　　Blockchain Search Q&A Guide

　　Q1: What is a Block Height and how do I search it?

　　A:

　　A block height is the number that identifies a block’s position in the blockchain.

　　Example: Bitcoin Block 840,000

　　To search → enter the number like 840000.

　　The explorer will show details such as block hash, timestamp, miner, and transaction count.

　　Example:

　　Block Height: 840000 → shows block info (e.g., mined 2024-07-13, 2,345 transactions, size 1.2 MB).

　　Q2: What is a Block Hash and how do I search it?

　　A:

　　Every block has a unique 64-character hexadecimal hash (like a digital fingerprint).

　　Example:

　　0000000000000000001a93b47e6a44e57e37b7a6f3548c7f2d3cd71fa2f4cbb4

　　Paste this hash into the search box → you’ll see all block details: confirmations, height, timestamp, and reward.

　　Tip: Hashes always look long and random, made of numbers and lowercase letters a–f.

　　Q3: What is a Transaction Hash (TxID)?

　　A:

　　A transaction hash (TxID) is the unique identifier of a single blockchain transaction.

　　Example (Bitcoin TxID):

　　b6f6991d05f71d8a53b1d3a4c0ec34c61d93d8e2b82b4d134f70f5e6f7c6c8f1

　　Enter this TxID to see sender, receiver, amount, fees, and confirmations.

　　Note: Each blockchain has its own transaction hash format, but they all serve the same purpose: identify a transaction.

　　Q4: What is an Address and how do I search it?

　　A:

　　A wallet address identifies a user or account on the blockchain.

　　Example:

　　Bitcoin: bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh

　　Ethereum: 0x742d35Cc6634C0532925a3b844Bc454e4438f44e

　　When you enter an address, you’ll see the wallet balance, number of transactions, and activity history.

　　Pro Tip:

　　Addresses differ by network:

　　BTC: Starts with 1, 3, or bc1

　　ETH / BNB / USDT (ERC20): Starts with 0x

　　DOGE: Starts with D

　　SOL: 44-character Base58 string

　　Q5: What happens if I search the wrong format?

　　A:

　　The explorer automatically detects if the input is a block number, hash, or address —

　　If it doesn’t match any pattern, it will show a “not found” message or suggest checking your input.

　　Q6: Can I search across multiple blockchains?

　　A:

　　Yes. If your explorer supports multiple networks, select your preferred blockchain (e.g., Bitcoin, Ethereum, Solana) before searching.

　　The system will query the correct API (Blockchair, Etherscan, SolanaFM, etc.) and return the results instantly.

　　Q7: What’s the difference between block, transaction, and address searches?

　　Search Type Input Example Shows

　　Block Height / Hash 840000 / 00000abc... Block details (miner, time, transactions)

　　Transaction Hash (TxID) b6f6991d05f7... Sender, receiver, amount, fee

　　Address 0x742d35Cc... Balance, total in/out, transaction list
