Flow control refers to the management of the rate and order in which transactions are processed and confirmed in a blockchain network. It ensures that the system can handle varying levels of transaction demand without becoming overloaded.When many users attempt to make transactions at once, the network can become congested. Flow control mechanisms help prioritize transactions, allowing more urgent or higher-fee transactions to be processed faster. This is crucial for maintaining efficiency and reducing wait times.Additionally, flow control can involve limiting the number of transactions sent in a given period, helping to stabilize network performance. It can also include methods for adjusting transaction fees based on network load, encouraging users to make reasonable fee offers.Overall, effective flow control improves user experience, enhances transaction reliability, and supports the long-term stability of the network’s infrastructure. By managing how transactions are entered and processed, it helps maintain the overall health and functionality of the system.
