  • We’re not comparing millions of DBs to a single blockchain. We’re comparing 1 DB to 1 blockchain instance. If you had millions of blockchains, you would use exponentially more energy for the same data vs. a normal database. Updating tables is not the same thing as hashing and validating every prior entry in the table.

    The only person here who doesn’t know what they’re talking about is you. If you took a standard DB (MySQL or Postgres, for example) and took that same information and stored it on a blockchain instead, you’d use far more energy on the blockchain and the issue would only get exponentially worse as the chain got bigger. Normal DBs don’t need to hash new entries or validate them against previous entries that are also hashed.




  • That’s one opinion. The other is that I like that all my devices operate seamlessly with each other and save me time and aggravation. I like that I can give my parents Apple products and not worry about them downloading things that might compromise their data or mess up their devices. The fact that limits exist is exactly what I like about Apple products. When I pick them up, they work.

    I say this as a current and previous owner of multiple PCs that I built myself and multiple Android devices. I used to love dicking around with all that stuff. Now I just need it to work and I need it to be secure and reliable. I get that with Apple products. I don’t get that with Linux, Windows, or Android anymore.

    DBs are not the same as a blockchain. A DB doesn’t have to hash all previous data before it every time the DB is written to. You can read and write to a specific spot in a DB without ever knowing anything else about the DB. With blockchain, inserts have to be successive and they have to reference every previous insert to validate that the entry series is unbroken. On top of that, for things like Bitcoin, every other client also has to validate it since the ledger is shared.

    There’s a reason blockchain is significant. Otherwise, why didn’t stuff like Bitcoin exist prior to it? Databases, in some for or another, have existed for decades. Blockchains are immutable, that’s why. The order of entries matters and validation is a requirement.
