問題 #38
Which of the following are likely use cases for blockchain in the energy industry? (Select two.)

A. Energy trading
B. Safety in energy transport
C. Safety in energy production
D. Smart power grids

答案：A,D

解題說明：
Blockchain technology has significant potential in the energy industry, particularly inenergy tradingand smart power grids. By providing a transparent, decentralized, and secure platform for transactions, blockchain can facilitate peer-to-peer energy trading and improve the efficiency and reliability of smart grids.
Key Details:
* Energy Trading: Blockchain enables peer-to-peer energy trading where individuals and companies can buy and sell excess energy (such as solar or wind power) directly to each other. This decentralized model reduces the need for intermediaries and allows consumers to benefit from direct energy sales and purchases.
* Smart Power Grids: Blockchain can enhance smart grid systems by enabling real-time data sharing and automated decision-making. With blockchain, smart grids can securely record and share data related to energy production, consumption, and storage, thereby improving grid management, reducing waste, and optimizing energy distribution.
* Enhanced Transparency and Security: By recording all transactions in an immutable ledger, blockchain ensures transparency and security, reducing the risks of fraud and discrepancies in the energy market. This is especially beneficial in energy trading where trust and accurate record-keeping are essential.
Thus,Energy trading (B)andSmart power grids (D)are the most likely use cases for blockchain in the energy industry.

問題 #39
A____does not result in a new chain and does not require client nodes to upgrade.

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

答案：C

解題說明：
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.

問題 #40
These wallets use a this passphrase to derive the private key

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

答案：A

解題說明：
Brain Walletsderive private keys from a passphrase. This approach allows users to create a wallet by memorizing a unique phrase, which is then hashed to generate the corresponding private key.
Key Details:
* Use of Passphrases: Brain wallets use a passphrase that is entered by the user, typically a string of words that can be remembered easily. This passphrase is then converted into a private key using a cryptographic hash function.
* Security Concerns: While convenient, brain wallets are susceptible to brute-force attacks if the passphrase is not sufficiently complex. Simple or common phrases may be vulnerable to attackers who use lists of common phrases to derive potential private keys.
* Distinction from Deterministic Wallets: Unlike Hierarchical Deterministic Wallets, which use a seed phrase to generate a tree of keys, brain wallets derive a single private key directly from a passphrase.
In conclusion,B. Brain Walletsis the correct answer, as these wallets use a passphrase to generate the private key.

問題 #41
Is a Microsoft blockchain development platform that allows the creation of custom private blockchains.

A. Sratis
B. Corda
C. Fabric
D. Azure

答案：D

解題說明：
MicrosoftAzureis a blockchain development platform that enables the creation of custom private blockchains.
Azure Blockchain Service provides tools and services that allow organizations to set up and manage consortium blockchain networks, customize smart contracts, and create tailored blockchain applications.
Azure supports multiple blockchain frameworks, includingEthereumandHyperledger Fabric, making it versatile for both private and public network needs.
Key Details:
* Azure Blockchain Service: This service facilitates the deployment of managed blockchain networks on the cloud, leveraging Azure's infrastructure to deliver scalability, security, and reliability for private and consortium blockchain applications.
* Private Blockchain Capabilities: As a private blockchain service, Azure allows businesses to operate their blockchain in a controlled, permissioned environment. This offers greater control over data and participants, making it ideal for enterprise use cases like supply chain management, finance, and legal contracts.
* Blockchain Framework Compatibility: Although Azure supports a variety of blockchain protocols, it primarily focuses on private blockchain deployments, allowing for detailed control over network participants and data visibility.
In summary, Microsoft Azure stands out as a flexible and comprehensive platform for private blockchain development, catering to enterprises with tailored solutions and extensive cloud-based services.

問題 #42
The right to publish a new block is determined by ________

A. Transaction history
B. Nod's current investment in the blockchain
C. Position in the blockchain
D. Nodes proof of work

答案：D

解題說明：
The right to publish a new block is commonly determined byProof of Work (PoW)in blockchain networks like Bitcoin. In PoW, network nodes, known as miners, compete to solve a cryptographic puzzle. The first node to successfully solve it gains the right to add a new block to the blockchain.
Key Details:
* Proof of Work Mechanism: Miners perform computational work to solve a hash puzzle, which proves that they have expended effort. This process ensures that blocks are added in a way that is resistant to tampering and fraud.
* Reward System: The miner who successfully publishes a new block receives a block reward (in Bitcoin, for example), incentivizing miners to participate in maintaining the blockchain network's security.
* Alternative Mechanisms: Other consensus mechanisms, such as Proof of Stake (PoS), do not rely on computational work but rather on a node's stake or investment in the blockchain. However, in the context of traditional blockchain models like Bitcoin, PoW is the primary method for determining block publication rights.
Therefore,A. Nodes proof of workis the correct answer, as PoW is the standard method by which nodes earn the right to publish new blocks in many blockchain networks.
