SpaceChain is pioneering a revolutionary approach to digital security, using satellite technology to create secure, authenticated channels for digital transactions.

Why Security is Crucial in Digital Transactions

As the world of digital assets expands, secure communication and transaction verification are essential. In this space, it’s not just about key management—it's about ensuring that users can confidently verify each other’s identities.
 

For example, if Alice wants to send Bitcoin to Bob, she needs to know that Bob’s wallet address is accurate. This is true for any communication, including browsing a secure website.
 

On the web, security relies on Certificate Authorities (CAs), third-party organizations that issue certificates to ensure the legitimacy of websites.

Here’s a quick look at how that works:

But this system depends on secure CAs and isn’t always enough for higher-stakes transactions, like digital assets. Introducing SpaceChain’s satellite-based solution.
 

SpaceChain’s Solution with Satellite Technology

SpaceChain uses low Earth orbit (LEO) satellites to establish a new level of trust for digital transactions. 

The Core Components:

• LEO Satellite Constellation: Acts as the root of trust, similar to a CA on Earth.
• Handheld Terminals: Provide users with a secure communication device.
• Satellite Network: Ensures a secure, global link.
  
  How It Works:
  

Using satellites as a trust anchor means a stronger defense against cyber threats, as satellites are costly and complex to attack. This enhances security by making attacks both expensive and difficult.

Securing User Keys with SpaceChain’s Handheld Terminal

For users managing digital assets, it’s not enough to trust the other party; they also need to protect their own keys. For example, in a cryptocurrency wallet transaction, Alice must.....
