Spacecoin has marked a historic milestone in blockchain technology by successfully executing the first end-to-end blockchain transaction routed through space via satellite infrastructure. The decentralized physical infrastructure network (DePIN) project demonstrated this groundbreaking proof-of-concept during the TOKEN2049 conference in Singapore, transmitting a signed blockchain message across 7,000 kilometers from Chile to Portugal through low Earth orbit.
The transaction utilized Spacecoin’s CTC-0 nanosatellite to relay encrypted data from Punta Arenas, Chile, to a ground station in the Azores, Portugal, using S-band radio waves and store-and-forward relay technology. This intercontinental transmission was successfully validated on the Creditcoin test chain, confirming both the satellite’s relay capability and the integrity of the blockchain protocol implementation in space-based environments.
The demonstration was conducted in collaboration with EnduroSat, a European nanosatellite specialist that recently secured €43 million in funding to expand its production and in-orbit services. EnduroSat provided the modular satellite platform technology that enabled Spacecoin’s CTC-0 satellite to maintain cryptographic integrity during the space-based transmission, proving the technical viability of decentralized satellite internet infrastructure.

Unlike traditional terrestrial networks that remain vulnerable to outages, censorship, and cost barriers, Spacecoin’s approach leverages blockchain technology to create a permissionless satellite constellation. The system handles transactions, data requests, and transmission entirely on blockchain infrastructure, eliminating the need for centralized control by single companies or government permissions that typically govern satellite communications.
“This successful test proves that our vision of trustless, satellite-based internet connectivity is technically viable,” said Adam Wexler, Spacecoin’s director of systems architecture. “We’ve demonstrated that blockchain transactions can maintain their cryptographic integrity when routed through space, which is a fundamental first step in the practical implementation of the Spacecoin Data Network protocols.”
Spacecoin’s Vision for Decentralized Internet
The successful space-based blockchain transaction represents a significant step toward building a truly decentralized internet infrastructure that operates independently of traditional ground-based networks. Spacecoin’s approach differs fundamentally from existing satellite internet providers like SpaceX’s Starlink, which maintains centralized control over its constellation and requires customers to subscribe under the provider’s terms.
The implications extend far beyond technical achievement, particularly for the billions of people living in regions with capital controls, restricted financial access, or unreliable internet connectivity. Satellite-routed transactions could provide economic freedom for users in censored or controlled network environments, enabling global peer-to-peer cryptocurrency transactions without dependence on banks or payment processors.
Spacecoin’s founder Tae Oh, who established the company in 2024, emphasized the critical importance of maintaining cryptographic signatures during space transmission. “Can we send cryptographic signatures to space intact? Without it, we cannot build a decentralized network of communications satellites and fulfill the vision of building permissionless connectivity,” Oh explained in a video posted on social media platform X.
The project addresses fundamental challenges in current satellite communication systems, where most providers maintain closed, centrally controlled networks. By implementing blockchain-based protocols, Spacecoin aims to create an open, permissionless system that could democratize access to satellite internet services and reduce dependence on terrestrial infrastructure controlled by governments or corporations.
Technical Implementation and Satellite Infrastructure
The CTC-0 nanosatellite, launched aboard a SpaceX Falcon 9 rideshare mission in December 2024, serves as the first prototype in Spacecoin’s planned constellation. The small satellite was specifically designed to test the core functionality of transmitting blockchain transactions while maintaining cryptographic integrity in the harsh environment of low Earth orbit.
Technical specifications of the demonstration reveal the sophisticated engineering required to achieve space-based blockchain transactions:
- Transmission distance: 7,000 kilometers intercontinental range
- Communication method: S-band radio waves with store-and-forward relay
- Validation network: Creditcoin test chain confirmation
- Satellite platform: EnduroSat modular nanosatellite technology
- Launch vehicle: SpaceX Falcon 9 rideshare mission
The store-and-forward relay technology allows the satellite to receive, store, and retransmit data as it orbits Earth, enabling communication between ground stations that are not simultaneously visible to the satellite. This approach overcomes the limitations of direct line-of-sight communication and enables global connectivity through a distributed satellite network.
Spacecoin has announced plans to scale operations significantly in the coming months. The company will deploy three additional satellites, collectively designated CTC-1, during Q4 2025. These larger satellites will enable inter-satellite handoffs and expand demonstration capabilities with partners across multiple continents, laying the foundation for a comprehensive decentralized internet infrastructure.
Market Implications and Future Plans
The successful demonstration positions Spacecoin as a potential competitor to established satellite internet providers, though the company’s decentralized approach represents a fundamentally different business model. While SpaceX’s Starlink has already deployed over 8,000 satellites and secured millions of customers through its vertically integrated approach, Spacecoin’s blockchain-based system could appeal to users seeking censorship-resistant connectivity.
The broader implications for the cryptocurrency industry are substantial, particularly for DePIN projects that combine blockchain technology with physical infrastructure. Spacecoin’s achievement demonstrates the practical viability of decentralized satellite networks, potentially inspiring similar projects and investment in space-based blockchain applications.
Competition in the satellite internet market continues to intensify, with Amazon’s Project Kuiper and other companies positioning themselves against SpaceX’s dominance. However, Spacecoin’s focus on decentralization and blockchain integration creates a unique value proposition that could capture market segments underserved by traditional providers, particularly in regions with restricted internet access.
The company’s roadmap extends beyond the current demonstration phase, with plans to expand the satellite constellation and develop more sophisticated protocols for decentralized internet services. The CTC-1 satellites scheduled for Q4 2025 deployment will test inter-satellite communication capabilities, a crucial step toward building a fully autonomous space-based network.
Industry experts note that the success of blockchain transactions through satellite networks could accelerate adoption of decentralized internet technologies. The demonstration proves that cryptographic operations can function reliably in space environments, potentially opening new applications for blockchain technology beyond traditional financial transactions.
Technical analysis from industry publications suggests that Spacecoin’s approach could complement existing satellite internet infrastructure rather than directly competing with it, potentially creating hybrid systems that combine centralized efficiency with decentralized resilience.
