But first let’s discuss – Why Solana is one of the top blockhain? Why is there high demand for Solana developers? What makes Solana development a competitive job?
Solana, an open-source project based in Switzerland but started in San Francisco in 2017, gained notoriety in 2021 as a possible Ethereum challenger. A multi-layered blockchain powered by the SOL token, which is similar to Ethereum, enables developers to construct apps on top of it, such as decentralised finance (DeFi).
In the summer of 2021, the market cap of Solana increased by 400%. The digital coin, which had only been released in April 2020, quickly grew in value in 2021, becoming one of the largest in the world in terms of market capitalization.
Given that Solana is one of the biggest blockchains in the world, the rise of the cryptocurrency corresponded with an increase in interest in NFTs, particularly DeFi. In that it can power decentralised apps, but more effectively, it is viewed as Ethereum’s main rival. For instance, Solana is rumoured to achieve transaction speeds comparable to a VISA transaction while consuming far less energy than Bitcoin miners.
The above statistics prove that Solana is indeed one of the most sought-after blockchain.

Solana Interview Questions for Beginners
1. What is the underlying tenet of blockchain technology?
Blockchain makes it possible to share information across users without duplicating the information.
2. What are the two categories of records found in the blockchain database?
Block records and transactional records make up these records. The finest part is that without using complicated methods, it is feasible to combine both of these data with one another.
3. What characteristics does Blockchain have?
The blockchain has four essential characteristics:
– Decentralized Systems
– Distributed ledger
– Safer & Secure Ecosystem
– Minting
– Decentralized Systems

– Safer & Secure Ecosystem
– Minting
4. Describe encryption. What part does it play in Blockchain?
Data protection is always important. In essence, encryption is a strategy that aids businesses in protecting their data. top blockchain interview questions in cryptography – Edureka Only parties with the proper authorization may access the encrypted data since it is encoded or modified to some extent by the sender before being transferred over a network. This strategy is helpful in blockchain since it merely increases the overall security and validity of blocks and aids in keeping them safe.
5. By blocks in blockchain technology, what do you mean?
The blockchain is a database of records. Blocks are used to hold these records. These blocks are connected to one another to form the chain known as the blockchain.
6. How does the Blockchain method identify blocks?
Every block in this online ledger essentially consists of transaction information, a time stamp, and a hash reference that serves as a connection to the block that comes before it.
7. Once data has been written in a block, can it be changed?
No, it is not feasible. The company just needs to delete the data from every other block if any changes need to be made. Data must be handled with extreme caution while utilising this strategy for no other reason than this.
Intermediate Solana Interview Questions
As a Solana developer, with experience you will be able to answer Solan interview questions for freshers with much ease. In this section we have collected some Solana tricky interview questions for you. This section will help you with the exact kind of Intermediate Solana Interview Questions that you may face in your job hunt.
8. Explain about the security of a block?
A robust cryptographic hash method secures a block or the whole blockchain. Every block has its own own hash pointer. The block’s hash identification will change if any of the block’s components are altered. As a result, it provides a high level of security. As a result, one should not be concerned about the safety or security of the data contained in a block.
9. What is a smart contract?
The negotiation or fulfilment of a contract can be digitally facilitated, verified, or enforced using a smart contract, which is a computer protocol. Without the involvement of other parties, smart contracts enable legitimate transactions. These transactions may be monitored and are final.
Smart contracts are designed to eliminate other transaction costs connected with contracting and to offer security that is superior to that provided by standard contract law. Different forms of smart contracts have been deployed in cryptocurrency.

10. Describe Merkle trees. What role do Merkle trees play in blockchain technology?
Each leaf node of a Merkle Tree, commonly referred to as a “hash tree,” is a hash of a block of data, and each non-leaf node is a hash of its child nodes.
The advantage of employing the Merkle Tree in blockchain is that a “light client” can merely download the chain of block headers rather than downloading every transaction and every block.
Additionally, a user need not download the full block in order to check the validity of a single transaction inside it. It is sufficient to download a set of the branch of this tree that contains this transaction. We examine the hashes that are currently ascending the branch (relevant to my transaction). If these hashes are accurate, we can be certain that this specific transaction took place in this block.

