The Bitcoin blockchain is a transparent, decentralized ledger that records every transaction ever made on the network. But how do you actually view this data? Enter the Bitcoin block explorer — an essential tool for anyone using or exploring the world of Bitcoin. This guide will walk you through everything you need to know about using a block explorer, from finding your transaction ID to understanding confirmations and beyond.
Whether you're tracking a recent payment, verifying receipt of funds, or simply curious about how blockchain technology works, a block explorer puts all the information at your fingertips.
What Is a Bitcoin Block Explorer?
A Bitcoin block explorer is an online tool that functions like a search engine for the Bitcoin blockchain. It allows users to look up real-time and historical data about blocks, transactions, wallet addresses, and network activity.
By entering a transaction ID (TXID), Bitcoin address, or block number, you can retrieve detailed information about:
- The status of a transaction
- How many confirmations it has
- The amount transferred
- Timestamps and fees
- Sender and receiver addresses
This transparency is one of the core principles of blockchain — anyone can verify transactions without relying on a central authority.

How to Use a Bitcoin Block Explorer
Using a block explorer is simple and requires no technical expertise.
- Go to any trusted Bitcoin block explorer (such as mempool.space or other public explorers).
In the search bar, paste one of the following:
- A transaction ID (TXID)
- A Bitcoin wallet address
- A block height or hash
The explorer will instantly return relevant data based on your input.
For example:
- Searching a TXID shows details about a specific transaction.
- Searching an address reveals its full transaction history and current balance.
- Searching a block displays all transactions included in that block, along with mining details.
This functionality makes block explorers indispensable for verifying payments, debugging failed transfers, and analyzing network trends.
Where to Find Your Bitcoin Transaction ID
Your transaction ID (TXID) is a unique 64-character alphanumeric string that identifies your Bitcoin transaction on the blockchain.
You can usually find it in your wallet app after sending or receiving BTC. Here’s how:
- Open your Bitcoin wallet (e.g., Bitcoin.com Wallet)
- Navigate to your transaction history
- Tap on the specific BTC transaction
- Look for "Transaction ID," "TXID," or "View on Blockchain"
- Copy the string and paste it into any block explorer
Once entered, you’ll see live updates on confirmation status and network propagation.
How to Locate Your Bitcoin Address
To receive Bitcoin, you must share your public Bitcoin address — a string of letters and numbers starting with “1,” “3,” or “bc1.”
Here’s how to find it in most wallets:
- Open your wallet app
- Tap Receive
- Select Bitcoin (BTC)
- Your address will appear — copy it or share the QR code
You can then paste this address into a block explorer to check incoming transactions or monitor your balance publicly.
Remember: Your Bitcoin address is safe to share. However, for privacy reasons, it's best practice to use a new address for each incoming transaction.
What Information Do Bitcoin Block Explorers Display?
Depending on what you search, block explorers provide rich, detailed insights.
When Searching a Transaction ID:
- Transaction hash (TXID)
- Sending and receiving addresses
- Amount sent
- Network fee (in sat/vB or total BTC)
- Confirmation count
- Block height where it was recorded
- Timestamp of inclusion
You’ll also see whether the transaction is pending or confirmed — crucial for merchants and traders.
When Searching a Wallet Address:
- Total received and sent amounts
- Current balance
- Full list of incoming and outgoing transactions
- Number of transactions associated with the address
This data helps track portfolio movements, audit business payments, or investigate suspicious activity.

Understanding Confirmations in Blockchain
A confirmation means that a transaction has been validated and included in a block on the blockchain.
Here’s how it works:
- When you send Bitcoin, the transaction enters the mempool (a holding area for unconfirmed transactions).
- Miners select transactions based on fees and include them in the next available block.
- Once added to a block, the transaction receives its first confirmation.
- Each subsequent block added to the chain increases the confirmation count.
Why does this matter?
Each additional confirmation makes the transaction more secure. Reversing it would require re-mining that block and all following blocks — a computationally impossible task under normal conditions.
| General Confirmation Guidelines |
|---|
| 1–2 confirmations: Suitable for small purchases |
| 3–6 confirmations: Recommended for larger transactions |
| 6+ confirmations: Considered irreversible for Bitcoin |
On average, a new block is mined every 10 minutes on the Bitcoin network. So, six confirmations typically take about one hour.
Network congestion and low transaction fees can delay confirmations. Using dynamic fee estimators in your wallet can help prioritize faster processing.
Which Blockchains Can You Explore?
While this guide focuses on Bitcoin, block explorers exist for nearly every major blockchain network.
Each blockchain maintains its own independent ledger, so you must use the correct explorer for the network involved.
Common examples include:
- Bitcoin (BTC) – Use Bitcoin-specific explorers
- Ethereum (ETH) – Requires Ethereum-compatible explorers
- Litecoin (LTC), Dogecoin (DOGE), Bitcoin Cash (BCH) – Each has dedicated tools
- Smart contract chains (e.g., BSC, Polygon, Solana) – Have their own explorers
Always ensure you’re using the right explorer for the blockchain in question — searching a BSC transaction on a Bitcoin explorer won’t yield results.

Frequently Asked Questions (FAQ)
Q: Is using a block explorer free?
A: Yes — all major block explorers are free to use. No account or login is required.
Q: Can I track someone else’s Bitcoin transactions?
A: Yes, if you have their public address or TXID. All Bitcoin transactions are public and transparent.
Q: Does checking a transaction on a block explorer affect its speed?
A: No — viewing data doesn’t impact network processing. Confirmations depend only on miner activity and fees.
Q: Can I reverse a confirmed transaction?
A: No — once confirmed, especially after multiple blocks, Bitcoin transactions are irreversible.
Q: Why does my transaction show “unconfirmed” for hours?
A: Low fees or high network congestion may delay confirmation. Some explorers allow fee bumping via Replace-by-Fee (RBF).
Q: Are there privacy risks when using block explorers?
A: While addresses aren’t directly tied to identities, repeated use of the same address can enable tracking. Use new addresses regularly for better privacy.
