Spacecoin has marked a major milestone in blockchain history by routing the world’s first end-to-end blockchain transaction through space. The achievement, showcased at the TOKEN2049 conference in Singapore, demonstrated that cryptographic security can be maintained during a complete round-trip beyond Earth’s atmosphere. Industry observers suggested that the breakthrough could reshape global internet connectivity and redefine the way blockchain networks operate.
The transaction was carried out using Spacecoin’s CTC-0 nanosatellite, confirming the company’s long-term mission of building a decentralized satellite-based internet. The signal originated in Punta Arenas, Chile, and was uplinked to the satellite through an S-band radio channel. It was then transmitted over 7,000 kilometers before being downlinked in the Azores, Portugal. The data was validated on the Creditcoin blockchain, verifying both the intercontinental transfer and the integrity of the cryptographic protocol.
Collaboration with EnduroSat
The demonstration was supported by EnduroSat, a European nanosatellite developer that recently secured €43 million in funding to expand production and in-orbit services. EnduroSat’s modular satellite platforms enabled Spacecoin to conduct its proof-of-concept under real-world conditions, providing a practical environment for testing blockchain transactions routed via space.
Executives from Spacecoin highlighted that this validation proved their vision of a decentralized, trustless internet in orbit could be technically feasible. They emphasized that blockchain transactions retained their security even when transmitted through satellite systems, marking a critical first step toward a broader space-based financial infrastructure.
Implications for financial freedom
By demonstrating that blockchain transactions can operate outside of terrestrial internet systems, Spacecoin has laid the groundwork for new possibilities in global finance. Analysts pointed out that such an achievement could help bypass restrictions posed by unreliable internet access, censorship, or capital controls in certain regions. For billions of people worldwide, space-based blockchain connectivity could unlock direct access to digital economies, ensuring greater autonomy and economic participation.
Industry experts further noted that this development strengthens the case for blockchain as a tool for financial sovereignty. A decentralized satellite network could facilitate secure, peer-to-peer transactions beyond the reach of centralized institutions or infrastructure, making it a transformative innovation for global connectivity.

Roadmap toward satellite constellations
Following the success of CTC-0, Spacecoin is preparing to expand its satellite network. The company announced plans to launch three additional satellites, referred to as the CTC-1 cluster, in the fourth quarter of 2025. This next phase will enable inter-satellite handoffs and wider demonstrations across multiple continents, further advancing the company’s vision of a decentralized orbital internet.
The upcoming constellation is expected to act as the backbone of a satellite-driven blockchain ecosystem, offering scalability and resilience unmatched by terrestrial networks. Observers believe that with continued progress, Spacecoin could position itself as a pioneer in merging blockchain technology with space-based communication systems.
A step toward decentralized internet infrastructure
The successful test at TOKEN2049 is seen as a pivotal moment in the convergence of blockchain and aerospace technology. By proving that cryptographic integrity can be preserved through space transmission, Spacecoin has opened a new chapter for decentralized connectivity. The company’s roadmap suggests that what began as an experimental demonstration could soon evolve into a global infrastructure capable of supporting secure financial transactions beyond traditional internet limitations.
