   > The theme of this paper is the use of blockchain and distributed ledger technology for government services, and digital identity in relation to those. The scope for the state-of-the-art is global, but conclusions and recommendations focus on the significance and barriers in the European context. We assume general familiarity with blockchain and smart contract technology. For the purposes of this document, the essential features are that a blockchain has no central data controller or storage, and that it is an append-only immutable record store with reliable timestamping. More specific details, such as consensus mechanism, which vary from one blockchain network to another, are omitted.

 * [KEY EVENT RECEIPT INFRASTRUCTURE (KERI) DESIGN](https://raw.githubusercontent.com/SmithSamuelM/Papers/master/whitepapers/KERI_WP_2.x.web.pdf) Samuel M. Smith Ph.D. v2.54 2020/10/22, v1.60 2019/07/03 [[arXiv](https://arxiv.org/abs/1907.02143)]
   > An identity system based secure overlay for the Internet is presented. This includes a primary root-of-trust in self-certifying identifiers. It presents a formalism for Autonomic Identifiers (AIDs) and Autonomic Namespaces (ANs). They are part of an Autonomic Identity System (AIS). This system uses the design principle of minimally sufficient means to provide a candidate trust spanning layer for the internet. Associated with this system is a decentralized key management infrastructure (DKMI). The primary root-of-trust are self-certifying identifiers that are strongly bound at issuance to a cryptographic signing (public, private) key-pair. These are self-contained until/unless control needs to be transferred to a new key-pair. In that event an append only chained key-event log of signed transfer statements provides end verifiable control provenance. This makes intervening operational infrastructure replaceable because the event logs may be therefore be served up by ambient infrastructure. End verifiable logs on ambient infrastructure enables ambient verifiability (verifiable by anyone, anywhere, at anytime). The primary key management operation is key rotation (transference) via a novel key pre-rotation scheme. Two primary trust modalities motivated the design, these are a direct (one-to-one) mode and an indirect (one-to-any) mode. In the direct mode, the identity controller establishes control via verified signatures of the controlling key-pair. The indirect mode extends that trust basis with witnessed key event receipt logs (KERLs) for validating events. The security and accountability guarantees of indirect mode are provided by KERIs Agreement Algorithm for Control Establishment (KACE) among a set of witnesses.

   > Abstract—Decentralised identifiers (DIDs) and verifiable credentials (VCs) are upcoming standards for self-sovereign privacypreserving identifiers and authorisation, respectively. This focus on privacy can help improve many services and open up new business models, but using DIDs and VCs directly on constrained IoT devices can be problematic due to the management and resource overhead. This paper presents an OAuth-based method to delegate the processing and access policy management to the Authorisation Server thus allowing also systems with constrained IoT devices to benefit from DIDs and VCs.

We describe our conceptual model and architecture, and the protocol we used by extending FIDO's UAF in order to provide both strong authentication and strong authorization. We built a pilot implementation for U.K. NHS patients to validate our implementation. Patients were able to use a mobile phone with a fingerprint reader to access restricted NHS sites in order to make and cancel appointments and order repeat prescription drugs. Our initial user trials with 10 U.K. NHS patients found the system to be easy to use, and fingerprints to be preferable to using usernames and passwords for authentication.

End users typically have little control over their personal privacy, and data breaches effecting millions of users have already happened several times. We have implemented a proof of concept decentralized OpenID Connect Provider by marrying it with Self-Sovereign Identity, which gives users the freedom to choose from a very large pool of identity providers instead of just a select few corporations, thus enabling the democratization of the highly centralized digital identity landscape. Furthermore, we propose a verifiable credential powered decentralized Public Key Infrastructure using distributed ledger technologies, which creates a straightforward and verifiable way for retrieving digital certificates.

The signing key's corresponding public key is written to a public ledger and is declared as belonging to the issuer, so that anyone can use that public key to verify the signature embedded in a user's digital credentials and establish trust in a credential's authenticity.

+* [Blockcerts V3 Proposal - Verifiable Credentials & Decentralized Identifiers](https://community.blockcerts.org/t/blockcerts-v3-proposal-verifiable-credentials-decentralized-identifiers/2221)
+  > As the standards around Verifable Credentials are starting to take form, different favors of "verifiable credentials-like" data structures need to make necessary changes to leverage on the rulesets outlined and constantly reviewed by knowledgeable communities such as the W3C. The purpose of this paper is to identify all of the changes needed for Blockcerts to comply with the Verifiable Credentials (VCs) and Decentralized Identifers (DIDs) standards and to expand upon the additional benefits of using a blockchain in combination with Verifiable Credentials. This paper is meant to act as an explainer in which a formal specification can be created. This paper proposes multiple implementation options for several properties. The intention is that we can engage the Blockcerts / Verifiable Credential communities and see what fts best.

+  > At MATTR, we’ve been working hard on an exciting opportunity with the Government of British Columbia (BC Gov) in Canada. In June 2019, the BC Gov Verifiable Organisations Network team put out a “Code With Us” development bounty to integrate KeyCloak, their chosen enterprise Identity and Access Management (IAM) solution, with a new W3C standard called Verifiable Credentials. This work led to a solution that enables the use of Verifiable Credentials (VC) as a means of authentication that is interoperable with OpenID Connect (OIDC). We call this work VC-AuthN-OIDC. The output is an adapter that bridges these standards and enables a whole new set of capabilities through a simple extension of most modern IAM solutions.

+  > Hi - we’re looking into libp2p as a network stack for our application and exploring how we could integrate verifiable credentials (https://w3c.github.io/vc-data-model/ 2) infrastructure. A basic use case is that of a node being challenged to provide some specific credential to join the network. The bootstrap node handling the incoming connection should verify the credential with the issuer and complete the connection/bootstrap or terminate it.

+  > The Blockcerts Open Badges Draft Extension introduced a verifcation method based on those used by Verifable Credentials for the specifc use case of blockchain-anchored credentials. This paper expands that work and proposes a new option that can reside alongside existing Open Badges verifcation methods.
+* [Workday Credentials & WayTo™ By Workday](https://credentials.workday.com/docs/overview/)
+  > An issuer is any entity that wishes to relinquish and publicly attest to the veracity of data pertaining to a user. Public attestation comes in the form of a digital signature. When an issuer offers a credential to a user, Workday Credentials cryptographically signs the data in each credential with the issuer's private key before offering it to the user. The signing key's corresponding public key is written to a public ledger and is declared as belonging to the issuer, so that anyone can use that public key to verify the signature embedded in a user's digital credentials and establish trust in a credential's authenticity.
