# Tezos blockchain

**Updated on 09/27** 

We are thinking about adopt Tezos blockchain.

Tezos is particularly known for its inexpensive transaction fees, formally verified smart contracts, and the minting of NFTs. These qualities are what makes Tezos the default platform for NFT creators.

Tezos prevails as the preferred place for creators to mint their NFTs also because of its energy efficiency. And this point is very important for us.

The top 10 coins using the least energy annually:

# Agent Instructions
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.fragment.technology/tech-architecture/backend/tezos-blockchain.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.
