So this is the github page for Lotus, Jeff's, client and Lotus has an API. You can talk to over HTTP. The API is built around JSON RPC.

A

This is the format that goes over a wire when you're talking to your Lotus minor nodes and miners, and you can program it and go potentially any programming language, but we're making some libraries run on the JavaScript script or in your web browser or in no GS with JavaScript, which simplify talking to your Lotus Notes, and this is the github project, for it there's a little example code here and then, if you click down here, this is I'm. It's really under construction, but there's a documentation section.

A

This will turn into another site a little description of the list of libraries. I'm gonna have some QuickStart guides and I've also got not complete API documentation yet, but you can sort of click through here and see all the different methods you can call.

A

This is the go documentation that have got in here, but will replace it with examples that use the JavaScript library that I'm working on so for this demo, I've also running a local net with Lotus and I'm, using the Lotus file coin implementation and I'm using a project called test crown which lets you run networks of software and do testing and things against it and I'm using it to run a this is literally the code from like two hours ago, the tip of the tree of Lotus, which will be the next version of the test net and to demonstrate the library.

A

Earlier this week we did a workshop where I used this code code, playground called glitch and here's some source code I'm, just gonna go really quickly, but you can just click on show new window and here's the app I built it all the source codes there. And what it's done is it's connected to this, these six following nodes, I'm running and it picks one at random, and you can click here. You can see the chain. So this is a developer bill. A debug, build file.

A

Orion thinks a block out every two seconds: that's very quick sealing which normally takes hours only takes minutes, because it only allows you to soar store to thousand bytes at a time. You can see here, here's my my miners and they have power. So here's the demo so I'm going to open the camera.

A

There's me you call something else. So I can tell take picture so what it did. Is it just uploaded that picture is shrink it to under two thousand bytes and it just uploaded it to node number four in my network, it's sitting there I want to actually store it on file quite using Geils. So I've got these little buttons here.

A

I'm gonna store it on all the the miners here and if I scroll down, you can see it's going through the process of storing on file coin and you can see when it finally gets to the ceiling state. This takes one. This never takes maybe four or five minutes so we'll be able to complete it before the end of the thing. The thing but I can look at some previous ones, I've stored, so I can click on here. I can see on node number four Oh.

A

Actually that's the ones I just did I guess these are older and so I can copy the cid and then I have a retrieval client here. So I can put the cid in here find in download. So it's going to say o from mode number. Four I distorted on this minor. I click retrieve and hey. The demo. Gods are happy, so this is I stored. Previously I got Molly to volunteer and.

A

About ten minutes before she opened up a web browser and she she stored her selfie on the spot going network. So if this works, I should be able to steer achieve as JPEG I don't know, the demo gods are happy to eat now so hey there, this Molly so hey.

A

So if anybody wants see if they can actually go to this this this link here and then you go find a chat.

A

You can store your selfies and I. Don't know how this code, like I I, only got this written this morning, but the actual printed web print in and the loudest thing I just pulled it. The latest build. So it's really stabilizing it's good stuff and yeah. Try it I. You can try to post the see IDs in the chat, but you can't copy on a slack. So there you don't want to type them by hands anyways! That's what I got so um check out.

A

My library, I'm working on and we're gonna, do put a lot of code examples and show you how to build things like this. So thank you.
