  It’s not complicated at all. It’s basic database access management and it’s been a thing for decades without issue. If external access is required then those parties are given restricted access appropriate for their job and their actions are logged in the audit log in case any inappropriate actions were taken by them and need to be reviewed/reversed. These are solved problems and blockchain adds nothing there. The only case that blockchain helps is in a system where you have a large number of random participants and you want transactions to be enforced by work done/computing power or stake. This is why cryptocurrency has been the only practical use case for blockchain, with the word “practical” doing a lot of work, hence the diagram in the post we’re all discussing.

    If external access is required then those parties are given restricted access

    So a human needs to get involved.

    inappropriate actions were taken by them and need to be reviewed/reversed.

    Lack of finality slows processes.

    These are solved problems and blockchain adds nothing there.

    Two improvements/use cases given above.

    The only case that blockchain helps is in a system where you have a large number of random participants

    I.e. Access without human authorisation

    and you want transactions to be enforced

    Finality.

    This is why cryptocurrency has been the only practical use case for blockchain,

    Supply chain tracking

    Royalty payments

    Renewable energy tracking

    Ticketing

    Etc.

      A human only needs to get involved for manual database changes. The vast majority of database transactions are carried out by code. The same would be true for blockchain. Again, it’s not magical. I will ask you once again: how do you think a blockchain would be used to improve this? The blockchain as used by bitcoin allows everyone the same access, but uses compute power as a consensus mechanism in the hopes that statistically most participants would be running the same code to keep things legitimate.

      How do you propose a bank does this internally? You’ve yet to answer this question I asked a few posts before and instead opted to list proposed use cases like a brochure advertising blockchain. This is what I usually see with blockchain evangelists, repeating talking points that they themselves don’t understand. Like seriously, what is “renewable energy tracking” supposed to mean?

        human only needs to get involved for manual database changes.

        So how would you on-board a new user?

        The vast majority of database transactions are carried out by code.

        Transactions yes. Access no.

        how do you think a blockchain would be used to improve this?

        Access is controlled by public key and security is self administered. No central authority chooses who can join.

        The blockchain as used by bitcoin allows everyone the same access

        Exactly. The power of publi/private key cryptography.

        uses compute power as a consensus mechanism

        Compute power is not required for blockchain and has nothing to do with private keys.

        How do you propose a bank does this internally?

        Issue private keys to all employees. Use a protocol that doesn’t require PoW.
