This article is a bit dated. AFIK the latest in web scraping legality is LinkedIn vs. HiQ, where HiQ was scraping public LinkedIn profiles. LinkedIn issued a C&D under CFAA, but HiQ received an injunction that allowed it to continue scraping. This was supposed to be tried in the Ninth Circuit court over a year ago, but not sure what happened
> Last month, the inevitable happened: Brady Gaulke, a 26-year-old Nashville man, was killed in a collision with an S.U.V. while riding a scooter. His grieving parents have launched a petition to ban the devices in Nashville. “[E]-scooters are unsafe at any speed, and we are calling on Mayor David Briley and the Metro Council to ban them from the streets immediately,” the petition reads, arguing that Mr. Gaulke should be “the last victim of an epidemic that the e-scooter companies and local government both refuse to acknowledge.”
Imagine being gaslighted by the auto industry so hard that you think scooters are the problem here, not the car that actually hit and killed someone.
All of the problems that are discussed in this article are artifacts of a culture and cities designed around cars, period.
This is so badly needed in the Ethereum space. Metamask is a massive drag and a known onboarding blocker -- Hedgehog seems like a huge leap forward. Congrats team!
Hi John -- sounds like you might be interested in 0x Instant, which lets you offer one-click token-to-token swapping on your website or inside your app. https://0x.org/instant
Sounds like you're referring to security tokens, which place a securitized asset's cap table on a public blockchain. 0x works with all tokenized assets, so we're not opinionated about which assets people want to trade -- other companies like Harbor (https://harbor.com/) offer tokenization services. You're right that placing bearer instruments on a public blockchain presents some issues and the jury is still out a bit.
An alternative might be found in protocols like UMA (https://umaproject.org/), Augur (https://www.augur.net/) or MakerDAO (https://makerdao.com/) which allow you create synthetic tokens that trustlessly track the price of a real-world asset by creating financial incentives to rebalance the price of the minted tokens. MakerDAO has already been used to create over $80MM in a synthetic USD token called Dai (https://makerdao.com/dai/) and UMA has created a synthetic S&P500 token, allowing anyone anywhere around the world to get exposure to US Stocks (https://medium.com/uma-project/announcing-us-stock-index-tok...).
First question is about decentralization. What is off-chain relay in this case? Is that a centralized part of the system? Are there centralized parts of the system?
Off-chain relay is how parties find each other facilitate a trade. As a maker, I can create an order off-chain, but I still need to find a relevant taker who is interested in filling the order by sending it to the 0x smart contracts on-chain. Relayers pool together these off-chain orders and serve them up through a website, so that it's easy to find people to trade with. Note that this process is optional -- you can still trade peer-to-peer if I send you the order over email, SMS, etc. While relaying is centralized, relayers are non-custodial, so your funds are never at risk. We also have plans to make some parts of relaying less centralized in the future through 0x Mesh: https://blog.0xproject.com/0x-roadmap-2019-part-3-networked-...
Can this be used to implement more robust margin trading?
As for margin trading, yes, you can trade dY/dX tokens on 0x relayers, or combine 0x orders with any on-chain lending protocol such as Dharma or MakerDAO to get leverage.
What settlement speeds can be expected?
All trades currently settle on-chain, so the Ethereum block time is our bottleneck. Look for some updates on this near future :)
If you want to list the same assets as everyone else with the same interface in the same markets, then yes, it's hard to compete. However, we see a world of tokenized assets coming online that will need unique markets for exchange. Something like Radar Relay (https://radarrelay.com/ for ERC-20 commodities) is totally different from Veil (https://veil.co/ for prediction market shares) is totally different from BoxSwap (https://boxswap.io/ for trading collectibles). Even within ERC-20 commodities exchange, there are many different models of exchange within different markets that are sufficiently differentiated.
We think of 0x more like Stripe: an under-the-hood technology that allows entrepreneurs to move more quickly and easily add exchange to their product. The concept of "tokens" and "exchange" will become very abstract in the near future.
You don't have to trust! 0x Exchanges are non-custodial -- you hold onto your funds and atomically execute trades through the 0x smart contracts, which are open source and audited.
How would it be lousy? The cars can now go anywhere and dynamically route instead of being stuck on rails and the infrastructure costs are orders of magnitude less.
The most worrying part of this article for me is that processed meats that are advertised as "nitrate-free" really just use natural nitrates from celery salt, which aren't much better, if at all.
+1. Ability to upload music on Google Play Music is also keeping me from switching to Spotify. I have a lot of tracks that simply aren't in the Spotify catalog. If they add that, I'd switch tomorrow.
Not really a 'blockchain alternative' -- just a clone of Airbnb that lets you pay in cryptocurrencies. Kind of a shame when there are other actually decentralized home sharing platforms like Beetoken, Origin, etc.
Reddit is a YC company and HN is just a free service provided through YC (not a company), so it doesn't really seem like they have the incentive to do this.
