Basic Features of a Blockchain Explorer
A blockchain explorer provides various insights into network activity, including:
1. Transaction Details
- Every transaction on the blockchain has a unique transaction hash (TX Hash).
- Clicking on a TX Hash in an explorer reveals:
- Sender & Receiver Addresses: Who sent and received the transaction.
- Transaction Status: Whether the transaction succeeded, failed, or is pending.
- Block Number: The block in which the transaction was confirmed.
- Gas Fees: The cost paid for the transaction (in ETH, SOL, etc.).
- Smart Contract Interactions: Whether the transaction involved a DeFi protocol, NFT mint, or token swap.
2. Token & Token Holder Data
For any token contract, you can check information such as:
- The Top Holders: The largest wallets holding a specific token
- Supply Distribution: How concentrated the token supply is
- Transfers: Recent transfers of the token across wallets.
3. Network Blocks & Validators
Blockchains process transactions in blocks, which validators or miners create.
Explorers show:
- Latest Blocks: Recently added blocks to the chain.
- Validator Information: The entity responsible for validating the block (PoS networks like Ethereum and Solana display this).
- Epochs & Finality: On Solana, for example, you can track validator rewards and epoch progress.
4. Contract & Smart Contract Execution
On EVM-compatible chains (Ethereum, Avalanche, BNB Chain), smart contracts can be explored to:
- Read contract functions.
- View interactions with DeFi, NFTs, and DApps.
- Check the source code (if verified) for transparency.
