A

No I think that no one no one's talking alright.

B

A

Fairness: okay, yeah, yeah, I, hear you. No sorry, I didn't know that mutated. Okay, it's alright, so agenda very important. We are going to fix the 2020, a temporary schema, and this is the last time I collect feedback on this and there's some changes as well. All most of the stuff was previously confirmed in previous meetings. We are still open to suggestions and at this moment, but do it really quickly and I have to go through this with Boone and besides getting feedback?

A

I have to go through this with Boone and James Brown, and very carefully to make sure everything is implementable.

A

Here is a quick link to the to the file that is I have a changed and in order to be compatible with the February schema, and here it is- and unfortunately we didn't include attestation in schema, but we did include remember that that object in so have a look at the link and let's go straight to to the first change and line 27.

A

Everybody here, how are you there?

A

Yes and the Boone?

A

We are looking at line 27 right, yes, correct, okay, sync up, okay, good, so I, previously I mentioned that we are using ASM dot, X module as a schema language for data objects and I explained that data objects are used as for attestations, as well as for describing events, and we probably even use it to describe function course, but we will see about that later and then the this is the the data component of an token script and what you see from line 27 to line 35 is slightly modified from the previous content that we shared for you guys to discuss so um yeah.

A

This is an I think it's evident with what it means here. Note that when you define that object, you don't define how it has been used. Instead, it's the usage that is relevant. So let's say this data object: twenty nine, twenty seven to 20 30 35 later. If we have attestation, it will simply refer to this data object and then with the additional information about who who are the right for people to sign it.

A

For example, if we use this data object as an event, look at line line, 120 140, where the event is is is referred to. The object is referred to as an event.

A

That's the moment when it is used as a event, and if you look at 140 future, we discuss it before select to discuss it before that means which, which component to select from the event for the match for the events that matches the future- and we also, we also explained before 138, distinctly equal to true, which means if there are distinct values to be obtained from this origin.

A

Then these distinct values means that the user have distinct tokens identified by this attribute and the way we identify token is going to be similar to our DN, which is an key value pair. So for e rc, seven to one the key value pair would be token. Id equals two token ID and in in this case, and because they don't use er, say seven to one. The way to identify token is named equal to the name, as we will define define here, and there are as many such tokens as there are many names.

A

Are the for illness that is equals to? We got us and.

A

So this is how internally we store tokens in in agents in the user agents, and this is the this is basically a recap of a previous discussion. If you have any feedback, yeah that's this is last time we check it back in yeah and open for questions, then after this run that were introduced. The second change- if this is the first change that we introduced, that object.

A

Any question or not at all.

C

So the Select attribute in 9 1 4 0, just to let us let the user agent know that we should retrieve the value which is women s, and that is the value of the attribute.

A

So so, ok, let me first, you can label and first sorry, this future is actually wrong. Sorry, this filter should be the the owner equals to owner I. Don't know why it's wrong yeah, because I copy the code from James and garlic. Sorry, it's not the based on the version. I showed you, so the future is wrong. The correct future is owner equals to owner.

A

Which means of all the events on this contract Oh, which means for all the events on this contract?

A

First, you go through them and find those that the sales owner is you and then second, you, you get this list of objects and your select name name component from it, and that is the value for the key name.

A

For that tribute name, no okay and there's a piece election which I forgot to include sorry I would do this right after the meeting there's a dis election, which means for the four tokens that was transferred away from you, where the original owners you and the new owner is not. These are not selected.

A

So so so, there's negation to this, which I included in previous one. But this this version, I'm merging my work with James and galleys and I forgot to copy that over yeah.

A

Okay, okay and the is there any any other feedback can I just go to the second.

A

You think this would work like Blackpool. This is a this is the version that he is going to be implemented. I think we have that way. I went through this 33 in three meetings. This is, should be last one, so yeah. This is going to be committed as an implementable thing and we're going to robot release about it. So the background of this is we're going to roll out three releases for the event support the first one being this one and the second one being activities and the third one being notifications.

