In a groundbreaking development, researchers have demonstrated that Bitcoin Lightning Network transactions can theoretically be sent between Earth and Mars with a latency of just three minutes. This breakthrough hinges on leveraging optical communication links, such as those developed by NASA or potential future Starlink infrastructure, combined with an innovative interplanetary timestamping protocol. The system addresses the significant challenge of signal delay, which can extend up to 22 minutes one-way depending on planetary alignment, by optimizing data packet routing and synchronization. This advancement not only highlights the scalability and versatility of the Lightning Network but also opens new avenues for financial connectivity in space exploration and future extraterrestrial economies. The research underscores the potential for real-time, low-cost transactions across vast cosmic distances, paving the way for seamless economic activity between planets as humanity advances toward multi-planetary existence.
