A16z crypto analysis: The contradiction between blockchain censorship resistance and low latency

According to an article by a16z crypto researchers, there is a fundamental contradiction between the "censorship resistance" and "low latency" of blockchain. Any Byzantine Fault Tolerant (BFT) blockchain protocol with anti censorship capabilities requires at least 5 rounds of communication in cases where the validator exceeds 0.2 and may commit malicious acts, while traditional BFT consensus only requires a minimum of 3 rounds. To address the issue of block proposers reviewing transactions, Ethereum research FOCIL/EIP-7805, Solana research Constellation and MCP, both use validators to collect transaction "inclusion lists" in advance to ensure anti censorship. Transactions will be included in the block no later than 5 rounds of communication.
