General blockchain interview questions

Blockchain technology is at a nascent stage and it ideal time to enter it as a developer. If you are planning to start a blockchain career, you need to focus on acquiring the required skills and certifications. In this blog, we focus on general blockchain interview questions that are common during blockchain developer interviews.

1. How does blockchain work?

Blockchain is a combination of 

• Cryptography keys 
• a peer-to-peer network containing a shared ledger, 
• Method of computation that stores and record network transaction

When a new transaction is entered into the blockchain. The transaction is transmitted to a network of peer-to-peer computers scattered all over the world. The network of computers mathematically solves the equations to confirm the validity of the transaction. A block is created after the transaction is confirmed. These blocks are chained together to create a history of all the transactions, thus creating a permanent record. The blockchain transaction is complete.

2. How two blocks of blockchain are related to each other?

According to Wikipedia, a blockchain is “a distributed database that maintains a continuously expanding list of ordered records, called blocks,” which are “connected using encryption. Each block includes transaction information, a timestamp, and a cryptographic hash of the one before it. A blockchain is a decentralized, distributed, and open digital ledger that is utilized to log transactions across numerous computers in a way that prevents the record from being changed retrospectively without changing all succeeding blocks and obtaining network consent.

3. What is mining?

Mining is the process of adding transactions to the distributed ledger in a blockchain. Though the term is primarily associated with Bitcoin, other blockchain technologies also use mining. Bitcoin miners who run mining operations are rewarded with Bitcoins. Miners create a hash of transactions that are difficult to counterfeit thereby maintaining the integrity of the blockchain without requiring a central system. Mining requires a powerful CPU, has higher electricity requirements, and generates more heat than a normal computer, it is often done with a specialized computer.

4. What does a ledger in the blockchain do?

A public ledger refers to the ancient method of maintaining records that was used to track news, analysis, and prices of agricultural commodities. The ledger was available for general viewing and verification. The ledger in the blockchain keeps track of each participant’s anonymous identity, their balance, and the history of legitimate transactions executed between the network participants. The public ledger is available for general viewing and verification. Ledger. There is no central authority or viewer that can view the details of the participants, participants thus maintaining complete privacy.

5. Which set of features of blockchain ensures business network trust?

Features of blockchain ensure business network trust is – 

• Immutable – Blockchain networks are permanent and cannot be altered. 
• Distributed – All members within the network have a copy of the ledger ensuring complete transparency.
• The decentralized – blockchain network is decentralized or there is no governing authority to make decisions or oversea them
• Secure – All the records are individually encrypted. 
• Consensus – Every blockchain has a consensus to assist the network in reaching choices quickly and impartially.
• Unanimous – All members have to agree to the validity of the record before they can be added to the network.
• Faster Settlement – When compared to the conventional banking system, blockchain has a faster settlement.

6. How do smart contracts work? Name a few smart contract platforms you have used.

Contractual parties need to finalize the terms and conditions of the contract. After finalization, the terms and conditions of the contract are translated into a code. the code contains a variety of conditional statements that outline several circumstances for a potential future transaction. t is copied across the blockchain’s users and saved in the network. The required transaction is carried out if a condition of the contract is met and has been confirmed by every user of the blockchain network. Some of the smart contract platforms I have used are –

• Ethereum
• Hyperledger Fabric
• NEM
• Stellar
• Waves

Cryptography interview questions

As we mentioned before, cryptography is the building block of the blockchain. As a blockchain developer, you should have a clear understanding of how cryptography works. In this section, we focus on cryptography interview questions that can be asked of blockchain developers. These questions can be used by businesses when they want to hire a developer on a full-time or contract basis.

1. What is cryptography?

Cryptography is the process of securing data and preventing illegal access. Cryptography is employed in the blockchain to safeguard transactions between two nodes in a blockchain network. The two main ideas in a blockchain are cryptography and hashing. In a P2P network, messages are encrypted using cryptography, and a blockchain’s block information and link blocks are secured using hashing. Cryptography focuses on the security of participants, transactions, and precautions against double-spending. It safeguards blockchain network transactions. It ensures that only authorized people can read, acquire and handle the data. 

2. What are Secret Key Cryptography and Public Key Cryptography?

Public key cryptography (Asymmetric key encryption) is a method that uses two separate keys for encryption and decryption while secret key cryptography (symmetric key encryption) uses a single key for encryption and decryption. Public key encryption is used for short messages while secret key cryptography can be used for longer messages.

