A

All right, let's give it another minute waiting for uh for dmitry who will be presenting right after my introduction. So we kind of gotta have him on.

B

Ironically, it's the most hard to join this conference when your organization zoom doesn't allow you to go with the flow you have to do something else.

A

All right, I see him. Okay, I think we we get the most important people on the call, so welcome to another awesome edition of uh the fluence community call. Today we got a pre-packed schedule. uh Dmitry's gonna have an update from the cto office. We have uh multiple hackathon participants presenting their solutions. We have possibly drier presenting part of his work in continuation from last week or the week before I forget, and then we have alexey from our side presenting uh the details. The extent by examples on registries basically continuance from the high level overview.

A

The last call- and I think uh last but not least, our other dmitry- is gonna quickly go over the aqua cli changes. Some of them are okay, forex will do it and uh and yeah. So, let's get going metri all yours.

C

um Hello, well, we we've been working on on the registry uh and fixing various small issues all around that led to the release of the new aqua 0.7 and the new fluence js version and the new compiler support v3 uh in the fluence.js side.

C

So a lot of small changes but alex say we'll uh we'll show show it show the result, the effect uh how the registry can be used because, finally, it's done, uh which is uh super good uh and uh and what else and we have some something not not not absolutely completely yet under the hood. But good news are about about to happen, but not today. Let's focus on was done on alexia and dixie, and the demos.

A

All right, uh anna, you want to introduce our hackathon presenters.

B

um Yeah I can help. Can you hear me.

D

Yes, yes, I can hear you um are you ready? Do you want to present today, ah yeah sure sure cool yeah go ahead? Oh okay! So uh uh we're gonna start with my presentation right now: okay, okay uh yeah! So uh maybe I will just start uh right now and sharing my screen.

D

Okay, I hope you can see my screen now guys.

E

A

Yes, yes looks good.

D

Okay, um uh first of all, um my name is helmy and thank you for having me in this uh community call, uh so I was participating in uh these bounties for the beginner challenge that um integrate the um api from openc and variables with the fluence library and what I built here with my friends, nico he's also here in the meeting, and we are creating what we call with open pond.

D

Basically, this is a very simple application, instead um listing some nfcs from openc and variable, and I will maybe just uh demonstrating how the apps works. Basically, it's just displaying some items from opencn wearable.

D

I guess there's a little bit problem from loading from the openc testnet api, but you got the id so in the home page we are displaying some nst items and we can also connect our meta mask here in rinkaby testnet network to see is there any collections that we have so I have connected my world here in the rink b network.

D

And, as you can see, I got some collections from openc and also from variable I'm going to open from the writable one.

D

That's our context sometimes, and as you can see, that we can also open the nfc items on any collections that we have, so uh that is basically how the open ponds work and maybe I'm gonna go through how it works um from the system and code. So, uh first of all, um as mentioned in my uh github documentations, that for the back end, we are using marine rust sdk and we generated the uh web assembly and then we uh deployed in the some cross node our nodes here.

D

So we can uh access it from the public uh address from anywhere and and yeah. So the the marine rush that we are generating is coded right here.

D

As you can see. I have two um I made here the first one for accessing the variable test net and the other one is for accessing opencv testnet and basically it's just contained function for uh for getting all the assets here. Here's the uh the test api and then it also accepting parameters for the size of the items that we want to load and also continue token.

D

If we want to load uh on a continuous page or if we want to load the next page of nft collections and also I create a function for the owned collections from the variable and also the only assets by the collections and that basically, what is uh I, I read the code in the rust and also the same here in the openc uh rush things, and after that, we we build it as a web assembly, and then we upload it with uh with a oh sorry with a function here that will upload it to the quest modeler and then I'm also creating the aqua files here.

D

So it can interact with the react.js react. It can interact with our front end, as you can see here. um It basically just uh tells where's the node supposed to be connected, and this is the node from the cross model I have uploaded earlier, and this is some implementation of the rust functions and then from here we built the aqua and it's outputting some typescript here- that we can import in our main front-end code here.

D

So I'm importing from the typescript that have been generated and we call the function as easy as this like calling the aqua interface and the functions like get all sets and setting the size of the items and yeah. Basically, that is how uh the open pond works here. Yep. I guess that that's all I can show you guys about the upton pond, um okay, and I guess I will returning to to you guys. Thank you.

A

Okay, thank you very much. Anybody have any questions.

