    As more and more people are restricted from their right to trade in by the likes of Robinhood and other platforms, I am here to propose my solution. A Decentralized Stock Exchange Discussion

    Posted: 28 Jan 2021 03:20 PM PST

    A year ago I start production of creating a decentralized stock exchange that would allow people to trade without the median party interfering. I got pretty far in the project but I had to table it to focus on other businesses. But Since now is a better time than any to introduce this, I will offer both the video explaining how it works and the foundational code of this project to hopefully build something for the people. I hope that this can be a community collaboration with this fellow community of developers to weigh in on how they wish this project to progress! If this gets a lot of support we can turn it into a foundation where the people contribute.

    The Code: https://github.com/tycooperaow/stock-dex

    The Explainer Video: https://www.youtube.com/watch?v=TcR-eGkItE0

    My Documented Journey before I tabled it: https://twitter.com/tycooperaow/status/1210734095447117824

    If anyone would like to help to contribute to this project I am all for it!

    GME Trading - Best example of why we need Decentralized Exchanges (DEXs)

    Posted: 28 Jan 2021 01:45 AM PST

    If during this whole process of /r/WallStreetBets attacking institutional short-selling assholes is not the best case for for decentralized exchanges (DEX's) idk what is. The market making platforms literally halt trading on reddit stocks like GME, AMC, and BB multiple times during the trading session making it so you cannot trade the way you want. This usually happens when the short sellers trigger a huge sell off, and you bet your ass they have a mainline that's directly plugged into the NYSE that is going to let them get out of their short positions faster than you can put your buy positions through so that they can mitigate their losses. Now we also have all these different banking platforms putting restrictions on your ability to buy and sell these stocks, the highest volume stocks ever, while having multiple platforms also crash or become unusable without them having to take any responsibility whatsoever (even though they seem to love taking those transaction fees). Nothing about this whole thing is transparent. DEX's are coming, and while in their current form they are not there yet they will be especially when we add layer 2 solutions or get into phase 2. I can't fucking wait. Ethereum is currently the best poised to take advantage of all of that and together we will have a different way of trading

    Edit: even worst than we thought. Robinhood + all citadel supplied brokers can only sell, not buy. Blatant market manipulation

    PSA: 1INCH Staking pools are vulnerable to a bug that could result in total loss of staked LP funds

    Posted: 28 Jan 2021 11:02 AM PST

    The bug, which is present in 1INCH staking contracts, is described here,

    https://sips.synthetix.io/sips/sip-77

    This is the code that 1inch FarmingReward is using:

    function notifyRewardAmount(uint256 reward) external onlyRewardDistribution updateReward(address(0)) { if (block.timestamp >= periodFinish) { rewardRate = reward.div(DURATION); } else { uint256 remaining = periodFinish.sub(block.timestamp); uint256 leftover = remaining.mul(rewardRate); rewardRate = reward.add(leftover).div(DURATION); } lastUpdateTime = block.timestamp; periodFinish = block.timestamp.add(DURATION); emit RewardAdded(reward); }

    This is the same code from Harvest:

    function notifyRewardAmount(uint256 reward) external onlyRewardDistribution updateReward(address(0)) { // overflow fix according to https://sips.synthetix.io/sips/sip-77 require(reward < uint(-1) / 1e18, "the notified reward cannot invoke multiplication overflow"); if (block.timestamp >= periodFinish) { rewardRate = reward.div(duration); } else { uint256 remaining = periodFinish.sub(block.timestamp); uint256 leftover = remaining.mul(rewardRate); rewardRate = reward.add(leftover).div(duration); } lastUpdateTime = block.timestamp; periodFinish = block.timestamp.add(duration); emit RewardAdded(reward); }

    Notice that The Harvest contract fixed the bug with the "// overflow fix" line.

    For some reason 1INCH did not fix this bug before deploying the contract.

    The admin who can call this function (called "rewardDistribution") is a multisig, but the owner who can change the admin to any address is a regular Ethereum address!!!

    If the private key of that address is compromised, the attacker can set the reward such that there is an overflow, making it impossible to withdraw the funds underlying the LP tokens, and effectively burning all the ETH, or other assets staked, forever!

    ​

    Please fix your contract 1INCH, so that in the case of a security loss of your private keys, the attacker can't destroy the funds of your LPs! You have over $1Billion at risk now.

    Stock market on Ethereum

    Posted: 28 Jan 2021 12:05 PM PST

    Hey guys,

    Im sure you are aware of what happend in the stock market the last few days and the restrictions today. My question: would it be possible to bild the stockmarket on eth using smart contracts? So it could actually be a free and open market?

    Could traditional stocks be migrated to Eth blockchain with a DeFi dapp?

    Posted: 28 Jan 2021 12:16 PM PST

    Sorry if there already is a dapp for this that I don't know about. I just thought if it were possible AND if companies were convinced enough to use it, it could be the next big thing.

    Take Tesla for example, where is the information storing who owns what stock? With the brokers I imagine or with some certificate. This could be on chain data...

    Denex | The Decentralized NFT Exchange

    Posted: 28 Jan 2021 09:43 AM PST

    Hi Everyone,

    Today we are announcing the start of our project: Denex, an open-source and decentralized NFT exchange with hyper-customizable NFT listing options.

