Interviews with a prospective blockchain development company

While evaluating the developer, you should pay attention to the following areas:

1. Find out if a developer knows about basic programming concepts

When hiring a blockchain development company, it’s critical to ensure that the company you’re evaluating understands various ideas of programming languages. Some of the development concepts include C, C++, Python, etc. An experienced blockchain developer should also understand the following concepts: OOP (Object-Oriented Programming Structure), syntax,  Multi-Threading, and socket programming.

  • OOPS: OOPs denotes objective-oriented Programming Structures developed around the idea of objects. These objects are organized into classes, making it possible to group them. It’s possible to modify objects without interfering with other objects in the program. The object-oriented language enables updates to be performed any time when a need arises.
  • Syntax: Any blockchain developer should demonstrate profound knowledge of syntax programming language. In programming, syntax entails the principles that particularize the overall sequence of signals used to develop structured programs for the particular functionality of an app.
  • Multi-Threading: This is the ability of a computer processor in a multi-core processor to operate many threads or procedures simultaneously. Thus, the best developer should understand the installation of multi-threading in various kinds of applications.
  • Socket programming: The socket programming language helps a developer link two nodes, enabling them to interact with each other.

2. Find out if the developer understands the security needs of blockchain technology

The developer should understand the security needs of your blockchain project and use different encryption techniques to deliver it. An experienced developer should understand the concept of secure Hashing Algorithm, Encryption and Decryption, and private and public keys.

  • Secure Hashing Algorithm (SHA): SHA technology enables a developer to surmount multiple cyber-security risks and keeps information safe. The algorithm changes the information with the hash feature and comprises modular additions, bitwise, and compression roles. Because blockchain installs encryption protocols, a blockchain developer must have a thorough knowledge of encryption ideas.
  • Encryption and Decryption concepts: whereas encryption entails transforming data into unreadable text, decryption involves converting the unreadable information into legible text.
  • Private and public keys: the two forms of keys are either used to encrypt or decrypt information. Whereas public keys are accessible to each individual, private keys are confidential and accessible to their respective owner.

3. Inquire from the developer if they understand data structures

Understanding the concept of data structure is essential in software development. Some of the data structures that a developer should demonstrate an understanding of include: Linked List, Hash Table, and Acyclic Graph.

Data structures:

  • Linked List: This is a series of data elements linked together through pointers.
  • Hash Table: This data structure installs an associative array of info types, which locates keys to their corresponding values. A hash table can turn an index into multiple slots through a hash function, facilitating the location of the required value.
  • Acyclic Graph: It’s a bipartite graph without curves. The graph lacks recurring vertices and excludes ends and starting vertices.

4. Inquire whether a developer knows the basic concepts of blockchain

An experienced blockchain developer must understand the fundamental ideas in blockchain development. Here are the basics of blockchain development that a developer should understand:

  • Distributed Ledger Technology (DLT): This allows virtual information to be shared and replicated across different nodes. A blockchain development firm should know how DLT functions and how it should be applied in various kinds of blockchain.
  • Immutability: The concept of immutability means that something is irreversible. So, when information is put on a blockchain, no one can alter it.
  • Consensus: The consensus mechanism enables decisions, as blockchain lacks a central authority to govern it.
  • Token creation: Tokens are tradable virtual assets that reside on a blockchain. A skillful blockchain development firm should understand how to create these assets.
  • Smart contracts: These are virtual self-executing agreements that allow a quick exchange of shares, property, money, etc.  You expect an experienced developer to offer high-quality smart contract services.
  • Mining: Is the procedure of adding or validating settlements on the blockchain technology. Miners use their computational knowledge to create new blocks.
  • Decentralized applications (DApps): The developer you want to choose should understand the concept of DApps which are delivered on a P2P network of computers. Due to their decentralized nature, DApps lacks a central authority to monitor them.
  • Sharding: Sharding is a database division method used by blockchain developers to enhance scalability, allowing the system to execute more settlements per second. Through sharding, developers divide a company’s whole network into minute divisions called shards. Every shard has its own information, making it different and individualistic from the rest.
  • Public blockchain: A public blockchain network is a decentralized network where anyone can participate at any time. This network has nil restrictions and anyone can join and participate. Furthermore, a public ledger is visible to everyone, allowing them to participate in the consensus procedure. For instance, Ethereum is one of the public blockchains.
  • Permissioned blockchain: In a permissioned blockchain, each person can read the information on the network. However, specific players can mine or confirm settlements. In other words, permissioned blockchain presents an additional security layer, allowing specific individuals to perform particular actions. Examples of permissioned blockchains include Hyperledger Fabric, R3 Corda, and Hyperledger Sawtooth.

5.  Find out whether the developer knows the right tools to use

Developers of blockchain technology use multiple tools. The key ones include:

  • Composer: It’s an open-source tool to develop blockchain apps.
  • Explorer: It’s used to develop user-friendly web apps.
  • Remix:: You can use this tool to craft solidity agreements directly from the browser.
  • Metamask: This is essential when transferring virtual currencies from one wallet to another.
  • Etherscan: This is used to verify various digital agreements and all settlements happening on the Ethereum network.
  • Mist: Its role is to manage the transactions and assets in the Ethereum network.
  • Caliper: It’s used to evaluate the performance of a specific blockchain installation.
  • Bitcoin Blockchain Explorer: The tool provides in-depth information about BTC addresses, settlements, and blocks.
