query_global_state

This method allows for you to query for a value stored under certain keys in global state. You may query using either a Block hash or state root hash.

• Note: Querying a purse's balance requires the use of state_get_balance rather than any iteration of query_global_state.

Reference: Here

Parameters:

1. state_identifier - object identifier used for the query

2. key - string casper_types::Key as a formatted string

3. path - array path components starting from key as base
