Hello.. Of course, here is a quick description.. Every account on the NEM blockchain is assigned an importance score. This score will influence how individual users can “harvest” the blockchain. One could say harvesting on the NEM blockchain is almost the same as what miners do on the Bitcoin blockchain. The objective is to add people’s transactions to the blockchain, in exchange for a small financial reward. As people’s importance score grows higher, they will have a better chance at getting these rewards. The Mininum score to begin delegated harvesting is 10,000 XEM
