Trust is essential for social interaction but levels of trust have declined in recent decades. Open badges, as representations of skills and achievements, could help to build trust in three ways:
1) By creating verifiable records of people's abilities that others can rely upon, potentially increasing trust between strangers.
2) Through the trust relationships between badge earners and issuers. If issuers are trusted sources, it reflects positively on the badges and earner.
3) By promoting transparency and providing evidence of competencies, open badges could help restore trust at societal levels that have eroded over time. However, badges are not currencies and are based on relationships rather than structural trust like currencies.
