Re:Show HN: The Ultranet – A Truly Decentralized Private Marketplace
on Monday February 10, 2020 @11:06AM (#22290286)
First, just to clarify, because listings are stored in a "block pool," a new data
structure that this system introduces, they disappear after they're no longer
useful (specifically when the merchant who posted them is no longer a top
merchant in terms of score or when merchants delete listings). This is in
contrast to a blockchain, which generally is required to store all data forever
even when it's no longer useful. This is covered in section 6.5 in the paper.
But of course, even with the ability to "forget" listings, you won't hit Amazon scale if every node is storing every listing. There are multiple ways to think about this.
The first is the argument that the Ultranet is still useful and highly-differentiated as the only private censorship-resistant marketplace, even at its initial scale (not unlike how Bitcoin provides a lot of value without scaling to Visa or Mastercard levels). Section 5.6.1 from the paper discusses this.
The second is the classic "we can always scale later" argument. For this, section 3.4 discusses how the Ultranet has much more incentive to scale than cryptocurrencies like Bitcoin and Ethereum due to the fact that it implements hyper-deflation, and section 7.3 discusses a more in-depth plan to scale the system by ~50x or more using the same mechanism that powers the built-in decentralized exchange.

Now imagine if all the countries would not produce unnecessary waste... We have some serious problems when it comes to consumerism and excessive waste. We need to become more self aware about the environment we live in and contribute more, in a positive way, in our communities.

Every time I get lonely I want to adopt a puppy. Then I struggle with the thought of my incapability to make him happy because of my lifestyle (I don't have my own house and move frequently)... Of course I feel even more miserable than before when my sadness was caused by my loneliness.
This happens at least once a month.

Fuel-efficiency and increased range are enticing airlines to opt for smaller planes on longer routes as they seek to control their operating costs.

Re:Applying deep learning to Airbnb search

but booking with Airbnb was great at one point and it degraded greatly IMHO.
I couldn't agree more. I'm traveling pretty often but in the last year I have to say that I ended up hating Airbnb for their high fees, lack of customer support,and the plenty flaws in their system. Lately, I'm using booking.com just because are more professional and they even offer discounts after various bookings. A big minus with booking would be the small hotel rooms with no kitchen (not so cozy).
