What Does a Blockchain Development Company Do?

About 420 million people worldwide currently use cryptocurrency. Despite being a relatively recent development, blockchain technology has gained a huge amount of interest in recent years. Cryptocurrencies like Bitcoin and Ethereum are now used worldwide, but many people still know very little about the entire crypto space. Several companies work in the field of blockchain development, which is leading to significant advancements in the space. You may be wondering, however, what does a blockchain development company actually do? In this guide, we’ll cover everything you need to know. Keep reading for more.

What Is a Blockchain?

Before the release of Bitcoin in 2009, almost no one had heard the term “blockchain” – now it’s well renowned as one of the biggest technological advancements in recent years. It empowers Bitcoin and other cryptocurrencies, allowing people to trade them in a secure, reliable way. A blockchain is a distributed ledger or database that’s shared among the various nodes of a computer network. It stores a wide array of information relating to all transfers and transactions made on the network. There are various uses for blockchain, but crypto is the most well-known one. The records of every transaction are recorded, and these can’t be altered or manipulated in any way by anyone. For example, if an individual was to send 5 Bitcoins from their wallet to someone else’s, the details of that transaction would be permanently recorded. All information is publicly available, so anyone could go on and see the details of this, or any other transaction. Traditional databases are structured using tables, but blockchains differ in this. Blockchains store data in blocks which are then strung together. This creates an irreversible timeline, which is why no records can be manipulated.

Information Contained in Each Block

Each block in a blockchain contains information made up of three parts:

  • Transaction details such as date, time, and value
  • Details of participants based on digital signatures

The CHF uses a mathematical algorithm to ensure every block is unique and set apart from any others. Within Bitcoin’s blockchain, each block can hold about 1 MB of data – this may not sound like a lot, but it’s enough to store the details of thousands of transactions.

What Is a Blockchain Developer?

Blockchain developers (sometimes known as blockchain engineers) are individuals who do any kind of development work related to blockchains. This could involve developing blockchains themselves, or a range of other solutions that blockchain technology has made possible.

Core Blockchain Developers

Core blockchain developers build the central architecture of blockchain networks. There’s a lot of responsibility here, as it involves making decisions about things like the overall blockchain design and the consensus protocol. Security conventions also fall under this umbrella, and security is one of the key elements of blockchain technology.

Blockchain Software Developers

Blockchain software developers create applications that use blockchain technology. These apps are known as dApps (decentralized applications) which distinguishes them from traditional apps. This isn’t too different from standard app development, but there are some additional elements. A dApp developer needs to have a solid understanding of how to develop smart contracts – Solidity is a programming language that is specifically designed for writing smart contracts on blockchain platforms. It is an object-oriented language that is similar to JavaScript and is used to write the code that runs on the Ethereum blockchain. Solidity is a crucial programming language in blockchain development, as it enables developers to design and implement decentralized applications (dApps) that can autonomously execute intricate transactions without relying on a centralized authority. Leveraging Ethereum’s smart contract functionality, Solidity facilitates the creation of self-executing agreements that are transparent, secure, and tamper-resistant, thus fostering trustless interactions between parties in a decentralized ecosystem.

Why Use Blockchain?

Over the years, we have moved online more and more. Now, almost all businesses and organizations rely on the internet to some degree. While this offers many advantages, it also presents certain risks. Cybercrime is always on the rise, so people and organizations must do what they can to protect themselves. Projections show that cybercrime will cost the world $10.5 trillion annually by 2025. One of the key advantages of blockchain technology is its security. As the data recorded in blocks can’t be altered, it helps ensure records stay secure at all times. The technology is also very cost-effective, which can help businesses save a lot of money. When first introduced, financial transactions were the only viable use of blockchain technology. That has since changed, and more solutions are becoming available every year. Some that are already in use include copyright protection, medical archiving, reward programs, digital voting, and more.

Different Blockchain Solutions

Companies are starting to use blockchains for various reasons. Solidity.io can help you produce different solutions to meet your business needs.

Smart Contracts

Smart contracts are an integral part of any Web3 project on the Ethereum blockchain. They allow organizations to create decentralized solutions for different products, services, and use cases. This includes things such as:

  • NFT-based ticketing systems
  • Smart Contract-based escrow services
  • Asset-indexing
  • Lending
  • Other on-chain financial products

Smart contracts are being widely adopted for more and more different uses within a huge range of businesses and entities. In the coming years, the possibilities will only continue to grow.

NFT Launches

NFTs (non-fungible tokens) are another aspect of blockchain technology that has become incredibly popular in recent years. They’re digital assets that can be bought, sold, and traded within blockchains, and while they started on the Ethereum blockchain, several others have now introduced them.

