質問 # 28
A____does not result in a new chain and does not require client nodes to upgrade.
- A. Hard fork
- B. Dependent chain
- C. Side 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.

In this method users permanently destroy a certain quantity of bitcoin in proportion to the quantity of altcoin to be demand. What is this method?
- A. Side-chaining
- B. Side block
- C. Proof of Burn
- D. Proof of ownership
正解：C
解説：
Proof of Burn (PoB)is a consensus mechanism where users permanently destroy (or "burn") a certain quantity of cryptocurrency, such as Bitcoin, to gain the right to mine or acquire an altcoin. This process proves commitment to the network and secures it by effectively sacrificing one asset to obtain another.
Key Details:
* Burning Process: In PoB, participants send a certain amount of cryptocurrency to an unspendable address, effectively removing it from circulation. This act serves as proof that they have invested in the network by reducing the supply of the original cryptocurrency.
* Purpose and Use Cases: PoB is used by networks that want to incentivize long-term commitment and reduce total supply. It is often seen in new blockchain projects that allow miners or users to trade value in established currencies like Bitcoin for the native token of the new network.
* Security: By requiring participants to destroy value, PoB helps prevent spam attacks and promotes network stability.
Therefore,B. Proof of Burnis the correct answer, as it describes the method where users destroy a certain amount of cryptocurrency to receive or mine another asset.

When using __________ the chain of ownership is established by a chain of digital signatures as each owner signs when transferring ownership.
- A. NFTS
- B. UTXO
- C. PoET
- D. ETHASH
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.
質問 # 41
Proof of work algorithms are best described as being used for what?
- A. Executing transactions
- B. Proving the user has invested enough in the system
- C. Bitcoin mining
- D. Proof that adequate computational resources have been sent.
正解：D
解説：
Proof of Work (PoW)algorithms are primarily used to demonstrate that sufficient computational resources have been expended by a participant to validate transactions and add them to the blockchain. In PoW, miners compete to solve a cryptographic puzzle, which requires significant computational power. This effort helps secure the network by making it prohibitively expensive for any individual or group to alter the blockchain's history.
Key Details:
* Mechanism of PoW: The essence of PoW is to prove that a certain amount of computational work has been performed. This "work" is measured by the effort miners invest in solving the cryptographic puzzle. The process requires miners to find a nonce that, when hashed with the block's data, results in a hash that meets the network's difficulty requirements.
* Security and Integrity: By proving computational work, PoW ensures that miners cannot simply fabricate or alter transactions without a significant investment of resources. This mechanism deters attacks and makes blockchain networks resistant to tampering and double-spending.
* Association with Bitcoin Mining: Although PoW is often associated with Bitcoin mining (as miners expend computational resources to validate and record transactions), its broader purpose is to establish a cost for participation in the network, ensuring that all entries to the blockchain are trustworthy and secure.
Therefore, PoW is best described as a mechanism for proving that adequate computational resources have been expended, aligning with the correct answer B.
質問 # 42
Who first proposed blind signatures to build an untraceable digital currency?
- A. Wei Dai
- B. David Chaum
- C. Satoshi Nakamoto
- D. Nick Szabo
正解：B
解説：
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.
質問 # 43
A________in a new chain and requires clients to upgrade in order to participate on the new blockchain.
- A. Sharding
- B. Sub chain
- C. Soft fork
- D. Hard fork
正解：D
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 # 44
________can support up to 10-14 transactions per second.
- A. Bitcoin
- B. Ethereum
- C. Dapps
- D. Zcash
正解：B
解説：
Ethereumcurrently supports a transaction throughput of approximately10-14 transactions per second (TPS)
. This transaction speed is a result of Ethereum's design, which balances decentralization and security, albeit at the cost of scalability. This TPS rate is consistent across the Ethereum network prior to its upgrade to Ethereum 2.0, which aims to increase scalability through sharding and Proof of Stake.
Key Details:
* Limitations of Current Throughput: Ethereum's TPS rate is due to limitations in its consensus mechanism (formerly Proof of Work, now Proof of Stake) and block size, which prioritize security over transaction speed.
* Comparison with Other Networks: Bitcoin, for example, supports around 3-7 TPS, while other networks like Solana or Binance Smart Chain support significantly higher TPS. Ethereum's TPS may increase as Ethereum 2.0 is fully implemented, which aims to improve its scalability.
* Impact on Decentralized Applications (DApps): Ethereum's transaction capacity impacts DApps running on the network, as higher usage can lead to congestion and increased transaction fees(gas fees).
The upcoming upgrades are intended to alleviate these issues and enhance performance.
Therefore,D. Ethereumis the correct answer, as it supports approximately 10-14 TPS in its current form.
