Proof of Importance (PoI) is a consensus mechanism used to validate transactions and secure networks, notably employed by NEM (New Economic Movement). Unlike Proof of Work, which requires significant computational power, PoI focuses on the importance of user activity and network participation.In PoI, a user’s importance score is calculated based on various factors, including the amount of cryptocurrency they hold, their transaction history, and their interactions within the network. This score determines the user’s influence in creating new blocks and validating transactions.The primary goal of PoI is to encourage active engagement. Users are incentivized to hold and use their coins rather than merely mining them. This approach fosters a healthier network ecosystem, as it prioritizes users who contribute positively and consistently.Overall, Proof of Importance promotes a balanced system that rewards meaningful participation while reducing the risks associated with centralization and malicious behavior.
