Episode 155: Testing PoW Consensus Algorithm Security with Ren Zhang from Nervos

In this week’s episode, we revisit the topic of consensus algorithms with Ren Zhang, a researchers at Nervos and previously at imec-COSIC (KU Leuven). We chat about an earlier work he did on evaluating PoW consensus protocols security and explore his more recent work on NC-Max – a consensus protocol that breaks the throughput limit and enables the full utilization of the nodes’ bandwidth in confirming transactions

Here are a few of the links we mention in the interview:
