質問 # 28
A____does not result in a new chain and does not require client nodes to upgrade.
- A. Hard fork
- B. Side chain
- C. Dependent chain
- D. Soft fork
正解：D
解説：
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.
質問 # 29
Public blockchains most often use________ as a consensus mechanism.
- A. PoW
- B. PoET
- C. PoB
- D. PoS
正解：A
解説：
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.

質問 # 31
When using __________ the chain of ownership is established by a chain of digital signatures as each owner signs when transferring ownership.
- A. PoET
- B. UTXO
- C. ETHASH
- D. NFTS
正解：B
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.

- B. A decentralized exchanged that allows users to exchange cryptocurrency directly
- C. A distributed exchange that covers multiple nationalities
- D. A Decentralized finance app or DApp
正解：B
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.

正解：C、D
解説：
In Ethereum, there are two main types of transactions:Message CallandContract Creation. These transaction types enable Ethereum to support both the execution of contracts and interactions between accounts.
Key Details:
* Message Call Transactions: These transactions involve interactions between externally owned accounts (EOAs) or between EOAs and smart contracts. Message calls are used to transfer Ether or invoke functions within existing smart contracts.
* Contract Creation Transactions: This transaction type is used specifically to deploy new smart contracts on the Ethereum blockchain. During a contract creation transaction, the code for the new contract is included, which the network processes and stores at a unique address.
* Exclusion of User Transactions: While "User" refers to EOAs, it is not a type of transaction itself in Ethereum. Transactions in Ethereum are categorized based on their purpose - either calling an existing contract (Message Call) or creating a new one (Contract Creation).
Thus,C. Message CallandD. Contract Creationare the correct answers, as they represent the two main transaction types in Ethereum.
質問 # 38
A________in a new chain and requires clients to upgrade in order to participate on the new blockchain.
- A. Sub chain
- B. Soft fork
- C. Hard fork
- D. Sharding
正解：C
解説：
Ahard forkoccurs when there is a fundamental change in a blockchain's protocol, resulting in the creation of a new chain that is incompatible with the previous one. After a hard fork, nodes must upgrade to the new version of the blockchain's software to continue participating in the network. A hard fork can be used to implement new features, fix security issues, or change core aspects of the blockchain.
Key Details:
* Differences from Soft Forks: Unlike a soft fork, which is backward-compatible and allows nodes on the previous version to still participate, a hard fork splits the blockchain into two distinct paths, with the upgraded path requiring new software.
* Examples: Notable hard forks include Bitcoin Cash from Bitcoin and Ethereum Classic from Ethereum. These forks occurred due to disagreements within the community on how to handle certain protocol changes, leading to the creation of separate blockchains.
* Upgrade Requirements: Participants on the blockchain who wish to continue on the new chain after a hard fork must update their software. Those who do not upgrade remain on the original chain, which continues as a separate, incompatible blockchain.
Thus, the correct answer isHard fork (A), as it directly refers to a blockchain split that requires client upgrades for participation.
質問 # 39

_______uses a Trusted Execution environment (TEE) to provide randomness and safety in the leader election process via a guaranteed wait time.
- A. PoD
- B. Pol
- C. PoET
- D. PoA
正解：C
解説：
Proof of Elapsed Time (PoET)is a consensus mechanism that uses a Trusted Execution Environment (TEE) to ensure randomness and safety in the leader election process by enforcing a guaranteed wait time.
Developed by Intel, PoET is particularly used in permissioned blockchain networks where a TEE can securely run code to determine which node is elected to propose the next block. This mechanism is efficient in terms of energy consumption and provides a fair method for selecting a leader without requiring intensive computational power.
Key Details:
* Role of TEE in PoET: The TEE ensures that nodes wait for a random period before being eligible to propose a new block. This waiting period is verified by the TEE, which acts as a trusted third party to confirm that nodes have adhered to the assigned wait time.
* Randomness and Security: PoET provides randomness in the leader selection process, reducing the chances of any node gaining an unfair advantage. It also promotes security by leveraging the TEE, which is designed to prevent tampering with the waiting time calculations.
* Use Cases: PoET is mainly used in permissioned blockchain environments like Hyperledger Sawtooth, where nodes are pre-approved, and there is a need for a scalable yet secure consensus mechanism.
In summary, PoET is the correct answer as it directly refers to a consensus mechanism that utilizes a Trusted Execution Environment for leader election.

________is used to split up the tasks into multiple chunks that are then processed by multiple nodes.
- A. Sharding
- B. Parsing
- C. Partitioning
- D. Fragmenting
正解：A
解説：
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.
