Multi-Chain AMM and Yield Farm With Innovative Features. On #ONE Moonriver: https://moonriver.padiswap.com - Mainnet is Live
Launching a DAO is not easy for newcomers in blockchain due to the technical difficulty of blockchain principles. Hotpot Network provides easy launching steps for people outside the blockchain world to start a DAO within a few clicks. Any newcomers can design their token economics with our user-friendly configuration interface to address the goals of different communities. Our platform consists of multi-chain support for smart contracts, a user-friendly web interface, SDK, and various toolboxes for different DAOs. Moreover, the platform itself is also a DAO, all the decisions and executions are supervised by the hotpot community. Hotpot is a blockchain-native DAO-launching platform. We guide users through an interactive, tutorial-style procedure to design token economics for DAOs. We use bonding curve, a general case of automated market maker algorithms for the token economics design. However, it is non-obvious for users to understand different key parameters in token economics design. Instead, we use an artificial intelligence-powered system to search the optimal bonding curve parameters. Users only need to describe the intended DAO market cap at different stages. Then, a bonding curve-based smart contract can be deployed immediately, at no cost. Most existing DAO projects are using Liquidity Pool or NFT based principles for governance. However, bonding curve could be the optimal way for DAO launching as proved by constitution DAO, Assange DAO. Governance token based on bonding curve lacks sufficient community support, which prevents users from diving deep into this type of AMMs. Hotpot aims to help users learn and launch bonding curve-based tokens through artificial intelligence-powered interactive sessions, and provide them similar swaps functionality as Uniswap.
# 基于IPFS解决疫情期间核酸检测结果问题 **问题：** 我们知道将核酸结果保存到数据库里，可以通过连接数据库的方式以及提供查询核酸结果的Http服务，但是核酸结果的数据太多太多了。截止2021年末上海常住人口为248943万人，一次全员核酸就大概有248943万条结果数据，而且不止一次，试想Http服务崩溃了会是什么样的可怕结果，也许解决分布式存储的技术有许多种（HDFS，Ceph，GFS，GPFS）等。 **选题：** 考虑核酸结果不涉及到隐私的情况下，我们选用IPFS，因为它是一个点对点，全球的分布式文件存储协议，他跟Http搜索是不同的，他是按照内容地址进行搜索， 它可以将核酸结果随机存储在各个节点上，用户只要有这个hash地址就可以在节点上找到自己的核酸结果。所以IPFS可以保证数据持久性和安全性。 **技术选型：** 后端1：基于java语言提供给核酸机构的核酸检测服务。(SpirngBoot+jdk8+mybatis+mysql8)。 后端2：基于rust语言实现IPFS存储核酸。(rust1.6+ipfs+tokio)。 前端：基于vue语言针对后端服务所提供的api可视化提供给核酸机构进行核酸业务相关操作。 **最后我们希望能早日战胜疫情，恢复正常生活。**
## Project Name Hyperspot Tool ## Overview Hyperspot is a fixed-rate lending platform. A fixed interest rate is different from a variable or stable interest rate because the interest rate does not change over the term of the loan. ## Features It will be a challenge for users to match loans to each other under the exact conditions.Because of the large pools of liquidity, banks have traditionally acted as intermediaries - charging high fees - for borrowers and lenders to interact with them.Hyperspot eliminates intermediaries and maintains on-chain pools of liquidity that are readily available as off-the-shelf counterparties for individual users. ## Advantage ### 1.Enabling Fixed Rates in the Crypto Ecosystem hyperspot makes it possible for anyone to lend or borrow crypto assets at a fixed-rate of interest at any time, from anywhere in the world, in just a few clicks. Unlike other protocols that just serve lenders at fixed rates, or only offer volatile, variable interest rates, hyperspot serves both sides of the fixed-rate borrowing and lending market. ### 2.fCash Behind the scenes, hyperspot introduces a concept called fCash to make this happen. fCash allows hyperspot to tokenize payments in different currencies like ETH or USDC at specific points in the future. fCash is what hyperspot uses to keep track of who owes what, who is owed what, and when. For example, on hyperspot, two users can enter into an agreement where a lender gives 100 USDC to a borrower who promises to repay 105 USDC on December 1st. fCash is how hyperspot defines that future payment of 105 USDC from the borrower to the lender. Here is how hyperspot keeps track of the future payment from borrower to lender using fCash: The lender receives +105 December 1st fUSDC (an asset redeemable for 105 USDC on December 1st) The borrower gets -105 December 1st fUSDC (an obligation of 105 USDC due on December 1st). The exchange rate between USDC and fUSDC at the specific maturity represents the fixed interest rate that users receive on hyperspot. ### 3.Liquidity pools It would be challenging for individual users to match on exact terms to borrow and lend with each other. With large pools of liquidity, banks traditionally act as an intermediary that borrowers and lenders interact with - for a hefty fee. hyperspot removes intermediaries and maintains on-chain liquidity pools that serve as a ready counterparty for individual users at any time. Liquidity pools hold cash, like USDC, on one side, and fCash, like December 1st fUSDC on the other side. Lenders put their USDC into the pool and take out December 1st fUSDC at the prevailing market exchange rate. Borrowers put December 1st