A Bold Step towards Blockchain in Space

The European Space Agency (ESA) has recently made headlines by awarding a grant of 60,000 euros (about $66,400) to SpaceChain, a startup on a mission to revolutionize the way we think about secure transactions in space. This grant, part of ESA’s “kick-start activities” fund, will aid SpaceChain’s efforts to commercially develop its innovative satellite-powered, multi-signature wallet.

What the Multi-Sig Wallet Is All About

So, what’s the deal with this multi-signature (multi-sig) wallet? In simple terms, it’s designed to enhance the security of digital currency transactions. Instead of relying on just one key, it requires two out of three private keys to authorize and complete transactions. This is akin to needing two keys out of a trio in a sci-fi vault—imagine the drama!

• One key is held by a satellite-based node.
• If communications fail, ground-based signatures come to the rescue, completing transactions seamlessly.
• SpaceChain’s approach provides a higher level of security crucial for decentralized finance (DeFi) solutions.

Securing the Future of Decentralized Finance

Speaking of security, SpaceChain’s co-founder and CEO, Zee Zheng, expressed the urgency of improving security in the fintech sector. “The fintech industry currently suffers from low levels of security in relation to the storage and transmission of digital currency,” he noted. Zheng argues that enhancing trust in these systems is vital if digital currency is to gain the same credibility as traditional banking.

Collaboration is Key

But SpaceChain isn’t flying solo on this venture. They’re teaming up with Deimos Space UK, bringing together expertise in:

• Flight systems
• Ground segment systems
• Space situational awareness
• Satellite navigation

With the combined force of these strengths, the project is set to soar—quite literally!

A Historical Perspective on Blockchain in Space

SpaceChain isn’t the first name to pioneer blockchain services in orbit. In December 2018, Blockstream made waves by expanding its satellite service to broadcast the Bitcoin (BTC) blockchain across Earth. The idea of Bitcoin relay satellites originally came from Jeff Garzik’s BitSat scheme back in 2014, which, unfortunately, never took off. Fast forward to February 2018, and SpaceChain made headlines by launching their first space-based blockchain node in cooperation with Qtum, solidifying their place in the cutting-edge fusion of blockchain and space technology.

Looking Ahead

This ESA grant is just the beginning for SpaceChain. With the potential for additional funding from ESA’s Business Applications and Space Solutions down the line, the future looks bright (or should we say, cosmic?) for this innovative venture.
