POSDAO Whitepaper
xDai runs on a new type of dPOS consensus called POSDAO.
Barinov, I., Arasev, V., Fackler, A., Komendantskiy, V., Gross, A., Kolotov, A. and Isakova, D. POSDAO: Proof of Stake Decentralized Autonomous Organization (April 29, 2019). Available at SSRN: https://ssrn.com/abstract=3368483 or http://dx.doi.org/10.2139/ssrn.3368483​
The public POSDAO staking app can be accessed here: https://blockscout.com/xdai/mainnet/validators​
POSDAO introduces the STAKE staking token and a new consensus model where individuals who own STAKE may become validators or may delegate their stake on current validators in order to protect the chain. Validators and delegators receive rewards in exchange for providing STAKE to secure the protocol.
