package for tlsn notary proof verification in wasm
npm install zknotary-verifierThe Verifier component of zkNotary is a crucial tool for validating the authenticity of data notarized by the Prover. It's a WebAssembly module compiled from Rust, using wasm-pack, and is designed for use within JavaScript applications.
- WebAssembly Compilation: The Rust code is compiled into WebAssembly, making it suitable for integration in web environments.
- Single Public Function - verify: Exposes a function that takes proof_json and notary_pubkey as inputs and returns a plain-text notarization of the original interaction with a web server.
- Digital Signature Validation: Validates that the proof was digitally signed by the notary server, ensuring authenticity.
- Rust
- Cargo
- wasm-pack
Note: This project requires a clang version newer than 16.0.0 to compile ring to wasm. If not, you will run into warning: error: unable to create target: 'No available targets are compatible with triple "wasm32-unknown-unknown"'
- src/lib.rs: This is the main library file for the Verifier.
- src/utils.rs: This file contains utility functions used by the Verifier.
- pkg: Autogenerated directory where the npm package code lives.
- examples/node: A sample node application that showcases how to use the verifier package. For more information see the sample application's README file.
1. Install wasm-pack
``sh`
npm install -g wasm-pack
2. Optional: For Mac users with a version of clang older than 16.0.0, you can use Homebrew to install llvm and then use it to compile the project.
`sh`
brew install llvm
echo 'export PATH="/path/to/your/newly/installed/llvm/bin:$PATH"' >> ~/.zshrc
source ~/.zshrc
3. Build the wasm project
`sh`
wasm-pack build --target nodejs
This creates a new pkg directory with the wasm package ready to publish to npmjs.com.
4. Publish your npm package
`sh``
cd pkg
npm publish
