Q1Domain Verified
In the context of securing IoT devices using blockchain, which consensus mechanism is generally considered the most suitable for a highly distributed and resource-constrained IoT network, balancing security and energy efficiency?
Proof-of-Stake (PoS)
Delegated Proof-of-Stake (DPoS)
Practical Byzantine Fault Tolerance (PBFT)
Proof-of-Work (PoW)
Q2Domain Verified
When implementing a blockchain for IoT device identity management, what is the primary benefit of using a decentralized identifier (DID) anchored on a blockchain compared to a centralized identity provider?
Simplified integration with existing cloud-based IoT platforms.
Reduced data storage requirements on individual IoT devices.
Faster initial device registration and provisioning.
Enhanced immutability and tamper-proofing of device credentials and attestations.
Q3Domain Verified
Consider an IoT network where devices need to securely exchange sensitive data with minimal latency. Which blockchain architecture would be most appropriate to address these requirements, considering both performance and security?
A private, permissioned blockchain with a high-throughput consensus mechanism.
A public, permissionless blockchain like Ethereum.
A sidechain or layer-2 solution integrated with a public blockchain.
A consortium blockchain with frequent block creation.
