What is your goal on checking the contents of the blocks?
There are couple of sites with already parsed data:
If it was the ASCII texts embedded in the blockchain, all of them were already parsed here:
https://bitcoinstrings.com/If it was the block headers and/or transaction data (
in hex or readable format), you can check them out here:
https://webbtc.com/ <- however, the site isn't updated to the latest height (
till 443888 only) but can be converted to HEX: ex.
https://webbtc.com/block/0000000000000000000cdc0d2a9b33c2d4b34b4d4fa8920f074338d0dc1164dc.hexI downloaded several from internet but they were not work out.
Most of those parser won't work with blocks from
477,120 (
inaccurate, somewhere around blk00950.dat) to the latest.
Those are the blocks containing SegWit data.