C

So the design of this assumes that at least four mobile devices that the server which can provide.

C

A

Yes, yes, I did I share this picture with you guys before. Let me do this on the channel sure I'll, damn it I, probably didn't shade before with you, I shared it to Sangha as an galley but and he's not here today and and and I forgot, that I had by sharing to him doesn't mean that many share to you guys so do I show you stuff with okay, maybe presentation mode.

A

Presenting tired to stop maybe.

A

Okay, so when we say there are three projects, one is support, ENS and the new and the February schema, and secondly, to support a notification. Sorry activities and third is to support notification. So here is the chart how it works, have a look- and let me know if it makes sense for you.

C

So step one preparation: that's only setting up the database with no events, no data are you yeah.

A

Basically, the generates a list of attributes and the events dependency table.

C

C

In debt events isn't determined token attributes to update, isn't that part of preparation.

A

Sorry no question again: I'm.

C

In one get events mm-hmm, you have, the second line is determined token attributes to update. Yes, should that be part of preparation.

A

Because you cannot yeah, actually it is already there.

A

A

Basically, the concept is, the wallet actually wants to know if it should generate any activities or update any views, and we assume that the the oh.

A

Yes, actually get events.

A

Okay, let me then use it. You change the language, okay, okay,.

A

Now, that's a clearer make sense. Now.

C

Yes, okay, so to test my understanding is correct. So is it correct that in theory, I don't have to so I don't have to subscribe to events instead, I can manually pull the server for the list of events in.

A

The first place- yes, oh.

C

A

Wait in the first phase, you still need to get an list of events following the future. So yeah you actually need the server. So sorry, sorry, a question again: yeah I'm, sorry, explain understanding again. Yes,.

C

So there are two sources of events: one is to get released from the server and from.

A

After filter right.

C

If the server provides a way to filter, yes,.

A

Otherwise, it doesn't make sense think about cryptic yes, less than point zero zero. One percent of all that is relevant to you, yeah, yes,.

C

And the second source of events is to subscribe to a node onto an API like emerita, so yeah my test was so in theory. We can support, we can add event support by just using the server and not connecting to a node or emulator.

A

So when you, when you have to connect node in the end in the third step in this area in the next step, otherwise you don't update the 30 attributes, otherwise they don't get to update 30 attributes. So me in the in the get event stage, you don't need known right.

C

A

Okay, now I modified, it make sense. Yes,.

C

But the order is actually wrong. You have to connect to the node first before the index database. Otherwise there might be a gap.

A

The reason you've got well wait a moment if you don't know what what actually is a. Thirdly, why do you go to know the first.

C

I presume that when you go when you, when you connect to the node, you have to specify some kind of the filter and you listen right. So as new events are triggered, oh listen! No, we will pick it up so.

A

So I don't know if the node would provide that function when I say no typically I mean just node. Is a node.

C

Yes but but but we have to get events as they are trigger.

A

That I, don't remember, node is able to do that, but even if it does- and it would be not practical now you have to get updated notes from the indexed server and although it might not be as immediate as the node, but if you connect a node and subscribe to the event, you get too much noise because the node is no one not to be able to future.

B

Yes, okay, like yes, you do get a lot of events, but you just saw through those self.

A

Computer, let's say crypto kitty. That means in one month, I will have 2 gigabytes of data and probably I don't have a single one of them really relevant to me, especially if a theorem has this problem that every time there's one hot project and the whole transaction is about that hot project. Everybody doesn't is it, it said to it, participate to it. The the filter not on the service be bad.

B

Ok, then, that we have new media, that we run ourselves and.

A

The index is room where we, as you mean there, is a way to get events by a server a future either we have to write it all. We have to use the existing service. Sure.

B

A

B

That's for them that's what Trust we're doing with their intermediaries to an extent I'm, seeing no, not to this extent. Yes,.

