COMPSAC 2026 BlockChain: Emerging Systems & Theory (BEST)

Blockchain is a decentralized, distributed ledger technology that records transactions across multiple nodes showing some key characteristics, such as the lack of a central authority, Transparency, since transactions are publicly verifiable, Immutability, since once recorded, data cannot be changed, and Security, since data are encrypted and validation is based on consensus algorithms. Blockchain technology is having a deep impact on the transformation of society by enabling the development of several applications in different fields. Blockchain and Artificial Intelligence are converging to address some of today’s most pressing technological challenges. Blockchain offers transparency, security, and data integrity, while AI enables intelligent decision-making. Their integration opens new directions for trustworthy data-driven systems, decentralized learning, and secure automation. Furthermore, blockchain improves financial access, government transparency, supply chain traceability, healthcare data security, and digital identity control. It also empowers creators through NFTs and introduces new economic models. However, challenges like regulation, scalability, and digital inequality remain.
