 Good afternoon, everyone. Just waiting for the slides to come up. My name is John Garretts. I'm co-founder and CEO of Okan Innovations, formerly Project Okan. And I just want to start off by saying how excited, and I think I speak for the rest of our team, when I say how excited we are to be here in Cancun at DevCon 3 on this stage, speaking to you. And when I say you, I mean the community that we've all been a part of for a number of years now. And we're really excited to tell you kind of the story of Okan is what I'm going to start with over the last year. And then I'm going to hand it over to Lexi. He's going to take you through a few of the technologies that we've been building out, and then we're going to wrap it up with a video. So again, my name is John Garretts. I've been in the space since about 2014, very early on in Ethereum years. One of the first projects I worked on, Airlock, was on Proof of Concept 3. So very, very early years. From there, I was able to secure a developers grant, a dev grant from the Ethereum Foundation for Eth Embedded, which was essentially taking the Ethereum client and porting it to ARM-based resource constrained devices. And that allowed me to start to build relationships in the community, and many of those relationships are now my co-founders with Okan Innovations. This is our team. We have a fantastic team. I'm so proud of what we've been able to do in a very short amount of time. Many of you are familiar with Hudson Jamison, but we also have Lainey Fisher, James Johnson, Lex and Daniel is the most recent addition. Shout out to Eth Lance. Daniel was a recent hire. We went through the process of Eth Lance. And so shout out to someone else in the community that we've used their tools and has worked out very well for us. So this is kind of the story of Okan. About a year ago today, the majority of us knew each other, but we hadn't really worked together. And so we got together about this time last year to enter into a couple hackathons. The kind of result of that was a judge's win with a hack ether camp. And then from there, we built on to a first place finish in the Dubai virtual blockchain gov hack. And first place was $100,000, all expenses paid trip to Dubai. And our project there was a proof of concept that we refer to as Tesla and toll booth. And what we were able to do is install an Ethereum client in a Tesla and install an Ethereum client in a mock toll booth to demonstrate the true machine to machine transactions with no human involvement. That gave us some traction from one of our partners initially Toyota Research Institute, which we moved on to build out another proof of concept for peer-to-peer car sharing. And that was something that we debuted in May at consensus 2017. And essentially what we were able to do is install an Ethereum client in a car, connect that to a FOB and through a series of ESCRO smart contracts, rent out or short-term lease that vehicle. And this is all these proof of concepts that I'm speaking to are functional proof of concepts. These are things that we have built out that are up and running, not in a production environment, but up and running nonetheless. From there, we've been able to be involved in a number of other projects, I guess, MIT Media Lab. We're really working with Toyota Research Institute to start to facilitate some kind of an open blockchain mobility ecosystem. And so in the past, we've invited other automotive manufacturers to come to the table, and we've been at least successful in starting that conversation. We're based out of Dallas, Texas, so we have a strong relationship with a lot of the universities in that area as well. We're involved in an open data initiative with the Texas Department of Transportation, or TXDOT. And we're also talking to a few toll road authorities, both in the U.S. and abroad. We're a member of the Trusted IoT Alliance. This is a, we're very excited to be a part of this group. There's a lot of active members in the Trusted IoT Alliance. We're still kind of a small group, but growing fast. And ourselves, we've been able to contribute MQTTT, which Lex will talk about in a little more detail shortly. And if you're out there and you're working on IoT and blockchain and you're interested in becoming a member, please go to TrustedIoT.org, Trusted-IoT.org, and check it out, sign up, and we'd love to have you on board and kind of learn more about your technologies. So it's now my pleasure to introduce Lex, Shuang Liang. Lex is our CTO, and he has some prior experience. Lex and I met in Guelph, Ontario, Canada, which is close to my hometown. And we kept in touch after that initial connection. Lex did some IoT internship work for Aeros Industries, which is now Monax, and joined the team just prior to the Dubai event. So please give Lex a round of applause. Thanks, Shuang. So, good afternoon, everybody. So I'm Shuang. In Chinese, Liang Shuang, you can call me Lex. And I got my master degree in computer science at Temple University in Philadelphia. So I'm glad to be here to introduce some of the technologies that we are working on recently. So, yeah. The first one I want to introduce is the MQTT Trusted and the second one is the MicroDep. And also we have a hardware security model we are working actively with to build some secure hardware for the IoT platform. Yeah, MQTT Trusted is a trusted version of MQTT. So it's based on the MQTT library and the Ethereum library. MQTT is a very lightweight pop-up sub based the motion-to-motion communication protocol is very popular for IoT applications. It's designed for very low-band-wise communication for some sensors or telemetry devices. And the feature we want to bring in to this motion-to-motion communication is from Ethereum global likely unlimited identity system and also it's trusted without the centralized control. And we can use the built-in ECDSA algorithm to get the signature of the messages and embody the signature to send to the receiver. So here is the flow. From the center side, it puts the plain message and the MQTT library will build some package like this. It has a from and to field which is based on the Ethereum address. And we put the timestamp as the profile date to put some constraint of the appellation of the message. Also the date load and the sequence number. And after that we'll use either the primary key of the Ethereum or hardware security model to send the message and put the signature into that message. And as the receiver said, it first can recover the address of the sender based on some Web3 library or Ethereum library and it can check the permission of the sender from the smart contract. Also, we can do proof of a provenance of the data or access control based on the identity of the sender. So there are some issues we want to solve from this library is interoperability. There are some problem surfers. The first one is signature can be messed up if the sender and the receiver are connected the sender and the receiver use different libraries to send and recover the message. And the second issue is this part of the property is another standard. So we want to probably standardize this machine to machine communication scheme. So it will be either for your fridge or you will talk with the microwave or talk with your car. So they are all compatible with each other. So because of these issues we want to collaborate with the community with trust to the IoT alliance to build some standard for the machine to machine communication also build some semantic on top of the Ethereum blockchain and this protocol. So the next one we want to introduce is the microdap. So you can see from name is small worry of the decentralized application. We use Raspberry Pi for our hardware platform but we can also put our stack to other