createzkSNARKProof

Creates a simplified zkSNARK proof demonstrating the correct execution of a general computation. This version is optimized for resource-constrained devices like the ESP32.

The proof attests that someone possesses secret data (privateData), executed a specific circuit (computation) with this data and publicInputs, and obtained the correct result, all without revealing the privateData.

Parameters

Parameter	Type	Description
privateData	const std::vector<uint8_t>&	The secret data known only to the prover (e.g., a private key).
publicInputs	const std::vector<uint8_t>&	Public inputs known to both prover and verifier (e.g., a hash).
circuit	const String&	A description identifying the computation being proven (simplified).
outProof	zkSNARKProof&	Output: The generated zkSNARK proof structure.

Return Value

• bool: Returns true if the proof was created successfully, false otherwise.

Example Code (main.cpp)

#include <Arduino.h>
#include <vector>
#include "Infratic-lib.h" // Assume zkSNARKProof struct is defined here

// This function does not require network connectivity.
Infratic solana(""); // RPC URL not needed

void setup() {
    Serial.begin(115200);
    delay(1000);

    Serial.println("\n=== createzkSNARKProof Example ===");

    // Hypothetical data for proving "knowledge of x such that x^2 = 9"
    std::vector<uint8_t> privateData = { 0x03 }; // Secret witness: x = 3
    std::vector<uint8_t> publicInputs = { 0x09 }; // Public input: result = 9
    String circuit = "simple_square_circuit"; // Identifier for the circuit used

    zkSNARKProof proof; // This struct is defined in Infratic-lib.h

    Serial.println("Creating simplified zkSNARK proof...");

    if (solana.createzkSNARKProof(privateData, publicInputs, circuit, proof)) {
        Serial.println("✅ zkSNARK proof created successfully!");
    } else {
        Serial.println("❌ Failed to create zkSNARK proof.");
    }
}

void loop() {
    // Can be left empty