3. What are the objectives of cryptography?

Cryptography is a method of using data security to prevent illegal access. It is employed in the blockchain to safeguard transactions between two nodes in a blockchain network. It focuses on the security of your transactions, and precautions against double-spending. It aids in safeguarding various blockchain network transactions. Cryptography makes sure that only those people may acquire, read, and handle the transaction that is intended for them.

4. What is SAFER?

James Massey one of the creators of IDEA, was principally responsible for creating the SAFER (Secure and Faster Encryption Routine) family of block ciphers of Cyberlink Corporation. The early SAFER K and SAFER SK design both use encryption, but their round counts and key schedules are different.

5. What is the difference between Hashing and Encryption

The difference between Hashing and Encryption are as follows –

• Hashing is the method to transform information into a key or shorter fixed value that serves as a representation of the original data. Encryption is the technique of secure encoding data so that only an authorized user who is aware of the key or password can retrieve the original data, leaving everything else as useless information.
• Hashing is used to index and retrieve items from a database and it happens quickly. Encryption is used to change data to keep it hidden from others.

p2p interview questions

P2P is an integral part of blockchain technology. With blockchain technology becoming popular and new job openings coming up daily, it is important to be familiar with different parts of blockchain technology to land your dream job. This section contains some key p2p interview questions and their answers that will help you ace your interview. 

1. What is a P2P Network architecture?

P2P Network or peer-to-peer network architecture computer network station where every workstation or node has the same capabilities and obligations. The P2P model is frequently compared with the traditional client/server architecture where some computers are dedicated to serving others. In a P2P network computer frequently acts as server and client and is responsible for sending and receiving data, with bandwidth and processing shared among all users.

Such a decentralized network is less prone to systemic failure and uses resources more effectively than traditional networks. P2P networks are utilized by Bluetooth-enabled devices and Internet-based communication services, although online file sharing has significantly fueled development. Each computer functions as both a server and a client in a peer-to-peer (P2P) network, sending and receiving data, with bandwidth and processing shared among all users.

Such a decentralized network is less prone to systemic failure and uses resources more effectively than a traditional network. Electronics powered by Bluetooth and Internet-based communication services utilize P2P networks.

2. How does a P2P network work?

A peer-to-peer network lacks a central authority, instead, every node (peer) is connected. There is no hierarchy and the network nodes are connected by a mesh network with a “flat” topology. Peer-to-peer networks are open, decentralized, and robust by nature. Since nodes provide and consume services simultaneously, reciprocity acts as the driving force behind participation.

Each node on the network works as a server and client to other computers or nodes on the network. The node in a decentralized system functions as a server, downloading files and sharing them with other nodes. The P2P network’s speed, security, and effectiveness are due to the ability of a node to simultaneously conduct sharing and receiving tasks. A P2P network works best when there are many active nodes in the blockchain network.

Ethereum interview questions

There is a huge demand for Ethereum developers in the market. Ethereum is one of the biggest blockchain platforms available right now. Many businesses are looking for Ethereum experts and it is the ideal time for a blockchain developer to find employment. We will go over the top Ethereum interview questions in this section.

1. What is the difference Between Bitcoin and Ethereum Blockchain?

Bitcoin is a decentralized digital currency that can be transferred on a peer-to-peer network. Ethereum is a software platform that runs on the Ethereum blockchain technology. Bitcoin was invented hoped to replace national currency while Ethereum hoped to leverage blockchain technology for maintaining a decentralized payment network and storing computer code. Ethereum smart contracts are more flexible than Bitcoin smart contracts. Smart contracts are written for Bitcoin and use Script and clarity while Smart contract use Solidity and Viper.

EEA hopes to build, promote, and support the best practices in Ethereum technology, standard, and architecture and is capable of handling real-world applications.

3. What is Wei?

Wei is the smallest denomination of ether used on the Ethereum network. One ether = 1,000,000,000,000,000,000 Wei (1018) or one Wei is one quintillionth of an ether. Wei and other Ether denominations will help express tiny value transactions, particularly small ETH that is frequently used for transaction fees or when determining a transaction gas limit.

4. How are Ethereum tokens are created?

Ethereum tokens or also cryptographic tokens are fungible digital assets that are built on top of the blockchain. Numerous digital assets are stored on the blockchain; the block explorer and analytics website Etherscan.io alone includes over 900 prominent projects based on the popular ERC20 token standard. Ethereum tokens are created by deploying smart contracts. There are over 400,000 ERC20 token contracts but one native token – Ether (ETH). The Ethereum network produces ETH to compensate miners for their efforts in adding blocks to the blockchain. Since it is needed to pay the gas fees necessary for each transaction, it is essential to the platform.

