Previously, we reviewed Google’s Certificate Transparency efforts, and observed that while it does not prevent MITM attacks, it might detect at least some of them. We compared it to blockchains, and described what a Decentralized Public-key Infrastructure (DPKI), which uses blockchains, might look like.
