bitDEP

bitDEP is a protocol and reference implementation for encoding, transporting, and validating bit-level dependencies in distributed systems. It aims to provide a compact representation of how data bits depend on one another, supporting reproducible builds, data integrity, and efficient streaming of dependency graphs. The scope includes software packaging, content distribution, and data pipelines where precise provenance matters.

The format encodes dependency graphs as a directed, bit-oriented stream. It relies on content-addressable identifiers, cryptographic hashes, and Merkle-like authentication to enable verification without re-executing computations. A header specifies version, encoding mode, and policy constraints; the payload carries edges, version bounds, and optional metadata. The protocol supports streaming processing, incremental updates, and offline verification.

Implementation and ecosystem: Open-source implementations exist in multiple languages, with tooling designed to integrate into build and packaging workflows. The design emphasizes a small, extensible schema and backward compatibility across major versions to aid interoperability.

Adoption and uses: BitDEP is employed by organizations seeking reproducible provenance and supply-chain security, for packaging assets, distributing verifiable dependencies, and validating deployments. It is often used alongside content-addressable storage and digital signatures.

Limitations: As a niche protocol, adoption varies and interoperability with established tools remains in progress. Performance depends on graph size, verification requirements, and the efficiency of the underlying storage backend.
