Which privacy technique enables selective disclosure of transaction details in CBDC?
- Zero-Knowledge Proofs
- Ring Signatures
- Confidential Transactions
- All of these
Answer: All of these
Privacy-preserving CBDC: ZK-proofs verify without revealing data; ring signatures obscure sender; confidential transactions hide amounts. Balance user privacy with regulatory auditability requirements.
India's crypto tax framework allows deduction of acquisition cost when computing taxable income.
- True
- False
Answer: False
Section 115BBH taxes crypto income at 30% on gross transfer value, no deduction for acquisition cost except cost of acquisition. No loss offset allowed. Critical for accurate crypto tax compliance.
Which CBDC benefit enables faster cross-border payments compared to correspondent banking?
- Direct Central Bank Settlement
- 24/7 Operation
- Reduced Intermediaries
- All of these
Answer: All of these
CBDC cross-border: direct central bank-to-central bank settlement, operates 24/7, reduces correspondent layers. Critical for trade finance efficiency, remittance cost reduction, and financial inclusion.
The distributed ledger technology used in India's CBDC pilot is based on ________ Ledger.
Answer: Permissioned Blockchain / Distributed
e₹ uses permissioned distributed ledger with RBI and partner banks as nodes. Balances decentralization benefits with regulatory control, privacy, and performance requirements. Critical for CBDC architecture understanding.
CBDC can enable programmable welfare payments with usage restrictions to prevent misuse.
- True
- False
Answer: True
Programmable CBDC allows conditional transfers: subsidies usable only for food, education, healthcare. Enhances policy effectiveness while requiring careful design to balance control with user autonomy.
Which Indian provision imposes 1% TDS on cryptocurrency transactions?
- Section 194S
- Section 115BBH
- Section 43A
- Section 66
Answer: Section 194S
Section 194S (Income Tax Act) imposes 1% TDS on transfer of virtual digital assets above threshold. Aims to track transactions and ensure tax compliance. Critical for crypto tax reporting obligations.
