Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority – making it very difficult to corrupt or manipulate data once recorded. Blockchain therefore allows secure transactions to take place transparently and in an instant. The Smart Grid covers a broad spectrum of technologies that have helped bring about greater efficiency, visibility and intelligence. This evolution has facilitated the greater incorporation […]
