 all your team members on the call and you're ready to start. Fine, yes if you allow me can I share my screen? Yes please and just to let you know when you start your timer will also start you will have six minutes for presentation three minutes for Q&A. Thank you very much can you see my screen now? Yes. Okay so let's begin. Thank you we are Alfonso, Ramses, Jorge, Beatriz and we shall present you BC4IC. The problem is the institutional life harms children but children should grow up in a family environment. If not possible the state assumes it's not possible the state assumes their responsibility to provide protection and assistance. Institution lack instruments to properly save work children and coordinate among themselves. When raised there they suffer from structural neglect and abuse. The object is to provide less time with better quality of life. Thank you and the solution is an effective remedy in a blockchain-based legal instrument that identifies stakeholders, structures legal information, interoperates agencies, facilitates oversight and gives children back their voices. This new legal paradigm ensures every child is well accounted for, empowers effective and efficient operation for institutional stakeholders, shares the asset of trust for legal information and gives children the opportunity to be informed and regain their voice. It's interesting and important to show you that there is a strategy, it's not only a tool but it's a tool for institutional development. We found out that using the icons of hyperledger it was much much easier to engage different partners that do know about development. We forged alliance already with the state of Jalisco. It's one of the 32 states of Mexico and we have in writing they're willing to cooperate and we are in the track already for UNICEF funding development. We have developed an initial instrument that you show it in the demo and then we'll have with the institution's workshop for user-centered design thinking development of the tool together during a year that's our project and that's the instrument development in the roadmap. What is the business architecture? We have identity, child legal record, agencies interoperability, government and society oversight, child participation. We have the layers of software for infrastructure. We began and we sold us many of the difficulties even in the rocket chat for BAF, okay, and mini cubes with pots already, but then we wanted to give you a brief description of the functionality and the architecture and we use fabric samples straight from the page. The programming would be done along the year with the workshops in the institution. The roadmap is there. We'll have workshops, pilots, workshop, pilots, and we'll continue doing during the year. This is an example of the demo. We define the screens for identity to register both NNA are the children to define the consortium of agencies so that we can using these icons off of hyperledger fabric documentation we explained to the institution and the stakeholders and we will teach them. We will teach them what we're doing as we're doing it so that they can work with us and they can appropriate the instrument. So when the instrument is finalized it belongs to all. It's not something that it's imposed on the user but it is developed by the user, okay? So we have all the screens will go fast and the interesting thing is as we go through the screens, okay, we can show directly what happens once you hit one of the options. In fact, I think this is another idea that we came across in the hack, which is we should do what we would like to do a drag and drop click and launch hyperledger fabric, okay? Like a scratch of Mitch Resnick, okay, bought with hyperledger. That would engage the institutions. Here you have for instance the Child Legal Record which is something quite interesting, okay, because it has an inner logic of issue, rules, facts, evidence and with this one institution can bring another institution and have the four that are needed for the project. Among many, we are beginning and this year we'll have four institutions. Now we need the screens. Tramsist, you have the floor. Tramsist. So hi, hi everyone. Okay, well, yeah, can you hear me? Yes, we do. Do you tell me when you want the next? Okay, well, in technology we don't... Okay, it's clear. Okay, well, technology, which is that technology to share this information about the blockchain, we're going to use, we're going to use, we're going to use different peers on different organizations. In this case, for example, we are getting, we are installing this DLD into the Linux, Ubuntu Linux, using this, that. Well, in this case, we're going to use the framework, the framework bath, blockchain automation framework, because it's a blockchain automation framework that has the all the, has the all, the all... Hey, hey, hey, sorry to interrupt. It's six minutes up for your demo. Okay, we'll go fast for the screens. The screens are there. The call. Hey. Hey, so you're, whenever you're ready, your time will start. You will have six minutes for presentation and your demo, three minutes for Q&A. We will hard stop at every interval. Mike, do you want to start this or not? No, go ahead. I'll keep this all on the presentation only here. Okay, what I'm going to do is start from our, our PowerPoint. We didn't quite... Work like crazy didn't quite get there. Apologies, you know, we've got some stuff working, but not 100% of where we're trying to go, but let me show you from the diagram to have a run the UI for it and so on. Your time starts now. Okay, so, well, I gotta share my screen first. Okay, so where's my, there's a diagram. Hello, there it is. Okay, so if you look at this, what we created is a, first of all, our environment is object-oriented where the classes and objects are on the blockchain and they're referenced by unique object IDs that are created, and that's what we use for the keys as you would in a regular key database. So as a result, we can do all sorts of interesting inheritance type capability. So we created accounts and we created a concept of apart and concept of assembly. So parts and assemblies and they have certificates and all this data actually exists and then you would be able to create this type of thing where a part becomes an assembly and suddenly become a product where a product is still an assembly and the idea would be that you would then be able to trace backwards from the customer account all the way backwards and forwards from any supplier forward for in case if you ever had to do a recall or anything like that. So user interface to it. So the concept of the user interface is, and by the way guys you can jump in real quick we only have a couple minutes so feel free. So the idea is you're viewing it from the vendor. So the idea is you're a company in a B2B situation. You've got vendors, you've got customers. So you look from the vendors, look for the customers, and then this rolls so that the vendor tree if you move up and down the supply chain you always see one up one down. And that would be the idea. And then you would say to your vendor I want to order an assembly and you order it, you want to order a part, send a part to you. So it gives you a list of what's going on. You can also create locally if you're a your own vendor you also want to produce for your own parts and assemblies yourself. An assembly is an assembly of parts in other assemblies. That's 100% of it on the user interface site. Obviously to be clear we obviously want to do more but we can't we did what we can. So the from the we did run no dot come on get over there. Oh I can't share I can't get my screen to actually show it on that screen. You guys are seeing my screen yes. Yes. Okay I can't share my second screen bummer it won't it won't slide over. Great. Okay. Try to share the screen with Zoom itself. Wait a second I might get it. Here we go got it. Okay so