Consensus is the process of getting a bunch of computers to reach a consensus. By following a series of instructions known as a consensus protocol, computers can come to a consensus. POW, a trustworthy consensus process that is scalable, reliable, and decentralised, is used by QI. It offers a quick throughput and minimal latency. It uses little energy and doesn't need specialised computer hardware. It functions effectively in difficult conditions and is resistant to "51% attacks."
Consensus systems (networks of computers) can cooperate and maintain security thanks to consensus methods, often known as consensus protocols or consensus algorithms.
Consensus algorithms and protocols are frequently used interchangeably. Algorithms and protocols, however, differ from one another. A protocol is a set of guidelines outlined in a standard that controls how a system and all of its component elements work in unity. Algorithms are like detailed instructions on how to perform calculations or solve problems.
The establishment of consensus among database nodes, application servers, and other enterprise infrastructure has been accomplished for many years using these approaches. New consensus techniques have been developed in past years to enable crypto-economic systems, such QI Blockchain, to concur on the network's state.
A crypto-economic system's consensus process also aids in thwarting certain economic assaults. Theoretically, a hacker with 51% of the network's control may undermine consensus. Consensus procedures are made to prevent this "51% attack" from becoming successful. Different approaches have been developed to state this security issue in various ways.
