How Agora Uncovered 15 Zero‑Day Deep Bugs in Consensus Protocols with an Industrial‑Grade Multi‑Agent Framework

The paper presents Agora, a hypothesis‑driven multi‑agent system that integrates domain knowledge with large‑model agents to automatically detect deep logic bugs in production‑level consensus protocols, discovering 15 previously unknown vulnerabilities across Raft, EPaxos, HotStuff and BullShark while outperforming GPT‑5.2, Claude 4.5 and other baselines at a fraction of the token cost.

Abase: ByteDance’s Large‑Scale Online KV Storage System – Architecture, High Availability, and Key Technologies

This article introduces Abase, ByteDance’s massive online KV storage system, detailing its evolution from a single‑cluster KV service to a multi‑region, multi‑tenant platform, and explains the high‑availability challenges and the leaderless multi‑write architecture, hybrid logical clocks, quorum settings, and performance optimizations that enable hundred‑billion QPS and sub‑10 ms latency.

Consistency, CAP Theorem, and Distributed Consensus Protocols (2PC, 3PC, Paxos, Raft, Zookeeper)

The article explains how the CAP theorem forces trade‑offs between consistency, availability and partition tolerance, then surveys distributed commit protocols (2PC, 3PC) and consensus algorithms (Paxos, Raft, Zookeeper’s ZAB), and shows their practical use in systems such as ZanKV that combine Raft with RocksDB for strongly consistent, fault‑tolerant key‑value storage.
