Understand how Ethereum nodes communicate with each other

The huge and decentralized Ethereum blockchain network play a crucial role in facilitating communication. In this article, we will look at the process by which the node communicates with other nodes to call information, such as non -approval of the transaction sentence (UTXO) or the longest chain.

Ethereum Network Report

The Ethereum network is based on a peer protocol by which the node can obtain and exchange data. Each network node acts both as a customer and as a server, and is based on his colleagues for information and services.

How to share information

To share information with other nodes, the node begins to link to several other nodes using the process called “Network Discovery”. If two or more nodes are connected, you can start a conversation with the Ethereum protocol. This conversation is proposed by one message sent to the other by one node called “ping” (short peer interface).

Ping News structure

Ping message consists of several components:

1
Network -id : Clear network identification.

• Knot -id : Recognition of the Request Node.

3
Requirement : A team or query indicating which information is requested, eg. B. UTXO or chain information.

Requirements

Ethereum has several types of investigation:

1
Get UTXO : Call several unconfirmed transactions (UTXO) from Blockchain.

• Get the longest circuit : Call the longest -valid block -Hash and related time stamp shows the latest approved block on the network.

Answer mechanism

If any request node sends a ping message to other nodes, he answers with his ping messages containing information about himself, eg. B. Your network -id and its node -id. After that, the reactive nodes launch new conversations with the demand nodes and repeat this process until the agreement is reached or the connection is lost.

Network Opening Process

The network recognition process includes several actions:

1
Initial Pings : The first ping message from the node begins conversation with other nodes.

• Answer Income : Other nodes answer the original ping message and provide information about yourself and your network.

3
Talk loop : The Requester Node continues to send ping messages until the agreement is reached or the connection is lost.

In summary, the Ethereum nodes communicate with each other through a ping, answer and conversation loop process so you can exchange information and connect to a huge and decentralized network.
