Perhaps you’ve heard the term “block explorer” or “Blockchain browser” before but didn’t understand what it means.
A block explorer allows you to search and navigate through the block chain. Using a block explorer you can check the balance of different Bitcoin public addresses, track coin transfer histories watch how many confirmations a transaction has and get a wide variety of statistics about the network such as the current hash rate and more.
For each block chain there is a different block explorer – so for example you won’t be able to use a Bitcoin block explorer in order to examine Litecoin’s blockchain unless you use a multi-blockchain block explorer like Blockchair.
What can you do with a block explorer ?
Usually the block explorer software will supply some or more of the following:
- a list of a chain’s recent blocks
- transactions in a given block
- links to the previous and next transaction involving each input and output
- a list of all transactions involving a given address
- current and historical address balances
- a way to search for blocks, transactions, and addresses
Here’s an example of how to examine a public Bitcoin address using the most popular block explorer today blockchair.
I just paste the public address into the block explorer and now I can see how many Bitcoins this wallet holds and its recent transactions.
If I click on a specific transaction a can see details about this transaction such as when it was received, the number of confirmations it has or when it is estimated to be confirmed, the inputs and outputs of this transaction and how many Bitcoins were transferred.
A list of 8 different Bitcoin block explorers
- Blockchair – The most versatile and robust blockchain explorer on the market. This platform allows users to search across 43 different blockchains and has multiple additional features such as portfolio trackers, ENS lookup, transaction receipts, wallet statements, node explorers, datasets, news aggregation and more. You can learn everything you need to know about it in our detailed Blockchair Review.
- Blockchain.info – One of the most popular Bitcoin block explorers today. The company also provides a very popular (and recommended) Bitcoin wallet.
- Blockr.io – A multi-currency block explorer. Used not only for Bitcoin but also for Litecoin, Peercoin and more. On August 2014 Coinbase purchased Blockr.io (mainly for the talent of the developers).
- Blockexplorer.com – Perhaps not as well designed as the others but definitely the longest existing block explorer. The website supplies the basic information for all Bitcoin transactions and wallets.
- Insight.is – The Insight REST API provides a convenient, powerful and simple way to read data from the bitcoin network and build your own services with it.
- mempool.space – A real-time Bitcoin mempool and blockchain explorer that shows fee markets, RBF status, and transaction details in a clear, easy-to-use way.
- Blockstream Explorer – A privacy-focused explorer for Bitcoin and the Liquid Network with a clean interface.
- OKLink – A multi-chain explorer with dedicated sections for Ordinals and Runes.
And if you’re still looking for different block explorers you can try one of these as well: Blocktrail, Biteasy, BTClook, BitcoinChain.
Block explorers, also known as blockchain browsers, are tools that let anyone search and explore what’s happening on a blockchain. They work like search engines, giving you a clear view of transactions, blocks, addresses, and even network activity in real time. Over the past few years, block explorers have evolved a lot, both in what they cover and the features they offer.
One of the biggest developments came in March 2024, when Ethereum’s Dencun upgrade introduced a new type of transaction called “blobs.” These help Layer 2 networks scale by cutting data costs. Major explorers like Etherscan and Blockscout now include blob pages so anyone can view and track these transactions directly.
Bitcoin explorers have also expanded their coverage. When the Runes protocol launched during the April 2024 halving, many explorers added dedicated sections for Runes and Ordinals. OKLink and mempool.space were among the first to support these features. In 2025, mempool.space released version 3, which included a built-in Accelerator and a smoother browsing experience.
Etherscan, long considered the go-to for Ethereum, has grown far beyond its original scope. It now supports multiple chains, offers Explorer-as-a-Service for other networks, and has introduced built-in anti-scam features to highlight suspicious transactions like zero-value transfer spam. In late 2023, Etherscan also acquired Solscan, the most popular third-party Solana explorer, which strengthened its multi-chain presence.
Other networks have gone through major changes too. Avalanche’s Snowtrace explorer shut down its original Etherscan-powered version in 2023 and relaunched in 2024 with the Avascan team. This shows how even official explorers can evolve and switch providers as ecosystems grow.
Beyond Bitcoin: Ethereum, EVM, and Solana Explorers
Block explorers are no longer limited to Bitcoin. Most major networks now have their own dedicated explorers, and many support multiple chains:
- Ethereum and EVM networks: Etherscan remains the leading option, with sister sites like BscScan, Polygonscan, Arbiscan, and BaseScan covering other chains in the ecosystem. Blockscout is another popular open-source choice. Both have added support for blob transactions introduced by the Dencun upgrade.
- Solana: Solscan is the most widely used third-party explorer, and its acquisition by Etherscan in 2024 helped modernize it further. The official Solana Explorer is also available for basic browsing.
Modern Features and Scam Protection
Modern explorers offer far more than just transaction lookups. Many now include NFT sections, token pages, pending transaction pools, and advanced filtering options. They also help protect users by flagging risky activity. For example, Etherscan now warns users about zero-value transfer scams, which try to trick people into thinking they’ve received tokens when they haven’t. These features make today’s explorers not only more powerful but also safer to use.