A

So they were turning to and yes, and if we only provide future in itself like providing future and capacity, it shouldn't be hard to go together anyway, like there are some I. Imagine that there's any any any theorem software that analyzes that I already have this function. It's.

B

Possible here but I mean you can even even if not and it's not it's not a complicated task to provide them. No.

A

So so the design yeah, so the so in terms of design I think the bottom line. Is we don't filter it on client side, it's not reliable either I mean there's many ways to make sure that the process actually running on Android, but you don't get 100% sure and you have to you know, recap between the time that service is not listening. Yeah.

B

Of course, and.

A

The user entered the kernel and then, when the user gets out to turn on tcp/ip connection turns out. They have to use article. It's just not reliable, I mean.

B

There is, there are some known protocols that allow you to catch up, so basically you can listen. You can subscribe to events and then, if you lose the connection or you know your your phone's offline or something when it comes back online again, you can catch up. Yeah.

A

That is a message.

B

Coming? Yes, yes, but.

A

Message queue should be placed to the front, not the back. That is you, don't use a message, queue to get all that and amputate your future and Daniel's message: queue yeah.

B

A

It's just like if we use that technology and and the forgo filtering it's just the right, I think yeah.

B

Well, I mean that's, that's the idea architecture and if we can get that where we are filtering server side, then that's better. It.

A

Will simply be like something we build and discard it, because too many people complain pretty simply like you are sending like overnight. You are sending 300 megabytes without huh and then he passed out really like drilling down and find. This is a problem and they were fixing the film. ah It doesn't make sense to write code to be discarded, we're already like a peon in experimentation stage. Yes,.

B

Well, providing we don't mind running another server and a solution again.

A

So we went, we talked about this three weeks ago that whether or not we have to do a server actually more than three weeks ago, and we really don't want to in put a server there. Unless there's a.

B

A

Reason to do that, so you know that I'm, a server of the version guy so yeah sure, okay,.

B

A

You very much James for joining. So is the picture making sense to you like, for example, when I say that market data dirty, you know what I mean here right. Yes,.

B

I know you talk, it's like an outdated data, yeah yeah at the moment, I think both on both what me and Boone are doing is just like I'm, polling or and well intelligently, polling like I'm. What I do is if it if a new transaction appears on the contract, then assume that all all data is dirty and refresh, but that's going to get strictly impractical. I'm, on my say, something like kitchens yeah.

A

And then make sure that the real is reliable is a lot a lot of work too yeah.

B

Yeah for sure yeah, so the um it's good to use much better yeah.

A

Okay, so so Boone just keep shooting questions every time you showed a question. I find a better way to explain. Ok,.

A

James Brown just to bring you back to the to the changes we just discussed its before, between from line 27 to align, 35.

A

Can you see the the okay.

B

A

Section so what it does is, and it describes the data module and with the X which is already RFC, then this data module is later used in 140 as event, which means the event is sourcing data from that one. The future is run. The correct future is owner equals to owner. This is wrong, our updated, so what it does is it gets all the events whose own there is owner, and then you get a lot of events right. Okay,.

B

Go back to the uncommon urban version.

A

This name is selected from this name. Select name means select from this event and get the name element and again distinct means that the this at the number of this attribute this case, the number of tokens.

A

And internally, it is stored as this did you see this James internally, a tokens identifier is like this like a today's identifier is attribute to key value.

A

This than token ID, because if this guy is not using ER since M to 1, there is no token ID, just like in the case where the NS, okay yeah, so basically the whatever you do, whatever talking aboot, if you want to identify, it is usually identified by kimahri. Okay, no matter how do.

B

A

Use this generic structure, then we should be able to capture all this, be aware of some strange guys who decided to build our D and with multiple key here. So that's something. We cannot control, because somebody can divide the new smart contract and simply say every token is identified by true key value. Pairs.

