Blockchain technology powers the digital revolution behind cryptocurrencies, offering transparency, security, and decentralization. To truly understand what’s happening beneath the surface of crypto transactions, a blockchain explorer is an essential tool. Think of it as a search engine for blockchain data—like Google for Bitcoin, Ethereum, and Litecoin. This guide will walk you through everything you need to know about using a block explorer, how to interpret key metrics, and why it matters to traders, miners, and crypto enthusiasts.
Whether you're verifying a transaction, analyzing network activity, or simply exploring how blockchains work, this comprehensive walkthrough will equip you with practical knowledge and confidence.
What Is a Blockchain Explorer?
A blockchain explorer is an online tool that allows users to view real-time and historical data on blockchain networks. It enables you to search for:
- Specific blocks (collections of transactions)
- Individual transactions using a transaction hash (TxID)
- Public wallet addresses
- Ethereum Name Service (ENS) domains
Every cryptocurrency transaction is recorded on a decentralized digital ledger called the blockchain. These records are grouped into blocks, which are verified by network participants—such as miners in Proof-of-Work systems—and permanently chained together. Once confirmed, data cannot be altered, making the blockchain tamper-proof.

The CoinMarketCap block explorer supports major networks including Bitcoin, Ethereum, and Litecoin, providing a user-friendly interface to monitor network health, transaction status, and market-linked blockchain metrics.
Who Uses a Blockchain Explorer?
- Traders & Users: Check if their crypto payments have been sent or received.
- Miners: Verify block creation and reward distribution.
- Analysts & Enthusiasts: Track supply metrics, hash rates, and network congestion.
It’s a no-frills gateway into the inner workings of blockchain ecosystems—offering transparency without complexity.
Navigating the Homepage
When you open the block explorer, the homepage presents a clean layout designed for quick access. On the left, the CoinMarketCap logo takes you back to the main dashboard at any time. The top-right corner includes:
- A language selector (English or Simplified Chinese, with more coming)
- A search bar pre-set to Bitcoin but switchable to Ethereum or Litecoin
This persistent search bar is your primary entry point. You can look up:
- Block height (e.g., 840000)
- Transaction ID (TxID)
- Wallet address
- ENS name (on Ethereum)
Always use copy-paste when entering sensitive data like addresses or hashes to avoid errors.
How to Use the Main Search Bar
The main search functionality supports four types of queries:
- Blocks – Enter a block number to see all transactions within it
- Transactions – Paste a TxID to verify payment status
- Wallets – Input an address to view balance and transaction history
- ENS Names – Search human-readable Ethereum addresses (e.g., vitalik.eth)
By default, searches are performed on the Bitcoin network. Click the dropdown arrow next to the search field to switch between Bitcoin, Ethereum, and Litecoin.
For example, if you’re waiting for a Bitcoin transfer, simply paste your wallet address into the search bar. The explorer will display:
- Current balance
- Incoming and outgoing transactions
- Confirmation status
While you could scroll through recent blocks manually, it’s far more efficient to use direct search—especially since blocks can contain thousands of transactions.
Understanding Blockchain Overviews
Scrolling down the homepage reveals real-time overviews for Bitcoin, Ethereum, and Litecoin. Each section displays:
- Current price in USD
- Market cap
- Circulating supply
- Max supply
- Hash rate
These figures are powered by CoinMarketCap’s live data feeds and update continuously based on market activity.
Key Market Data Explained
Market Cap
Calculated as:
Price × Circulating Supply
For example:
$7,353.24 × 17,698,112 BTC = **$130.1 billion**
We use circulating supply—coins actively traded—not max supply, because locked or reserved tokens don’t influence market pricing.
Max Supply
The maximum number of coins that will ever exist. Bitcoin’s is capped at 21 million.
Hash Rate
Measures network computing power. Bitcoin’s current rate might be listed as 47.98 EH/s (exahashes per second), meaning nearly 48 quintillion calculations per second secure the network.
