### Recipe: Hardware-Accelerated Replication Protocols: Rethinking Crash Fault Tolerance Protocols for Untrusted Cloud Environments

*Dimitra Giantsidi, Emmanouil Giortamis, Julian Pritzi, Maurice Bailleu *et al.**

**TL;DR** — Redesigns crash fault-tolerance protocols using hardware acceleration (TEEs/SmartNICs) to deliver replication with strong guarantees in untrusted cloud environments.

---

### Efficient Performance Guarantees for Function-as-a-Service with Cloud Allocators

*Hai Duc Nguyen 0005, Andrew A. Chien*

**TL;DR** — Introduces cloud-allocator abstractions that provide formal performance guarantees for serverless functions, addressing the unpredictability of shared FaaS infrastructure.

---

### Capybara: an Edge-Friendly Distributed Object Store for Diverse Serverless Functions

*Xin Chen 0084, Manoj Prabhakar Paidiparthy, Chen Qian 0001, Liting Hu*

**TL;DR** — Proposes a distributed object store purpose-built for edge serverless workloads, enabling diverse function runtimes to share state efficiently at the edge.

---

### EdgeConnector: Enabling Seamless and Efficient Cross-Cluster Device Access in Edge Environment

*Yunna Cui, Liwei Shen, Bingkun Sun, Wente Lu *et al.**

**TL;DR** — Presents a middleware layer that transparently bridges device access across Kubernetes clusters in heterogeneous edge deployments.

---

### FaaSImage: An Efficient Image Manager for FaaS

*Abhisek Panda, Smruti R. Sarangi*

**TL;DR** — Tackles cold-start latency in production FaaS platforms by redesigning container image management with fine-grained layer sharing and prefetching.

---

### Roadrunner: Accelerating Data Delivery to WebAssembly-Based Serverless Functions

*Cynthia Marcelino, Thomas W. Pusztai, Stefan Nastic*

**TL;DR** — Designs a high-throughput data-plane runtime that removes I/O bottlenecks for Wasm serverless functions through zero-copy data paths.

---

### Mocha: Scalable and Compliant Function Scheduling for Federated Serverless Computing

*Yuqiu Zhang, Hans-Arno Jacobsen*

**TL;DR** — Introduces a scheduler for federated serverless environments that satisfies data-residency and compliance constraints while maintaining high resource utilization.

---

### A Hybrid Runtime for Function-as-a-Service at the Edge

*Adam Hall, Umakishore Ramachandran*

**TL;DR** — Combines container and unikernel execution models in a single FaaS runtime to balance isolation, startup latency, and resource efficiency at edge nodes.

---

### Tiaccoon: Unified Access Control with Multiple Transports in Container Networks

*Hiroya Onoe, Daisuke Kotani, Yasuo Okabe*

**TL;DR** — Provides a service-mesh-style unified access-control plane that works across heterogeneous transport protocols within container network environments.

---

### MiAR-BFT: Efficient Leaderless Consensus Based on Multi-instance Asynchronous Running for Blockchain

*Zhenyu Zhang, Xing Tong, Zhao Zhang 0009, Cheqing Jin*

**TL;DR** — Proposes a leaderless BFT consensus protocol that runs multiple instances concurrently to improve throughput and reduce latency in blockchain middleware.

---

### ER-π: Exhaustive Interleaving Replay for Testing Replicated Data Library Integration

*Provakar Mondal, Eli Tilevich*

**TL;DR** — Systematically explores all message interleavings when testing replicated data libraries, surfacing integration bugs that random testing misses in distributed coordination code.

---

### Adjusted Objects: An Efficient and Principled Approach to Scalable Programming

*Boubacar Kane, Pierre Sutra*

**TL;DR** — Introduces adjusted objects as a programming abstraction that reconciles strong consistency with scalability, offering a practical alternative to CRDTs for distributed middleware.
