Impact Track Submissions

SecureNote

Abstract: A BlockChain Based Textual Content Sharing Application. The Textual content sharing system serves as a major backbone for resolving problems and providing security. Unfortunately, there are some issues with the existing system which can be solved using blockchain technology. In India, most complaints of people are not solved and even if the complaint gets registered, most of the higher officials are unaware of the complaints as most of them are being manipulated in between. This kind of problem can be solved using a decentralized platform for people to register their queries, which all the officials in that particular zone can access and take action immediately without means of altering the message.

Working Model: When a user enters a complaint, it gets registered into one of the blocks in our blockchain system in a systematic manner. Once all the Blocks are mined, a list of complaints are made visible to everyone over the network. As the content provided by the user is stored in individual block which is then attached to the blockchain networks makes it impossible for anyone to alter the content.

StakedTrials — ReciproKitty

Abstract: Reciprocity to enable Decentralized Freemiums Dapps. We use the Measured Transfer Protocol that uses the concept of reciprocity as a means to reduce barriers of entries for new users, to make available surplus tokens, and overall create a means to stabilize fluctuating values. We leverage the power of the blockchain to define a stable value measurement and systematically assure reciprocity in order to create a universal sharing economy. In our Demo, we use a proxy delegate architecture to extend and interact with Dapps that are enlisted in our StakedTrials — Universal Sharing Economy. This demonstrates a way for users to use the dapp, claim tokens and continue to grow your user community through a freemium model.

DMV Demolisher

Abstract: The DMV Demolisher is a credential wallet, built using 3box, that allows you to selectively reveal any single credential your identity has been given. Our vision is a world where you only have to be verified by the State once before you are able to leverage any government service. Our system allows people to turn their MyColorado Digital ID or Driver’s License into a verifiable claim on their 3box account, using a secure chat thread to collect any necessary information before the clerk issues the claim. The principles and technology contained in this technology point towards an era of self-sovereign identity; wherein many sources of truth are used to evaluate personhood rather than some monolithic institution like the DMV.

DAOathon— Turn Hackathon Project into a DAO

Abstract: We the people walked through several ETHGlobal events found a sad fact: The sustainability of the hackathon projects is low. Those projects lack support from the hackers, the community and the organizers(typically the investor groups in the industry), after each event. Without sustainability, most of the projects become glittering gizmos down to the basement. 2020 is the year of DAO. In order to solve the massive adoption problem to attract next billion users, we develop a near bridge relay layer and telegram bot so that the end users can transfer, query and play with their ERC20 compatible token within a telegram group!

TallyLock

Abstract: TallyLock reduces the risk of election fraud by providing a simple and affordable way to notarize and lock election tally sheets on a public blockchain right when they occur in 3 simple steps.

Registered Notaries are added to the TallyLock Smart Contract as Authorized Notaries On the day of the election, right after the tally is performed the Notary takes a picture of the tally and uploads it to IPFS and the TallyLock Smart Contract where it’s timestamped and protected from tampering so results are not manipulated or changed in the future At any moment after the tally is performed, citizens can audit and validate the results

This process is currently performed physically, using expensive and insecure scanners or sometimes unreliable and expensive software.

Tally lock can also be used by Notaries to notarize any document on the go without carrying seals or ledgers. Documents can be made public on IPFS or a signed certificate can be produced for private documents.

Living Proof — censorship resistant attestations built on the ETH blockchain

Abstract: LivingProof makes it possible for journalists to keep their audiences informed with globally visible, easily consumable, censorship resistant attestations. Using the Ethereum blockchain, journalists can cryptographically attest to a message of their choosing with a time interval to feed the proof, creating a “”living proof”” as long as the proof is fed a new signature before the interval is reached.

Living Proofs can also be funded with Ethereum, making funds available for bounties on actions once a proof dies or funds available for payouts to predetermined recipients. This allows individuals and organizations to programmatically execute actions on the failure of meeting the conditions of life for a proof.

