Spacecoin and the Midnight Foundation will explore a privacy-first messaging app over decentralised satellite internet and ZK proofs.
Spacecoin has announced a partnership with the Midnight Foundation to explore the development of a private, peer-to-peer messaging application built on decentralised satellite infrastructure and enhanced with zero-knowledge (ZK) proof technology.
The collaboration will examine how programmable cryptographic privacy can be applied to messaging systems operating beyond traditional internet infrastructure, aiming to eliminate content surveillance and metadata collection while reducing reliance on centralised networks that can be monitored, censored, or shut down.
The proposed architecture combines Spacecoin’s low-Earth orbit small satellites and blockchain protocol, described as coordinating the satellite network through smart contracts and removing central control points, with Midnight’s selective disclosure through ZK proofs. This would allow users to prove authorisation to communicate without revealing identity, location, or communication patterns, while also protecting transaction metadata.
The system is intended to be end-to-end encrypted with no server intermediaries, censorship-resistant at the infrastructure level, and resilient geographically, working anywhere with satellite coverage even when terrestrial networks are compromised.
Fahmi Syed, President, Midnight Foundation, said: “Privacy is not a feature or a privilege — it is a fundamental human right. To protect this right, we need to think beyond the application layer. If the underlying infrastructure itself is exploitable, true privacy does not exist.”
Tae Oh, Founder, Spacecoin, said: “Private messaging solves one problem. But the infrastructure we’re exploring to build together solves many. Once you can communicate privately over our satellite network, you can transact and access information privately.”
The combined infrastructure could extend to other privacy-critical applications, including private financial transactions, confidential healthcare communications in remote regions, and secure coordination for journalists and activists.
