Polkadot 2022 Annual Developers Conference will be held in Lisbon from November 28th to 29th. This event brings together a diverse developer community built on Substrate, as well as everyone who is interested in understanding blockchain development, to accelerate Web3 The development of this creates an ideal environment for knowledge sharing.
DeFi
Since the first developer conference, more than 8,000 people have registered and participated in talks by more than 100 speakers, Polkadot founders Gavin Wood and Robert Habermeier, and core developers
. Whether you are a developer who has already used the Polkadot technology stack or a novice who is just getting started, you can learn more in-depth in the conference.
Therefore, these platforms are of great significance to project teams. A complete system will help them benefit from existing tool libraries, underlying architecture, and development resources to improve their projects and accelerate project development. At the same time, the innovation brought about by the exploration based on cutting-edge technology also contributes to the ecological development of Polkadot.first level title
First place: RoboFi
The current project describes one of the applications of Robonomics for building a decentralized financial infrastructure (DeFi) to enable economic interaction between service robots without intermediaries.
Therefore, RoboFi combines the concepts of robots and DeFi (RoboFi = short for Robo[tics]+[De]Fi)
. “Robots” here refer to a broad range of entities (energy machines: power plants, ESSs, electric vehicles, drones, etc.) that turn energy (clean/green electricity) into work to create new sustainable value.In the RoboFi robot economy ecosystem, there are two robotic entities, namely two service robots (Robot Werther and Robot Alice), that provide commercial services to humans and other robots, such as commercial delivery services, retail services, repair services, charging services wait.。
One of the robots, Robot Werther (Energy/EACs Generator) also has a solar power plant that produces clean (green) electricity. Robot Werther carries out its tasks of providing the service and, if necessary, receives payment from its own solar power plant.
In addition to direct electricity consumption, when a power plant generates 1MWh of electricity, an EAC/REC (Energy Attribute Certificate/Renewable Energy Certificate), which confirms the fact and source of this electricity, is an independent Digital tradable assets.
Submit a project to build a Polkadot-NEAR cross-chain bridge under the Web3 Grant Program
Second place: Polkadot Acala aUED Credit CardThe Acala Credit Card (powered by CryptCard) works like a standard credit card, except that it uses aUSD as currency instead of fiat currency. Additionally, cardholders use their Crypto wallets to swipe rather than plastic cards, making this payment method more environmentally friendly.
Acala Credit Card at CryptCard produces credit cards that transact in Crypto instead of fiat currency. Operate card application systems and payment gateways while connecting merchants, lenders and cardholders.
picture
Each applicant is processed by an Acala credit analyst based on the applicants credit score
. The higher their score, the lower their interest rate and vice versa.
Consumers dont like to pay for shipping, and for most users and developers on Ethereum, they are suffering from exorbitant gas fees. Besides, Crypto is not widely used yet, so-called Crypto credit cards only provide Crypto is used as a reward, so Acala Credit Card proposes a solution to the current pain points in the Crypto field:
- Issue the Acala credit card, allowing anyone to spend the aUSD stablecoin without paying for gas.
Through Acala, cardholders are provided with a credit line, while obtaining up to 20% income (interest), enabling Crypto consumers to spend on credit.
Acala and Polkadot projects can sustain themselves by accepting this Crypto card as a means of payment.
This card can attract existing Ethereum dapps to migrate to Acala or Polkadot.
The next step for the Polkadot Acala aUSD Credit Card is to launch this true Crypro credit card for the benefit of all, especially in preparation for the upcoming recession.
Third place: Humidefi
Humidefi is a decentralized financial center for UMI and PHPU. UMI is its native token, while PHPU is a collateralized stablecoin pegged to the Philippine peso.
As a decentralized financial center, users based on the application will be able to:
Buying Crypto: Users will be able to buy UMI and PHPU using facilities like Transak and GCash. GCash is a well-known electronic payment application in the Philippines.。
Pay with Crypto: Users can pay directly at any Filipino goods and service provider. They can even pay utility bills and other government payments.
