📚 CRYPTO 101 — ARTICLE #58: Transaction Hash là gì
When you send or receive cryptocurrency, every transaction is recorded on the blockchain.
But how do you track a specific transaction among thousands or even millions of others?
This is where the transaction hash becomes important.
A transaction hash is a unique string of characters that identifies a specific transaction on the blockchain.
It works like a digital receipt or tracking code.
Every transaction has its own hash, and no two transactions share the same one.
Here are the key ideas behind transaction hashes.
1️⃣ A unique identifier
Each transaction has its own hash that distinguishes it from all others.
2️⃣ Used to track transactions
You can use the hash to check the status of a transaction.
3️⃣ Created automatically
The blockchain generates the hash when the transaction is processed.
4️⃣ Cannot be changed
Once created, the transaction hash is permanent and cannot be modified.
A simple example can help explain this idea.
Imagine sending a package through a delivery service.
After sending it, you receive a tracking number.
You can use that number to check where the package is and whether it has been delivered.
A transaction hash works in the same way.
When you send crypto, you receive a hash that allows you to track the transaction on the blockchain.
For example, a transaction on Ethereum might look like a long string such as:
0x5f2c...9a8b
This string represents your transaction and can be used to view its details.
Transaction hashes are important because they provide transparency.
Anyone can verify a transaction using its hash without needing to trust a third party.