Each Living Proof comes with an embeddable badge for the owners website that can be shared across the web for awareness. This badge displays the status of the proof to the world in a familiar and easy to understand interface. A green badge means the proof is still living, a red badge means the proof is dead. While the proofs themselves are trivial, the ability to globally attest to one’s personal safety in a user friendly way can make a major difference to a journalist reporting on national corruption that does not have the means or desire to leave their country.

Next steps before launch: refactor LivingProof.sol for security and modularity, add multiple optional trigger contracts, improve global feed to feature Living Proofs that request publicity for increased attention.

GiveCrypto Pooled Micro Loans

Abstract: In the world today many people are trapped in poverty because they lack access to the financial resources needed to change their situation. For example, with a loan of $1,000, a farmer in Venezuela earning $20 a month today could move to Bogota and make $2,000 a month as an uber driver, a 100x increase in income.

For our hack, we worked with GiveCrypto, a charity focused on using cryptocurrency to enable economic freedom, to build a peer-to-peer lending tool that allows people to create micro loan fundraisers that can be used to finance these loans. This lets anyone easily lend funds to people in countries without good financial infrastructure, helping lift people out of poverty. Lenders not only help people in need, but also earn a small amount of interest on their investment. We are helping GiveCrypto run their pilot and have three recipients waiting for loans.

Flowerpot 🌻 *Finalist*

Abstract: Flowerpots are an easy and more open way to sustain projects & maintainers. GitHub Sponsors is marketed as a way to connect maintainers with the community who depend on their work in order to receive recurring funds to sustain digital infrastructure. Other platforms, like Open Collective, have followed suit — making an effort to provide new ways for people to fund free and open source software However, when GitHub Sponsors requires acceptance from a “waitlist” and Open Collective requires the formation of a legal entity, we become aware of the limitations of these approaches.

That’s why we built Flowerpot. Flowerpots are wallets that are linked to GitHub orgs. Maintainers and Members of Orgs can use Flowerpot to link a wallet to their GitHub organization. When linked, they can generate a markdown button for their READMEs. When clicked, these buttons automatically initiate a transaction to the Org’s wallet.

MetaCredits — Bootstrapping the truly unbanked into the ethereum ecosystem *Finalist*

Abstract: We want to create meaningful “on-ramps” into the ethereum ecosystem for developers with limited or no access to cryptocurrency. Our system is designed to allow these developers and their potential end users to be able to interact with the ethereum blockchain in a real and meaningful way (layer 1 transactions) without ever needing to own a single wei. The gas for their transactions will be paid by beneficiaries who are interested in growing the ecosystem and being charitable while feeling secure in (coded) guarantees as to how their funds would be spent by the benefactor.

We have robust and working smart contracts modeling this and have two separate front end applications (representing different user personas) to demonstrate our system design.

Urban-Bowl

Abstract: To feed today’s global population, we currently need a farm land equal to the size of South America. Despite the excessive amount of land already allocated for agriculture, an estimated 815 million people worldwide still sleep hungry each night. In addition, by the end of 2050 the worldwide population is estimated to be 9 billion. Modern cities of the world already have half the world’s population, which follows that the effect of projected growth in the global population will be drastically reduced by the habitable land to maintain modern infrastructure to extreme levels. Urban areas are not built for agriculture but a rapidly changing world already lacking land with hunger and agricultural difficulties inspired us to come up with a solution that can redefine the way we think about agriculture.

Urban-Bowl is a decentralized urban farming platform where individuals could lease empty spaces like backyards or basements to produce food using urban farming methods. Our platform incentivizes urban population into farming by providing them a decentralized marketplace to sell their fresh produce directly to consumers in their neighborhoods. We are focusing on impact track and our product meets the following UN Sustainable Development Goals:

Primary Market / A Simple Market Game for the Presidential Primary Process

Abstract: A simple market for buying and selling shares in candidates during the primary election process. There is no central order book or matching engine. Users buy or sell shares from a central counterparty. The dApp is meant for small groups of people, e.g. in an office pool. The number of available shares per candidate and the initial credit balance per candidate can be adjusted according to the size of the user base.

