STAKE Reward Mechanics

STAKE used for staking, rewards are distributed in STAKE, xDai and EXIT

This is a proposed implementation. xDai Validators will vote to upgrade to dPOS and STAKE.

When the xDai POSDAO protocol starts, validator candidates and delegators place STAKE into the protocol. When validators are selected for a staking epoch, the amount of STAKE placed determines the corresponding amount of STAKE minted and distributed at the end of a staking epoch. The emission rate is determined through a risk assessment and community input. The current target is ~15% APR.

STAKE rewards also come from bridge fees assessed when users remove STAKE from the protocol (move it from the xDai chain to the Ethereum Mainnet).

STAKE can move in either direction on the bridge. Fees are assessed when transferring from xDai to Eth.

Additional Rewards

STAKE makes up the largest percentage of the staking incentive. Stakers also receive additional rewards in the form of xDai and EXIT.

  • xDai rewards. Paid to stakers from interest accumulated from locked CHAI. When users convert DAI or SAI into xDAI, it is initially locked as DAI in the bridge. This locked DAI is then converted to CHAI, which earns interest on the converted amount. The interest earned during a staking epoch is distributed to stakers at the end of the epoch.

  • EXIT rewards. EXIT is an exploratory virtual stable currency. It's stable value is backed by soft ETH. The face value of EXIT is stable, and the market determines the purchasing power of this synthetic reward token. EXIT may be incorporated at the beginning of the protocol or at a later date.
