The blockchain consensus mechanism that selects validators based on staked cryptocurrency is called Proof of ________.
- Decentralized
- Thought
- Stake
- SIDBI / Startup India
Answer: Stake
Proof of Stake selects block validators proportional to staked coins, reducing energy consumption vs Proof of Work. Used by Ethereum, Cardano, Solana. Critical for understanding crypto sustainability.
The CBDC feature that allows transactions without internet connectivity is called ________ Mode.
- Offline
- dimensions
- Healthcare Professionals
- WTO / OECD
Answer: Offline
Offline CBDC uses secure hardware (SE, TEE) to enable limited transactions without network. Critical for rural inclusion, disaster resilience, and areas with poor connectivity. Requires careful security design.
The practice of consolidating multiple servers into fewer physical machines using virtualization is called Server ________.
- Lunar / Space
- Hashing
- Horizontal
