🪙Blockchain for Beginners

✅ 30-Second Summary

  • Blockchain → A shared ledger where multiple computers store the same transaction records together

  • Wallet → Looks like an app that holds coins, but actually manages the keys that let you move your assets

  • Address → Your wallet’s receiving address → Think of it like a mailbox address

  • Transaction → A recorded action such as sending, swapping, or purchasing

  • Gas Fee (Network Fee) → A processing fee paid to the network to handle transactions

1️⃣ What Is a Blockchain?

A blockchain stores transaction records in groups called blocks, and keeps copies of those records in multiple places at the same time.

Because of this, once something is recorded, it’s very difficult to secretly change later.

👉 That’s why you can reliably verify who owns what.

2️⃣ The Network Used by EXTOCIUM

BNB Smart Chain (BSC, BNB Chain)

EXTOCIUM runs on the BNB Smart Chain blockchain network.

  • In wallets or apps, it may still be displayed as BSC.

  • Its former name was Binance Smart Chain.

📌 What matters most is this:

EXTOCIUM follows the rules of BNB Smart Chain, regardless of the name.

3️⃣ Why Do We Need Gas Fees?

On a blockchain, actions like:

  • Sending tokens

  • Swapping assets

  • Buying NFTs

all require the network to process them.

The cost of that processing is called a gas fee. (Think of it like a delivery or handling fee.)

On BNB Smart Chain, gas fees are paid in BNB.

4️⃣ What’s the Difference Between Tokens and NFTs?

🪙 Token

Tokens are fungible, like cash. One unit is interchangeable with another.

Example: 1 XTO is the same as any other 1 XTO.

※ The exchange value of XTO (to KRW, USD, etc.) can change, just like an exchange rate.

🖼️ NFT (Non-Fungible Token)

  • Each one is unique (like a limited-edition card)

  • Has a unique ID (Token ID)

  • Examples: NFT Heroes, NFT Weapons

That’s why NFTs are used as proof of ownership — “this one is truly mine.”

5️⃣ How Are NFTs Created?

1️⃣ A predefined rule set (smart contract) already exists 2️⃣ Someone requests an NFT to be issued 3️⃣ A unique ID is created 4️⃣ Ownership of that ID is recorded to a wallet address

All future transfers are also permanently recorded on the blockchain.

6️⃣ Why Use BNB Smart Chain?

Simply put:

  • It supports smart contracts

  • It works well with Ethereum-style wallets

  • It’s designed for fast processing and low fees

👉 It’s not about which chain is “better,” but which rules the game is built on.

7️⃣ The Safest Way to Avoid Fake NFTs

There are many fake tokens and NFTs with similar names.

The most reliable method is one thing: 👉 Search for EXTOCIUM NFTs

On BNB Smart Chain, you can verify official addresses and transaction history using BscScan.

8️⃣ What to Check on BscScan

① Transaction Hash

  • A unique ID for each transaction

  • Used to check success or failure

② Wallet Address

  • Shows which wallet owns which assets

③ Contract Address

  • The official source of a token or NFT

  • This is where security begins

9️⃣ How Do the Game Database and Blockchain Work Together?

  • Blockchain → Records who owns which NFTs

  • Game Database → Handles fast game processes like combat, progression, and inventory

Because of this, sometimes:

  • The blockchain transaction is complete

  • But the game screen updates later

👉 This is why it appears in Common Wallet Issues.

✅ After Reading This Page, You Will:

  • Know whether your network is BNB Smart Chain (BSC)

  • Understand the difference between tokens and NFTs

  • Be able to check issues directly using BscScan