B

Yeah, I have one so so this allows you to to like have some state about user on the fluent service, so you can gather collections and stuff that does it somehow enhances the api that openc and variable give you that's my question.

B

uh I'm sorry, can you repeat the question yeah sure: does it somehow give you a does fluency here, give you additional features uh that simple, openc and wearable api. Don't.

D

Give you um well uh basically it's it's not uh we'll just making the um the friends as a back-end that requesting to test tested api, so I mean basically, if you request um directly to the testnet, it can also be work, but uh I can see, uh as I see from the influence that we can actually change some some request to to be um working uh in one direction, so I mean from the front end we can just repress once, but in the fluence in the back end they can change some uh requests, uh but for the uh for the challenge I I uh participate is uh it's not.

D

um I mean not as simple as requesting the assets is enough, so I'm not implementing some others um complicated, a request that maybe you know like. If you get the collections id and then automatically list all the items I mean, I can do that with influence, but um unfortunate. Unfortunately, I'm not yet implemented in this uh open plan challenge yeah.

B

I like the architecture that it allows you to implement more business logic, confluence, yeah, yeah, great cool. Thank you.

A

So now, of course, the follow-up question is: uh when are you gonna implement the additional business logic.

D

Well, um for the uh I mean from this bounty, I I also uh at the at that time. There's also some intermediate challenge that um maybe uh require us to create a more complicated business logic. But um I guess I have a run run running out of time, so I'm not yet be able to implement the the more complicated yes ones.

A

Right make sense when, when you're ready reach out we're happy to like uh help you and uh happy to obviously watch the project grow and uh and uh sure cool anna do we have anybody else.

D

Thank you helmi. If raul is here.

D

Can you say something if you're here not sure, because you know.

E

Yeah, yes, all right, hello, hello! So, like I'm going to say.

E

uh So, like uh I have participated in this big net challenge for custodial uh waltz api, the dragster nft events on openc and readable marketplaces.

E

So I have just created this nfd monitor service using the aqua framework uh in which I have implemented. Two functions send message and return result in the send message we are using the functionality to uh like it implements the functionality for the peers to chat with each others and return result. It just returns the result from the peer to another peer uh so like I just have opened it.

E

So I have created a modal here where there is a peer id and relay id for each beer, then we will copy this here again. Just connect.

E

Now we can also enter the wallet address that we would like to track I'll just address.

E

Now we can also chat with the peer like here: hey this there's a message appear now. We can also track this sphere uh when he or she will create a nifty.

E

So I have this test jpeg, which I will use to create an nft.

E

E

So now it's listed now we can select here.

E

You can set a custom amount for it, like this complete listing.

E

And now this spear has started uh monitoring this wallet and which will return the result to this sphere so like um in this ubuntu api.

E

We'll just wait for like a few seconds.

E

Yes, as you can see like we have displayed this party uh payment, you can use contract, address the quantity and the transaction block cash and then created it.

E

E

This is the code for this yeah.

E

The select relay we have adjusted the services.

E

uh When we are sending the message to the peer, we are displaying it in the console logs like this.

E

Yes, that's all from my side.

A

Very cool, thank you. uh Anybody have any questions.

A

Well, I have a question: uh if you, if you ex right now, you have a lot of interactive components in there. Have you thought about making it uh more autonomous, so non-interactive and if so, how.

E

uh Like yeah, I have implemented the feature like uh for sending this images and like also but yeah, I've gotten successful in that.

A

A

All right, thank you. Thank you very much, very cool, congratulations to both of you and uh who's next.

A

I'm looking at I'm looking at jura, but he doesn't know I'm looking at him because obviously this is this is.

F

It's a gallery: that's not a room, maybe you want to put. I will go in between the the next two things or whatever, um so I've been working on on the the project I'm working on, which is uh like a data aggregation uh using fluence. So I get governance, data of votes from daos on the blockchain and I store them in an ipfs structure, and I also make a widget- and I talked about this two weeks ago and since then um it's been running more stable, much thanks to dimitri's suggestions.

F

um I've also created a little bit of confusion uh or with regards to stability to about some other nodes, but I think that's. Okay now, um but in general I believe it's working stably now, which is good, uh then uh what I wanted to do, because what you saw two weeks ago was just an aragon dao, which I used, because they have a reliable front end.

F

That was easy for me, and so now I because, as a proof of concept, I wanna um use a different sort of dowels and then have them uh produce the same data structure.

