http://ssimeetup.org/trust-frameworks-ssi-interview-culedger-credit-union-mycuid-trust-framework-drummond-reed-webinar-9/ Drummond Reed, Chief Trust Officer at Evernym and Sovrin Foundation Trustee, features in this Webinar “Trust Frameworks and SSI: An Interview with CULedger on the Credit Union MyCUID Trust Framework”. To make SSI work, verifiable digital credentials must be something that websites, businesses, governments, and many others accept. To do that, they need assurances about who issued the credential under what rules. This “rulebook” for issuing digital credentials is called a trust framework. In this webinar, Evernym Chief Trust Officer Drummond Reed, chair of the Sovrin Foundation Trust Framework Working Group, will explain what a trust framework is and why they are are essential to SSI. Then he will interview executives of CULedger, the credit union blockchain consortia, about the MyCUID Trust Framework—the first global trust framework for proving membership in a credit union.

10. Trust Frameworks

11. A trust framework is…

A set of business, legal, and
technical rules which members
of a community agree to follow
in order to achieve trust online

Example: a credit card network
relies on a trust framework to
establish trust between the parties

Similarly, the trust in any SSI digital
credential will depend on the trust
framework under which it is issued

An SSI trust framework that
specifies what issuers will
issue what credentials under
what policies to achieve
desired levels of trust

27. 27
Any digital credential
intended to serve
more than one issuer/verifier
needs a domain-specific trust
framework
