hello hello and welcome everybody thank you so much steven for that amazing welcome and introduction to the developers track of smartcon here we are incredibly excited to be working and talking about this next section that were going into which is whats new in chain link so for those of you who dont know my name is patrick collins im a developer advocate on the chain link labs team here this is what i love to do i love working with smart contracts i love coding i love developing and i love doing kind of everything that this industry has to offer and im really excited to be talking to you guys about whats going on whats whats been happening in the chain link ecosystem what are the tools that have come out from chain link to make your lives as smart contract developers easier better and faster so for those of you who dont know just a quick recap about chain link and the smart contract connectivity problem what is why are we here what does this technology do so these smart contracts as we know are these amazing technologies but they have this fundamental flaw right they are walled gardens they kind of have to stay in their lane theyre deterministic systems and this is intentional this is by design so in order for them to talk to the real world they need whats known as blockchain oracles now a single oracle by itself isnt the whole picture and doesnt solve this issue you need a decentralized oracle network as well because you wont need to have your logic settlement layer on a smart contract platform decentralized and your data or external computation layer decentralized as well and as steven was saying this gives rise to these incredibly mind-blowing applications called hybrid smart contracts that combine this fantastic power of this on-chain settlement layer with the external data and the external computation to allow engineers to build unlimitedly customizable applications and smart contracts in any way shape or form so with that being said if youve been asleep for the last six months were going to give you an update on all the amazing things the developer world has had to offer as far as chain link goes and all the different developer tools and oracle pieces and oracle infrastructures and oracle technologies and to kick us off id actually like to introduce melody the head of developer marketing uh at shin like labs who is going to be talking to us about uh the community and celebrating all the things that you the community has done because at the end of the day its you the developers its you who are building this amazing future and building all these fantastic tools with technology and with chain link so with that ill hand it off to you melody wow thank you patrick for the great introduction and i just want to say that first off before starting if you just want to see my cats and dogs make sure that you follow me on any social media platform because youre bound to see my cats and dogs its just its just gonna happen so hi everybody im melody im leading our developer marketing team here and today were gonna talk about what you folks have been doing in the last few months but first off i wanted to talk to you about uh why actually companies started to care about developers more so were gonna get into some kind of like the were gonna just summarize what happened in the last 30 years and im sorry if its gonna bore you to that so just please stay tuned and stare with us so with that we can actually get the first slide so we now live in a platform economy a shift has happened and this is a shift from the move on to the next slide really this shift is from products to platforms and what i mean by this is that used to in the 1970s good old days companies uh would actually have very linear way relationship of communicating with their consumers so you can see that on the slide theres a traditional value chain business model and in this model you have the company producing stuff distributing it and marketing it and at the very end theres consumer using the stuff hopefully and there is not really a continuous relationship but moving to platform uh previously moving to platform-driven business model we actually uh have the platform and company here and the ecosystem on the other end and these are in continuous uh connections so theres a two-way relationship and they connect to each other all the time so you have the in the ecosystem side you have your developers publishers any kind of players that you can think that are actually in this valley uh creation moving to the other slide and uh trailing is a platform for decentralized oracle networks now that we you know talked about there has been a shift and we have moved from uh products to platforms and were just also established that chain link is a platform for decentralized oracle networks but what does it mean where am i talking about this and how does this relate to you why are you in this presentation right now so moving on to the other slide i want to explain that products have futures and platforms have communities i keep quoting this professor from mit hes awesome in the platform economy resource so if you want to check that out please do so what this means is that in todays world even if we had the best product as chain link even if we didnt have you talking about it developing with it dealing with it and using it it wouldnt matter so we would not really matter and we would not be actually having this conversation with you we would not have smartphone because in todays world if you want to succeed as a company as a platform you have to have communities and when i say communities i also obviously employ our great enthusiast community so it doesnt have to be specifically techno technical industries but to survive in this as an emerging technology company we need developers too so with this in mind i want to talk about that link how we actually uh do our developer community so moving to the next slide youre going to see that we have three pillars namely events open source and community and these are always interrelated so i might be repeating myself apologies for that and youve done some great things in the last six months or seven months or eight months i think were in august so eight months im gonna say and were gonna we wanna uh appreciate this and we wanna recognize this great things happening in the community so lets start with events and so i want to highlight