I am trying to read the value against block hash in level DB of Bitcoin node database - Block/index. For Genesis block, I get 88 bytes which I want to parse. I tried to follow instructions in https://bitcoin.stackexchange.com/questions/67515/format-of-a-block-keys-contents-in-bitcoinds-leveldb but wasnt able to do that successfully as the first 4 bytes should be version but I get an invalid version.
I tried obfuscating the whole value as well but still the first 4 bytes does not give me a valid version. I must be doing something wrong but not able to identify that.
Value I get (in hex string)
Additional resource I tried - Link
Note: I am using c# to read and parse the data.
