Technical skills required to start your journey as a Blockchain Developer
Now to be in the blockchain field, you must have the knowledge of basic blockchain technology with the new concepts evolving in the blockchain ecosystem. Here are a few skills that you need to learn and have in-depth knowledge for starting a career in blockchain technology.
Distributed Systems and Networking
To understand blockchain technology, you need to start from the start. Blockchain technology is a distributed ledger, so it is necessary to have an understanding of peer-to-peer networks. Also, you need to have knowledge about the Blockchain consensus mechanism, which is a core of blockchain. The most used blockchain consensus algorithm is Proof-of-Work (PoW) with bitcoin works, and the other one is Proof-of-Stake (PoS).
One of the most talked-about blockchain applications is cryptocurrency. Cryptography is the technology behind cryptocurrency. So having the basic knowledge of hash functions and good mathematical skills will do wonders for you in this field. Also, having an understanding of Block Ciphers. Authenticated encryption and message integrity are also a must.
As we know, Blockchain is a specific form of Database, and information is stored in the blocks where one block is connected to another. So, on the whole, you need to have the concept behind storing data in blockchain technology. Here, the database moves across the network called a distributed ledger, and the security is maintained with the help of cryptography. A blockchain developer must be aware of the practical working of the data structures like linked lists, hash maps, graphs, search trees, etc.
Advanced Programming Language
With the basic knowledge of programming language, you must also be familiar with some advanced programming languages. A list of some is mentioned below-
Become a Blockchain Developer
After acquiring the necessary developing skillset, you must know what type of blockchain developer you need to become. You can be a Blockchain Software developer or a core blockchain developer. Let’s find out what are their basic job roles and responsibilities.
Blockchain Software Developer
They have to build applications that are based on blockchain architecture and protocol. Blockchain software developer tends to create decentralized applications (DApps) and web applications. The Blockchain software developer manages all front-end and back-end development.
Roles of Blockchain Software Developer:
- Smart Contracts Development
- The Back-end and front-end designs development for DApps
- Supervising the entire DApps running stack.
Core Blockchain Developer
These developers focus more o the core part of blockchain technology, which involves designing the consensus protocol, security, and architecture of blockchain technology.
Role of Core Blockchain Developer –
- Designing blockchain protocols
- Consensus algorithm designing and managing security dor the network.
- Also, designing the blockchain network architecture
- Supervising the entire network
Knowing Smart Contracts
For automating transactions, smart contracts are used in blockchain technology. Smart contracts increase the Blockchain capabilities without any central authority. Blockchain developers need to audit and optimize smart contracts. It is essential to know the possibilities of smart contract execution. As a blockchain developer, make sure to execute the smart contracts only when they are expected. Smart contracts are created when there are specific conditions, and as soon as the particular condition is achieved, then the transaction is processed automatically.
Get familiar with Decentralized Applications
As a blockchain developer, you need to develop decentralized applications (DApps) using blockchain technology. There are several blockchain platforms that can be used in building DApps. Let’s learn some basic information about some popular blockchain platforms below:
Hyperledger: It is a permission private Blockchain that plays a key role in developing Hyperledger tools. You must know about two projects, namely, Hyperledger Fiber and Hyperledger Composer.
