Each Bitcoin transaction uses 4,200 gallons of water — enough to fill a swimming pool — and could potentially cause freshwater shortages

  • This seems as unlikely to be true, as it does sensationalist. Hate on Bitcoin all ya like, but don’t make off the cuff “calculations” and report it as news.

    • It's not accurate but it's not completely made up either.

      There is a calculable power cost to each transaction. The work isn't just happening on one computer and God knows how many ledgers are out there right? To be able to pay somebody some fractional amount of Bitcoin to buy a pizza, The cost to have generated the Bitcoin the cost to check the transaction the cost to update the transaction and all the different places. We don't see the usage as a problem because it's tons and tons and tons of people paying for it.

      But their calculating the water usage as evaporation for the power plants and evaporation from hydroelectric. Like the freshwater isn't returning to the system in large.

      I wonder how much water was lost to make the pizza?

  • Doesn't the lightning network which is millions of times faster than btc alone solve this?

    • That'd be the same Lightning Network with NP-hard issues with routing and a whole host of problems right down to the fundamentals, right? (1, 2, 3, 4, 5, 6

      And even beyond that, having to stack another layer on there is a technical non-starter to begin with. For one thing, adoption of the Lightning Network is fundamentally bottlenecked by Bitcoin itself - if the entire Bitcoin network was dedicated entirely to onboarding people onto the Lightning Network, it'd take 28 months to onboard all of the people in the US alone, let alone the rest of the world's population.

      There's a saying by Antoine de Saint-Éxupery that's rather relevant here: « Il semble que la perfection soit atteinte non quand il n'y a plus rien à ajouter, mais quand il n'y a plus rien à retrancher. » Roughly paraphrased, it means, "It appears that perfection is attained not when there is nothing left to add, but nothing left to take away." Trying to stack extra layers on top of a precarious base goes against any sound engineering principles. In this circumstance, Bitcoin would be the thing to take away - it offers nothing and is in fact detrimental to an efficient system of exchange.
