Event-Driven Layer Synchronization refers to a method used to ensure that different layers of a blockchain network remain in sync with each other based on specific events or actions. In most blockchain architectures, there are multiple layers, such as the base layer (which handles core transactions) and additional layers (like layer two solutions) that facilitate faster transactions or specific functionalities.This synchronization occurs when certain triggers or events happen, such as a transaction being confirmed or a smart contract being executed. Instead of constantly checking for updates, the system responds to these events, which optimizes performance and reduces unnecessary data processing.For instance, when a transaction is completed on the main layer, the event can automatically notify the secondary layer to update its records accordingly. This method enhances efficiency and reduces latency, making the overall system more responsive and reliable. By focusing on events rather than continuous monitoring, layer synchronization can better handle a high volume of transactions while ensuring data consistency across different layers.
