The financial Action Task force defines virtual asset providers as companies that (choose two):

  1. Sell products for virtual currency
  2. Purchase virtual currency
  3. Exchange virtual assets for fiat currency
  4. Transfer virtual assets

Answer(s): C,D

Explanation:

The Financial Action Task Force (FATF) defines Virtual Asset Service Providers (VASPs) in its guidelines to include entities that engage in the exchange of virtual assets for fiat currency and the transfer of virtual assets. This categorization is part of the FATF's efforts to regulate and monitor the flow of virtual assets to mitigate risks associated with illicit activities.
Key Details:
Exchange and Conversion Services: FATF recognizes companies that offer exchange services between virtual assets and fiat currencies as VASPs. These services are critical for converting virtual assets into forms that can be readily used in traditional markets. Transfer Services: VASPs that facilitate the transfer of virtual assets are also within the FATF's regulatory scope. This includes services that manage, transfer, or act as intermediaries in the movement of virtual assets between users, ensuring these transactions are conducted transparently and within regulatory frameworks.
Therefore, C. Exchange virtual assets for fiat currency and D. Transfer virtual assets are the correct answers, as they align with the FATF's definition of VASPs.



A________represents a transfer of value from one address to another, Transaction in a blockchain network can be defined also as a record of an event or the `'transfer of value from one account to another''

  1. Hash function
  2. Block
  3. Signature
  4. transaction

Answer(s): D

Explanation:

In blockchain terminology, a transaction represents the transfer of value from one address to another. Each transaction is recorded on the blockchain as an immutable entry, often representing a movement of digital assets or a record of an event.
Key Details:
Nature of Transactions: A blockchain transaction involves a digital asset or token being sent from one blockchain address (wallet) to another. The transaction is broadcast to the network, validated by nodes, and then recorded on the blockchain ledger.
Transfer of Value: Blockchain transactions serve as proof of the transfer of value, which could represent cryptocurrency movement, digital asset exchange, or a specific record of an event,
depending on the blockchain's purpose.
Inclusion in Blocks: Each transaction is grouped into blocks, which are then cryptographically linked together, forming the blockchain. This ensures all transactions are secure, traceable, and verifiable. Thus, D. Transaction is the correct answer, as it describes the fundamental concept of transferring value on a blockchain.



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

  1. NFTS
  2. ETHASH
  3. PoET
  4. UTXO

Answer(s): D

Explanation:

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.



These wallets contain randomly generated private keys and are also called just a bunch of key wallets.

  1. Brain Wallets
  2. Hierarchical Deterministic Wallets
  3. Non-Deterministic Wallets
  4. Deterministic Wallets

Answer(s): C

Explanation:

Non-Deterministic Wallets, also known as "Just a Bunch of Keys" (JBOK) wallets, contain randomly generated private keys that are not derived from a single seed. In this type of wallet, each key is created independently and must be backed up individually, as there is no way to recover keys through a mnemonic seed phrase.
Key Details:

Random Key Generation: Non-Deterministic wallets generate private keys independently, without a hierarchical or sequential structure. As a result, each key is standalone, and losing a key means losing access to the corresponding funds permanently.
Backup Requirements: Since each key is unique and unrelated, Non-Deterministic wallets require separate backups for each key. This differs from Hierarchical Deterministic wallets, which can be restored using a single seed phrase.
Use Case: These wallets were more common in the early days of cryptocurrency, but they are less favored today due to the convenience and recoverability provided by deterministic wallets. In conclusion, C. Non-Deterministic Wallets is the correct answer, as it refers to wallets that contain randomly generated private keys and are known as JBOK wallets.
