How To Hire A Blockchain Developer For Your Company

The latest blockchain technology was revolutionary, and the outbreak of this technology created a great demand for blockchain developers. The expectations from the blockchain developers were high to cope with the challenging tasks of established and start-up organisations. Hiring a blockchain developer for the company was a challenging task, and it includes several responsibilities.

Given below are the top skills that a good blockchain developer should have.

Top Skills a Blockchain Developer should Possess

1. Good knowledge of basic programming skills.

Blockchain developers should have basic programming knowledge in C, C++, Javascript, Python, Solidity, Go, Node JS, and Java.

The experienced and more talented blockchain developers should also be an expert in the following programming concepts:

  1. Syntax of the programming language

For any computer programming language, syntax is essential to run the programming successfully. Syntax refers to the set of rules with specific symbols to develop the structured program, which can be used for any functionality of the computer software.

Blockchain developers must know the proper syntax for all the required programming languages. For example, they should see the syntax of loops, while loops, logical operators, arithmetic operators, switch statements, and many more.

  1. OOPS Concept

OOPS refers to an object-oriented programming structure, Here the concept is based on the objects and organized accordingly. The objects are categorized into classes which allow each object to be grouped.

With the help of the OOPS concept, the blockchain developers can update any object without altering any other object. So the knowledge of the OOPS concept is required for the blockchain developers.

  1. Multi-Threading Concept

Mult-ithreading is the concept of concurrently running threads or pieces of the program to utilize the CPU. Blockchain developers must have strong knowledge to implement multithreading concepts in blockchain software development.

  1. Socket programming skills

Socket programming is used to connect the two nodes in the network. It helps to communicate with each other. When it gets combined, the server also creates the socket program from the other end to get connected with the client.

The blockchain developer skills should include good knowledge on socket programming.

2. The developers should have a strong knowledge of encryption/decryption and security concepts

The blockchain is based on encryption and decryption techniques to securely transfer the data over the network. So before you choose to hire a blockchain programmer, you need to confirm whether they have complete knowledge about encryption/decryption and security concepts.

Blockchain developers should know the following concepts:

  1. SHA-Secure Hashing Algorithm

It is an algorithm to maintain the data in a secure place. It is used for cybersecurity issues.

  1. Encryption and Decryption

Both are the cryptography techniques used to encrypt and decrypt the data while transferring over the network

Encryption:-Converting the plain text to cipher text or unreadable text

Decryption:-Converting the cipher text back to plain text at the receiver end

  1. Public and Private keys

These are keys used for encryption and decryption methods. Public keys are keys that everyone can access, but the private key is accessible only to the respective receiver or the owner. The encrypted data with a public key can be decrypted only with the respective private key.

3. Blockchain developers should understand data structures

The blockchain developers must understand the data structure concept. It is the main key to software development. Below are some of the important data structure concepts which are a must for the blockchain developers

  1. Linked List

A type of array in the data structure concept where the data are connected to each other via pointers.

  1. Hash Table

The data is stored as an array with the index value in the hashtable. Here the data is accessed easily with the index value.

  1. Acyclic graph

A graph without cycles is known as the Acyclic graph

4. Ensure that the Developer is well versed with the basic terms and concepts of blockchain

The blockchain developers must know the basic terms and concepts of blockchain. Below are some of the important concepts/terms of blockchain that are must in blockchain developer skills.

  1. Crypto tokens

The digital assets over the blockchain network are called crypto tokens. These tokens can be traded or exchanged over the crypto platform. The blockchain developer should know how to develop the tokens.

  1. DLT- Distributed Ledger Technology

The data is shared over the network rather than maintained at a single location. This is called DLT. The blockchain developers should have an idea of how the DLT works and should also know about its implementation.

  1. Immutability

Immutability is a blockchain term, which means the data recorded on the blockchain can never be altered or changed. To update the data, new events need to be added to the blockchain.

  1. Consensus

It is a decentralized network, so the decision making lies on the consensus mechanism. It is a type of agreement where all the members need to have the mutual decision to add any block to the network.

  1. Smart Contract

A digital contract between the two parties without any third party to share the money, property, or exchange anything based on the agreement on the blockchain. The solidity programming language is used to develop smart contracts on platforms like Ethereum platform

  1. DApps

DApps refers to Decentralized applications which use P2P network

  1. Permissioned Blockchain

Only the permissioned members can verify or mine the transactions and all members can read the data on the records.

  1. Public blockchain

All members have access to read and write the data on the records.

5. The blockchain developers should have strong tool knowledge to build the blockchain applications

Below are some of the development tools in which the blockchain developers should have hands-on experience.

  1. Metamask
  2. Composer
  3. Explorer
  4. Etherscan
  5. Remix
  6. Caliper
  7. Mist
  8. Bitcoin BlockExplorer

6. How to find the right blockchain developers

Once you have identified the skillset for the blockchain developers, you should know where to search for the blockchain developers. Not only in the job portals or Linkedin, but you can also find them in any social media or community.

Below are some of the important things to be considered while looking for the right team of blockchain developers

  1. Analyze the industry experience and the achievements of the company
  2. Brands or clients that have supported to build blockchain applications
  3. Enquire about the team strength, any different domain experience, and time zone supported
  4. Review the customer feedback and rating about the blockchain developers
  5. Enquire about the software development process they follow and analyze whether it is the latest software development process, such as Agile, Scrum, etc
  6. Check whether they have an in-house team or an offshore team, which helps to identify the quality of their work.
  7. Check whether they have any portfolio on blockchain and whether they worked on permissioned or public blockchain
  8. Enquire how they support from the beginning of the software development process to the end phase or deployment phase of the blockchain application
