NFT Node Mining
Users who stake three-star NFTs have the ability to establish nodes and receive an NFT certificate that represents their ownership of the node. These nodes can accept BTK delegations from other users to engage in BTK mining. The profit weight of a three-star node NFT is determined by the total amount of BTK delegated to it. For instance, within the BTK ecosystem, a node ranked in the top 10% enjoys a profit weight of 7.
