This module provides the SnarkjsService class, which interfaces with a snarkjs-based service to generate Zero-Knowledge Proofs (ZKPs).
+
The SnarkjsService class allows for sending a secret to a specified server endpoint and receiving a ZKP in return. It handles HTTP requests, response parsing, and error logging.
+
+
Dependencies:
+
requests: For making HTTP requests to the snarkjs service.
+
json: For parsing the JSON response from the service.
+
logging: For logging error messages.
+
+
+
Example:
service = SnarkjsService()
+proof = service.generate_proof(secret=’my_secret’)
SnarkjsService provides an interface to a snarkjs-based server for generating Zero-Knowledge Proofs (ZKPs).
+
It sends a secret to the server and retrieves a ZKP. The class handles the details of making the HTTP request,
+processing the response, and error handling. It is designed to work with a server running snarkjs that exposes
+a /compute_commitment endpoint.
+
+
Attributes:
base_url (str): The base URL of the snarkjs server. Defaults to ‘http://localhost:8888’.
+endpoint (str): The endpoint for computing the commitment. Defaults to ‘/compute_commitment’.
+
+
Methods:
+
generate_proof(secret): Takes a secret, sends it to the snarkjs server, and returns the generated ZKP.
Returns None if the server response is not successful or if an error occurs.
+
+
+
+
Example:
service = SnarkjsService()
+proof = service.generate_proof(secret=’my_secret’)
