Smart Cities: Leveraging Decentralized Technologies for a Sustainable Future / Lorenzo Nardiello

Transcript

we can go it's okay okay thanks for joining me today um I'm going to talk about the link between smart cities and blockchain so the world is moving fast and the future is urbanized in 2050 70 of the population the world population will live in cities and in the next seven years we will see 10 more mega cities the future is urban and blockchain can be a solution to bring traceability security

decentralization and transparency all of these citizen will also bring a huge amount of data thanks to Connected cars iot sensors environment sensors and their own utility usages SO gas electric and and water conception foreign two questions how can we leverage this data and how can blockchain be a central actor so in my example today in my presentation we will explore three

things the first one is decentralized identity which is useful to identify citizens and to avoid malicious actors and also useful to create a segmentation so you want to know who are your citizens where they live and where are they exactly who are they exactly sorry you also need a decentralized data Marketplace in order for them to keep control on their data to get more transparency and together them around one platform and as we all know to motivate people you also you also need an incentive for

each of them so let's explore the the ID so here I took an example of Hallis um Hallis needs to be onboarded to create a self-identity for that she will use a smart wallet so ERC 4337 standard so she can enjoy social logins and Recovery to make it way more smooth than getting a private key dealing with it and you all know the issues with all of the things the second step for Hallis so now that

she has this smart wallet she can create a neoness so Alice dot paris1 because thanks to the Z gay proof the city proved that she uploaded we know that she's living in Paris First District we also know that she is more than 18 years old that she owns a wearable and that she also owns a car so all of this is composing the identity of Alice and it's part of the hyper personalization you can get hyper personalization using meta nft so a meta nft is composed of several

layers and each of these layers is representing an information of course it's a solvent token so it cannot be transferable the identity of Alice belongs to Alice only so now that we know uh who is Halle's what she owns she can start to share her data so here is the decentralized data Marketplace Hallis on the left side is sharing your data into data sets so she can provide information for example the city noises when she's working in our city her

electric consumption or her cards data for example and even or else data because it can be very interesting for a city to know if there is a pattern concerning the the else of the citizens of course she has the full ownership of this data she can revoke access anytime and she can get control and she can also get a full transparency where is our data where it is going you can also Imagine Community data set so plenty of citizens from Paris first districts for example can provide the same information on a specific topic

on the other side you have the city managers that will analyze this data they can create restricted data sets so for example getting information about cars from people living in Paris First District it is possible thanks to hyper personalization you can also use confidential Computing and sgx Intel enclaves to deal with sensitive data so for example else data you can do it in a perfect privacy way in exchange of this data the city managers will give to Alice a reputation

so this reputation is part of the meta nft of Alice it's part of her identity it's a layer into the meta nft so now how can we incentivize Alice to do this job who knows what this is nobody okay this is a coin from ancient Greece it's called um a Pericles story uh used this coin to do what he called mistos

so mistos was a way to incentivize people the poorest people of the city to make them participate into the city life so if they were voting if they were debating if they were saying if something was good or not they were paid for that so this is a way to incentivize people the financial one and this was probably the first ever reward token existing but we can imagine several other things so depending of your reputation score and depending on how you're involved in your city life

you can of course enjoy Financial one like infrastructure discount so if you are participating and you own a car because you know we know it now thanks to um thanks to the meta nft then the city can reward you by giving you a discount for parking or can give you discount for public transportation for example and the more you're participating the more your score is important you can get an IO power vot for a calorie referendum so let's say that your District decides to change the bench in a park it will cost a lot of money of course so they are asking citizen what are they thinking about it

well as an involved citizen you can have more power vote on this decision because you want your City to be better and better and you showed it then you can access to strategic position such as Town Hall member for example and even a national representant so what are the advantages of all of these things well it increased the citizens engagement so people are more involved of course with the incentives but also thanks to the impact they can have on their City the city is continuously improved and you can highlight issues so politics

cannot be blind in front of issues if you have 10 000 of citizens feeding a data set showing that something is wrong they cannot be blind it also increased transparency about data you know where is your data how is it used and who is using it and something very interesting this is the last point and this is where we can change things you can have a new kind of politics instead of getting politics based on how wealthy they are who they know which powerful party is pushing them you can have politics that have to prove that they were engaged in their City

before being engaged in politics so it can be for example a condition to access to an election if you don't have Nino's hygieners repetition score you cannot go to the election and like this you can have only people that care about the city and you avoid all the people that are just opportunistic or that are also corrupted so the good news is that it's already possible so I'm working Italian's blog and we are building two interesting things the first one is

the decentralized identity The Meta nft technology so we are able to create these layers that can include any ZK proof inside on the other side we also have data tunnel which is a way to share this data and we can also we are able to do a community data set so if you want to know more about this project just visit it that's it for me today um if you want to learn more about it you can check the alliance block Telegram in Live or you can reach me

also uh personally thank you very much if you have any questions [Applause] we're good uh any questions so my question would be this is a little bit similar to the

social scores that are developed in China um so are you using ZK proofs and how do you differentiate this how you avoid possibly negative aspects that could be caused by this in cities so the difference between what sorry the social story in China ah the thing is here you can anonymize the data also so this is also a component I didn't show it but you can anonymize it so the city can only access to a generic data and the reward is automatic but it's not about um

doing some like having the police behind you and surveillance it's more about participating if you want it that's also very important we don't take your data you participate and you allow to share this kind of data or not so you have the full control uh at the end of the day and if you consider that this is not um that that is not good for you and not good for uh your city or it's not aligned with what you think then you can just stop to sharing them for the incentives do you think it is a good idea to involve for example the

business retails in the cities like you know I would be getting a discount from the Starbucks or McDonald's and so on so whatever yeah uh you mean uh discount for enjoying retail like like the business business would actually like to like to give me some reward for higher reputation in the city uh so they might be interested in like rewarding those people yeah it can be interesting too I think it's a good way also to involve them uh in this I was very focused more on on citizens but of course you can open it to also retail of course foreign

thank you very much thank you for your attention thank you [Applause] [Music] thank you
