Dear Blockcerts community,
I learned about the Blockcerts project recently, and wanted to mention some work my group at EPFL has been doing on next-generation blockchain infrastructure that might be of particular interest here. In short, a paper we’re presenting at USENIX Security next month introduces SkipChains, a collectively signed blockchain structure that could in principle make blockcerts verifiable offline or peer-to-peer, while preserving the decentralized security of the blockchain model (i.e., no single point of failure or compromise). I just published up a blog post on this topic:
How Do You Know It’s On the Blockchain? With a SkipChain.
Hope you find the blog post and/or paper relevant and interesting - any feedback/discussion would be welcome. In the longer term, if there’s interest, my group and I would be happy to work with you all to get something along these lines deployed, if there’s potential interest in having an offline-verifiable blockchain as a complement or alternative to Bitcoin-based certificate registration.
