Notes

This page updates every 5 seconds.
Use the search bar at the top of the website to search for transactions and blocks.
Memory pool size (vMB) is the total size of the raw transaction data (not including metadata).
Block size (MB) does not include block header, tx count, or coinbase transaction.
Feerates are in sats/vbyte.

AFR = Average Feerate

About

This is a basic blockchain explorer for exploring Bitcoin data.

The main features of this explorer are:

Basic. The data is laid out to try and represent the structure of raw transactions and blocks.
Fast. I've made the pages load as fast as I can. If you can't be pretty, you might as well be fast.

So it's pretty basic, but I think you can learn a lot about how Bitcoin works by browsing the raw data and seeing how it all connects together.

Data

The data on this explorer comes from the following sources:

Bitcoin Core. This is used to get raw transaction and block data. This is retrieved via simple bitcoin-cli commands.
SSDB. I'm using a custom database to store the address balances and spent locations of each output. Bitcoin Core does not store this information, so I'm using a custom script and database to store this extra information.

Privacy

This blockchain explorer does not track anything.

I do not collect IP addresses or keep track of requests. Nor do I use any third-party analytics or tracking software.

However, this blockchain explorer is not open-source, so you have to trust me on this one.

Bitcoin Core Explorer

If you want to explore blockchain data without having to trust anyone with your privacy, the simplest way to do this is to run your own Bitcoin Core node and run bitcoin-cli commands.

The two most useful commands are:

bitcoin-cli getrawtransaction <txid>
bitcoin-cli getblock <hash>

You will need to add txindex=1 to your bitcoin.conf configuration file to be able to query for all transactions.
Use bitcoin-cli help to a complete list of commands.
Use bitcoin-cli help <command name> to see detailed information about a command and all the available options.

Alternatively, you can also run your own self-hosted explorer such as mempool or btc-rpc-explorer.
