# Open Source projects Blocktorch is committed to advancing the open-source ecosystem, particularly in the realm of web3 data engineering. If you are a developer you are warmly invited to contribute to the projects, which aim at enhancing accessibility and utility within the web3 data space. Currently, we have published two open-source projects: 1. **Decoder Service**: Designed to convert web3 data into formats that are easy for humans to read, this tool is crucial for developers working in blockchain data analysis and interpretation. [Repository](https://github.com/blocktorch-xyz/decoder) | [Blog Post](https://medium.com/@blocktorch/decoding-web3-data-into-human-readable-format-6804669b6db5) 2. **Batch Decoder**: This project focuses on tracing transactions between Layer 1 Blockchains and Optimistic rollups as Layer 2 solutions, addressing a critical need for better interaction and understanding of cross-layer transactions. [Repository](https://github.com/blocktorch-xyz/optimism-batch-decoder) | [NPM Package](https://www.npmjs.com/package/@blocktorch/optimism-batch-decoder) | [Blog Post](https://medium.com/@blocktorch/the-missing-link-between-l1-and-l2-transactions-on-optimism-b119f61d0464) Both projects are meant to help decode, make sense and work with blockchain data. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.blocktorch.xyz/contribute/open-source-projects.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
