commitbrief.comHardening Kademlia DHT: Signing Alone Won't Stop Eclipse
A signed-record fix in py-libp2p blocks forged PeerRecords, but Kademlia routing stays exposed to Sybil/Eclipse attacks; S/Kademlia's disjoint lookup paths offer a practical fix.
Testing Distributed Systems with AI Coding Agents
Two SKILL.md based agent skills generate claim-driven test plans and verdict reports for distributed systems, working with Claude Code, Codex, and more.
Deployment Status Is Actually a Distributed Systems Problem
Drawing on Guara Cloud's build experience, this piece explains why 'pending' labels fail and how deployment status must be modeled as evidence-based distributed state.
Rings rebuilds distributed system correctness with algebraic structures
Rings unifies cryptography, CRDT-based storage and Chord topology under group, ring and module algebra, aiming for a provably correct distributed system.
LLM agents are breaking 20-year-old web architecture
Stateful LLM agents are exposing cracks in the stateless-server-plus-database web architecture. The missing piece: a routing primitive that can address running processes directly.
Grudge: A Decaying Score Sketch for Multi-Tenant Systems
Grudge is a constant-memory Go library that decays per-key feedback scores without per-key state, enabling scalable rate limiting and abuse detection.
How to Make an AI Agent's History Truly Unforgeable
An AI agent's unforgeable-history claim failed audit: dual writers, race conditions, corrupted records. Fix: single writer, signed anchor, fail-closed design.
