A Blockchain, originally blockchain, is a growing list of records, called blocks, that are linked using cryptography. Blockchain application development is quickly gaining traction across multiple industries.

Blockchain Application Development :

Architectural approaches that make blockchain application development. We will address five simple software development approaches for blockchain applications.

Bootstrapping The Development Environment Setup:

We need to have our own chain running and we should have the knowledge to launch a local node before getting into blockchain application development. We connect some kind of public test in blockchain-network that tests should be run and maintained by someone else and out of our control. The ARK Deployer delivers the promise of seamless and easily customizable blockchain deployment in three simple steps. All ARK based bridge chains are accompanied by free and open-source SDKs. SDKs enable you to jump right into application development and leave the blockchain protocol and sysadmin details to be taken care of by our automation tools.

Everything we learned is combined with our expert knowledge and it guides us towards building a product to enable easy and simple deployment of your very own custom blockchain.

ARK Logic: Blockchain Application Development Steps:

With ARK’s modular core our distributed-servers/nodes running in the background translate into containers where you can deploy your own blockchain-based applications. You don’t need to worry about consensus protocol or peer-to-peer network mechanics, It’s a protocol thing, just like TCP/IP, well a lot more complex but it is running in the background, delivering security, trust and immutability delivering the promise of blockchain.

Distributed Blockchain Applications in General:

One of ARKs’ promises is to deliver tools and practices that will close this gap and make blockchain application development. This gives us the power to create agnostic blockchain applications that can run within any blockchain-based on ARK Core technology.

By bringing the ARK Ecosystem in new interchain monetization services allowing businesses to fully exploit and research new crypto driven business models. Our blockchain application development approach is to close the gap between traditional development practices by bridging the concept of software libraries and blockchain development.

ARK Logic: Basic Overview of dapp Structure:

Blockchain application is an abbreviated form for decentralized application-dapp which can already be deployed as a blockchain module. A dapp has its own backend code which is running on a decentralized peer-to-peer network (ARK), Contrast this with an app where the backend code is running on centralized servers.

A dapp have frontend code and user interfaces written in any language that can make calls to its backend via simple API calls, or by using any kind of protocol that was implemented as a communication channel in the dApp module implementation. A dapp can host its frontend on a decentralized network, in this scenario, the language limitations must be compatible with our core-technology language landscape and our blockchain network servers as an application provider. A dapp is able to implement only microservices, allowing modular design, easier bug-fixing, and upgrading as a normal software application.

Now we can deploy a module, like in most web applications ARK Logic  enables your application to run in a modular fashion on the distributed network. Your application life cycle is inherited by the overall life cycle of a blockchain node. A strong benefit of plug-able modules is having access to the blockchain mechanics in a very simple way. Blockchain interaction is something that should be taken very seriously and it can be deliver via the following approaches.

ARK Logic: Best Practices:

We will look into five core approaches that enable you to seamlessly develop distributed blockchain applications on top of our platform. You will learn the way to interact with the blockchain state, the way to interact with the blockchain database, learn to use events and react to state changes, you can add new API endpoints via customizable HTTP server running within core nodes and Pack your blockchain application as a module and distribute it.

1Interaction with the blockchain state:

The core-blockchain package is the central entity and everything revolves it. It also provides a state-machine that helps you in controlling the state of your node and switches between states to sync, rollback or recover from a fork. It holds all of the information that is important when you want to see what the current state of your blockchain node is. You should not trust the database, trust the in-memory data it exposes, as it’s updated in real-time.

  1. Interaction with the database:

It is easy to access blocks and transactions in a very simple and efficient way by using the database plugin.

  1. Use events to listen and react to changes:

Core provides a package which is called core-event-emitter which exposes an instance of the Node.js EventEmitter. A common use-case of this is that your module will listen to those events that core emitted in order to process the data for monitoring. Your module also has the ability to emit events that can be listened to by other plugins (or your own for internal use).

  1. You can add new API endpoints:

You can add new API endpoints via customizable HTTP server running within core nodes. A common use-case for a plugin is that you can process some data from within core and if you want to make use of that data with an external application. The easiest way to do this is that you can do this through an HTTP server that exposes an API from which you request the data.

  1. Pack and distribute your blockchain application:

You can pack and distribute your blockchain application as a module. The last piece of the puzzle is that it start packing everything into a module and distributing it to your blockchain network. Our plugins are modular by design, it means that the concepts which are described above will all be already developed inside your own module. It is great to having your own module because it enables you to publish it to the largest package repository thus making it available to everyone.

Modules are very simple to write at there core they are an object with a registered property. That is a function with the signature a sync function. Additionally, the plugin object also required pkg property and several optional properties including version.

Using the above-mentioned concepts helps you to make your blockchain application development a breeze and it lowers the gap between enterprise application developers and crypto developers. Ambiguous solutions encourage you to test these approaches and start building your first blockchain application.

Conclusion- What is Blockchain Application Development:

This Blockchain Application Development series will cover an introduction to developing custom transaction types with our Generic Transaction Interface (GTI). The basic premise of the Generic Transaction Interface is to provide an easy way to implement and include new transaction types in your blockchain without having the need to modify more complex parts of the Core. It can be very simple such as including pre-defined templates depending on the use case of the blockchain or we can re-use already present types and modify their parameters to introduce new ones. The development of custom transaction types enables you to add your own custom logic and data and then validate it via existing consensus mechanisms and store it on-chain.After doing that you will master all the skills which are required to build blockchain applications with ARK Logic.
