<h2>LambdaWorks</h2><p>🚀 This project began by implementing the STARKs' prover. Lambdaworks covers critical aspects like finite field arithmetic, Merkle trees, and hash functions. We're excited to continue with elliptic curves and SNARKs. 🔧</p><p>🤔 What are STARKs? They're scalable, transparent arguments of knowledge—an essential cryptographic primitive. STARKs enable computational integrity by offering concise proofs of correct computations. The remarkable advantage of STARKs is that verifying these proofs is much faster than re-executing the program itself. ⚡️💡</p><p>Dive deeper into the Lambdaworks project: <a href="https://github.com/lambdaclass/lambdaworks" target="_blank">https://github.com/lambdaclass/lambdaworks</a></p><h2>Noir</h2><p>Noir is a programming language that makes it easy to write and verify zero-knowledge proofs.</p><p>Incorporating ZKPs into blockchain-based applications is still too hard, but Noir provides a familiar, Rust-based syntax to help onboard the next wave of developers into ZK applications.</p><p><a href="https://twitter.com/critesjosh_/status/1658487518713741314" target="_blank">Learn how to build a ZK voting app using 10 lines of Noir code</a></p><p><a href="https://t.co/3B8zf8aDum" target="_blank">Build ZK gaming applications (alongside the BattleZips team)</a></p><p><a href="https://twitter.com/Zac_Aztec/status/1645908026749247488" target="_blank">Use Noir to create innovative use cases like a Chemistry Simulator</a></p><p><a href="https://t.co/rjMILycYnE" target="_blank">Fork the Noir starter repo to get started using Noir, the easiest-to-use zkDSL</a></p><h2><br /></h2><h2>Orion</h2><p>What is Orion? Orion is a Cairo library for Validity ML. Leveraging Cairo and ONNX’s capabilities, Orion enables a transparent, verifiable, open-source machine learning inference framework.</p><p>Let’s break it down.</p><p>What is ONNX Runtime? - ONNX Runtime is a cross-platform machine-learning model accelerator, with a flexible interface to integrate hardware-specific libraries, which can be used with models from PyTorch, Tensorflow/Keras, and other frameworks.</p><p>Why Cairo? Cairo programming language enables developers to create provable and scalable computations associated with ML inference.</p><p>Orion leverages Cairo to guarantee the reliability of an inference, providing developers with a user-friendly framework to build complex and verifiable machine learning models.</p><p>Orion Goals:</p><p>1️⃣ Provide a runtime implementation for verifiable ML model inferences using STARKs.</p><p>2️⃣ Compliance with ONNX. interoperate between the ONNX format for a given trained model into a Cairo program using ONNX Cairo Runtime. We can easily represent any ONNX operators in Cairo code.</p><p>3️⃣ Tensor/ Linear Algebra computation (like Numpy) in Cairo 1.0.</p><p>4️⃣ Provide Orion APIs - Operators, Numbers, Performance - to enable  wide range of functions for effective neural network calculations, extended numeric capabilities, and performance-enhancing features.</p><p>5️⃣ Clear documentation with step-by step tutorials catering to beginners and advanced users alike.</p><p>You can now build your first Neural Network in Cairo 1.0 with Orion. "MNIST Classification with Feedforward Neural Network" is the first example in the Orion Tutorials repository.</p><p>https://orion.gizatech.xyz/resources/tutorials/mnist-classification-with-orion</p><p>In this tutorial you will 👇</p><ul><li><p>Train your model with Quantize Aware Training</p></li><li><p>Convert weights/biases to Cairo</p></li><li><p>Perform inference in Cairo with Orion🔸 The Orion Tutorials repository enables anyone to contribute by sharing their Orion tutorials and examples.🔸 To contribute, dive into the repo:</p></li></ul><p>https://github.com/gizatechxyz/orion_tutorials</p><p>🔸 And join the Giza Discord!</p><p><a href="https://discord.com/invite/FR3Cd88x6r" target="_blank">https://discord.com/invite/FR3Cd88x6r</a></p><p><br /></p><h2>Starknet</h2><p>What is Starknet? Starknet is a Validity Rollup that operates as an L2 on top of Ethereum. It gives developers the opportunity to build applications that scale without compromising composability and by inheriting the security of Ethereum. Wait! What?! How can that be possible? This is doable due to the use of STARKs, a secure and scalable proving system. To write smart contracts for Starknet, Starkware did some magic and created Cairo, a language that makes it easy to build STARK-compatible programs. Yes, you can code any type of program with Cairo and make it provable 🤯!  And thanks to Starknet you can make these programs run in a scalable and secure L2.</p><p>Goals:</p><p>1️⃣ Let your imagination fly, build without limitations. DeFi? NFTs? Games? You can write any type of program you want and still get the best security, and scalability for any use case. You just need to focus on the business logic.</p><p>2️⃣ Starknet has a very ambitious roadmap ahead and its users will be able to enjoy a fast and great UX. The next upcoming 0.12 upgrade will improve throughput, scale, and transaction latency. 100 TPS here we go!</p><p>3️⃣ Starknet supports account abstraction natively, you can create great UX for your users. Now accounts are just smart contracts that can be modified and leveraged for composability.</p>
