My phone is a lifeline for my family, yet out here it might as well be a brick." Fisherman from southern India For millions of people, connectivity is not a convenient luxury; it is the difference between safety and danger, opportunity and isolation. In the Nigerian port of Lagos, fishers speak of sending text messages only when they are close enough to shore to catch a faint signal. In the forests of the Democratic Republic of the Congo, aid workers carry satellite phones because mobile towers don’t exist. Globally, about 2.6 billion people remain offline—roughly a third of the world’s population. At the same time, 1.4 billion adults lack access to formal financial accounts, the vast majority living in regions vulnerable to climate and economic shocks. 2.6 billion people remain offline 1.4 billion adults lack access to formal financial accounts These twin divides—digital and financial—keep billions of people from participating in modern society.  Spacecoin, an ambitious initiative spun out of financial‑technology company Gluwa, proposes to tackle both at once.  By combining low‑Earth‑orbit (LEO) nanosatellites with blockchain‑based economic incentives, Spacecoin aims to build a decentralized physical infrastructure network (DePIN) that delivers affordable internet access and trustless financial services.  This article explores the scale of the connectivity crisis, the promise and pitfalls of satellite networks, and how blockchain technology could transform the way we connect and transact. Gluwa low‑Earth‑orbit (LEO) nanosatellites blockchain‑based economic incentives decentralized physical infrastructure network (DePIN) The Digital Divide: A Silent Emergency Despite progress over the last decade, connectivity gaps are stark. The International Telecommunication Union (ITU) estimates that 68 % of the global population is online, but in low‑income countries only 27 % are connected. Rural areas lag far behind cities; about 83 % of urban dwellers use the internet compared with 48 % of rural residents. Cost remains a major barrier: in some low‑income countries, the price of a fixed broadband subscription consumes nearly a third of the average monthly income.  Emerging economies also suffer from unreliable infrastructure and frequent power cuts, making terrestrial networks impractical. 68 % of the global population is online 27 % 83 % 48 % nearly a third of the average monthly income Even where towers exist, politics can intervene. In conflict zones, authoritarian governments shut down networks to stifle dissent. In remote regions, telecommunication monopolies set high prices for low‑quality service. Without reliable connectivity, people cannot access online education, telemedicine, e‑commerce or digital IDs. Worse still, they remain excluded from the digital economy. As the World Bank notes, transaction accounts are the gateway to financial services; expanding digital finance has reduced the number of adults without accounts from 2.5 billion in 2011 to 1.4 billion in 2021, yet much work remains. transaction accounts are the gateway to financial services 2.5 billion in 2011 to 1.4 billion in 2021 Why Satellites and Blockchain? Physical Decentralization Spacecoin’s core idea is to create a physically decentralized network using fleets of small satellites. Traditional telecom infrastructure depends on centralised towers and fibre‑optic cables; by contrast, a constellation of LEO satellites could blanket the globe, especially underserved regions. According to Spacecoin’s official site, this physical decentralization eliminates reliance on central authorities, reducing censorship risks and outages while ensuring coverage in remote areas. physically decentralized network a constellation of LEO satellites could blanket the globe Unlike geostationary satellites, which orbit high above the equator and suffer from high latency, LEO satellites orbit much closer to Earth, enabling faster data transmission and direct connections to smartphones. Spacecoin plans to deploy nanosatellites equipped with 5G non‑terrestrial network (5G‑NTN) capabilities. Users could connect to these satellites just as they connect to cell towers, but from almost anywhere on the planet. Because the satellites do not require costly ground stations or towers, the company believes it can offer data plans in emerging markets for as low as US$1–2 per month, dramatically undercutting existing providers. 5G non‑terrestrial network (5G‑NTN) as low as US$1–2 per month Transparent & Trustless Operations Running a global satellite network is complex. Satellite operators must allocate bandwidth, process payments, handle roaming across jurisdictions and ensure service quality. Spacecoin proposes to manage these operations on the Creditcoin blockchain, a Layer‑1 network designed for real‑world applications. The project’s website highlights that blockchain technology brings transparency and trustlessness, allowing smart contracts to manage data transmissions and payments without a central authority.  