Mining too

• AmericanChopper 8y ago
  Mining simply refers to rewarding nodes that work to verify transactions. A blockchain can exist without distributed verification, and without mining.

    Example?
    • AmericanChopper 8y ago
      Example of what? You’re quite clearly thinking about a mine-able crypto currency, of which blockchain tends to be an underlying data structure. You want a blockchain without mining? You could set one up in a couple of minutes. https://aws.amazon.com/blockchain/ https://aws.amazon.com/blockchain/ Do you want a real world example? It seems to be getting some use in supply chain management. https://www.ibm.com/blockchain/industries/supply-chain https://www.ibm.com/blockchain/industries/supply-chain A blockchain is just a type of data structure. Cryptocurrencies use blockchains, but mining, trustless distributed consensus, fault tolerance, and all these other things are features of cryptocurrency implementations, not essential elements of blockchains.

        Nobody is actually using 'blockchain' in production except to tick the buzzword box. That IBM page is just a puff piece and they have no clients using anything like that.
        • AmericanChopper 8y ago
          Volkswagen quite publicly use that very solution from IBM, and there’s numerous other examples of it being used in supply chain management, which absolutely isn’t the only useful application of blockchains. It’s not even clear if you know what a blockchain is, and your comments on its usefulness are just as extreme and misinformed as the evangelists who say it can be used to solve any problem under the sun.

            Link me to the VW thing please? Last I checked there was literally no reason to use blockchain outside of cryptocurrencies since you get the same benefits just using GIT.

Looks like they want to use it to lower traditional auditing costs in developing countries. Not sure how the blockchain tech is supposed to help tracking materials or establish trust in such an environment but that's not really my field - presumably it adds a component of different people creating a digital paper trail that's harder to manipulate. That's an application compliance people in a few sectors seem to like these days, guess we'll see if it actually makes sense over traditional efforts in N years.

              Here you go. https://www.coindesk.com/volkswagen-to-track-minerals-supply-chains-using-ibm-blockchain https://www.coindesk.com/volkswagen-to-track-minerals-supply... > Last I checked there was literally no reason to use blockchain outside of cryptocurrencies since you get the same benefits just using GIT. How does the data structure of a git repo differ from a blockchain? The only difference I can see is in how it’s used. A blockchain wouldn’t have more than one permanent branch.

                The project it links to is not used in production yet, it's just a pilot at this stage.