embedded system like BigoBone and other embedded device. So we use Ethereum Lite Clan for the smart contract and IPFS for the data storage and the MQTT library to support machine to machine communication. So this is an example of the architecture we are working on from the top layer is the decentralized application for the then for IoT use case and we have three components. First one is decentralized data storage API and trust to machine to machine communication interface to the application and also the smart contract. So in the middle layer we have IPFS but you can actually plug in other decentralized data storage libraries like the swarm and the MQTT, the Ethereum blockchain actually we are trying to build to support other blockchain like hyperlider quorum and under the lowest layer is the hardware abstraction layer we can support center data and hardware secure model as IoT wallet and here is an example of the microdip service to interact with user using the mobile app or web app so here the boss has access to the Ethereum blockchain and IPFS for data storage but it's not like pure centralized infrastructure we still need some like server to offload the computing task from the embedded device to the servers here we use MQTT broker on the server side also we need some server to offload the Ethereum gateway and the IPFS gateway to support the contract device so here is a real world example we build with Toyota for the Decentralized Cache application so you can see it's not like a traditional server based design paradigm it's really like peer to peer all of the cars have our microdip services running and they can communicate with each other through the MQTT machine to machine communication and access to the smart contract so we have the video to show the real app and the user experience later on I'll go very quickly for the hardware secure model we build this hardware secure model with some requirements we want to for the IoT and production application first one is we want temporal proof to prevent the attacker like physically attack the device and we want very secure case storage and revoke the key when we detect some attack intention also we want it to be blockchain compatible like we can send using the hardware secure model and using this signature compatible with Web3 library or other Ethereum libraries so here is our current accomplishments for the hardware secure model we can send offline transactions and we can send personalized transactions also we have this Node.js library to access the functions in the hardware secure model so there are still ongoing work we actively develop like here we are developing the physical temporal detection with collaboration with some hardware companies we are building this secure case storage based on the secure elements these all are like ongoing projects we are actively working on and we are like community driven and like to talk with developers if you have questions you can go to the website and state you and we may have more release like the MQTT thank you thank you everyone so as Lex alluded to we have been in as much work as Lex has done on our back end systems we have really been focused from the get go on the front end and really making sure that there is a good user experience in fact some of this was born out of necessity for us to keep that user experience at a level that we are comfortable with so we are just going to play a quick video for you now this was first launched at Monday 2020 last week in conjunction with Toyota Research Institute and that kind of gives you our vision of the mobility future hello from Okan Innovations we are excited to show you what we have been working on with Toyota Research Institute earlier this year we debuted our proof of concept blockchain enabled peer to peer car lease application at Consensus in New York this application allowed consumers to lease a vehicle from a car owner using a smart contract on the Ethereum blockchain file storage on IPFS in a mobile application to lease and control access to the vehicle prior to our car lease model we developed a blockchain powered automated toll road system with connected cars this project won us the top honors among the entire world at the UAE International Blockchain Hackathon these applications allow for instantaneous remittance between the transacting parties they do this without the need for payment processors by using logic coded to a smart contract the hyper secure blockchain based IoT controls at a level of security not currently available on the consumer market all while reducing or eliminating the need for server infrastructure Okan Innovations wants to give you a glimpse into the mobility future we envision we use the blockchain for application logic and data storage replacing traditional server infrastructure here we use the blockchain to store vehicle identity along with GPS now we add road and mapping data and allow trusted entities to update this decentralized data layer smart road sensors can also feed this database this allows for a complete view of all vehicles and infrastructure with current construction and traffic conditions while allowing third party applications to be built on top of this data lets amend that vehicle data for lease or ride sharing services this now allows consumer mobile apps for ride sharing or leasing using this blockchain services layer in a ride share or lease transaction things get very interesting in technology, instant value transfer and micro transactions are now possible within one smart contract transaction is instant remittance to several parties including the vehicle owner and driver, insurance provider toll road authority and road tax entity why is this valuable? the automobile owner and driver received guaranteed and instantaneous payment of funds micro insurance policies for each ride or lease transaction can be paid to an escrow contract then remitted to the insurance provider once the ride is complete with the balance of that escrow going to the rider or lessee we can use an escrow contract for autonomous toll payments and even eliminate toll gates from the toll road infrastructure as we can prove the location of the vehicle using GPS we can even have smart toll road infrastructure where roads are only charged during peak hours as consumer behavior moves away from purchasing fuel and favoring pay-per-ride mobility over vehicle ownership road and infrastructure authorities will face a shortfall of tax revenue that currently funds the construction and maintenance of roads included in the mobility transaction is a usage-based tax to replace this lost revenue even short trips where a fraction of a penny is needed for taxation all of these parties receive the benefits of instantaneous remittance all included in a single transaction user experience all without the need for payment processing intermediaries let's go further with this blockchain platform in this driving world we get to go beyond rider mobility into other applications solar energy production is highest when the sun is shining the most that's typically in the middle of the day energy demand typically spikes in the morning and then again in the evening time that solar energy production is weakest during low mobility demand times automated vehicles can store solar energy during peak production times then deliver that energy when and where it is needed also, since we have the automobiles equipped on activity, we can provide a self-healing mesh network across large areas as well as a partitioned consumer wifi service all while the vehicles receive microtransaction reimbursements for sharing their internet connection thank you for your time and we hope you enjoyed our version of the blockchain powered vehicle future for more information please
