During the development of Ethereum, validators have left one after another: What causes this phenomenon?

Since mid-August 2024, the number of Ethereum validator exits has surged by 188%, with a total of 2.64 million ETH withdrawn, mainly due to changes in protocol upgrades and staking incentives. Despite this, Ethereum maintains more than $123 billion in stablecoins and $75 billion in DeFi assets, processing 24 million transactions across 870,000 validators and 13,600 nodes worldwide.
