Boxo is an open-source library designed for developing IPFS applications and implementations using Go. It offers a curated collection of high-quality components for tasks such as content routing, data transfer, and managing content-addressed data, facilitating both interaction with public and private IPFS networks and reuse of critical IPFS functionality like Kademlia DHT and Bitswap. Serving as a foundational toolkit, Boxo does not encapsulate all IPFS components but provides a robust, cohesive interface for common scenarios. It is particularly ideal for developers looking to innovate or enhance systems within the Go ecosystem. Constructed with a commitment to high maintenance standards and ease of use, Boxo accepts contributions that align with its quality criteria. Boxo underpins the popular IPFS implementation, Kubo, ensuring its components are well-vetted by extensive real-world usage and community insights, thereby aiming to simplify IPFS development and foster broader innovation within the network.
