Talk  to Blockchain Developer

Blockchain Development Team

Everyone in tech keeps hearing about blockchain development. If you work in technical or financial circles, you're well aware of cryptocurrencies and why they're so popular among crypto enthusiasts.

Choosing the perfect blockchain development team for the business is crucial in effectively building a blockchain application. It will need to be carefully monitored, interface with your existing technological platforms, and solve a variety of information security concerns, in addition to establishing the underlying blockchain platform and working on the actual blockchain app development.

Blockchain and its Variations

Blockchain uses a unique data storage method that is difficult or impossible to alter, hack, or scam it. Functioning as a database, digital information can be stored on the blockchain. Blockchains are the established infrastructures keeping a secure and decentralized record of transactions in cryptocurrency systems like Bitcoin. The blockchain's uniqueness is that it ensures the data stored remains accurate while also serving as a source of truth without a third party to the transactions in question.

However, the way data is formatted differs significantly between a typical database and a blockchain. Most blockchains order data in groups called blocks that contain a collection of important information. Transactions are verified by nodes who publish the new state to the network, announcing the creation of a new block which is then appended by other nodes in their ledger copy. Initially, transactions go to a mempool where they are picked by nodes who solve complex maths puzzles to add a new block of transactions to the network by essentially linking such transactions to every transaction since day 1.

While most databases organize data into tables, a blockchain organizes data into chunks that are linked together, as the name suggests. When implemented in a decentralized setup, the data structure forms a tamper-proof data timeline. Filled blocks are a permanent part of this timeline. All blocks are added to the chain with a specific timestamp.

Blockchains are distributed ledgers that facilitate the recording of transactions in real-time, and coordination of assets exchanged between parties on a network. A tangible asset (a home, vehicle, cash, or land) can be intangible (intellectual property, patents, copyrights, branding). On a blockchain development, virtually anything of value may be recorded and sold, lowering risk and cutting costs for all parties involved. The technology belongs to the class of distributed ledger technology which allows transactions to be verified stored and updated using a process of hashing and random guessing for a nonce.

With blockchain technology, no piece of the data can be modified separately, as every update follows through a verification down to the last chain. Malicious users must modify every block in the chain, across all distributed copies of the chain, if they ever hope to gain an unfair advantage on the network.

Blockchains like Bitcoin and Ethereum are constantly expanding as new blocks are added to the chain, increasing the security of the ledger immensely. In the face of this growth due to massive adoption and the significant interest from investors, there are still lots of opportunities and possible business ideas that can be implemented with blockchain technology.

The Importance of Blockchain

Businesses are based on information, and getting this information across without delay is crucial to business success. Blockchain is excellent for delivering such information because it delivers instantaneous, shareable, and entirely transparent data that is stored on a distributed and trustless ledger verifiable by parties on all ends of the communication channel.

Sales, transactions, finances, production, and much more may all be tracked via a blockchain network. The accounting benefits of the blockchain are particularly expedient for those businesses that deal with finances since they can have an extra layer of accountability that allows each sector of the company to act predictably towards growth. All transactions are also visible from all ends offering a single source of truth with confidence as well as additional efficiencies and possibilities. Aside from the fact that blockchain-based systems like Bitcoin can't be counterfeit, hacked, or double-spent, they are also decentralized which means that no central authority is in control of the network activities.

A blockchain's key components

Distributed Ledger Technology

The distributed ledger is a record of transactions that cannot be changed by anyone yet it is available and accessible by all members of the network. Transactions are recorded just one unique time using this shared ledger, reducing the unnecessary duplication that is characteristic of traditional corporate networks.

Immutable Records

Transactions logged to the shared ledger remain so and outside the editing reach of all participants. It is almost impossible for the erroneous transaction to be on the network because validators check the very first transactions before verifying that such a transaction is valid.

Smart Contracts

Smart contracts are like if-else statements and they are an on-chain representation of real-world instructions and agreements. The use case of a smart contract extends to virtually anything you can do today with the help of a lawyer but the terms must be spelled perfectly because the contract is self-executing.

Decentralized finances are changing lending and investing processes with smart contracts. Guaranteed payments and high-interest rates encourage people to convert fiat money to crypto and invest in liquidity pools. However, distributed app development also influences the conventional banking system

How Does a Blockchain Work?

