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.

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. Things get really complicated when you start mixing authz/authn/claims/permissions into a Verifiable Credential.

Simply put because security is hard and trying to push square pegs into round holes often times leads to bugs which are elevated to mission critical authentication/authorization bypass vulnerabilities. By designing around a fit for purpose data model with a well defined problem being solved it allows for us to be much more precise about where we believe extensibility is important versus where normative statements should be made to simplify the processing of the data models. By extension this leads to a simpler security model and likely a much more robust design with fewer vulnerabilities.,,https://kyledenhartog.com/comparing-VCs-with-zcaps/,,Post,,,Comparisons,,,,,,,,2021-09-25,,,,,,,,,,,,, +VCs,CCG Mailing List,,,Dave Longley,CCG,,,,,Re: VCs - zCaps / OCap a Discussion,"TL; DR: My current view is that the main confusion here may be over the difference between VCs and LD Proofs, not VCs and ZCAPs.

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. Rather than attempting to resolve this potentially unresolvable question, we propose a rubric — which is a scoring guide used to evaluate performance, a product, or a project — that teaches how to evaluate a given DID method according to one’s own requirements. 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,The DID Methods,,,,,,"ERC1056, secp256k1",,2022-11-07,,,,,,,,,,,,, +Decentralized Identifiers,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,The DID Methods,,,,,,"did:ethr:, secp256k1",,,,,,,,,,,,,,, +Decentralized Identifiers,Digital Bazaar,did:v1:,,,,,,,,did:v1:,"There are two primary classes of DID-based identifiers in Veres One.

- ION is public and permissionless - the system is decentralized, no company, organization, or group owns/controls the identifiers and DPKI entries in the system, and no one dictates who can participate.
- ION doesn't introduce new tokens/coins - Bitcoin is the only unit of value relevant in the operation of the on-chain aspects of the ION network.
