    A question on Dapps and interaction with smart contracts

    Posted: 08 Sep 2020 02:20 AM PDT

    I'm trying to build a Dapp, but I have a bit of confusion on how I should interact with it. Should the queries go through a RestAPI or should the app be calling the smart contract directly?

    If it's the latter I feel that the smart contract would add alot of extra code (to sanitize queries), but if it goes through a RestAPI wouldn't that be "depending on a 3rd party" which is what smart contracts developed to avoid in the first place?

    Random number generator using consensus-by-bet and one-person-one-vote

    Posted: 08 Sep 2020 07:04 PM PDT

    Inspired by Vlad Zamfir's Casper, assume you have a population registered so that one-person-one-vote is possible. Then, introduce a number of alternative random numbers, this could potentially be the address of every single person. Then, let those people converge on one of those numbers, using a consensus-by-bet game. They simply all just vote for any of the alternative (in case address of each person is used, any of the people), and as a "herd" select a single number with majority. Now conveniently, my invention Pseudonym Pairs provides the one-person-one-vote for this, but, it needs a secure RNG to be safe, so, I was thinking maybe "randomization-by-bet" could provide that.

    Question: 500 DAI missing?

    Posted: 08 Sep 2020 06:30 AM PDT

    Hi everyone!

    I have a question.. recently my MakerDAO vault got liquidated because of the price drop (backstory: https://www.reddit.com/r/MakerDAO/comments/in6vkj/help_eth_gone_after_liquidation/?utm_source=share&utm_medium=web2x&context=3)

    Just before liquidation occurred I tried to pay back part of the DAI debt (~ 500 DAI). However, the transaction took too long to confirm and my vault was liquidated in the meantime.

    So, now I'm wondering what happened to the 500 DAI I paid back? They were not taken into account in liquidation and don't show up in my vault either...

    Vault: https://defiexplore.com/cdp/9471

    DAI transaction: https://etherscan.io/tx/0x1689bbcc72d28fbcb7ce2bbac3c2d7346bba5a25bad3359a4386441571684707

    Appreciate your help! Thanks!

    Smart contracts for real estate, what's the added value?

    Posted: 08 Sep 2020 09:18 AM PDT

    I just got into the world of cryptocurrencies and now I am all way into smart contracts.

    I understand the basics of smart contracts and the need for oracles when in need to grasp data from the real world.

    ​

    I started wondering what would a good implementation of smart contracts for real-estate be.

    I am not talking about big investment companies that want to tokenize properties so to attract small investors that can invest in the real estate market easier faster and with smaller amounts.

    I am talking about normal people that want to sell their house to other normal people and get (partially) paid in cryptocurrencies.

    ​

    The problems I see here are

    1. guaranteeing that the contract releases the money only when there is full proof that the property has changed owner according to the contract itself,

    2. privacy: you don't want share in any way names, social security numbers, property registry numbers by embedding them into the contracts code.

    ​

    To fulfil 1. the contract definitely needs an oracle that interfaces with the real world and with some public institutions to get official documents that states the current owner of a property.

    To fulfil 2 you need to secure the oracle, and be sure that it is not giving away any sort of information that can be tracked down to real properties, or that can connect a crypto wallet address to some name/surname/social security number, ecc...

    ​

    So basically the oracle would be a service that

    1. stores information about buyers and sellers (name, ssn, ecc...)

    2. stores information about properties (registry number)

    3. provides APIs to the blockchain and smart contracts to enquiry for the current owner of properties, not giving away names but just answering yes/no to a query containing a unique ID that refers to a specific contract.

    ​

    Besides the fact that there many more complications and obstacles, like for example the hurdle of querying public databases for properties ownership, I don't see the system unfeasible from the technical perspective. Although such a system would still imply lot of interaction between buyers and sellers. As far as I know in many countries(in the UK, Spain and Italy to name a few) you need to sign a contract in front of a solicitor/notary, who will be in charge of communicating the transfer of ownership to the public institution (HM land registry, registro de las propriedades, registro catastale).

    ​

    So my question is: from the perspective of buyers or sellers what would the advantage be of having their properties bought/sold in such a system relying on smart contracts? They can get away with paying less taxes maybe?

    They can pay using their criptomoney without going through all the steps: getting criptos out of the buyers' wallets to an exchange, converted into real money, to buyers bank account, to sellers bank account, to an exchange and finally to sellers' wallets?

    And from smart contracts perspective, is it worth the effort/cost to implement this system with smart contracts? What is the point of using blockchain if, at the end of the day, all the heavy-lifting is done by the oracle?

    Beginner transfer question.

    Posted: 08 Sep 2020 10:41 AM PDT

    I have such a noob question. I bought for first time some ETH yesterday using coinbase and coin base wallet. I went to transfer the eth into my wallet and said I was only allowed to transfer a portion until my purchase is complete and taken out of my bank (I had about 15$ of token I got for free through coinbase that they said I could transfer up to that amount right away). So I made the transfer for the 15$ but it hasn't showed up in my wallet yet and it's been about 12 hours. Does this happen immediately or does it take a few days?
