About the workshop
Research for secure and scalable decentralised systems
Blockchain and distributed ledger technologies can support trustworthy coordination without a central authority. Their use now extends beyond digital currencies into the Internet of Things, cyber-physical systems, healthcare, logistics, e-government, finance and next-generation networks.
These applications also expose difficult research problems. Security weaknesses can affect consensus, smart contracts, wallets, identity systems and cross-chain services. Scalability constraints can limit throughput, latency, storage efficiency and energy use. BSS 2026 provides a focused forum for rigorous methods, practical systems, measurements, attacks, defences and lessons from deployment.
The workshop also examines the growing convergence of blockchain with Agentic AI, large language models and trustworthy AI. It welcomes research on verifiable agent actions, secure coordination between autonomous agents, provenance for AI-generated decisions, decentralised trust and accountability for AI-enabled services.
Zero Trust principles offer another important direction. BSS 2026 encourages work on continuous verification, decentralised identity, policy enforcement, least-privilege access and blockchain-backed auditability across distributed and AI-enabled systems.
The workshop welcomes contributions from academia, industry and government. It values work that clearly states its threat model, evaluation assumptions, limitations and practical implications.
Topics of interest
The scope covers theoretical, experimental and applied research across blockchain security and scalability. Other topics related to security, privacy, trustworthy systems and emerging cyber security challenges are also welcome.
Consensus and fault tolerance
Consensus protocols, Byzantine resilience, incentive design and decentralisation trade-offs.
Scalability and performance
Throughput, latency, storage, sharding, rollups, layer-two systems and performance optimisation.
Smart contracts
Secure design, verification, testing, auditing, chain code and contract-driven applications.
Cross-chain systems
Bridges, interoperability, off-chain methods, modular architectures and composability.
Emerging applications
Blockchain for AI, IoT, edge computing, supply chains, healthcare, e-government and Industry 4.0.
Agentic AI and Blockchain
Secure autonomous agents, verifiable actions, decentralised coordination, provenance and accountability.
Blockchain and LLMs
LLM security, prompt and response provenance, decentralised validation, access control and auditability.
Trustworthy AI
Assurance, transparency, explainability, governance, privacy and verifiable evidence for AI-enabled systems.
Zero Trust and Blockchain
Continuous verification, least-privilege access, decentralised identity, policy enforcement and tamper-evident auditing.
