According to @jih2nn, the interaction between execution payload release and IL (transaction list) building on Ethereum can occur independently, as the IL is simply a list of transactions without strict sequencing requirements. This means that execution payloads can be released before the IL is built, providing greater flexibility for validators and potentially reducing block production latency. For traders, this improved timing mechanism may lead to faster transaction confirmations and enhance overall network efficiency, which could impact trading strategies and short-term market liquidity on Ethereum (ETH).
