I hope I'm not being lazy, but does POS not just mean the more you have, the more you get? Wouldn't it converge to 1 wallet controlling everything? Or to rephrase the question: where can I find the "POS for dummies" page?

Yep, it literally codefies "rich gets richer" down to the core of the protocol.

Just saw that you need 32 ethereums to be able to stake. That's more than 60k.

Whatever, I'm out.

PoS is not just a more environmentally version of PoW. It is a lot more vulnerable to state level actors. If the state takes over / subverts / influences the limited number of stakeholders, then it is game over. With PoW the state can influence the existing miners, but cannot prevent new independent miners to pop up and counter act.

The exact opposite is true. It's always possible for a state to obtain enough mining hardware - PoW is hopelessly insecure. It also has infinite economies of scale inevitably leading to absolute centralization even absent state attack. Once majority of hashrate is achieved, profits nearly double as minority can be censored. That's the inevitable end state of PoW. PoS is resistant to state attacks because it would req…

PoW can also fork.

It's not just miners, it's also full nodes that validate.

Full nodes can disagree with miners: instant fork.

If say Putin would acquire 51% of mining hash rate people would realize (before he gets there) and would fork.

My comment is not in support or against PoW, I'm just stating the fact that PoW isn't inherently unsafer than PoS.

> If I’m building a marketplace business in 2021, where I want to be “crypto-first” instead of relying on PayPal and Stripe Connect, where do I start? Unless you are building a dark web market, why would you want to? It will be more convenient for the vast majority of users to pay with card or PayPal.

I believe there are some use cases. Think of a government which does not allow currency conversion to more stable currencies in a place where volatility or inflation is very high. In that situation, it might be worth adopting a crypto-first approach, no?

But doesn't crypto have very high volatility?

Good. Very good. This may be a radical take, but I think nations should introduce some unprecedented legislation: ban trade of proof-of-work cryptocurrencies. Don't ban their trade because they make poor financial products, either because of rampant fraud or criminal activity. That's a different argument and requires different approaches. Ban their trade because global society shouldn't accept rampant incentives to l…

So burning electricity on running a cryptocurrency is not right, but burning electricity on running servers for Facebook or user tracking is all right? If that's the case, who's the arbiter of what's "too much" power for a use case? If that's not the case, how do you propose to enforce that all use cases use less electricity, and how do you punish those who use too much?

The key difference is that I'm certain that Facebook makes continuous efforts to use less energy. Maybe not for environmental reasons, but they have an economic incentive to increase efficiency.

Regulating the energy consumption/efficiency is more akin to fuel efficiency standards for cars.

The minimum amount of Ether to be eligible to stake is 32 Coins, so it appears that last year in June, about 120k addresses would've met that criterion[0]. That probably changed by now, I'd assume the number to be higher as more people set up 'mining rigs'. That's at least a larger number than I would've guessed. I wonder how many people/entities are behind those addresses. On a side note, I have mixed feelings about…

>but comes at the great cost that people who aren't already in the game won't be able to acquire Ether without basically paying cash for it. That's a weird dependence on fiat currencies for a 'decentralized ledger'. (And yeah, there might be other means, but none of them are really practical for the average person.)

There's no inherent weird dependency on cash, there's only a dependency on whatever currency people choose to pay each other for work, which currently happens to be cash.

If people started paying each other in Ethereum-based tokens, you could close the loop and cash would not be a dependency.

This just sounds like an excuse to ban something that governments (read: the US) are trying to bring under control.

First it was 'but criminals use it'. Now it's 'think of the environment'. What's the next excuse going to be?

Ethereum proof of work made it so the owners of the coins could be independent from the owners of the mining operations, even if in practice many miners end up keeping most of the block rewards themselves and only reinvesting what they need in new infrastructure and to maintain what they already have. Proof of stake makes it so the miners and holders are now the same (you stake the coins that you have, or you pool th…

Maybe it is spread out now, but won't there be centralized aggregators of eth so some point in the future a handful of POS nodes control a disproportionate amount of power? Is it so hard to imagine that coinbase or some other exchange accumulates enough eth to sway transaction validation? Seriously, please answer if this is wrong!

I do think there will be some centralization at the exchange level. As of April 2021, Kraken had 600,000 ETH staked for ETH2 [1].

It's not in the interest of Kraken or Coinbase to disrupt one of these PoS networks, but there is some barrier to entry for staking ETH2 or other PoS coins on your own, vs staking them on an exchange. In the case of ETH2, if your staking node goes down, you get slashed and lose some ETH. If there isn't slashing (not all PoS coins have that), I don't see what guarantee of network security or uptime there is.

I'd be curious what PoS coin experts think about this part. It seems like PoS / staking can lead to centralization. PoW has energy concerns for sure, but it has so far demonstrated decentralization pretty well.

I'm legitimately curious about this. I'd love for PoS to be feasible and am trying to understand it more.

This is one of those "Freakonomics" type ideas. On the surface this sounds like bitcoin's PoW use will simply stop. It's actually the entire opposite. When governments ban it, they go after sizeable, identifiable organizations running these operations, that is their only choice. These operations are optimized in their energy usage, because it's only in their interest to reduce their consumption relative to the value…

> smaller operations and hobbyists will rush in to fill it. Hash rate gradually climbs back up and instead you have 10x the energy usage because you can no longer run the PoW in a scalable way.

This is false. Miners will spend about the same amount of money they get from block reward to run their operation. Asymptotically, this money is spent to buy electricity. This is the result of competitive pressure from other miners. What you will observe instead is the same amount of electricity burned but with 10x less hash rate.

The elephant in the room is bitcoin literally requires the mass consumption of computation to work - the more the better. And it was designed this way. In comparison, Facebook and industrial processes work to make their processes more efficient and use less resources for their workload. Bitcoin will just gobble up any efficiency to do more mining and end up consuming the same amount of resources.

Bitcoin is an endless energy pit. The same isn't true of things like Facebook.

Why do HN comment threads always end up as Pedantry Pageants where all ye who dare comment must address all the fucking edge cases or be called out by the immediate first child comment about failing to do so. It's SO trite, predictable, wearisome and boring . It always follows the same pattern too. "Where do you draw the line?" "Who decides what's the truth?" Always the same fucking slippery slope fallacy. Every fuck…

> edge cases

That’s the first time I’ve ever seen someone describe Facebook as an “edge case”.

If $900,000,000,000 of market capitalization counts as an edge case, I’d think you must be hard to please at Christmas - those are some really high standards!
