  It's not particularly intriguing, he is trash talking the competition.

    that it's relatively self aware, in particular about energy consumption concerns, is mildly intriguing i think
    • fsckboy 2y ago
      the global warming consensus dominates the public discourse, the idea that somebody involved in crypto is not aware of energy consumption is a bit absurd

      What's wrong with energy consumption? I think you might be confusing it with greenhouse gas emissions.

        How's the electricity you're using produced? ;)
        • kragen 2y ago
          are we talking about people doing bitcoin mining or hash cracking? bitcoin mining is an extremely competitive business of finding the cheapest sources of energy and mining hardware; because the cheapest energy sources are all renewable, mining bitcoin with fossil-fuel-produced power is unprofitable. so the electricity we're using to mine bitcoin is mostly solar, wind, and hydroelectric as for the cracking, i don't think we know anything about where it was done or how much energy was needed, but if the energy cost was significant, i'd expect the solver to have done it somewhere where energy was cheap

            Finding the “cheapest” energy to do useless work, is still wasteful pollution.
            • kragen 2y ago
              'pollution'? actually no. why would you even think that?
          • BobAliceInATree 2y ago
            electricity is basically fungible (minus a distance factor). So if you're using up the cheap, renewable electricity for mining, guess what you're using for everyone else's day-to-day electricity? Yep, fossil fuels. (https://www.theguardian.com/technology/2022/feb/18/bitcoin-miners-revive-fossil-fuel-plant-co2-emissions-soared https://www.theguardian.com/technology/2022/feb/18/bitcoin-m...) One major exception to this is geothermal electricity in places like iceland where there's abundant green electricity, but you can't transport it to any neighbors. So just using renewable sources for electricity doesn't actually make mining renewable until we're in a society that's 100% renewable.

  Was this left by the person who solved it or the one who stole the prize? See below: https://news.ycombinator.com/item?id=41549946 https://news.ycombinator.com/item?id=41549946

    If the real puzzle solver didn't see this coming, he kinda does deserve it. Bitcoin blocks takes 10-20 minutes to confirm. This leaves enough time for a bot/human to take over. I am pretty sure he could have contacted a miner/pool and arranged a deal with them.
    • ralfd 2y ago
      Can you explain that? So the real puzzle solver could have theoretically triggered the transaction, but lurking bots are stealing the transaction from them?

        > https://news.ycombinator.com/item?id=41555482 https://news.ycombinator.com/item?id=41555482 I'll try to give a brief here about how Bitcoin script works but you'd better read up on the Bitcoin wiki. Essentially, to make a transaction valid, your script needs to pass. 1. <PubKey> + <Signature> -> This is how most transactions are handled. You provide the transaction with a signature. This doesn't expose your private key and lock the receiver. (as the receiver is signed) 2. <Hash> + <Hashed Content> -> To solve for Hash, you need to provide the Hash Content essentially solving the puzzle. Problem is, if you provide the Hashed Content publicly in the Script, anyone can also submit a competing transaction and set himself as the receiver.

      How could a bot/human steal the funds without knowing the private key? Edit: typo
