I googled "zero lock staking" and I'm not finding anything that contradicts what I said. There are systems that allow for delegated staking, where you hold transferable tokens that represent a share in a staking pool - rETH, for example. But there's still locked stake in that case. And this Quora response lists various proof-of-stake systems where you can unstake immediately, including Cardano and Polkadot, but those don't give you rewards while your tokens aren't staked - the token still needs to be locked during the staking itself.
I asked for clarification on what you found "damning" about the transition to proof of stake, I don't see how asking for clarification is "misinformation."
I presented a source for Ethereum's centralization trends. Got any of your own?
That's because there were just a handful of people mining the first blocks and there was no demand, so the price was basically zero.
The protocol is meant to promote decentralization, so I have no idea how a 51% attack would be an example of the protocol functioning properly. A 51% attack is a demonstration that the protocol is controlled by a single entity.
Pants can be what keeps you from freezing to death and going to jail.
This is still dependent on societal consensus. Well, the going-to-jail part, anyway. The protection from cold issue is dependent on the climate and time of year of where you happen to be located. There are many parts of the world where you could comfortably go naked.
there is nothing inherent to the protocol that dictates such massive power use.
Yes there is, massive power use is the entire point of proof-of-work. If Bitcoin blocks could be produced without massive power use then the blockchain's system of validation would fail and 51% attacks would be trivial.
I went Googling for sources, and what I found says the opposite. Ethereum was becoming increasingly centralized under PoW but after the switch to PoS it became significantly more decentralized.
in order to stake to a pool, you need to lock your tokens away, making them impossible to spend for a specified time period.
This is exactly the point of proof-of-stake. You can't prove you've staked some coins if you don't actually stake them. If you've retained control over your tokens then they're not staked. I'm not sure how you think it could work otherwise.
most of the criticisms I have of ETH are more damming of the way they went about the transition between two radically different consensus algorithms than about Proof of Stake itself.
The transition from proof-of-work to proof-of-stake has been on Ethereum's roadmap since the beginning. It was rolled out in stages over the course of years. What was "damning" about the transition?
You think that there are only two possible uses for these things, and if I'm not interested in one of them I must therefore be using it for the other? Pretty weak logic.
If there's no demand for a particular crypto then people mining it can't sell it and go out of business. People mine this stuff because other people will pay them for it.
Indeed. All "value" is ultimately something that is collectively decided upon by society. A chunk of rock could be worthless or worth billions depending on how much people want it.
It's actually more true for proof-of-work mining than it is for proof-of-stake. PoW mining has strong economies of scale, a professional miner with a warehouse full of mining rigs and a special deal with an industrial electricity supplier can churn out hashes more cheaply than a home miner can. Whereas the hardware needed for PoS is negligible so there's nowhere near that disparity between small and large miners.
Also, under Ethereum at least (the largest proof-of-stake chain and the one I'm most familiar with the workings of), stakers don't "dominate" the network. They have no decision-making power over what the consensus rules are. If the users decide to upgrade to a new version and the stakers refuse to go along with that or try to push an upgrade that the users don't want then those stakers lose their stake after the resulting fork.
Most nuclear fission products don't remain radioactive for long periods either, let alone "virtually forever." Bear in mind that the longer-lived a radioisotope is, the less radioactive it is.
Radioactive wastes arising from operation and decommissioning of the JET experimental nuclear fusion reactor, located at Culham, are already factored into the UK radioactive waste inventory. Forecast LLW and ILW packaged volumes are 4,120 m3 and 480 m3, respectively; activated steels and alloy plant and equipment, including the JET vacuum vessel, are a major contributor to the ILW arising.
According to this page a typical 1-gigawatt fission reactor produces 3 m3 of high-level waste per year, 7 m3 of intermediate-level waste, and 90 m^3 of low-level waste per year while operating.
I'm having trouble finding easily comparable numbers for the wastes produced during decommissioning, this page had a lot of detail but was focused more on the area of land that needed to be sealed off rather than the cubic meters of material contained there. It does talk about the mass of some of the turbines being considered as low-level waste being in the range of a few hundred tons, which isn't much.
It's true that spent fission fuel rods are high level waste, but the total volume of that is quite small and it's in a very manageable form. So overall, I'm not really sure there's going to be a big improvement on nuclear waste production with fusion power. It's certainly not going to be a panacea, we're still going to need nuclear waste repositories and still be dealing with processing and sequestering large amounts of materials there.
I have to throw a little water on the "clean" part of the claim, unfortunately. JET does deuterium/tritium fusion, which produces neutron radiation that causes the lining of the reactor to become radioactive. The lining needs to be replaced every once in a while, producing nuclear waste.
Bible promises the End of Days is soon, so we're probably safe on that front. Failing that, just make sure the AIs that wipe us out don't have souls. Or alternately that they have souls that can run efficiently and happily in a relatively small server farm, for efficient use of space.
Heck, upload humans into those servers too and that gives Heaven an enormous capacity.
That's not an "attack."