F

um And um so I was looking into the open zeppelin contracts and I made one and I made a form to do that, and then I wanted to incorporate that into the workflow.

F

And then I really started doubting about whether I actually should use uh the graph, because up till now I've been like getting an event from the blockchain and then getting the data through the graph. And then I started thinking. I've just been thinking about whether I should keep doing that or just store all my own data in ipfs.

F

um And while I'm thinking about that, I thought I'd have a look at the new registry functions that you guys have made and talking about all the time.

F

So I've been doing that uh yesterday and today and I'm making progress with my mental map about what it's actually supposed to do and I'll probably have a question tomorrow, because it's not yet completely working on my side.

F

A

F

Well, encouraging, uh um and now I probably have a question I went after the demo because that's about the subject right, I'm not gonna talk about it. Yet all right.

B

Well drum rolls drum rolls alexa, hello, hello, you can call alex and one of two will will appear. That's handy, that's handy! Okay! So do you hear me well by the way wi-fi so yeah? I suppose you do.

B

B

So what I'm going to talk about today is about this black window or like semi-black, it's about the console utility that we have. You probably know it. It's the aqua compiler. uh It has changed its user face inside now. It should be more understandable and easier to use.

B

What I'll do. I will go through all the well most of the comments that has the most important ones and will describe the changes and what they do. If you don't didn't know before you will know so uh this is an echo compiler, the third, the first, the its most important function is to compile aquascripts to typescript, javascript or air.

B

I hope you know what air is. It's our low level language that describes all the orchestration and aqua is the high level language on top of it so uh aqua.

B

I hope you know what it looks like if you don't. It looks something like this. You can like uh say where to go and what functions to call and what results to bring back or to don't bring any results, but for demonstration purposes, it's better to return results. So this simple script, let me make it bigger. This simple script goes to this node through this node and it asks this node to identify itself and to return information. That's not very important! That's just like some background.

B

If you never seen aqua before so, does some network uh hopes and then comes back to you with the results? What you can do with this code? uh You can compile it. Of course. Let's do that.

B

So, let's first take a look at the help again. So um since the most important feature of this tool is com compilation, it's the default command. You don't have to like type any comment. uh Sub comment to to do the compilation you just type aqua. You provide path to. Let me make it this bigger too. You provide path, sorry for scrolling. You provide path to the input files, it could be a directory or it could be a single file.

B

In my case, it's going to be a single file, so let me show what we have here in. I have this demo folder and it contains icon.

B

So aqua minus minus input, script, aqua, output, like here too, and we have uh by default it compiles to typescript.

B

So I won't go into the details. Yeah I mean I trust myself. I won't go into the tail so what's happening inside the typescript. I will just say that here we have get pure info function, and here we have this function too. So now you have compiled like. I have compiled aqua script to typescript and now you can.

B

Anyone can import this function in the browser or in node.js application and run it, and it will return a promise with the data with the data about the peer that we requested with this info.

B

So great we have compiled it to uh typescript. What else could we could we do? We could compile it to js by providing minus minus gs, it will do create a js file and type bindings type typings. If you want to use this js with typescript great and also you can provide minus minus air, and this way you will get a pure air code with some comments in there it looks like lisp, it's a low length. Language, don't be scared.

B

It describes all the network things that this this script have to do to perform is its job. Okay, so with the core at the core, the aquacompiler always does the same things like compiling to typescript to javascript to air. It's always at the core, the same thing. It's always combined to air. You see it's the same air script in typescript, but when compiling to typescript or javascript so many script words, it also adds bindings around air. So it's easy to use in the browser.

B

Okay, so that was the compilation. Hope you bear with me. So, let's see what else we have here, the most important work on like this compilation thing it was there before it. Hadn't changed. um I guess at all. uh Most important work was happening on the sub comments, so the goal was to make aqua minus minus help, a thing that you can learn from. Like you see that you do minus minus help. You get this a lot of options that you might seem scary, but the subcommands they should educate uh everyone who uses cyclone.

B

It says that aqua has devolving six important things to do. It can run aquacode and compile. Of course it can manage your like key players that you, like private keys, public keys that you use to uh run microscripts or you can manage in browser uh ipv5 doesn't matter much, but you can like connect to ap. First node then get files from it stuff like that, doesn't matter much what matters is the managing schedule? Scripts, it's the script subcomment.

