Managing Cluster Membership

Adding New Nodes

• When new nodes join the network, they are added to existing clusters.

• The system ensures that the addition of new members maintains the required security thresholds.

Removing Nodes Safely

• If a node needs to be removed—due to maintenance, failure, or security concerns—the system carefully redistributes its key shares.

• This ensures that the integrity and security of the cluster remain intact even after changes in membership.
