Cloudflare chooses leaderless QuePaxa for its Meerkat control plane
A 2020 partial switch failure left a leader-based Cloudflare system unable to take writes and about 80 times slower for six hours.
AI agents discover A-greement, a faster geo-replicated consensus protocol
Across six 5- or 9-replica deployments, mean latency fell 12.2% on write-heavy and 33.3% on read-heavy workloads.
Distributed Performance Boosting through Neural Control for Plug-and-Play Networks
Unconstrained neural controllers improve plug-and-play network performance while preserving a guaranteed gain bound.
From Mixing to Tearing: Graph Decomposition in Decentralized Optimization via Message Passing
GATE introduces a graph-tearing message passing framework that jointly designs subproblems and communication for decentralized optimization over agent clusters.
Steelhead: Interleaving Partially Synchronous and Asynchronous Commit Rules on a Shared DAG
Steelhead interleaves partially synchronous and asynchronous DAG commit rules and adapts without extra messages.
Hydrozoan: Latency-Adaptive DAG Consensus under Mixed Byzantine and Crash Faults
Hydrozoan is a DAG consensus protocol that commits in two or three delays under mixed Byzantine and crash faults.
Hopper: Bounded-Memory Collaborative Debiasing for Byzantine-Tolerant Peer Sampling
Researchers propose Hopper, a bounded-memory debiasing protocol that protects Byzantine-tolerant peer sampling from delayed balanced attacks defeating cumulative counters.
RayOrch: Programming and Executing Lineage-Controlled Multi-Grain Dataflows for Foundation-Model Data Preparation
RayOrch keeps parent-child lineage in foundation-model data pipelines and speeds MinerU up to 15.14× on 64 GPUs.
You've Got a BUD in Me: Authenticated Reads from Per-Block Write Logs
Researchers propose BUD, per-block write-log digests enabling blockchain validators to serve historical membership and exclusion proofs far cheaper than state-wide tries.
Distributed and Private Textual Data Synthesis from Embeddings
Researchers propose a distributed differentially private text synthesis method combining DP summaries and secure protocols, removing the need for a trusted curator.
Scalable Composition of Byzantine Agreements under Reorder Attacks
Researchers present the first adversary model combining party corruption with channel reordering attacks, establishing tight security thresholds for composed Byzantine agreement protocols.
