Ethereum: Check the synchronization status of your full node
As a responsible user of the Ethereum network, it is important that your complete knot is fully synchronized. A fully synchronized node means that all nodes in the network are up to date and the data is up to date. In this article we will examine how to check whether your complete knot is fully synchronized with the command line tool from Bitcoin-Cli.
Why check the node synchronization status?
A fully synchronized node ensures:
- Network stability
: Knotes with Sync problems can lead to network instability and affect the access of other users.
- Data integrity : A fully synchronized node guarantees that all data is correct and complete.
- User Experience
: Disassemned nodes can cause delays or errors in the Ethereum Mainset.
Check the synchronization status of nodes with bitcoin-cli
Use the following command line tool to check your node’s synchronization status:
`Bash
Bitcoin -Coin -Q -T0 -url http: // localhost: 8332
Here is a breakdown of the options used:
-Q: rest mode to suppress the network edition.
-T0: Use TCP instead of UDP to get better error treatment and connection management.
--URL http: // localhost: 8332: Put the URL on the http server of your local node (e.g. ‘http: // localhost: 8332).
Understand the answer
If you carry out this command, you should see an answer that is similar:
{
“Knot”: [
{
“URL”: “
“Ethblocknumber”: “1234567890”,
“Ethhash”: “Abcde123e4567890123456789012345678901234567890abcdef”
}
],,
“Error”: zero,
“Status”: 1
}
`
This answer indicates that your local knot is connected to the Ethereum network and that all knots are synchronized.
Interpret the answer
Let us break down every field:
nodes: an array of objects that contain information about your local knot.
+ Each object has the following properties:
– URL: The URL of the HTTP server of your local node (e.g. ‘https: // mainnet.infura.io/v3/your_project_id).
-Ethblocknumber: The current Ethereum block number in hexadecimal format ( 1234567890).
-Ethhash: A hexadecimal representation of the blockchain data that is usually stored on your local knot.
- Error
: An optional field that indicates all the errors that occurred during the connection or the synchronization process. In this case it is "zero".
- Status`: The status of the synchronization process of your local node, which should be 1 for successful synchronization.
Troubleshoot
If you encounter problems when executing the command, try:
- Start your knot : A simple restart can fix connection problems.
- Update your node software : Make sure you use the latest version of the Ethereum client.
- Check network connectivity : Make sure your local computer has an active internet connection.
If you take these steps, you should be able to check whether your full node is fully synchronized and run smoothly in the Ethereum network.
