1. They only accept euros. So you get to multiply the euro risk times the ethereum risk times their oracle keeping your balance on ethereum risk. 2.

Testing is the right place for millions to be accidentally lost.

The DAO wasn't a test, or at least the people involved in it didn't realize it at the time.

And once again: the "AI middleman" mentioned above had very strong human opinions during "The DAO" debacle.

On the site for RWE's charging points, there's no mention of this.[1] The way RWE actually works is like cell phone plans. Users have to sign up for a 1-year contract. This gets you an ID token which the charging stations recognize when you plug into the charger. Then there's an EUR 0.30/Kwh charge, which is billed periodically. That's the usual way the system is used. The Share and Charge system [3] doesn't use Ethe…

Actually, the Euro Token is a virtual FIAT implemented on Ethereum. I can't reveal much more information on it until the project formally goes live (which is imminent), but I can't tell you it thankfully goes a lot further than what you noted. There's a lot more information coming up because it's my understanding Carsten only intended his tweet a bit as a 'teaser'. I had written this piece back in September when we e…

Who is the debitor in this scenario? In other words, who sends me 1000 EUR via SEPA when I cash in my 1000 virtual Euro tokens?

Seems to me like, when it comes to credit, Chaumian cash makes much more sense, since you depend on a central party anyway. The only weakness of Chaumian cash is the central party, but with redeemable tokens you depend on a central party in the first place, since someone needs to redeem the tokens in question.

> 3. You can't increase security or reduce risk, by layer abstractions on top of other things, in this case, the euro. That is pretty demonstrably false. A lock is a layer of abstraction on top of metal. That can increase security and reduce risk. More directly to your point, a set of investments that are, on their own, extremely risky can be set off against one another (i.e. hedged) in such a way as to make the whol…

Metal door welded shut is more secure than a door closed with a metal lock. Harder to use though. But surely more secure.

Thumbs up for the charging stations. But How does the customer benefit from the blockchain payment again?

Stephan from Slock.it here. Essentially the idea is to recoup the cost of your investment in a charging station by renting it to other electric vehicle drivers that might be passing by. Can't wait to be able to tell you more about it on our blog.

Will you campaign for a hard fork when your contract gets exploited again?

There's a recent podcast about this and blockchain + energy sector in general: https://epicenter.tv/episode/174/ Why blockchain? It enables peer-to-peer buying and selling of electricity (no middle man), which becomes more interesting as the grid itself is becoming more decentralized with solar, etc. Imagine being able to buy and sell electricity directly between you and your neighbors. Lots of questions about how th…

> (no middle man) Just because you cannot go to a miner's office doesn't mean that they aren't a middle man. The illusion of direct payments is simply untrue and you need to trust that there will never be more nodes from people that want to fraud the whole system than there are trustworthy ones. You trust complete strangers with your money that you can never meet and never complain about. Worse, you can't even sue th…

If Ethereum actually worked as an autonomy trustless network (which is what the project claimed to be) then there would be no middle man. But Ethereum is just vaperware and a marketing project

Do they know that all transactions will be public and great resource for competitors? Do they know that blockchain transactions need few confirmations to be trusted and mining takes time?

No they probably didn't do any research before launching this project.

You sound like you are being sarcastic but Ethereum is a vaperware scam so yes they did not research the project.

Note that "Sofortüberweisung" is a service where people do store their private bank account data (!) - when I first saw that I was sure it was a joke, but people are using it.

They even want to store payment tokens (PIN/TAN, however you call it). Yes, you understood it right: they store your secret access tokens to your bank account to make the payment "easy" for you - good luck!

This gives a good impression about technical education in germany, there is still lots of ignorance, not only "on the streets" but also at places where decisions are made.

I don't trust Ethereum. Who's behind it? Are there any backdoors? Why not Bitcoin?

It has the second-biggest market cap at $6 billion, it's been in production for a couple years, it has multiple open source implementations, its inventors and other developers are known to the public, it has much more powerful smart contract capabilities than Bitcoin, and it doesn't have high fees and backlogs.

...and it's a vaperware scam. Their technology just doesn't add up. No way it does what is claims.

Could someone not build something similar, but for WiFi routers instead of charging stations?. I.e. a company selling or renting pre-programmed WiFi routers that sell bandwidth directly to the users. Anyone could buy or rent one and put it inside their private space that is within a public zone (e.g. cafes and restaurants). Thoughts?
