An overview of the blockchain development lifecycle

This course of is a confirmed and examined methodology for blockchain builders within the trade.  Organizing the method on this method yields essentially the most environment friendly and splendid outcomes. The blockchain utility improvement course of includes eight steps, detailed under. 

The eight steps within the blockchain improvement lifecycle:

Outline the issue to be resolved with blockchain utility 

Step one of this course of entails figuring out an issue {that a} blockchain can resolve efficiently. It may be each pricey and pointless to make use of a blockchain when it’s not required. Due to this fact, it’s important to establish a real-world downside {that a} blockchain can resolve.

Select the best-fitting consensus mechanism

Every blockchain undertaking makes use of its personal consensus mechanism. The commonest are proof-of-work (PoW) and proof-of-stake (PoS). Different consensus mechanisms like sensible Byzantine fault tolerance, proof-of-burn, proof-of-activity and proof-of-capacity might be adopted provided that they’re higher suited to the undertaking.

Resolve on a programming language and blockchain

At this level, concentrate on designing the consumer interface of the applying. The chosen blockchain to be constructed on will have an effect on the programming language used, which in flip will affect how customers work together with the chain. Furthermore, interoperability is a further consideration when considering of languages. However, which programming language is used for blockchain applied sciences? 

A number of the fashionable programming languages for blockchain builders are as follows:


After choosing a language, a blockchain developer ought to choose a database to work with. MongoDB and MySQL are two fashionable selections.

Choose a blockchain improvement platform

At this stage, builders ought to establish which blockchain to construct on. This permits for instant improvement with out having to create a blockchain from scratch. The blockchain platform choice course of will depend on the consensus mechanism that’s required. Be aware of the issues resolved by every consensus mechanism.

Blockchain improvement usually depends on fashionable platforms designed to make the method simpler. These platforms are utilized by each blockchain improvement corporations and unbiased builders.

A number of the commonest platforms are open-source blockchain platforms, resembling


Builders ought to select a platform that makes use of a well-recognized blockchain programming language. Each platform listed right here will facilitate the blockchain improvement cycle.

It’s finest to look into every platform’s capabilities and downsides, which can assist decide whether or not the blockchain platform fits the undertaking.

Develop a technique for the rest of the event course of

On this step of the blockchain improvement course of, consider the steps taken up to now. Lay out a plan, and prioritize a technique for a extra complete course of. This technique ought to account for the traits of the chosen platform. 

Start to design the blockchain structure

Decide if the blockchain will embody particular permissions for focused consumer teams or if it’ll comprise a permissionless community. Afterward, decide whether or not the applying would require using a non-public or public blockchain community structure. 

Additionally think about the hybrid consortium, or public permissioned blockchain structure. With a public permissioned blockchain, a participant can solely add info with the permission of different registered contributors.

Finally, the choice value contemplating is the one that most closely fits the use case.

Develop the blockchain utility

Configure the important thing facets of the applying. Be certain that permissions, block signatures, tackle codecs and key administration are addressed first. These components can’t be modified as soon as carried out, so it’s finest to present them some consideration from the beginning.

After this stage, begin engaged on the blockchain utility’s Software Programming Interface (API). APIs are used to carry out auditing capabilities, generate key pairs, and retailer or retrieve important knowledge. The choice of blockchain APIs relies on the aim of the applying. These APIs will present essentially the most worth to all customers. 

A developer should additionally arrange middleware. Middleware is software program that connects exterior methods to the blockchain, thereby permitting communication between blockchain elements and the apps operating on it.

Some APIs required by nearly each blockchain embody

APIs for digital signatures and producing hash numbers are additionally required for knowledge authentication. The developer might use prebuilt APIs for blockchain functions or select to create new ones from scratch. Counting on prebuilt APIs quickens the event course of whereas constructing APIs from scratch gives better flexibility.

Check and launch an alpha model of the applying

On this step, all the accrued efforts from the earlier steps pays off and an early model of the undertaking is now prepared for testing. At this stage of the event course of, concentrate on the core capabilities. Builders ought to attempt to spot potential points as they come up.

It’s finest to start out with the naked minimal. A Minimal Viable Product (MVP) is all that’s required to show the blockchain mannequin’s viability. As soon as the applying is steady, the developer might select to include extra complicated options.
