  • Can you do a transfer without mining a block?

    No, it needs to be included in any freshly mined block.

    Can you include an unlimited amount of transactions in a block to minimize the wasted energy?

    No, it’s hardcoded to around 1 mb and since the average is 300 bytes, that translates to ~3000

    Can you mine a Bitcoin without wasting an immense amount of energy?

    No.

    So, by math, you take that immense amount of energy and divide by ~3000 transactions.

    You can’t just take in consideration the 3 watts used by your computer in the 300 milliseconds used to submit the transfer, need to consider the whole network

    I would be happy to learn if it’s possible to transfer them without including the transaction in a block, that would be groundbreaking and then the electricity used would be 10000x less



  • please explain how to transfer bitcoin without mining a block, since the transactions are contained there.

    You need to take the energy required to mine a block and validate it (a lot, could power a small town), then divide for the few transactions that could be included in just 1 mb.

    They impose a size limit on the transactions that can be included, so even if tomorrow the transactions increase 10x, each block could contain the same limited number. Of course, if you only count the electricity used by your machine to send the transaction, it’s just a few milliwatts. The problem is all the garbage calculations that need to be done to actually validate it.
















  • Generally good at supporting phones but not at supporting computers, a 5-6 years lifetime is unacceptable from an environmental point of view.

    I experienced it last week when I turned on an old Mac with MacOS 10.7. It can’t run anything. Everything that you download doesn’t run anymore, Firefox and chrome are limited to some ancient version like 40 that breaks every modern website and due to some expired SSL root certificate you can’t access any website that’s using let’s encrypt which is a big chunk.

    And it’s like this not from recently but at least 5 years, so it was put in a corner and never turned on anymore until last week

    It can theoretically be updated to some newer version but the updater to 10.8 has been delisted from the store so you have to alternatively source that.

    For comparison, a PC that was purchased the year prior to that Mac is running the latest version of windows 10 without any issue (except slowness due to the 1st gen core architecture)
