    Help me understand why someone would enter a CDP to create DAI

    Posted: 09 Dec 2018 05:55 AM PST

    I'm sure I have a fundamental misunderstanding, so I'm hoping someone will help clear it up.

    As I understand it: DAI is created by someone locking up 150% of ether required to pay back a collateralized debt obligation.

    So they lock up $150 of ether and get $100 of dai(or something else?) which they can then sell.

    The price of dai remains stable because it's backed by fully collateralized loans so if it goes above $1 people will just create (sell?) more dai by locking up 150% of ether, and if it drops below, people will buy to payback their loans.

    Here's where I get confused based on my understanding:

    Why would anyone lock up their ether to create a CDP and get DAI?

    It seems to me the interest payments go the wrong way. In exchange for locking up your ether you should get interest more like a savings account?

    It doesn't make sense to pay interest for the "leverage" to me, because you're taking out 66% of whatever you put in which is deleveraging.

    In traditional banking system you pay interest for additional assets which makes sense. You are giving risk (that you won't be able to pay back the loan), and so you pay someone else for taking that risk.

    In the case of CDPs (as I understand them) you're basically taking all the risk and paying to do it.

    So I believe I understand the theory behind how dai will stay stable, what I don't understand is why anyone would enter a CDP to create the dai in the first place.

    Edit I may have cleared up my misunderstanding by thinking of it in terms of real estate. You own a $120 house which you owe the bank $100 backed by that house. Just like you own the $150 ether which you'd owe the bank $100 worth. Just more risky.

    So my next question is:

    Realistically how many people/ether will be leveraged up in this way? My gut says dai just won't have the capacity to be a broadly used stable coin.

    Ether prices are less stable than real estate. At least in these early stages.

    What’s the difference between WASM and eWASM?

    Posted: 09 Dec 2018 12:50 PM PST

    I hear that eWASM will be a slightly restricted subset of WASM. But, I haven't found any resources that explain their technical differences, aside from the runtime.

    Example of a real world smart contract? I read many but none would really work

    Posted: 09 Dec 2018 09:20 AM PST

    I was reading https://blockgeeks.com/guides/smart-contracts/ and they have plenty of examples but imo they won't work in real life.

    Suppose you rent an apartment from me. You can do this through the blockchain by paying in cryptocurrency. You get a receipt which is held in our virtual contract; I give you the digital entry key which comes to you by a specified date. If the key doesn't come on time, the blockchain releases a refund. If I send the key before the rental date, the function holds it releasing both the fee and key to you and me respectively when the date arrives. The system works on the If-Then premise and is witnessed by hundreds of people, so you can expect a faultless delivery. If I give you the key, I'm sure to be paid. If you send a certain amount in bitcoins, you receive the key. The document is automatically canceled after the time, and the code cannot be interfered by either of us without the other knowing since all participants are simultaneously alerted.

    Let's say I send you the wrong code and the for doesn't open, what happens? I just lost my money because the smart contract thinks I received the code and I used the apartment. Personally I'd never do this contract if I'd be the renter.

    Some examples are not really clear or are too abstract.

    "UPS can execute contracts that say, 'If I receive cash on delivery at this location in a developing, emerging market, then this other [product], many, many links up the supply chain, will trigger a supplier creating a new item since the existing item was just delivered in that developing market.'" All too often, supply chains are hampered by paper-based systems, where forms have to pass through numerous channels for approval, which increases exposure to loss and fraud. The blockchain nullifies this by providing a secure, accessible digital version to all parties on the chain and automates tasks and payment.

    I bet that when you deliver something you can track that you delivered that product. That can trigger a request to the manufacturer to build a new product. Why we need smart contacts and Blockchain? I can't figure out where it helps against a simple database and some script.

    I don't even mention that the way it works in real life has nothing to do with this. You probably build more products based on past performance and current stock. Not on delivery... Most likely will be triggered on sale.

    Let's move to the next one.

    Another few examples i can't understand or too abstract.

    So my question is, can you provide a real world example of a smart contract?

    I have a feeling it's very very limited... For now. What do you think?

    How do I lock up money in a smart contract for a christmas grab!

    Posted: 09 Dec 2018 01:34 PM PST

    Hey fam, I have to get a christmas grab for a yankee swap. I wanted to continue my streak of being the annoying family crypto bull, by buying a small amount of ether and a grab gift. Can anyone give a quick explanation or link to show me how to use a smart contract to lock up a wallet for 2 years or so? because the real gift I am giving is the "hodl" and i don't want to convince my cousins to not spend free money for 2 years. thanks lmao

    When will Serenity (a.k.a. Ethereum 2.0) launch?

    Posted: 09 Dec 2018 05:48 PM PST

    Is there any rough guidance from Vitalik, the Ethereum Foundation, or other developers on when Serenity might launch? Is 2019 realistic, or will it be multiple years? Are there any timelines for milestones along the way?

    How is the beacon chain going to RNG?

    Posted: 09 Dec 2018 04:13 PM PST

    Is the spec it says it's going to use a VFD, which to my knowledge can be executed faster with more powerful hardware. I think this is going to be one of the hardest part with implementation of POS, it's possible to use block hashes on the POW chain but even those are susceptible to hash manipulation, even more so now with the cost of eth and less hashing power.

    Decentralized Finance News and Dapps?

    Posted: 09 Dec 2018 03:13 PM PST

    The idea of decentralized finance (de-fi) is really exciting. I would love to stay as up to date as possible on all the developments that are happening in the de-fi space, but I am having a hard time finding medias/groups/news orgs that cover the de-fi industry specifically.

    What groups or organizations are there that specialize in, or focus on, de-fi news?

    Also, Beyond Maker Dao and Compound, what are some other up and running de-fi dapps that are worth checking out?

    👍🏽🎅🏽
