Securing Conversations: Understanding Blockchain for Communication

In the field of Risk Management, I frequently address inquiries concerning secure communication and the potential for spyware on compromised devices. My clients generally seek answers to two primary concerns: Has my device been compromised? What is the most secure form of communication?

To verify whether a device is free from advanced spyware, a forensic investigation of the target device is essential. This process involves assessing the sophistication of the potential attacker and understanding their motives. It requires examining the binary data of the device bit by bit, where we look for the most sophisticated attack vectors known today. When it comes to ensuring secure communication, our approach balances security with usability. Even the most secure device becomes impractical if the process is too complex or too long. Therefore, we tailor a balance suited to each specific case. For example, when using communication apps that store data in potentially risky jurisdictions, we consider relocating the data to a neutral country like Switzerland, enhancing both security and compliance.

Communication Decentralisation

A more advanced approach involves adopting blockchain messaging, which distributes encrypted data across multiple nodes, a fundamental aspect of blockchain decentralisation. This method ensures that messages are not confined to a single server under one entity’s control. Instead, they are scattered across a network of computers, significantly complicating any attempts by malicious actors or governments to compromise the system.

No Central Authority

WhatsApp is a popular platform with servers located in California, USA, and must comply with the privacy laws of that region. This means that communications that occur worldwide are subject to US privacy laws. However, blockchain communication eliminates this regional dependency, ensuring that user data is not constrained by the jurisdictional limits of any single country. Blockchain communication operates without a central authority. The absence of centralised control reduces the risk of censorship and tampering by the service provider, thus improving privacy and security for users who require unimpeded communication.

Resistance to Censorship

Blockchain’s decentralised nature inherently resists censorship. With no single authority able to block or remove messages and accounts, blockchain messaging becomes a useful tool when introduced into oppressive territories.

Despite ongoing challenges, the advantages of enhanced communication privacy and security continue to develop, and innovative blockchain-based messaging applications continue to push boundaries. At this developing stage, however, they may be perceived as threats to national security by governments in the short term, potentially leading to regulatory challenges within blockchain communication.
