BNB API method that returns an object with information about the current synchronization status of the node, or false
if the node is fully synced. This method can track the progress of a node's synchronization with the Ethereum blockchain. The returned object contains data such as the starting block, current block, and highest block of the node, allowing developers to monitor and estimate the time remaining for the node to sync fully.

Response
result
— the boolean valuefalse
when not syncing or a JSON object when syncing:startingBlock

Use case
The eth_syncing
method on Ethereum can be useful for developers building applications that interact with the Ethereum blockchain. For example, you may want to provide feedback to your application's user about the status of the Ethereum node the application is connecting to.
