How to Build a Secure and Decentralized Blog Website on the Blockchain

Β· 11 min read


Introduction​

Beyond cryptocurrencies, Blockchain technology offers tools to build secure, transparent applications fully controlled by the user. Building a blog website on the blockchain allows the user to establish a censorship resistant space where they retain full ownership of their content and data.

In this article, we will look at how to create and host your blog website on the blockchain using Juno. Juno is an open-source Blockchain-as-a-service platform that offers a fully decentralized and secure infrastructure for your applications. This article will cover setting up a boilerplate project, configuring the hosting, developing the code for your blog and deploying the project on the blockchain using some of Juno's super powers.

By the end of this article, you will have an understanding of how Juno works, how to host your websites on the blockchain and how to automate the different tasks using Github Actions.


Prerequisites​

  • Prior knowledge of working with HTML, CSS and JavaScript
  • Prior knowledge of working with terminal or command line
  • Prior knowledge of Github

To follow along this article, you dont need any knowledge about crypto and blockchain


What is Juno?​

Juno works just like traditional serverless platforms such as Google Firebase or AWS Amplify, but with one key difference: everything on Juno runs on the blockchain. This means that you get a fully decentralized and secure infrastructure for your applications, which is pretty cool if you ask me.

Behind the scenes, Juno uses the Internet Computer blockchain network and infrastructure to launch what we call a β€œSatellite” for each project you build. A Satellite is essentially a smart contract on steroids that contains your entire app. From its assets provided on the web (such as JavaScript, HTML, and image files) to its state saved in a super simple database, file storage, and authentication, each Satellite controlled solely by you contains everything it needs to run smoothly.


What is ICP?​

The Internet Computer (ICP) is a blockchain-based platform that aims to create a new type of internet, one that is decentralized, secure, and scalable. Developed, among others, by the DFINITY Foundation, the Internet Computer is designed to serve as a global public compute infrastructure, allowing developers to build and deploy decentralized applications (dApps) and services directly on the blockchain.

Unlike traditional blockchains, the Internet Computer uses a unique consensus mechanism called Threshold Relay, which allows it to achieve high transaction throughput and low latency. The platform is also designed to be highly scalable, with the ability to add more nodes and increase its computing power as demand grows. This makes the Internet Computer a promising platform for building a wide range of decentralized applications, from social media and e-commerce to finance and cloud computing. Learn more about ICP


About the Project​

This is a secure and decentralized blog website. The frontend is build with Astro, which is a modern, flexible web framework focused on building fast, content-rich websites with minimal JavaScript. Here is what you will build by the end of thi article:

Setting up the project​

In this section, we will look at how to create a boilerplate template for our project.

In your terminal, run the command below

npm create juno@latest -- --template astro-starter

In the prompts;

  • Provide the name of the project folder myBlog
  • Select yes to configure Github Actions
  • Select no to configure the local development emurator
  • Select yes to install the dependencies
  • Select yes to install juno's CLI tool. Juno CLI will help us to deploy our project in the satellite.

Navigate to the project folder myBlog and open it in your favorite code editor. If every previous step is successfull, running npm run dev will open the project in your browser and you should have something similar to this.

This file holds our sample article data that we are using for this project.

If all the above steps are successfull, your project should look like this in the browser

local project


Deployment​

In this section, we will look at how to deploy our project live.

Creating a satellite​

We need to create a satellite that will host our project. Follow the steps below to create your own satellite.

juno statellite

  • Navigate to the administration console website
  • Login with your internet Identity
  • On the dashboard, select Launch new satellite
  • Provide name myBlogSatellite for the satellite.
  • Click Create Satellite
tip

To keep the satellite operational, the developer pays a small fee that is used to purchase the necessary cycles for the satellite's storage and computation requirements. Learn more about pricing


Connect Project to the Satellite​

We need to link our project to the satellite. follow the steps below

In the project terminal, run the command juno init and follow the prompts

  • Select yes to login and authorize the terminal to access your satellite in your browser

  • Select myBlogSatellite as the satellite to connect the project to

  • Select dist as the location of the compiled app files

  • Select TypeScript as the configuration file format.

