Whenever someone mentions smart contracts I'm instantly reminded of that Jean Luc Picard quote: "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."

True, but on the other hand if you have options or futures contracts, you expect them to execute as specified. That's the sort of thing mainly running on Ethereum.

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…

Why did you not add "Who can guarantee that? Nobody." to the PoW description as well?

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

Interesting! How are they wrapped? Do ppl trade bitcoin on ethereum without actually using the bitcoin blockchain?

They trade a token, sometimes called a stablecoin, that represent BTC as its underlying value.

Primarily two extremes for how this is done: Centralized, like WBTC (https://coinlist.co/help/what-is-wrapped-bitcoin-wbtc), and decentralized, like tBTC (https://defirate.com/tbtc/)

I remember Satoshi's old posts where he claimed that Bitcoin Core was the only viable full implementation of the Bitcoin protocol since it had too many quirks to be efficiently standardized and reimplemented. I wonder if that's still true.

Could you expand on a scenario where "traditional banking couldn't meet your needs," but crypto was able to?

I don't entirely understand this, but am I gathering that it's holding money for a "bet," similar to paying into a horsetrack and then going back to collect if your horse wins? Or is it an escrow where, during the time the money is held, it "generates profit" (invested elsewhere?) and then pays a return to those who contributed later?

fwiw - I don't have a yearn account, and am consequently unable to view your yearn link.

Let the party begin.

Are we starting with this even here? Is there really no corner of the Internet that's immune to this bullcrap?

I've always wondered if someone could make a browser plugin to filter anything involving cryptocurrency out of web sites like HN, /. or reddit? Having to read about all this every day contributes to unnecessary anxieties and stressors some folks don't need.

Can anyone give a TLDR of what is significant about Ethereum 2.0 for those of us who don't follow this stuff much? As blockchain tech goes, Ethereum always seemed the most interesting.

It's not the first proof of stake blockchain, but it's the first that allows hundreds of thousands of nodes to fully participate, while also having high security and rapid finality. This is only possible because of math that was developed three years ago. https://twitter.com/technocrypto/status/1330150362427387910 In proof of stake, mining equipment and electricity consumption is replaced by the cryptocurrency itself…

So will this be a new currency or will existing ETH switch to it?

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…

What's the current status of eWASM?

Seems like there's discussion of scrapping the whole phase 2 "execution environments" and just allowing heterogenous execution on rollups.
