Spacecoin:- Turns out blockchain and space are long-lost siblings having a very public reunion. Between Justin Sun’s space jaunts and Musk’s Doge-era theatrics, the story feels endless. The ongoing TOKEN2049 in Singapore added a new chapter when DEPIN Startup Spacecoin founded by Tae Oh in 2024 demoed real blockchain activity routed through low-earth orbit. On Wednesday, Spacecoin said it successfully routed the first end-to-end blockchain transaction through space. The proof-of-concept used Spacecoin’s CTC-0 nanosatellite to relay a signed blockchain message from Punta Arenas, Chile, to a ground station in the Azores. This amounts to a roughly 7,000-kilometre, intercontinental transit that was later validated on the Creditcoin test chain. The @_spacecoin team has successfully made a blockchain transaction on our first satellite (CTC-0). The transaction was sent from Chile to Portugal, 7,000 km away. Now we are moving on to the next mission. pic.twitter.com/R2a5Qo9WJD — Tae Oh 🐧 (@taelimoh) October 1, 2025 Spacecoin Achieves First Blockchain Transaction in Space Most web2’s satellite systems are centrally owned, closed, and controlled by a single company. Customers subscribe on the provider’s terms, and often need permission from governments or telcos to gain access. However, Spacecoin’s DEPIN constellation handles the transactions, data requests and transmission on blockchain – making the system permissionless. In this demonstration at TOKEN2049 by Spacecoin, it collaborated with European nanosatellite specialist EnduroSat. In this proof-of-concept, messages were uplinked to Spacecoin’s CTC-0 satellite from Punta Arenas, Chile via S-band radio waves. They were then re-transmitted from the satellite to a ground station in the Azores, Portugal using store-and-forward relay. The 7,000-kilometer transmission was successfully validated on the Creditcoin network, confirming that blockchain messages can be transmitted through space while preserving their validity. This means operators and users can now interact directly, without depending on a centralized entity. By designing the network this…
