What is Web2 Proxy?

The Web2 proxy system allows you to make HTTP requests through the Demos network. Requests are verified by a network of attestation nodes, ensuring data integrity and reliability. The system provides:
  • Secure proxy requests through the Demos network
  • Session-based request handling
  • Support for all standard HTTP methods
  • Custom header and payload support

​
Basic Example

import { Demos } from "@kynesyslabs/demosdk/websdk"

// Connect to demos and set up identity
const demos = new Demos()
await demos.connect("http://localhost:53550")
await demos.connectWallet(mnemonic)

// Create and use proxy
const dahr = await demos.web2.createDahr()
const response = await dahr.startProxy({
    url: "https://api.example.com",
    method: "GET",
})

​
Key Features

  • Session Management: Each proxy request is handled through a dedicated session
  • Method Support: GET, POST, PUT, PATCH, DELETE
  • Custom Headers: Add your own headers to requests
  • Payload Support: Send data with your requests
  • Authorization: Include authorization tokens when needed

​
Choosing Between DAHR and TLSNotary

The Demos Web2 system offers two complementary methods for web attestation:

DAHR

Fast proxied requests with hash attestation. Best for general API calls where speed matters. Response hashes are stored on-chain.

TLSNotary

Cryptographic proofs from TLS sessions. Best for confidential data requiring verifiable attestation with selective disclosure.
