> Doesn't the bitcoin blockchain provide the same service roughtime does, and without the centralized authority (cloudflare in this case) problem? Oh god, I can only imagine the horror of trying to use Bitcoin as a public notary service. The whole point of an append-only data structure is that you can replicate it and if someone's node is being dishonest, they cannot do so silently. You'd be better off with something like Trillian (and/or Certificate Transparency; see https://wiki.mozilla.org/Security/Binary_Transparency for more). I wrote something in this vein called Chronicle: https://github.com/paragonie/chronicle Main selling point? It's not a blockchain, but it solves a lot of the problems that cause people to point to blockchain solutions. My goal with Chronicle is to ween the industry off of poorly thought-out blockchain projects

> I don't understand the common sentiment on HN that "you don't need a blockchain, just an append-only decentralized database with Merkel root logs", as if that's something easy to build. In my case, this sentiment accompanies an implementation in the form of an easily-deployable open source microservice. https://github.com/paragonie/chronicle If it's too hard for people to build, they can use what I wrote. > What is this hypothetical non-blockchain, where are you going to get it, and why not just use a blockchain if that's what you need? That's the tx/s limit on Bitcoin today? I can do hundreds of writes per seconds to Chronicle on a modest VM without sweat. This is possible because it's centralized, albeit supports mirroring (i.e. replication) and cross-signing.
