# Node Upgrade Activities

There are many valid activities to upgrade a Node. All follow a common principle: **Boost Multipliers are time-limited multipliers applied to Mining Rate, not FC added directly to the account**.

Node-upgrade activities fall into two groups. The first group is the core connection activities: Peer Meet, Trust Circle, Network Expansion, Anchor Node, and Knowledge Proof (Sections 4.4.1 to 4.4.5). The second group is three additional upgrade mechanisms that run in parallel and stack with the first group: Node Activation, Top Contributors Ranking, and the Node Tier System (Sections 4.4.6 to 4.4.8). Every Boost Multiplier from every mechanism accumulates into the value B in the mining formula in Section 4.2.
