Yes, Tezos secures its network by utilizing a proof of stake consensus mechanism. This mechanism allows bakers to stake their funds to validate blocks and earn rewards for their efforts. Bakers must have a minimum amount of funds staked in order to be eligible to validate blocks, and the more funds they stake, the higher the rewards they can earn.
