What if all our decentralized apps and platforms could share trust/ratings/attestation information, in the form of portable cryptographically signed claims? What if this self-sovereign, user owned and controlled, privately sharable trust network could become the backbone to unite our many disparate decentralized web apps and platforms? These are the goals of Trust Graph, and its reference implementation built on Holochain.

In this talk we will cover:

• TrustAtom format: source, target, semantic content, normalized scalar value
• Quick survey of the ecosystem of similar protocols
• Use cases, including the potential to tackle major global challenges
• An example illustrating Trust Graph "rollups" for caching Trust Graphs in TrustAtoms
• Trust Graph on Holochain: using Holochain links to allow for searchable TrustAtoms