B

Could be two dimensional array.

A

That could be a that would be identifier a token. The problem is that we cannot and we cannot restrict this design, because whoever right took a script, Robert write us up into a smart contract. He might not have a perfect way of organizing it in mind and the tauren ization work might come after it, so you have to somehow yeah. So this is this is possible. So just be careful when you store the token identifier, it's actually a list of key values are.

C

You are you typing, in a small, smaller window, yeah.

B

C

See what you're typing? Yes, that small window? Okay! It's that one.

A

But that window, you should be able to see it anyway right. It's a chat, room.

A

New crypto dog and it's not like crypto key.

A

Like a sari goes to my name that could be object. Identifier, I.

A

Don't know why would someone design things like that, but it's not under our control, so when you internally store opt-ins and start that as a key value, pair or sequence of key value pair.

A

Because people are some people, sometimes people use multi, multi kid database table as well. You know just to be careful so back to this one, so this line history lines defines how many tokens, how many tokens you ever have so be careful that sometimes a new event created, which means you don't mark a name as dirty. Instead, you create a new name, because that event could mean the user had registered a new name.

A

So just to be just to be precise here. Mark there should be is, depending on the events.

A

A

Okay, good, so then, and so is this okay, if this is okay now well, could change interchange.

B

These changes you're making this.

A

Is exemple- and this is a schema validated example, which means yeah. It's close to production, okay,.

B

A

A

Nice now the second change is related to how views are presented. So this is the new new way to do views so having observed James and golly working on views, it turns out that usually this view is not into camera, but there's only one thing which is JavaScript in it, so I think it's probably probably better to do this. Do it in this way every view has a component style and component script and there's no accelerator at all.

A

The concept is and because the concept behind it is because token views were supposed to be updated as token gets updated, its Tamara as a static representation wouldn't work anyway. We either need a template language, but we need something similar to react. The JavaScript framework for updating objects either way the code is going to be either a template language which can be JavaScript or that it's a JavaScript in react native. Therefore, there is no correct, so there's there's no way to there's no need for schema and also it reduces trouble invalidation.

A

A

By this changer, this one, that is every every view, should have a container HTML element that you need. You uniquely identifies it currently. James and golly would always wrap everything inside a view with a div element HTML. You know whose ID is root, and this has to change, because we cannot dictate the implementation. It can be happened that token script is rendered in the context that already have a root of you.

A

Imagine, for example, you render a list of activities in that tivities tab and instead of and let's say, the user have about a hundred activities instead of producing 100 web views, you produce a single word view and inside of which there are the activity items I quantified activities, one after the other then certainly cannot wrap everyone. If the div ID equals the root, because then the ID is not only unique that does that make sense.

C

Yes, but in our implementation we don't we don't access the deef with ID.

A

There are loads of JavaScript in the currently written token script by jin-sang golly. That does the document to get element by ID root.

A

Yes, but that's within the page itself, but you don't know if the pages is in the count inside another bigger container, which has lots of other routes all right. So if he had.

C

Called branch instead, ID was a branch he just has to change his own JavaScript code to refer to branch instead of any work. The token sweet client doesn't rely on whether he's in call duty or doesn't care.

A

Let's take the story to the context of a web okay. So let's say this is a web page, okay, actually even without going to the web. If we, even if we just go talk about activities, it would already be a problem. The the the the user, the developer likes and golly we'll put a root, a div around every activity, which means you practically cannot render list of activities in one webview. I, don't understand! Why, like you, just spoke as if you're not getting the gating the problem, but I, don't follow your logic. Okay,.

C

So you're saying to put it in one single webview, yeah.

A

And it's not avoidable, because we cannot guarantee that we will be able to produce token script running in in webassembly anytime soon. So imagine that a token being revered when rendered in the web web interface, for example, Carnac story. The story often tell about. Let's say this is website called car next door and you can list our cars for rental and you can earn $100 per day. The webpage would have a section where it is it the cars you know, logo and color being displayed, which is a token of you.

