Dumbo-NG is a novel asynchronous BFT consensus protocol designed for high-performance distributed ledgers, which addresses the trade-off between throughput and latency by enabling concurrent execution of transaction dissemination and agreement. It is notably faster than previous protocols and more resistant to censorship, maintaining low latency even as throughput increases.

4. *FLP impossibility:
No deterministic consensus exists in the asynchronous

5. *N-2f: Redundant Tx.

6. Censorship is a threat:
Occurs when malicious nodes intentionally delay, discard, or selectively block transactions to disrupt the system