some of these activities that weve done in this last year and the first one is the chain link spring hackathon so we had over 125 thousand 000 in prices which is a impressive we had over 140 projects submitted but as a community person what i want to highlight is that 30 percent of the participants to this event were actually newcomers to the industry and this is huge because if we are in emerging technology were not going to have someone whos been actually doing blockchain for the last 30 years because it did not really exist before so we need to welcome newcomers and we need to actually help them upskill themselves and you know help them get better at this technology so this is why we actually really cared about this and i want to say that maybe stay tuned for patricks presentation because he might have some news for you about this hackathon and the other event that i want to talk to is developer starter kit showcase and this was uh we asked our developers we asked you to create cool stuff amazing stuff using our starter kit and uh as a result of in after a month we actually highlighted some of these picked some of this great cool awesome project and we uh we had this project owners uh in a live stream with us presenting their amazing use cases amazing projects to the audience that we have all across the world and the last one is the smart contract developer bootcamp which is something that i really really really feel really close to because this was something happened in my time at chain link and i do i joined just two months ago though it feels like a year i want to say that when we were planning this event we actually uh taught about reaching you know training probably like 300 developers but we had a pleasant surprise and we had 5 000 people actually signing up for the event and as a result of great work from our developer relations team we actually managed to train over 1000 developers and this is uh this was a really supportive creative environment during the boot camp we had this over the month of july and we provided over 20 hours of content for free to help our community to get better and the second pillar is open start so moving on uh when we talk about open source this is something that we take really seriously at training and uh open source and developer relations you might know that we open source our documentation so thats something thats a really big move from our end and we whatever we do in developer relations is to help us get uh give you the better developer experience so whatever were doing we wanted to uh shorten this loop of feedback so we wanted to get closer to you and get you know uh get out more useful stuff for you and we also have a program called chaining grants where we actually reward open source projects and till this day we had over 50 projects who received grants from our program and you might also see that these announcements every week on our website theyre announcing uh new grants every week and today theres a special announcement for a very exciting grant so stay tuned for that and you might be aware that we have over a thousand repositories on github using chainlink so if you just search for that tag youll see all of those amazing stuff and open source is really you know almost uh really close to transparency so thats one of the reasons why we actually wanted to do we are actually celebrating being open source because we want to be really transparent in everything were doing moving on to the community which is community itself so were talking its a little interconnected at this point i want to talk about what you have been doing and why you have been so amazing so if im uh saying something wrong just reach out to me so uh on this card we have a huge community over i think like 20 000 people and we ha its such an active community if if you ask a question you youre bound to receive an answer we have really great champions within the community who are helping each other and on telegram is more of a place where we use it to just stay up to date and we have over 37 000 people there so if you are a member and if youre not checking it for an hour or for a day youre gonna wake up receiving over like 200 messages so its really fun to be there and if you want to join just visit our website and as mentioned uh github we have so many uh repositories our data community is really highlighting their work and i want to actually highlight the stack overflow and stack exchange because these are support platforms that you are using constantly and we are obviously as developer relations as our team were trying to answer all the questions but what weve see we keep seeing there is that some of the rock stars in our community keep answering each other keeps supporting each other like theyre just there owning this and doing amazing job and which is actually inspiring us which has been inspiring us a lot so with that we wanted to we actually created some program to recognize these people the next slides so we wanted to launch this program that we are launching today uh to celebrate these rockstars the champions in our community because youve been doing an amazing job youre supporting everyone youre helping people upskill themselves and we wanted to actually get better at recognizing you so moving on to the next slide we are now announcing challenge developer experts program which is something uh that is going to highlight these rock stars in our community that is going to help our community get better and we are looking for new developer experts we actually have been uh grateful to pick some of uh form experts from our existing community advocates program because thats an amazing program if youre not part of it you might want to be checking that out we want we picked this for people and they are actually doing some work on translating the boot camp etc so now we are looking for a lot more people to scale whatever were doing so we want you to apply scanning that qr code you should apply if you are someone whos passionate about our technology and whos really expert in whatever were building all our products and you are you should be applying if youre someone who actually likes to help fellow community members because do you think that that is like one of the core values that you should have to become a developer expert because its mostly about caring and uh advocating for the technology and