Keeping the total number of shares fixed encourages diverse strategies, e.g. put all your money in your favored candidate vs. hedge across multiple candidates. As the primary process goes on, the administrator logs outcomes according to which points are assigned to the users. The leader at the end of the primary process wins the game. The smart contracts were written in Solidity for the Ethereum blockchain using Remix.

DeFiat

Abstract: DeFiat is a fiat to any ERC-20 on ramp. As of December 2019, there were only 65,000 active users in the DeFi space. Yet, in the US alone, there are 327 Million fiat users. A factor contributing to the lack of DeFi adoption is the absence of direct fiat to ERC-20 bridge. By enabling fiat users to access DeFi directly, we can increase awareness and usage of the DeFi space. With DeFiat, we have solved this problem by developing the first USD to any ERC-20 on ramp. Users are able to input their debit card information and the ERC-20 they want to acquire and, in a single transaction, execute the exchange. The core problem that we’ve solved with this project is removing the need for a user to manually take ETH returned from Wyre’s onramp and execute a swap in a secondary transaction to reach their desired asset. By removing this additional step, we have greatly reduced the friction involved in onboarding new DeFi users. To build DeFiat, we have combined Wyre’s fiat onramp widget with Totle’s swap-and-pay functionality. The result is a regulation-compliant, non-custodial widget that accepts USD payments and automatically swaps funds into any ERC-20 (and, due to Totle Decentralized Aggregation system, at the best pricing available on the DEX market). To do this, we developed a smart contract which holds funds transacted by Wyre; funds held in this contract can only be retrieved by a defined address. By doing this, we can, in a non-custodial manner, execute a swap on a user’s behalf and send it the specified address.

Krypton.kitchen Rewards Program

Abstract: Krypton Kitchen is a small healthy food company that produces Kombucha, whole sells unique tea blends, and sells jarred fruits and vegetables from small farms in MA and VA. We’re adding a new product this week, Yerba Green Bars! We sold 45 bars this weekend to hackers and accepted crypto as payment via QR codes on our site.

What we built: A NFT token that is used as membership to our rewards program, giving any holders 10% off on our online store. We used OpenZeppelin 721 contracts as a template, added features to let an owner set an initial price for tokens, and let anyone buy them with a call to the contract. Then we added web3 to our website with a DappHero integration that checks a users balance and automatically applies discounts to their owner even if they pay with credit card or ETH.

Dappr

Abstract: Dappr is a decentralized dating app. Think Tinder, but on the chain. The app checks for a Metamask profile, if none is found, it prompts the user to make a Fortmatic account. Then the user is logged into 3box. Users match with others through swiping on profiles, they then can communicate with each other using a thread for 3 box chat. If the match wants to meet somewhere, both users will be prompted to stake $20 worth of Eth. If both stake then they will get their money back when they meet each other and scan the QR code on their respective phones. If one of the ghosts meets up they lose the stake.

Near DEX

Abstract: A DEX prototype based over NEAR blockchain using Rust contracts.

Details: 3 contracts were mainly deployed. One was of Fun token, another similar called ETHB and then I wrote my own contract in rust for an exchange. The contract has an orderbook, it allows the user to submit funds to the contract and then keeps a map of the orders. If an order matches another, it simply executes it. The video features the exchange contract getting executed on the terminal and then it moves on to the front-end for the exchange.

Future Plans: At the moment, its single player, needs to make it multiplayer and enhance it to a full-fledged dex.