A

Imagine that being a being the TV box on web page. Ideally, it should be rendered separately, not inside a web page, but we cannot. We cannot be sure so when you put it there and it have a div, the div ID equals root. There is really good chance that you're conflicting with other container objects, and if you are able to list a tool of your cars to be rented, it's guaranteed conflict.

C

Yes and it's my fault because I wrote the original versions copy, the is. Am I right to say that the best thing, the only thing we can do is we change it to a class instead of ID. Well,.

A

So the first you cannot get a get ID by class and then, if you, if you they're the best way to do that, is simply to provide a document, a route document as Dom object in API.

A

We can't give it a special ID, for example, a token ID equals to something strange. We can do that, but I really think that the best way to do that is have a have it in JavaScript API. That is, you can simply get the root view. The root of the view.

A

Okay, so we can do both. For example, we can always create a top-level container, which is called div ID, equals to token ID equal to something you know really long stuff. We cannot use the character equal, but you care what I mean here in the meanwhile, we provide the JavaScript API and the DME top-level container is hidden.

A

We don't tell anyone about it, but we can use that if we find it convenient to us- and we actually published in the document that the correct way to get the container is to use a container function or something like that. But.

C

This is not the only change that we have to make. We also have to change how the property called current instance is, is used.

A

Can you tell me what a property, the the the name of the guy this web.

C

Three-Door tokens store data dot current instance.

A

Yes, yes, so so the logic is previously. We find that is necessary to get and other instances. So we just put it into current inst instance and then expect in the future. There are wastes expanding to other instances right. Oh.

A

Yeah, that's better! That's the future version that if you want to access other instances.

C

Of the token yes, but by by exposing dot current instance, we will have the same problem which you describe because can't.

A

C

Only refers to the current instance, so if you have three two of them, they were all point to the same. One now.

A

C

So if we can somehow make dot current instance, work like maybe, is an Iranian state and develop a stupid. The thinking stuff route ID inside.

A

Yeah this and that's the said: if you're right.

A

Okay, so that's that's the issue and that issues impact is slightly different, because imagine this imagine that you have them.

A

Imagine that you have a token script running in not on the webpage. This would affect. If the token script runs on the webpage. Imagine you have every token script not running on the webpage. Instead, it rents in the meta mask a little bit like the tablet concept. You know buddy's a magician which is an and an imagine he's been there. Then we cannot.

A

We cannot use.

A

We don't know if there's only one route in the u.s. Vol. However, actually your problem still sits. You're right. The problems do exist even in even even the droplet mm. Actually.

C

Maybe I'm wrong, so imagine if we invent a way to generate the unique route ID like you described and we add it as a property with inside current instance, when the way we currently trigger an update is we involve data change function and is responsible for using that as installing a callback for that fresh rerender.

C

So so imagine if you have three tokens or activities right, we just have to fire. Those three differently is one of them. Changing we just fire one of them rather than a global one for three. Yes,.

A

Sounds reasonable, would you be able to write it down and, as today, I will finish the meeting minutes and that were published a community post will be able to follow up with this detail so that we go down this and a short pitch, and then we can go with it by the way. Yes, please no go on.

A

Okay by the way, I know that we don't know what template language will be there, that choice in the future, but I think that in general the concept is, you have some language so having removed HTML and instead play put script script they're, always at new kite new types of script, so this change can be made even if we are not 100% sure about the future template language. One one thought about that: oh, if.

C

Only only was saying that we won ways to let developers use something like react, but as part of react, they might still include HTML. Yes,.

A

I know but having HTML is also creating trouble unless we have a way to use object reference, which is something we cannot do right now, because I don't know if the library is are strong enough to test this object reference integrity, the the we simply ask them to change their behavior, the HTML being included inside XML is not a very good idea, is better being referred to as object I.