fUSDC into the pool and take out USDC to use however they wish. Collateralization hyperspot guarantees that lenders earn the returns they expect by ensuring that borrowers pay back their debt at maturity. hyperspot requires every borrower to first lock in high-quality assets like Ether and wrapped Bitcoin to act as collateral - much like how a bank might use your home as seizable collateral on a mortgage. This means, for example, that a user who wants to borrow 100 USDC will be required to hold collateral that is worth at least 150 USDC - a minimum collateralization level of 150%. The amount of collateral that borrowers are required to hold against their debt varies based on the risk level of their collateral - DAI only requires 120% collateralization, while ETH requires 150%. ### 4.Liquidation Enforcing these collateral requirements ensures that borrowers on hyperspot can’t simply walk away from the debts they owe. However, instead of the bank repossessing an entire home in case of a mortgage non-repayment, hyperspot’s liquidation process can sell, or liquidate, partial amounts, so that borrowers maintain their collateral requirements without losing all their collateral. This only becomes necessary if the value of their collateral drops below the required level due to market fluctuations. In the unlikely event that borrowers are not liquidated quickly enough due to market volatility, hyperspot can use the protocol’s own reserve assets or sell its native token, the NOTE, to raise the capital necessary to make sure lenders are always made whole. hyperspot is a sophisticated system, but the value proposition that it delivers is simple: hyperspot delivers access to secure and efficient fixed-rate loans to anyone in the world by removing financial intermediaries with the Ethereum blockchain. ## BSC chain deployment address 1.Market:0x31607Bc5b21cD8DcE667d0f33Cf8cE0E834a70cd 2.Dai:0x3E9C2e29c71A067DE30C6838329B9406698F061b 3.ETH:0x1bE2BED376AC0afeB800e36Be080823dc8e330Cb 4.USDC:0x3e906751265955127f4Bc951C6dBBaaA94028941 ## Some Links: GitHub:https://github.com/hyperspot/Ontology-Hyperspot Contract:https://github.com/hyperspot/Ontology-Hyperspot/tree/main/contracts Front end:https://github.com/hyperspot/Ontology-Hyperspot/tree/main/Hyperspot-Front-end UI:https://github.com/hyperspot/Ontology-Hyperspot/tree/main/Hyperspot-UI ## Youtube https://youtu.be/i4cJ8GiyB9E
# The Impact App, by Eco Labs **Why** Lack of low cost MRV solutions are a friction point that prevents impact projects--especially small scale projects--from scaling quickly. There is a growing number of people who want to take action to help regenerate our planet, land stewards who need more sustainable & resilient income, and communities who need to restore their local natural resources and build resiliency. At the same time there is a growing amount of capital being raised to fund impactful activities. NFT fundraising, individuals who care, & companies who want to reach net-zero, increase their brands cultural significance, or are operated by CEOs who care. More and more markets for ecosystem services are being developed. As Nori founder Paul Gambil says "demand is not the problem, supply is". How can we reduce the friction of these two forces connecting? Those who want to fund impactful activities (funders), and those who want to get paid to take impactful action (impact actors). This app & platform aims to address this, by aggregating all existing solutions, guiding impact actors on exactly how to start taking action, and building custom methodologies in coordination with funders which utilize plug & play data collection tools built into the app. **What** This application will serve multiple functions: - index/directory of all actions one can take which already have a funding counter-party and an existing MRV methodology. - step by step guide on exactly how to utilize existing methodologies and start getting paid to make an impact. - register and verify information about it's users in order to filter what actions that individual can feasibly take part in, such as location, expertise, access to land + size and existing resources on that land, access to a vehicle, physical capabilities/disabilities, etc. - collect data for custom methodologies using in-app tools such as images, video, location, audio, & temperature. Upload that data in public and transparent formats such that anyone is able to verify and cross reference. - integrate with mobile compatible blockchains such as Celo to facilitate in-app payments to impact actors. - provide resources & clear pathways for impact actors to obtain additional equipment or expertise which can increase the quality of data collected / increase pay. This could take the form of classes, obtaining certifications, purchasing IoT sensors or specialized measurement equipment needed to unlock higher paying methodologies. - optionally re-direct funds paid for impact actions to purchase products in-app, such as dynamic NFTs which can showcase & illustrate ones impact over time, and merchandise / accessories / tools which aid the impact actions (UV-protective