Alfred by Team Hackers

Abstract: Alfred is a dApp for self-sovereign endowment that walks people through the steps necessary to create a “crypto will,” provides a consensus algorithm for generating proof-of-death, and enables executors to pay debts and distribute assets at the click of a button. With Alfred, people can transfer their cryptocurrency and tokens to crypto-natives and make it easily accessible to individuals who don’t maintain their own digital wallets.

Alfred combines data from a variety of sources including electronic death reporting systems (EDRS) run by state governments and the Social Security Death Index as well as obituaries and social media with a dead man’s switch that gives the executor, beneficiaries, and the allegedly-deceased a way to establish whether or not proof-of-death has been achieved. Once proof-of-death is established, Alfred gives the designated executor the power to settle the deceased individual’s outstanding debts and the smart contract distributes their assets to beneficiaries either “as-is” or settled for Ether thanks to our integration with Kyber.

Bound: A Patreon-style platform built on a tokenized bonding

Abstract: Patreon built on an out-of-the-box tokenized bonding curve. Fans purchase an artist’s token and gain access to exclusive content. Artists take a fee on every token purchase/sale.

Content creators are underpaid. Fans don’t have a meaningful and mutually beneficial way to directly support their favorite artists. Bound allows content creators to further monetize content in a novel way. Their profits scale alongside the growth of their dedicated fanbase, and the fans receive to major forms of value:

Enjoy the benefits of an exclusive “”club”” that provides access to premium content. For example, a musician could offer early album downloads, signed merchandise, Bound-exclusive concerts, etc. For as long as a fan holds the token, they retain access to all current and future rewards.

The ability to invest in and profit off of the speculative market around the future success of an artist. Early adopters are rewarded the most, but even those who might lose money by selling back into the bonding curve at a loss still support the content creator.

Artists are able to continually profit as long as people are buying & selling the token, and they are able to establish a more meaningful connection with their fans.

Medici *Finalist*

Abstract: Medici is a platform with Youtube and Twitch integrations with the ambition to grow to integrate with all content creation platforms. The platform enables both users and content creators to quantify important metrics on-chain such as; likes, views, subscriptions, time spent watching videos. These data metrics can then be quantified and represented on-chain via a point mechanism. The point mechanism enables reputation to be initially established and through reputation amongst users a closed loop economy can be established around this audience: ie through avenues such as a swag store or NFTs.

TemporalX IoT (TexIOT) — An IoT Mesh Network Framework With Bundled LibP2P & IPFS Video Streaming

Abstract: TemporalX IoT is an IoT mesh network comprised of multiple ESP32 chips, including an ESP32-CAM chip which streams a webcam on the meshnet. The meshnet is bridged to a MKR1000 board functioning as a regular WiFi network, giving the ability to route traffic from the meshnet to hosts on the regular WiFi network, although I didn’t get a chance to implement the routing of traffic, however the meshnet is bridged to the regular wifi network. Additionally there is a backend comprised of TemporalX, S3X, and a generalized LibP2P node. TemporalX + S3X are used to pull the mjpeg stream coming off the ESP32-CAM and does a few things:

Copies the output into a LibP2P protocol

This means that any libp2p host can stream the video coming off the camera

LibP2P video streaming, wat? :O

Copies the output into S3X

The entire video feed is stored on S3 + IPFS as a backup

Takes the data from S3X and streams it via a http server

Kettlecorn — Anonymous Eth 2 Deposit Dapp

Abstract: Our idea was to build a dapp that allows Eth holders that want to validate in Ethereum 2.0 Phase 0 an easy way to anonymize their deposits to the beacon chain deposit contract on Ethereum mainnet. We succeeded in compiling and deploying the deposit contract to Kovan along with uploading and verifying the source code on Etherscan. We also successfully used Carl Beek’s Ethereum 2.0 Toolkit to generate credentials to use with deposits to the deposit contract. We also modified and deployed an update tornado cash to Kovan to accept 32 ETH deposits. We also created a dapp to begin tying the workflow together to walk the user through tornado deposit, withdrawal, credentials generation for Eth 2, and then deposit to the beacon chain deposit contract.