Investing in Crypto: Through UMI, they can invest in staking pools and even parachains and parathreads in the near future. Humidefi will also create a facility for depositing and lending PHPU to users.
Humidefi supports smart contracts. This enables local developers to leverage their talents to make dApps without paying USD
NFT
Through Crypto and blockchain, Filipinos can use decentralized finance to manage their finances and solve the problem of having to pay high remittance fees in the past.
In addition to regular Filipino users and investors in Crypto, Humidefi also focuses on local developers who cannot afford to deploy Web3 applications because they only hold local currency. Humidefi will unlock their potential and may join the global Web3 developer pool in the future.In the future, Humidefi will continue the mainnet roadmap, and will cooperate with the local developer community, as well as existing customers and users, to expand the scope of adaptation of Humidefi.

First place: Moonsama
KodaDot is the first NFT gallery to implement the RMRK standard based on Kusama
, as KodaDot hopes to implement various NFT standards in the Polkadot ecosystem, the KodaDot team took this opportunity to test their thesis with the Moonsama NFT contract.
This will help integrate EVM into KodaDot for fully compatible deployments on MoonRiver, Moonbeam and Astar.
KodaDots submission extends KodaDots ability to gain insights from Moonsama (Moonsama can be understood as Moonriver or Moonbeam ecology) contracts running on an EVM parachain called MoonRiver in a friendly end-user user experience.Users can browse through a set of various collections in the Moonsama multiverse and view the properties of NFT items and their on-chain historical activity for each item.。
Within each collection, users will be able to search at the top of the collection, view collection history with specific events selected by the user within it, view top holders and which NFTs are currently owned by each address, and earn through NFTs.
KodaDot used SubSquids state-of-the-art EVM indexer to integrate ERC-1155 NFTs without breaking the entire KodaDot architecture, saving a lot of time.
After winning the first place in the Polkadot North American Hackathon NFT track, the team plans to integrate another series of functions into the KodaDot EVM,
Therefore, users can search for NFT through the rare resource manager, and trade their own NFT through the market contract
Second place: Sociable WeaverThe original intention of the Sociable Weaver team was to create a purposeful UI and demonstrate the usage of various NFTs, using them as tools to understand and simplify complex nested structures in an intuitive and easy-to-understand manner.
So the team created an interactive UI that allows users to create and attach NFT collections, add NFT properties, and seamlessly nest them into nested trees. Users can create new NFT collections with a single click, define their properties, and add or remove permissions for each collection before appending them to any available collection.
Users can attach one NFT to another NFT and form an ownership relationship. This makes it possible to create complex NFT nested structures, which users can restructure to their liking at any time. This also makes it possible to transfer ownership of an entire subtree to another person or another NFT.
Sociable Weavers solution has unlimited possibilities, from individuals to organizations, to segmenting complex enterprise business systems, and it can even be applied to a countrys system
. Sociable Weavers possibility of systematizing and dividing, connecting and grouping items is of great use in all parts of modern society.
Sociable Weaver is built using the Substrate-based NFT chain Unique Network in the Polkadot ecosystem.
Third place: Ventur NT-NFT Pallet
The Ventur NT-NFT Pallet is a Substrate module that implements non-transferable NFTs.NFTs generate enormous value by creating a decentralized, distributed representation of digital ownership. While the traditional paradigm of NFTs has had great success as a solution for assets with transferable ownership, such as artwork or even real estate, it is not suitable for assets such as credentials and memberships that need to be tied to a specific entity. Assets such as these require the implementation of non-transferable NFTs (NT-NFTs).。
Ventur NT-NFTs solution is to implement non-transferable NFTs in the Substrate Pallet. At its core, its Pallet is based on Substrates existing open-source Uniques Pallet. From Uniques base NFT implementation, Ventur strips transferability and models new functionality for proposing and accepting NT-NFT allocations.
