What Is a Blockchain Explorer?
A blockchain explorer is an online tool that allows you to view details about blocks, addresses, and transactions on a blockchain network. When you enter a blockchain address or transaction ID, the explorer will pull up all the details about that transaction, address, or block.
Blockchain explorers are useful for a few reasons:
•Looking up specific transactions. If you want to see the details of a transaction you made or received, like the amount sent, fees paid, and block confirmation, you can enter the transaction hash or ID into an explorer.
•Checking your wallet balance. By entering your wallet address into an explorer, you can view your current balance and transaction history. This is a good way to verify funds were received properly.
•Viewing blockchain data. Explorers provide an inside look at what’s happening on public blockchains. You can see metrics like hash rate, difficulty, block time, size, and more.
•Inspecting smart contracts. For blockchains like Ethereum that support smart contracts, explorers allow you to view the code and details of any contract. This transparency is important for security and trust.
•Researching blockchain applications. Explorers make it easy to look under the hood of any decentralized application (dApp) built on a public blockchain. You can analyze the smart contracts that power the app and see how they work.
There are many popular blockchain explorers out there for viewing data on blockchains like Bitcoin, Ethereum, Bitcoin Cash, and others. Different explorers have different features, so you may want to try a few to find one you like. In the end, blockchain explorers add an important layer of transparency and openness to public blockchains.
How Blockchain Explorers Work
Blockchain explorers are websites that allow you to explore the details of blockchain networks like Bitcoin, Ethereum, and Bitcoin Cash. They provide an easy way for you to look up transactions, view network stats, and more.
Blockchain explorers get their data from public blockchains. They access the blockchain protocol directly and parse the raw data into something readable. The explorers then organize the information into user-friendly web interfaces where you can search for transaction hashes, wallet addresses, block numbers and other identifiers.
Some of the most popular public blockchain explorers include Blockchain.com for Bitcoin, Etherscan for Ethereum, and Blockchair which supports many cryptocurrencies. Using any of these, you can enter a transaction hash, wallet address or block number and get details like:
- The number of confirmations for a transaction, indicating how securely it’s locked into the blockchain.
- The date, time and amount of the transaction.
- The sending and receiving wallet addresses involved.
- The mining fee paid.
- Any smart contract details or token transfers (for Ethereum transactions).
Blockchain explorers provide an essential window into the inner workings of public blockchains. They make the blockchains transparent and help build trust in the networks by allowing anyone to audit transactions and blocks. The explorers have become invaluable tools for developers, miners, traders, businesses and casual crypto users alike.

Looking Up Bitcoin Transactions
Once you have a Bitcoin wallet and some coins, you’ll eventually want to send and receive transactions. A blockchain explorer allows you to view details about Bitcoin transactions and blocks.
Find Your Transaction Hash
When you send Bitcoin, your wallet will provide you with a transaction hash, which is like a receipt for your transaction. Copy this hash and paste it into the search bar of a blockchain explorer like Blockchain.com, Blockcypher, or Blockchair. This will pull up details about your transaction including the amount sent, transaction fee, date and time, and the receiving address.
Check Your Wallet Balance
Most block explorers allow you to view the balance and transaction history of any Bitcoin wallet address. Just enter your wallet address into the explorer search bar to see how much BTC is stored there and a list of all incoming and outgoing transactions. This is useful to verify that transactions have been properly received and for reconciling transactions with your records.
View Details of Any Transaction
Blockchain explorers provide transparency into all Bitcoin transactions. If you have the transaction hash of any Bitcoin transaction, you can view its details. This includes things like the amount of BTC transacted, date and time, transaction fee, sending and receiving addresses, and the block the transaction was recorded in. You can see the flow of coins between addresses and use this information for compliance, audits, and investigations.
Track Unconfirmed Transactions
Sometimes Bitcoin transactions can take a while to confirm depending on the transaction fee and current network activity. Block explorers will show unconfirmed transactions that have not yet been recorded in a block. You can view details about the unconfirmed transaction and see its progress as it gets confirmed in a block. This allows you to track your transaction through the entire process from sending to confirmation.
