Celebrating our 2025 open-source contributions

Trail of Bits engineers contributed over 375 pull requests to 90+ open-source projects in 2025, including work on cryptography libraries, the Rust compiler, and Ethereum tools. Rather than forking or locally patching dependencies when they encountered bugs or needed features, they contributed fixes upstream so the entire community could benefit. Key contributions included adding identity monitoring to Sigstore's Rekor (a transparency log for software signing), improving Rust's linting tools, developing a new ASN.1 API (a standard for encoding data structures) for Python's cryptography library, and optimizing the Ethereum Virtual Machine implementation.
