# Blockchain Language Used in Kryptomon

## What is Blockchain? <a href="#what-is-blockchain" id="what-is-blockchain"></a>

A ***blockchain*** is a shared, immutable ledger that stores information such as recording transactions and tracking assets in digital format. The data is stored in a block, that forms a chain as the asset moves from place to place or ownership changes hands. No one can alter the block once it is recorded.

### **Gas & Fees**

Being a blockchain game, some transactions in Kryptomon require "gas" to be processed. Activities such as buying, breeding, or selling your Kryptomon will fail should you find yourself without enough **Matic** to pay as gas.

Since Kryptomon is running on the Polygon Network , the cryptocurrency you'll need for gas fees is known as **Matic** (ERC 20). Usually, gas fees are low even with higher traffic in the network.

### What is Cryptocurrency? <a href="#what-is-cryptocurrency" id="what-is-cryptocurrency"></a>

A ***cryptocurrency*** or ***crypto*** is a form of digital asset that uses cryptography to secure transactions. Most cryptocurrencies use decentralized networks based on blockchain technology to record transactions and issue new units.

### What is an NFT? <a href="#what-is-an-nft" id="what-is-an-nft"></a>

An ***NFT*** or ***Non-Fungible Token*** is a type of digital asset that can be verified using blockchain technology. An NFT using blockchain technology replaces the need for certificates of ownership. It marks the unique ownership of a product that you see online, like art, music, or in-game assets. It provides exclusive ownership of a property, making them unique collectibles.

## 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://academy.kryptomon.co/the-kryptomon-academy-1/getting-started/kryptomon-basics/blockchain-language-used-in-kryptomon.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.
