Vitalik Buterin has addressed community discussions regarding the waiting time for Ethereum staking withdrawals, emphasizing that staking should involve some friction akin to soldiers fulfilling their duty to protect the blockchain. He noted that without such friction, the chain's credibility with nodes that are not frequently online could be compromised. Buterin also mentioned that there is room for optimization in the current staking queue design. According to the Ethereum Validator Queue, the current exit queue for Ethereum validators holds 2,497,293 ETH, with an estimated waiting time of 43 days and 9 hours. Meanwhile, the entry queue has 466,560 ETH, with an expected wait of 8 days and 2 hours.
