**Introduction:**

We're happy to introduce our proposal aimed at fortifying the Polkadot ecosystem's decentralization and resilience by optimizing protocol compliance testing. Currently, Polkadot boasts five diverse host implementations—Polkadot by Parity, Smoldot by Smoldot, Kagome by Quadrivium, Gossamer by ChainSafe, and Fruzhin by LimeChain. While this diversity enhances decentralization, it also poses challenges, particularly regarding protocol compliance and robustness.

**Proposal Overview:**

Our proposal stems from extensive research highlighting the need for a comprehensive protocol compliance testing suite. We envision leveraging Zombienet—a framework designed to power host-agnostic Host Conformance Tests—to address these challenges effectively. By crafting test cases and integrating with Zombienet, we aim to establish a robust testing framework ensuring protocol compliance across all implementations.

**Here is how it’s gonna go:**

We'll kick off by crafting test cases, covering key functionalities like State Trie, Trie Host API, and SCALE modules, and creating host-agnostic test fixtures. Next, we'll build a custom Host Conformance Runtime, extending Polkadot's runtime and integrating it with Zombienet for automated testing. Finally, we'll focus on detailed documentation to ensure transparency and facilitate community involvement.

Our dedicated team, comprising a full-time Blockchain Developer, a full-time QA Specialist, a part-time Tech Lead, and a part-time Project Manager, is committed to delivering results within a 10-week timeframe. We believe this initiative will pave the way for enhanced protocol compliance and resilience within the Polkadot ecosystem.

For further details, please refer to our proposal document We're excited to contribute to the continued growth and decentralization of Polkadot and welcome feedback and collaboration from the community.

**Company background:**

LimeChain is a software development company founded in 2017. Positioned to handle end-to-end product development with the capability to manage projects from conceptualization and design to the complete implementation of a certain product. LimeChain specializes in blockchain technology, with an emphasis on developing blockchain-related and infrastructure solutions.
