Bitcoin uses less energy than clothes dryers, yet you don't see all these disingenuous hypocrites talking about how they can Save The Planet™ by simply hanging up their clothes and waiting a bit longer; they wouldn't dare subject themselves to the indignity of mild inconvenience
(reposting the math here, for ref)
- There are 130M US households
- An avg household uses 12000 KWh / yr (EPA)
- Dryers are 6% of household energy consumption (EPA), which = 720 KWh / yr
- 720 KWh * 130M = 93.6 TWh
- Bitcoin uses 70-120 TWh (estimates vary)
^ that's just the US
Be sure to notice this calculation was only the energy consumption of clothes dryers for US households. Total worldwide clothes dryer energy consumption is ~3-4 times greater than the 93.6 TWh US-only figure above.
If you like this tweet, please see my favorite tweet about the 5 things I would like to do that will make this handwringing class of petty authoritarians more mad than an overheated clothes dryer:
Also consider the standby energy consumed by laptop/phone chargers and other plugged-in devices: this draw is a pure waste that consumes ~250 kWh annually per household, and across all households that amounts to far more energy than Bitcoin uses as an entire network each year.
And what does Bitcoin do for less than the collective energy our devices use *while off*? Bitcoin converts it directly into mathematically hardened armor that compounds every 10 min, yielding a chronological record of events that can decentralize both money and identity systems.

There's growing excitement among devs about writing backend code via 'serverless' provider services. While it's definitely cool to run backend code w/ less management hassle, is that the best 'serverless' approach we can muster?
I think we can do better: a large % of apps could ditch backend code altogether, if only there was a standard/common way to store their app's data with users, automatically persistent their app's data across devices/infra, and CRUD/query it just as they would any other backend.
How would it work? Surprise, surprise: the key is decentralized identity technology --> one key component of decentralized identity tech is something called a personal datastore. It's basically your devices + a set of cloud endpoints working together as a replicated personal mesh
