Certificate transparency is a permissioned blockchain (a merkle hash tree), ran by a group of trusted organizations and observed by third party monitors ("validators"). Your browser probably queried that blockchain when you opened hackernews.
- tsimionescu 4y agoIt's a Merkle hash tree. You can call that a blockchain if you want, but we already have a much older and more specific term for it: Merkle hash tree.
- dbrgn 4y agoSure, I just wanted to point out that building merkle hash trees, or blockchains, or whatever you want to call it, isn't "all rubbish". There are some valid use cases.
- tsimionescu 4y agoMy point was that people who talk about blockchain typically refer to something other than a Merkle hash tree - they refer to a hash tree plus some consensus mechanism for trustless addition. I don't know of a term other than "blockchain" that can be used to refer to this concept.
- mnd999 4y agoIt doesn’t even have to be trustless, some of this crap is using RAFT (for speed), the assumption being that the participants are all trusted.