In summary, blockchain explorers are useful tools for looking up details about Bitcoin transactions, wallet balances, blocks, and the overall blockchain network. They provide transparency into the flow of transactions which helps with record-keeping, auditing, and compliance. The top explorers are free to use and offer APIs for integrating blockchain data into your own apps and services.
Checking Ethereum Blockchain Data
The Ethereum block explorer allows anyone to easily look up, confirm and validate transactions on the Ethereum blockchain. Transactions
You can enter a transaction hash or address in the search bar to pull up details of any Ethereum transaction. This includes information like the sender, recipient, amount transferred, transaction fee, block number and timestamp. Checking your own transactions can give you peace of mind that your funds have been received or smart contract interactions have executed properly.
Blocks
Ethereum groups transactions into blocks, with each block building upon the previous one to form a chain. You can browse blocks to see all the transactions contained within, as well as the miner who validated the block. The block number shows you how many blocks have been added to the chain since the genesis block. Over time, you’ll notice the average block time of around 15 seconds.
Addresses
An Ethereum address, also known as an account, holds ether and is used to send and receive transactions. You can look up any address to view its balance, transaction history and smart contracts deployed from that address. Be very careful when entering your own address, as anyone can see your balance and transaction details.
Smart Contracts
If a transaction interacts with an Ethereum smart contract, you’ll be able to view details of the contract including its address, creator, bytecode, and Application Binary Interface or ABI. The ABI defines how to interact with the contract, so you can call its functions and see how it modifies storage. Exploring open source smart contracts is a great way to learn how to build your own dapps!
Tokens
In addition to ether, Ethereum is home to many crypto tokens issued via smart contracts. You can often find details of a token’s smart contract on its block explorer page, including total supply, decimals used and token holder balances. This allows you to verify a token is legitimate before purchasing any.
Checking the Ethereum blockchain explorer regularly is an easy way to gain valuable insight into how this innovative technology works in practice. You never know what interesting transactions, smart contracts or blocks you might stumble upon! So take the time to explore – your inner blockchain detective will thank you.
Using Blockchain Lookup for Other Cryptos
Once you get the hang of using a blockchain explorer for Bitcoin, you’ll find that the process is quite similar for other cryptocurrencies. Let’s look at how to view transactions and wallet balances for some of the major altcoins.
Ethereum
To view Ethereum transactions and wallet balances, you can use Etherscan.io. This is Ethereum’s most popular block explorer. Simply enter an Ethereum wallet address or transaction hash into the search bar to pull up the details. You’ll be able to see the transaction amount, gas fee paid, and other info. Etherscan also allows you to view details on Ethereum-based tokens, smart contracts, and Dapps.
Litecoin
For Litecoin, check out Litecoin Explorer or LTC Block Explorer. These sites work similarly to Bitcoin block explorers, allowing you to look up Litecoin transaction IDs, view wallet balances, see network statistics, and more.

The user experience may differ slightly between sites and cryptocurrencies, but the core functionality remains largely the same. Blockchain explorers provide a window into the transparent and open nature of crypto networks.
Privacy Concerns With Public Blockchains
Lack of Anonymity
Public blockchains like Bitcoin and Ethereum are pseudonymous, meaning your real name is not directly tied to transactions, but your wallet address and transaction details are visible to anyone. While your name and personal information may not be displayed, analytics tools can be used to link your identity to transactions over time. For those who value privacy, public blockchains may be concerning.
Your Information is Permanent
Once a transaction is recorded on a public blockchain, it cannot be changed or removed. Your wallet balance, transaction history, and other details become a permanent part of the public record. For smaller purchases, this may not be an issue, but for larger financial transactions or sensitive data, immutability could be a downside. Some argue this lack of privacy deters mainstream adoption of public blockchains.