Blockchain makes it possible to record and distribute digital products without the ability to modify them. In this sense, a blockchain serves as the foundation for immutable ledgers, or transaction records that can't be changed, erased, or destroyed.

In basic words, blockchain operates through a multi-step development process that goes like this:

  • A transaction is entered by an authorized participant and must be authenticated by the technology.
  • This operation generates a block that reflects the transaction or data in question.
  • Every computer node in the network receives the block.
  • The transaction is verified by authorized nodes, who then add the block to the current blockchain. Miners are nodes in public blockchain networks who get rewarded for their labor, which is commonly done through a procedure known as Proof of Work and is usually done in the form of bitcoin.
  • The transaction is completed when the update is delivered across the network.

These business processes occur in near-real-time and include a variety of factors.

Types of blockchain networks

A blockchain network may be built in a variety of ways. They can be public, private, permissioned, or constructed by a group of people.

Public blockchain

There are no restrictions on public blockchains which mean everyone can join in and participate in on-chain activities. Significant computer power is required, there is little or no privacy for transactions, and security is inadequate. These are crucial considerations for blockchain use cases in the industry.

Private blockchain

Private blockchain networks are decentralized networks, similar to public blockchains. The network itself is an upgraded version of Ethereum that allows for private transactions. However, the network is governed by a single organization, which determines who is authorized to participate, implements a consensus procedure, and maintains the shared ledger. Depending on the use case, this can greatly increase participant trust and confidence. A private blockchain can be used for firewalls and even hosted on-site within a blockchain development company.

Permissioned blockchain

A permissioned blockchain development is typically put up by businesses that create a private blockchain. It's worth noting that public networks can be permissioned as well. This limits who is authorized to engage in the network and what transactions they may do. To participate, participants must first get an invitation or authorization.

Web Development in Blockchain

A blockchain developer's primary focus is web development. When blockchain developer first starts in the industry, the majority of them are responsible for the basic design of decentralized app development. This implies they should be familiar with the fundamentals of both front-end and back-end programming, such as designing interactive graphical user interfaces for Dapps, API management, and request processing, among other things.

In most situations, a blockchain developer will be working on web application development. They will become familiar with all areas of web development after learning it, and they will be able to utilize this knowledge to construct strong online app development that employs blockchain technology.

They'll need to study web development, app development, and programming, which will all help them create better Decentralized applications. Most firms also want blockchain developers to design blockchain applications that users previously using their Web 2.0 applications can use. They will be greatly assisted in this effort by their extensive design experience. Core areas of expertise of a development company are mobile app development, web-oriented software products, and business software solutions.

Blockchain Developers Skills and Checklist

The duties of blockchain developers are numerous. They'll need a few skills to be able to manage such responsibilities effectively. In order to be a good blockchain developer, certain skills must be developed and mastered.

Cryptography

Cryptography is the study of techniques that prevent unauthorized individuals from gaining access to your information. To perform cryptocurrency transactions, you'll need a wallet and the key to that wallet. That key is necessary because it establishes your ownership of the wallet. Cryptocurrency provides secure transactions via the encryption and decryption of public and private keys.

Cryptographic hashing is another important concept in cryptography. Hashing is the process of obtaining a particular length output from an input of any length. The hash function might store information with 20 or 200 characters, but it will only return data of the length you choose.

Cryptography is certainly necessary for blockchain technology to function properly.

Data Structures

As they construct and execute networks, blockchain developers interact with a variety of data structures on a daily basis.

Even a block is a form of data structure, therefore the entire blockchain network is built up of them. Because it is a container data structure, a block clusters transactions for the public ledger, whereas the public ledger is the blockchain.

Second, aspiring to be a blockchain developer necessitates a deep understanding and practical understanding of data structures. To satisfy their own network needs, the best blockchain developers are continually experimenting with and changing existing data structures.

Blockchain creates a safe and immutable system by combining a variety of data types with powerful cryptography. Knowledge of blockchain can only be considered incomplete if it is not accompanied by an understanding of data structures.

Blockchain Architecture

There are three types of blockchain architecture:

Consortium architecture

The consortium's architecture isn't entirely decentralized. Members of a group can control the network to some extent. These groups are mostly formed by non-governmental or governmental organizations. A good example of one of such a group is the Energy Web Foundation.

Private architecture

Only a few people are involved in private blockchain architecture. It's a widely used application in businesses. Two popular examples of this type of architecture are Sawtooth and Fabric. Another important characteristic of such architecture is that it is not decentralized.

