質問 # 25
__________ is the process of converting rights to an asset into a digital representation on a blockchain.

A. Cryptomining
B. Proof of Stake
C. Proof of Work
D. Tekenization

正解：D

解説：
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.

質問 # 26
What is a DEX

A. A Decentralized finance app or DApp
B. A cryptocurrency exchange such as coinbase
C. A decentralized exchanged that allows users to exchange cryptocurrency directly
D. A distributed exchange that covers multiple nationalities

正解：C

解説：
ADecentralized Exchange (DEX)is a platform that allows users to trade cryptocurrencies directly with one another without the need for a central intermediary or custodian. On a DEX, trades are facilitated using smart contracts on a blockchain, which automate transactions and ensure transparency. This decentralized model allows for peer-to-peer trading, often providing users with greater privacy and control over their funds compared to centralized exchanges.
Key Details:
* Functionality of DEXs: DEXs enable users to connect their wallets and trade assets directly from their accounts. There is no central authority controlling the funds, reducing the risk of hacks and giving users full control over their private keys.
* Examples of DEXs: Popular DEXs include Uniswap, SushiSwap, and PancakeSwap, which are commonly built on blockchain networks like Ethereum and Binance Smart Chain. These platforms operate through automated market makers (AMMs) or order book systems, which facilitate trading without centralized management.
* Comparison with Centralized Exchanges (CEXs): Unlike centralized exchanges, which act as intermediaries and hold user funds, DEXs do not hold custody of funds. This reduces the risk of theft and enables users to trade directly from their wallets.
Therefore, the correct answer isC. A decentralized exchange that allows users to exchange cryptocurrency directly.

質問 # 27
According to a study be Deloitte, which of the following are benefits of blockchain for the insurance industry (pick two)?

A. Supporting strategic initiatives
B. More efficient claims processing
C. Lower costs
D. Comprehensive interoperable health records

正解：B、C

解説：
According to studies conducted by Deloitte and other industry research, blockchain offers several benefits for the insurance industry, particularly inmore efficient claims processingandlower 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.

質問 # 28
When using __________ the chain of ownership is established by a chain of digital signatures as each owner signs when transferring ownership.

A. ETHASH
B. NFTS
C. UTXO
D. PoET

正解：C

解説：
The UTXO (Unspent Transaction Output) model establishes a chain of ownership by using digital signatures.
In this model, each transaction consists of inputs (from previous UTXOs) and outputs (new UTXOs), and ownership is transferred by the current owner signing the transaction. This digital signature is then verified by the recipient, ensuring a secure and traceable chain of ownership.
Key Details:
Functionality of UTXO: UTXO is a fundamental part of Bitcoin's transaction model. When a transaction occurs, it consumes previous outputs as inputs, generating new UTXOs. Each UTXO can only be spent once, and ownership is verified through cryptographic signatures.
Chain of Ownership: The UTXO model inherently creates a clear and verifiable chain of ownership, as each output is signed by the current owner and used as input for future transactions, maintaining a continuous and transparent record of asset transfers.
Security through Digital Signatures: UTXO-based transactions rely on digital signatures to authenticate and authorize asset transfers, ensuring that only the rightful owner can initiate a transaction.
Thus, D. UTXO is the correct answer, as it accurately describes the model where ownership is established through a chain of digital signatures.

質問 # 29
These wallets store keys in a tree structure derived from a seed.

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

正解：D

解説：
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.
