All you need to know about blockchain

All you need to know about blockchain

Blockchain defined: Blockchain is a shared, immutable ledger that facilitates the process of recording transactions and tracking assets in a business network. 
An asset can be tangible (a house, car, cash, land) or intangible (intellectual property, patents, copyrights, branding). Virtually anything of value can be tracked 
and traded on a blockchain network, reducing risk and cutting costs for all involved.

Why blockchain is important: Business runs on information. 
The faster it’s received and the more accurate it is, the better. Blockchain is ideal for delivering that information because it provides immediate, shared and 
completely transparent information stored on an immutable ledger that can be accessed only by permission network members. A blockchain network can track 
orders, payments, accounts, production, and much more. And because members share a single view of the truth, you can see all details of a transaction end to 
end, giving you greater confidence, as well as new efficiencies and opportunities.

While Blockchain is a relatively new technology, there are already many career options available. Some of these are core Blockchain jobs that require specialized 
skills while others are more flexible. So check out these jobs now:

1. Core Blockchain Developer
Core blockchain developers are mostly responsible for developing the architecture of a blockchain system, how its protocols should be designed, the design of 
consensus protocol, and other high-level decisions and development related to blockchain technology. Blockchain software developers, on the other hand, use the 
architecture and protocols designed by Core Blockchain developers to build decentralized applications that run on blockchain technology.

2. Blockchain Application Developer
Blockchain Software Developers have a separate set of roles. These roles have nothing to do with consensus design or architecture of the system. Much like how a 
normal web developer uses the protocols and design structure set up by a core web architect to build web apps, blockchain software developers build decentralized 
applications or Dapps using blockchain technology. Their roles include:

3. Blockchain Project Manager
The Project Manager Blockchain is responsible for overseeing the Blockchain project team. This group is responsible for the enterprise’s blockchain database systems, 
cyber currency controls, and blockchain processing systems that form the basis of this initiative. This responsibility includes processing security, cyber currency 
management systems, resource monitoring, and reporting, and the development of specialized programs. The Project Manager Blockchain coordinates blockchain processing 
software issues with other IT organizations including applications and operations.

4. Blockchain Quality Engineer
A blockchain quality engineer is responsible for developing automation frameworks, manual testing, and testing for glitches and bugs. If any problems arise, 
they have reported the concern to the right department and ensured that the final product does not have any bugs. 

What are the Core Skills for Getting a Job in Blockchain?
While all the jobs in Blockchain are different, there are still some core skills that will enhance your chances of creating a career in this technology. Of course, some of 
these are critical if you want a job in core Blockchain or as a Blockchain developer but if you just need a job in the peripherals then a passing familiarity with these concepts is enough.

1. Cryptography
If you want to get a job in core Blockchain, you should obviously be familiar with cryptography. There are many concepts that you need to know such as public-key cryptography which 
is the basis of cryptocurrency transactions wherein it provides the security factor. You should also be familiar with cryptographic hashing which involves producing an output from 
the given input using the hash function.

2. Smart Contracts
Smart contracts are a fundamental part of blockchain wherein a contract is made between 2 parties without needing any intermediary. Smart contracts remove the need for a third 
party, and they are so successful in multiple industries because they save money and labor. So you should be very familiar with this concept to become a blockchain developer as
multiple languages like Viper and Chain code in Blockchain depend specifically on smart contract development.

3. Data Structures
Data Structures are the foundation of computer science, and they are also very important in Blockchain. In fact, each block in the Blockchain is a type of data structure where 
it contains the data that is connected to a unique 32-bit whole number called a nonce. So there is no doubt that you will work extensively with various data structures both to 
create Blockchain as a Core Blockchain Developer and also to implement it as a Blockchain Application Developer.

4. Blockchain Architecture
You should have a thorough knowledge of Blockchain architecture. This contains mainly 3 types i.e. Consortium architecture where the members of a group have authority and it is 
not totally decentralized, Private architecture where few people are part of a private system, and Public architecture which consists of a decentralized network. Popular examples 
of these three types of architecture are the Energy Web Foundation, Sawtooth, and Bitcoin respectively.

5. Web Development
If you are working as a Blockchain Application Developer, then you will be creating many web-based applications. In such a situation, it is very important that you have a thorough 
knowledge of web development. Most of the time, you will also need to create Blockchain dApps that people with no or little knowledge of Blockchain should be able to use so you 
should be proficient in web design and development along with Blockchain.

6. Communication Skills
If you are working more in the corporate or project management side of Blockchain, then you need excellent communication skills along with technical skills. As a project manager 
or a quality engineer, you should understand the development cycle in Blockchain and also be able to convey this information to your non-technical colleagues and supervisors that 
are in charge of Blockchain deployment in the company.

Conclusion
As Blockchain technology continues to evolve, so will its professional opportunities. The Blockchain is here with us to stay which means that Blockchain Expertise is to be in high 
demand for years and years to come. So whether you are a techie or not, a career in Blockchain is a new and exciting opportunity worth exploring.