Transactions are recorded on‑chain, making the system resilient against fraud and censorship. Creditcoin blockchain transparency and trustlessness Borderless Payments One of the biggest obstacles to connecting the unconnected is the lack of payment infrastructure. Many potential users have no bank accounts or credit cards, and cross‑border payments are expensive. By embedding payments within a blockchain, Spacecoin can accept cryptocurrency from any compatible wallet. The project emphasises that a blockchain‑native system removes financial and country borders, enabling people in regions with limited banking infrastructure to pay network fees. Creditcoin’s universal smart contract layer allows users to pay with assets across multiple networks without the need for complex bridges. Users could even buy now, pay later (BNPL) for their internet connectivity through Credal, a credit‑scoring system built on Creditcoin. removes financial and country borders buy now, pay later (BNPL) Credal The First Steps: Launching a Satellite Network Spacecoin is not just an idea on a whiteboard. On December 21, 2024, the company successfully launched CTC‑0, its first test satellite, via a SpaceX Falcon 9 rideshare mission. Shortly after launch, founder Tae Oh reported that the team had established regular communication with the satellite. The 8U nanosatellite—built by Bulgarian manufacturer EnduroSat—will initially demonstrate space‑enabled text messaging to a handheld antenna and eventually connect directly to standard smartphones. A second, larger 16U satellite (CTC‑1) is slated for 2025, with plans to transition to microsatellites to boost performance. December 21, 2024 CTC‑0 Tae Oh 16U satellite (CTC‑1) Spacecoin’s decentralized model extends beyond technology to ownership. Anyone who adheres to the open standards and is willing to invest in a satellite can join the network, according to CEO Stuart Gardner. Investors receive a pro‑rata share of revenues based on how often their satellite is used. This cooperative model means a regional telecom operator in Nigeria could launch satellites to serve local customers and earn additional revenue when its satellites pass over other regions. The company also plans to open‑source its satellite designs so other manufacturers can build compatible hardware, increasing decentralization. Anyone who adheres to the open standards and is willing to invest in a satellite can join the network Stuart Gardner pro‑rata share of revenues open‑source its satellite designs Spacecoin is targeting markets with immediate needs. Gardner noted that Nigeria, one of the first countries to allow tests of Mobile Satellite Services (MSS) in the S and L bands, will host initial trials. Beyond Nigeria, potential customers range from fishermen in southern India, whose daily catch depends on receiving weather updates, to farmers in Ethiopia, where mobile coverage is sporadic. By sharing infrastructure across time zones and jurisdictions, satellite owners can monetize idle capacity and reduce per‑user costs. Spacecoin estimates that sharing could reduce monthly internet costs to around $1–2 per user in emerging markets. fishermen in southern India $1–2 per user The Missing Ingredient: Trust and Payments Connecting everyone is only half the battle. Without reliable payment systems and credit histories, connectivity alone cannot unlock economic opportunity. That’s why Spacecoin relies on Creditcoin, a blockchain built for financial coordination, and the Credal credit‑rating system developed by Gluwa. The Creditcoin team argues that LEO satellites expand reach, but they do not solve deeper challenges such as cross‑border payments and identity verification. Creditcoin offers an open, interoperable trust layer, enabling users to transact securely, prove identity without centralized gatekeepers and verify data on‑chain. Creditcoin Credal expand reach Creditcoin offers an open, interoperable trust layer Smart Contracts, Escrow and On‑Chain Reputation Spacecoin leverages Creditcoin’s built‑in smart contracts to manage bids for bandwidth, match users with available satellites and automate payments. When a user requests connectivity, they deposit Spacecoin tokens into escrow; the tokens are released to the satellite operator only after the user acknowledges satisfactory service. This escrow mechanism prevents free riders and ensures that transmitters are compensated fairly. The network also incorporates a credit system: transmitters can report users who fail to confirm data transmissions, building a reputation score that influences future access. In time, governance will transition from the Spacecoin Foundation to token holders, making network rules more democratic. smart contracts Spacecoin tokens into escrow credit system Financial Inclusion Via Gluwa The synergy with Gluwa extends beyond infrastructure. Gluwa’s decentralized financial platform connects investors with borrowers in emerging markets using the Creditcoin network. A Microsoft case study on Gluwa notes that about 1.4 billion people are underbanked or unbanked, often lacking the credit histories needed to secure loans. By recording loans on Creditcoin’s immutable ledger, Gluwa allows investors to fund entrepreneurs in developing countries with greater transparency. According to Gluwa’s leadership, a decentralized, permissionless blockchain network removes national jurisdictional limits and connects users across borders.  