In order to participate in securing the network consensus, a node operator must stake a minimum required amount of FUSE tokens (currently set at 100,000 FUSE). Becoming a validator on Fuse is permissionless, meaning that a node operator just needs to satisfy certain technical requirements. The need to stake FUSE ensures that an entity cannot create multiple seemingly distinct validators without incurring a significant cost. Hence, the Sybil protection. Currently, the maximum number of validators on Fuse Network is 100.