If the above step is successful, a new file juno.config.ts will be added at the root of our project folder. It contains the configuration necessary for our poject to connect to the satellite. You need this file if your project is to be deployed successfully to the satellite. Learn more about this configuration

Compiling and deploying the Project​

Now that we connected our project to the satellite, we have to compile and deploy project to the satellite

npm run build

The above command compiles our project and outputs the compiled files in the dist folder

juno deploy

This will deploy our compiled files to the satellite that we connected linked our project to.

At this stage, if all the previous steps are successful, juno deploy command will output a link whixh is in this format https://<SATELLITE_ID>.icp0.io where SATELLITE_ID is the id of the satellite that we connected our project to.

tip

Running juno open in your terminal opens your project in your favorite browser.

Opening the link in the browser, you should have something like this below live project

If you have reached this step, well done, you have successfully deployed your first blog website on the blockchain using Juno.


Setting up Github Actions​

If you noticed in the previous steps, every time we make changes to our project, we have to manually run the commands that compile and deploy our code to the satellite. But in this section, we will learn how to automate these tasks using Gihtub Actions so that whenever we make changes to our project, these changes are automatically deployed to oour satellite

In our project, we have a folder .github which contains the file deploy.yaml. This file has all the configurations required to setup Github Actions in our project. This folder must be present in your poject to successfully setup Github Actions. You can add it manually if you dont have it in your project. Below are the contents of the deploy.yaml file

name: Deploy to Juno

on:
push:
branches: [main]

jobs:
build:
runs-on: ubuntu-latest
steps:
- name: Check out the repo
uses: actions/checkout@v3

- uses: actions/setup-node@v3
with:
node-version: "20.x"
registry-url: "https://registry.npmjs.org"

- name: Install Dependencies
run: npm ci

- name: Build
run: npm run build

- name: Deploy to Juno
uses: junobuild/juno-action@main
with:
args: deploy
env:
JUNO_TOKEN: ${{ secrets.JUNO_TOKEN }}

Generating a secret token from the juno console​

To set up Github Actions, we need a secret token that uniquely identifies our satellite. Github needs this secret token to associate our repo to the satellite.

  • Visit juno console, and select myBlogSatellite satellite.
  • Under the controllers tab, click add controller
  • Select 'Genetate new controller' and select 'Read-write' as the scope.
  • Click submit. Once the new controller is generated, it will provide a secret token, copy and store the secret token. secret token

Setting up Github Repo​

On your Github account, create a new repo and name it myfirstBlog.

  • On the settings tab, navigate to Secrets and variables and click Actions.
  • Click on the new repository secret, add JUNO_TOKEN as the name, paste the secret token you copied from the juno console in the Secret section.
  • Click Add secret.

github repo

Pushing Code to Github​

To upload our code to our remote GitHub repository, we must establish a connection between our local project and the repository

Run the command below in your project terminal

git init
git remote add origin https://github.com/sam-thetutor/myfirstBlog.git
git add .
git commit -m "my first commit"
git push -u origin main

The above code established the required connection to our remote Github repo, and pushes all our project code to that repo.Now every time we make changes to our project, all we have to do is push these changes to our github repo and they will be deployed to our satellite automatically. Learn more about setting up Github Actions with Juno


Next Steps​

Now that we have successfully hosted our blog website on the blockchain, you can go ahead and add more articles to the blog to showcase your skills. You can also add more features on the website to make it more robust.


Conclusion​

In this article, we have looked at how to create a boilerplate template project using juno, how to create a satellite from the juno console, writing code for our project, how to connect the satellite to the our local project, deploying our project to the satellite and configuring Github Actions to automate compiling and deployment tasks for our project

Unleashing the Infinite with Serverless

Β· 8 min read


Hey there πŸ‘‹,

Are you looking to extend Juno's features? Stop right there, because it is now possible!

I'm thrilled to unveil today's new addition to the set of features offered by Juno: the introduction of serverless Functions enabling developers to extend the native capabilities of Satellites. This groundbreaking update opens a plethora of opportunities for developers to innovate and customize their applications like never before.


What Are Serverless Blockchain Functions?​

In the realm of cloud computing, serverless architecture allows developers to build and run applications and services without the burden of managing infrastructure. This model enables the execution of server-side code based on user demand, allowing for direct interactions with APIs, databases, and other resources as part of your project's deployment. It's a paradigm that significantly reduces overhead and increases the agility of software development processes.

