In a live demo, Gore walked through how a new developer with no prior credentials spins up an identity, joins a Linux Foundation community, and then establishes a relationship with another participant using pairwise DIDs. Once that relationship exists, the two sides can exchange richer, verifiable relationship credentials (VRCs) that record facts such as when the relationship started, the level of trust it reflects, and how long the credential should remain valid.

The Games were full of contrasts. From a sporting perspective, the gentle gracefulness that I observed at the figure skating was offset by the full-on brutality of ice hockey brawls, while the delicate precision of curling was juxtaposed by the frantic chaos of short-track speed skating. From a geographical and cultural perspective, Livigno, which is perched high up in the Alps close to Switzerland, seemed like a giant playground for modern snow sports – geared towards those who like to twist and twirl high in the sky – while Cortina, in the Dolomites, was far more old-fashioned and populated by the traditional skiing establishment. Milan, meanwhile, featured a cluster of modernist, edge-of-town arenas, with international fans happily catching the metro to and from the events. But, in my experience, transportation wasn’t always so convenient. The huge amount of travelling between venues – I went to all but one – was exhausting and getting a late night bus over the mountains between Livigno and Bormio in a blizzard felt a bit hairy.
