The key difference between Tezos and other projects like Ethereum or EOS, is that Tezos wants to drive innovation and prevent the split of its blockchain by implementing clever community-led governance mechanisms. This means that decentralised consensus - e.g. to agree on which features should be incorporated in the blockchain - is not completed by a management or development team. Instead, every stakeholder who owns XTZ is able to approve or disapprove amendments to its own protocol. To earn block rewards and be able to vote, stakeholders may choose to delegate their XTZ. Tezos calls this approach “Liquid Proof-of-Stake”, combining the concepts of liquid democracy with a Proof-of-Stake consensus mechanism.
