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.
All of the fee rates are in sats/vbyte.

AFR = Average Fee Rate

About

This is a basic blockchain explorer for exploring Bitcoin data.

All of the data comes directly from a Bitcoin Core node running on the same server as this website. This data is retrieved via bitcoin-cli commands.

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.

Limitations

This is not a fully-fledged explorer as it does not use a custom database.

This means there are a few limitations:

No address search. Bitcoin Core does not keep track of addresses and balances.
Cannot move forward through transactions. A single transaction doesn't include information about whether the outputs have been spent (or which transactions spent them), so whilst you can move backwards through the inputs, you cannot move forwards through the outputs.

So if you're looking for a more advanced explorer that offers these features, try mempool.space instead. But if you hate beautiful websites and only want to dig around raw data quickly, this explorer should do the job.

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 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.
