NEW QUESTION # 38
_______uses a Trusted Execution environment (TEE) to provide randomness and safety in the leader election process via a guaranteed wait time.

  • A. PoA
  • B. Pol
  • C. PoD
  • D. PoET

Answer: D

Explanation:
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.


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

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

Answer: B

Explanation:
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.


NEW QUESTION # 40
Self-executing computer programs which facilitate transaction automation and eliminates the need for intermediaries are called what?

  • A. Smart contracts
  • B. Bitcoin mining
  • C. Cryptocurrencies
  • D. Distributed ledgers

Answer: A

Explanation:
Smart Contractsare self-executing computer programs that automatically enforce, verify, and facilitate the terms of a contract when certain conditions are met. These programs run on blockchain networks and eliminate the need for intermediaries by automating transactions based on predefined rules coded into the contract.
Key Details:
* Automation and Trust: Smart contracts are crucial in blockchain technology because they enable trustless transactions, meaning parties can transact directly without relying on intermediaries. The code controls the execution, and transactions are transparent and irreversible.
* Use Cases: Smart contracts are foundational to decentralized finance (DeFi) applications, supply chain management, digital identity, and more. They facilitate various operations such as lending, borrowing, insurance, and automated asset transfers.
* Example in Ethereum: Ethereum popularized smart contracts by providing a platform with Turing- complete scripting capabilities. This allowed developers to create sophisticated decentralized applications that execute on the blockchain.
In conclusion,D. Smart contractsis the correct answer as it refers to the technology that automates transactions and eliminates the need for intermediaries.


NEW QUESTION # 41

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.


NEW QUESTION # 42
__________ is the process of converting rights to an asset into a digital representation on a blockchain.

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

Answer: C

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.
