usehackernews··on Interview with Vitalik Buterin on ETH2, Scaling Plans, NFTs, etc.
Counterfeit or pirated goods accounted $522 Billion or 3.3% of all global trade last year according to the EU Intellectual Property Office (EUIPO).

And Shoes are the most counterfeited product in the world. 2 I don’t have specific shoes figures, but here is an article about a $400 million fake shoe bust customs made 3.

Yes, counterfeiting is a major problem worthwhile of extra transaction costs.

In the art business, confirming the legitimacy of a painting is a $1b per year market.

What happens when you lose your key? Price would drop in value, I imagine. Similar to if you accidentally dirtied your shoes, both requires being careful and aren’t mistake proof. However, I’ll let people smarter than me figure this out.

You can’t give 10 Fake Nikes the address of Nikes original wallet, that’s not how this works. You can’t just assign an NFT any address you want, this is all verified via smart contracts. The point of the block chain is that it’s immutable.

Here’s Nikes patent for this:

The token does not notice, and that’s exactly what we want. As the original buyer, the token is already stored in my wallet when I bought the shoes from Nike.

Whoever stole the item can try to sell it, but given they don’t own the wallet that the token lives in - everyone will know it’s a stolen good. Another benefit of NFT for psychical goods.

There’s a massive forgery issue with physical items - Shoes, Fashion Brands, Art.

The benefit of NFT for psychical goods isn’t so much proving who the current owner is as much as it is proving the historical ownership so the authenticity of an item can be ensured. You don’t need a central government for this. For example, as long as you know Nikes address, I can confirm a shoe I want to buy is truly authentic by verifying that address is the original owner.

You seem to have a good grasp of creating high level models.

I always see people referring to the energy consumption of bitcoin as though it’s strictly additive.

What I’d be interested to know is how it compares relative to energy costs for transacting with and securing fiat currencies.

Second, what people tend to ignore is that innovation doesn’t come in a vacuum - there are second, and third degree improvements triggered from it. In a world where bitcoin is $1million, it means the world has agreed on the benefits, and we will see innovations to address the tradeoffs that come from this. For example, we could see significant investment into renewable energy as a means to support the energy consumption of bitcoin.

Third, and this isn’t directed at you, just a general statement based on arguments I see on HN - cryptocurrency itself does not have high energy consumption. Proof-of-work mining does. There are methods to support cryptocurrency that do not result in high energy consumption (Proof of Stake, DAGs). It’s wrong to generalize energy consumption issues to all cryptocurrencies.

It’s not just your opinion, we are in a technological productivity stagnation and have been for years.

usehackernews··on Bitcoin surpasses $50K as major companies jump into crypto
If you’re not sure what real problem bitcoin is solving then you are living in a bubble.

30% of the world unbanked. Bitcoin provides a way for them to store their money.

usehackernews··on Bitcoin surpasses $50K as major companies jump into crypto
Yes, mining pools are aggregating. None are at 51%. But, the risk is bad actors, not the mining pools. Hypothetically, if a mining pool had 51% hash rate, why in the world would they tank the price of the asset their entire business is based on - They would lose hundreds of millions, if not Billions of value.

Bitcoin is offering the 30%+ of the worlds population that is unbanked an opportunity to do so. Bitcoin is providing those living in a poor economy a route to economic alternatives.
usehackernews··on Tesla buys $1.5B in Bitcoin, may accept it as payment in the future
Your naivety of bitcoin use cases is very stuck in the Silicon Valley perspective. Not everyone has ways to store their money, earn interest on money, and receive loan opportunities.

Bitcoins accessibility to people without banks is an extremely valuable asset to the world. This is at least 30% of the world population.

Bitcoin is 12 years old. It’s very very young. Problems will be addressed as it matures.

Further, every currency has problems. Is USD perfect in your mind and without it’s own unique set of issues?

Proof-of-stake consensus is one answer to this. It’s what the Ethereum network is implementing.
usehackernews··on Janet Yellen suggests 'curtailing' cryptocurrencies such as Bitcoin
I think you’re quite misinformed.

This would take many many many billions, not “many millions” as you said.

The daily trading volume for bitcoin is $64 billion.

Buying “many millions” worth of bitcoin would not achieve what you’re proposing.

usehackernews··on BioNTech CEO applies Covid-19 vaccine's mRNA tech to multiple sclerosis
I state that CRISPR benefits researchers. However, that is still a niche benefit relative to the long term societal benefits we anticipate from CRISPR.
usehackernews··on BioNTech CEO applies Covid-19 vaccine's mRNA tech to multiple sclerosis
CRISPR is a great example of a technology that has not yet made a meaningful economic contribution. Although the technique for editing DNA was discovered in 2012—and a Nobel Prize was awarded to its two discoverers this year—no treatment using CRISPR has been approved outside of clinical trials. So far, its impact has been limited to making researchers more productive—not a bad thing, to be sure, but not close to CRISPR’s full potential. As trials progress, however, I do think some CRISPR treatments will come online in the next few years, especially those targeting genetic disorders that we have very limited means of otherwise treating.

usehackernews··on Ask HN: Who's looking for a co-founder?
Seems you understand the pain point. There have been numerous people who have asked for help learning SQL, and they never see it through. On the other side of the problem, analysts at companies are not there for simple SQL queries, it’s an inefficient use of time as opposed to in-depth analysis.

Email me at DPublicEmail@protonmail.com and I’ll give you my personal contact information.

usehackernews··on Ask HN: Who's looking for a co-founder?
Hi, I’m Dave.

I’m a product manager that is sick of operations & other PMs asking me to write simple SQL queries or create tableau dashboards.

I’m creating a tool that translates human text into simple sql queries to enable data analysis for everyone without needing to learn SQL.

“How many [column name] did we have on [Date]”

This isn’t easy, but if done successfully will be extremely valuable.

In Geekbench5, they benchmark html5, SQLite reads, pdf rendering, text rendering etc. Seems somewhat relevant. They are providing an upper bound on this activity, and that’s good to know.

usehackernews··on Portland approves 10% cap on fees that food delivery apps can charge restaurants
The app is a cool idea, however, I’m curious how you guys plan on managing the standardization across menu items. Replicating a single restaurant menu is an incredibly complicated problem given the amount of customization, but you also need to account for the variability of the same menu across multiple services.
usehackernews··on Portland approves 10% cap on fees that food delivery apps can charge restaurants
This is absolutely not the right move.

This is you self promoting your app.

Restaurants will pay more to market themselves, hire delivery drivers, and manage the logistics.

Local restaurants are hurting because of COVID. They are blaming the delivery services, whose proprietary tech, marketing spend, logistics services are the only reason 90% could maintain any revenue stream.
