In modern blockchains, efficient, fair, and faulttolerant information dissemination is critical for performance and security. Several stages of the transaction lifecycle are affect…
Hopper: Bounded-Memory Collaborative Debiasing for Byzantine-Tolerant Peer Sampling
Joachim Bruneau-Queyreix, Laurent Reveillère, Augusta Mukam
Byzantine-tolerant peer sampling relies on continuously refreshed views, yet an adversary can bias the identifier streams used to construct them. Frequency-aware debiasing downweig…
Tolerating Disasters with Hierarchical Consensus
Wassim Yahyaoui, Joachim Bruneau-Queyreix, Jérémie Decouchant +1
Geo-replication provides disaster recovery after catastrophic accidental failures or attacks, such as fires, blackouts or denial-of-service attacks to a data center or region. Natu…
RAPTEE: Leveraging trusted execution environments for Byzantine-tolerant peer sampling services
Matthieu Pigaglio, Joachim Bruneau-Queyreix, David Bromberg +3
Peer sampling is a first-class abstraction used in distributed systems for overlay management and information dissemination. The goal of peer sampling is to continuously build and…
ALDER: Unlocking blockchain performance by multiplexing consensus protocols
