Blockchain will be a total game-changer if implemented in our defence acquisition system. By using blockchain technology teams building decentralised projects can take advantage of its most valuable strength – the ability to reach a shared truth that everyone agrees on without intermediaries or a centralised authority. The chain works as an immutable digital ledger. It is not possible to modify any block without changing the entire chain, this makes it highly valuable in what is often, a highly contested and complex defence domain.
