# Eclipse Attack

**Eclipse attack** is an attack method used in architectures where the network shares the workload with the nodes.

The purpose of this attack is to inactivate a particular node connection by providing more workload than its capacity and to seize the node connections.

For example, if a node has 8 connections and these connections accept up to 128 transactions, the attacker creates an overload of connections by sending more than 128 transactions to the focused node. As this overload will cause problems in the communication of all 8 connections with each other, the attacker exploits the vulnerability of the connections and takes control of the chain structure view.

Thanks to MetaAnthill, any artificial and natural traffic that can be experienced in the MetaChain network is suspended.

If (n+k) transactions arrive in the network above the node capacity, it suspends (n+k) transactions in packages in the form of n\*(Node Capacity), so as not to exceed the node capacity.

Thus, neither the large number of transactions executed by the attacker nor the large number of transactions occurring naturally can cause an overcapacity load on the nodes.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.metaverse-ico.net/whitepaper/attack-vectors-and-security/eclipse-attack.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
