pseudonym “cyber”, currently studying artificial intelligence. The project was submitted to the Bitcoin 2025 Official Hackathon with the goal of solving a very specific problem: How to send Bitcoin when the Internet is cut off?
Cyber explains, #Darkwire was created to serve areas "under censorship or politically sensitive" such as the India-Tibet border, conflict zones like Rafah Crossing, or regions with infrastructure destroyed by natural disasters. Not intended for ordinary users, Darkwire is aimed at "those who need absolute privacy or want to circumvent information and financial censorship."
How Darkwire works
The project utilizes LoRa technology – long-range radio waves capable of transmitting data over distances of 3–10 km – to create a decentralized mesh network made up of small devices such as Arduino UNO and LoRa modules.
The process of sending a Bitcoin transaction is as follows:
Users enter the wallet address and amount $BTC in the Darkwire interface.
Transactions are signed and formed into "hex" data (encoded).
This data is sent via USB port to a Darkwire node (LoRa device).
The node will fragment the data if necessary and transmit it via radio waves.
Other nodes in the mesh network will sequentially forward data to the node connected to the Internet.
The final node will broadcast the transaction to the global Bitcoin network.
Cyber's Darkwire wallet is like a version of Tor, but dedicated to Bitcoin – where you can still conduct financial communication without surveillance, even when completely cut off from traditional connections.
Challenges and development potential
Currently, Darkwire is still in the early stages. Some features such as message encryption, obtaining UTXO data, or integration with the decentralized communication platform Nostr are still not completed.
Some major limitations include:
Low speed of LoRa radio.
High sensitivity to terrain (obstacles, crowded urban areas...).
Dependent on nodes with Internet to broadcast transactions to the blockchain.
However, if the Darkwire network expands and the community contributes, these limitations can be overcome. Cyber expresses a desire to make Darkwire the industry standard for Bitcoin communication without Internet, especially in an increasingly controlled and closely monitored era.
Connecting to the crypto market
This project reflects an important direction in the development of crypto: the ability to survive and operate in harsh or censored environments. In the context of governments increasingly controlling the Internet and financial transactions, Darkwire could become a strategic tool for the Bitcoin community.
Users on exchanges like Binance should also pay attention to these types of projects – as they open up scenarios for using Bitcoin in emergencies, natural disasters, or where financial policies are tightened.
Risk warning:
Investing in and using cryptocurrency always carries high risks. The Darkwire project is still in the experimental phase and is not ready for widespread use. Users need to carefully assess before real implementation. Crypto is not suitable for everyone – please consider carefully before participating.
