NEW QUESTION # 23
These wallets store keys in a tree structure derived from a seed.
- A. Brain Wallets
- B. Deterministic Wallets
- C. Hierarchical Deterministic Wallets
- D. Non-Deterministic Wallets
Answer: C
Explanation:
Hierarchical Deterministic (HD) Walletsare wallets that generate private and public keys in a tree structure, starting from a single seed phrase. This seed phrase can generate multiple key pairs, allowing users to back up and recover all their wallet addresses using one phrase, which enhances security and convenience.
Key Details:
* Tree Structure: HD wallets use a root seed to derive an entire hierarchy of keys. Each branch in the tree can create new sub-branches, generating separate addresses for different transactions without reusing them, which provides better privacy.
* Seed-Based Recovery: Users can restore all wallet addresses with the original seed phrase, making HD wallets more secure and easy to back up compared to non-deterministic wallets, which would require individual backups for each key.
* Compatibility with Blockchain Standards: HD wallets adhere to the BIP32 and BIP44 standards, which outline the derivation paths and formats used by these wallets. This compatibility allows for interoperability among different wallet providers.
In conclusion, Hierarchical Deterministic Wallets (answer B) best describes wallets that store keys in a tree structure derived from a seed.
NEW QUESTION # 24
A________ is a blockchain where participants of the network are already known and trusted.
- A. Smart contract
- B. Hyperledger Fabric
- C. Permissioned ledger
- D. Permission less ledger
Answer: C
Explanation:
APermissioned ledgeris a blockchain where participants are known and trusted, and access to the network is restricted to authorized entities. Permissioned ledgers are commonly used in enterprise and consortium settings where privacy, compliance, and control over data are essential.
Key Details:
* Controlled Access: In a permissioned ledger, only pre-approved participants can validate transactions and participate in the consensus process. This model ensures that all network members are identified and trusted, which is ideal for environments requiring a higher level of control and privacy.
* Use Cases: Permissioned ledgers are widely used in industries such as finance, healthcare, and supply chain, where it's important to know and trust participants due to regulatory or operational needs.
* Contrast with Permissionless Ledgers: Unlike permissionless ledgers (such as Bitcoin), which allow anyone to join and participate in the network, permissioned ledgers restrict participation to entities that meet specific criteria.
Thus,A. Permissioned ledgeris the correct answer, as it describes a blockchain network where participants are known and trusted.
NEW QUESTION # 25
According to a study be Deloitte, which of the following are benefits of blockchain for the insurance industry (pick two)?
- A. More efficient claims processing
- B. Supporting strategic initiatives
- C. Comprehensive interoperable health records
- D. Lower costs

Blockchain's capabilities in data immutability, transparency, and automation play key roles in streamlining insurance processes and reducing operational expenses.
Key Details:
* Efficient Claims Processing: Blockchain enables quicker verification and processing of claims by automating workflows through smart contracts. This reduces paperwork, minimizes errors, and speeds up the claims process, improving customer satisfaction.
* Lower Costs: By reducing intermediaries and leveraging automation, blockchain lowers administrative costs. It minimizes the need for manual verification and fraud detection, which traditionally consume significant resources in the insurance industry.
* Transparency and Fraud Reduction: Blockchain provides an immutable and transparent record of all transactions. This helps prevent fraud, as all stakeholders have access to the same data, reducing discrepancies and the need for extensive audits.
In conclusion,A. More efficient claims processingandD. Lower costsare the correct answers, as these are key benefits of blockchain for the insurance industry identified in Deloitte's research.
NEW QUESTION # 26
Who first proposed blind signatures to build an untraceable digital currency?
- A. Wei Dai
- B. Nick Szabo
- C. David Chaum
- D. Satoshi Nakamoto
Answer: C
Explanation:
David Chaumfirst proposed the concept ofblind signaturesin the early 1980s as a way to create an untraceable digital currency. Chaum's work laid the groundwork for digital privacy in financial transactions by enabling transactions to be signed without revealing the actual content of the transaction, thus maintaining user privacy.
Key Details:
* Blind Signatures: A blind signature is a form of digital signature in which the content of a message is hidden (or "blinded") before being signed. This allows for privacy-preserving digital transactions, as the signer cannot see the actual content they are signing.
* Application in Digital Currency: Chaum's idea was foundational for the development of anonymous electronic cash systems. His work led to the creation of DigiCash in 1989, one of the earliest forms of digital currency focused on user privacy.
* Influence on Modern Cryptocurrencies: Although Chaum's DigiCash was not a blockchain-based system, his concepts of privacy and anonymous transactions greatly influenced the development of later cryptographic currencies and protocols, including Bitcoin.
Therefore,A. David Chaumis the correct answer, as he pioneered the use of blind signatures for anonymous digital currency.
NEW QUESTION # 27
__________ is the process of converting rights to an asset into a digital representation on a blockchain.
- A. Cryptomining
- B. Tekenization
- C. Proof of Stake
- D. Proof of Work
Answer: B
Explanation:
Tokenizationis the process of converting rights to an asset into a digital representation on a blockchain. This process allows assets like real estate, art, or securities to be represented as digital tokens that can be traded or transferred on a blockchain.
Key Details:
* Digital Representation of Assets: Tokenization involves creating digital tokens on a blockchain that represent ownership or rights to a real-world asset. These tokens can be transferred and traded much like traditional assets.
* Advantages of Tokenization: By enabling fractional ownership, tokenization lowers barriers to investment and improves liquidity. It also provides transparency and traceability in asset transactions.
* Use Cases: Tokenization is widely used in real estate, art, and securities, as it facilitates easy transfer, enhances liquidity, and enables global access to traditionally illiquid assets.
Thus,D. Tokenizationis the correct answer, as it describes the process of converting asset rights into a digital form on a blockchain.