11. Describe a ledger. Is Blockchain a trustworthy ledger?
The blockchain is thought to be uncorruptible. Any malicious person acting alone is helpless. According to Augier, “to seize control of the network, an attacker would have to control more than 50% of its entire processing power.” “We hope that hypothetical situation is true, but we can’t be certain. Should that occur, the person would take all necessary measures to remain undetected. Not to mention the electricity needed to keep the computers running so that the blockchain system can function.
12. Why is the blockchain a reliable method?
Blockchain is reliable for a wide range of uses. The first thing that springs to mind when thinking about its open-source nature is its interoperability with various commercial software. Its safety is the second consideration. The creators took extra care to staying up to date with protection because it was intended to be used for online transactions. Regardless of the matter the sort of company one owns, blockchain will be helpful.
13. What does blind signature mean and how is it helpful?
In a blind signature, the contents of the message are concealed (blinded) before the signature is made. The resultant blind signature may be publicly authenticated against the original, unblinded message, just like a regular digital signature.
In privacy-related protocols, blind signatures are frequently used when the signer and message author are different people. Digital currency systems and cryptographic voting systems are two examples.

14. What Sets Proof-Of-Stake (Pos) And Proof-Of-Work (Pow) Apart?
The two most often used consensus algorithms, PoW and PoS, may be distinguished based on how they work. PoS does not require as many resources as PoW does. Other notable distinctions include the requirement for a large amount of compute power in PoW as opposed to none or very little in PoS. In comparison to PoW, PoS is more economical and completes tasks faster.
Advanced Solana Interview Questions
This section contains some advanced interview questions on Solana . This section also explores a few Solana coding Interview questions. You may practice the common Solana programs which the interviewer often asks..
15. Explain about the Genesis Block?
The genesis block is the very first block in any blockchain. Starting at any block and moving backwards along the chain will get you to the genesis block. The client software’s static encoding prevents changes to the genesis block. Each node can recognise the genesis block’s structure, hash, fixed creation time, and individual transactions. As a result, every node has a reliable “root” that can be used to create a trustworthy blockchain.
16. Describe the requirement for tokens for a blockchain's operation
Changes between states are implemented using coins or tokens. When someone transacts, there is a change of state and the location of the coins are changed. On addition, transactions may contain extra data, and the only method to modify data in a blockchain that is by definition immutable is through a change in state.
Technically, a blockchain may function without coins for its core functions, but without them, a different mechanism must be used to maintain chain states and validate transactions.

17. What is RSA algorithm?
Modern computers employ the RSA (Rivest-Shamir-Adleman) method to encrypt and decode communications. This cryptography algorithm is asymmetric. Asymmetric implies the existence of two distinct keys. The fact that anybody may obtain one of the keys gives rise to the term “public key cryptography” for this method. The second key needs to be kept secret. The approach is based on the fact that it is challenging to identify the elements of a big composite number.
A public key and a private key are used in RSA. Everyone has access to the public key, which is used to encrypt messages. Only the private key may be used to decode messages that have been encrypted using the public key.

18. Why is a trapdoor function necessary for blockchain development, and what does it do?
A function known as a trapdoor function is one that is simple to calculate in one way but challenging to compute in the opposite direction without particular knowledge. Trapdoor functions are frequently used in blockchain development to symbolise the concepts of addresses and private keys since they are crucial for public key encryption.
19. How Does Secret Sharing Work? Does it improve blockchain technology in any way?
The importance of security in digital transactions is well-known. The strategy intended for the same is secret sharing. It is a method in blockchain technology that separates confidential or private information into smaller components and sends them to network users.
The original information may only be merged when a person who has been given a share of the secret agrees to do so. The blockchain technology has a number of advantages in terms of security.

20. Could you define off-chain transactions?
The transfer of value away from the blockchain is referred to as an off-chain transaction. Off-chain transactions depend on additional means to record and authenticate the transaction, in contrast to on-chain transactions, which modify the blockchain and depend on the blockchain to establish their validity.
21. Is there a network specific requirement for deploying blockchain technology?
There is no prerequisite for utilising it. However, in accordance with the relevant protocols, the network must be a peer-to-peer network. It quickly verifies the new block and enables businesses to keep up with the pace in this area without spending money on outside programmes.
22. What are the steps needed to implement the Blockchain project?
There are a total of six phases in this procedure, and they are as follows:
– Requirement identification.
– Screen ideas consideration.
– Project development for Blockchain
– Feasible study on the security
– Implementation
– Controlling and monitoring the project