real quickly the way we actually run is with the invoke script. However we created our own method type object sends you're sending to a method sending to an object rather. There's an account object so all objects in accounts you send it to the object you send the method you have in mind and the parameters for it. So for example I'm going to make an assembly and here's my object send here's the account of sending it to here's the make assembly method itself and then here's the arguments to it which would be I'm making an asset type making car assembly I'm giving it a part name a skew number certificate etc you make as many of you want and then you would actually have and you can create a vendor relationship by making multiple vendors so that was the idea if you're a vendor you would create yourself an account here and then you would be able to set your supply chain up and down by using simple set vendor set customer and so basically you walk up and down then you have a thing called I'll show at the bottom here a message called order create and apologies that it's a mess like this to the you know because doing the command line but that's what we're doing and you would send up the buyer supplier and so on okay real quickly the source code is all up on GitLab and it's public for all of the classes the our core system of course is at the moment proprietary at some day it'll be open source and so these are the classes you can see for the Bosch hackathon as we called it and you have an assembly asset and I just pulled up some of the methods and the files that can be the method so here's class vendor you would create an order it would receive a request you do a delivery make if you're a manufacturer you're going to make parts and assemblies and you set up your relationship then this just gives you a history of this gives you the picture of it so you can get this at any time in the same thing so here's a part same type of thing I create a part it's going to be an object and then it can add new parts and I can sell the parts and that's that's basically what you want to be able to do with it same thing with an assembly okay an assembly of course you'd be assembly of parts an assembly of other assemblies so you have these arrays where each part has a vendor account the object handles reference the objects is an all object-oriented environment by the way these are all dynamically loaded all of these classes are built independent of both the chain code which is what we call our class manager infrastructure and independent of hyperledger fabric itself the farther back in this this is how you do dynamic class loading let me see if I can find one real here you go and you literally just say load class you give it the name of the the path and the name to where it is and obviously these are done as file name but this could just usually be a url thanks sir the team alpha is on the call Aparna and Krishna whenever you are ready you're you'll get six minutes for presentation and three minutes for Q&A okay your time will start now so good morning to everyone present here uh we are here with an idea of innovative stock exchange solution using hyperledger fabric that is blockchain technology uh so we are team alpha we are a couple of members myself that is Aparna and one of my colleague Krishna Karnapurna so our problem statement lies under the domain of social impact that is financial empowerment especially so talking about the stock exchange system a stock exchange system is a exchange where stock brokers and traders can buy and sell the assets the assets can be in the form of equity stocks bonds or other securities which are present so many a trade basically in a stock exchange system is a in simple terms it can be termed as a transfer of stocks that is end users basically and many of the indices which are present till date they were you know recording all the transaction history in the form of paper so some of the indices have shifted from physical transfer of digital assets to digit from physical transfer to digital transfer and while shifting to this while digitizing themselves there has been many mile practices involved as we can see today in stock exchange a stock broker is a registered investment advisor who provides investment management services and who is responsible for execution of transactions in return for a commission so he takes the commission and he carries out all the transactions of his clients the limitations of the current stock exchange system what we have surveyed are that in today's market system all the transactions are done via stock brokers that the end users cannot perform the transactions directly they need the help of stock brokers who perform their transactions on their behalf and due to which this stock brokers took the advantage and many discrepancies and mile practices are faced by the end users some of these mile practices include overcharging of the brokerage rate they overcharge immensely on the end users or their clients and they do not share the complete data with the authorities so the authorities may include like DSE, NSE or any higher authority for the stock broker so these are also the cases available where customers are due to so in order to bring transparency we we have come up with a solution which uses blockchain technology so our solution to this is we will create a consortium where the central authority will be admin so these admin can be the authority like BSE, NSE as such and only the trusted brokers and the agencies of the organization will be added to the consortium and they will issue and we will issue them a private key and a certificate now all the end users that are the users like us who perform trade can use this brokerage broker agency and we will be added as a node on this blockchain now this transaction will be stored now whatever transactions will be performed will be stored on the shared ledger of the same channel that is if two people are sharing a same broker then they will be on the same channel and all the transactions will be stored on one ledger so using hyper ledger fabric we can create many such private channels each for individual broker and the different brokerage agencies so that the data will not be revealed to the other brokerage agencies so that there will be the competition which is there in the current system as well so our system will take care of it and the shared ledger will be accessed by central authority as well so that the central authority can keep a watch that there are no frauds occurring and they can figure out that where the data leak is coming from now the solution architecture will be explained by Krishnakant Good morning to all the viewers and I'll take can you be a little louder hello yeah yeah so I'll take yes yes come here as a part of my experience like we can use we can easily use crypto materials generated by our hyper ledger using crypto as digital assets because after all shares are digital assets which are transformed from one person to another person so from our proposed solution we are we are proposing that the we will create a consortium from from the top agencies as admin and by the brokers will be will be their nodes and with the organizations and the use of the broker will be their nodes so we'll keep a shared ledger can you be a little louder I I'm not able to hear you properly I don't know about the other members yeah sorry yeah you're better now yeah just better by the way it's a time stop so how much time is up sorry just give him give him an additional 30 seconds can you just wrap up real quickly yeah I'll just share my screen okay Apana can you just hold it out hello I'll show the demo of hyper ledger fabric which I've created locally I've created a demo for eight years yeah this is this is a hyper ledger network which which we have created in which this we're transferring amount awesome amount from John to Sam okay just a minute and we'll show