      Believe he would be happy there is no Olympos anymore ;) Of course he deserves our highest respect for all the job made!

    I was thinking the other day that Bitcoin's Lighting Network sounds a lot like a proof of stake system. Was nice seeing Andreas mention that. 🤓

    Probably the best way to generate the electricity to change the blockchain is to drive a Delorean 88 mph at the exact time lightning hits the clock tower.

    What About iota. Apparently they don't need pos or pow. Is this too good to be true?

      @khkgkgkjgkjh6647 6 років тому +4

      Yes. Actually they have the central 'coordinator' until there's enough PoW on the network. Their plan is to have millions and millions of refrigerators and toasters with ASICs and full nodes mining without compensation. :D

    i think it was misleading to use a "rich get richer" argument. rich get richer in all protocols.

  • @freewillftw
    @freewillftw 6 років тому +8

    the rich always get richer and it doesn't matter which protocol you are using, with POW the rich can always build large mining farms and purchase loads of mining machines, and then the economy of scale will drive the mining cost down by a lot, which means more profits, and these profits can then be used to keep on expending the mining operation if they will. in POS the validator is randomly assigned and the validator has to complete the validation process in a very small time window. This means it is very difficult and very costly to attack the system.

      The Real Deal And what happens if someone owns enough mining hardware to attack the Bitcoin network? Same deal. And guess what, the three biggest BTC mining pools control >50% of the network.

    Thank you for your great work!
    Question about power consumption (around 4:30min): If the network runs at 500MW to 1GW then it will have used up between 12 to 24 GWh in 24h - how do you come up with only 1.2GWh?

      Indeed. It was a minor mistake.

    Important issue of the current bitcoin implementation

  • @cryptolete6033
    @cryptolete6033 6 років тому

    but what if there's a 51% attack where they change the current block and they don't start 3 weeks back? Seems like they could do that not too difficult

  • @DefensorVieira

    When the POW rewards can no longer justify the electricity costs what happens to bitcoin? what happens when the miners switch off?

    • @splutbets6889
      @splutbets6889 6 років тому +3

      Read up on the difficulty adjustment property of Bitcoin. rewards/price & electricity costs will always eventually follow each other as a result of it.

    With PoS, who validates the validators?

    Wait but what physically does the processing in a pos blockchain?

    • @MiniRockerz4ever
      @MiniRockerz4ever 7 років тому +1

      you don't need that much processing power to simply record things to blockchain....in proof of work it's artificial math solving that requires 99.5% of the power

    "The rich gets richer"!? That's also the case for pow, more or less(?)

    Vericoin has proof of stake time which attempts to mitigate the rich get richer issue.
