Answer: Tezos is a unique proof-of-stake blockchain that does not require users to lock up their stake in order to participate in the network. Instead, users are able to delegate their stake to a validator node or baker, allowing them to earn rewards for their contribution to the network without having to actively participate in the consensus process. This makes Tezos an attractive option for users who want to earn passive income from their holdings without having to commit to a long-term staking agreement.
