Description: # pychainpoint
        
        
        
        A Python 3 module for validating Chainpoint blockchain receipts. Fork of [pychainpoint](https://github.com/lontivero/PyChainpoint).
        
        ### Installation
        
        ```
        $ pip install chainpoint3
        ```
        
        ### Usage
        
        Use the is_valid_receipt function to validate your Chainpoint receipt.
        ```python
        chainpoint_validate.is_valid_receipt(receipt)
        
        #  receipt - the receipt to be validated, as a string
        ```
        
        #### Example
        
        ```python
        from chainpoint3 import Chainpoint
        
        receipt = '''{

        ##### Sample Invalid Result
        ```python

          error='Cannot parse receipt JSON'