B

It allows you to to schedule a cron-like jobs on the network that go on uh run every three seconds or five seconds or seven seconds. As you say, you can specify the interval and the script aquascript will run on the network like on some specific node again and again and again until you remove it, you can interact with the remote peer. I will that's the one of the most interesting sub comments here.

B

Besides the run, we will go into detail, but basically you can say: hey this beer deploy service, remove service stuff like that, and some configuration- that's mostly non-existent right now, but it's an important thing will be evolving, so we have like made it a separate theme.

B

So um we saw the compilation now, let's to look at how we can run the aqua code, but before we can run the code like compiling didn't didn't require us to connect anywhere. You can just compile and have files on your local file system and that's it. But if you want to actually run aqua code, you need to decide where you want how you want to connect to the network. You need some entry point, some relay some node and you need its address.

B

How do you know it? You can like google fluent spears addresses? Maybe if google indexes our documentation, you will get to the right place, but.

F

B

It's a hard way: it's not very handy, what's handy is just type aqua config, if you forget the full command and you get default peers here. So it lists as it says it lists addresses of default, pierce influence networks, that's the peers that we know about, or we might maintain- and we provide you here, so you can copy paste them or use in any way. You want that's just a static value.

B

It could change only or on aqua release. So let's take a look at it. So here we have like a default environment. It's called krasnodar and all the nodes like cross, 0, 0, cross, 0, 1 and so on. There are 10 of them 10 nodes, but 11 11, fluence, nodes, 10 hosts, but 11 frequency nodes, because the first one costs 2 fluent nodes. I guess that's kind of confusing, but it's really easy. It's just an address of the node you can connect to. So that's nice. Let's actually run the echo code.

B

How we can do it.

B

Let's take a look at the help: wow, it's it's a big one, it's a big help, but we already saw how compilation works so run is alike to it. So what we need to provide is we need to provide input right like path to a directory with aqua files or just off to a single local file.

B

We have run aqua, which is here right and we also need to provide address to connect to, and but that's not all so, let's take this address and also we need to provide a function that we want to call like. Let's take a look at the script once again, so we have this run aqua. It has a single function, but it could have more functions right like and in this case, when you run, you can just run a file, you have to specify which function to call from the file.

B

So in this case we need to provide minus minus minus func uh name get pure info, we just copied and we need to call it. But there is a problem. Oops. Sorry, for that there is a problem. It takes an argument, so you have to pass an argument right. Let's take a look at it again.

B

It takes a peer id to like it takes argument that says where to go to call the function like network address, so let's provide it in this case. It's not the whole address.

B

It's just the this part of the address so like this part of the address it specifies the first part it specifies uh dns name and the host name like where to connect and to what port through web circuit, but this part specifies the public key of the node, and when you have public key of the node, you can always discover node in the network, so aquascripts internally. They operate not on the this tcp part, not on this.

B

They operate on the public key part, which is also called prid, because it's peer id is derived directly from publicly okay. So we have this. We have aqua run uh this file connect to this node and call this function like get pairing for passing this parameter as an argument. Let's do that there is no buffer on aqua.

B

There is no buff.

B

What am I doing wrong? ah It's not run awkward, it's sorry! It's script, aqua.

B

B

We call it and we receive the data returned by the by the node, so we have run aquascript and it's very useful tool for debugging, like whenever you report the bug. If you include, if you make report in a way that's runnable through aqua run, I will love you forever for real because it makes debugging or and understanding your words so much easier. So please always include a quran comment to reproduce your problem.

B

If you can it's not always possible, it could be hard to understand, but if you can please do that makes our work so much. It makes it so easier to help you and we can help more fast, faster, great, so hope your viewers still bear with me. If you have any questions right now, just tell them just ask them.

B

I'm gonna clean, clear the screen yep.

F

Nope, oh well, I can go so. My first thought is that you really want me to stop using my sort of typescript functions that I use to do sort of similar things. No, no.

A

You want to use stop using fldist if you have used it. No, no.

F

um No no, but I I I'm I you know I there is like sort of this sort of functionality, which I repeat a lot of times and then I write a little function for it and I so that I can use an npn command, but it's also true, but what you said at the end is that if we all use the same methods the same way of looking at things, then it's much easier for me to contact you and ask you a question.

F

You know yeah, that's true of the past days. It can get sort of confusing when I'm using my own code to do administrative things.