we'll showing it okay so that has been invoked and you can uh she say it into the this is hyper ledger public extro ui uh the extro block has been created the block data can be seen the block data can be seen from here and this is a pre-hash and also the time stand can be seen so this is this is our demo for like as a transfer this is the basic principle what happens it's into the share market like in the stock exchange so thank you the next time would be hack bit team hack bit you're all on the call all of you are in the room now so quick instructions you will get six minutes for your presentation note that there will be hard stop exactly at six minutes you won't be allowed extra time and then there will be three minutes for Q&A Aishwarya whenever you are ready now we sit so as if it's screen visible now sir yes okay um then we'll be starting the um presentation you get exactly six minutes your time will start let me know when you won't start okay your time starts okay so good day everyone uh we are the group members um the team members Anu and Aishwarya Raj are the members of the group named hack bit and we will be presenting our uh topic direct marketing and agriculture overview what is dma a project which uses blockchain technology to avoid middlemen in farming sector and implement direct marketing between product producers and consumers which in turn will provide transparency security and benefit both farmers and consumers this will help farmers to avail more income and help consumers to get good quality products these are our countries abstract objectives hypothesis literature review design methodology work plan and finally conclusion abstract to create a supply chain management system for farmers using blockchain technology this helps to secure an easy availability of crops produced by farmers to the market it also ensures that farmers to do get the maximum profit from the crops produced without the use of middlemen in between we use hyperlature fabric as a platform to create the system ensuring that fruits produced are directly sold to the markets by the farmers objectives the primary objective is to create digital platform digital agricultural platform to connect farmers directly to the market so that crops produced is reached directly and sold out in the market for consumers we also ensure that with the elimination of middlemen farmers can sell their crops directly to the consumers and game fair prices how does supply chain of agricultural works farmers sell their crops to small traders who in turn sell their crops to larger traders and then to commissionation wholesalers retailers and finally in the hands of consumers middlemen intervention results in raising prices for the consumers boosting the production of crops requires high cost but we hardly get fair prices for the products from the middlemen the reason is that the real profit goes to the middlemen who buys the crops in low cost low cost and sells them at outrageous prices to consumers this attitude of middlemen has discouraged genuine investors getting into agriculture because of the marginal profit associated with it as the middlemen cut away the bulk of the profits thus the activists of middlemen seem to be a threat for food security our goal of this project is to eliminate the presence of middlemen thereby encouraging more farmers to produce more foods for the consumer at fair prices as you can see in the picture below the agriculture growth in India has been definitely decreased over the years from 1951 to 2016 and in the figure in the top right corner when compared to other countries like China and USA who are more science technology driven the production of crops such as wheat and paddy are much lesser in India who is more agricultural focused in the bottom right corner the similar situation happens where the agriculture per capita in India is much lower than the countries such as Thailand China South Korea and USA who are more technology driven here we formulated three main hypotenuse and the first one is supply chain planning process where manufacturer or supplier need a wider view of global and domestic supplies as critical inputs for effective planning and the sub hypothesis come under this category is first one is supply chain planning process and the second one is wider view of global and domestic supplies and third is critical inputs and fourth is effective supply chain planning and the next hypothesis next page next hypothesis existing practices of supply chain planning need more number of iterations to protect interest of buyers and sellers than existing in practice and the subjections come under this is first one is number of iterations which determines the consistency of the consistency of the project and the second one is interest of buyers and suppliers and third one is existing practices in matured product demand and supply and the last hypothesis roles of supply chain planners need to be strengthened with specialized skills mapping for effectiveness of companies next page for this project we perform literature review based on these five projects which first one is right T-foot I'll be 10x world and chain and blockchain next page so now I would like to talk about the formulation of design of the methodology we are going to use in this project the blockchain we are about to use is hyperlature sapphic tools and frameworks used are hyperlature sapphic SDK no JS jQuery and MySQL programming languages to be used are goal and for I think the chain code JavaScript php html css okay now I'll talk about the methodology we have an API where the user producer or consumer can log it or register if no account exists the user related information is stored in the MySQL database and the product related information is stored in the blockchain the producer is given option like check product app product etc whenever a new product is added a product ID or QR code is generated producers can tag the QR code to their product consumers are given option like check product we are providing the product ID or QR code we can receive the entire details at the next page the whole process is handled by the chain code which is written using goal and when user logs in the permissions are allowed accordingly as mentioned in the chain code producers and consumers can perform the task allowed to do that after the tasks are completed users can log out of the system our major goal is to develop a decentralized end-to-inverted application that stores the whereabouts of products at every flight club to the blockchain a consumer and consumers can easily scan products to our code and get complete information about the prevalence of that product as empowering consumers to only purchase authentic quality products team hack bit i think your time is up so probably you should have shown a demo if you have a demo probably you can play that demo in the background let jury start asking questions jury members block hunters are not on the call this would be alpha team number 13 you will get exactly six minutes for your presentation and the demo included make sure you complete that within six minutes there will be hard stop at the end of six minutes and three minutes followed for your q&a alpha all right your time will start so good morning today me team alpha from sainjith college of engineering are here to present on our ongoing project block fq a blockchain based food quality assurance the group members are myself president kumar thomas pjords sandra miran sabu and nithu well-serviced now next one okay now the food safety sand the food safety and sand authority of india has named kerala as one of the states that ensures food quality but even though when uh when compared to others in the list kerala still serves uh and hyzerinic and proteated foods and not only that people around the world are becoming more and more aware of the health and fitness they're being aware they're being cautious of