As a result, everyday investors can fund microloans in Nigeria or Ghana while borrowers build on‑chain credit histories. Gluwa 1.4 billion people are underbanked or unbanked decentralized, permissionless blockchain network removes national jurisdictional limits When combined with Spacecoin’s satellite network, Gluwa’s financial tools could enable a fisherman not only to send weather updates but also to take out a small loan for a new boat.  The monthly data fee—facilitated by Creditcoin’s escrow system—would simultaneously build the user’s credit reputation.  Over time, this could unlock larger loans or other financial products.  In this way, connectivity and finance become mutually reinforcing. take out a small loan for a new boat build the user’s credit reputation Challenges and Considerations Spacecoin’s vision is compelling, but significant hurdles remain. Launching and operating a satellite constellation is capital‑intensive. Even nanosatellites cost millions of dollars to design, build and launch, and they have limited lifespans. Regulators must grant licenses for spectrum and orbital slots, and international coordination is complex. The company faces competition from established players such as Viasat and Iridium, and from newer entrants like SpaceX’s Starlink, which also aims to provide direct‑to‑smartphone connectivity.  While blockchain technology can automate payments, it must handle high volumes of microtransactions without prohibitive fees or delays. Viasat Iridium SpaceX’s Starlink Furthermore, community adoption will depend on the affordability and usability of the service.  Many of the unconnected live in regions with limited purchasing power; even $1–2 per month may be unaffordable without subsidies or novel financing models.  Building trust in blockchain‑based payment systems will require education and user‑friendly interfaces.  Cybersecurity is another concern: satellites and ground stations could become targets for hackers, and on‑chain transactions must be protected against theft. Why Spacecoin Matters Despite these challenges, Spacecoin’s approach addresses several systemic problems. By physically decentralizing infrastructure, it reduces single points of failure and creates competition in a sector dominated by a few corporations. Using open standards and open‑source designs encourages innovation and lowers barriers to entry. Embedding trust and payments into the network via blockchain enables users to pay, build credit and participate in the digital economy without traditional banks.  If successful, Spacecoin could provide a blueprint for intertwining decentralized connectivity and finance, particularly in regions where both are scarce. physically decentralizing open standards and open‑source designs trust and payments intertwining decentralized connectivity and finance Gluwa’s mission to drive global financial inclusion aligns with these goals. By integrating satellites and blockchain, the project offers a holistic solution: not just a signal in the sky but also a pathway to economic empowerment. As the World Bank emphasises, financial services enable individuals and businesses to invest in climate‑resilient infrastructure and recover from shocks.  With Spacecoin, a fisherman in India could not only receive storm warnings but also secure affordable financing for a new boat, pay for internet via micro‑transactions and build a credit profile recognized worldwide. drive global financial inclusion pathway to economic empowerment Conclusion: From Sky to Wallet The future of connectivity and finance may be written in orbit.  Spacecoin’s satellite‑blockchain hybrid is an audacious experiment, but it confronts two of humanity’s most pressing challenges: bringing billions online and giving them the means to participate in the global economy.  Bridging the digital divide is not only about building towers or launching satellites; it is about creating equitable access to information and opportunity.  If Spacecoin can prove that decentralized networks can deliver reliable service and fair economics, it could inspire a wave of real‑world DePIN applications—from energy grids to transportation—that empower communities rather than corporations. equitable access real‑world DePIN applications For readers, the promise of Spacecoin is a call to imagine a world where connectivity is a shared resource and financial inclusion is baked into the infrastructure.  Whether you’re a technologist, an investor, a policy maker or simply someone who cares about digital equity, the conversation has begun.  The next billion users are waiting—and their path to the internet might start not with a cable, but with a tiny satellite and a trustless ledger. The next billion users are waiting