We felt this historic migration of ETH from Ethereum 1.0 to 2.0 with consistent deposit/transfer amounts of 32 ETH could provide a high likelihood of anonymity for new and long time users of Ethereum 1.0 that have little to no privacy on the current mainnet.

Die Kitty Dai *Illia Polosukhin’s Choice*

Abstract: Send your Cryptokitties out on a raid in a massive boss battle. Each CK submitted performs an attack on the boss, and if the boss is still alive, the CK is turned into a Wrapped Cryptokitty and stored in the boss’s contract. When a Cryptokitty defeats the boss, the cat remains alive and its owner wins a ton of Wrapped Cryptokitties and any DAI submitted to boost the Cryptokitty in its raid attack.

MuckRaker — Shining Light A On The Truth

Abstract: Journalists are constantly persecuted for reporting on politically or socially contentious topics. Threats or other forms of intimidation have been used throughout history to enable established political structures to maintain their power and prevent dissidence. Repercussions for reporting can often go as far as physical violence or death, as in the case of Jamal Khashoggi.

How do we solve this? MuckRaker is a dApp that enables journalists to be anonymously supported by a set of patrons who would want to sponsor their work. MuckRaker enables patrons to search for journalistic works based on content, location, and a select few other tags. Funding is processed through MetaMask and Ethereum mainchain. Privacy is important in the latter steps of the journalist-patron interaction. Quorom Tessera is a natural choice for maintaining private smart contracts in order to submit project reports (the finalized summary for the work) to the patrons. This feature enables patrons to verify their journalists’ work without any potentially identifying information in the report to the

public.

How did we do this? We used IPFS for our distributed data store and Quorom for our permissioned blockchain system. The React front-end client displays the information and enables payments with MetaMask. Work needs to be done on better decentralization and privatizing transactions when possible. We were also looking into a chain-swap feature, where a Smart Contract on main-chain would issue events through an Oracle to mint and transfer money on our permissioned chain, and a similar flow would enable cash out.

Web3 x SAML — Unified Authentication for Web2 and Web3

Abstract: We built a bridge between Web2 and Web3 with a SAML identity provider. This enables users to sign into the thousands of SAML supporting apps using a KeepKey hardware wallet, and manage their user data via 3Box. A users identity is compared against a smart contract that manages the roles a user has in an organization and kept in sync across Web2 and Web3

Liame — Wallet Based Email

Abstract: Traditional email is not suitable for spam resistant, privacy centric and user friendly interaction.

Key things Liame is solving: 1. Data Ownership — Your wallet is your access to your emails 2. Spam — Every message sent requires blockchain authentication against user defined preferences. Every email is a unique hash that is thrown away after successful message send, no more guessable email addresses! 3. Privacy — Wallet based accounts mean public/private keys control end to end encryption 4. Autonomous Communication — Finally blockchain smart contracts can engage with users for meaningful decentralized application events. 5. User Experience — Using products like WalletConnect, simply scan into viewing your inbox.

We intended to add two features: 1. Email proxy — store a preference where emails could get forwarded. Useful if you have multiple wallets. 2. Decentralized network relay layer — Implementing similar tech to gas station network for generalized email delivery.

Why “Liame”? We reversed how email is delivered and controlled, seemed fitting :)

niftInsure

Abstract: niftInsure is a protocol that enables fixed term NFT insurance. The smart contract allows an NFT owner to request a quote for insurance on an NFT in exchange for a premium. If the NFT owner pays the premium (in DAI) they then have the right but not the obligation to sell the NFT to the insurer at any time during the term (American put option). The insurer instantiates the insurance contract with a pool of funds such that they must maintain a given ratio of assets to liability. In short niftInsure helps with NFT price discovery and liquidity while unlocking NFT lending with much stronger value guarantees!

