On the three major centralization issues of Ethereum. Firstly, there is a risk of centralization in Ethereum's BFT POS consensus mechanism. Unlike Bitcoin's POW, BFT POS is deterministic and non NP complete. Non NP complete problems can lead to predictable node behavior, easy manipulation, and potential centralization risks. Secondly, Ethereum's Account global state tree also faces centralization issues. All account information is stored in a global state tree, and anyone can track the transaction records of all accounts. There is a risk of privacy leakage, which contradicts the privacy protection requirements of "individual". Furthermore, the consensus of the control chain can arbitrarily change the data under any individual's account, that is, individual accounts and individual sovereignty are separated and fragmented. Finally, Ethereum's EVM computation also faces centralization issues. Due to its centralized consensus mechanism and account model, EVM computing also relies on a centralized node network, making it vulnerable to single point failures and attacks. In summary, Ethereum's BFT POS consensus, Account global state tree, and EVM computation all have centralization issues. This goes against the decentralized concept advocated by Bitcoin and also raises concerns about the development prospects of Ethereum in the "individual" distributed computing world.
