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.
