What is PoI (Proof of Importance)?
Crypto Glossary Definition
A blockchain consensus algorithm first introduced by NEM. Proof of Importance is the mechanism that is used to determine which nodes are eligible to add a block to the blockchain (this process is known as 'harvesting' in NEM). It is different than Proof of Stake in that it factors one’s overall support of the network into account, not just the current moment in time. Vesting, transaction partners, number and size of transactions are all factors.
