I've looked at some of the more popular blockchain explorers, but none of them seem to provide the feature I'm looking for. I'd like to find a blockchain explorer that allows you to see raw Tx data and raw block headers. The explorer's I've seen parse the raw data and present it in a more human readable format. Are there any that provide the raw data?

Thank you!


You can get this info from blockchain.info, by simply adding ?format=hexto the end of the relevant URL.

For example, here is a recent block (height 509,244):


And here is the raw data for that block, in hex:


(Note that you will need to parse the block header out of this data, as that URL will dump the raw data for the entire block)

Similarly, here is a transaction from that block:


And here is the raw data from that transaction, in hex
