Emerging Trust Technologies
Summary
This chapter looks beyond blockchain to the next generation of trust technologies. Students will examine zero-knowledge proofs, verifiable credentials, decentralized identifiers, and self-sovereign identity as alternatives or complements to blockchain. The chapter also covers regulatory considerations including GDPR compliance, data sovereignty, and the right to be forgotten — challenges that blockchain's immutability makes particularly difficult to address.
