Validators are responsible for the network's infrastructure and operation. They are in charge of creating new blocks, validating blocks, ensuring finality, and ultimately ensuring the network's security. They must be responsive at all times and maintain a secure, dependable infrastructure. Furthermore, validators require tokens to back them up, which encourages them to follow the rules because a portion of these tokens may be taken away otherwise (called slashing). Validators are compensated for their services with incentives priced in the native token of the underlying network (e.g. ICY on ICE and ICZ on Snow).
