"I don't know how to communicate this, or even if it is possible to do so... but the question of justice has concerned me greatly of late. And so I say to any creature who may be listening: There can be no justice, so long as laws are absolute. Life itself is an exercise in exceptions."
I am incredibly happy about this. It's the first step for a major cryptocurrency towards ledger security that does not damage the environment via mining. I always hated how wasteful and energy-inefficient mining is. Staking reduces energy costs by many, many orders of magnitude. With lightweight clients in development, it is possible to validate chain using Raspberry Pi. I hope (but don't expect) that some time in th…
Eventually Proof of Work WILL kill Bitcoin - but I have to admit this may be decades out in the future. Right now, most of the mining is financed via inflation. But as this comes to an end, eventually, the cost of mining will be borne by anyone making transactions on the network through tx fees. Somebody has to pay the electricity bill on all these ASICs. EDIT: One could try to argue that high transaction costs are n…

Having worked with Ethereum, especially the low level bytecode, one of the changes I'm most excited for that I don't see mentioned a lot is the addition of eWASM support for nodes. There's many problems with the two dominant smart contract languages Solidity and Vyper, for instance bloated codegen that had to be patched otherwise complex contracts size could not be deployed[0], or more theoretical concerns such as so…

Multiple aspects. PoS offers much, much stronger security than PoW while being about 4000x cheaper to run and sustainably decentralized. Sharding (along with rollups) allows for a truly global scale platform - over 100k TPS, potentially 1M, while still running on normal computers in people's homes. PoS is a requirement for sharding, as dividing security under PoW would make each shard too easy to attack. Last but not…
> PoS offers much, much stronger security than PoW Uh, why do you say that? The security of PoS in fact ought to be much LOWER than the security of PoW: The goal of requiring proof of work is that you cannot just send multiple versions of the same transaction into different areas of the network to double-spend your money - because you need to commit work for producing a block, and due to consuming energy you can't fa…

The world needs a form of money that is not under the control of any one sovereign power or group of sovereigns. Understanding this may necessitate reading some books, but in short, sovereigns have historically proven to be untrustworthy, so a trust-free form of money is a powerful notion.
Of all the world ills I can think of, none are caused by money as means of exchange or by trust systems more broadly. Crypto isn’t going to do anything for global warming or for rampant inequality caused by the unstoppable compounding growth of big capital (in fact it may do the opposite). The premise that trust systems have failed humanity is flawed. I am willing to be persuaded otherwise but I doubt this will come…

Last but not least, there's no way to delete PoW attacker's gpus, but hostile stake is always going to be slashed. Asic pow chain can be forked - once - to a gpu pow, but that's it, and after that there's no recourse to sustained attacks. This property virtually guarantees that no attack against PoS with slashing is ever going to happen.
I don't understand this. I don't understand any of it. I don't understand cryptocurrencies. I don't understand what problems they really solve. > "Ethereum is open access to digital money and data-friendly services for everyone – no matter your background or location. It's a community-built technology behind the cryptocurrency ether (ETH) and thousands of applications you can use today." I can do all these things alr…
It makes me sad, because I expected a comment like this to be the highest on HN. In the case of Ethereum, digital scarcity secured by a blockchain enables a turing complete state machine that the world can use. In the most basic terms, this will remove clearing houses for transactions of assets. In the long term this will lead to novel types of assets, and make ownership extremely liquid. Imagine using your phone to…
At this point it seems like you've just recreated being a shareholder in a REIT except without all the legal protections.

My issue with these kind of questions is that they're hardly ever done in good faith, and they show over and over again whenever crypto is brought up on HN. Crypto has its good uses, and I've relied on it for my livelihood before (and even wished it wasn't just used as a speculation vehicle) when traditional banking couldn't meet my needs, so it's a very Americentric/Eurocentric thing to assume it's only ever good to…

I think the most interesting development is the increasing amount of Bitcoin being wrapped in Ethereum, somewhat validating the store of value idea, I could see it giving Bitcoin some legs But... is it like sports memorabilia at that point, the value is all perception rather than utility and could one day just.. collapse

There is no way Bitcoin will switch to PoS. The very core of Bitcoin is PoW.
