Blockchain and energy-saving in same sentence sounds like oxymoron. But yeah "relatively" it probably would be. edit: checked out the whitepaper, its not even

Blockchain and energy-saving in same sentence sounds like oxymoron. But yeah "relatively" it probably would be. edit: checked out the whitepaper, its not even about the blockchain saving any energy itself. instead you save energy somewhere and record it on blockchain... for ... ?

It's not an oxymoron to anyone even remotely acquainted with crypto.

  Are there any non-Proof-of-Work blockchains in real use? (don't say ETH)

    Solana. It powers Audius which has ~300,000 monthly users.

      Solana is centralized - it recently completely froze because a single server was giving faulty data. This weakness has been known about for a long time, e.g. https://twitter.com/el33th4xor/status/1313425180635660288 https://twitter.com/el33th4xor/status/1313425180635660288

        The issue was an implementation bug afaict and from official responses. Solana is clearly BFT, unlike what Emin claims. To be fair, I don't expect Solana to be as centralised as other chains only for the reason that you need a gaming rig to run a consensus node. Solana is not centralised for the reasons you mention.

    Algorand is the only functioning proof-of-stake blockchain that I'm aware of at the moment, and it seems like it hasn't really seen much success.

  You'll have to back up that assertion, I'm afraid. Bruce Schneier refers to it as "enormous environmental waste" in https://www.schneier.com/blog/archives/2019/02/blockchain_and_.html https://www.schneier.com/blog/archives/2019/02/blockchain_an... .

    Proof of stake has been a thing since 2013 ...

      But it hasn’t really been adopted in a very successful manner, has it?
      - nathias 6y ago
        Adopted in a very successful manner? What does that mean? What a ridiculous standard. Technology exists, if you don't use it its not the fault of the tech. Its not hard to understand: "if X has green and non-green options, and you choose non-green, that doesn't mean you can claim X is non-green."

        Lack of widespread adoption provides circumstantial evidence that a technology might not be ready or practical yet.

  A central blockchain has not a lot more energy use than a regular database. It's the distributed trustless proof of work kinda blockchain that mindlessly burns up energy.

    A central blockchain is an oxymoron: a pointless waste of time. A distributed, trustless, permissionless data structure on the other hand is a useful thing to have for a small number of use-cases.
    - arcticbull 6y ago
      A small number of use cases, were pretty sure. So far the number of realized, actual extant use cases is between 0 and 1 depending on who you ask.
      - mikro2nd 6y ago
        Personally I'm aware of three that I'd count as good use-cases. Only one of those is a cryptocurrency.

        I'm aware of 0 including cryptocurrency but I'm sure you already knew that haha.
