Proof of stake is relatively simple. You agree to stake a minimum amount of tokens (decided on by the network) and you get to run a node and validate transactions. If you attest to a malicious block and other validators call you out on it, you get slashed (i.e. you lose some portion of your stake, if not all of it): https://ethereum.org/en/developers/docs/consensus-mechanisms... One of the problems with it is that it…

Nothing about Proof of Stake is relatively simple lol. Not the incentives, not the threat model, not the trust model, not the impact on the economics, not the implementation, not the scalable byzantine fault tolerate research. There are plenty of people who understand it well, I'm not saying it's outside of reach of a normal human being. But understanding proof of stake is not a 30 minute journey. (nor is understandi…

I think it is relatively simple compared to proof-of-work don't you? And it's not really hard to get at a conceptual level even if the implementation level is far more complex.

I post a deposit that says I'll be honest. If I'm caught being dishonest, I risk losing my whole stake.

And this is not surprising. Cryptocurrency is designed to be anti-efficient. "Proof of work" is just a synonym for "having wasted tons of energy." This is my main beef with these systems. Gaining fundamental value from the act of wasting energy and being the one to accelerate the (local) heat death by the most is not a sensible basis for a 21st century technology.

At that rate and assuming 4tx per second a single Bitcoin transaction consumes 165kWh. A Tesla battery is bit over 50kWh. So let's round that to 3 full charges of Tesla battery. That's 350km/220 miles of range per charge. In total 1050km or 660 miles of driving. So basically if you want to transfer money and the recipient is closer than 660 miles from you it's more efficient to just get a bunch of bills, drive there…

That comparison is flawed. Visa is not money. The purpose of mining is to protect the value of the currency. Protecting the value of the US dollar requires a huge economy with politics and military power.

Wouldn't you eventually need military power to protect your bitcoin mining rig?

Ethereum 2.0 solves this via Proof of Stake. They are rolling it out in 2021 and I think the environmentally concerned will then consider the number two coin because of how energy hungry Bitcoin is. PoS also greatly increases transaction speed.

In the grand scheme, the "tons" (or rather, gigajoules) of energy wasted by the Proof-of-Work are nothing. The Sun radiation that hits Earth every second dwarfs this consumption. Also, one of the definitions of life is "a local decrease in entropy, at the cost of a global, larger, increase in entropy". By this criteria, every living being is a bad thing for the universe, because it accelerates the global heat death e…

>but we humans are insignificant on this scale; there is really nothing that we can do to even accelerate our Sun's death. We're not even Kardashev-1 :)

I am shocked that you are brave enough to write these things in the same comment. The problem with Bitcoin and proof of work is that it's literally capable of consuming our sun and all energy in the universe.

The energy that goes into a Bitcoin transaction doesn't just pay for the one transaction. It also pays for the security of all the value stored in the rest of the system, and that's actually where most of the revenue for mining comes from - inflation, not fees. But also, Bitcoin transactions aren't typically buying coffee from your local store. It's very often international, and Bitcoin transactions offer a finality…

> The energy that goes into a Bitcoin transaction doesn't just pay for the one transaction.

No energy "goes into a Bitcoin transaction". A block with 0 transactions and a block with 100 transactions will both take the same amount of energy to generate.

Indeed, the comment shows how valuable Bitcoin actually really is - it's pretty impressive.

Interesting take. Does the amount of money spent on Herbalife show how valuable it actually really is? What about essential oils or healing crystals? In a tautological way, sure, everything's worth what somebody's willing to pay for it. But the above examples must call into question whether there is a distinction between what something is worth in dollars, and what its merit is.

Good points. To give it a totally different spin, imagine Bitcoin's value is pretty constant actually and what changes is the dollar (its being devalued at a rapid pace at the moment).

There is only a limited supply of Bitcoin, but there will be more and more dollars printed over the next decades (making the dollar even less valuable compare to the constant Bitcoin). So Bitcoin will be interesting to watch - quite exciting for future and to see what's gonna happen.

What about all those Lightning Network transactions on top of Bitcoin?

Lightning removes any of the benefits of Bitcoin by being a traditional trusted payment system.

If you think lightning is a "trusted payment system", you clearly don't understand how it works.