Proposals and acceptances are intended to prevent distribution of unwanted spam NT-NFTs to individuals.
Additionally, the team added an optional expire value specifically to support temporary credentials and memberships

andcommunity choiceAlthough NFT has only started to shine in recent years, its development speed is very fast. It took only one year to expand from a market of about 100 million US dollars in 2020 to a market of 10 billion US dollars in the past two years.
and
From its positioning point of view, NFT can represent far more asset attributes and types than Crypto
, if compared with real assets, the actual value of tangible or intangible assets or rights and interests similar to NFT is much greater than that of currencies similar to Crypto. Then, it can be foreseen that the future market of NFT will be much larger than that of Crypto.picture。
However, the current development of NFT can only be said to have made a good start. Although the market scale has developed rapidly, the development of NFT applications is relatively early.
Although ordinary users can easily issue simple NFTs, such as uploading pictures as an NFT, etc., if you want to design NFTs or NFT groups with more attributes or more complex logic, and combine more business models, This is a bit difficult. Therefore, tools that can meet the large-scale use of NFT in the future will be a key element in the development of NFT.
As we introduced above, Sociable Weaver is one such NFT tool.
It is an interactive UI that allows users to create and attach NFT collections, add traits and properties, and nest them seamlessly into nested trees
Standing on the shoulders of the Substrate-based NFT parachain Unique Network, Sociable Weaver has also received corresponding attention and support. It is not surprising that it won the first place in the community.
Second place: Rooster DAODAO has been a relatively popular track since last year. Since the well-known capital a16z invested in FWB in October 2021, it has triggered discussions and research on the direction of DAO by many institutions and organizations.Subsequently, an organization called ConstitutionDAO bid for a copy of the U.S. Constitution through crowdfunding. Although it failed in the end unfortunately, ConstitutionDAO also introduced the new organizational form of DAO to let more outsiders know about DAO. Many DAO projects in the world have also emerged as the times require.
Among them, the Venture+DAO model similar to FlamingoDAO and PleaserDAO is being actively explored and has become a more popular subdivision direction in the DAO field.And Rooster DAO in our last article
A review of the Polkadot North American Hackathon winning projects (Part 1)
, is the second place on the DAO track.
It is an investment fund managed as a DAO that focuses on investing in Polkadot ecology. Users can put forward some investment proposals by participating in DAO
, if the investment eventually yields a good profit, the proposer of the proposal will receive a small amount of profit from the investment as a return.
The project is not only a popular Venture+DAO model, it supports anyone to participate, and it also has a certain return on investment. It also stands on the shoulders of RMRK, so it is conceivable that it can get such support from the community.
Third place: NUSICMusic intellectual property (IP) is an intangible asset, and remuneration for the use of music is considered to be protected by intellectual property laws related to copyright, but in practice, remuneration for music creators is determined by an oligopoly, a minority big buyer.。
The power of these buyers has resulted in an asymmetrical market in which the big labels have historically been profitable, while the average performer earns less than the median salary.
While the Music Modernization Act passed in the US in 2018 sought to change that, it led to the creation of the Mechanical Licensing Collective (MLC), long criticized by independent songwriters as a black box collection. The plan is currently controlled by Sonys ATV, Warners Chappell and Universals UMPG Group.
The black box of music royalties means that revenue cannot be distributed.
MLC has received $424 million in music royalties from digital streaming platforms (DSPs), money that is supposed to go to artists, but no one actually knows who it belongs toSo, is there a way to align economic incentives around an open music data so that a set of data standards can emerge that benefits every music rights holder?。
NUSIC is working to achieve this, by creating tools that enable the independent long-tail artist community to benefit in the same way as traditional rights holders and superstars, while providing fans with a deeper level of engagement than ever before.
With the rise of short videos like TikTok, music consumption has changed. In apps like TikTok, where the vast majority of fans are only familiar with the catchy 15 seconds, TikTok is redefining how music is used.
