Talk  to Blockchain Developer

Blockchain Development Team

Everyone in the technology sector is always 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 is a method of storing data so that it is difficult or impossible to alter, hack, or scam it. A blockchain acts as a database, storing information in a digital format. Blockchains are well recognized for their critical function in keeping a secure and decentralized record of transactions in cryptocurrency systems like Bitcoin. The blockchain's uniqueness is that it ensures the accuracy and security of a data record while also generating trust without the requirement for a trusted third party.

However, the way data is formatted differs significantly between a typical database and a blockchain. A blockchain organizes data into groupings called blocks, each of which contains a collection of data. Blocks have specific storage capabilities, and when they're full, they're closed and connected to the preceding block, producing a data chain known as the blockchain. All additional information added after that newly added block is compiled into a new block, which is then added to the chain after it is filled.

A database organizes data into tables, but a blockchain organizes data into chunks (blocks) that are linked together, as the name suggests. When implemented in a decentralized manner, this data structure creates an irreversible data timeline. When a block is filled, it becomes permanent and part of the timeline. When each block is added to the chain, it is given a specific timestamp.

Blockchain is a distributed, unchangeable ledger that makes recording transactions and managing assets in a corporate network easier. 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.

Blockchain is a sort of distributed ledger technology in which transactions are recorded using a hash, which is an immutable cryptographic signature.

This implies that if a single block in a chain is modified, it will be immediately clear that the chain has been tampered with. Hackers would have to modify every block in the chain, across all distributed copies of the chain, if they intended to destroy a blockchain system.

Blockchains like Bitcoin and Ethereum are constantly expanding as new blocks are added to the chain, increasing the security of the ledger immensely. Despite the fact that blockchain isn't a buzzword for attracting investors, but a well-established technology, there's still plenty of room for business ideas.

The Importance of Blockchain

Businesses are based on information. The sooner and more precise it is received, the better. Blockchain is excellent for delivering such information because it delivers instantaneous, shareable, and entirely transparent data kept on an immutable ledger that can only be viewed by network members with permission.

Sales, transactions, finances, production, and much more may all be tracked via a blockchain network. For businesses that deal with finances, this adds an unprecedented layer of accountability that allows each sector of the company to act with integrity towards its business growth. You can see all facts of a transaction end to end since members share a single view of the truth, providing you more confidence as well as additional efficiencies and possibilities. Blockchain is unique in that no one is in control; instead, the individuals who utilize it run it. Bitcoins can't be counterfeit, hacked, or double-spent, so those who hold them may be certain that they're worth something.

A blockchain's key components

Distributed Ledger Technology

The distributed ledger and its immutable record of transactions are accessible to all network members. Transactions are only recorded once using this shared ledger, reducing the unnecessary duplication that is common in traditional corporate networks.

Immutable Records

After a transaction has been logged to the shared ledger, no participant may edit or tamper with it. If a mistake is found in a transaction record, a new transaction must be made to correct the problem, and both transactions must then be accessible.

Smart Contracts

A collection of rules called a smart contract is recorded on the blockchain and performed automatically to speed up transactions. A smart contract can specify requirements for corporate bond transfers, as well as payment terms for trip insurance.

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 influence the conventional banking system

How Does a Blockchain Work?

The purpose of blockchain is to enable the recording and distribution of 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

A public blockchain, such as Bitcoin, is one that anybody may join and participate in. 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 a 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. Because most firms want blockchain developers to design blockchain apps that users with little or limited knowledge of blockchain can use, web development is essential. 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. The members of a group have complete control in this situation. The group in these circumstances is made up of many organizations. The Energy Web Foundation is a great example of this sort of blockchain architecture.

Private architecture

Only a few people are involved in private blockchain architecture. It's a widely used application in businesses. Sawtooth and Fabric are two well-known examples of this type of architecture. 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. The blockchain development team will create a PoC for your business use case and test 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

Because 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.
