The fifth Rebooting Web of Trust meeting concluded today. Led by Christopher Allen, we gather twice a year to advance standards for self-sovereign identity with trust rooted in distributed ledgers rather than federation. At this point there are five or six implementations based on four different blockchains that participate. Amazingly enough, after years of promoting UMA as a self-sovereign technology standard, this group has noticed and is poised to adopt UMA. The catalyst was the presence of Mark Miller as renowned evangelist for Capabilities-based security architectures. I suspect many UMAnitarains realize this is what we’ve been doing but Mark had not heard of UMA and I had not heard of Capabilities. A rushed summary of how UMA complements blockchain identity standards is here https://github.com/WebOfTrustInfo/rebooting-the-web-of-trust-fall2017/blob/m... References at the end of this paper provide background on Capabilities design and link to the early standardization work by the Decentralized Identity Foundation that will likely shift to adopt UMA. At this point, the HIE of One project is the only implementation of self-sovereign identity combined with UMA.