Data Can Be Tracked
On public blockchains, your wallet address, transaction data and other information can potentially be monitored and analyzed by third parties. Governments, corporations, and individuals may be able to track how you earn, spend, and transfer digital currencies or other crypto-assets. Your transaction history and wallet balance could potentially be linked to your real-world identity. For those concerned about surveillance or data privacy, public blockchains may be unappealing.
To address these concerns, some turn to private blockchains or mixers and tumblers that can help obfuscate transaction details. Others advocate for built-in privacy features on public blockchains that allow for optional anonymity. Balancing transparency and privacy remains an open challenge for public blockchain networks. With time, technology and standards may evolve to give users more control over their data and digital footprints.
Tips for Safe Blockchain Lookup
Now that you understand the basics of blockchain explorers, you’ll want to use them safely and responsibly. Here are some tips to keep in mind:
Double check that you’re using an official explorer for that blockchain. There are many scam sites out there phishing for your info. Only use well-known, verified explorers like Blockchain.com for Bitcoin or EtherScan for Ethereum.
Never enter your private keys or wallet passwords/recovery phrases into an explorer. They don’t need that info to function. If a site asks for those credentials, it’s likely a scam.
Be careful when sharing your public wallet addresses. Although they don’t reveal sensitive data, associating multiple addresses with your identity can make you a target. Use a new address for each transaction when possible.
Double check transaction details before sending funds. Make sure the recipient address, amount, and any smart contract details are correct. Once a transaction is broadcast to the network, it cannot be reversed.
Monitor your transactions to ensure proper confirmations. Most explorers will show an initial “unconfirmed” status until the network has verified the transaction. This usually takes a few minutes but can take longer when networks are busy. Don’t consider the funds “yours” until you see the confirmed status.
Be on alert for phishing emails or messages containing links to explorers. Never click links in unsolicited communications. Only visit explorer sites by typing their URL into your browser.
Explorers provide a useful window into the blockchain world. But like any tool, they can be misused or manipulated. By following these tips, you can enjoy the benefits of blockchain explorers while avoiding common scams and pitfalls. Staying vigilant about your security and privacy will serve you well in the world of crypto.
Blockchain Lookup Made Easy FAQs
To understand blockchain better, you probably have some questions about how it all works. Here are some of the most common FAQs about blockchain lookup to help clarify things.
How do I view my blockchain transactions?
Using a block explorer, you can view details of transactions on public blockchains like Bitcoin and Ethereum. Enter your wallet address or transaction ID to see information like the date, amount, and status of your transactions.
What is a transaction hash or ID?
A transaction hash, also known as a transaction ID, is a unique string of letters and numbers that identifies a single transaction on the blockchain. Each transaction that occurs is recorded on the public ledger and given its own ID.
Why are some of my transactions “unconfirmed”?
Transactions must be verified by miners before they are completed and added to the blockchain. During busy times, there may be a backlog of transactions waiting to be confirmed. Unconfirmed transactions are in the queue to be verified and added to the next block. They should confirm within a few hours, but may take longer.
How do I find my wallet balance?
To see your wallet balance, you need to enter your wallet address into a block explorer. Your wallet address acts as an account number, and the explorer will query the blockchain to calculate your total balance based on the transactions associated with that address. Some wallets also allow you to view your balance directly inside the wallet software or mobile app.
What information is displayed for each transaction?
Block explorers provide details for each transaction like:
•The date, time and block the transaction was recorded.
•The transaction hash (ID) to uniquely identify it.
•The wallet addresses of the sender and recipient.
•The amount of cryptocurrency transferred.
•The transaction fee paid (if any).
•The number of confirmations the transaction has received.
•Any smart contract details (for Ethereum transactions).
Does a block explorer show my personal information?
No, block explorers only show transaction details and wallet addresses which are pseudonymous. Your personal information is not recorded on the public blockchain. However, your transactions and balance may still be linked back to you if any identifiable information was used to obtain your cryptocurrency or linked to the transactions. For privacy, use a wallet that generates new addresses for each transaction.