1. What is Solidity?

Solidity is a comparatively new computer language that is growing rapidly. The Ethereum network team worked to create Solidity specifically for constructing and designing smart contracts. Solidity is an object-oriented language. We use it to create smart contracts to implement business logic and create transaction records for the blockchain system. It helps to create machine-level code that can be compiled on the Ethereum Virtual Machine (EVM). Solidity is similar to C and C++ and has concepts like variables, functions, classes, and arithmetic operations. Solidity is currently used extensively on Ethereum and other blockchains like Monax

2. How is Solidity different from other programming languages?

Most programming languages are interpreted just in time. Solidity is a high-level programming language that gets compiled and deployed on the blockchain that understands the Ethereum virtual machine. After you compile the code and it is deployed to run as a smart contract and anyone can interact with it. The programming language run either on your browser or computer while Solidity can run on any computer on the Ethereum blockchain. 

3. What is an enum?

Enums are methods for defining user-defined data types and are typically used to give names of integral constants to improve the maintenance and readability of the contract. Enums limit the variables to one of a few preselected values, these values of the enumerated list are called enums. Enums help to reduce the number of bugs in the code.

4. Name the tools that can be used for testing Solidity codes.

Since Solidity contracts are immutable we must check the security of the smart contract before they are deployed on the blockchain. We require time and knowledge to carry out the audit and this can be complicated. Several tools can be used for testing Solidity codes, the top ones are – 

• Slither 
• Security
• SmartCheck
• Oyente
• Mythril

5. A solidity file can contain how many smart contracts?

One Solidity file can contain several contracts, but all contracts within a file share a namespace. Using multiple smart contracts can provide more security to projects. You can create contracts within or nestled contracts to limit what a user can do and what they can call.

Hyperledger Fabric interview questions

Hyperledger Fabric is an open-source platform used to create blockchain applications. If you are applying for the position of blockchain developer you may be asked questions on Hyperledger Fabric. In this section we have focused on Hyperledger Fabric interview questions, you can increase your chances of getting employed by impressing the hiring manager with your responses to these questions.

What is Hyperledger Fabric?

The Linux Foundation launched the open-source, permissioned blockchain system known as Hyperledger Fabric in 2015. It is a general-purpose, modular framework that provides distinctive identity management and access control features. It is used for a range of business applications, including trade finance, loyalty and rewards programs, track-and-trace of supply chains, and clearing and settlement of financial assets.

How do transactions work in Hyperledger Fabric?

Businesses use Hyperledger Fabric to ensure quick and smooth transaction flow. Hyperledger Fabric performs the transactions using the execute-order-validate method. 

• When the client wants to start a transaction, they use the client application to send an application to the SDK. SDK changes the transaction request into a transaction proposal that is sealed with the specific cryptographic signature of the client. The transaction proposal is subsequently forwarded by SDK to peers who are in charge of endorsing it following the endorsement rules.
• The endorsed peers verify the transaction proposals. After verification, the peers start the chain code proposal specified in the proposal. 
• Before submitting the transaction, the target peer confirms that the proposal responses are identical.
• The target peers broadcast the transaction message to the ordering services. The transaction contains the Channel ID, read/write settings, and a signature from each endorsing peer.
• After the transactions are validated, they are added to the ledger in the shape of a block.

What is Kafka used for?

Kafka is used for real-time streaming data pipelines and applications. A streamlined application consumes streams of data, and a data pipeline consistently processes and transports data from one system to another. For instance, Kafka would be used to ingest and store streaming data while sending reads to the apps driving the data pipeline if you wanted to build a data pipeline that ingests user activity data to measure how people use your website in real time. Kafka is used as a massage broker solution that process and mediates communication between two applications. 

In this article, we are going to discuss the technologies that blockchain professionals use. We will let you in on the technologies that blockchain professionals use to develop and implement blockchain software solutions.

From cryptocurrency to NFTs, IoT, and smart contracts. Blockchain developers are reshaping the face of the digital industry. Many aspiring programmers, just like seasoned software developers are turning towards blockchain development in the last decade. Even though this technology is not new anymore, it still raises questions with the general public and IT professionals, alike. One of the most common questions that circulate in the online world is related to the basics of blockchain development. 