Therefore, NUSIC can face such new needs and attribute the split part of the track to the song
NUSIC has teamed up with Web 3.0 native meta-artist YATTA, who is offering full commercial rights to parts from her upcoming debut album HAIKU.
The track Mystery of the Floating Pagoda is available as an NFT set of 32, split into vertical and horizontal axes, meaning that individual loops can be split from the main track as their individual instrumentals, along with each part of the music, Namely the intro, the verse of the song, the chorus, etc... This opens up many possibilities for NFT holders, including the option to use the music NFT in a short video, as a remix or as part of a brand new song.picture
Available on Moonriver’s NUSIC marketplace and priced in MOVR, the track is the first to be released as a collection of music NFTs in this short format, with all metadata stored on NUSIC’s Layer1.
With the first version now available on Moonriver, NUSIC is ready to launch more music assets on the same network as a technical and economic test case. The auction feature may prove to be a welcome feature, and some thought has been put into implementing it.
The ability of the Metaverse to revitalize music is the next frontier for NUSIC, and music may prove to be a more appropriate asset class for Metaverse than the arbitrarily scarce land that defined our understanding in the early days of Metaverse.
postscript
Engaging more rights holders, from major publishers to self-published artists, is a priority as we implement Layer1 and expand the liquidity protocol. Utilizing the certification network through KILT, NUSIC DAO can be established as a decentralized music regulator.The music industry is eager for the new revenue opportunities created by Web 3.0. By plugging in key stakeholders, transparency can be enforced, and new music standards will have the opportunity to iterate and gain traction in a competitive and fluid market.first level title

On the DeFi track,
The DeFi of the Polkadot ecosystem is no longer limited to the financial behavior on the chain, but has already entered the real world
, trying to use the advantages of blockchain technology to solve many real-world problems.
There are not only cases of providing a digital trustless environment for a physical industry such as robots, using DeFi in all aspects of the industry; there are also applications that focus on providing DeFi services to people in a certain country like the Philippines; there are also applications based on the Polkadot ecosystem. Stablecoins make credit cards and support real-life ones.In fact, compared to many DeFi projects with serious homogeneity on other Layer 1 public chains, Polkadot as a Layer 0 has greater scalability. Therefore, in terms of DeFi expansion, the Polkadot ecosystem has gone out of its own way of thinking , more blooming, this is also the difference between the Polkadot ecology and other public chain ecology.。
On the NFT track, the Polkadot ecosystem still focuses on the construction of tools and infrastructure. Only with these prerequisites can the birth of more NFT projects be supported. It is worth noting that it also includes the NFT of the currently popular SBT concept, that is, the soul-bound NFT, or non-transferable NFT.
In addition, more and more Polkadot projects are getting out of the vicious circle that is only limited to the game within the circle. When some emerging Layer1 public chains are involved in other Layer1 public chains, the Polkadot ecosystem has jumped out of the original thinking and actively expanded user experience. The possibility of Web3 solving real-world problems. Among them are some enterprise-level parachain projects dedicated to serving entities, and some are Web3 projects initiated by entity enterprises or organizations to solve real-world problems.
The Polkadot network is booming and ecological projects are emerging one after another. The Polkadot Ecological Research Institute focuses on Polkadot ecological trends and grasps current trends. Reply to [Daily] to get the latest daily news summary of Polkadot ecology.
*The information provided by the Polkadot Ecological Research Institute does not represent any investment hints. The published articles only represent personal opinions and are for reference only. Since there are no policies and regulations related to digital assets in China, users in mainland China are requested to pay close attention to the development of Crypto.
Welcome everyone to join our Telegram group of the Polkadot Ecological Research Institute:
When other public chains are still playing in the stock market, Polkadot is already expanding into new incremental markets. Although it is cold winter, construction cannot be stopped. Lets look forward to what kind of flowers Polkadot will bloom when spring comes.
