6. What is the importance of Solana ecosystem?
The Solana ecosystem includes different projects such as dApps, NFT collections, and tools tailored to the Solana blockchain. Every list of Solana interview questions and answers focuses on how the Solana ecosystem showcases the capabilities of Solana network. It can help developers and users with easy access to different services and applications.
7. Does Solana help in improving scalability?
The interview questions on Solana also draw attention to Solana’s ability to improve scalability. Solana uses different features for offering scalability, including the unique consensus mechanism with the combination of Proof of History and Proof of Stake consensus. You can also answer such Solana interview questions by using techniques like parallel processing and sharding. The features help Solana in managing a large number of transactions per second with low latency.
8. What do you know about block finality in Solana?
Block finality is one of the essential concepts that define the functionalities of Solana blockchain. It denotes the time at which a block is considered completely irreversible. Solana can achieve faster block finality within a few seconds, thereby implying that transactions become immediately immutable on Solana blockchain.
9. How do clusters contribute to the architecture of Solana?
Clusters are also an important highlight in the most popular Solana interview questions about the basic concepts. Clusters are the smaller subsets of nodes that work in independent processing of transactions. The primary role of the smaller subsets is the distribution of the network’s load and contributing to decentralization by enabling more validators to participate in the network without compromises in performance.
10. What are the benefits and limitations of Solana?
You should also prepare for questions about the advantages and setbacks of Solana as compared to Ethereum blockchain. Any Solana interview questions list would be incomplete without references to Solana’s advantages and limitations. Solana offers prominent benefits, such as low transaction fees, higher throughput, scalability, and faster block finality. On the other hand, it is new to the blockchain landscape and has a smaller developer community.
