Proof of Stake (PoS) is a system of matching algorithms for public blockchains that depend on the economic share of the validator in the network. In practice, this means that this system will keep a set of validators running safely, which will be rewarded based on the amount of ETHs bet. For entering the ETH and confirming the correct blocks, you will be rewarded with another ETH through the interest rate for the entire network and you will receive part of the fees for network transactions. The minimum deposit will be 32 ETH. Sufficient technical performance of the computer and a stable internet connection are assumed. Validator - a participant in the solution of an algorithm that has passed at least a minimum deposit of 32 ETH. The key to proper validation is to ensure a constant online mode for the purpose of constant block approval and thus ensuring network security. Therefore, if your validator client goes offline at any time, your deposit is automatically fined to support the availability of validators.
