Traditional identity systems typically suffer from single points of failure, lack of interoperability, and privacy issues such as encouraging mass data collection and user tracking. Blockchain technology has the potential to support novel data ownership and governance models with built-in control and consent mechanisms, which may benefit both users and businesses by alleviating these concerns; as a result, blockchain-based IDMSs are beginning to proliferate. This work categorizes these systems into a taxonomy based on differences in architecture, governance models, and other salient features. We provide context for the taxonomy by describing related terms, emerging standards, and use cases, while highlighting relevant security and privacy considerations.

This method helps to ensure that no third-party can compromise the integrity and security of the system as a whole. Entities can use the system to safely authenticate each other and validate keys and certificates. Centralized key management systems (CKMS) manage key and certificate creation, signing, and validity. Specific problems arise when these authorities become unavailable, or the data they control becomes corrupted or known. Central authorities often become choice targets for attackers. This document proposes to meet these requirements with a decentralized blockchain ledger for providing an oracle of trust and leave control over all keys with end users. The use of a blockchain permits globally readable identifiers and public data to be shared in a secure manner that is not vulnerable to the man-in-the-middle attack or system wide compromise and permits consumers to be self-sovereign. This leaves consumers with the task of key management and protection.

- Multiple currencies on the blockchains
- Certifications in the form of some kind of NFT issued by the issuer.
- Limited supply tokens or NFTs that are “expired” when you use them
- Open Credential Publisher framework was suggested

because of the delegation. With that in mind, looking at the semantics only
of the system VCs in my opinion weren't optimally designed for permission
tokens. This difference between the two requires that an implementation
that wants to support both claims tokens and permissions tokens has to
grapple with the different mental model that arise when trying to stuff
these things together. This introduces additional complexity. Additionally
it leads to weird statements that are being made where it's difficult to
tell if the VC is behaving like a claims token or a permissions token.

Yes, exactly this. Exactly what Kyle states above is the reason why it's so complicated (and thus dangerous) to use VCs as permissions tokens.

This is one of the primary reasons that we separated out the Authorization Capabilities work from the Verifiable Credentials work.

This debate about decentralization is a continuation of a similar, ongoing argument in cryptocurrency circles: the question of whether or not bitcoin or ethereum is more decentralized is a nearly endless source of argument.

Our goal is to develop a guide that minimizes judgment and bias. Rather than advocating particular solutions, the rubric presents a series of criteria which an evaluator can apply to any DID method based on their particular use cases. We also avoid reducing the evaluation to a single number because the criteria tend to be multidimensional and many of the options are not necessarily good or bad: it is the obligation of the evaluator to understand how each response in each criteria might illuminate favorable or unfavorable consequences for their needs.

In the Ethereum community, a pattern known as ERC1056 (see [2]) utilizes a smart contract for a lightweight identity management system intended explicitly for off-chain usage.

The described DID method allows any Ethereum smart contract or key pair account, or any secp256k1 public key to become a valid identifier. Such an identifier needs no registration. In case that key management or additional attributes such as ""service endpoints"" are required, they are resolved using ERC1056 smart contracts deployed on the networks listed in the registry repository.

Since each Ethereum transaction must be funded, there is a growing trend of on-chain transactions that are authenticated via an externally created signature and not by the actual transaction originator. This allows for 3rd party funding services, or for receivers to pay without any fundamental changes to the underlying Ethereum architecture. These kinds of transactions have to be signed by an actual key pair and thus cannot be used to represent smart contract based Ethereum accounts. ERC1056 proposes a way of a smart contract or regular key pair delegating signing for various purposes to externally managed key pairs. This allows a smart contract to be represented, both on-chain as well as off-chain or in payment channels through temporary or permanent delegates.",,https://github.com/decentralized-identity/ethr-did-resolver/blob/master/doc/did-method-spec.md,,Specification,,Ethereum,DID Methods,,,,,,"ERC1056, secp256k1",,2022-11-07,,,,,,,,,,,,, DID Methods,DIF,,,,,,,,,DID resolver for Ethereum Addresses with support for key management (and DID reference implementation),This library is intended to use ethereum addresses or secp256k1 publicKeys as fully self-managed Decentralized Identifiers and wrap them in a DID Document,,https://github.com/decentralized-identity/ethr-did-resolver,,Code,,Ethereum,DID Methods,,,,,,"did:ethr:, secp256k1",,,,,,,,,,,,,,, DID Methods,Digital Bazaar,did:v1:,,,,,,,,did:v1:,"There are two primary classes of DID-based identifiers in Veres One.

As such, individually deployed entities in the network – nodes – have a strong notion of identity. This concept is instrumental in network communication. Similarly, the data-replication model implemented in Corda is different to that of a conventional public blockchain, which makes all in-ledger data visible to all network participants. In Corda, data are distributed to a configurable subset of network members only.

Despite the large amount of valuable standardization work on identity, it is unclear how user agents such as Web browsers can interact with both identity-consuming applications and server-side federated identity services, and many current identity specifications either assume or underspecify secure authentication in the browser. The key missing component to enable trusted identity on the Web is likely then to be found in user-centric cross-browser standards for secure authentication and session management.",,https://www.w3.org/2011/identity-ws/report.html,,Report,,,W3C ID History,,,,,,,,2011,,,,,,,,,,,,, W3C,W3C,,,,Channy Yun,,,,,A draft charter of Web Identity,The W3C has prepared Web Identity working group and make a draft charter.

Therefore, users have to give away a lot of information about themselves to many different services. The point is that the users lose control of their identity on the web, by filling a lot of forms (e.g., through subscriptions). Privacy on the Internet is extremely important and must remain. Personal information is used by services we, sometimes, don't even know about, and it is a real problem. The aim of this group would be to think about new ways to identify individuals over the internet using trusted web based identities embedded directly into the core protocols of the web.

Most of you don’t know what WebAuthn is yet, but many of you will feel the impact in short order. In fact, I will go so far as to say that WebAuthn may change how we all authenticate to the resources we use every day.

We live in a world where the best parts of our individual local hardware and software collection are rarely leveraged to make cloud security decisions. This is because there has never been a vendor-agnostic and privacy-preserving way for cloud resources to interact with individual hardware configurations in any generic way. Until now!

With WebAuthn, any web entity can call a simple Javascript API and ask for a cryptographically secure credential. What happens next is pretty cool – the world’s browsers have worked with the world’s operating system makers and the world’s hardware manufacturers, so that when a website asks for a credential, the browsers work with the underlying platform to securely locate compliant local hardware and talk to it!",,https://techcommunity.microsoft.com/t5/identity-standards-blog/why-webauthn-will-change-the-world/ba-p/482286,,Post,,,Main,,,,,,,,2019-04-19,,,,,,,,,,,,, WebAuthN,ZDNet,,,,,,,,,W3C finalizes Web Authentication (WebAuthn) standard - ZDNet,"WebAuthn allows users to register and authenticate on websites or mobile apps using an ""authenticator"" instead of a password.

Read on for the big picture of how the W3C WebAuthn and FIDO2 CTAP2 specifications interact. We will start with the industry standards perspective, and then at the end we will summarize how Microsoft implements the various roles.