what to eat and what not to eat so there should be a platform to validate the quality claims that are made by the hotels and also to monitor and ensure the food products next slide so coming to a proposed solution this is the architecture that we have come up with for block fq it mainly has three components the web interface the mobile application and an iot device the web the web acts as an integrated supply chain mechanism the iot device on the other hand is used to automate certain processes for the hotels the mobile application on the other hand is used to um um the mobile application on the other hand acts as an incentive mechanism for the hotels the blockchain here acts as an interface pretty much that's it um on the next slide so coming to the web interface um you can say that as i said earlier it mainly handles the supply chain and the transactions will be logged using the distributed ledger technology that is the blockchain and this web interface is used by the manufacturer the distributor and the hotel management and the hotel management can update the details as and when they consume into the block using this particular system also the iot device is connected with the website and that is including the rfid to retrieve these uh details at various terminals the website also acts as an inventory as an inventory management system for the hotel and they have to suppose the product is there for the hotel they have to update it every 24 hours as and when they consume it so there's also a smart contract put in the play that activates when there is a product that uh that is there in the hotel and it has exceeded itself life so uh when this happens it will be sent to a food regulatory authority and they can come and uh check uh check um in the hotel or taken out or something like do something important the webpage will be developed as a dapp then coming to the next one that is the mobile application okay the mobile application uh mainly acts as an inventory incentive mechanism for the hotels but also it allows the customers to give their reviews and they'll be being able to order food there's just an additional mechanism but main thing is that they'll be able to see the food ingredients from each hotel like from where their point of origin they can confirm this using the mobile application so thereby you can ensure the traceability and hotels um in the app will consist of all the hotels in the nearby area this is for the presentation right now and for the going for the demo right now and Thomas if we can't hear you with the demo yeah we can hear you go ahead yeah so uh this is the web interface that we have developed which is the primary interface to our supply chain so due to time constraints we were only able to create the web interface part and not the mobile application of supply chain so how this works is that there are mainly three entities here the manufacturer distributor and the hotel itself so upon clicking a manufacturer each the manufacturer distributor and the hotel will have a separate login page and upon logging in the hotel the manufacturer can see a list of products that he has that is the outer package details and he also has an additional option to add a package to his company and further than that upon clicking each product he will get a list of items which is present in this database that is each product's RFID its quantity the manufacturing date and the expected expiry date here also we have an option to add more items to this category now um that's it for the manufacturer part and what is to be the part we can have a login and here the distributor can enter the details regarding the product which they receive from the manufacturer it's RFID the product name the date upon which the distributor picked up the product or the date upon which he delivered the product and so these will also be stored into our database so uh this is all that we had I have created for now uh thank you next name is code code her thing team number 15 okay so code her thing team you will get exactly six minutes for your demo and presentation make sure you complete your demo your whatever you have covered for your showing to the jury panel within that time and then your three-minute timer for q and a will start okay so okay uh let's start good morning everyone I'm Shreya Suvarna and along with Nidhi Singh we are representing team code her thing as a part of geo family we are working on world's largest blockchain platform we would like to uh platform for regulating sms of 1.2 billion Indian mobile users here we would like to show you how blockchain can be used for public health so let's start with the problem statement as you all know that vaccine distribution against COVID-19 has started in India for few months now this is known to be the largest ever vaccine drive in the history of mankind even Interpol has reported that black market will be very large for these vaccines if counterfeiting of vaccines takes place it would result in various health issues on the consumer and since vaccines need cold storage without proper track and trace currently 6.5 percent COVID vaccines are getting wasted in India and these are not our hypothesis it is actually happening as you can see the facts here for all the problems we have come up with a solution and that is co-action and ai plus iot plus blockchain solution it will fill in all the gaps in the supply chain here we have used blockchain for creating transparency every participant can track and trace the supply chain and get to know the provenance of the vaccine also ai is being used for eliminating counterfeiting and ensure smart vaccine distribution and iot sensors will ensure that vaccines are transported in cold storage which will in turn minimize the wastage as you can see here the overall impact of co-vaccine on the various stages that is from the production to their last mile that is consumption by the consumer now let's move on to the solution architecture here we have three layers that is the front end back end and the blockchain layer the front end is built with angular and back end includes rest services written in goland the blockchain layer is being used here the hyper ledger sawtooth is being used for blockchain as this fits our use case due to its consensus algorithm and scalability as well as good performance so for interaction between the back end layer and the blockchain layer we have used sawtooth golang SDK having said that now let's move on to the demo yeah so there could be various other participants in the co-vaccine but for the sake of simplicity we would be showing it just for three major participants that is manufacturer distributor and retailer so let's get started with the manufacturer's login now we could create a package on behalf of manufacturer so the iot sensors would be used for capturing the temperature and humidity of the vaccines here we are providing a threshold value so if this value is being crossed then this iot sensors could send a signal in and we could know that the package is not being shipped or stored in the right conditions so let's submit the data so here we are getting a unique package identifier and then we land back to the home page these are all the package details which have been created by the manufacturer at the very top you could see the entry with which we just created so here the status of the package is created now let's move to the distributor's login for the demo purpose we have kept different web applications for each of the participants but in real life we would be integrating co-vaccine with existing system so let's login using a distributor so this is the page where the shipment details would be shown for a particular distributor so at the top we could see the same package id and let's go ahead and create a shipment so artificial intelligence would be used for stopping the counterfeiting of vaccines in the sense that we could scan the