Java

Ethereum, NEO, Hyperledger, and a series of other similar projects have strong use for Java programming language. Java is easy to use, and it’s not constrained to a single platform. Many Java users prefer Macbooks for working and often complain about viruses, so as it already mentioned in the article, there are some ways to prevent harm. So, the blockchain industry is versatile so it’s beneficial for programmers to use Java. Another important aspect of Java is multithreading. It secures optimal CPU usage, allowing more flexibility for programmers. The coding can be long and intricate since Java syntax is wordy. However, it offers a high level of security at the same time.

The biggest advantage of Java for programmers is WORA. This stands for “Write once, run anywhere” code. Thanks to WORA, programmers are not tied to a single platform. 

C++

This is an ancient programming language. However, it is still very actual and popular among programmers. The most notable advantage of C++ for blockchain is its OOP nature. Object-oriented programming features such as Run-Time polymorphism and function overloading make C++ more practical than other languages. This language gives programmers the ability to manipulate data seamlessly. Although it was invented way back in 1985, C++ is the pillar of Bitcoin, Ripple, Stellar, and many other notable projects.

This programming language is both object-oriented and procedural, which makes it extremely powerful. Moreover, it’s much faster than Java, which makes it even more popular among professionals.

Ruby

Yet another programming language on our list that provides programmers with cross-platform capabilities. Professionals value these types of features for their high flexibility and efficiency. Moreover, Ruby lets developers use third-party APIs and plugins for their projects. This is especially useful for complex projects. It simplifies the development process so it’s easy to meet the deadline. 

Ruby is a programming language famous for its sizeable memory allocation properties. This gives apps the chance to carry out all the necessary processes without issue thus making popular among blockchain professionals.

One of the most popular programming languages of today is also present in blockchain development. Python is widely known for its short code, which makes it easy to use. It benefits blockchain development thanks to its open-source nature. This gives programmers access to a series of different resources and plugins. As a result, they can develop versatile blockchain projects with ease. Programmers can work across different platforms, so cooperation is very easy.

Python is widely used in different fields of software engineering. What makes it popular among blockchain programmers the most is its GUI. This feature lets software engineers save time during project development. Moreover, this language executes one line at a time. Therefore, debugging and error scanning are seamless to perform. 

Solidity

The final item on our list is a programming language developed especially for blockchain programming. It’s relatively easy to master and use, which makes it a flexible solution. Solidity is a statically typed looping programming language designed for smart contracts. It is primarily built for smart contracts based on EVM. 

Although it’s made for smart contract development, there are a few downsides to this technology. The most notable Solidity drawback is its rigid nature. You can’t add new functionalities or change the smart contract once it’s made using this language. There is no single list of weak spots for Solidity. If you look for vulnerabilities, you have to search through different sources. Nevertheless, this programming language provides a safe, stable, and precise smart contract development environment.

Conclusion

The blockchain industry is worth billions and attracts investors from all over the world. Implementation of blockchain solutions is visible in finance and business. Although, it’s yet to reach its commercial peak. If you’re looking to start a career in blockchain development, the technologies we listed in this article are a good starting point. From all-around C++ to specific usability of Solidity, these were the five technologies that blockchain professionals use the most.

 

How much does it cost to create an nft

NFTs or Non Fungible Tokens are said to be one of the convenient ways to propagate your business into the virtual world. Yet despite its popularity, the concept is still new. The most common question among many is how much does it cost to create an NFT. In this article, we will be discussing this topic in detail.

What does minting NFT mean?

Minting NFT meaning – using tokens to create investments in the form of digital products or real-world assets like art, property, music, and so on. Unlike cryptocurrencies, NFTs are non-fungible and cannot be exchanged for another NFT. They are recorded in the blockchain as a unique cryptographic entity. The greatest advantage is that they are unique and eliminate the need for the involvement of intermediaries in the buy and selling of assets. You need to have a profile and a crypto wallet before proceeding with minting NFT.

How do you create an nft

The second part of the article on, how much does it cost to create an NFT, is to understand how do you create an NFT.

The steps for creating and selling nft are:

1.  Create a unique digital asset 
2. Set up the crypto wallet and NFT marketplace
3. Create the metadata by uploading your digital asset file to the Marketplace
4. Display the NFTs in the Marketplace so that people can purchase them

What is the cost of creating an nft?

The cost of creating an NFT varies between USD 0.05 and USD 150. Various factors affect the cost to make NFT like listing fee, blockchain cost, gas fee, and marketplace account fee.

Among the blockchain platforms used to create NFT, Ethereum and Solana are the most common and expensive. Ethereum uses the Proof of Work or PoW technology whereas Solana uses Proof of Stake PoS and Proof of History, PoH technology.

How much do NFTs cost?

