HerMES is introduced, a novel dissemination protocol for mempools that leverages robust minimal structures to optimize data propagation, balance load, and ensure fairness despite faults and Byzantine actors that addresses front-running attacks.

Hopper, a bounded-memory debiasing protocol for Byzantine-tolerant peer sampling is introduced and the importance of occurence freshness is shown as a key requirement for practical frequency-aware Byzantine peer sampling.

AUPE is introduced, the first collaborative Byzantine-tolerant peer sampling protocol that leverages the presence of trusted nodes, such as Intel’s SGX capable devices, to collaboratively track the spread of identifiers in the system and locally debias the representation of Byzantine nodes.
