The technology of Blockchain is most simply defined as a decentralised distributed leader recording the origin of a digital asset. The data on a blockchain is immutable by design, making it a legitimate disruptor in industries such as payments, cybersecurity, and healthcare. A Google Doc is a simple analogy for understanding blockchain technology. When we make a document and share it with a group of people, it is distributed rather than copied or transferred. This creates a decentralised distribution chain in which everyone has simultaneous access to the document. No one is locked out because they are awaiting changes from another party.
