Blockchain with 6G

Why is it necessary to adapt blockchain technology for compatibility with 6G networks?

• To increase the cost of data transmission

• ensure trust, security, and transparency in decentralized networks

• To eliminate the need for decentralization in 6G

• To reduce the speed of 6G communication

What are the key requirements for blockchain in 6G networks?

• Ultra-low latency, high scalability, efficiency, and interoperability

• High latency, energy efficiency, security, and interoperability

• Complex consensus mechanisms and scalability

• Low security, high energy consumption, and centralized control

Which lightweight consensus algorithms are suitable for 6G networks, and why?

• A. Proof of Work (PoW) and Proof of Burn (PoB) because they are secure but slow

• Proof of Authority (PoA) and Delegated Proof of Stake (DPoS) because they are efficient and reduce complexity

• Proof of Stake (PoS) and Proof of Work (PoW) because they require more computational power

• Byzantine Fault Tolerance (BFT) and Proof of Burn (PoB) because they are scalable

What is sharding, and how does it enhance blockchain scalability?

• It combines all network nodes into a single shard to process transactions sequentially.

• It uses complex algorithms to slow down transaction speeds.

• It divides the blockchain network into smaller partitions to process transactions in parallel.

• It eliminates the need for consensus mechanisms in blockchain.

How do DAG-based approaches differ from traditional blockchain structures?

• DAG eliminates transactions entirely in favor of direct communication.

• DAG requires proof of work for transaction validation, while traditional blockchains don’t.

• DAG uses blocks while traditional blockchains use a graph structure.

• DAG organizes transactions in a graph, allowing parallel processing, while traditional blockchains use sequential blocks.
