Advanced topics
General
Every epoch, the top 21 validators ranked by stake are selected as committee members. Of those, the top 7 validators are selected as consensus nodes.
Rewards
Rewards come from newly issued tokens.
Fixed emissions of GAS. NEO token supply does not change. Every block, 5 GAS tokens gets issued. 40% goes to the delegators of the 7 consensus validators, 40% goes to the delegators of the 14 non-consensus validators, 10% goes to the 21 validators directly, and the remaining 10% goes to all NEO holders.
Factors that impact realized rewards.
GAS price. Since the reward is in a different currency, the price of GAS will affect realized rewards for stakers.
Risks
The protocol does not have any penalties or slashing.
