LuminAIR Web is a WebAssembly-based verifier that allows you to verify LuminAIR proofs directly in the browser. This package provides a high-performance, secure way to verify proofs without needing a backend server.

​
Installation

npm install @gizatech/luminair-web
# or
yarn add @gizatech/luminair-web
# or
pnpm add @gizatech/luminair-web

​
Usage

Before using any verification functions, you need to initialize the WASM module: 
import init from '@gizatech/luminair-web';

// Initialize the WASM module
await init();

​
Basic Verification

The simplest way to verify a proof is using the verify function: 
import { verify } from '@gizatech/luminair-web';

const result = verify(proofBytes, settingsBytes);
if (result.success) {
  console.log('Proof verified successfully!');
} else {
  console.error('Verification failed:', result.error_message);
}

​
Advanced Usage

The package provides additional utilities and configuration options for more advanced use cases: 
import { verify, VerificationOptions, LuminairUtils } from '@gizatech/luminair-web';

// Configure verification options
const options: VerificationOptions = {
  timeoutMs: 30000, // 30 seconds timeout
  config: {
    enableDebugLogging: true,
    maxMemoryMB: 1024 // 1GB memory limit
  }
};

// Validate proof binary before verification
if (LuminairUtils.isValidProofBinary(proofBytes)) {
  const result = verify(proofBytes, settingsBytes);
  console.log(`Proof size: ${LuminairUtils.getProofSize(proofBytes)} bytes`);
}

API Reference

​
Main Functions

​
init()

Initializes the WASM module. Must be called before using any verification functions. 
function init(module?: WebAssembly.Module | Promise<WebAssembly.Module>): Promise<void>

​
verify()

Verifies a LuminAIR proof from binary data. 
function verify(proofBytes: Uint8Array, settingsBytes: Uint8Array): VerificationResult

​
test_wasm_module()

Tests if the WASM module is working correctly. 
function test_wasm_module(): string

​
get_version()

Returns the version of the verifier. 
function get_version(): string

​
Utility Functions

The LuminairUtils namespace provides several utility functions:
  • isValidProofBinary(proofBytes: Uint8Array): boolean
  • isValidSettingsBinary(settingsBytes: Uint8Array): boolean
  • getProofSize(proofBytes: Uint8Array): number

​
Types

​
VerificationResult

interface VerificationResult {
  readonly success: boolean;
  readonly error_message?: string;
}

​
DetailedVerificationResult

interface DetailedVerificationResult extends VerificationResult {
  verificationTimeMs?: number;
  memoryUsageMB?: number;
}

​
VerificationOptions

interface VerificationOptions {
  timeoutMs?: number;
  config?: VerifierConfig;
}

​
VerifierConfig

interface VerifierConfig {
  enableDebugLogging?: boolean;
  maxMemoryMB?: number;
}

​
Error Handling

The package may throw LuminairVerificationError in case of verification failures: 
interface LuminairVerificationError extends Error {
  name: "LuminairVerificationError";
  message: string;
  cause?: Error;
}
It’s recommended to wrap verification calls in try-catch blocks to handle potential errors gracefully: 
try {
  const result = verify(proofBytes, settingsBytes);
  // Handle successful verification
} catch (error) {
  if (error instanceof Error && error.name === "LuminairVerificationError") {
    // Handle verification error
  }
  throw error;
}