LedgerLocker

Abstract: We recognize that decentralized applications strive to be ‘zero fees’ for transfers among users. However, there is no good way of monetizing the service as a result. How is it possible to monetize a smart contract for a service while maintaining 0 fees? Introducing LedgerLocker…

We built a generic staking protocol that allows smart contract owner to earn interest while maintaining account balances. Any DAI that is received from the smart contract can be directed to DSR where the smart contract owner is the recipient of the interest.

We want users to keep their funds but also allow smart contract owners to monetize their services through interest. Think POOLTOGETHER but instead the balance is going straight to the owner.

Any time DAI gets transferred into the smart contract, the smart contract will convert the DAI into DSR. The smart contract keeps a balance of the DAI for each user. As such, when a user wants to withdraw, the smart contract will take the DAI out from DSR and transfer it back to the user. The smart contract owner earns all of the interest generated by the DAI as payment for the service. In our smart contracts, we chose to use DAI, however we built our smart contract in a generalized way such that it can be extended to multiple lending tokens such as Fulcrum or Compound. Additionally, it can be abstracted to use ANY ERC20 or ETH and earn interest off of it.

AutomataDAO

Abstract: Our eminent interconnected world brings opportunities across various industries, but requirements of trusted and valid data sources are necessary.

We are creating a decentralized marketplace for a shared-economy of robot data and services. Users from around the world can explore our marketplace and purchase real time/streaming data or static data from a set of worldwide data sources (e.g. robots, IoT devices). With drones and mobile robots, we allow users to set navigation paths for autonomous navigation, and temporarily allow for the teleoperation of such systems.

In our platform, we leverage a ChainLink oracle that links data of multiple data sources that are present in a single location — for example, a set of drones surveying an agricultural field, or a set of temperature sensors. In turn, the Oracle can provide a single source of truth that provides harder guarantees on the validity of the data .

We leverage EtherMint for faster transaction time and to lower the gas cost of our smart contracts, as well as for interoperability and the ability to fine tune the state transition logic for our unique requirements. Our set of smart contracts enable the purchase of the data and enable permissions access to the machines.

Microverse.Life Cell NFT

Abstract: Mint, split, and merge NFT biological cells. Compete to make unique and special cells and avoid getting rekt!

Mint new cells directly from the contract at a cost of .008 per cell. Cell art is procedurally generated using the random values assigned during minting. The visual complexity of the cell depends in part on the total mass of the cell. Cells are minted with a mass of 8. Any cell with a mass of 8 or less is a level 1 cell. The mass threshold for each level is twice the previous level. A player may merge any two cells they own into a new cell. The genetics of the merged cell are sampled from the input cells based on their proportion of the total mass being combined. E.G. A cell with a mass of 8 has a small chance of influencing the genetic outcome when merging with a cell with a mass of 100. When merging cells, the resulting mass can vary greatly. The table below describes the probability of different mass altering outcomes. A player may divide any cell they own into two cells of smaller mass with identical genetics. The distribution of mass between these divided cells will range from 50–50 to 70–30 at most. The total mass of the resulting cells is equal to the mass of the parent cell.

Abstract: Content creators can use this component to monetise their content. A content-creator can use our component to set an address, an image (although we believe this could expand into other media) and a payment amount. Our component will then blur the content to obscure it. Paying some ETH will remove the blur and make the content visible. Imagine an artist monetising an online exhibition, an illustrator ensuring they get paid for their work. Maybe some of the Spankchain performers could also make use of this…

jquery examples using dapphero static data in a dynamic way

Abstract: In my project, and most, users will need to make UI decisions based on onchain data, like how many tokens people have, whether they are logged in, or what the result of contract calls are. There are no docs on exactly how to do this yet on DappHero, and all the values grabbed from contracts are easier to get, but inserted statically in HTML. I forked an existing tutorial on simple contract calls and made 2 examples of using jquery (with many comments) to make dynamic decisions based on whether users have tried to log in and handling results of contract calls.
