getblock JSON-RPC command

getblock "blockhash" ( verbosity )

If verbosity is 0 or false, returns a string that is serialized, hex-encoded data for block 'hash'.
If verbosity is 1 or true, returns an Object with information about block <hash>.
If verbosity is 2, returns an Object with information about block <hash> and information about each transaction.

Arguments

1. "blockhash"           (string, required) The block hash
2. verbosity             (numeric, optional, default=1) 0 for hex-encoded data, 1 for a json object, and 2 for json object with transaction data

Result (for verbosity = 0)

"data"                   (string) A string that is serialized, hex-encoded data for block 'hash'.

Result (for verbosity = 1)
