Self-Sovereign, Blockchain and Decentralized Identity Resources

A good self‐sovereign identity system will allow individuals to directly influence how companies, governments, and others correlate our interactions across different services and locations by default. It won’t fix all identity problems nor preclude alternative identity approaches, but it will put the individual in control of most uses of identity and give organizations a simpler, easier, more ethical way to use identity to improve how they provide services and products. When successful, it will not only enable individuals to exercise greater control over how companies and governments keep track of us, it will also illuminate those situations where self‐sovereign identity is restricted, facilitating a conversation about when and where such limits are appropriate. Joe Andrieu -A Technology‐Free Definition of Self‐Sovereign Identity

This is a gathering of educational materials around decentralized, self-sovereign, and blockchain identity. Its an index for research, training, developers, students, end-users, investors, and the enterprise to more easily learn and navigate the decentralized identity landscape.

Introduction^

Thanks to those who are working to make digital identity, and the world, a better place.

/blockchain-identity and /indy-sovrin-evernym^

/awesome-decentralized-id/indy-sovrin-evernym is another list that naturally grew from this one; focused on Hyperledger Indy's protocol, governance, and ecosystem. I've also worked on /peacekeeper/blockchain-identity and included some of its resources here. Ideally these lists will all compliment each-other.

For now, I'm becoming more familiar with all of this material, and how it fits together in the decentralized identity space. I expect to be actively engaged building this repository for the next month or so, and look forward to it growing along with decentralized identity (irl) over the coming years.

How I got into Decentralized Identity^

I was initially introduced to blockchain identity when offering research and writing services on a popular freelance site. The first was 3500-word essay on "Blockchain and the United Nations," where I learned of Bitnation and the SDGs. Another was a 1500 word report on blockchain identity, giving me a broad view of the sector. Besides that I've written a few articles considering the architecture, and historical background of Hyperledger Indy. Throughout that time, I collected a ton of quality information on decentralized id, Hyperledger Indy, and the surrounding ecosystem.

I also collect resources on nearly every subject in crypto, which I'm slowly entering into a database, to power a web-app for search, and navigation by tags, etc. Creating these lists has become an essential part of my process as a writer. Check out some of my other projects.

Although initially began as a result of freelance gigs, my work on this repository has been a personal investment of time, building my brand as a research consultant, and in support of anyone trying to make sense of the SSI\DID ecosystem. Decentralized Identity is one of my favorite subjects in tech. However, I have a variety of research interests, and I'm always interested in learning new ways to earn from that research.

History^

This isn't meant to be a complete history, but to provide enough relevant backround to provide context for the this arrangement of resources.

The Augmented Social Network and the IDCommons^

  • The Augmented Social Network: Building Identity and Trust into the Next-Generation Internet, presented at the June 2003 Planetwork conference and published in First Monday the Peer-Reviewed Journal on the Internet 8/4/03.

    "This paper proposes the creation of an Augmented Social Network (ASN) that would build identity and trust into the architecture of the Internet"

Ideas from the ASN were the foundation of much that followed. The Identity Commons (2001-Present) was originally created by Owen Davis and Andrew Nelson in 2001 to evangelize the creation of a decentralized user-centric identity infrastructure and to address the resulting social trust issues.

"Their most important contribution may have been the creation, in association with the Identity Gang, of the Internet Identity Workshop (2005-Present) working group. "[ϟ]

Internet Identity Workshop^

In 2005, Kaliya Young[T], Phil Windley[T][V][G], Drummond Reed[T][B], and Doc Searls[T][B] hosted the first Internet Identity Workshop(IIW)[T] in Berkeley to discuss "architectural and governance proposals for Internet-wide identity services and their underlying philosophies." -Announcing IIW 2005

Since then, the IIW has met bi-anually, actively supporting the development of the identity software-ecosystem, including OpenID('05), OpenID 2.0('06), OAuth('10), FIDO('13) and OpenID Connect('14).

IIW participants began the effort towards creating a truly "user centric identity," in contrast to identity solutions whos focus has been fulfilling the needs of the enterprise. The pioneers of decentralized identity have long struggled against the "identity silo paradox," that while the identerati continually work on solutions to break up these silos, the enterprise has had a strong financial incentive to retain them.

