Proof of Importance (PoI) is the consensus algorithm used by the NEM blockchain. It builds on Proof of Stake (PoS) but adds more factors to decide who gets to add new blocks. Instead of only rewarding users who hold large amounts of coins, PoI also considers how active someone is on the network — including their recent transactions and who they interact with.
To qualify, an account needs at least 10,000 vested XEM (NEM’s native token). The more active and connected the account is, the higher its importance score, and the better its chances to “harvest” blocks and earn transaction fees. This system encourages real participation and keeps the network fair and energy-efficient.
