10 questions to ask before hiring blockchain developers
Blockchain is widely considered one of the twenty-first century’s most revolutionary technologies.
With global spending on blockchain solutions reaching 4.1 billion USD, demand for remote blockchain engineers has skyrocketed. Experts predict that the blockchain industry will increase from USD 1.2 billion in 2018 to USD 23.3 billion by 2023.
If you’re looking to recruit blockchain developers from all around the world for your company, you’ve come to the right place. Here are the top ten things to ask when hiring qualified and talented remote blockchain developers.
What is blockchain technology, precisely, and how does it work?
Why are you inquiring about this?
This question will help you determine how familiar the candidate is with blockchain technology in general and how well they understand the key features.
Answer:
Blockchain is a decentralized digital ledger system that may store transactional data or cryptographically linked blocks. As a consequence, it is entirely safe, with a strong focus on transparency.
The advantages of blockchain technology are numerous, and here are a few of the more essential ones:
The use of Blockchain technology provides a high level of security.
- Decentralized: There are no centralized institutions or authorities that control the blockchain.
- Coin minting: Blockchain technology enables several different coin minting procedures.
- Immutability: Once data has been recorded on a blockchain, it cannot be changed or updated.
- Cost-effectiveness: Blockchain technology is both practical and affordable because there is no third party involved.
Why are tokens required for a Blockchain to function?
Why are you inquiring about this?
This question helps you analyze the candidate’s knowledge of the token market and ICO development and their experience working on blockchain development projects.
Answer:
The primary purpose of coins and tokens is to implement state transitions. When a user completes a transaction, this is known as a state change. On the other hand, money or tickets are transferred from one location to another.
A blockchain does not require money or tokens for technological activities. However, in their absence, another mechanism for maintaining chain states and validating transactions must be used.
What are the many types of records that may be stored on a Blockchain?
Why are you inquiring about this?
You may assess and rate the developer’s knowledge of blockchain technology. Also, be assured that the blockchain developer you choose for your company is the finest in the industry.
Answer:
The blockchain supports many data and records in various industries, regardless of your company’s size or style. As a result, if your business employs supply chain management, blockchain technology may be utilized to store enormous volumes of information.
The following types of records are supported by blockchain:
- Transactional records
- Medical care records
- Supply chain management records
- Personnel or employee files
- Documents Not Included
In a Bitcoin implementation, how does the process of encrypting transactions and blocks work?
What is it that you want to know about this?
One of the many things to check when hiring blockchain engineers remotely is if they have any expertise encrypting transactions and blocks, which the following inquiry can help you discover.
Answer:
A Bitcoin transaction’s blocks are all public and not encrypted in any way. A number called the block hash is utilized in this case to prevent modifications and maintain data integrity.
The block content is processed using the SHA256 hash algorithm during bitcoin implementation, and the resultant value is added to the blockchain.
What’s your take on the trapdoor function, and why is it crucial in Blockchain development?
Why are you inquiring about this?
To evaluate a potential blockchain developer, ask them this question. Know the experience with blockchain development and verify that the developer you employ has the competence you need for your project.
Answer:
The trapdoor function is frequently used in blockchain development to express addresses and private keys, which is necessary for public-key encryption.
The blockchain development function typically refers to a single-direction easy-to-compute role. Computing in the other direction, on the other hand, is complicated without particular expertise.
Is there anything that companies must do to use blockchain technology?
Why are you inquiring about this?
The inquiry will help you analyze the developer’s understanding of available resources and their experience with blockchain development projects when you hire blockchain engineers remotely.
Answer:
No, there is no such restriction on a company’s usage of blockchain technology. The required network, however, must be a peer-to-peer network that adheres to the mentioned protocols.
What are some of the commercial benefits of blockchain?
Why are you inquiring about this?
It allows you to assess whether the developer has strong analytical skills and manages large codebases.
Answer:
The following are just a few of the many benefits of blockchain for businesses:
- Thanks to blockchain’s consensus mechanism, businesses may profit from a consolidated dataset with fewer errors and better flexibility.
- Because business networks that employ blockchain technology have automatic contracts, businesses may benefit from cheaper costs, faster execution, and decreased risk.
- The adoption of blockchain technology enhances the trustworthiness and integrity of transaction data flow among participants.
What exactly is cryptography, and what is its purpose?
Why are you inquiring about this?
This question may be used to assess a candidate’s knowledge of blockchain cryptography and protocols and their ability to offer secure digital transactions and safeguard user identities.
Answer:
Cryptography is a collection of strategies for keeping data private. The fundamental objective of cryptography is to protect your data from tampering and unauthorized access. At the same time, it is being held and ensures a seamless transfer from sender to recipient.
The block of chains maintains a strict hierarchy thanks to cryptography. As a consequence, all records are verified and secured against unauthorized changes.
