The International Workshop on Blockchain for Decentralized Trust and Digital Identity (B4TI) addresses the fundamental challenge of establishing trust in digital environments. In an increasingly digital world, trust has become the cornerstone of all online interactions, yet the mechanisms to establish it reliably, efficiently, and equitably remain elusive. This workshop explores technological solutions to this core problem, focusing on approaches that enhance digital trust while respecting user autonomy. Self-sovereign identity (SSI) represents a paradigm shift in addressing these challenges, emphasizing user control over personal data and identity claims. While SSI is conceptually independent of any specific technology, decentralized technologies such as blockchain, Distributed Ledger Technologies (DLTs), and advanced cryptographic mechanisms offer promising tools to implement SSI principles in practice.

The Second International Workshop on Blockchain for Decentralized Trust and Digital Identity (B4TI 4.0), colocated with The 8th International Conference on Blockchain Computing and Application (BCCA 2026). The workshop focuses on trust models and architectures, blockchain and decentralized technologies, self-sovereign identity principles, cryptographic foundations, cross-trust transfer, traceability and data provenance, governance and standards, real-world applications, and the 2026 hot topic of Agentic AI and Autonomous Systems.