A

C

One part about this problem: I, don't understand, what's wrong, we're stuffing it in C data.

A

Actually, we can do that. He's Justin, you mean XML tags, yeah, yeah,.

A

It's probably something like this.

A

Yeah, it can work.

C

Is there any limitation to what can be in C data, because.

C

A

Problem is, you cannot have it inside sadena, so that means, if you have sitted, then it cannot have a piece of JavaScript which inside has a C data inside.

A

Happen: I don't know yes,.

C

Sounds like a reasonable limitation.

A

Can we put in this way like so because we are not providing a whole HTML? You know, because this is just a view and then we have to supply the style anyway.

A

Therefore, scripts can have their own C data.

C

C

A

At least this way we will know that we would not cry if we have made a big mistake, because there's always a fallback method to use can entity references. Well, this it would work, but I really want to use object reference for this, not entity reference, but that's something later because object reference allows you to store the object outside of the XML file, and it is you know inside.

A

So imagine that you have an token script that has a video. Then you certainly want the video to float on YouTube or somewhere as long as the integrity is guaranteed, which is the you video downloads at certain matches, certain hash. How may be ipfs, you know, so it's better to use object, but I just wanted to move one step at a time.

B

Okay, just just remember that references are don't work on Android just so that I'm like if you, if you compile the script to the end and it'll work, but um any kind of object- reference, that's not compiled out we'll just that script will fail on Android yeah.

A

That's why we're not supporting object reference, because you have to define the process of actually fetching it from somewhere and check the.

B

A

B

A

That sounds like a lot of work to do, and although it's in the XML signature, spec I'm not sure if every library implemented correctly, I need to do some experiment, experiments and I'm sure that these libraries don't know how to fetch it from IVFs.

A

So yeah there has to be callbacks to how to fetch these objects yeah. So.

A

Okay, so that's um that's a change and I James. Are you ok with this final addition with the script, just style, script and content altogether.

B

B

It's alright, providing that we can run it through the make file and basically developers won't be able to and won't be able to use any of this stuff. If they're developing an Android yeah.

A

Yeah so basically everything reason to the so so everything but he's.

C

No worse than what we had currently yeah.

B

For sure yeah I'm, just saying this is something just to be aware, but.

C

There's an advantage because, because is in see data, then you can just put in your ambitions, etc.

A

Yeah yeah yeah.

A

That's about right, yeah! It's not elegant, though, because in JavaScript starting will see a doctor. Yes, fire starting will see that and that's really ugly, you you it's best to use a reference, but then I don't want to start another to struggle with the reference stuff. It better be done in a separate project where we claim support of IP address. You know, okay, so that's all the changes, there's one tiny change, which is an inside cards.

A

You cannot see it here, but inside cards previously there's a token card now we change it to token without that card, so get cards inside carthoris token. Previously I was considered concerned that if you have a token element inside cards- and it would, it would be called the same name as the line 9 where the roots element is, and maybe people would be confused because the elements have the same name, but it seems nobody was. It was confused and with this kind of thing and so I just you know, change it back cards here.

A

Imagine this being action instead of action being the token yeah. This last change.

A

Okay, okay, so yeah! So so that's all and there's also 25 minutes already so yeah guys. If it's okay, I will publish a meter review and that will be marked as increment but implementable. Okay,.

B

A

If I'm, not okay, tell me.

C

What was the so, what's the school of the project.

It's an okay, so you need to support a new schema. You need to be able to build index database of events and you need to be able to gauge the value of attributes and somebody has to make the server so the activities tab, there's there's not in the school. No, that's the second phase. Look at this! This picture has a first phase. You know: can you see my selection box? Yes, this is the first phase.

A

On the surface, it only allows you to support ENS just that today, I'm the user, there's only one thing you are now able to support in this and second place is here. Can you see this.

A

Yes, it's not fair because much of things is being defined, but there's a separate a three-page for that- and third third is here, which is getting notification running.