we could track the location from which scanning is done and if we find that scanning is being done for a particular vaccine from multiple places and very frequently then we could be assured that something is wrong with that vaccine QR code and counterfeiting is going on so that could also be eliminated so once we have filled the data from the distributor's end we get a pop-up saying that the shipment has been created and as we can see in the shipment details page the status earlier was created now it has changed to shipment initiated now let's move to the retailer's flow let's login with the retailer yeah so we can see at the very top the same package now for the demo purpose what retailer would have to do is he would to enter these data manually and acknowledge that he had received the package but in the real life this could be done through the QR code scanning so once QR code is scanned the details would be updated on the blockchain so let's get ahead and submit the details on behalf of retailer so this shipment has been received now let's move to sawtooth explorer yeah so we can see this is the payload which we just created and these are some of the other transactions so here we can see after retailer has received the package the status has been changed to receive so the journey of co-vaccine doesn't end here once retailer is having the package this could be sold out to customer and at that time the status would be changed to delivered so customer is having a vaccine now so he could scan the QR code which would be present at the end of the vaccine and he could track the provenance of the vaccine and he could also get to know at what conditions the vaccine was being shipped to him time's up okay so yeah that was the end of the demo the next team coming in would be electrust so team electrust you're all on the call so you get exactly six minutes for your presentation including demo so make sure you show important aspects of your presentation or the demo within that six minutes and you get three minutes for Q&A your Q&A will start immediately after your main presentation okay yeah yeah I'm ready thanks yeah you may start yeah okay thank you everyone for giving us this opportunity to present our solution at this event today I will be presenting my team's submission that is electrust but before that let's take a step back and double click on the problem statement so couple of weeks back you know we looked at the suggested problem statements in social impact category and were fascinated with the idea of increasing the elections integrity and voter rights protection using the technology when we look at the state of elections there are a lot of guidelines and procedures to ensure the integrity of elections and protecting voter rights yet it is very common news in major democracies across the globe where candidates are trying foul and doubting the integrity among the major challenges in the process we picked a few to solve like ensuring that the records are tamper proof prevent voter fraud and increase trust in elections various enterprises have come up with blockchain based solutions to conduct elections and those have been tried as well in different parts of the world but yet they rely on a governance body or a neutral third party which owns the solution or having a split of you know servers across you know you're in AWS and and you know similar so that is where in our solution is unique so we intend to prevent voter fraud by primarily using voter biometrics so everyone can cast their own ballot only second the solution uses hyper ledger fabric to provide transparency since any number of people even the candidates can create a node and share the ledger and thereby tamper proof records also we would be reporting the voter identification and ballots in encrypted format on the ledger but the main challenge here is that anyone with the node would also hold the ledger which contains the ballots casted and no one should be allowed to see who casted the ballot and for whom for this to happen what was required was a technology which could treat even the host as malicious and still guarantee the safety of data that is where confidential computing comes into picture so this confidential computing is also referred to as secure enclaves or trusted execution environments so secure enclaves require specific hardware which have a portion of the CPU reserved for hosting enclaves this reserved part is not accessible to any program or code running in the non reserved part of the same hardware so for the hackathon we have used Azure which provides Intel hardware compatible for hosting such secured and enclaves and are attested to be secured by Intel each enclave actually you know when it gets initialized it generates a key pair right for the asymmetric encryption it creates a public it shares the public key with everyone while the private key always remains within the enclave not shared even with the host or the owner of the program any data or code does residing within the enclave is secured also the Intel has a registry which checks and attests any enclave to be secured right so our process is a you know our solution is a full state process starts from voter registration purpose and candidate registration casting the ballots and telling the votes right so let me you know show this from in our demo so for the purpose of this you know presentation I've recorded the demo so here you know the process starts from capturing the voter biometrics during registration so encrypt so here we encrypt the biometrics using the asymmetric encryption and record them on blockchain having biometrics encrypted using enclave public key means no one other than the enclave can see or use them for any purpose other than you know what is intended right the next step would be having the voting purpose and candidates registered on blockchain in readable format so here we know we are doing that next is you know casting the ballot on the d-day right so like we just move on yeah so here we are going to cast the ballot so casting the ballot is a two step process where you know we validated the voter and its identity and finally issue a ballot token the validation ensures that the voter identity is matched against their biometrics on the ledger confirming that he is eligible to vote and second step is you know using that ballot token and voter choice and encrypting them in asymmetric encryption and recording them on blockchain here since the ballot is encrypted even anyone with access to ledger cannot ascertain the voter choice also the enclave keeps a list of voters who have been issued a ballot and had since voted so the last step would be counting the ballots so here you know the voter cast the vote and the last step here is casting the ballot. Munesh can you please switch on the machine I lost my electricity and you know so in the last step what would happen is the chain code will actually send stream all the ballots from the chain code would stream all the ballots from the ledger over to the enclave where enclave would decrypt them and start the counting and finally publish the results does this solution both of improved security increased transparency tamper proofing of records and trusted execution trusted election results so so overall you know this solution what it did was use hyper ledger fabric despite you know being a shared ledger it ensured that it is secure because all the records were on the ledger and were encrypted using that asymmetric encryption key generated you know shared by the secured enclave so all in all this solution will give you the required security level of trust transparency immutability time so and your elections that's protecting you know what the rights and election integrity thank you the next team would be Genesis so team Genesis you are on the call so Neil I think you are the only person from the team right and you get exactly six minute for your