if you you should apply if youre someone who is uh very comfortable with writing technical blog posts or like doing podcasts or videos whatever you choose so we really want you to apply just to please do so and uh because we right now when we look at our community we want it to grow a lot bigger and we also wanted to become you know we want to have representatives all over the globe we right now have folks from argentina turkey germany and switzerland so we want to make sure that we cover almost every country so with that im going to move on to the next slide and i want to thank you for your time thank you for bearing with us and thank you so much for doing amazing job during this year you inspire us every single day so we want to do better for you if you are missing out on anything if youre if youre not doing a good job on anything just reach out to me and you will get a cat or dog picture too with a reply so im with that im happy to hand it over to patrick whos going to talk about some technical updates features and maybe some event announcements awesome thank you so much melody and thank you for the update on the community here uh and yeah i just want to double down on what melody was saying there everybody whos here everybody whos watching uh ive had the luxury of being able to meet all of you or excuse me not all of you ive had the luxury of being able to meet some of you not quite all of you i would love to meet all of you soon at some point and yeah absolutely thank you so much theres theres no way uh any of this would happen without the community right we work in this decentralized this open source uh community this environment which is wildly different from kind of the traditional company world and its just its amazing that we can actually come together collaborate and build these amazing tools and and push this entire industry forward together so additional thank you for myself and with that being said uh lets go into some new features right lets talk about some of the fantastic tools that have come out that make your lives as developers even easier so that we can build new things so we can do new things because thats what were here for right were here because we can build these amazing tools we can build this new future we can build this new world and we want all the tools we want everything at our disposal so we go out and we can do that so were going to talk about some of the new features that chainlink has come out with uh recently thats going to make your lives developer more fun more exciting and give you the power to build these unlimitedly customizable smart contracts and to start off lets start by talking a little bit about the data and the data feeds right because traditionally when we talk about oracles thats the first thing that comes to mind is data data feeds price feeds and as we know this is just a a subsection of all the things that oracles can do but its an incredibly big piece right theres over 50 billion dollars in total assets of being secured by these price feeds in the d5 world right you see protocols like ave synthetics using these price feeds to price underlying collateral to do all these amazing things in d5 and these price feeds are on a multitude of these l1s including ethereum binance smart chain polygon xdi avalanche all these different platforms that allow you as a smart contract engineer to build really cool really powerful applications that can affect and change our everyday lives additionally theyre being rolled out on some l2s as we speak which is incredibly incredibly exciting as we know this is a huge scalability upgrade for our entire industry speaking of l2s one of the first new releases that i want to talk about is whats called the l2 sequencer health flag coming very soon these are absolutely wild these are absolutely fantastic l2s are these fantastic tools as we know these these rollups like arbitrary optimism theyre giving us this scalability um power that we desperately need however they do rely on these sequencers right these sequencers to make sure that everything is going well from the roll-ups from the l2s to the l1s now what happens if these sequencers stop and thats kind of that is kind of an issue that a lot of these applications run into okay if i have this multi-chain application and i have you know half of my smart contracts on an l1 the other half on an l2 what what happens if the l2 sequencer stops updating am i just am i just bunked can people be malicious can people attack my code and this is where these health flags actually come into play here so i have a quick quick bit of code here just to show you exactly what this looks like uh basically for those of you who have seen kind of the price feed code this is basically how you set up a chaining price feed in a smart contract what you can have now is whats called these these flags these uh arbitram flags or these flags for whatever l2 and basically right before you do a call you check to see if this flag is raised down here right so this is this section down here if the flag is raised then you can just revert right if the flag is raised you can revert if your application is multi-chain this will be an essential security feature for making sure that you stay secure on this new multi-chain world especially with rollups so this is incredibly exciting and its as easy as doing just a quick if statement if is raised documentation for this coming out very soon and is one of the features i am very excited for especially as we try to go more and more multi-chain ive been playing with arbitrary optimism myself and im loving whats going on and this is just going to make um that ease of use and that ease from a developer side even better additionally with data feeds uh here is a a fun little gif of me its going kind of quick of me scrolling through the ave github uh now for a lot of you uh who have been working with the chain price feeds or chain link data feeds know that there is a little bit of work of keeping all the data feeds in a config file right and having to kind of go through this giant config file of okay here are all the price feeds heres whats going on um and this has been great and its worked well but were engineers right we want to make our jobs as easy as possible we want to automate everything if possible i dont want to have to write the address of a of a price feed and this is why the