Staking is the primary value accrual strategy of IND. Stakers stake their IND on the Infinity website to earn rebase rewards. The rebase rewards come from the proceeds from bond sales, and can vary based on the number of IND staked in the protocol and the reward rate set by monetary policy.
Staking is a passive, long-term strategy. The increase in your stake of IND translates into a constantly falling cost basis converging on zero. This means even if the market price of IND drops below your initial purchase price, given a long enough staking period, the increase in your staked IND balance should eventually outpace the fall in price.
When you stake, you lock IND and receive an equal amount of sIND. Your sIND balance rebases automatically at the end of every epoch. sIND is transferable too.
When you unstake, you return sIND and receive an equal amount of IND. Unstaking means the user will forfeit the upcoming rebase reward. Note that the forfeited reward is only applicable to the unstaked amount; the remaining staked IND (if any) will continue to receive rebase rewards.
