Spacecoin reveals blockchain network plans for space economy

Spacecoin XYZ, a blockchain satellite startup, has unveiled plans to launch a decentralised blockchain network in outer space, which it believes will form the foundation of an interstellar “space economy.” 

Announced in its November 1 Blue Paper, Spacecoin aims to establish a decentralised physical infrastructure network (DePIN) in space, using nanosatellites to enable a blockchain system independent of Earth. 

According to co-founder Daniel Bar, this network could become a permanent platform for transactions and commerce beyond our planet, enabling what he calls a "native space economy." 

Bar emphasised that preserving blockchain integrity beyond Earth could be crucial in cases of global conflict. 

“In the undesirable case that we have some kind of nuclear conflict or armageddon scenario, it's important to safeguard the future of blockchains,” he stated, adding that the network could serve as a safeguard for free market principles beyond state control. 

Spacecoin’s system includes a two-tier network structure, with a layer-1 blockchain—referred to as the “Celestial Chain”—deployed in space and a layer-2, Earth-based component called the “Uncelestial” network. 

The Celestial Chain acts as the authoritative ledger, designed to maintain an immutable record that could outlast Earth-based infrastructure. 

This design provides reliability for space-based operations, even during brief communication delays between satellites and Earth. 

Spacecoin has so far launched three satellites for testing in partnership with Aptos Orbital. 

Dahlia Malki, a professor of computer science advising Spacecoin, explained that the space-based network aims to support high-security applications, including secure data storage and a marketplace for "celestial services." 

She highlighted that tampering with satellite hardware is nearly impossible, unlike Earth-bound data centers. 

As the orbit around Earth becomes increasingly populated with services like Starlink, Malki noted that a decentralised blockchain network in space could support trade, payments, and contracts independently of Earth-based infrastructure. 

“To do this properly, you need a decentralised infrastructure that nobody controls,” Malki added, envisioning a future where the space economy grows parallel to humanity’s ventures beyond Earth.
