How to install Rusty Kaspa on Windows?

Install Git, Protobuf, LLVM-15.0.6, and set environment variables like LIBCLANG_PATH. Rename LLVM_AR.exe to AR.exe to fix build issues, then install Rust, wasm-pack, and clone the repo. Full steps are in the README's Windows section.

What's the difference between Rusty Kaspa and the original Golang Kaspa node?

Rusty Kaspa is a drop-in replacement written in Rust, offering performance and safety benefits, with added features like wRPC and WASM SDK. It's the recommended node, but the Golang version might be simpler for those familiar with Go.

How to run a Kaspa node for mining?

Start the node with --utxoindex and enable wRPC via --rpclisten-borsh, then use the beta Stratum Bridge. Note that the bridge is in beta, so check Discord for support and follow bridge docs for setup.

Can I use Rusty Kaspa for web development?

Yes, via the WASM SDK which provides JavaScript/TypeScript libraries for web and Node.js. Build scripts like ./build-web generate release packages, and documentation is available online for integration.

Is the Stratum Bridge stable for production mining?

No, it's in beta with limited support through Discord. Bugs and feature requests should be filed as GitHub issues prefixed with [Bridge], so it's not recommended for critical production use yet.

How to benchmark Kaspa DAG performance?

Use the Simpa simulator with commands like cargo run --bin simpa -- -t=200 -d=2 -b=8 -n=1000 to generate blocks with transactions and delays, then analyze validation times as per the benchmarking section.

What is Kaspa?

Rusty Kaspa is the reference implementation of a Kaspa full-node and related libraries written in Rust. It serves as a drop-in replacement for the original Golang node and is the recommended software for running a node on the Kaspa network, which is an open-source blockchain platform focused on scalability, speed, security, and decentralization.

Target Audience

Blockchain developers and enthusiasts who want to run a Kaspa node, contribute to its Rust implementation, or build applications on the Kaspa network using its WebAssembly SDK.

Value Proposition

Developers choose Rusty Kaspa for its high-performance Rust implementation, which offers safety and efficiency, and its comprehensive feature set including a WebSocket-framed RPC subsystem (wRPC), multi-platform builds, and a WebAssembly SDK for web and Node.js development.

Overview

Kaspa full-node reference implementation and related libraries in the Rust programming language

Use Cases

Best For

Running a full-node on the Kaspa mainnet, testnet, or devnet with support for UTXO indexing for wallet functionality.
Developing web or Node.js applications that interact with the Kaspa blockchain using the provided WebAssembly (WASM) SDK and JavaScript/TypeScript libraries.
Benchmarking and testing Kaspa's Directed Acyclic Graph (DAG) generation and validation using the included in-process network simulator (Simpa).
Connecting mining hardware to the Kaspa network via the beta Stratum Bridge for mining operations.
Building command-line tools or wallets that interface with the Kaspa node using its RPC subsystem (supporting both Borsh and JSON protocols).
Experimenting with non-standard consensus parameters in development or test environments using the override parameters feature.

Not Ideal For

Projects targeting blockchains other than Kaspa, as this is a Kaspa-specific full-node implementation.
Environments where quick, simple setup is critical, due to complex build dependencies like Protobuf and LLVM on Windows and macOS.
Applications needing lightweight client access without running a resource-intensive full node, since it requires UTXO indexing for wallet functionality.

Pros & Cons

Pros

High-Performance RPC

Integrates a WebSocket-framed wRPC subsystem with Borsh and JSON encoding, enabling efficient communication for both inter-process and web-based interactions, as detailed in the wRPC section.

Cross-Platform Builds

Supports builds for Linux, Windows, macOS, and Docker with multi-architecture images, including scripts for multi-arch Docker builds, making deployment flexible across environments.

WebAssembly SDK

Provides WASM components for developing web and Node.js applications with JavaScript/TypeScript, backed by release builds and documentation, facilitating blockchain integration in web projects.

Built-in Simulation

Includes the Simpa in-process network simulator for testing and benchmarking DAG generation and validation, allowing developers to experiment with block parameters and delays.

Cons

Complex Build Setup

Installation requires multiple dependencies like Protobuf, LLVM, and specific toolchain configurations, with noted issues on Windows for AR setup, making onboarding cumbersome.

Beta Mining Support

The Stratum Bridge for mining hardware is labeled as beta, with support limited to Discord channels, indicating potential instability and incomplete features for production mining.

Kaspa-Specific Lock-in

As a reference implementation for Kaspa, it offers little utility outside this blockchain ecosystem, tying development and contributions to Kaspa's network and adoption.
