Foundations of Blockchain

MultiChain JSON-RPC driver

We'll be using a driver to communicate with the MultiChain node. MultiChain provides a JSON-RPC server that can be used to perform any blockchain operations that is needed.

In our use case, we'll be using a Python driver called Savoir, which will connect to the JSON-RPC server of the MultiChain node and invoke the requisite functions:

from Savoir import Savoir 
 
class MultichainClient(object): 
 
    def __init__(self, **kwargs): 
 
        self.rpcuser = kwargs.get('rpcuser', 'multichainrpc') 
        self.rpcpasswd = kwargs.get('rpcpasswd', 'HFzmag67bJg2f4YuExgVDqQK5VfnvXRS5SKrByuCgiXm') 
        self.rpchost = kwargs.get('rpchost', 'localhost') 
        self.rpcport = kwargs.get('rpcport', '4416') 
        self.chainname = kwargs.get('chainname', 'chain1') 

We will ...
