International Workshop on Blockchain Security (BSEC 2025)

Blockchain technology has evolved from supporting cryptocurrency systems to becoming a critical infrastructure for decentralized trust architectures. As adoption expands across financial services, supply chain management, and digital identity systems, the attack surface of blockchain ecosystems grows in both complexity and scale. This workshop addresses the fundamental security challenges arising from this transformation, where the immutable nature of blockchain systems paradoxically amplifies the consequences of security vulnerabilities.

The security challenges facing blockchain systems are undergoing a fundamental evolution as the technology matures and finds broader adoption. This transformation stems from complex interactions between technological advancements, architectural trade-offs, and emerging requirements in real-world deployments. These multidimensional developments are reshaping core security assumptions and creating new research imperatives that span theoretical foundations to practical implementations.

This workshop seeks to address critical questions at the forefront of blockchain security research: How can next-generation blockchain systems achieve provable security without compromising decentralization? What novel cryptographic approaches can simultaneously address quantum threats and regulatory compliance? How should security frameworks evolve to protect complex cross-chain ecosystems? What methodologies can effectively verify the safety of Turing-complete smart contracts?

This workshop invites original research, case studies, and reviews at the intersection of blockchain, AI, large models, and Web 3.0. Key themes include (but are not limited to):

• A. Core Protocol Security

  - Formal verification of blockchain consensus mechanisms (PoW, PoS, BFT, etc.)

  - Cryptographic vulnerabilities in blockchain implementations

  - Resistance to 51% attacks and sybil attacks

  - Post-quantum blockchain cryptography

  - Secure cross-chain communication protocols

• B. Smart Contract Security

  - Automated vulnerability detection in smart contracts

  - Secure development practices for Solidity/Vyper

  - Formal verification frameworks (e.g., KEVM, Certora)

  - Reentrancy, front-running, and gas optimization attacks

  - Decentralized Oracle security

• C. Privacy & Anonymity

  - Zero-knowledge proof systems (zk-SNARKs, zk-STARKs)

  - Secure multi-party computation in blockchain

  - Privacy-preserving transaction protocols

  - Anonymous credential systems

  - Regulatory compliance in privacy-enhanced systems

• D. Attack Detection & Defense

  - Advanced persistent threat analysis in blockchain networks

  - Machine learning for anomaly detection

  - Resilient consensus under DDoS attacks

  - Forensic analysis of blockchain attacks

  - Bug bounty program effectiveness studies

• E. Decentralized Application Security

  - Secure tokenomics design

  - DAO governance attack prevention

  - NFT marketplace security

  - DeFi protocol hardening

  - Decentralized identity system vulnerabilities

• F. Legal & Compliance Challenges

  - Smart contract legal enforceability

  - Cross-jurisdictional incident response

  - Security standards for blockchain systems (ISO/TC 307)

  - Cybersecurity insurance for blockchain

  - Darkweb blockchain abuse monitoring