chain link protocols come out with whats called the feeds registry so now instead of having to have these giant config files you can just have this on chain feeds contract registry where you can make calls to it and and get the price feed associated with it so lets do an example of this as well we go to the chain link documentation uh well scroll down let me show you what previously it would look like for you to make a price feed call so this is a price feed consumer contract its using the chaining price feeds to get what it looks like fusd in here and the way that you do it is you use an interface and you just pop the address of that uh of that price feed address right and again you can go to whoops you can see exactly what these uh what these price reads are doing what the nodes are on the back end uh incredibly incredibly powerful um we can go down to oops thats the keepers page we can go down to the contract addresses to see these addresses and this works great however theres the improvement here is instead of having to do that is we can have the code now just look something like this so well just say registry that latest round data and then you say denominations.ethdenominations.usd theres this new denominations library that gives you addresses based off of even tokens that arent even tokens so usd for example obviously doesnt have a token address but we can still grab this pair just using this denomination all you need to do is have the single registry address and then you can have access to every single price you that you want so this makes our lives much easier we no longer have to have this giant config file and it is a wonderful wonderful developer improvement here and im really excited to see all the things people build with this registry with this feed registry moving forward so absolutely fantastic large responses and multi variables so uh recently getting data on chain has has been kind of tricky right because if you were to put on a gigabyte of data i think you would bankrupt entire countries right because putting a lot of data on chain is incredibly expensive um so theres been a little bit of trickiness to kind of get these these large pieces on recently genelic has developed a way to get this large data and multi-responses from an api easily into your smart contracts so those who have worked with it know that you can not only get data feeds you can get keepers you can random numbers you can also make any type of http get http post you can make any api call in your smart contracts and additionally what you can do uh is return any type of data back to your contract so lets do an example of returning a massive string into our smart contract so we can do something really cool with that string welcome to welcome back to remix i love working with remix here and heres what were going to be doing were making this api call here so its just a typical http get call and its calling on ipfs an ipfs note that i set up specifically for this demo here its got this image bytes object so this is a bytes object that returns an image url so for those who are familiar with image urls you know that this is a key piece to nfts and working with nfts so we have this this bytes encoded url and i want to get it into my smart contract so maybe i can use the the cid for an ipfs hash or maybe a file coin hash or connect to some d storage or something like that whatever i want to do in any case all we have to do now is exactly the same as what weve done before with working with chain link but instead of returning a byte 32 we can just return an arbitrary bytes object that is any size so lets go ahead and compile this contract and well deploy this onto the onto the coven chain and well get the response and well see if we can actually read the read the url right off the chain so i got some covanese here were going to deploy our generic big word contract here metamask is going to pop up confirm and were going to have to fund this again for those of you who are a little bit unfamiliar with how the chain link request and receive model works im going to fund this with some chain link token so im going to copy the address send it a little bit definitely definitely overkill uh with one here because i think the fee is like .01 or something that well send it some of this link token and then we can request we can make an api call to these chain link nodes and they will return it will respond with this url again this is absolutely massive because now we can store these mappings to ipfs we can store massive pieces of data we can do really whatever we want to do here just keep in mind when youre doing this of course dont store a gigabyte of a responsive api because you will you will go bankrupt very quickly so well call our request bytes here and as were waiting our data and our image url view variables are going to be blank right because we need to make that first call to the chain link node and its going to respond with our image url and with our data here so once the node processes our call and response its going to say hey heres your data thank you so much um appreciate to appreciate the call here and well be able to actually use this string in our in our smart contract for like i said for whatever we want to do and theres a little bit of an easter egg based off of this hex here if any of you can parse hex in your head uh type in the chat what you think this is uh although none of you can parse hacks in your head but some of you are quick you might be actually able to do it um with some screenshots and copy paste in any case the chain link responded and we have this giant bytes object in here now and now we can check the image url because we just cast this bytes object as a string and we get this wonderful ipfs url and lets take a look at what this is and its this beautiful sunny chain link logo isnt that adorable some of you might have recognized that chainlink logo from a previous event that weve been in the past if you know what that event is drop it in the chat ill take a look at the chat later but so thats the multi-word demo in the large responses you can get these large responses and also multiple variables in a json object which is incredibly powerful and incredibly exciting moving on to more exciting releases and more exciting features ah theres so many exciting features and releases keepers general availability i believe