Spacecoin says it reached a caller milestone successful its quest to physique a decentralized communications backbone that could 1 time rival SpaceX’s Starlink.
The institution said this week that it successfully transmitted secured information via its archetypal objection satellite, validating the spacecraft’s quality to execute encrypted transactions successful orbit.
The blockchain transaction, beamed from Chile to Portugal, served arsenic a proof-of-concept for moving cryptographic signatures and encrypted information done space.
“Can we nonstop cryptographic signatures to abstraction intact? Without it, we cannot physique a decentralized web of communications satellites and fulfill the imaginativeness of gathering permissionless connectivity,” Spacecoin laminitis Tae Oh said successful a video posted connected X. “That was the main ngo of CTC-0, that we launched December 2024 with SpaceX. And today, I’m gladsome to stock that CTC-0 fulfilled its purpose.”
CTC-0, a tiny outer built by Endurosat and launched connected a Falcon 9 rideshare successful December 2024, is the archetypal successful a enactment of prototypes that Spacecoin plans to launch. The adjacent 3 satellites, collectively called CTC-1, volition beryllium somewhat larger, followed by adjacent bigger spacecraft to boost performance.
The trial comes arsenic Starlink continues to cement its pb successful the outer broadband space. With its vertically integrated motorboat business, SpaceX has enactment much than 8,000 satellites successful orbit and has already signed connected millions of planetary customers. A fistful of competitors, see Amazon’s Kuiper, are besides positioning themselves against the company.
But dissimilar Starlink and different managed broadband networks, Spacecoin’s attack is based connected “tokenized access” and decentralization. The institution volition motorboat “Starmesh,” an encrypted net postulation network, that it says volition “maintain net state portion allowing safe, untraceable browsing and entree to decentralized web services.”

Founded successful 2022, Oh spun the task retired of Gluwa, a steadfast helium founded that provides fiscal services to emerging markets. Spacecoin’s net infrastructure would tally connected the Creditcoin blockchain, which would fto customers wage net fees and behaviour different fiscal transactions.
“Unlike terrestrial networks, which stay susceptible to outages, censorship, and outgo barriers, a decentralized satellite-based strategy tin present net entree that is global, censorship-resistant, and autarkic of monopolies,” the institution said successful a statement.
