These blockchain questions are coming at your interview!!
Blockchain is one of the hottest topics in the field of digital technology. Every aspirant of this field will face interview questions on blockchain one way or another. Here is the list of questions on blockchain that one should be aware of.
How are transactions and blocks encrypted in the Bitcoin implementation?
Bitcoin blocks are not encrypted in any way: Every block is public. What prevents modifications and guarantees data integrity is a value called the block hash. Block content is processed using a special hash function—in the case of Bitcoin, it’s SHA256—and the resulting value is included in the blockchain.
Explain why a blockchain needs tokens to operate.
Coins/tokens are used to implement changes between states. When somebody does a transaction, this is a change of state, and coins are moved from one address to another. Apart from that, transactions can contain additional data, and a change of state is used to mutate data—the only way to do this is in an immutable-by-definition blockchain. Technically, a blockchain doesn’t need coins for its essential operations, but without them, some other way needs to be introduced to manage states of the chain and to verify transactions.
