Fork of [pychainpoint](https://github.com/lontivero/PyChainpoint).\n\n### Installation\n\n```\n$ pip install chainpoint3\n```\n\n### Usage\n\nUse the is_valid_receipt function to validate your Chainpoint receipt.\n```python\nchainpoint_validate.is_valid_receipt(receipt)\n\n#  receipt - the receipt to be validated, as a string\n```\n\n#### Example\n\n```python\nfrom chainpoint3 import Chainpoint\n\nreceipt = '''{\n    \"header\": {\n        \"chainpoint_version\": \"1.1\",\n        \"hash_type\": \"SHA-256\",\n        \"merkle_root\": \"5faa75ca2c838ceac7fb1b62127cfba51f011813c6c491335c2b69d54dd7d79c\",\n        \"tx_id\": \"b84a92f28cc9dbdc4cd51834f6595cf97f018b925167c299097754780d7dea09\",\n        \"timestamp\": 1445033433\n    },\n    \"target\": {\n        \"target_hash\": \"cbda53ca51a184b366cbde3cb026987c53021de26fa5aabf814917c894769b65\",\n        \"target_proof\": [{\n            \"parent\": \"4f0398f4707c7ddb8d5a85508bdaa9e22fb541fa0182ae54f25513b6bd3f8cb9\",\n            \"left\": \"cbda53ca51a184b366cbde3cb026987c53021de26fa5aabf814917c894769b65\",\n            \"right\": \"a52d9c0a0b077237f58c7e5b8b38d2dd7756176ca379947a093105574a465685\"\n        }, {\n            \"parent\": \"5faa75ca2c838ceac7fb1b62127cfba51f011813c6c491335c2b69d54dd7d79c\",\n            \"left\": \"4f0398f4707c7ddb8d5a85508bdaa9e22fb541fa0182ae54f25513b6bd3f8cb9\",\n            \"right\": \"3bd99c8660a226a62a7df1efc2a296a398ad91e2aa56d68fefd08571a853096e\"\n        }]\n    }\n}'''\nvalidator = Chainpoint()\nresult = validator.is_valid_receipt(receipt)\n```\n\n##### Sample Valid Result\n```python\ndict(\n  is_valid=True,\n  type: 'BTCOpReturn',\n  source_id: 'f3be82fe1b5d8f18e009cb9a491781289d2e01678311fe2b2e4e84381aafadee',\n  exists: true\n)\n```\n\n\n##### Sample Invalid Result\n```python\ndict(\n  is_valid=False,\n  error='Cannot parse receipt JSON'\n)\n```\n\n\n",