this was talked about a lot yesterday uh which is incredibly exciting and this is one of these things that allows us to do so much more its one of these external computation its one of these these event driven metrics that weve never been able to do before in a decentralized context which is incredibly powerful the way that it works is we have some smart contract right and the chain link keeper networks keepers networks is costly calling this function called check upkeep on our contracts and its just checking its just saying hey is that event ready is that event ready is that event ready because were looking for some event uh to kick off the keeper network right now if i want to if i want something to programmatically update i need to write a script myself that monitors the blockchain thats obviously incredibly centralized and doesnt really scale very well if im looking to make a depth the keeper network will be that human being will be that network thats sitting behind check constantly checking and then calling a function and creating a transaction for us and this and it allows um your smart contracts to really do anything because of the way that its its built to be incredibly flexible and customizable to return data and return some type of computation in any way you like so this is this very powerful event driven application decentralized event driven smart contracts which is incredibly fun now i have a little demo here just to show what this is doing so i have a typical nft contract here but the nft contract needs chain link tokens because it is a verifiably random nft contract here so nftas get minted based off this verifiably random application but what happens if the link balance drops to zero no more nfcs can be minted right and this obviously is terrible for anybody whos looking to use the platform so what were going to do is were going to use the chain-link keepers to constantly top this up with link to to make sure that people can continue to mint their entities and again this is just an example of the chile keepers you can use this for literally any use case you like so lets do this live well do brownie run scripts well do not deploy mocs were going to deploy the collectible and well do deploy.i dash dash network coven and theres a little bit of python here but typically what i do when i deploy one of these nft contracts is i fund them with link i have intentionally commented out the funding with link so its going to start with zero link this contract has no link so no nfts can be minted boohoo so sad i know im so sorry um but im not because the keeper network is going to do this for us ive added to this application a backup contract or excuse me a backup wallet that is going to allow the keeper network to send funds from my backup wallet to this nft contract so were gonna go ahead and deploy this on the coven network and weve got to compile and get all the cool cove and stuff great were sending this to coven uh and like i said we arent going to let me let me grab the adders here we arent going to have this contract have any link to start with which means nobody can uh mint any any nfvs so lets go to the coven ether scan here and lets take a look at this contract that we just deployed so we have this contract this is an nft contract has no link it has no nothing in it and weve given uh the keeper registry access to a wallet that has some testnet link in it and in my contract in my advanced collectible whoops thats the readme i have this check upkeep function thats defined uh lets scroll down to it lets see what it looks like all its doing is checking to see what the link token balance is its saying hey if the link token balance is less than two do something return true and once it returns true the keeper nodes go ah okay now we need to perform some upkeep they call this perform upkeep function and all it is is it is a token transfer so you can see right here this is incredibly customizable that the the check upkeep function can be whatever you want to be and so can the perform upkeep again this is in this decentralized context so what were going to do is were going to register this contract with the keepers registry here so were going to connect our wallet to the ui here this is a this is a ui for an on-chain contract here were gonna confirm were gonna connect here and were gonna go ahead and register a new upkeep so were gonna put some email address in ill be patrick.collins at well do an update name ill call this nft smart con well pass this address in here which i think i lost my copy paste so well copy it again pass this address in here well do a gas limit which is approximately how much gas this should cost we dont have a check data check the documentation for what this check data does and well give it a starting balance of five link so we need to fund our registry uh because we need to pay the the chain the keeper network link to work with this so we we have two different fundings right we are funding the registry application were not funding uh rnft so lets go ahead and register this upkeep metamask pops up says are you sure you want to do this we have this transaction thats going to come through and this will actually register our upkeep now youll see when we get to the once this finishes registering we can see on chain im just going to do everything through the ui here but well see the amount that we have funded with our registry application great lets go ahead and view the upkeep here well see uh we have this balance here of five link this is how much uh our and if uh our keeper uh is currently funded with to to do this execution and if we look at our nft contract right now uh its still going to stay as zero uh and once the keeper network picks up and says okay we have a new registered we have a new registry here we have a new registered upkeep its going to go ahead and start calling check upkeep and then perform upkeep again the checkup keep is going to say hey is the link whats the link balance here whats the link balance here and then if the link balance is lower than this which it is right now its zero its going to go ahead and start sending us some link which is really exciting so if i hit a refresh here um in a minute uh well see this this actually update so a little bit about the keepers they actually call on this check up it looks like its updating right now it actually calls