The introduction of serverless blockchain functions by Juno innovatively takes this concept a step further by integrating blockchain technology into this flexible and efficient framework. This groundbreaking development opens the door for extending the native capabilities of Satellites smart contracts, pushing the boundaries of what's possible within the blockchain space.

This means you can now enhance the functionality of Satellites smart contracts and extend those capabilities with anything that can be achieved on the Internet Computer blockchain.


How Does It Work?​

At the core of Juno's serverless blockchain functions are hooks, which are essentially the backbone of how these functions operate within the ecosystem. These hooks are defined to automatically respond to event triggers related within your Satellite, including operations such as creating, updating, and deleting to documents and assets.

An essential feature of these optional hooks is their ability to spawn asynchronously, a design choice that significantly enhances the efficiency and responsiveness of applications built on Juno. This asynchronous spawning means that the hooks do not block or delay the execution of calls and responses between your client-side decentralized application (dApp) and the smart contract.

A picture is worth a thousand words, so here is a simplified schematic representation of a hook that is triggered when a document is set:


Getting Started​

In addition to unveiling this new feature, we're also excited to introduce a brand-new developer experience we hope you're going to enjoy. This is built on the local development environment we released earlier this year, designed to make your work with Juno smoother and more intuitive.

note

Make sure you have Juno's CLI tool installed on your machine.

Start by ejecting the Satellite within your project. This step prepares your project for local development. Open your terminal and run:

juno dev eject

In a new terminal window, kick off the local development environment that leverages Docker:

juno dev start

Now, your local development environment is up and running, ready for you to start coding.

Once you're ready to see your changes in action, compile your code:

juno dev build

One of the key benefits of Juno's local development environment is its support for hot reloading. This feature automatically detects changes to your code and deploys them in the local environment. It means you can immediately test your custom code locally, ensuring a fast and efficient development cycle.


Demonstrating Hooks and Data Operations​

This sample application illustrates the use of Juno's serverless functions to perform asynchronous data operations with a small frontend client and backend hook setup.

The frontend client is designed to save a document in the Datastore, while the backend hook modifies this document upon being triggered. This process exemplifies the asynchronous capability of functions to read from and write to the Datastore.

Getting the Sample​

To begin exploring this functionality, clone the example repository and prepare the environment with the following commands:

git clone https://github.com/junobuild/examples
cd rust/hooks
npm ci

After setting up the project, to start and debug the sample in your local environment, please follow the steps as outlined in the previous chapter Getting Started.

Hook Implementation Details​

The core of this sample is the hook code, which is triggered upon the document set operation in a specific collection. Here’s the hook's logic:

#[on_set_doc(collections = ["demo"])]
async fn on_set_doc(context: OnSetDocContext) -> Result<(), String> {
// Decode the new data saved in the Datastore
let mut data: Person = decode_doc_data(&context.data.data.after.data)?;

// Modify the document's data
data.hello = format!("{} checked", data.hello);
data.yolo = false;

// Encode the data back into a blob
let encode_data = encode_doc_data(&data)?;

// Prepare parameters to save the updated document
let doc: SetDoc = SetDoc {
data: encode_data,
description: context.data.data.after.description,
updated_at: Some(context.data.data.after.updated_at),
};

// Save the updated document
set_doc_store(
context.caller,
context.data.collection,
context.data.key,
doc,
)?;

Ok(())
}

This hook demonstrates asynchronous processing by reading the initial data saved from the frontend, modifying it, and then saving the updated version back to the Datastore. It's triggered specifically for documents within the "demo" collection and showcases how to handle data blobs, execute modifications, and interact with the Datastore programmatically.


Unlocking Anything on the Internet Computer​

As mentioned in the introduction, the serverless functions extend Juno's capabilities to anything that can be achieved on the Internet Computer. With this in mind, let's explore implementing HTTPS outcalls to a Web2 API in another sample.

Getting the Sample​

To explore this advanced functionality, follow the steps below to clone the repository and set up the project:

git clone https://github.com/junobuild/examples
cd rust/https-outcalls
npm ci

After cloning and navigating to the correct directory, proceed with starting and debugging the sample in your local environment, as outlined in the Getting Started chapter.

