RAYSTYLUS
Experience the first fully on-chain ray tracer with AI-powered aesthetics built with Rust and WebAssembly. Neural Network inference directly on the Arbitrum blockchain.
The 3D graphics you create are rendered on the blockchain using Dot Product, Normalization, Quadratic Formula - powered by on-chain ML.
UNDER THE HOOD: THE COMPUTE ENGINE
RayStylus is not a contract; it's a Proof-of-Compute architecture that redefines on-chain performance and user experience.
Rust Logic
Vector math & ray tracing algorithms written in Rust.
WASM Compilation
Compiled to WebAssembly for near-native execution speed.
Arbitrum Stylus
Executed on-chain at 10x-100x lower gas cost than Solidity.
Computational Dominance
RayStylus executes massive computational throughput running thousands of vector algebra and quadratic equations per transaction. This is a far heavier benchmark than single formula financial models, proving Stylus's ability to handle the most demanding physics and array processing tasks.
Zero-Lag Interactive Studio
We defeated blockchain latency. By utilizing instantaneous `eth_call` simulation, users can adjust Color, Position (XYZ), and Background in real-time. This is the first true Zero-Lag UX in a dApp, proving Stylus can deliver Web2 standards of interactivity.
Why It Matters
Bringing ray tracing logic into smart contracts requires a paradigm shift in architecture.
The Problem
Why Is Heavy Computation Always Off-Chain?
- Expensive Costs: EVM is not designed for complex floating-point math. Simple 3D rendering can cost thousands of dollars in gas.
- Array Limitations: Large pixel array manipulation often hits block gas limits.
- Off-chain Reliance: Most NFTs only store URLs to IPFS/S3, not the actual image data.
The Solution
StylusCanvas: Native Rust RayTracer
- Stylus Efficiency: We move vector, shading, and lighting logic to Rust Smart Contracts compiled to WASM.
- 10-100x Cheaper: Instant computation with a fraction of the cost of traditional EVM.
- True On-Chain: Images are generated deterministically by contract code, forever on the blockchain.
Why Neural Network on Blockchain Matters
Combining AI with verifiable on-chain computation creates a new paradigm: trustless AI inference with deterministic results.
AI on Blockchain
First-ever 3→4→2 neural network running on smart contracts. AI inference without off-chain APIs or centralized servers.
GPU-Like Performance
Fixed-point i64 arithmetic enables fast matrix operations. 4 hidden neurons with ReLU activation and sigmoid output layer.
Deterministic & Verifiable
Every ML inference result is on-chain and immutable. No randomness, no server inconsistency—pure mathematics.
Aesthetic Generation
Train ML model off-chain, deploy weights on-chain. Users input 3 parameters (Warmth, Intensity, Depth), get deterministic RGB colors.
Minimal Footprint
28 weights + 6 biases = ~1KB of data. Efficient enough to run millions of inferences within gas constraints.
Trust Minimized
No centralized service controlling aesthetic generation. Model weights are public, auditable, and unchangeable on-chain.
Neural Network Pipeline
1000 Samples Training
Trained on synthetic data: Warmth × Intensity × Depth → RGB sphere color outputs with noise to improve generalization.
Fixed-Point Conversion
Weights & biases converted to i64 fixed-point (scale 10^18) for Rust contract. Maintains precision across blockchain.
On-Chain Inference
Layer 1: 3 inputs → 4 hidden (ReLU). Layer 2: 4 hidden → 2 outputs (Sigmoid). Free VIEW function, no gas required.
Aesthetic NFT Minting
After inference, render raytraced sphere with predicted colors. Store rendering params (21 bytes) on-chain permanently.
Why This Changes Everything
Before: AI services were centralized. Users had to trust servers. Models could be changed without notice.
Now: ML runs on blockchain. Weights are immutable. Every inference is verifiable. Trustless AI for the first time.
RayStylus + MNN: Raytracing (geometric computation) + Neural Network (aesthetic inference) = complete on-chain 3D graphics with AI. No servers. No APIs. Pure blockchain.
