Why Blockchain is becoming an integral part of Defence technologies across the globe

Blockchain is set to revolutionise historical practices in relation to security and communications throughout the entire modern military. With the opportunity to connect land, air, and sea vehicles through a centralised command-and-control system, the power of a networked military is clear.

However, this interconnected military in theory also opens itself up to higher risks and vulnerabilities in relation to cyber-security. For many military strategists and cyber-industry thought leaders, blockchain is the key for ensuring said security moving forwards.


In April of this Year, Defence sector giants, Lockheed Martin, announced that they would be integrating blockchain features into its military data systems to increase security in relation to data manipulation and control over network connected weapons systems.


Blockchain’s key attribute for the military is its distributed node system, allowing selected users access to differing layers of activity within a cryptographically sealed network. Blockchain builds on an ideology of dispersion, spreading multiple data nodes to ensure the loss of one node cannot bring down the whole system.

Although civilian applications of blockchain are currently in development, especially within the banking sector at present, it is estimated that military systems will need to be up to 10 times stronger in relation to security and encryption. The needs for this is clear when considering the possible applications of blockchain for the military, and the type of information and control that will be available through the network.

One example that is currently being explored is the use of blockchain to support on-field military communications between infantry, central command, and allies. Soldiers are currently capable of communicating through personal devices worn on their wrists. Blockchain would allow the military to keep this information in a specific, closed network, with commanding users capable of controlling access to said communications. In other words, a commander can easily relay messages to the entire support network of allies and staff, or to individual actors as per the nature of the information.


Following on from these beneficial uses and impact to the sector, many global military organisations are now exploring how this disruptive and exciting technology may best be integrated into their operational applications and support networks. In line with this, new funding and partnership opportunities are opening up for cyber-security companies that can prove their applicability and worth to the military in relation to blockchain.
