Spacecoin beams encrypted blockchain data from Chile to Portugal

Spacecoin announced that its demonstration satellite CTC‑0 successfully transmitted an encrypted blockchain transaction from Chile to Portugal, confirming that cryptographic signatures can survive a full orbital relay [1]. The 7,000‑km data burst traveled via a microsatellite built by EnduroSat and launched on a Falcon 9 rideshare in December 2024, marking the first instance of a blockchain record passing entirely through space without terrestrial internet [3].

Founder Tae Oh framed the test as a proof‑of‑concept for “Starmesh,” a token‑based, decentralized satellite network that would let users pay for internet access and store data without a single controlling entity [1]. Unlike Starlink’s vertically integrated model—over 8,000 satellites serving millions—Spacecoin’s approach relies on a swarm of small, low‑Earth‑orbit craft that any developer, telecom, NGO, or end‑user could join [1][3]. The company plans to launch three additional satellites (CTC‑1) by the end of the year, scaling from the single‑satellite prototype to a functional constellation [1][3].

The test also serves a broader market narrative. Spacecoin targets regions where connectivity is unreliable, censored, or prohibitively expensive, promising a censorship‑resistant, globally accessible internet layer built on the Creditcoin blockchain [1][4]. By demonstrating that blockchain data can be transmitted intact through orbit, the startup claims to have validated the core technical architecture needed for a decentralized satellite internet, a claim not yet matched by competitors such as Amazon’s Kuiper [1].

If the prototype’s success translates into a scalable network, Spacecoin could introduce a new competitive pressure on Starlink’s dominance, especially in niche markets that value privacy and open access. However, with only one operational satellite and a modest launch cadence, the venture remains a long way from the scale of SpaceX’s fleet, leaving its ability to deliver reliable broadband at commercial volumes uncertain. The next milestone will be whether the upcoming CTC‑1 batch can demonstrate seamless handoffs and inter‑satellite links, a test that will determine if the vision of a truly decentralized space‑based internet is feasible.
