# BLOCKCHAIN

## WAAT is on Blockchains

**WAAT Games** aims to protect its art, entertain its audience, and educate newcomers about the fundamentals of blockchain technology.\
Bringing communities together across blockchains is a core value of WAAT.

All blockchains generally follow three key principles: **decentralization**, **security**, and **scalability**. WAAT Games will operate on multiple blockchains to raise awareness about these differences among newcomers.

By using NFT technology and blockchain-based application like **Vault3.io** on **Cardano**, WAAT Games will share exclusive content with a restricted community.\
**Part One**, WAATittyMatrix, is already available.

## What is blockchain?

**Blockchain** is a decentralized digital system that records and verifies information in a secure, transparent, and tamper-proof way.

It works like a public ledger where data is stored in blocks, then linked together chronologically to form a **chain**. Once a block is added, it cannot be modified ; ensuring integrity and traceability.

Key features include:

* **Transparency**: All data is visible and verifiable by the network
* **Security**: Information is protected through cryptography
* **Decentralization**: No central authority controls the system
* **Ownership**: Users can hold and manage digital assets directly

Blockchain enables applications such as **cryptocurrencies**, **NFTs**, and **smart contracts**, and forms the technological backbone of **Web3** ; the next generation of the internet based on user ownership and trustless interactions.