Higher hash rates indicate stronger network security and miner participation.
Recent Blocks: Real-Time Activity
To the right of market data, color-coded bars represent the most recent blocks on Bitcoin (yellow) and Ethereum (blue). Blocks are arranged chronologically—left to right—with the latest on the far right.
Block height increases with each new block. Hover over any bar to see:
- Block number
- Number of transactions included
Taller bars mean more transactions were processed during that period—indicating higher network usage.
Each block contains:
- A unique hash ID
- Timestamp
- List of confirmed transactions
- Reference to the previous block’s hash (ensuring chain integrity)
Once added, blocks are immutable. This permanence is what makes blockchain resistant to fraud and tampering.
How to View Specific Blocks
To dive deeper into block details:
- Hover over the three dots near “Recent Blocks”
- Click “View Block”
You’ll be taken to a list of recent Bitcoin blocks. Click any block height to open its contents.
Alternatively, use the top-right search bar to directly enter a block number.
On the block details page, you’ll see:
- Block Height: Sequential number of the block
- Hash ID: Unique cryptographic fingerprint
- Transactions: Total number confirmed in that block
- Timestamp: When it was mined (in YYYY-MM-DD format)
Clicking a specific block opens all contained transactions—revealing senders, recipients, amounts, and fees.
Inside Bitcoin Blocks: Mining and Difficulty
The Bitcoin blocks page includes additional metrics:
- Pending Txs: Transactions waiting for confirmation due to network congestion or low fees
- Difficulty: How hard it is to mine a new block; adjusts every 2016 blocks (~every two weeks)
- BTC Dominance: Bitcoin’s market cap as a percentage of the total crypto market
Miners compete to solve complex puzzles using computational power. The first to succeed adds the block and earns:
- The block reward (newly minted BTC)
- All associated transaction fees
This process ensures decentralized consensus and network security.
Exploring Transactions
Click the “Transactions” tab to view individual payments within a block.
Each transaction has a unique:
- TxID (Transaction ID): A cryptographic hash serving as proof of payment
- Fee: Paid to miners; depends on transaction size, not value
- Confirmation Status: Green means confirmed
Interestingly, sending $6 million in BTC may cost only $3 in fees—far cheaper than traditional banking. Fees are based on data size (in bytes), not monetary value.

Transaction Confirmations
A transaction gains security with each new block added after it:
- 1 confirmation = included in one block
- 6 confirmations ≈ 1 hour (recommended for high-value BTC transfers)
More confirmations = higher resistance to double-spending attacks.
What Are UTXOs in Bitcoin?
Bitcoin doesn’t store balances like bank accounts. Instead, it uses Unspent Transaction Outputs (UTXOs)—small fragments of BTC from past transactions.
When you send BTC:
- The wallet selects enough UTXOs to cover the amount + fee
- Sends change back to your address
- Marks used UTXOs as “spent”
This model enhances privacy and scalability across the network.
Wallet Address Insights
Clicking any address opens its dedicated page showing:
- Current balance
- Total received and sent
- QR code for easy sharing
- Full transaction history (incoming/outgoing)
It functions like a public bank statement—transparent but pseudonymous.
Ethereum: Gas, Gwei, and Nonce
Ethereum goes beyond payments with smart contracts—self-executing agreements coded on-chain.
Key concepts:
- Gas: Unit measuring computational effort
- Gwei: Denomination (1 Gwei = 0.000000001 ETH)
- Gas Price: How much you’re willing to pay per unit of gas
- Gas Limit: Maximum gas you’ll allow (e.g., 21,000 for simple sends)
- Nonce: Sequential counter preventing duplicate transactions
Unused gas is refunded. Complex dApp interactions require more gas than simple transfers.
Litecoin: Address Format Changes
After forking from Bitcoin, Litecoin modified its Pay-to-Script-Hash (P2SH) addresses from starting with “3” to “M” to reduce confusion between networks. Both formats represent the same underlying technology—just different encodings.