Hook Implementation Details​

The hook implemented in this sample interacts with the Dog CEO API to fetch random dog images and update documents within the dogs collection in the Datastore. Here's how it works:


// The data of the document we are looking to update in the Satellite's Datastore.
#[derive(Serialize, Deserialize)]
struct DogData {
src: Option<String>,
}

// We are using the Dog CEO API in this example.
// https://dog.ceo/dog-api/
//
// Its endpoint "random" returns such JSON data:
// {
// "message": "https://images.dog.ceo/breeds/mountain-swiss/n02107574_1118.jpg",
// "status": "success"
// }
//
// That's why we declare a struct that matches the structure of the answer.
#[derive(Serialize, Deserialize)]
struct DogApiResponse {
message: String,
status: String,
}

#[on_set_doc(collections = ["dogs"])]
async fn on_set_doc(context: OnSetDocContext) -> Result<(), String> {
// 1. Prepare the HTTP GET request
let url = "https://dog.ceo/api/breeds/image/random".to_string();

let request_headers = vec![];

let request = CanisterHttpRequestArgument {
url,
method: HttpMethod::GET,
body: None,
max_response_bytes: None,
// In this simple example we skip sanitizing the response with a custom function for simplicity reason.
transform: None,
// We do not require any particular HTTP headers in this example.
headers: request_headers,
};

// 2. Execute the HTTP request. A request consumes Cycles(!). In this example we provide 2_000_000_000 Cycles (= 0.002 TCycles).
// To estimate the costs see documentation:
// - https://internetcomputer.org/docs/current/developer-docs/gas-cost#special-features
// - https://internetcomputer.org/docs/current/developer-docs/integrations/https-outcalls/https-outcalls-how-it-works#pricing
// Total amount of cycles depends on the subnet size. Therefore, on mainnet it might cost ~13x more than what's required when developing locally. Source: https://forum.dfinity.org/t/http-outcalls-cycles/27439/4
// Note: In the future we will have a UI logging panel in console.juno.build to help debug on production. Follow PR https://github.com/junobuild/juno/issues/415.
//
// We rename ic_cdk::api::management_canister::http_request::http_request to http_request_outcall because the Satellite already includes such a function's name.
match http_request_outcall(request, 2_000_000_000).await {
Ok((response,)) => {
// 3. Use serde_json to transform the response to a structured object.
let str_body = String::from_utf8(response.body)
.expect("Transformed response is not UTF-8 encoded.");

let dog_response: DogApiResponse =
serde_json::from_str(&str_body).map_err(|e| e.to_string())?;

// 4. Our goal is to update the document in the Datastore with an update that contains the link to the image fetched from the API we just called.
let dog: DogData = DogData {
src: Some(dog_response.message),
};

// 5. We encode those data back to blob because the Datastore holds data as blob.
let encode_data = encode_doc_data(&dog)?;

// 6. Then we construct the parameters required to call the function that save the data in the Datastore.
let doc: SetDoc = SetDoc {
data: encode_data,
description: context.data.data.after.description,
updated_at: Some(context.data.data.after.updated_at),
};

// 7. We store the data in the Datastore for the same caller as the one who triggered the original on_set_doc, in the same collection with the same key as well.
set_doc_store(
context.caller,
context.data.collection,
context.data.key,
doc,
)?;

Ok(())
}
Err((r, m)) => {
let message =
format!("The http_request resulted into error. RejectionCode: {r:?}, Error: {m}");

Err(message)
}
}
}

This sample not only provides a practical demonstration of making HTTP outcalls but also illustrates the enhanced capabilities that serverless functions offer to developers using Juno.


Conclusion​

In conclusion, Juno's serverless functions mark a significant advancement in blockchain development, offering developers the tools to create more sophisticated and dynamic applications. This feature set not only broadens the scope of what can be achieved within Juno's ecosystem but also underscores the platform's commitment to innovation and developer empowerment. As we move forward, the potential for serverless technology in blockchain applications is boundless, promising exciting new possibilities for the future.

Local development is here!

Β· 4 min read


Hello πŸ‘‹,

I'm excited to share that local dApp development and end-to-end testing are now available on Juno through our new Docker image.

This update serves as a key addition to our upcoming features for the year to come, offering developers a practical solution to build or test their projects in a sandbox environment.

The documentation for this new feature is available here. Moreover, the container's code is open source, and you can access it here for more insights.

In this blog post, rather than reiterating the documentation, I'll provide an example to demonstrate how you can effectively utilize this feature in your development workflow.


