#RWOT8

In December 2018, as part of our ongoing effort to support and grow the community, Rebooting the Web of Trust incorporated as a not-for-profit mutual- benefit association.

A key benefit of this new structure is a greater opportunity for participation by community members.

This workshop, Rebooting the Web of Trust VIII, is the first opportunity to become a paying member and directly support the new organization. Members receive discounts at all Rebooting the Web of Trust events and have additional opportunities to participate in organizational governance.

Annual Membership: US$100 Workshop Discount: US$50

Purchase the bundled membership with your ticket to receive $50 off this workshop and all the benefits of a full-year membership in Rebooting the Web of Trust. These discounts will continue; our goal is to assure that anyone who attends two workshops in a given year gets their membership fee back in the form of discounts. A B O U T R E B O O T I N G T H E W E B O F T R U S T , I N C

A 501(c)(6) mutual benefit association incorporated in the United States, Rebooting the Web of Trust, Inc. gathers passionate professionals to define, explore, and advocate for decentralized identity. We hold workshops and salons where we discuss, collaboratively write, and ultimately publish ground-breaking papers to help shape the future of identity.

Decentralized identity allows individuals to directly manage how others recognize, remember, and respond to us. Instead of dependence on state- or corporate-issued IDs— acting as both root identifiers and reliable credentials—decentralized identity gives individuals a way to create and manage identifiers that can be used to construct reliable identity on demand. Individuals use these identifiers to create and selectively disclose both self-asserted claims and credentials from trustworthy authorities, with any receiving party—without the unnecessary privacy risks found in legacy identity architectures.

The goal is to define a privacy-centric and censorship-resistant identity architecture where no single entity can deny its use and well-known authorities like local governments and sovereign states can provide reliable attestations without revealing to those authorities when and where such attestations are used.

Our goal is ubiquitous individual-controlled identity without ubiquitous surveillance. This is a work in progress.

We are a volunteer-driven membership organization. We depend on the passion of professionals and the support of sponsors to realize our goals. If you'd like to be a part of building a better identity architecture for a better world, please join us.