this check upkeep function uh every every x amount of blocks depending on the network which is really exciting and you can see live the balance actually starting to go down so this is the balance of my red nft registry and if we go over to my contract we do a little refresh here we can see the chain link token balance actually going up so this is the keeper network actively funding my smart contract without me having to do anything im totally hands off here this is decentralized doing some event driven activities and if we hit refresh again lets see if its sent lets see if it send more tokens okay it didnt send more tokens yet but it looks like it just it just updated again so if we hit refresh again itll send some tokens but uh you can see thats how it actually works live on the back end which is incredibly exciting dont you love it when live demos work too thats the best so thats that application and now we can go ahead and call this minting function on these nfts because we know we have this this minimum threshold because we got the chain-link keepers got our back the chain-link keepers got our back so which is incredibly exciting some more absolutely fantastic uh applications oh sorry theres a theres a train outside i guess uh if you guys can hear that so some more uh wonderful uh advents in this space so for those of you who have worked with the chain link contracts npm package the brownie package has actually now been updated to constantly mirror that so if youre working with python if youre working with javascript it doesnt matter the tools are going to be exactly the same which is incredibly exciting and speaking of brownie javascript and python the solidity and smart contract starter kits are absolutely must must must see for those of you looking to start building one of these smart contract applications whether its truffle brownie hard hat any of these fantastic tools that makes our lives as smart contract developers easier there are starter kits that have all these technologies built in as a starter as a starting point as a piece of boilerplate code to get you get you into the action asap you can just do a fork on these we have a ton of videos on these showing you how to walk through them what theyre actually doing i highly highly recommend if youre looking to start a new project checking out these starter kits because your life is going to be substantially easier as developer faucets faucets are a wonderful wonderful thing that we have in the smart contract world that makes doing our integration tests a lot easier right so youll see later when i do my productivity presentation later we dont always want to work with test nets because they are a little bit slower and we do have to wait a little bit we cant iterate as quickly but we still do want to work with them because we want to make sure our integration tests work we want to make sure that um the contracts are actually gonna you know act in the way that we expect them to uh faucets have been this point of contention because were always asking hey where can we where can we get some tests at eth for covin for for rink b for for whatever if you head over to the link token contracts page the most up-to-date faucets will always be underneath the test net so if youre looking for excuse me so if youre looking for some type of test that link come to the link contracts page you can check out coven rink b et cetera theres obviously of course the test that link page that gives us some test that link but we also have example for coven a test on each page which looks just like the link page um which will youll pop your address in youll say send me point one test eth and youll get some test e so if youre looking for where these up-to-date faucets are always check always always always check the link token contracts because its gonna just its gonna be the place that has all the faucets and its gonna make your life a lot easier faucets absolutely fantastic so weve talked about a lot of fantastic things here weve talked about a lot of wonderful new features and i i like i feel i i was nervous i wasnt going to get through them all because there are so many so many things making our lives so much better now lets talk a little bit about the future and the different pieces that are to come because again the reason that were here is because were building this better world right of with hybrid smart contracts that are combining this on chain this wonderful advent of smart contracts and and blockchain technology with this off chain data this off off-chain computation to make unlimitedly customizable applications right and really do anything that we want to do so as weve seen were working with this incredibly one of the one of the main stakes here is this incredibly highly validated data right these these data feeds that are being used by these these giant billion dollar protocols like you know like ave like synthetics like compound these absolutely massive massive uh massive detail protocols being powered by this uh however like i said oracles do so much more than just data and oracle is any device that connects a blockchain connects your smart contract platform to anything off chain be it data be it smart uh be it execution whatever you want its that bridge its that connection piece so highly validated data that is the that is the low hanging fruit that is the tip of the iceberg here as you as i just showed with keepers theres more of this off-chain computation coming to make our lives as developer easier weve seen work with the chain-link vrf i didnt show it here but the chain-link vf to get truly random numbers the keepers allows for maintenance spots allows for these upkeeps to happen allows us to do this event driven work uh more of this expanded computation coming down the pipeline giving us the tools giving us the power to connect these smart contracts to the real world because at the end of the day thats really what we want to do these smart contracts are are cool right theyre absolutely fantastic and on-chain token transfers is great but we want them to actually affect our everyday lives we want them to be these digitally superior agreements we want them to actually be able to have some agreement that can cross over from this walled garden that is smart contracts that is blockchain so theres more and more of these features coming out more blockchain support