✅ DAY 7/30

Transactions, Gas Fees & Reading the Blockchain (Etherscan)

Today I learned that every move in Web3 is public, traceable, and permanent.
No hiding. No guessing.
Just math + code doing their thing.


🔁 What Is a Blockchain Transaction?

A transaction is not just “sending money”. It can be:
Sending crypto
Minting an NFT
Swapping tokens
Calling a smart contract function
A transaction is basically:

“I want the blockchain to update its state.”

⛽ Gas Fees (Why You Pay Them)
Blockchains like Ethereum don’t run for free.
Gas fees pay for:
•Computing power
•Network security
•Validator work
You pay gas in ETH, even if you’re sending another token.
Why Gas Fees Change
Gas fees depend on:
•Network congestion
•Complexity of the transaction
•Demand vs space in blocks
•High traffic = higher gas.
That’s why sending ETH during hype can be expensive 💀

🧱 What Happens When You Send a Transaction?
- You click “Confirm” in your wallet
>Wallet signs the transaction with your private key
>Transaction goes to the mempool (waiting area)
>Validators pick it up
It gets added to a block

Blockchain state updates
Once confirmed:
❌ Can’t cancel
❌ Can’t reverse


🔍 What Is Etherscan?
Etherscan is a blockchain explorer.
It lets you:
-Track transactions
-View wallet balances
-Inspect smart contracts
-See gas fees
-Verify if a tx succeeded or failed
Basically: Google for Ethereum

📄 Reading a Transaction (Simple Breakdown)
When you open a tx on Etherscan, you’ll see:
•TX Hash
•Unique ID of the transaction
Status
•Success / Failed / Pending
•From / To
•Sender and receiver addresses
•Value
•Amount of ETH transferred
•Gas Used & Gas Price
•Cost of execution
•Block
•Which block it was included in
This is how you verify nothing is fake.
❌ Failed Transactions
A failed tx still:
•Uses gas
>Costs money
>Changes nothing
}}}Reasons for failure:
~Not enough gas
~Contract condition failed
~Slippage issues
Painful lesson everyone learns once 😭

🧠 Big Realization Today
In Web3:
There’s no “trust me bro”
Everything is verifiable
Anyone can audit anything
You don’t trust people. You verify transactions.
