# 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.