demo and presentation included your you will be short notified I mean you will be hard notified at the end of six minutes and you get three minutes for your Q&A hello everyone good morning good evening good night jury so I'm a single one one member team so I took up a plastic pollution as a major which is a major environmental concern right now as part of my use case and try to address it so I strongly believe that we do have a lot many environmental concerns or problems to be solved before we actually move on to major issues until unless we resolve or address these environmental concerns someday or the other we'll have to pay a happy price for what we are letting things go now so I want to see this solution for this plastic pollution from two perspectives one from a local strategy like for a city or for a municipality how to address it and if at all you want to take this solution globally how do you want to look at so it's it's like to start with I'll be starting it with a local strategy and go ahead with a global strategy so I named our team Genesis we all know that Genesis is the first block of any blockchain I want to be the first step in solving this big problem problem statement we all know it's been ages since we are looking at this problem the plastic pollution causing multi-dimensional damage for land water and air few alarming facts that the moment I looked at it I have been thinking about a solution since then so few things 500 billion single-use plastic bags which are being used every year and on average 15 minutes is the life cycle of a plastic bag which would the moment it goes on to earth it stays for a million 91% of the plastic so far created has not been recycled and the plastic will outnumber fish by 2050 and the major cause of cancer constituent benzene is part of plastic so victims every living being it's not just humans on this earth so what's the solution for it can we ban it I don't I don't say we can clearly ban it because of multiple reasons economical cheap alternative for plastic is yet to be found out so the only solution for now feasible solution to control this is to recycle have we not been doing this yes we have been doing this again since ages why are we not able to completely get this problem out let's look at the existing recycling mechanisms and challenges involved in it if you look at the fundamental flow of the recycling procedures the major challenge is the collection of plastic at the first instant itself right so the levels of plastic that is getting collected is very meager and we are not able to control the levels of new plastic that is coming into this world because the demand for the recycled plastic that is being supplied to the manufacturers one-time plastic product manufacturers is really not on par with the global demand so what are the challenges why are we not able to collect it properly at the source and why are we not being able to stop the plastic getting on to the landfills water and everything right culturally there are two things the whole world is looking at either you penalize people who are not socially concerned and discarding plastic like anything or in certain geographies we look at incentivizing socially responsible groups of people so though we have these two things as a solution why again are we not able to implement them properly the challenges in terms from a strategy standpoint penalties or incentives both work good but we do have certain implementation challenges right so we don't have a mechanism to efficiently execute either penalties or incentives right if you want to award a person who is responsible and discarding it has to be completely manual so far if you want to penalize how are we going to track who is doing what who is discarding what which which organization or which manufacturer is getting more plastic onto the earth so to address these two things I see the blockchain being a one-stop solution as of now in terms of a technology platform if you look at the reason being the value it programs with the net and the ease with which it lets us to exchange the value for something that we get into the system is great and and and it is efficient so at a high level the highlighted part of the portion of the whole plastic life cycle is what this solution is looking at majorly for now for the scope of this demo it's the plastic collection how do you efficiently collect plastic without getting that discarded to landfills so we we do have multiple stakeholders like ngo's transporters plastic collectors and segregators recyclers uh plastic product manufacturers resellers and at the core we do have people like rat pickers individual households apartment complexes generating this plastic so at a high level when you look at the blockchain as a solution why is it so unique right now I can take a blockchain solution for this issue right so the major issue involved here right now the crux of the strategy is to how to how to how to incentivize with the help of a ERC 20 token and how do you create a value to it there are two factors of which one it's a function of two things majorly when you look at locally it's the local plastic rate along with the offset that you need to add to it to make it look creative in terms of an exchange medium so I want to create this offset I want to add the value to this offset from the plastic product manufacturers right so the inherent value of plastic plus the offset that I want to put on the plastic manufacturers all together I want to make the collection or collection of this plastic lucrative in developing economies right because are the ones that you are completely forgetting to look at the next team would be sanguine team sanguine you both are on the call hi hello good morning good evening we are team sanguine so we propose our idea for specially tailored for chronically ill patients so our platform is called sanguine it's a decentralized matrimony social media platform inspired from today's social media platform but built specifically for terminally ill patients so this is what we'll be discussing today like what are the problem statements which we have and then possible technical solution and technical approach and followed by a demo and a Q&A so we have the problem faced by terminally ill patients specifically are like they have a social stigma attached to their health condition once anyone is diagnosed with any of the terminally ill diseases like HIV cancer or any such disease any such diseases they do have a kind of a social stigma they are rejected from a normal social life they are segregated in a way they feel depressed they have a very poor health tracking and also the medical facilities around the world are not up to the mark so they have very poor health tracking and it's even more difficult if someone wants to someone suffering with such diseases wants to get married finding a life partner for them who is medically compatible so that they can also lead a happy life and also their offspring also can be of good health so finding such a partner is a very difficult problem so these are some of the things which the current social media platform platforms or the matrimony science doesn't provide out of the box so to provide such a solution what we build is a centralized decentralized completely decentralized secure anonymous platform wherein all the users are trusted and verified then also we provide a better platform for health tracking and also provide an option wherein they can tokenize their health records and exchange with the research organizations or people who want their health records and also ensure that their records are safe and private so how do we build this particular thing there are three main features one is a user onboarding whenever any person who wants to onboard to the platform this is the onboarding process wherein a person would share is personal information is medical history and health records so this can