ACM CoNEXTWorkshop on Blockchain-Network Synergy: Addressing Network-Centric Challenges in Decentralized Systems (BlockNetSys 2025)
Co-located with ACM CoNEXT 2025, Hong Kong, China. December 1st, 2025.
Statement of Interest
As the Internet continues to evolve toward hyper-distributed, even decentralized, and trustless infrastructure, blockchain technologies are emerging as a foundational component to enable secure, verifiable, and autonomous interactions between decentralized systems. Meanwhile, the decentralization revolution faces a critical bottleneck: network-layer limitations. While blockchain promises trustless coordination, its practical deployment is constrained by fundamental networking challenges:
The latency-throughput paradox: Blockchain’s security relies on global state synchronization, yet network propagation delays inherently limit transaction throughput (e.g., Bitcoin’s 7TPS vs. Visa’s 24,000TPS).
Topology-awareness gap: Current P2P overlays operate agnostically to physical network topology, causing inefficient broadcast storms and unnecessary cross-continental traffic.
Consensus-network mismatch: BFT protocols like PBFT assume synchronous networks, while real-world deployments face asymmetric latencies and intermittent connectivity.
Verifiability-cost tradeoff: Zero-knowledge proofs enable privacy but generate 10- 100x more network payload (IEEE S&P’23 measurements)
BlockNetSys will pioneer network-aware blockchain design by:
Developing network-optimized consensus protocols leveraging programmable data planes;
Redesigning topology-sensitive P2P overlays using network coordinates;
Creating hybrid trust models that balance decentralization with network realities.
The Aim of this Workshop
We seek to bring together researchers from networking, distributed systems, and blockchain communities to discuss opportunities and challenges in addressing the network-centric challenges in blockchains and decentralized systems.
This workshop is particularly relevant to the CoNEXT community, where emphasis on systems design, real-world deployments, and forward-looking architecture aligns closely with the emerging vision of decentralized intelligent network infrastructure.
We invite original papers (4–6 pages) that address network-layer challenges in blockchain systems and networks. We also explore the blockchain-empowered architecture, systems, and protocols for networking, decentralized systems, and trusted infrastructures.
Topics of interest
Topics of interest include, but are not limited to:
Trust-aware data routing and verifiable network telemetry
Token-based incentive mechanisms for network resource sharing
Decentralized identity, naming, and access control for network services
Smart contract-based networking and systems
Blockchain-assisted federated learning and decentralized machine learning
Zero-knowledge proofs and cryptographic systems for privacy-preserving networking
Blockchains and software engineering for edge-cloud networking
Lightweight blockchain systems for embedded and IoT networks
Consensus protocols tailored for distributed networks
Cross-chain technologies for distributed Networks and Systems
SpecialEmphasis: We particularly encourage:
Measurement studies of blockchain network traffic
Network stack modifications for blockchain workloads
Hardware/software co-designs that reduce networking overhead
