DEPIN Project Spacecoin Executes First Blockchain Transaction in Low Earth Orbit

Space Coin:- Turns out blockchain and space are long-lost siblings who have a very public encounter. Between Justin Sun’s space travel and Musk’s play in the Doge era, the story seems endless. The ongoing TOKEN2049 in Singapore added a new chapter when DEPIN Startup Spacecoin, founded by Tae Oh in 2024, demonstrated real blockchain activity being guided through low Earth orbit.

On Wednesday, Spacecoin said it had successfully routed the first end-to-end blockchain transaction through space. The proof of concept used Spacecoin’s CTC-0 nanosatellite to transmit a signed blockchain message from Punta Arenas, Chile, to a ground station in the Azores. This equates to approximately 7,000 kilometers of intercontinental transit which was subsequently validated in the Creditcoin test chain.

Spacecoin achieves the first Blockchain transaction in space

Most web2 satellite systems are centrally owned, closed and controlled by a single company. Customers subscribe on the provider’s terms, often needing permission from governments or telecom companies to access. However, Spacecoin’s DEPIN constellation handles transactions, data requests and transfers via the blockchain – making the system permissionless.

For this demonstration at TOKEN2049 presented by Spacecoin, it collaborated with European nanosatellite specialist EnduroSat. In this proof of concept, messages were linked to Spacecoin’s CTC-0 satellite from Punta Arenas, Chile via S-band radio waves. They were then retransmitted from the satellite to a ground station in the Azores, Portugal using a store-and-forward relay.

The 7,000-kilometre transmission was successfully validated on the Creditcoin network, confirming that blockchain messages can be transmitted across space while maintaining their validity. This means that operators and users can now interact directly, without relying on a central entity.

By designing the network in this way, Spacecoin aims to reduce the risk of monopoly, improve resiliency, and ensure that access can be expanded to communities that have traditionally been ignored by centralized systems. Simply put, this is a capability that the company says can help bypass censorship, outages, and cost barriers on terrestrial networks.

Is the project trying to compete with Elon Musk’s Starlink?

A Reuters report The technology and idea may have instinctively hinted to you about that, however, on the issue of “competing with Elon Musk’s Starlink,” Tai told Block of Fame: “Not directly. Starlink is designed as a premium, high-bandwidth service, while Spacecoin is focused on something different: providing lifeline connectivity to the billions still offline. Our mission is to bring first-time users into the digital age by ensuring that Internet access is not only available, but practical and affordable for all underserved populations.”

This is also clear. Where Starlink operates as a closed, company-owned system, Spacecoin is an open, decentralized protocol. Governments, telecommunications companies and enterprises can contribute to the network’s satellite infrastructure, creating a common model for communication.

In that sense, Tai says, “it complements Starlink” and “doesn’t compete with it.” This, he says, is like meeting different needs with different business models – and together helping to expand reach across a broad range of global users.

However, this achievement becomes important for the industry by demonstrating that blockchain transactions can completely bypass traditional terrestrial Internet infrastructure.

Spacecoin’s near-term goal is to place several satellites in low Earth orbit so that we can provide 24/7 coverage along the equator. In the fourth quarter of 2025, the company will deploy three additional satellites, collectively called CTC-1, to enable inter-satellite deliveries and expand demonstrations with partners across multiple continents.

It is also preparing to launch commercial service in 2026 in several regions. Pricing will be maintained at about $2 per month per user, which Tai said “matches what people are already paying on average for mobile service in those markets.”