Before you begin​

Make sure you have Docker installed on your machine.


Clone the example​

I've prepared a sample project to demonstrate how a dApp can be run and persist data in a local environment. Open your terminal and clone the sample project developed with Astro:

git clone https://github.com/junobuild/examples/
cd examples/astro
npm ci

Run the Docker Image​

To start the container, head to the subfolder containing the configuration I prepared for you.

cd docker

In this folder, you will find two files. A docker-compose.yml file contains essential information for the image, such as the port and a volume. For more details, refer to the documentation.

docker-compose.yml
services:
juno-satellite:
image: junobuild/satellite:latest
ports:
- 5987:5987
volumes:
- astro_dapp:/juno/.juno
- ./juno.dev.json:/juno/juno.dev.json

volumes:
astro_dapp:

There's also a juno.dev.json file, which is designed to set up a collection once the Satellite is populated locally, similar to what you can do in Juno's administration console.

juno.dev.json
{
"satellite": {
"collections": {
"db": [
{
"collection": "counter",
"read": "managed",
"write": "managed",
"memory": "stable"
}
]
}
}
}

Given that everything is set for you, you can run the following command to start the container:

docker compose up

And that's it! The container is designed to manage serving a local Internet Computer replica. It also embeds a custom CLI which handles deploying and populating the Internet Identity and a Satellite. With this setup, you have everything necessary for efficient local development.


Run the dApp​

To get the sample dApp up and running, open another terminal window. Navigate back to the root folder of the project and start the dApp using the following command:

npm run dev

This project leverages our Vite Plugin and libraries, streamlining the setup process with minimal configuration needed. I've already configured it for you, but typically, you would only need to set a container option for the plugin:

astro.config.js
import { defineConfig } from "astro/config";
import juno from "@junobuild/vite-plugin";

export default defineConfig({
vite: {
plugins: [
juno({
container: true
})
]
}
});

And pass along the environment variable to the initialization:

await initSatellite({
satelliteId: import.meta.env.PUBLIC_SATELLITE_ID,
container: import.meta.env.PUBLIC_CONTAINER
});

With the local dApp server active, you can now access it in your browser at http://localhost:4321.

Upon visiting the site, you'll find an option to sign in using Internet Identity. Since everything is deployed locally in a sandbox, your existing identity (anchor) won't be recognized, that's why you will have to create a new one.

A screenshot that showcases the sample dApp home screen

Once signed in, you'll see a "count" action, a simple feature that increments a counter and saves a value associated with your identity.

A screenshot that showcases the sample dApp once signed in

This demonstrates the dApp's capability to interact with local data and user identities.


Conclusion​

In conclusion, the integration of local development capabilities with Juno, using Docker, marks a significant step forward in streamlining and simplifying the development process for dApps.

This setup not only facilitates a more efficient development cycle but also offers a practical environment for thorough testing. It's a straightforward, no-frills approach that underscores Juno's commitment to improving the developer experience without overcomplicating the process.

I am excited to see the innovative applications and solutions the developers of our community will create with these enhanced tools at their disposal.

Setting Up Your Internet Identity on internetcomputer.org

Β· 4 min read


Web 2.0 uses usernames and passwords for logging into websites, which isn't very secure, can be a hassle, and doesn't always keep your information private.

Internet Identity (II), on the other hand, is a better way to log in online. Instead of just usernames and passwords, it uses new technology like fingerprints or Face ID on your phone or special hardware devices to make sure it's really you when you log in.

This authentication provider is used by Juno to secure access to its administration console for developers.

While most decentralized applications on the Internet Computer use the default domain ic0.app for the registration process using Internet Identity (referred to as the "old domain" in this article), Juno defaults to the more recognizable, aesthetically pleasing and easy to remember domain internetcomputer.org.

However, there is a caveat to this choice. When you register with Internet Identity, it's tied to a specific domain. This means that if you have previously created an identity to access other decentralized apps on the Internet Computer, you may not be able to sign in to Juno's console seamlessly using the main "call to action". You won't be blocked from logging in; the login screen also supports the old domain. However, the option to use it is not as prominent.

That's why in this article, we will guide you through the process of ensuring your identity works seamlessly on both domains. By adding a passkey for the other domain, you will ensure that your identity is available for sign-in, regardless of those two choices.

note

In the following instructions, we assume that your identity works on identity.ic0.app, and we are demonstrating how to add it for identity.internetcomputer.org. Of course, this tutorial also applies in reverse; you can simply switch the domain while following these steps.


