∟"getblock blockhash 0" - Serialized Hex Blcok Data

This section describes how to get Serialized Hex Blcok Data.

If you want to study the data structure used in a Bitcoin block, you should get a copy of the serialized and hex-encoded data from a given Bitcoin block.

For example, here is how I got the serialized and hex-encoded data from test Bitcoin clock # 500: 

C:\>\local\bitcoin-0.15.1\bin\bitcoin-cli -testnet getblockhash 500
00000000a2424460c992803ed44cfe0c0333e91af04fde9a6a97b468bf1b5f70

C:\>\local\bitcoin-0.15.1\bin\bitcoin-cli -testnet getblock
   00000000a2424460c992803ed44cfe0c0333e91af04fde9a6a97b468bf1b5f70 0
