Overview

• The transmission traveled more than 7,000 km from Punta Arenas, Chile, to the Azores, Portugal, using S-band links before validation on the Creditcoin test network.
• Spacecoin says the result shows encrypted blockchain data can leave Earth, pass through a low-Earth-orbit satellite, and return intact without touching terrestrial networks.
• The company currently operates one nanosatellite launched in December 2024 on a SpaceX Falcon 9 and plans to add three more in Q4 2025 to demonstrate cross-satellite capability.
• Reuters noted that earlier J.P. Morgan experiments involved satellite-to-satellite blockchain payments but did not fully avoid ground infrastructure, distinguishing Spacecoin’s test.
• Positioning itself as a decentralized alternative for regions with unreliable or censored access, Spacecoin remains far smaller than Starlink, which has roughly 8,000 satellites.
