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)

8be750000b0100080100000000000000000000000000000000000000000000000000000000000000000000003ba3edfd7a7b12b27ac72c3e67768f617fc81bc3888a51323a9fb8aa4b1e5e4a29ab5f49ffff001d1dac2b7c

Additional resource I tried - Link

Note: I am using c# to read and parse the data.

  • This logic for parsing is up to date already. If you need to know how to parse RAW data, you can try my parser github.com/ragestack/blockchain-parser

  • @DenisLeonov, your code talks about parsing the bat files however my question is on Block index