more smart contract platforms to work on that are both evm and not evm chains so stephen talked a little bit about rust for example theres some fantastic rust smart contract platforms that are becoming more and more challenging compatible as we speak uh yesterday one of the big pieces that was announced was the cross train messaging the chain link excuse me the cross chain interoperability protocol which is going to be absolutely bonkers to be able to work with work with any chain you want seamlessly working with these different bridges these token bridges um a chain link vrf2 is in the pipeline for more subscription based uh chainlink vrf for confirmations for some more randomness expansion built in uh note as a service there are all these features that are coming and coming down the pipeline and were beyond excited for and now melody teased this a little bit we are incredibly excited to be announcing the date of our chain link hackathon our next chain link hackathon this is going to be our largest hackathon ever and its going to be october 22nd is going to be the start date so mark your calendars because this is going to be a wild hackathon be sure to sign up for developer newsletters to be one of the first to sign up so for those of you who didnt attend the last one i melody gave a quick recap but id like to go on a couple of those those features as well uh some of these hackathon products have gone on to raise millions in seed rounds right so not only have a ton of new people come into the space with these chandelier hackathons but a ton of people in this space have gone up to do amazing things something that i i love pointing out here is that mark cuban became an advisor to one of the winning projects of the chain link hackathon these are these are some of these are real projects really going out and doing amazing things so if you want to kickstart if you want to jump start your career here if youre saying hey ive learned solidity what do i do next a thousand percent be sure to go to this chain like hackathon because the tools the community the networking at this event is absolutely absolutely insane uh so i see i wrote here half the attendees i think melody was correct but being about 30 of the attendees are new to the space so you know if theyre like whoa patrick that sounds crazy that sounds intense im not ready to do all that perfect absolutely perfect if youre new to this space welcome you with open arms this is one of the most welcoming communities ive ever been a part of and encourage you to say hey you know what im going to give that a shot im going to try this out im going to try this hack upon out i might be a little bit nervous with my skills i feel like i have imposter syndrome dont worry that is the perfect place to be and youre going to be well received because a lot of people are feeling the same way so feel free to just show up uh try to do whatever you want to do you can go as far or as not far as you like this is an opportunity not only to kick start and go far into the future but also just get started and dip your toes in so wherever you want to be were planning on having three tracks uh based off of this this uh this narrative that i just mentioned uh the first one being kind of a going mainnet bounties these are for engineers looking to get in front of vcs go main in as soon as possible were of course going to have our traditional bounties this is for sponsor prizes d5 bounties nft bounties chain link services which is going to be absolutely massive people looking to expand on the chain link network and build new tools and build and and tinker and study and and try to come up with the next keepers or the next chain link vrf or the next next service the next data dow or something like that these are for people looking to looking to explore use these hackathons as a method of learning and growing and networking and then of course the getting started bounties for engineers who say hey im a little bit nervous and they maybe just need that little kick to say you know what we know youre nervous but youre welcome here and wed love you to come and try and just have fun and have a blast so these are going to be the three tracks of that chain like hackathon that im incredibly excited to work with now basically to close up this talk uh just talk a little bit about why engineers love working with chandling and why i love working with chandling theres this unmatched security there are unlimited possibilities the customization that you can do combining your decentralized on-chain and your decentralized off chain is literally limitless i say this a lot but when it comes to these hackathons and when it comes to chain link youre really only limited by your creativity which is something not a lot of industries can say chain link is this dev first experience im an engineer pretty much everyone i talk with and everyone i interact with engineers and we we care we want everyone we want the you we want the community to be able to go out there and be empowered to build these fantastic things this dev first experience i absolutely love and were here to support you and give this accelerated momentum to build and do whatever you want to do so this is the chain-link journey that we as a community are on that you are on weve started with price fees we started in this first wave were moving more towards data feeds the data marketplace the randomness keepers were getting more and more of these tools to go more mainstream order fairness advanced offchain computation full support of all data also we can transform the world make it more economically fair give more economic equality opportunity for everybody and rebuild institutional trust along on this journey with amazing opportunities uh in every facet and every walk of life so with all that being said i want to give a huge huge absolutely massive thank you to everybody whos watching everybody whos been a part of this community everyone whos not watching everybody whos made

you everybody so much for being here we have an amazing journey ahead of us we have amazing things to build and im excited for us all to be a part of it and work towards this future so thank you awesome thank you so much melody and thank you so much patrick for your awesome update on chain link i was watching the chat and i heard a ton of call-outs about the love for the channel community