clothing, knee-pads, gloves, tools tailored to specific methodologies) **When** Spring/summer 2022 - team building, customer discovery, hackathons (ex: Activate x Wormhole), grant applications. Major goals: build the MVP directory/index of existing impact actions, secure a total of $1.2m in funding, refine revenue models, research target market, obtain legal advise on entity structure / risk assessment, hire developers to start work on an MVP, bring on initial team members and advisors Fall/Winter 2022 - incubators, accelerators, app development, planning, MVP. Major goals: go through ReFi Venture Studios accelerator program, develop customer methodology pilot program with 10-30 coffee farmers in South America (in coordination with CCC), secure partnerships and integrations with other MRV providers and educators. Finish MVP (only functions 1 and 2) Spring 2023 - Fully operational V1 App launch, including functions 1-5. Summer 2023 - V2 launch including all 7 functions
### What is Portales? <br><br> Portales is a Cross-Bridge solution for fast wrapping assets. Portales' long-term goal is to make off-chain event listeners (Oyentes) decentralized by incentivizing node maintainers with PORT tokens. <br><br> ### How does Portales work? <br><br> <p align="center"> <img width=60% src="https://user-images.githubusercontent.com/78161484/168197981-7ff9e8da-298d-4b66-8699-4b40e884053c.png" alt="Portales Front"/> </p><br><br> A user wants to bridge assets between two chains. By interacting with Portales Front-End DAPP, it is possible to send a request using a Crypto Wallet (i.e., Metamask) to the Portales Smart Contract requesting a cross-chain swap to initiate. Upon receiving the request from the user, a transaction is sent to the blockchain resulting in a **SwapStarted** event.<br><br> <p align="center"> <img width=60% src="https://user-images.githubusercontent.com/78161484/168384700-15278661-a4a3-401f-94fe-bb205e8e374a.png" alt="Portales Front"/> </p><br><br> A listener instance called Oyente leverage [Ethers.js](https://github.com/ethers-io/ethers.js) ability to filter EVM events to monitor all **SwapStarted** events originating from a Portales Smart Contract and handle these as user requests for a cross-chain swap. Oyente is responsible for calling a **fillSwapRequest()** function on the target chain. There are four possible states for a transaction once Oyente catches a new **SwapStarted** event:<br><br> - **Initiated**: Oyente received a new **SwapStarted** event and just started processing it - **Error**: Oyente was unable to process the request, or the target chain reverted the transaction - **Processed**: Oyente has sent a transaction to the target chain, but confirmation is still pending - **Finalized**: The swap transaction is confirmed on the target chain<br><br> Oyente is also responsible for populating a database with the following data:<br><br> - **Oyente Event ID** - **Sender Address** - **Receiver Address** - **Origin Chain ID** - **Target Chain ID** - **Tx Hash** - **Tx Status** - **Transfer Amount**<br><br> Our authorial API will make this data available for the front-end so the end-user can follow the transaction status live on the web app.
# About ZClub <ZClub is the first-ever audio-focused Web3 social app that enables everyone across the global to profit from their social networks and activities. All you need to do is to get an NFT to start, and build your social connections in the Social-Fi and Game-Fi app. We aim to make a difference. In traditional pay-to-play platforms, users are the ones who support, post and pay to use social media. But these platforms never share its money and profits, and are the only ones benefiting from its user base. However, ZClub is going to change that and become the next-gen mobile application that enable users to socialize to earn and give money/profits back to them. By equipping themselves with NFTs in forms of Seats or ChatRooms, ZClub users will be able to host events, or welcome friends, guests, and social influencers to communicate, and engage with each other to earn in-app tokens, which later can be used in-game or cashed out. - Why does ZClub Share Revenue? We do not want users to remain silent or their needs to be overlooked, because they are the vital life force of platforms, and should be rewarded for their contributions, and their assets should not be stolen away by platforms. Also, we want to transforms how the social media works. We believe socialize/talk to earn mechanism can make normal users feel valued and thus inspire other business and companies to do the same. <br> - How does ZClub Share revenue? We adopt blockchain to do so to ensure everything to be transparent so that users know exactly how everything works. We do not profit from selling ads or sensitive user data. We only took a small tax from in-app activities, such as NFT trading, NFT minting, or NFT rental, giving over 90% of the revenue back to users and DAO members. <br> Our purpose is to be the leading Web3 audio-focused social app, enabling the mass to turn their social network into profits, and earn revenue share from social activities.
