    Nah. the commenter above is just wrong. It’s just that anyone who isn’t selling bullshit uses their real name- Merkel trees - which are fundamental to modern software development (git, zfs, nix, nosql).

      That’s a similar but different concept. Blockchain adds a way to determine consensus of the correct tree. While git is distributed, it’s generally not trustless, there’s generally a trusted version of the repository.

        what? Git is very much distributed and while you can have a main branch, you can set as many up streams as you want and merge things sideways.

        It’s trust less in the sense that commits can’t be easily forged and are signed with cryptographic keys and identities-- as in, I don’t have to trust that the source code is genuine since I can verify the commit history myself.

        Consensus is just a pull request.

        That wiki article literally lists Bitcoin and Ethereum as implementations of Merkel trees.

          I’m pretty sure being able to verify that the person responsible for a push is an actual maintainer is the opposite of trustless.

            How is it any different than verifying that a transaction occurred?

            How is a trusted repository different from a hard fork?

            Isn’t “proving someone is a maintainer” just an IRL proof of stake?

              With a centralized trust source (bank), you ask for the records.

              How is a trusted repository different from a hard fork?

              Because you check who owns and maintains it. A notable example was with Simple Apps for Android, earlier this year the main repo was sold to a company. Trust was lost, thus a fork was created to keep the original stuff.

                Right, but isn’t the “main chain” of Ethereum based on a similar principle wherein it’s the main chain because it’s the one the devs use?

                What about BTC vs BTC lightning.

                I’m genuinely failing to see a distinction here, and, again, the wiki article says that blockchains are special cases of Merkle trees.

                  No clue, I don’t keep an eye on that, I’m partially aware that there are several similar forks (and eth classic was a result of scammy shenanigans) but, afaict, none try to pretend they’re the “real” ethereum.

                  I’m genuinely failing to see a distinction here

                  A distinction between trust and trustless? Because my initial point was that git isn’t trustless, because it works just like any other online system that requires a login, where a central server/database checks if the user sending inputs was properly identified by some mean (password, cryptographic key, something else). Implementing a Merkle or any other hash tree doesn’t make something trustless

                    does git require authentication with a central server? I know that’s common practice and true of github, but my recollection was that it was meant to fix the problem of distributed kernel development via an email listserv in the early 2000s. This stack exchange post discusses how it’s not really centralized
