NEW QUESTION # 43
These wallets contain randomly generated private keys and are also called just a bunch of key wallets.

A. Deterministic Wallets
B. Brain Wallets
C. Hierarchical Deterministic Wallets
D. Non-Deterministic Wallets

Answer: D

Explanation:
Non-Deterministic Wallets, also known as"Just a Bunch of Keys" (JBOK)wallets, contain randomly generated private keys that are not derived from a single seed. In this type of wallet, each key is created independently and must be backed up individually, as there is no way to recover keys through a mnemonic seed phrase.
Key Details:
* Random Key Generation: Non-Deterministic wallets generate private keys independently, without a hierarchical or sequential structure. As a result, each key is standalone, and losing a key means losing access to the corresponding funds permanently.
* Backup Requirements: Since each key is unique and unrelated, Non-Deterministic wallets require separate backups for each key. This differs from Hierarchical Deterministic wallets, which can be restored using a single seed phrase.
* Use Case: These wallets were more common in the early days of copyright, but they are less favored today due to the convenience and recoverability provided by deterministic wallets.
In conclusion,C. Non-Deterministic Walletsis the correct answer, as it refers to wallets that contain randomly generated private keys and are known as JBOK wallets.

NEW QUESTION # 44
________is used to split up the tasks into multiple chunks that are then processed by multiple nodes.

A. Parsing
B. Fragmenting
C. Partitioning
D. Sharding

Answer: D

Explanation:
Shardingis a scalability technique that splits tasks or data into smaller, more manageable pieces called
"shards." These shards are then processed in parallel by multiple nodes in a network. By dividing the workload, sharding can significantly enhance the efficiency and speed of blockchain networks, which is especially beneficial for handling large transaction volumes and complex computations.
Key Details:
* Purpose of Sharding: The main goal of sharding is to address blockchain scalability issues. By enabling the network to process transactions and data in parallel, it reduces the load on individual nodes, thus increasing the overall throughput of the blockchain.
* How Sharding Works: In a sharded blockchain, each node only needs to process a portion of the total data rather than every single transaction on the network. Each shard is responsible for a subset of data and transactions, and only nodes within a particular shard need to validate its transactions.
* Relevance in Blockchain: Sharding is crucial in large-scale blockchain networks like Ethereum, where high transaction volumes can lead to congestion. Ethereum 2.0, for example, incorporates sharding as a core feature to improve its scalability and transaction processing capacity.
Sharding is, therefore, the correct answer, as it directly refers to the method of dividing tasks for parallel processing in a distributed environment.

NEW QUESTION # 45
A____does not result in a new chain and does not require client nodes to upgrade.

A. Dependent chain
B. Soft fork
C. Hard fork
D. Side chain

Answer: B

Explanation:
Asoft forkis a change to a blockchain protocol that is backward-compatible, meaning it does not result in the creation of a new chain and does not require all client nodes to upgrade. Nodes that do not upgrade can still participate in the network, although they may not have access to all new features introduced by the soft fork.
Key Details:
* Backward Compatibility: In a soft fork, updated nodes enforce the new rules, while non-updated nodes continue to follow the older protocol but remain part of the same blockchain. This contrasts with hard forks, where incompatibility leads to the creation of a new chain.
* Use Cases: Soft forks are commonly used to implement protocol upgrades or adjustments that do not fundamentally alter the structure of the blockchain, such as increasing block size limits or adding new features that are optional.
* Examples: An example of a soft fork is the Segregated Witness (SegWit) update on the Bitcoin blockchain, which was implemented to increase block capacity without splitting the chain.
Thus,B. Soft forkis the correct answer, as it refers to a backward-compatible update that does not require a new chain or mandatory upgrades from all nodes.

NEW QUESTION # 46
What is the primary way blockchain could help in the food industry?

A. Making transaction ore transparent
B. Eliminating food born illness
C. Making transport safer
D. Streamlining management

Answer: A

Explanation:
Blockchain can greatly benefit the food industry bymaking transactions more transparent. By recording each transaction in an immutable ledger, blockchain enables traceability, which is crucial for food safety, quality control, and ensuring that products meet regulatory standards.
Key Details:
* Traceability: Blockchain allows for the tracking of food products from farm to table. Each step in the supply chain can be recorded on the blockchain, providing consumers and regulators with transparent information about the origin and journey of food products.
* Improving Trust and Safety: With transparent transactions, stakeholders can quickly identify and address issues such as contamination, fraud, or mislabeling, which enhances food safety and consumer trust.
* Enhanced Efficiency: By reducing paperwork and enabling digital record-keeping, blockchain streamlines the process of verifying and sharing information about food products across various parties.
Thus,C. Making transactions more transparentis the correct answer, as it highlights blockchain's role in providing transparency in the food industry.

NEW QUESTION # 47
Public blockchains most often use________ as a consensus mechanism.

A. PoS
B. PoET
C. PoB
D. PoW

Answer: D

Explanation:
Public blockchains most commonly useProof of Work (PoW)as their consensus mechanism, especially in well-established networks such as Bitcoin and, until recently, Ethereum. PoW is a protocol that relies on network participants (miners) solving complex mathematical problems to validate and add transactions to the blockchain. This process ensures the integrity and security of the network, as it requires substantial computational power and resources, making it difficult for any single entity to control the blockchain.
Key Details:
* Proof of Work (PoW): PoW, used primarily by Bitcoin, operates by having participants (often referred to as miners) compete to solve cryptographic puzzles. The first to solve the puzzle adds the next block of transactions to the blockchain and is rewarded with newly minted coins. This system is energy- intensive but is widely recognized for its security and resistance to tampering.
* Transition in Other Networks: While Ethereum initially used PoW, it transitioned toProof of Stake (PoS)in 2022 with Ethereum 2.0, due to PoS's lower energy requirements and increased scalability.
However, Bitcoin, the most prominent public blockchain, still relies on PoW.
* Other Consensus Mechanisms: Alternatives such asProof of Stake (PoS)andProof of Burn (PoB)are used by other blockchain networks that aim for different trade-offs in terms of energy efficiency, scalability, and security.Proof of Elapsed Time (PoET)is another mechanism mostly associated with permissioned (private) blockchains rather than public blockchains.
* Why PoW for Public Blockchains?: Public blockchains prioritize decentralization and security. PoW provides a robust way to achieve this, despite its high energy consumption. Its high level of security and historical success in Bitcoin's network often make it the go-to choice for public blockchains.
In summary, the dominance of PoW in public blockchains is due to its established security and proven track record, although PoS and other mechanisms are increasingly gaining popularity for their efficiency in newer blockchain projects.
