Spacecoin Achieves First Blockchain Transaction via Satellite Network
Spacecoin has achieved a milestone by executing a blockchain transaction entirely via space, bypassing terrestrial internet links. This proof-of-concept test demonstrated the feasibility of using satellite radio to relay cryptographic transactions.
End-To-End Transaction Via Satellite
- The transaction initiated in Punta Arenas, Chile, and was transmitted to the nanosatellite CTC-0 via S-band radio.
- It was downlinked to a ground station in the Azores, Portugal, covering approximately 7,000 kilometers.
- The test utilized the Creditcoin test network for processing.
- The aim was to verify the integrity of signature data through spaceborne links.
Partners And Planned Expansion
- The nanosatellite was provided in partnership with EnduroSat.
- Spacecoin plans to launch a CTC-1 cluster with three additional satellites in Q4 2025 to enhance coverage.
- This expansion will allow more uplink and downlink windows, particularly benefiting remote areas.
Technical Limits And Security Concerns
- Radio links face challenges like slow speeds, limited bandwidth, and increased latency.
- Security issues include potential interference, jamming, and misrouting risks.
- Robust operational security measures are necessary for future consumer services.
Potential Uses And Practical Hurdles
- Satellite routing could serve as a backup for remote or disaster-affected regions.
- The high costs of launching and maintaining satellites, along with necessary ground terminals, pose challenges.
- User adoption depends on cost-effectiveness, ease of setup, and reliable service.
Competition And Market Fit
- Spacecoin targets a market with existing players like Starlink.
- Success will require niche applications such as specialized blockchain messaging or regional partnerships.
- Economic viability is crucial alongside technical achievements.
