An Overview of Blockchain Technology
Blockchain Technology has tremendous potential, especially in the Finance sector. You must have heard the term “Blockchain Technology” in the last few years. It is becoming more and more popular with the use of cryptocurrencies like Bitcoin.
Basically, blockchain technology is a method of recording information, which makes it almost impossible to be manipulated. It is a type of Digital Ledger and record keeping is a crucial aspect for any business.
The most popular use of blockchain technology is Bitcoin, which is a cryptocurrency. It uses a cryptography proof instead of third-party trust for two entities to enable transactions over the internet.
In blockchain technology, there is no central server or system which keeps the data. Instead, the data is distributed over millions of computers across the world. As a result, data is notarized and present on every node, which is publicly verifiable.
Future of Blockchain Technology & Blockchain Developers
Blockchain technology will have a significant impact on the future of secure data management, logistics, gaming, and more sectors. It can also be used to automate various processes and remove intermediaries.
Although blockchain technology is predominantly used in the finance industry at present, it will have diverse applications in the near future. It can play a key role in the healthcare sector by increasing the interoperability and security of healthcare data.
Blockchain technology can also be used in the travel & hospitality industry for storing important documents like passports, Identity cards, managing travel insurance, reservations, loyalty and rewards.
As the use of blockchain technology for various processes increases, the demand for skilled blockchain developers will continue to grow. These professionals will be at the forefront of creating decentralized, transparent solutions for diverse industries. A blockchain developer with sound knowledge of the technology and its applications will be increasingly in demand.
Skills to Look For in A Blockchain Developer
Cryptography: A skilled blockchain developer should be good at cryptography, as this profile demands a good understanding of cryptography. It is the foundation on which Blockchain is built and a developer should be able to design secure as well as efficient algorithms.
Solidity: This is the programming language which is used to create smart contracts on the Ethereum blockchain. Solidity is a high-level language, which is similar to JavaScript. A blockchain developer should be good at Solidity for building Decentralized Applications (DApps) on Ethereum.
Linux: Most of the software related to Blockchain runs on Linux operating systems, as a result, a blockchain developer should be well versed with Linux. Although there are different variants of Linux OS, blockchain developers should focus on learning how they all work and not restrict themselves to learning just one.
Databases: A blockchain developer should have knowledge of popular databases like MySQL, MongoDB and Cassandra. This knowledge is useful when working with large amounts of data on Blockchain.
Networking: A good grasp of networking technologies is required to build applications that can interact with other computers on the blockchain network. Along with this, familiarity of protocols like HTTP and TCP/IP is necessary.
Soft Skills: As a blockchain technology solution requires collaboration with other developers, a skilled blockchain developer should be good at team work, communication and time management.

- Team Lead/Architect: $150,000+ annually (even higher hourly rates)
Blockchain Development Cost Based on Project Complexity:
The complexity of the blockchain application has a very big impact on the cost of development. The reason is that a complex application requires more time and manpower to be developed.
There are several factors which add to the complexity including data structures, cryptography, consensus mechanisms, platform and APIs.
The Blockchain app category also has two types: cryptocurrency-based solutions and non-cryptocurrency-based solutions.
For reference, you can consider the following numbers.
- Simple Projects: $5000 to $30,000
- Complex Projects: As high as $ 130,000
Blockchain Development Cost based on Industry:
- Healthcare: $55,000 to $100,000+
- On Demand: $40,000 to $80,000
- Social Media: $45,000 to $100,000+
- Public Sector: $70,000 to $100,000+
- Finance Sector: $60,000 to $100,000+
Miscellaneous Factors:
Different types of blockchain applications like DeFi, NFT, smart contracts, and cryptocurrencies can have an impact on the cost.
The more stages of app development, from prototyping to testing, the higher the cost
Hiring models like freelancer full-time employees can also affect the cost structure.
