      this is false. You cant calculate transactions of bitcoin like this. Is completely wrong and you expose yourself as a ridiculous tech site.

      They probably mean "one block". Which is only went on a technicality. BTC's energy usage is a serious climate change issue!! It must be powered by blockchain verified renewables!!

      one block is not one transaction. Bitcoin has use only a tiny amount of energy if you compare this to the energy that use data centers to secure the world digital banking system.

      sorry to tell you this but every centralised banking system out there is more efficient than bitcoin because they have economies of scale whereas bitcoin is the opposite

      They mean one transaction. Do the math. I did and it checks out. 300 kWh *per transaction*. Not per block. Per single transaction in the block. Yes, Bitcoin is *that* ridiculously inefficient.https://twitter.com/marcan42/status/953775357978591232 …

      Bitcoin consumes 4,000,000,000 W of power to process four transactions per second. A single Raspberry Pi with a database can do an order of magnitude more on 5W. Think about that next time you wonder if it's a good design.

      how you calculate txs per block when every txs can include dozen of transactions or when every block has not stable txs? Public your paper and your calculations so everyone to do a proper tech analysis. Now you say just bullshits or worst just a click bait.

      You calculate the maximum number of transactions per block given the blocksize limit. Read the thread. This is not rocket science. You take publicly available estimates of Bitcoin mining power consumption and do some simple math.

      no you cant. And is another proof that you dont know how bitcoin-blockchain works. I dont say that bitcoin not use energy but this calculations are completely false.

      If you want to claim I made a mistake in the calculation, you're going to have to point out the mistake. Just saying "you're wrong" without an explanation just makes *you* look like you have no idea what you're talking about.

      I'm sure I don't know how Bitcoin works; I just happened to read the original Bitcoin paper and build a Cell SPE miner 8 years ago. I also got out when it became clear the community had spiraled out of control and the current system was unsustainable.

          you built a Cell SPE miner and you calculate bitcoin transactions as a sigle input output? lol Your maths are wrong. Do a proper work, calculate again, compare it with how much energy use the Banking sysrtem (ATM, data center etc).
