 ## Tezos uses proof of stake
 
-The proof-of-stake consensus model consensus model eliminates the need for high energy use, making it the "green" choice for blockchains. Instead of competing to achieve consensus as in proof-of-work models, Tezos nodes (called *bakers*) stake Tezos tokens to earn the right to create blocks and receive rewards. Users who want to participate without running a node themselves can delegate tokens to a baker for a share of the rewards. The bakers and delegators keep control of their tokens and can remove them at any time. Tezos's approach to consensus has been described as [Liquid Proof of Stake](https://medium.com/tezos/liquid-proof-of-stake-aec2f7ef1da7).

 The proof-of-stake model improves scalability and encourages incentive alignment. It also increases the cost of 51% attacks and avoids environmentally wasteful proof-of-work. Tezos launched in June 2018 as one of the first major proof-of-stake networks.
