Exit nodes allow users to make requests to the wider internet and return those requests through a mixnet. However, forcing all Service Node operators to act as exit nodes could be detrimental, as acting as an exit node may expose the operator to legal risks, as users of the exit node may perform malicious activity whilst using it as a proxy. Opting-in as an exit node affords an operator double the reward of a normal relay when selected for a block reward. This incentive is provided to ensure that exit node operators have sufficient financial incentives to operate exit nodes.
