    You need to explain that, though they are generally rich, it’s not unusual for unheard of princes to occasionally fall on hard times and have their fortunes compensated until they are able to pay a ransom to get a corrupt bank or government to release their vast wealth back to them AND that they are almost always grateful to anyone who assists them in paying that ransom.

    Oh wait, sorry, wrong scam.

    Wouldn’t you find it useful to be able to prove that you paid for something? When you buy an NFT, you’re buying just that: the ability to prove that you bought it. And sometimes it even comes with a copy of an image or a spaceship you might just be able to use in a video game or just hold on to until we develop the technology to live in video game spaceships and you sell it for massive profits!

    Relationships are like the blockchain.
    There’s no trusted, central database of all relationships that determines what is or isn’t cheating.
    That trust is negotiated in each interaction.

    Marriages follow the traditional method of a chain of trust. There is a central database that lies with the government or the church, and everyone decides which database they want to trust.

        Congratulations, now your trust relies on your subject never becoming important enough that someone bothers to run 50%+1 of the nodes in your network which means only very, very large subjects (or ones where trust wasn’t very important in the first place) ever even have a chance of that not happening.

            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.

        Is it easier to establish a source of trust? With blockchain trust lies in the protocol and in the node operators who make decisions about how to operate their nodes. Running a node isn’t extremely difficult. Running a financial institution is difficult.

        Apparently, it can be very secure. If “pieces” of a secure key are stored in multiple places, for example, only changing one link in the “chain” means it won’t match with the others. They ALL have to be changed at the same time, which is virtually impossible to do in secret.

              This would just create a fork in the blockchain where 51% of the network doesn’t match the correct state of the blockchain that the 49% have. The 49% would effectively stop working because they could never validate the transactions that the 51% takeover has falsely created. The node operators of the 49% of the network would need to reach consensus for how to deal with the problem, but essentially they would just adopt code that ignores the 51% data, so they could continue to process blocks of transactions. Without manual intervention the 49% would be frozen. The 51% is just fake, they haven’t really changed anything because every real node operator would know it’s false data.

        Essentially, verifiability (the token exists on the blockchain), de-duplication (each token can only exist once on the blockchain), and proof of ownership (only one account number can be associated with each token on the blockchain). There’s nothing wrong with this idea in a technical sense and it could be useful for some things.

        But… the transaction process is computationally expensive. For the transaction to be trustworthy, many nodes on the blockchain network must process the same transaction, which creates a whole bunch of issues around network scaling and majority control and real-world resource usage (electricity, computer hardware, network infrastructure, cooling, etc).

        And beyond that, the nature of society and economics created a community around this unregulated financial market that was filled with… well, exactly the kind of people you’d expect would be most interested in an unregulated financial market - scammers, speculative investors, thieves, illegal bankers, exploitatitive gambling operators, money launderers, and criminals looking to get paid without the government noticing.

        The technology can solve some interesting problems around verifying that a particular digital file is unique/original (which can be useful, because it’s extremely easy to make copies of digital information) but it creates a long list of other problems as a side effect.

          Almost every single non-theoretical problem that blockchains solve is something we’ve already solved. And most of the problems you could solve with a blockchains are severely limited by data-size limitations.

          It would be amazing if I could decentrally store, say, a movie or videogame on a blockchain. Then, I could sell access tokens, would the owners could resell as they wanted. That’s a GREAT way to use blockchain tech, because people would always have access, and they could use or sell the keys as they wanted. It doens’t work though, because in the real world, that movie doesn’t fit on the blockchain, it’ll just be a link the a secondary source, and the whole thing falls apart.

          And that’s really the problem. Blockchains have a lot of nifty uses, but it almost always immediately falls apart around the edges, where it touches on non-blockchain tech, or, even worse, physical objects.

          Yea the idea there is that with it being decentralized, it has an unedited history. So if each block added to the chain is a new transaction, you can see previous agreements. Being decentralized also means that it’s public record and everyone can see the contract/agreement/transaction.

In reality it becomes far, far easier because you’ve now opened up a gigantic attack surface that you have no control over, and made both systems of verification worth less.
