Understand the options of the Ethereum command line: “Addnode” vs “connect”

When starting Bitcoin on a computer or using the command line interface, you can meet the options that seem similar, but serve different purposes. Two key options are “Addnode” and “Connect”, which can be used to manage connections with the Bitcoin junction. In this article we will examine the differences between these two options.

“Addnode” option

The “Addnode” option is used to add a new Bitcoin node to the network and attempt to maintain an open connection. After starting the “Bitcoind -addnode = IPcommand, it will connect to the specific IP address and start trying to determine a lasting connection. This option is necessary to maintain a reliable connection to the bitcoin network, but also consumes processor resources and bandwidth.

"Connect" option

On the other hand, the "Connect" option connects to the existing Bitcoin or Peer node without adding a new one. After launching the "Bitcoind -connect = IP command, it will set a connection to a specific IP address without creating a new node. This is useful when you want to join the network that already has available junctions to connect.

key differences

Here are the main differences between two options:

* Target : ‘Addnode’ creates and maintains a new node, while Connect ‘establishes an existing connection.

* Resource consumption : “Addnode” consumes processor resources and bandwidth, while trying to make a permanent connection. “Connect”, on the other hand, only requires basic system resources.

* Performance

: Establishing a new node can be slower than a connection with a new existing one, because it is a matter of creating a new block and a new network.

When to use each option

Here are some scenarios in which you need to use each option:

• When performing bitcoin for the first time or attempt to connect to the new network: ‘Addnode’

• When you want to join the existing network with available nodes: Connect

Example of use

To illustrate the difference, let’s complete two orders in the same system:

`Bash

$ Bitcoind -addnode = 10.0.0.1

creates and maintains a new node

$ Bitcoind -connect = 10.0.0.1

establishes an existing connection

''

In this example, "Bitcoind -addnode = 10.0.0.1 creates a new node in IP 10.0.0.1 and tries to determine a lasting connection. The performance “Bitcoind -connect = 10.0.0.1” is connected with the existing node without creating a new one.

To sum up, understanding the differences between “Addnode” and “Connect” is crucial for the effective management of the bitcoin network. By using the correct option for each scenario, you can optimize the consumption of resources, efficiency and general system stability.
