I had mentioned at the IETF 118 meeting that we had done something called Difference Based Content Networking using aggregated signing objects (a type of manifest) and diffs to encode new versions. We explored several types of diffs, from byte patches, to segment patches, to hash-based de-dup style, and finally to manifest patches (i.e. don't patch the data, patch the manifest). Here is the white paper on that technology. The work was originally done in 2014. The white paper supported a patent [1], which appears to be EU, JP, and CN filings, which is currently assigned to Cisco. https://arxiv.org/pdf/2311.03831.pdf [1] https://patents.google.com/patent/EP2975825B1/en