B

Yeah, but this is a very simple tool: it's powerful, but but real simple, and in your case I let me give you everyone. Some background drawer recently uh gave me his awesome project and there was a problem that was hard to debug and I have to like read the code and run it and what I was doing. uh I was taking your code and running it through a quran like it.

E

B

uh uh So you can have typescript like uh complex typescript things automated through package.json and npm run. That's totally fine! We do that as well, but sometimes when you and I uh debugging stuff or just want to test some simple thing, it's easier to use a quran and for bug reporting. Aquaran is just a blessing, but it's not always possible. Sometimes you don't know where the bug is. So you have to report the whole project. So don't don't make that stop you if you find it hard to translate your problem.

F

But things are hard and then you find the easy solution, but then you don't learn how to do it. um Well, I'm being honest here I had one other thought: um can you make this this client could be written in, could could you make this client um uh listen affluence application.

B

You mean, like listen for incoming requests, that's what you mean.

F

Because you can, I believe you can write something like this in in rust, right that create console.

F

So if you connect to a local node and from that local node, you have services that do this stuff and then you can be in connection with the network.

F

A

Yeah, so so on, I want to follow up on that, so I have two questions on it and one was: can we use it as a as a listening client as well? Can you take incoming via relay.

B

That's functionalities planned, but there was it wasn't a felt list before the previous tool that we have that we deprecated with this new stuff. But it's not right now in aqua because we asked around and nowhere and wanted it. So if anyone would start wanting it, we will add edit.

A

I I want it uh the the other thing is: uh uh uh how do I in now in aqua config? How do I get the uh addresses from testnet or stage, for example, other than just.

B

That's a great great great question: let me show you so so we have aqua config default yours, it's a little bit like uh it's a little bit hard to to get but like to understand, but here in help it says that you can pass cross on our stage or test net as an argument. So you can pass here testnet and you will get it.

A

Okay, that's all I wanted to know. I wanted to have it on video, because obviously people who used the tools before coming from fl discs, that's a little bit different and a little bit more nesting but uh long term. I think the nesting will not lead to backward breaking changes anymore.

A

So I think that's really really good news, hopefully, but I think it's much more robust than what we had before, so anybody who's been using aqua for a while or I feel this I know you're going to have a little bit of pain, updating your uh your scripts and your code, but this should future-proof you quite a bit.

B

You talk from the experience right.

A

From the experience- uh yes, okay, anybody else any.

B

Questions and I still have and after questions I will describe how aqua remote works.

A

I think, if kenny had a question.

A

No, my question was very stupid. Okay, all right.

F

Micro, remote work.

B

Yeah, so aquary mode allows you to interact. Let me clear everything allows you to interact with the remote peers, like all peers are remote except local ones right, but here uh you have uh comments to interact with the peers. Like you, you know I want to deploy to this node. So this node is my remote peer. I want to deploy there. I want to remove service there. I want to interact with it, so I'm here, it's there so remote.

B

So uh it's mostly the same as what it was in apple dist. Here we have a way to deploy service from was modules like you provide the usual configs. It uploads it and creates a service you, you can remove service and if you already deployed service before and you already uploaded the module- and you have blueprint id so for more, like advanced uh use cases for performance reasons, you can just use create service instead of deploy service to avoid re-uploading modules.

B

Every time you can just recreate the same service again, if you wanted uh so at blueprint, is just an internal mechanic. If you you want it for for truly advanced use cases, usually you you're covered with this free, so those functions, the the those commas the the four four last comments uh are more like querying querying the peer. You can ask it: what web assembly modules do you have, for example? Let's do that, so a query mode. First, I will do aqua config default peers, because I wanted to take some beer like this one.

B

Then let's do a query mode under this, and I want to ask it for to list all webassembly modules that it have. It will have a lot of modules, so I will put the comment into the less, so we can scroll it why? What? What?

B

Let's do it again, unexpected option? Other.

B

ah I always forget that you have to put. I always do that mistake. Maybe we should fix it like on the cle side, but what you always have to do right now. Is you always have to write the comment right after the remote? So in my case it was a mistake like like this, I first minus minus other and and then only then I entered the comment. So that's that's not the way. It works. Okay, minus minus other list modules and put it to less, because it will be a big one.

B

So yeah you can see that there is a lot of a lot of modules. They have their hashes, they have them config files, they have their names. um So that's all webassembly modules that were ever uploaded to this node to to like this node great. So the this is a querying querying stuff. You can query some information. You want to know about node, for example, if you know you have a service, but you don't remember or don't know or someone else has a service, but you don't know what functions it has.

