In the previous two articles of The Journey of Bitcoin Transactions, we quickly explored the basic process of how transactions move from issuance to blockchain inclusion. Now, we'll apply that knowledge by learning to use a blockchain explorer to interpret the information contained in a transaction record.
What Is a Blockchain Explorer?
Just as we use web browsers like Chrome or Safari daily to browse various websites, a blockchain explorer serves a similar purpose—it's a practical tool for viewing transaction details recorded on a blockchain.
While Bitcoin has its own explorers, other cryptocurrencies, such as Ethereum, also have dedicated blockchain explorers. Today, we'll focus on Bitcoin. For those interested in Ethereum blockchain explorers, you can explore:

How to Use a Blockchain Explorer
Let’s take btc.com as an example and walk through its interface step by step. Simply enter one of the following into the search bar:
- Wallet Address
- Transaction ID (Tx ID)
- Block Height Number
- Block Hash Value
Common use cases include:
- Checking a specific transaction (using the Tx ID).
- Verifying an address’s balance.
What Information Can You Find in a Blockchain Explorer?
Case 1: Checking a Specific Transaction
For demonstration, let’s examine a random transaction with the ID: 9b9a91d56b1edc742b67809358b4c8faef4bc9a0fab3c7850287ce004e3286e7.
Key details include:
- Block Height (#599185): Represents the sequential order of blocks in the blockchain.
- Confirmations: After a transaction is first included in a block, it receives one confirmation. Each subsequent block adds another confirmation—six confirmations are typically considered irreversible.
- Timestamp: The exact time the transaction was added to the blockchain.
- Inputs & Outputs: Analogous to accounting’s debit (Input) and credit (Output) entries.
- Fee: The miner’s service charge—calculated as the difference between Input and Output amounts.
Case 2: Checking Address Balance
When querying an address, focus on:
- Balance: The current holdings.
- Tx Count: Total transactions linked to the address.
- Transaction History: A list of past transactions, including IDs and input/output details.
FAQ
1. Why are confirmations important?
Confirmations ensure transaction finality. Each added block reduces the risk of reversal, making six confirmations a standard for security.
2. How are transaction fees determined?
Fees depend on network congestion and transaction size. Higher fees incentivize miners to prioritize your transaction.
3. What is UTXO?
Unspent Transaction Output (UTXO) is Bitcoin’s model for tracking transaction chains—where outputs from one transaction become inputs for the next.
