What is a blockchain explorer and what does it show?
A blockchain explorer is a public search tool for blockchain records. It shows a transaction's confirmations and fee, but it cannot move or recover funds.

- Explorers read public data and hold no coins.
- Result pages show confirmations, height, timestamp and fee.
- Nodes and indexes turn blocks into search results.
- Fake explorer sites may phish for a seed phrase.
A blockchain records transactions in blocks, and each block links to the one before it, so anyone can audit the record. An explorer is how most people read that record.
What a blockchain explorer does
An explorer shows the public side of a blockchain. You use one to check whether a payment arrived and which block holds it, or to study how a network is used.
How to look up a transaction
Paste a transaction hash into the search box to find one transfer, or paste a public address to see its full history. The result page reports a standard set of fields.
How blockchain explorers work
An explorer does not create data. It connects to nodes that follow the network's rules and share its blocks, then builds an index so searches return quickly. A full node keeps the whole blockchain; a light node does not.
Explorer versus wallet or exchange
These tools do different jobs. A wallet holds private keys and signs the transactions you send. A centralized exchange holds customer balances and can move crypto for them. An explorer only reads public records.
- A wallet signs and sends your transactions.
- A centralized exchange holds customer balances.
- An explorer holds no coins and cannot sign anything.
What explorers cannot do
An explorer cannot recover funds, reverse a transaction, or refund a payment. A recent transaction can still be undone by a chain reorganization, but once one sits deep enough in the chain, reversing it becomes impractical. An explorer also cannot keep an address private.
Frequently asked questions
Basic searches on public explorers are free. Some operators charge for bulk data or faster access.
Yes. Explorers read public data, so you can search without owning a wallet.
Most public blockchains have at least one, often run by a foundation or an independent team. Private or permissioned chains may not offer a public one.
A public address is not a wallet, and sharing it does not give anyone access to your funds. Use a known explorer, since copycat sites may collect personal details.
