About

Scroll is a zero-knowledge rollup built to scale Ethereum. We're committed to Ethereum's ethos, and like to call ourselves the community-first zkEVM. If you’re experienced in building on Ethereum, your code, dependencies, and tooling work with Scroll out of the box. This is possible because our network is compatible with EVM bytecode and designed to feel just like developing on Ethereum.

Digital privacy is a human right. We want to see your best use of ZK to build out a novel privacy use case on Scroll. This could be a standalone project, or a unique way of connecting the building blocks already in our ecosystem. Work with identity (i.e. Anon Aadhaar, EAS), Defi (i.e. Uniswap, Aave), or established ZK stacks (i.e. ZK Email, Semaphore). Building with Noir using client-side proving and on-chain verifying is a great way to get started.

Qualification Requirements

- Projects must be deployed on the Scroll Sepolia testnet and verified using the Scrollscan Block Explorer

Scroll scales Ethereum and the EVM, but applications still have opportunities to improve accessibility for users on Scroll. This could be through experimenting with DA layers (i.e. Avail), proof generation markets (i.e. Sindri), or aggregating and verifying off-chain work for use cases like gaming. We want to see your wild ideas for bringing new possibilities on-chain by leveraging ZK to verify things that aren't feasible to do on-chain.

Qualification Requirements

Projects must be deployed on the Scroll Sepolia testnet and verified using the Scrollscan Block Explorer.

About

Sindri is modernizing the ZK DevOps and proving stack providing builders with accessible, streamlined infrastructure. It was built by developers, for developers after witnessing firsthand the difficulties with iterating and shipping ZK apps. ZK dev teams will find engaging with Sindri is very similar to how you might engage with Infura or Stripe via API calls that can be built right into application logic or the browser. The Sindri API offers out-of-the-box serverless proving deployments, adaptable support for your favorite proving systems with minimal refactoring required, built-in acceleration, and SDK/CLI tooling to deliver a phenomenal developer experience. Develop and deploy amazing ZK applications in minutes instead of weeks or months. We've built Sindri from a place that respects the builders and coders who need accessible, reliable infrastructure solutions to share their life work. We're excited to share it with you. To use Sindri, you will need an API key. Please request in Discord Circuit Breaker lobby (@stasia), by e-mail at hello@sindri.app or message us on telegram at @etainos

Please request in Discord Circuit Breaker lobby (@stasia), by e-mail at hello@sindri.app or message us on telegram at @etainos Use your creative power to build a ZK submission leveraging Sindri’s API and versatility. Your project should utilize one of Sindri's supported proving systems, including Gnark, Noir, Halo2, and Circom, to build something truly unique.Rollups, coprocessors, interoperability solutions, payment gateways, DePIN, and more can all leverage Sindri for scalable, elastic-proof generation. Our Python, Javascript, and Typescript SDKs and tooling allow you to build proving logic directly into the application layer, streamlining access to Sindri’s scalable, accelerated infrastructure stack. In turn, developers can build with large circuit structures and unexpected, high-volume request spikes, which are often challenging in ZK applications. Looking for a starting point? Browse the How-To Guides in our docs for examples of: - Circom + Python + Sudoku - Gnark + Javascript + String Compression - Halo2 + Rust + Floating Point Arithmetic - Noir + Javascript + PageRank**To use Sindri, you will need an API key.

Best use case with Avail Light Client embedded$2,000
Up to 2 teams will receive $1,000
The Avail light client plays a vital role in ensuring the availability and correctness of data within the Avail network. Avail light client (LC) lets you interact with Avail blockchain without requiring a full node and without trust assumptions towards remote peers. This is accomplished by Data Availability Sampling (DAS) by the LC enabled by the use of KZG commitments in Avail's block headers. The light client is capable of downloading and verifying application-specific data submitted to Avail, which can be queried using the light client API. The light client exposes an HTTP API that enables users to query the status, confidence, and application data for each processed block. Utilize and embed Avail's Light client in your project. Build any use case you deem is required for the rollup-centric future! Project ideas include (not limited to): - Build/Integrate a non-substrate wallet that connects to Avail and has embedded support for Avail's Light Client features. - Fetch data from your rollup/appchain with your embedded Light Client and do some magic with it ✨ - Visualize rollup data (or a rollup explorer) powered by the Light Client. - Use the power of the Light Client's data availability sampling properties and the LC p2p (DHT) network.

Qualification Requirements

Only Eligible projects will qualify for the prizes: - Embedding the Avail Light Client in your use case in a meaningful way (with utility) is mandatory - Needs to be a new project.
