Scenаriо: Ethereum, а prоminent blоckchаin platform, shifted from a Proof of Work (PoW) consensus method to Proof of Stake (PoS) with the introduction of Ethereum 2.0. In a Proof of Stake (PoS) system, validators, rather than miners, are tasked with protecting the network and confirming transactions. They are selected to validate blocks based on the quantity of cryptocurrency they stake as collateral. Alice, Bob, and Carol are players in the Proof of Stake process of Ethereum 2.0. The Ethereum network employs a staking pool in which individuals are randomly chosen to validate blocks, with the probability of selection being proportional to their staked amount.Alice has staked 100 ETH.Bob has staked 150 ETH, while Carol has staked 250 ETH.The aggregate stake in the network amounts to 500 ETH (100 ETH + 150 ETH + 250 ETH).At a specific moment, the network is designating a validator to propose a new block. 1. What is the probability that each participant (Alice, Bob, Carol) will be selected as the validator for the next block? 2. The Ethereum network is designed so that validators are rewarded for their work. For every block validated, the reward is 2 ETH, which is distributed proportionally to the validators based on their stake. Calculate the reward for each participant if they were selected as the validator.
