How to Become a Blockchain Developer : Skills | Roles & Responsibilities




Become a Blockchain Developer?

Nowadays Blockchain is one of the most emerging technology. Apart from that being the revolutionary technology in the present market. The information in its publicly available for everyone and each of the blocks of data is highly secured with multiple chains.

The Basic concepts of Blockchain are creating digital identities, tracking everything and monitoring supply chains. According to one of the social networking site (LinkedIn), Blockchain development is one of the most emerging jobs of 2018.

Blockchain developers are basically two types of developers:

1. Core Blockchain developers – To design architecture of Blockchain

2. Blockchain developers – Use the architecture and create applications

For both of the developers, we need some basic knowledge and became Blockchain developers.

Below skills are you should learn to become a Blockchain developer with simple concepts:


1. Data Structures:

This is a very basic concept to learn Blockchain. To the understanding of solid data structures concepts with algorithms because of Blockchain is quite complex to understanding and developing. Blocks are even secured and strong by Cryptographic techniques we need to Data structure concepts.

Mostly preferable concepts in Data structures are like LinkedList, binary trees, Mapping techniques, and graphs. As well as an upgrade one of best programming languages is Java, Python, C, and C++.

2.Cryptography:

After completion of Data Structures, concepts will go with Cryptography for public key encryption and decryption for digital signatures.  Basic knowledge of RSA and ECDSA concepts with solid knowledge of Mathematics.

3.Networking:

Blockchain developers need an idea on Networking concepts like peer to peer networks, routing, configurations, and topologies for a chain mechanism. For communication exchange information need to learn OSI model and Protocols is enough for Blockchain developing.

4.Distributes Systems:

The distributed system is an autonomous computer that is connected using the distribution environment for sharing resource data within a single network. It is for reliability and transparency in blockchain mechanism.

5.Smart Contracts:

Last but not least smart contracts are a major role in Blockchain developing. It is a program that runs on the blockchain once the transaction is done. Smart Contracts are unbiasedly enforced to increase blockchain capabilities.



Summary: Blockchain developers Roles and Responsibilities are to developing coding in C/C++ or any other programming language including web development with Cryptography and strong knowledge on Maths for tracing chains.

Hadoop Admin Vs Hadoop Developer




Basically in Hadoop environment Hadoop Admin and Hadoop Developer major roles according to present IT market survey Admin has more responsibilities and salaries compared to Hadoop developers. But we can differentiate below-mentioned points:

Hadoop Developer:

  1. In Big Data environment Hadoop is a major role, especially in Hadoop developers. A developer primarily responsible for Coding in Hadoop developer also the same kind of thing here developing like:

A)Apache Spark – Scala, Python, Java, etc.

B) Map Reduce – Java

C)Apache Hive  – HiveQL (Query Language & SQL)

D) Apache Pig  – Pig Scripting language etc.

2. Familiarity with ETL backgrounds for data loading and ingestion tools like:

A)Flume

B)Sqoop

3. Bit of knowledge on Hadoop admin part also like Linux environment and some of the basic commands while developing and executing.

4. Nowadays most preferably Spark & Hive developers with high-level experience and huge packages.

2.Hadoop Administration:

1. Coming to Hadoop Administration is a good and respectable job in the IT industry. Whereas, admin is responsible for performing the operational tasks to keep the infrastructure and running jobs.

2. Strong knowledge of the Linux environment. Setting up Cluster and Security authentication like Kerberos and testing the HDFS environment.

3. To provide new user access to Hive, Spark, etc. And cluster maintenance like adding (commissioning) node and removing (decommissioning) nodes. Resolve errors like memory issues, user access issues, etc.

4.Must and should knowledge on BigData platforms like:

A) Cloudera Manager

B) Horontworks Data Platform

C) MapR



D) Pseudo-distributed and Single node cluster setup etc.

5. Review and Managing log files and setting up of XML files.

6. As of now trending and career growth job.

7. Compared to Hadoop developers, Hadoop Admins are getting high salary packages in present marketing.



Summary: In the Bigdata environment Hadoop has valuable and trending jobs. And provide huge packages for both Hadoop developers and Hadoop administration. Depends upon skill set will prefer what we need for future growth.
