# Transaction Weight Assignment

Transaction action weights are assigned through decentralized on-chain voting. An action is represented as a floating-point number between 1 and 10. The weight assigned to an action is constant for all users, regardless of their past actions. Transaction weight assignment to actions is performed by the Validation Layer of the Flex Node.

## Weight assignment

Transaction weights are assigned as follows:

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

```
GET https://flexecosystem.gitbook.io/flex-docs/protocol/flex-validator-nodes/getting-started/transaction-weight-assignment.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