B

What what's its interface, you can do get interface.

B

Minus minus id, for example, aqua ipfs like here, we have this service aqua ipfest, and it will give you a big big, big json that describes the interface of the service of the facade module of the service. So, for example, here we have function with name set local api multi-other that takes one argument, uh multi-other of type string and so on and so on. We have a lot of functions.

B

uh Sorry for scrolling, like we have get from functions that allows you to to download file from some from some node. You can provide hash and you can provide external multi-other and it will download download the file from external iphos node to local fluence node and after the like, after all the functions at some point, you will start having types like structs like, for example, iphones multi-other results uh yeah. So this is like. There are first definitions of functions, then definitions of structs so that it returns.

B

So if you want to know like what what is ipfs get result, you can just do that and under record type. You will find the iphone get result and you will see that it's a structure with three fields, success, error and path and its types you can see as well.

So um I I guess list interfaces is now more or less obvious. It just shows all interfaces of all services that you created on this node yeah, as it says, as it says, lists all service interfaces on appear by a given opener and since it's a peer-to-peer, it could say on appear by a given peer, but that would be utterly confusing so and that cover covers all the major changes that we have. Let's take in aqua, cli yeah. So that's it from my side.

A

All right, very cool, thank you. Anybody have any final questions.

A

If something, if you think of something later hit us up in discord, ready to jump in or telegram for that matter, all right, uh one alex to go.

G

Yeah, that's me now. I want to present you some little demo for registry.

G

Let me give you some context. Service is essential part of affluence protocol and it's uh if you want to call some service, you need to know his coordinates like service id and peer id where it's hosted.

G

You can deploy. Services redeploy it, but it's handy to have some stability fire to find these services like in apns.

G

So for this we need some mutable registry uh which can be used for advertisement and service discovery and if uh where's, two types of services, uh one type is uh on full-featured rust, node and can be found only by uh pig of snot and service id and second is uh services. Andreas jaspers is not fully featured and to call some service from our peer on jsp.

G

You need to know relay uh to which this jsp is connected: solvers free part, free, unknown and parts that can change in runtime, so it will be handy to have some some registry to start with identifiers.

G

So I want to show how to register service on jsp and find it and call from another jsp.

G

Let's say we have greeting service that just accepts name and return strings like hi name, so, firstly, we need to register with service on our jsp.

G

This is default. Stop for jsp you can. It can be found on fluence, not just template, so, firstly, we need to register our service with some some service id like migrating service.

G

We register function to greetings that just locks the message and returns: a continuation of a high-end name.

G

So export files x bracket looks like this. It just import clicking service from our service file and export system typescript, and it's all compiling.

G

Okay: next, uh we need to advertise this service. uh uh If we wanna find this, you know if we wanna discover a service on our spirit. We need to know the road to the spear like relay id peer id and service id to call with service, so we need to create route and register for it.

G

Routing mp is and for such things, to to register roads and discover services.

G

So we import this function in expert aqua and.

G

And import it in our typescript file.

G

One second, oh I forget to export it.

G

G

So route have have a label and label unique for each peer id.

G

We can. You can use any possible string that you want and for each route. We have records records which represent providers of services on this road by this stabilifier, and we have some value in these records and you can use it as you want like it can be specified by business logic. We don't need it in this example, so we just uh put any string to it.

G

If you want to create addressed route, we pass label value, our relay id and service id of our registered service, and it creates road and records in the registry and replicated to a neighborhood, with information to discover with service like service id peer id of our freelance peer and service idea of our greeting service.

G

So we, this is our jsp. We scott needed to just wait and not exit, and we can run it.

G

Okay, we connected to fluence network with vsphere id to this relay, and this is our route id now route id is just inclination of label and our peer id as you see, but it's for debug purposes and later it changes to hashes, and now we need to from an appear discovery service and send our name for this. We need to have greeting function.

G

Whereas our greeting function, acquisition is a number of node which we want to uh to ask about. Our road and road id is route id from from this output.

G

So if you want to find all providers of this route with this services, we just ask: we just call routing api resolve route and go through providers and call with service on uh with peer id virus relay and resolve service id on with peer and calls greeting function.

G

Whereas our client, it's very simple, it just accepts route id and call greeting function. Let's try to call it.

G

Just copy robot id and.

