2024 ETHTaipei Demo Day - Team 9: ZicretPair

[Music] hi I little friend and uh today I will give a little introduction about theare and currently work at an as andet foring con Solutions and the not proof and if you have any questions or just want to discuss with me uh you can find my content Bel the slide and uh the is the pry parent match and just like and the key features uh the first key features is decentralize our potential and uh liquid pair will upload any user uh personal information and uh requ requestment and approvement and sharing for on the blockchain and it is Power by uh Z scine and and uh the compare uh you integrate the this for ver verification and uh the other users Andro you are a h uh you are a true human and uh the third key features is zpp to token and uh in the future you may be a part ofex St and it will be unty L we user for the their SC have bonus and it is re with the Port verification and next two Tex St is PR intersection and E and these two t help uh L PA can uh help user exchange their uh personal information in inry and without uh reveal their true uh information and uh for the live demo here is some three and the first is uh the PA Bo it just a website and let user complete all operation about PA like user want to construct a uh local profile or inut plan and go online and send the approve uh send a uh PIR request to anyone and approve the uh pay request or just uh exchange the ecd information and next is go just deploy your local profile and uh send the inity information to the blockchain and let other see you your online and next is a comp Pro and it's just a uh pry identity verification application and it will produce a human score and store it in a smart contract and you can request the getco passort smart contract to know uh this address is a real human not or okay and next is a privacy set conversation and it can help the two users are just deploy their encrypted information and without reveal it and they can culate the mat match score uh between between these two user and next is an eliptic curve uh DP Helman and uh in the blockchain neor uh uh IM Nots very Superior to exchange the personal information because uh it is transparent and everyone can see your maybe Twitter or name or Instagram hand if you publish into but uh in zare uh we use the and you can in leas transparent Channel and you can exchange your encrypt exchange your s text and decrypt with the sharing key and in the uh in the uh th pair here are some data formats and the first user need to construct their local profile in the par like uh you have your public your private like your Twitter is Moly 1 2 34 your name is mly and um you match like who you are and where you you come from and what is your interest and next is your M request like who you want to pair with like you want to find a male and you don't care his nation and Tom and you hope he is a 30 years old man and then uh you can group it in the theare board and you can trigger the GOI function to the the Contra and deploy this information into a contract and next the other and you you can VCH Hors online users and if you find someone match score uh calculated by the PSI uh match uh uh satisfy your expectation you can send a request to him uh like uh in this example uh mly send a request to alred and In This Moment Molly doesn't know of this address is alred and then uh alred uh receive the P request uh he can send a pair Improvement to the mly on the blockchain and all all these operations are transition on the L and then if Molly receive the PA improvment Molly every can exchange the sharing inform and uh by culate the public key uh they exchange to get the sharing key and improve the uh personal information and exchange and then they can use the sharing key to decrypt the C text to get each other personal information like or your your name is and the uh $200 is and so okay the D TR uh for the demo I use the net and deploy the deploy the Contra and use two uh Local Host to pretend uh two users uh uh represent this page is B and Poli address is z X7 and this website is Al it address is 0x4 and the first step in the the um preprocessing uh you should uh turn your St and BR function on uh Deco pass F but we uh ignore in this part and uh the first step is online you should construct your local profile in the uh in the secare board and in plan and you can get the impr information and in this in this T version I use the just just a catch oh okay you can just get the function and you can C the go online and next request pair you can see others and the third the thir SP you can uh approve someone send a request to you and next you can exchange your info by the is key and then you can reveal the others uh personal inut in this uh world and I pass thetics and in conclusion uh there is some there are some security cons consideration like uh anyone can replace the others in import to the high score or uh ex uh for the to the privacy of PSI so we want to use the uh we want to achieve the truly privacy matching which integrate thear proof orphic encryption and okay guess my [Applause] thanks right uh any questions uh was yeah thank you thank thanks your presentation um I have one question the so there was a human score part of that probably that's very important to get rid of all the kind of f or some like you know low quality profile like by using that Technologies right and then you have a jpp tokens that gives kind of some kind of bonus for that it's kind of kind of training of relationship between like you know actual Humanity versus you know because you know anyone can buy the J tokens and then kind increase the human for in the case yeah uh uh in uh in my design uh the dpb token is uh is mean to a sign server so it is on transferable nft token in the S servers correlated uh smart cont so uh the user can transfer the DPP token to uh to others and if he or she want to meet the DPP token uh he and she should send the mat uh much successfully information to our signing server to me this token any other questions no thank you
