A new open-source project called Darkwire was introduced at the Bitcoin 2025 hackathon, allowing users to send Bitcoin transactions without an Internet connection. The project is developed by an anonymous programmer “cyber”, who is currently studying AI and machine learning.

Darkwire uses long-range radio technology (LoRa) and a decentralized mesh network to transmit data such as Bitcoin transactions over distances of up to 10 km. Transactions are signed offline on a local Bitcoin wallet, then sent via radio waves to various nodes, until they reach a node with an Internet connection to be uploaded to the blockchain.

Cyber stated that Darkwire is particularly useful in areas that are censored, disaster-stricken, or where the government controls telecommunications infrastructure — such as the India-Tibet border or the Rafah crossing. “Bitcoin cannot help if the government cuts off the Internet, and Darkwire is the solution to that problem,” they shared.

Darkwire is still in beta, but plans to expand the feature and call on the community to contribute source code. Despite its limited bandwidth and reliance on Internet nodes, the project promises to become an important tool for Bitcoin in an environment of repression and censorship.
