Title: New Bitcoin Block Format Post by: jacko27 on December 02, 2017, 10:33:12 AM What’s the best resource to see the actual bitcoin block in it’s raw readable format?
For example, if I want to see the actual bitcoin block data?

For example, if I want to see the actual bitcoin block data? Download the block chain with Bitcoin Core and use a hex editor to look in the files. Or is that too low a level?

For example, if I want to see the actual bitcoin block data? The best resource to see the actual bitcoin block in its raw readable format is the hex Editor. After you have gotten the block hex (the raw data for the block itself), you can then make it a file by putting the hex into a hex editor or better still you can save the hex as a string in a text file.

Or is that too low a level? Or you could use the getblock command to get the block as a hex string or decoded in JSON.Title: Re: New Bitcoin Block Format Post by: haltingprobability on December 02, 2017, 07:51:37 PM What’s the best resource to see the actual bitcoin block in it’s raw readable format?

As long as you're not doing anything that requires trust (in which case, you should use Core), you can just go to: Code: https://blockexplorer.com/api/rawblock/<block_hash> Title: Re: New Bitcoin Block Format Post by: jacko27 on December 03, 2017, 04:43:51 PM What’s the best resource to see the actual bitcoin block in it’s raw readable format?