be done in two ways one is let's say if the system or the person is not or platform where he is using may not be technically mature so you can just use a smartphone capture the photos and share it to the hospitals who are connected to our network so we use combination of hyper ledger indy and fabric for our solution wherein hyper ledger indy is used to mainly pseudonymize the user and provide zero knowledge proof as in when the request is made so if it is option one if there is a simple approach wherein there is a diet systems are not that mature you can use a simple paper based take an image and share it securely or else if it is if their system is already accurate if the hospital and the person who is enrolled is already in the system then they can use decentralized DIDs and claims and certificates for sharing it and sharing the records digitally and the hospital here would act as a checkpoint hospital or NGOs who are pre-authorized or they can validate the person's information the medical health records and see whether the person is actually suffering from this particular disease and needs some help or is someone who is looking for based on the verification if the verification is success then there would be a pseudonymous ID which would be created followed by a document vault which would be specifically assigned to a particular person to store track is health records and also a digital wallet followed by an approval to join the community so here what we do is let's say a person is group we group them based on terminally the disease which they are suffering from let's say cancer belongs to one particular channel people suffering from HIV belongs to a separate channel so that way so basically this is what a profile would look like so once a user is verified you'll have a wallet assigned to him then there would be a pseudonymous ID there would be no way anyone can get their personal record and this is the hospital in which they are working on and the different records whatever the personal information we have along with tracking or usage of their health records where exactly they have used this is how the person is onboarded once a person is onboarded we have built a machine learning algorithm a very basic decision tree based algorithm specifically for people suffering from different stages let's say if they're suffering from HIV they have different stages right stage one stage two stage three so based on their blood count and the current medication we built a compatibility score with their health record so a person sends a connect or if we check the other person who has shown interest for getting married so we send a connect then both can share their medical records to a medical professional he can get the records quickly from the system which is all digitized by this time and then he can view all the health records and recommend whether they can proceed with their wedding or if they want to have some prior tests or medications he can give the recommendation based on which both the people can take an informed decision so this is how a compatibility score works which is a combination of machine learning as well as blockchain where in the data is shared and trusted in persons are in the loop that is what we try to build here this is what it would look like wherein a person they would get a very basic information none of the until they are connected and accepted they don't get a much in detailed information wherein they can send for a reject accept or get married so this compatibility score is based on a machine learning model which will check their health records and give the compatibility score and they can also go for a secondary medical opinion before taking the final call time and the last part is the secure information exchange wherein they can upload medical records here we have built in our own specialized algorithm which is based on AFGH we use AFGH and in the just the way how blockchain works a cryptic curve algorithm wherein all records are dynamically or encrypted using different keys so even if a person a private key or a public key of a person is shared only one record might be accessed but each time we create a new ID then we have a separate key management agent for storing the records and retrieving it so this is what a record would look like let's say a hospital national earth research wants their monthly response to a particular tablet so the person will have complete access on whether he can approve or reject in this case once a record is approved the hospital can view a particular record so here each hospital will have their health record along with the access key wherein they can view this access key to download the health record decrypt it and view it so these are the three main features of our platform wherein a person can get an history of which health record was added when and a complete consent given so this was team sanghway okay thank you thanks for the time thank you the next team would be team ionites i'm letting team ionites into the call i would like to thank for giving us this opportunity to present here ourself i'll not take much time on this but a big thanks to hyperlitter india chapter for organizing this event title we gave to our submission is blockchain and public health reimagine credential verification and trustless access because we are present we are presenting a use case where a solution where it can be used in various use cases where data needs to be protected and used wisely as per users consent so there are um we are team ionites i have my um now a teammate sirenjit and amit padmini with me and myself on kitha so the problem statement um here now we are showcasing two um we are showcasing a solution for two of the problem statements that were given first is to prove vaccination status and the other one is opening up the workspaces schools colleges in a safer manner for children and everyone so um as they say says a coin has two sides so as with the digital era it gave us an enormous opportunities facilities to share get and monetize our information helps in being connected with each other everything in few clicks and whatnot but there is a darker side of it that caused facebook data breach 2019 adha data breach 2018 maria data breach mgm zoom big basket and whatnot uh in recent in february 2021 2.3 billion record uh are breached mobi quick data has leaked uh covid 19 test results of indian patients are leaked online so uh hence users privacy is on stake in every domain we take in every manner the data is there out on the internet so these are the problem statements these are the problems pinpoints that we have with the technology that the way we work we the way we store our data so how to enable security and privacy preserving access in this covid era since health records are very sensitive uh and um very sensitive and uh information a person can have so um like identity is the most important yet vulnerable in today's world that's that's least i can say so the proposed solution for the state the problems the statements that i have given uh the solution that we are proposing uh comes with the power of blockchain backed by cryptography w3c standards for verifiable credential and it is leveraging hyper ledger india as a blockchain and iris uh hyper ledger iris as protocols so the so the solution we propose uh is where every credential a user hold can be issued as a verifiable credential or can be converted to a verifiable credential so verifiable credential that comes with a security by default they are by design by design secure and put user in driver's seat of its data we called is at call it as self sovereign identity where it is self managed and self organized uh we took the solution to the next level and we integrated uh iot device with hyper ledger iris agents so we gave iot devices a capability to uh play with and to use verifiable credential as in when needed uh this is a solution