Ethereum: How to set syncnode of a peer to true?

Setting the synchro of a peer on true

As an administrator or network developer, ensure that the Ethereum Testnet connection is correctly configured for synchronization with other nodes can be crucial to maintaining the consistency of data and prevent orphans. In this article, we will guide you through the process of setting the synchronization node of a peer on True on a testnet connection.

What is the synchronization node?

In Ethereum, a synchronization node
is a node that acts as an intermediary among other nodes in the network, inulating the data and ensuring that all the nodes are synchronized. When a client connects to a synchronization node, it can request information on other clients connected to the same node, including their addresses, services and last sending of TimesTamp.

Why set the synchronization node on True?

Set the synchronization node of a peer on True guarantees that:

• All nodes in the network are aware of mutual presence and connections.

• The data of each client are propagated through the network and made available for synchronization by other clients.

• The orphaned blocks, which can occur when a node disconnect or is linked, are removed from the network.

Passing-step guide

To set up the synchronization node of a peer on True on the testnet connection, follow these steps:

1.
Get information peer

First of all, you have to recover information on the peer with whom you want to synchronize. You can do it using the Getperinfo in the Ethereum console or through an API call command.

`Bash

Eth Console -Q Getpeerinfo

`

Replacewith the peer testnet address.

2

The Output from theGetperinfoCommand will contain a Json object containing various information on Peer, including its addresses and services.

Json

{

“Addr”: “172.20.61.111:63379”,

“Services”: “00000001”,

“Lastsend”: …

}

`

In this example:

• ADDRIS is the address of peer.

• Services indicates that this peer uses 0x services (e.g. ETH, Ether).

• Lastsend provides information on the last time this customer sent a message.

3.
Create synchronized knot

To set the peer synchronization node on True, it is necessary to create an instance of a syncnodeis class that connects to the testnet connection. You can use the following code as a starting point:

Javascript

Const Network = Requirements (‘Ehers’);

Const {Syncnode} = Requirements (‘./ Sync-Node.js’);

Async Main () {function

Const NetworkConfig = New Network.Web3.providers.httpprovider (‘

Const Client = New Network.Client (Networkconfig);

// Create an instance of the synchronization node

Const Syncnode = New Syncnode (client, ‘0x00000001’, 1); // Replace with your services

// Set the synchronization node on True

Syncnode.setsyncnode (True);

}

Main (). Catch ((error) => console.error (error));

`

Make sure you replace your_project_id with your Ethereum Testnet ID project.

4.
Update Peer

information

Finally, it is necessary to update the Peer information in the Json object obtained previously by setting up its field of service on 1 (or another valid service code). You can do it using a small Javascript function:

`Javascript

Setservices function (peerinfo) {

If (! Peerinfo.Services ||! Peerinfo.Services.includes (‘Eth’)) {

// Set the services on ETH, if not already present

peerinfo.services = [‘eth’];

}

return peerinfo;

}

// Update Peer information with the services set to 1

Const Updatedpeerinfo = Setservices ({… peerinfo});

Console.log (Updatopederinfo);

`

Conclusion

By following these steps and using theSyncnode` class, you can easily set the synchronization node of a peer on True on the Ethereum Testnet connection.