The next important topic in response to the question – How much does it cost to create an NFT – is to understand how much do NFTs cost.

Usually, if you are looking for minting a standard NFT, then the cost varies between USD 1 and USD 1000. Sometimes the cost is more, depending on the blockchain platform being leveraged. Some wallets even charge money to open an account which may range from USD 70 to USD 120. Let us now try to understand the determinants that comprise the cost of NFT minting.

NFT gas fee

The NFT gas fee is the price that the users need to pay for any kind of transaction in the blockchain platform – listing the NFT, minting, purchasing NFTs, accepting the bids, and ownership transfer. The fee amount is ascertained as per the blockchain demand while initiating the transaction.

Account Fees at NFT marketplace

Another determinant of the minting cost is the account fees. It is basically a one time fee that the users need to pay. Before minting NFTs, one must set up a Marketplace account and then integrate the crypto wallet into the account. This activity demands a fee which is essentially the cost that is paid to the NFT marketplace for establishing the prerequisites. Polygon is the cheapest NFT blockchain platform that allows the free creation of accounts. 

NFT trading price or listing fee

The third determinant of NFT minting cost is called the listing fee or the NFT trading price. One of the steps for creating NFTs is to list them in the marketplace for trading. It is the activity that helps initiate the buy and sell of NFTs in the market. The fee which is charged for listing the NFTs for trading is the listing fee, comprising of the cost to create NFT.

How much are gas fees for NFT on different platforms

In the earlier sections, we have discussed gas fees and its implication. Now coming to the question of how much are gas fees for NFT? A very important point is how much does it cost to make an NFT. Well, the gas fees may alter depending on the demand and supply. It also depends on the complexity of the transactions, the network traffic, and the price of the related cryptocurrencies.

The typical gas fee on the Ethereum platform is 0.0021 ETH or 21,000 GWEI. You may also end up paying higher gas fees if the transactions occur fast. 

Can you make an NFT for free?

The answer is Yes if you want to know, Can you make an NFT for free? Certain platforms provide this facility like OpenSea and Rarible. They permit creating NFTs on the Ethereum platform for free. This is important information when you trying to seek an answer to the question of how much does it cost to create an NFT. Basically, the idea is to create the NFT and make it available for purchase without the need of being written to the blockchain.

What is lazy minting?

The above concept where NFTs are created for free is called lazy minting. The users do not have to pay any gas fees for minting their NFTs. The NFT is available off the blockchain platform and is minted only when it is purchased or the sale takes place. The gas fees are essentially rolled over to the transaction which does not mandate the buyer to pay any fees or NFT token cost. It is a deferred transaction where the gas fees are paid later and are passed to the buyer.

What is gasless minting?

Gasless minting is similar to lazy minting on the terms that users do not have to pay to mint an NFT. However, there is a slight difference between the two in the sense that the token is available immediately in the blockchain as per the decentralized mechanism. This is advantageous as the buyer does not have to mint the NFT after the purchase. Users can unique items to their wallets without any hassle of extra costs.

Now coming to the last part of the article on how much does it cost to mint an NFT.

Tips reduce the Cost of Creating NFTs

Here are some tips to reduce the cost of creating NFTs:

1. Leveraging the marketplaces which offer lazy minting or gas minting opportunities and the best ones among them are OpenSea, Rarible, Polygon, and Mintology.
2. If you can wait, then transact during the weekend as at that time trading is less and hence reduced gas fees
3. If you are ok to wait for an undefined period when the prices are low, then it is a good option for those who do not want to spend much on NFT creations

Do NFTs go up in value?

What are Solana smart contract?

Solana smart contract can be broken into two parts – the Solana network and smart contracts. The network features smart contract and developers can create Web3 projects and dapps that are supported by the Solana blockchain. Solana uses a hybrid consensus process that combines proof-of-history (PoH) and proof-of-stake (PoS) (proof-of-stake). Solana is able to keep transaction speeds high and prices low by utilising the two techniques. The focus on speed and scalability also makes Solana programming faster and more cost-effective than other rivals.

 

Ethereum blockchain

Ethereum blockchain was created to power thousands of decentralised transaction (ETH).  The blockchain is used for building decentralized apps and smarts contracts. Ethereum is designed to be scalable, programmable, secure, and decentralized. There are no restrictions on what the users can do to promote creativity. The network interactions or transactions are stored on the Ethereum blockchain. Before committing them to the network and serving as a digital ledger or transaction history, miners validate these blocks. Proving transactions by mining is referred to as a proof-of-work (PoW) consensus technique.

What is Ethereum market cap?