Public architecture

The most decentralized sort of blockchain architecture is public architecture. You may participate in the network by mining or conducting trades. Bitcoin is the most well-known example of public blockchain architecture, and you've probably heard of it.

Basic Programming Ability

Because blockchain platforms like Ethereum and Bitcoin are always changing, it's important for blockchain developers to keep up with the newest blockchain development. They should be familiar with well-known blockchain solutions and know-how to build on them.

Encryption and Security Knowledge

Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are two encryption and security technologies that blockchain developers should be aware of. They must also understand how to use security features such as data encryption and multi-factor authentication.

A distributed database that operates on the internet is known as a blockchain. As a result, blockchain developers must be familiar with networking principles like peer-to-peer networks, packet transport over the internet, routing, and so on.

A good understanding of encryption and security protocols, as well as networking fundamentals, is required of a blockchain developer.

Building a Blockchain Software Development Team

Choosing the right blockchain development team for a development company is a crucial factor in effectively building a blockchain app development. It will need to be properly managed, interface with your existing technological platforms, and solve a variety of information security concerns, in addition to establishing the underlying platform and developing the actual blockchain applications.

The blockchain developers will analyze your business infrastructure to identify business challenges and opportunities that blockchain technology can address. Our blockchain development team will help you think through your business process in a technical way and develop a solution to boost your operational efficiency and productivity.

Platform Deployment

The first thing to think about is where you'll host your platform. The challenge of developing a blockchain solution is far from easy and uncomplicated.

Hosting the infrastructure yourself

Since blockchains require a lot of setups, hosting the infrastructure yourself necessitates a considerable amount of committed DevOps resources. On the other side, this gives you additional options, allowing you to entirely customize the blockchain to your own needs if you have the time and means to do so.

Cloud-based Blockchain-as-a-Service solutions

Cloud-based Blockchain-as-a-Service solutions are those in which a third party constructs and operates a blockchain solution on your behalf. However, for the greatest outcomes, you'll need some in-house experience.

Fully-managed services

Fully-managed services are the simplest to use. They not only set up the infrastructure for you, but they also handle every part of it. This helps to reduce the inherent complexity of blockchain, albeit it still has certain issues when compared to other systems.

Development

You'll need more than just the underlying blockchain platform; you'll also require blockchain-based programming. Smart contracts or Decentralized Apps are the terms used to describe this programming. Ethereum, IBM's Hyperledger Fabric, and R3's Corda are the three most popular systems in this space. For writing and implementing smart contracts, Ethereum employs its own programming language, Solidity, whereas Hyperledger Fabric supports JavaScript, Golang, and Java. Corda, on the other hand, currently only supports Java.

From a blockchain development standpoint, smart contract generation may be rather time-consuming. It takes time and knowledge to do it properly, but because of the popularity of the three blockchain platforms described earlier, there are many publicly accessible sample web apps for each, all of which are backed by a number of experienced programmers within these communities. This is especially true in the Ethereum community, which has attracted a large number of enthusiasts who are well-versed in the technology and how it works.

Moreover, no blockchain platform is self-contained; you'll need to integrate it with your existing technological stack. Hyperledger Fabric, as previously indicated, includes native libraries for Java, Golang, and JavaScript, but Corda is limited to Java. Ethereum, on the other hand, supports a far diverse range of latest technologies, due to its thriving community.

Security

Last but not least, a blockchain platform's security is mostly determined by key management and network security. Using blockchain at all necessitates the creation of cryptographic keys for your blockchain apps, which must be kept in a safe location.

Hardware security models

Hardware security models are tamper-proof physical devices that are used to store your keys. In the event that a breach is attempted, the specifics of the attempt are saved, and your blockchain development company can be notified.

Cloud-based security models 

Cloud-based security models, such as Azure's Key Vault and Amazon Web Services Key Management Service, provide the same service on the cloud.

Secret management tools

The HashiCorp Vault is an example of a secret project management tool, a type of database for storing secrets.

You'll also need to make sure you can physically link to the other companies on your blockchain network. It is a good business idea to check with your Information Security teams to ensure there aren't any obstacles.

Conclusion

To ensure the success of your blockchain deployments, you must have the correct blockchain development team in place. To do it right, you'll need to make several compromises and considerations along the road, just as with any new technology or open platform development.
