On September 1st, a large number of transactions took place on the BCH network, unlike any form of network stress test. It is also unusual for miners and nodes to spend hours dealing with backlogs. Because BCH is a large block, there should be no mempool problems (ie, the number of unconfirmed transactions). It has now returned to normal and there are very few transactions processed on the blockchain. One of the potential reasons for these peaks is the low-cost transaction form of broadcasting. It is unclear whether it will be a dust attack by default, although this is highly likely. Many of the transactions that caused the mempool backlog were sent at 7Satoshi or less per byte. In addition, the number of daily BCH transactions continues to decline, and this mempool issue may be to improve overall data.
