Blockchain technology has revolutionized the way we think about data transparency, security, and decentralization. One of the most powerful tools in a crypto user’s toolkit is the block explorer—a digital window into the inner workings of a blockchain network. Think of it as a search engine for blockchain data, allowing you to track transactions, verify wallet balances, and explore network activity in real time.
In this comprehensive guide, we’ll walk you through how to use Core Scan, the official block explorer for the Core blockchain, an EVM-compatible layer-one chain powered by Bitcoin’s security. Whether you're new to blockchain or looking to deepen your understanding of transaction tracking and on-chain analysis, this tutorial will equip you with essential knowledge and practical skills.
What Is a Block Explorer?
A block explorer is a web-based tool that enables users to view and interact with the data stored on a blockchain. Just like Google lets you search the internet, a block explorer lets you search for:
- Specific transactions
- Wallet addresses
- Block details
- Token transfers
- Smart contract interactions
Block explorers are fundamental for transparency, security verification, and troubleshooting in decentralized networks.

Introducing Core Scan
Core Scan (https://scan.coredao.org/) is the native block explorer for the Core blockchain, designed specifically for ease of use and deep data access. As an EVM-compatible chain secured by Bitcoin—leveraging 50% of Bitcoin’s hash power—Core offers robust infrastructure for decentralized applications (dApps), DeFi protocols, and Bitcoin-integrated financial innovations (BTCfi).
With over 18 million unique addresses and more than 263 million transactions since its January 2023 mainnet launch, Core has become one of the fastest-growing EVM chains aligned with Bitcoin’s security model.
Key Features of Core Scan:
- Search transactions by hash
- View wallet address history and balance
- Explore mined blocks and validators
- Track token transfers (including CORE and ERC-20s)
- Interact with smart contracts
- Monitor network statistics in real time
How to Use Core Scan: A Step-by-Step Guide
1. Navigate to Core Scan
Open your browser and go to: https://scan.coredao.org/
You’ll land on the homepage, which displays key network metrics:
- Latest blocks
- Recent transactions
- Top accounts
- Network hash rate and gas prices
This dashboard gives you a pulse of the network at a glance.
2. Search for a Transaction
Every transaction on the Core blockchain has a unique transaction hash (Txn Hash)—a long alphanumeric string.
To look up a transaction:
- Copy the Txn Hash from your wallet or dApp.
- Paste it into the search bar at the top of Core Scan.
- Press Enter.
The results page will show:
- Status (Success/Fail)
- Timestamp
- From and To addresses
- Value transferred (in CORE or tokens)
- Gas used and fees
- Confirmations count
This is invaluable when confirming if a transaction went through or is stuck.
3. Check Wallet Address Activity
Want to view someone’s wallet activity? Or verify your own balance?
Enter any wallet address into the search bar. You’ll see:
- Current balance (CORE and tokens)
- Total incoming and outgoing transactions
- Token holdings (via ERC-20 support)
- Internal transfers and contract interactions
Note: While all data is public, wallet identities remain pseudonymous unless linked externally.
4. Explore Blocks and Validators
Core operates under a Proof-of-Stake consensus mechanism enhanced by Bitcoin’s hashing power. Each block contains multiple transactions.
Click “Blocks” in the navigation menu to:
- See recently mined blocks
- View block reward distribution
- Identify validator addresses
- Drill down into individual transactions within a block
Understanding block propagation helps developers and analysts assess network health.

Why Use a Block Explorer?
Block explorers serve several critical functions across different user types:
For Everyday Users:
- Confirm receipt of funds
- Troubleshoot failed transactions
- Verify gas fees before sending
For Developers:
- Debug smart contract executions
- Monitor event logs
- Validate deployment addresses
For Researchers & Analysts:
- Track whale movements
- Analyze token distribution patterns
- Study network congestion trends
Using Core Scan regularly builds confidence in your interactions with the blockchain ecosystem.
Core Blockchain: The Bitcoin-Secured EVM Chain
What sets Core apart from other EVM-compatible chains is its deep integration with Bitcoin. By utilizing merged mining with Bitcoin, Core inherits immense computational security while enabling smart contracts.
Key facts:
- Over 4,800 BTC natively staked to secure the network
- Backed by 50% of Bitcoin’s hash power
- Hosts millions of DeFi users exploring BTCfi (Bitcoin Finance) use cases
- Supports seamless cross-chain asset bridging
This synergy makes Core one of the most secure and innovative platforms in the crypto space today.
Frequently Asked Questions (FAQ)
Q: Is Core Scan free to use?
Yes, Core Scan is completely free. There are no charges for searching transactions, addresses, or blocks.
Q: Can I track ERC-20 tokens on Core Scan?
Absolutely. Since Core is EVM-compatible, all ERC-20 tokens deployed on the network can be tracked using their contract addresses and transaction hashes.
Q: How fast are transactions confirmed on Core?
Transaction finality on Core typically takes just a few seconds, thanks to its optimized consensus mechanism and high throughput.
Q: Do I need an account to use Core Scan?
No registration is required. Core Scan is fully public and accessible to anyone with an internet connection.
Q: How does Core leverage Bitcoin’s hash power?
Through merged mining, miners simultaneously secure both Bitcoin and Core blockchains using the same computational work, enhancing security without additional energy costs.
Q: Can I interact with smart contracts via Core Scan?
Yes. You can read contract functions, view event logs, and even write to contracts directly through the interface if connected via MetaMask or another Web3 wallet.
Final Thoughts: Empower Yourself with On-Chain Data
Understanding how to navigate a block explorer like Core Scan puts you in control of your blockchain experience. No longer do you have to rely solely on third-party apps or wallets—you can independently verify every transaction, balance, and interaction on the network.
As blockchain adoption grows, so does the importance of transparency and self-sovereignty. Tools like block explorers are not just technical utilities—they’re gateways to trustless verification in a decentralized world.
Whether you're tracking a simple transfer or auditing a complex DeFi protocol, mastering Core Scan enhances your fluency in the language of blockchain.