G

Okay, it's eternal uh out to us hi alex say and as we see, we received our message in the service the server.

G

So it's demo about registering is about advertising and discovering services in jsp, but you can do the same with services on the node and whereas api in routing it's called the same, but with postfix node.

G

I can show you as well.

G

Yeah, it's create and register node and you can pass all all the things which passed in previous function, but you need to pass node id. So that's all.

A

Very cool, thank you. Anybody with any questions, I'm looking at you again.

F

Yeah, I have a lot of uh well today. I had a lot of questions. Some have somewhat been answered: okay,.

E

F

But I'm still uh confused um and that's not that's just gonna take a while before I start getting it um because I in my idea it's like a way to for other notes and peers to give permission to do something on their notes.

F

um And um well, that's the way, I'm thinking about it, maybe that's wrong, um so I you open a route that you create a route. Somebody creates a route with an idea of a task they want to be have performed and then um other notes or peers or well or appears they will say like okay, I want to I want to perform that task and then because they registered themselves to the route, then uh that function from the original peer can be run. That's how I see it. Maybe that's already wrong.

F

But um yet this this happens so fast that I'm wondering where is sort of the the permission from the um um the second pier. Where, where does the second pier say like.

F

I'm I'm also registering.

G

So document permissions uh now anyone can uh register for the road for road to now appear without checking permissions, but in the next iteration we will add uh trust graph to it and uh whereas crypto proofs, uh that can be checked, uh if we spear can register for this route or not and yeah. Now it's not mentioned, but it's planned and everything ready for it. So so now anyone can register road like uh tell somewhere advertise it, and everyone can register for this road and provide services, but no permission.

G

Checking like only signatures when whisper added to his record always registered with road.

F

Okay: okay, but um who provides the service the person that is registering or the person that created the route.

G

uh Okay route is just uh how to just route id and metadata of creator, and later it will contain challenge for permission. Checking for for route can register peers with records with service id peer id and real id and yeah. So service services can be hosted on jsps and peers, provided with services. All the services can be hosted on notes and provided by our nodes.

F

Okay, so create route and register here on line 22, I interpreted that as that I was creating a route and registering myself to it.

G

Yeah, that's true: okay, that's true! If it's create route and register not so it's will be advertised no service on uh rust, node.

F

Yeah uh yeah, so um this by now is working after I updated everything correctly uh and but I'm I'm having troubles with like registering another beer.

F

And the problem is that that this, the weight that is that should be gotten from this stress graph is not returning anything, but I'm gonna ask you about it tomorrow. On monday,.

G

It's strange because in uh for now trust graph, where there is no, there is no problem with trust graph because it's like not used at all but just get zero weights and put zero weights in registry. But, okay, you can touch me in influence, telegram, channel or discord.

F

Yeah I'll I'll bother with people with this tomorrow.

C

What what api do you use? Do you use this routing aqua, or do you use something directly like? Are you calling the registry service directly? uh No well, of course, you're.

F

Not expected to.

C

Do it and alexa.

F

Told me to only use uh the routing methods in routing well.

G

F

But when they fail, I start I I try to investigate where the where the problem is so then I use the the other ones.

C

F

C

You should follow the invariance uh tetraplat checking in variants, so you you have to query the truss graph on the same node to provide the weight. uh Otherwise it will not take this argument, so this relationship between the services is enforced by the tetrapods.

C

You cannot just put the number here. You cannot fake the weight.

F

um No but yeah: well, um let's yeah.

F

When I, uh when I uh return like the object that is created uh for the weight, that's like weight result or something, then it said this: it's an object with everything is undefined.

C

Super strange yeah: we should investigate it.

F

F

I'm going to ask about it tomorrow.

F

uh What else did I wrote some things down.

C

So this demo was about routing the requests to some service over the network and uh permission. Checking for this routing is a natural companion, that's cross graph, but it's not covered, but we are going to cover it hopefully into weeks, ideally hope so, but maybe in the month we'll do.

A

All right on that note, anybody have anything else. Anybody want to present something want to mention something. I want to ask a question.

A

Well, in that case, it's been awesome, seeing you all again and uh looking forward to see you in two weeks with uh hopefully a major update in the companion to uh registry and uh before we watch them terrorize the cat any further. I hope you're all a little bit more awake than a cat there, but other than that. It's been great. Thank you very much and I'll see you next well in two weeks cheers.

A

Thank you bye. Thank you. Bye.
