Eth2 dev here, maintainer of https://github.com/prysmaticlabs/prysm , one of the implementations currently running the blockchain written in Go. This has been a monumental effort. There are 3 other implementations in mainnet, and consensus is running perfectly. Few other protocols in blockchain have more than one dominant implementation. The beauty of eth2 comes from its efficiency in signature aggregation: https://t…

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.

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 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…

> 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…

Security deposits of attackers in ethereum are slashed, up to 100%, in case of an attack. The value at stake can potentially grow into hundreds of billions, much more than any PoW chain can hope to accumulate in mining revenues in its entire existence. 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,…

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…

For me at least, "Imagine the possibilities!" is not an answer to the question, "What's it good for?" Indeed, my experience is that it's almost an anti-answer. For example, in the mid-aughts I was talking with the CEO of a well-funded "semantic web" company about joining. I liked the people and the tech was cool, but I just couldn't figure out how it would turn a profit. His answer was similar to yours, a "what could…