  • What is IIW? [ϟ][ϟ] short film about the identirati[ϟ] (a term for those working on identity standards for the purpose of breaking up id data silos, dating back to at least 2006).

In April of 2014, the European Parliament demonstrates strong support for the GDPR, which passes back and forth through the European Council, Commision and Parliment throught the rest of the year.

8/14 The Credentials Community Group[ϟ] forms, hosted by World Wide Web Consortium(W3C)[T] [G] : "to forge a path for a secure, decentralized system of credentials that would empower both individual people and organizations on the Web to store, transmit, and receive digitally verifiable proof of qualifications and achievements." —proposed by Manu Sporney[T] (of digitalbazaar.com)

What is Sovereign Source Authority? shows an early use of 'sovereign' in relation to our internet identities. The term "Self Sovereign Identity" started becoming widely used in 2014.[ϟ][ϟ]

Bitnation and the United Nations^

9\15 Bitnation "seeks to establish the concept of 'world citizenship' via a bitcoin based identity, offering 'Blockchain Emergency IDs' to refugees. [>]

The same month, the UN unveiled it's Agenda for Sustainable Development:

  • Promote peaceful and inclusive societies for sustainable development, provide access to justice for all and build effective, accountable and inclusive institutions at all levels
  • Substantially reduce corruption and bribery in all their forms Develop effective, accountable and transparent institutions at all levels
  • By 2030, provide legal identity for all, including birth registration
  • Ensure public access to information and protect fundamental freedoms, in accordance with national legislation and international agreements—(emphasis mine)
  • DIGITAL IDENTITY AS A BASIC HUMAN RIGHT
  • AID:Tech [T] — "is a voucher and digital identity solution for refugees. A digital record of a person's identity is stored on a smart card, along with various additional information. Blockchain technology is used to distribute all resources in a highly traceable manner." (another early example of blockchain for humanitarian aide)

Rebooting the Web Of Trust^

In relation to SSI, 'Web of Trust' is a network of relationships that attest to our identity claims. Each party attesting to your identity information becomes a strand in your web of trust.

The first Rebooting Web of Trust(RWoT) workshop was held during November 2015; attracting the likes of Vitalik Buterin, Peter Todd, Gregory Maxwell, Joel Dietz, Christopher Allen, and Jon Callas, according to Andreas Antonopolis.

That workshop, produced 5 technical white papers:
5 WoT-usecases • Decentralized PKI • Smart Signatures • Creating a New World of Trust

The Web of Trust is a buzzword for a new model of decentralized self-sovereign identity. It’s a phrase that dates back almost twenty-five years, the classic definition derives from PGP [...] the vibrant blockchain community is also drawing new attention to the concept we aim to reboot it. - Rebranding the Web of Trust

At the end of 2015, the Department of Homeland Security announced that it had funds available for the development of Blockchain Security and Identity Verification Technologies.

ID2020 and the GDPR^

  • 4/16 the EU adopted the GDPR to be enacted as law May 2018.
  • The second RWoT workshop ran in conjunction with the UN's ID2020 Summit in New York that May; clearly a significant time for decentralized identity:

    1.1 Billion people live without an officially recognized identity — This lack of recognized identification deprives them of protection, access to services, and basic rights. ID2020 is a public-private partnership dedicated to solving the challenges of identity for these people through technology. - id2020.org

  • Identity Crisis: Clear Identity through Correlation
  • Christopher Allen[info] details the overarching history of internet idenitity standards in his seminal work (submitted to ID2020\RWoT workshop):
    • The Path to Self-Soverereign Identity[ϟ] details the history of identity standards leading up to self-sovereign and details the 10 principles of self-sovereign identity.