They’ve gained significant popularity due to several collections that have had single NFTs sell for hundreds of thousands of dollars. The most expensive NFT bought by a single individual to date is Everydays: the First 5000 Days – a piece by artist Beeple – which sold for $69.3 million.

While many are simply digital works of art, they can come in a range of formats. Ultimately, an NFT is proof of ownership of a digital asset, which makes them ideal for many use cases including:

  • Intellectual property
  • Event ticketing
  • Investment ownership stakes
  • Club memberships
  • Physical property ownership

This has become very popular in the world of art as it allows artists to take more control over their work, and they can continue to generate income even after the initial sale. When placing an NFT on a marketplace, royalties can be included. The creator will then receive these royalties every time the NFT is sold again. For example, if an NFT has a 5% royalty fee and someone sells it to another collector for $1,000, the original artist will receive $50. If you’re planning to build an NFT project, executing a well-organized launch event is crucial for attracting early adopters and investors. Solidity.io, as one of the leading blockchain development firms, can assist you in creating a successful launch event tailored to your project’s unique requirements.

When this kind of thing is possible, it’s always a good idea to perform audits. Depending on what your business does and the solutions your providing, this security could be vital to your business as well as your customers. On top of the potential financial loss, any lapses in security could also result in a loss of trust among your consumers. This is a surefire way to permanently damage the reputation of your business and potentially lose a lot of customers. Solidity.io’s comprehensive security audits are an essential part of ensuring the highest quality for your blockchain-based products. By leveraging their expertise in smart contract auditing and industry best practices, you can operate with confidence and build trust among your customers, team, and stakeholders.

Advantages of Using Blockchain

As more people gain an interest in blockchain technology, they’re starting to see all the use cases for it. Beyond just allowing people to transfer funds, blockchain technology offers several other advantages.


One of the standout characteristics of blockchain technology is that it allows for full decentralization. This means there’s no ‘middle man’ in the form of a government, bank, or other financial institution controlling things. There are also no third parties involved. Transactions are instead facilitated by computers all over the world. Note that while these computers help process transactions, only your blockchain can access a transaction that you make.


Blockchains employ an append-only data structure, which ensures that once records are added, they become immutable and resistant to tampering. This characteristic provides an additional layer of security that distinguishes blockchain from many other technologies. By preserving the integrity of the stored data and maintaining a transparent, chronological history of transactions, blockchain technology fosters trust and confidence in the system, making it an ideal foundation for secure and decentralized applications.


As previously emphasized, security is of paramount importance in the digital realm, and many Web3 solutions offer enhanced security compared to their predecessors. Each block undergoes a rigorous verification process before it can be appended to the chain. This process relies on a consensus mechanism among participants in the distributed ledger, thwarting malicious activities and safeguarding against unauthorized alterations. The decentralized nature of blockchain technology, combined with its consensus-driven approach, bolsters security and fosters trust in the Web3 ecosystem.


These days, transparency is considered almost as important as security. People don’t want to blindly trust organizations, so being able to see what’s going on makes people feel far more comfortable. Every user on a network can access the full documentation of that blockchain. People can view details of any transaction, including wallet addresses, transaction amounts, dates and times, and more. This way, people can be confident that there’s no suspicious behavior going on, resulting in an increased level of confidence and trust.


Cost efficiency is an advantage to all business operation, making blockchain technology beneficial for any company. Things like transaction fees are typically very low, even when sending large funds. This becomes even more significant when international transfers are involved as they can often come with some sizable charges. Blockchain technology is also more efficient in terms of speed. Transfers are much faster, which is beneficial for both parties in a transaction – with international transfers, it can reduce the time from several days to just seconds. For businesses, assets can also be recorded, stored, and traced with ease.

Companies That Use Blockchain

Over the years, more and more companies have begun adopting blockchain systems. Some of the largest include:

Many organizations (banks in particular) have expressed a reluctance to use cryptocurrencies over the years. With time, however, it has become more clear how advantageous it can be. As a result, more businesses take an interest every year, both in the US and across the globe.

Current Use Cases

As it stands, the most well-known use of blockchain technology is for financial transactions. Aside from that, several other sectors have started making use of the benefits it offers:

Real Estate: Accurate, secure records of property and land ownership Healthcare: secure patient records with heightened security resulting in more trust in the clinical research process Voting: Secure voting systems that are resistant to ballot duplication Supply chain: Precise asset tracking throughout the entire process from the vendor to the customer

It’s still early for blockchain technology, so in the coming years, the number of use cases will only increase.
