Building the Communication layer for Web3.0 - Harsh Rajat

everyone so let me just start with the slide yep seems cool so yeah hey everyone i'm harsh project lead of ethereum push notification service uh we are here to talk about why uh the communication layer for web3 is really really important so let's dive right into it so of course we always want to start with some good vibes which is why we are not full screen and this is not a good vibe studio just give me a second all right here we go awesome went exactly as planned all right uh so guys uh why uh communication layer for web3 is important or what are we missing in uh webtree uh well it's communication uh just think about it uh what is web 2 apps uh what do web 2 apps have that web 3 app doesn't uh well they have communication from services uh we usually get up in the morning we pick our phone and we are seeing uh notifications from everything that we do whether it's email uh whether it's any delivery which we have done through amazon whether it's our bank account or whether it's uh something social everything comes to our screen and from there we take it forward uh even something like something as personal as when we are chatting with someone it's coming from notifications we are not going to whatsapp or signal or telegram we are just waiting for notifications to come to them and not many people realize but uh even when we are doing facetime video uh voila that's notifications just that the operating system is interpreting is differently so yeah that's web 2.0 uh let's go to web 3.0 uh and you'll see this communication lagging and this communication uh not being there uh putting us through so much terrible ux and ui uh it results in a critical info drop let's say you're building the next uh d5 protocol uh again how do you communicate with your users that a wallet address uh communication layer is not built and therefore you cannot and that causes a huge problem uh your loans are liquidated and you as a user you don't get to know about it when you go to governance or dowse you're building the next dow again how do you communicate to users that your proposals are there and they need to vote on it well the fact is that people right now do it through twitter and discord and maybe just maybe it will reach you but if you're involved in 10 hours or so it will never happen uh and then you know you take this concept further you take it to nfts you take it to metaverse again you have to realize like unless you as a web 3 user are able to communicate with the other web 3 user the communication will never be as useful and as uh usable as a web 2 platform well of course that's the problem the solution it's definitely us we fixed that for web3 uh what we did was we introduced a new communication primitive for web 3.0 uh and by that we mean uh we created a decentralized communication protocol using which any dap any smart contract or any backend services can send communication starting with notifications that are tied to wallet address and these communications uh they can be on chain they can be off chain they can be gasless but more importantly they are open they are multi-chain and their platform agnostic uh why uh why do we need open communication layer uh well that's just how web 3 operates when we are looking at a crypto wallet uh what we are looking at is our blockchain data that is open and communication needs to be like that uh that's the end goal of epns like famous crypto wallets or public crypto wallets just tap into the epns protocol and show you notifications for your wallet address as and when they come show you chats for your wallet address as and when they come and hopefully video also in some time so yeah how does it work uh well essentially we have uh this thing called epns core it's a smart contract uh it resides on ethereum and any service any person who wants to basically send a communication they have to come and activate themselves on the cpns core this basically becomes the governance layer uh then on the right hand side we have epns com layers these are two layers which enable communication uh the first layer is epns com smart contract middleware and the idea is if you're a smart contract then you can interact with epnscom middleware smart contract and send those communications or notifications out and the second layer uh which we have is the epns com sdk this enables gasless communication so just think about it not everything we do is a communication that requires on-chain uh events or that actually uses on-chain events uh as i said like loan liquidations you don't want to be notified when your loan liquidates i mean that's just sad you need to be notified near uh uh the loan liquidation event uh and yeah you know you just take it further uh think about snapshot off chain uh governance you are not notified because on chain event has occurred and then you know you can build it up so much and so forth think about uh let's say a version 3 of rv comes in again epnscom gasless communication uh can be used to deliver that uh and so on and so forth so yeah uh those that's the epns com layer uh then in the center we have push nodes uh these are basically p2p uh validator nodes and their job is as simple as listening to all the communication that is coming from epns com layers validating it to epns core and if everything looks good admitting it into the network from there on any crypto front end can just tap into the network and can uh deliver these notifications out so yeah uh i wanted to show a live demo but then my team told me that we have a workshop so a live demo is up for that uh just in case you guys are interested uh just come speak to us after the presentation and we can hook you up uh we are going to walk you through the live demo we are going to walk you through how to set this up for your own protocol or for any web 2 or web3 services which you are building that might want to communicate with the wallet address uh yeah a little bit of uh show off uh so yeah we are backed by the best so just uh shout out to all of them to help us build this we just launched on ethereum mainnet a month back and we are going to come on polygon after that and even we are going to come on um all the other blockchains not evm and non-evm both right after uh all right and again uh building the show off out so shout out to all our friends uh when we started like we uh reached out to all these awesome projects and we said that work with us help us create the communication layer uh for web 3.0 and that's exactly what did it uh and yeah any one of you uh if you're building out any uh any of your cool next idea any of your cool next project come talk to us or say hi uh after the presentation or you know just scan the qr code uh that's about it uh thank you everyone um i think i can take questions over here now