      I am part of the team putting together the first ID2020 Summit on Digital Identity at the United Nations

  • Identity System Essentials 3/16 (Original Evernym Identity WP also submitted to ID2020\RWoT workshop)

Evident from the other whitepapers submitted to the second RWoT Workshop, the DID identifier had begun to emerge:

  • Decentralized Identifiers (DIDs) and Decentralized Identity Management (DIDM)

    "Decentralized Identifiers (DID) stored in a permissioned blockchain enable principals to directly control their own identities with cryptographic proofs and secure, addressable network endpoints. DIDs further enable a Decentralized Identity Management (DIDM) infrastructure that will empower people and organizations to securely and confidentially manage and assert their identities."

  • Requirements for DIDs

    "Respect Network is conducting a research project for the U.S. Department of Homeland Security, HSHQDC-16-C-00061, to analyze the applicability of blockchain technologies to a decentralized identifier system. Our thesis is that blockchains, or more generically distributed ledgers, are a potentially powerful new tool for “identity roots” — the starting points for an Internet identity. However “blockchain identity” may not fully address the core security and privacy principles needed in a complete identity system. In this case DIDs — Decentralized Identifiers rooted on a distributed ledger — may end up being a foundational building block for higher level identity management solutions. -

  • At this point in time DLT innovation, the United Nations Sustainable Development Goals, and the EU GDPR all came together supporting a core identirati tenant: Eliminating id data silos and empowering users regarding digital identity.

  • @ChristopherA on DID adoption

    "22/ Over a dozen companies and organizations, using multiple blockchains (Bitcoin, Ethereum, Hyperledger, etc.), have committed to deploying DIDs, including IBM, Microsoft, Digital Bazaar, Consensys, Evernym, Learning Machine, British Columbia, and more:" —How blockchain could solve the internet privacy problem

  • Veres One DID Method 1.0 [D] (veres.one) — a permissionless public ledger designed specifically for the creation and management of decentralized identifiers (DIDs)
  • Blockstack DID Spec[ϟ] Blockstack is a network for decentralized applications where users own their identities and data. Blockstack utilizes a public blockchain to implement a decentralized naming layer, which binds a user's human-readable username to their current public key and a pointer to their data storage buckets.
  • BTCR DID Method — The Bitcoin Reference DID method (did:btcr) supports DIDs on the public Bitcoin blockchain. The Bitcoin Reference method has minimal design goals: a DID trust anchor based on the Bitcoin blockchain, updates publicly visible and auditable via Bitcoin transactions, and optionally, additional DID Document information referenced in the transaction OP_RETURN data field. No other Personal Identifiable Information (PII) would be placed on the immutable blockchain.
  • Interplanetary Identifiers IPID - Implementation of the DID spec over IPFS (Interplanetary File System)
  • Peer DID Method Spec
  • Spidchain [wp]
    • "offers a platform for self-sovereign identity, including desktop and mobile apps for end-users. It uses Decentralized Identifiers (DIDs) - backed by optionally Bitcoin or Ethereum - to implement a marketplace for verifiable claims. The Spidchain applications allow individuals to create, recover, and revoke DIDs, to authenticate, to sign and verify files and claims, and more."

  • Schema — a collaborative, community activity with a mission to create, maintain, and promote schemas for structured data on the Internet. Schema.org vocabulary can be used with many different encodings, including RDFa, Microdata and JSON-LD. These vocabularies cover entities, relationships between entities and actions, and can easily be extended through a well-documented extension model. Over 10 million sites use Schema.org to markup their web pages and email messages. Many applications from Google, Microsoft, Pinterest, Yandex and others already use these vocabularies to power rich, extensible experiences."

Additional Thought around Identity

  • Decentralized Identity Trilemma

    There seems to exist a trilemma in decentralized identity analogous to @Zooko's triangle. None of the existing solutions are at the same time: 1) privacy-preserving, 2) Sybil-resistant 3) self-sovereign -[T]

  • Proof of Thought (PoT)
  • Queer Privacy

    Stories about using the Internet as a tool to find out more about yourself, and as a tool to express and empower; about the dangers of Internet censorship and about the practical realities of maintaining multiple distinct digital identities.

  • @SarahJamieLewis Twitter thread on Identity

    Any technology which relies on the existence of, or attempts to create a, global, unique identity is oppressive by design. Stop" innovating" oppressive structures.