C

So the first phase also includes being able to.

C

C

Tokens based on events, in the token sweet view, yes,.

A

Okay, that is the number of tokens determined by the number of token identifiers, which is determined by events.

C

Okay, since we are talking about yen s, if we identify that, if we have a token sweet file and is for holding contract, which is also observed in the results we get from open sea, do we just completely drop open sea? For that token, that contract and.

A

Yes previously, there was a item. Sangani was has argument. Well why? We should not do so, because open sea has the potential for getting us to know how many sub tokens we have but and I. My argument against. That is, if you know how many sub tokens you have, but you cannot see them in clear text, then it's as useful as if they don't have them so I mean having often see displaying the list of subtotals. That does doesn't mysteriously identify the bad hash and doesn't give you very much.

A

We can probably just display the number of sub sub sub tokens instead. So if we can display the number of sub tokens, we can drop the open sea okay. So you know what I mean here: there's a problem in the S contract that the open sea cannot obtain the sub domain list and there's no way to obtain that list.

A

You, you have to know it by yourself, as a user, so I often see instead resorted to display the Sabbath House domains just use the hash, which is confusing and I said that is as useful as just displaying the total amount of them.

A

Okay yeah, which means that we are going to display only the yes domains you have and how many subdomains you have under it, and then that's that's it and then, with that with those we probably can drop I think we can drop open, see.

A

Okay on this only on the is only.

A

Yeah, okay, yep! So so far, so good to everybody that all right and all.

B

Right here, I can see: okay.

C

Okay, oh, oh sorry, one one. Hopefully last question: okay, which networks? Are we going to support change, test Nets minutes so.

A

So I hope we can find the source of an indexing here me event database for everyone, but it's a really good question what you do to do if a a one of the blocks I'm.

B

Going to support some main that wimpy and.

A

B

A

The client well.

B

What we could do is we could run our own notes, which are only being used for an event lessly, and if we don't have event listening, then we have to fall back on previous ways of working at events. Maybe I.

A

Don't I don't like to have the code base and having two sets of logic, that's growing in a code base which makes it very difficult to maintain and I I prefer to do this. If, if a, if there is no indexed event source for a theorem block chain or a theorem like block chain, then we simply display, then we simply never update the the actually builds unless the user. Explicitly, though so, okay.

B

Yeah so there's basically a refresh button or something like that: yeah, okay,.

A

Activity is kind of empty and accepted the basic key theorem transactions. I'm just explain to the user that we don't have the event sauce for this one, so yeah, okay,.

B

Yes seems reasonable.

A

I can ask the whole time I could produce something like a mark where the user can click and see, sorry that this is not up to date, because yeah.

B

Because it's testing it because it's test net, it should be you know- should be fine. Okay minded.

C

These effects, but the car yeah.

A

That I was thinking about better car to I, have with him to produce our own indexed event database for battle card Chinese. How do we know it's need an? Actually. You can argue it's not needed, but if really scalable solution you don't want to. You know. You know there are loads of event. Coming from the single contract running on the battery card.

A

Is your blockchain there's only one contract running there and we subscribing to all the events and soft a future means it basically subscribe to everything happens on the and the on the Easter and that production, it's just not scalable. So it's better way to do. That is to find a way to make index key theorem database server source code that is available for for download in our own, with our own honor that we can convince a member that had to connect to a better card or.

B

We could talk on tobacco and get them to run a server similar to the one that and we can be putting together.

A

Some research has to be done on what kind of server to rent which will move that we will do. Yeah, okay, yeah I, don't like to have the idea of having the event by event, server based a solution and the polling solution. At the same time, better display it has style and ask user to refresh yeah.

B

Make sense yeah.

A

Complex I imagine the code would be too complex.

C

Thank you. Thank you.

A

C

A

Produced a little minute and you come up with a JavaScript API note and that's ready to go. Okay.
