Bitcoin and other digital currencies utilize blockchain. Blockchain, in summary, is a collection of blocks. Within each block is a collection of transactions. Each computer (node) has the same list of blocks and transactions, which they can see as the blocks are filled with the transactions. While this is the traditional application experienced, there are other applications relevant to cybersecurity. As part of the blockchain technology, the nodes are responsible for decision-making. The blockchain technology may be used for this function in these systems. In adjusting the data flow, this is an option to increase the cybersecurity for a complete system. This addition to the cybersecurity system provides a clear benefit.
