A proof-of-work consensus mechanism is being used by QI. As a result, anyone wishing to add new blocks to the chain must first crack a challenging puzzle that calls for a lot of processing power. By using computing resources, you can use the problem to "show" that you have finished the "work.". Mining is the practice of doing something. Mining is normally done through brute force trial and error; however, with QIE, adding a block successfully is rewarded.