Step-by-Step Guide​

Here are the steps to follow:

1. Sign-in Internet Identity​

As a first step, you need to login into Internet Identity. Go to https://identity.ic0.app.

2. Add passkey​

As we are looking to register a passkey for the other domain on your device, initiate the process by clicking "Add passkey".

Initiate add passkey screenshot

3. Copy the URL​

Internet Identity will present you with various user-friendly options for registering a new passkey. While these options are handy if you plan to add an additional browser or device, for the purpose of this tutorial, our goals are different.

Therefore, please ignore the information on the screen and only copy the code that is presented to you.

4. Navigate to modified URL​

We are assuming that you want to register the other domain for the same browser. In that case, open a new tab and paste the URL you just copied but, before pasting the link, modify the domain part to point to the other domain.

For example, change a copied link from https://identity.ic0.app/?action=add-passkey&ii=2279219 to https://identity.internetcomputer.org/?action=add-passkey&ii=2279219 by replacing ic0.app with internetcomputer.org.

Note that along the way, you will be prompted to authenticate yourself with your authentication method, such as fingerprint or Face ID. This ensures a secure sign-in on the other domain as well.

5. Enter verification code​

To validate the new passkey, you will be prompted to verify a code in the original tab where you initiated the creation of the new passkey.

Simply select and copy the verification code displayed on the screen.

Return to the previous tab and enter the code. You can either manually type it or, once you've placed your cursor in the first digit field, paste the entire code (Ctrl|Cmd+V), which will be automatically filled.

6. Confirmation​

Congratulations, the passkey on the device you just used for this tutorial is now ready for both the old and other domain.

7. Optionally, rename the new passkey​

The new passkey will inherit a default name. Optionally, you can rename it to make it clear in the future which one is related to which domain. To do this, continue to Internet Identity, select "Rename", and follow the instructions provided.

Conclusion​

In this guide, we've walked you through the process of setting up your Internet Identity for another domain. We hope this has been helpful and will provide you with easy access to Juno's administration console and other dApps using multiple domains for sign-in with Internet Identity.

Introducing Juno Analytics - Unlock Deeper Insights with Privacy in Mind

Β· 3 min read


We're excited to introduce Juno Analytics, a simple, performant, and open-source web3 analytics solution designed with privacy in mind for the developers building decentralized dapps with Juno.

In a digital age where data privacy is paramount, Juno Analytics empowers you to gather valuable insights about your users while ensuring anonymity and respecting their privacy.

Here's a closer look at this powerful new feature:


Privacy-Friendly Analytics​

Juno Analytics is part of our commitment to user privacy. It conducts measurements of your dapps and sites completely anonymously, without using cookies or collecting any personal data.

This means no more intrusive cookie banners, no persistent identifiers, no cross-site tracking, and no cross-device tracking.

Your analytics data remains solely focused on providing you valuable insights without any other ulterior motives.


Performance-Optimized Script​

Our JavaScript library for gathering analytics is designed for peak performance. It consists of a minimal main script that seamlessly integrates with your application's user interface and a dedicated worker responsible for handling logic and cryptography.

This thoughtful design ensures that adding analytics won't slow down your application, even during boot time, preserving your customer acquisition rate.


Comprehensive Tracking​

With Juno Analytics, you're not limited to just basic page views. You can gain deeper insights into your visitors by creating custom events to track conversions, attributions, and more. It's a powerful tool for optimizing your dapps and sites.


Fully Open Source​

Juno is fully committed to the principles of open-source development. Unlike proprietary tools like Google Analytics, Juno Analytics is built with a commitment to transparency and freedom.


You Own Your Data​

All data tracked by our analytics solution is securely stored on the blockchain. As with all our services, you have full control over your smart contracts, and your data remains exclusively yours.


Getting Started​

To begin using Juno Analytics, please refer to our detailed documentation for step-by-step instructions.

It will guide you through the process of setting up and integrating Analytics into your websites and dapps. πŸš€


Conclusion​

We hope you're as excited about Juno Analytics as we are! This feature marks a significant stride toward a more privacy-conscious analytics solution and provide Juno's developers an additional feature in the eco-system to build awesome decentralized applications.