    Non-Fungible Tokens (NFTs) are unique and semi unique items on the blockchain. Fungibility refers to the ability for an item to be exchanged interchangeably and indistinguishably with another of the exact same item. For example, if I give you a dollar bill and you give me another dollar bill, we each still each have a dollar. Dollars are fungible. Now instead imagine I gave you a house and you gave me back another house. Down to the smallest details there will be a difference between any two houses in the world, and it is not an item that is interchangeable with another of the same item.

    NFTs currently have the highest potential out of any technology in blockchain. There is work being done to tokenize real estate, and you can buy insurance contracts stored as NFTs. Additionally, the cryptoart world is thriving, passing $8 million USD in sales December alone, and even Christie's auction house sold NFT art in September. Looking at the future potential of the NFT space, it encompasses the entire real estate, automotive, art, collectable, insurance, and gaming industries, and effectively any other unique item you can think of.

    After many conversations with NFT creators and collectors, we have set out to fix some systemic issues with the NFT space. Namely, the trend of centralizing technology to create switching barriers within platforms.

    From a technical perspective, the value of NFTs stems from three things: provable rarity through the blockchain, secure and immutable ownership of tokens, and censorship free participation in the ecosystem. At the moment, only one of those things is true for NFTs. NFTs are provably rare by and through the blockchain, but even that is being threatened by "gasless minting" which essentially lets you sell something as an NFT before it has actually been created. In the case of secure and immutable ownership, the metadata which make up the contents of the NFTs are almost exclusively stored on private servers, making them easily alterable, and if the company storing them goes away, so does the contents of the NFT. Finally, censorship free participation in NFTs is constantly under threat from the centralization of NFT metadata, and the limitation of open and customizable transaction options. Even on a decentralized network, dictating the way people exchange items opens the door to censorship of the exchange of those items, and if the decision making those restrictions is centralized, it becomes centralized and censorable from the top down.

    We have set out to fix these problems, and ensure that the NFT ecosystem reaches its full potential. To do this, we are building some key functionality into our NFT marketplace, focused on open access to contracts and customizable listings. These features include:

    Global ERC-20 compatibility Muti-Token Listings Non-Locked NFT Listings Buy Now and English Auction Variable Timeframes Decentralized Governance

    We will also be launching our token, DNX, in a pre-sale in the near future. The DNX token will have some key functionality within our marketplace and ecosystem as a whole. That functionality includes:

    Liquidity Mining Governance Discounted Transaction Fees Staking for Various Platform Functionalities Trade Mining

    Best, The Denex Team

    WeeWallet Ethereum scam?

    Posted: 28 Jan 2021 10:40 AM PST

    So I've just discovered that my mum bought into this sketchy looking wallet which supposedly lets you buy Ethereum. It's called WeeWallet and it's kinda scaring me because we've invested about $500 for 100,000 'tokens' which can apparently be traded for ETH.

    She was told by a friend that has invested quite a bit and she's been convinced that this app lets you invest into ETH and that your money will be returned? I'm kinda confused because when I look it up there's no results but when I look up WeeCoin it comes up as a scam.

    It's kinda scaring me because it sounds just like a Pyramid Scheme as she's been told to refer her friends and then to refer their friends... So could you guys advice me on what to do because the company is apparently saying that the tokens are not worth anything right now because of Covid

    Thanks 👍🏾

    Stake with Lido?

    Posted: 28 Jan 2021 12:29 PM PST

    I don't know much about staking except that it's a way to loan for lack of a better term your crypto and make interest off it if I'm not mistaken. I have Trust Wallet and this Lido thing comes up under DeFi. You basically deposit Ethereum in multiples of 32 and earn some kind of token in exchange, which you earn interest off for everyday you hold in your wallet. When ethereum 2.0 phase 2 comes online you can redeem back.

    What's the point of all this?

    Atomic swaps with centralized services

    Posted: 28 Jan 2021 12:11 PM PST

    Let's say you have a centralized service S, like a bank, which has the following functionalities:

    1 - You can create a charge with a given id, value and receiving address.

    2 - You can pay a given charge and receive a signed proof by S that you did it.

    Then it would be possible to create a escrow smart contract to atomically swap between Ethereum and this service, as following:

    1 - You send your Ether to the contract and simultaneously create a charge in S with a given price. The ether is now locked in the contract as a sell order.

    2 - Some other unknown party locks the order, pays your charge using S and publishes the signed transaction id, along with a receiving Ethereum address.

    3 - The contract verifies the signature and, if valid, releases the locked ether to the received address informed in (2).

    Is there any previous work done in this direction or obvious flaws in this setup? I ask because I think this would be an incredible bridge from traditional financial services to Ethereum, and would allow for a decentralized, peer-to-peer market to be established, without KYC constraints. Not only that, if the market was liquid enough this would also allow for unidirectional payments from Ethereum to S and vice-versa by routing the transaction through the market.

    In fact, Brazil's central bank has just released a system that works a lot like the one described above, and, if feasible, I would be interested in implementing such market, so I'm interested about previous similar efforts.

    Thanks for any replies!
