# Similarityscan

Similarityscan is a software tool that helps users identify the degree of similarity on any given smart contract against a database of popular smart contracts. This tool is particularly useful for investors who want to check if the project they have invested in is unique or if it has been copied.

Similarity Scan normally determines how similar two source codes are by looking for characters or phrases from one contract in the other. Token comparison and commonality detection are steps in this process. This process involves comparing the tokens, which are the basic building blocks of code, and identifying the common ones.

Cyberscope’s [Similarityscan](https://www.cyberscope.io/similarityscan) tool can perform a side-by-side comparison of source codes. The tool checks for similarities by comparing the code that is being checked to the existing codes in its database. This is a crucial factor in ensuring the security and reliability of a smart contract.

It is crucial to remember that a smart contract still has to be extensively inspected to verify its security, even if it is very close to a reliable implementation.

## 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.cyberscope.io/tools/similarityscan.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.
