Spacecoin, aiming to create a decentralized communication network to potentially challenge SpaceX’s Starlink in the future, recently announced a significant achievement.
This week, the company revealed the successful transmission of secure data through their initial demonstration satellite. This confirms the satellite’s operational capability to handle encrypted transactions while orbiting the Earth.
The blockchain-based transaction, transmitted from a location in Chile to Portugal, effectively demonstrated the viability of transferring cryptographic signatures and protected data via a space-based relay.
Spacecoin’s founder, Tae Oh, explained in a video shared on X, “Is it possible to reliably transmit cryptographic signatures through space? This is crucial for building a decentralized network of communication satellites, enabling universally accessible connectivity. CTC-0, launched with SpaceX in December 2024, was specifically designed to address this question. Today, I am happy to report that CTC-0 successfully completed its objective.”
CTC-0, a compact satellite developed by Endurosat and launched as part of a Falcon 9 rideshare mission in December of last year, represents the first in a series of planned prototype satellite launches by Spacecoin. Following CTC-0, the company plans to launch three additional satellites, called CTC-1, which will be slightly larger. Future iterations will involve even larger satellites designed to enhance overall system performance.
This test comes as Starlink continues to strengthen its dominant position in the satellite-based broadband industry. Leveraging its own vertically integrated launch operations, SpaceX has deployed over 8,000 satellites into orbit and has acquired millions of subscribers worldwide. Several competitors, including Amazon’s Kuiper project, are also working to gain a foothold in the market.
However, Spacecoin differentiates itself from Starlink and other traditional broadband networks by adopting a decentralized approach built on “tokenized access”. The company intends to introduce “Starmesh,” a network focused on secure internet traffic, that is designed to ensure digital liberty, providing secure, anonymous browsing, and enabling access to decentralized online services.

Founded in 2022, Tae Oh’s Spacecoin is an offshoot of Gluwa, a company also founded by him and focused on providing financial services to emerging economies. Spacecoin’s network framework is intended to be based on the Creditcoin blockchain, which can provide customers with the ability to pay for connectivity and conduct other various financial interactions.
According to Spacecoin, “Unlike land-based networks, which are inherently susceptible to outages, censorship, and economic barriers to entry, a decentralized system employing satellites offers internet access globally, resists censorship attempts, and operates independently from monopolistic control.”
