A16z analysts pointed out that transaction processing speed is no longer the main criterion for evaluating the feasibility of blockchain, and the predictability of transaction processing during high load and failure periods is more critical. In the past five years, the mainstream blockchain throughput has increased from 25 transactions per second to over 3400 transactions per second, with some blockchains reaching tens of thousands of transactions, but the speed cannot inform traders when transactions will be processed. A one second delay is unacceptable in a volatile market, and a delay in order cancellation can lead to others trading at outdated prices, causing market makers to widen spreads and harm participants. A16z proposes the concept of "strong chain quality" to ensure that users submit orders without relying on a single operator, and to ensure that transactions are included immediately upon arrival.