which is applicable to several industries but we are presenting as the public record or the health record management one so this is the proposed solution we have next come up is the solution and solution architecture of our system so there are multiple components of the system we sorry so we are using all the open source uh hyper ledger projects and open source platforms uh we are using credible platform and adea mobile app and a raspberry pi you can see if all of them in the um in the architecture that i have shown so the credible platform it is built on top of open source hyper ledger projects that is india iris and ursa and it is built focused uh on building a decentralized identity system where you can exchange you can use verifiable credentials adea mobile app is built for the holders to store the credentials securely and with all the w3c standards and the standards that are laid down in the industry for using verifiable credentials and uh this mobile app gives a capability to present out the proof as and when needed out of the credentials that user is having then the next is raspberry pi that is the one feature that is cherry on the cake of the solution uh it is a low-cost credit card sized single board computer uh and we have loaded this with hyper ledger aris agent that gives it as a capability to cryptographically verify the proof generated by the holder so it has all the facilities to issue as well to issue a credential or to verify but we are using it for the verification purpose so uh the digital handles that we will talk in the in the demo are going forward uh on the smart doors should be backed by the raspberry pi agents so this is what the architecture of the solution is so credible platform is all on cloud environment so we are using google cloud environment for this every application all the systems which which will be on the consumer side they have their applications running on the native systems and they will have their cloud agents on in the google cloud all the agents will talk to the secure blockchain agent that is hyper leisurely and it will talk to the mobile wallet we are running out of time your time sorry yeah so i would like um uh sigh to take up the solution uh the benefits of this uh the solution that we have proposed okay so uh in this demo as we discussed we have uh three three main uh issuer and verifier we can say this is simply the issue the credential so main use case we are demonstrating is we are converting our national id aadhar card indian national id aadhar card into the verifiable credential so in this case user first will download this offline aadhar card from from the ui ui di website so simply they will enter the otp which they received in mobile phone and also set the some passcode to access this file something like that so so once when once the otp is verified simply we can user can upload this zip file uh into the mobile application we are checking the data by verifying the passcode and mobile number which enter so once aadhar we have in our hand then we are we are verified by by verifying the passcode and the mobile number which enter by the user and the user simply applied apply for the for the aadhar card as we see so simply currently we are applied we have one issuer name is bank of future so simply they will they will issue this credential so holder is requested to aadhar vcn now we are going to issue this pc to the to the holders so once once the offer is sent successfully to the holder holder will simply accept this offer and store this this digital credential in his wallet so whenever the need simply they can they can verify this data so if i go forward first because we are running late of time so now now in the case that we have we have our we have our covid credential vaccination credential so simply again in the covid credential generally we are we are giving the all country are giving the qr code so qr code has contained some data so again we are converting this qr code into this vaccination data into the vc so by scanning the qr code we user will get the data and again apply for the for the digital vc so again the medilabs care is issuer for the for the vaccination record so here ajay nagar is requesting for the credential but before the issuing the vaccination credential for example now medilabs wants to verify his aadhar record as well so simply they just generate the proof request over the presentation section so simply they select the credential which they wants to verify apart from there is also yeah so basically the use case we are demonstrating here is a is converting the national aadhar into the verifiable credential so there's the use case that we have another credential there is a vaccination record so again we are converting this this vaccination certificate into the verifiable vc and apart from we have added the iot layer over over the over over our solution so where we have have iot door handle kind of things so simply they yeah it's hosted by credibility itself so we are using this one yeah so blockster labs which from which we are presenting it has developed credible and other platform both and we are using the hosted solution so again we have received the proof request on on the user's wallet so simply i will so user will send his aadhar record for the verification so once verification is completed so medilabs will issue this requested credential to the holder's wallet so holders have an hour an hour two credential there in his wallet so now again as we discuss we have use case that once the code will go on and we want to secure entry to the employment so that's why we add one another layer over there so blockster lab is a is employment where user is doing his job so simply let's move forward so again blockster lab will issue one more credential it's the employment vc and when when user wants to access the office door at the time they need to present this kind of credential so simply we are again issue one more credential to to the to the user so in mobile we have also received the employment card as well so we store this credential in our wallet so right now we have two credentials so now if i go to the blockster office and i its iot door is present and now i want to provide the vc that i have a national id card i have a covid vaccination i done with the covid vaccination and i have a valid employment id to enter into the office so simply when i go to the office simply i will scan the qr code which they have on a door simply will receive the proof request so i will the requested data is a vaccination certificate vaccination name from vaccination certificate name from employment card and roll from again employment card so simply i will present this data from my wallet and once the data is verified we can see there is a green signal is given that i have valid credential to access the door so access will be granted to me now in future when when i resign the job from the blockster lab and now blockster labs want to revoke my credentials so simply they can easily revoke this credential so they simply revoke the my employment id because they issued the credential to me so here if i go to the blockster lab office and i scan the qr code again so again user will receive the proof request to present the credential so yeah again when i send the proof from my wallet and it says that access denied because the credential employment credential issued by which issued by the blockster later on they revoke the credential so user cannot able to access access this door no more so this is the use case that we have we have built over there so if we're talking about the future enhancement so this kind of solution can be used by the hotel or or other hospitality platform like like all your rooms and also where user when user can simply receive the access credential of that door something like and also provide the national id as a verification even in this case if we can also use
