    DeFi user studies research - Some of my findings!

    Posted: 07 Jun 2019 07:08 PM PDT

    I recently conducted an anonymous DeFi survey. The results are really interesting.

    I'm sharing some of my findings with the community and would appreciate any input!

    ​

    1. A majority of users used MakerDAO, Compound and dYdX in descending order
    2. Most users heard of DeFi apps through Reddit and Twitter.
    3. 47% of users classified themselves as lenders, 33% as borrowers and 33% as both
    4. People chose to trust apps based on the following facts: Trustless(72%), Smart contract audits(63%), Social proof(45%), Aligns with the ethos of crypto(36%)

    ​

    ​

    What attracted you to DeFi?

    This was one of the most interesting questions, given it was free response. Overall, here were some of the facts mentioned:

    • Monetary policy not controlled by a central bank
    • Lowers the barrier to create new products vs. traditional banking system
    • Serves as a release valve for overaggressive government regulations
    • Transparency
    • Can be audited
    • Fairness
    • Eliminates rent seeking middlemen
    • Open 24 hours a day
    • No credit checks
    • I don't have to ask permission from a financial intermediary

    ​

    Overall, this was an insightful survey and I'd love to hear more from the community about what you think. I'd love to spark a productive debate where we debunk DeFi together. Its an amazing time, we're so early in the space and it'd be great to quantitatively understand DeFi.

    how stupid is this idea

    So, I have turned a private key in to this.

    ౫⸕Ψ၄⼺౪ػᙢᙢϡגӞ၄㇋ϡػᙢ

    I have assigned 0-9, a-f with new characters that I have picked that mean something to me. So, I can look at one of those characters, and tell you in a millisecond what it is (an A? B? 7?)

    Not only that, but I have added several numbers that mean something to me only. (no, not birthdays, but like the old phone number to our house from like the 90s etc) And i've inserted those numbers randomly in random places. Not only that, but there are additional characters that are meant to be nothing. They are to be deleted completely during conversion. There is also another thing which i have done to the character set that will alter the way things are. No, not a Caesar cypher, but something I don't wanna disclose. excluding that, since it's an unknown, what are the chances of someone cracking this? should be fairly low right? I mean, I should be able to just print this off and attach it to the fridge and print it on a shirt. no one will be the wiser!

    Why is a decentralized identity impossible?

    Posted: 07 Jun 2019 01:34 AM PDT

    Maybe I misphrased it, but I've read comments recently that suggested that it is impossible to prevent people from using more than one digital identity, in voting for example.

    ​

    I am not so sure. If not complete, there must be an approximation that allows for a sufficiently reliable way to prevent this.

    ​

    I am thinking of a system in which I have a token that contains all possible identity traits in an encrypted form. If I want to show one ore more of them to someone else, I can whitelist him for a certain time. A photo should be included, so basically it's a digital passport (this would be similar to civic or uport).

    ​

    How to make sure I don't create a false (or multiple) identities? I would have to ask my family, friends, business partners etc. to verify me. I show them whatever traits or features I can and they can confirm them, by which I earn reputation points and they maybe get paid by me a little bit, if they want. If the reputation score is sufficient, it can be reasonably assumed that I am who I am. These points could also be earned through purchases (confirming the address and potentially the name and the photo). A seller could require a certain reputation to be able to buy from him.

    ​

    If I misbehave, i.e. if I lied about my identity, they will lose their reputation points as well. That way, you would only verify people that you know well enough to be sure that they are who they claim to be.

    ​

    How does someone get verified who doesn't know anybody? Either it doesn't matter because you only need identity to operate in a social setting anyway. Or they go to specialized firms that offer verification (costing more due to the higher risk), perhaps (if they neither have any documents) through the use of biometric data. Fingerprints could be then stored encrypted on the blockchain in such a way that they cannot be used twice. Or the official authority (what civic proposes, although I have doubts that most countries have reliable authorities, and it's kind of centralized again).

    ​

    What if a few people agree to create their own fake little friend that can vote? GPS, IMEI or other metrics could help with that, perhaps requiring in the first few weeks or in regular intervals to compare the locations of the users who validated. It should not be a virulent problem, because with relatively easy means like GPS it should be possible to set the bar too high for mass fraud.

    ​

    I went over the uport and civic white papers, but uport seems to have no way of verification in place, you could make yourself unlimited identities as it seems (could be wrong). Civic has "validators", central identities like governments or people with 'stamps' with which they attest to the identity. The civic whitepaper also talks about some ecosystem, which I don't see necessary in terms of exchange of value or value proposals or such. I only think of one single token that can be attached or referenced in other regular transactions if needed, so if you order something, you put in your token and the stuff comes automatically to your active home address.

    ​

    I am no Mathematician, but there must be some statistical formula which allows to calculate how many "validators" or anchor points (absolutely certainly verified people) you need in order to reach all participants after the six degrees of separation. I imagine it could be only a handful...

    ​

    Maybe this is an old idea or maybe I've missed the point why it is really impossible, but it has been lingering a while on my mind and I wanted to write it off my chest ;)

    Split Nonce

    Posted: 07 Jun 2019 06:51 AM PDT

    I was told by a coin maker that the way to split work to miners is to take the nonce and split the work from different hashes.

    What does this mean?
