[Decentralized Identity & Trust Technology APAC/ASEAN Call](https://medium.com/decentralized-identity/decentralized-identity-meetings-for-the-apac-region-7221b9aad29)
> APAC and ASEAN engineers are historically under-represented in EU & US driven global efforts due to simple scheduling concerns — conference calls and other avenues of information sharing are often scheduled at inconvenient times for APAC and ASEAN participants. APAC and ASEAN engineers find it difficult to participate in communities that meet only between midnight and sunrise. This results in APAC and ASEAN solutions developing as parallels to their equivalent EU- & US-based global efforts, rather than as extensions of them or as interlocutors for them.
[DIF starts DIDComm Working Group](https://medium.com/decentralized-identity/dif-starts-didcomm-working-group-9c114d9308dc)
> Over the past few months, the DIF and Hyperledger Aries community have come together and agreed to work on a common work item aimed at developing secure communication based on Decentralized Identifiers (DIDs) — hence the name DIDComm, which is short for DID Communication. Significant prior work in developing a messaging-based communication protocol using DIDs has been incubating in the HyperLedger (HL) Aries community, with the progress of this effort evident in the resulting Aries RFCs. To address the requirements of a broader and more heterogeneous community we selected DIF as the place to pursue the next phase of work associated with this effort. Presenting the progress of DIDcomm to other relevant working groups will drive the interoperability between the various decentralized identity vendors and hence enabling a range of decentralized identity-related use cases.

title: Web Standards and the Emerging Decentralized ID Stack
excerpt: >
too many people complain about problems but dont step to Fix It!. There are certainly a lot of flawed standards but they make interoperability possible not perfect but possible. If you havent used them then you have no right to complain that they are too complex, too simple (even in the same standard) or too domain specific or any of the other rants and raves that go on.
If youre willing to put up with a lot of work for incremental improvements then step up and join a standard. Whether that is a (relatively) fast moving standard group like OASIS (www.oasis-open.org) or a slower but more international group like ISO you will learn. Youll also benefit from working with experts. These experts donate their time and are more than happy to provide ideas, guidance, and leadership.

> Youre familiar with digital identity standards like OpenID Connect, OAuth, and User-Managed Access, fundamental elements of privacy and security on the internet. But have you ever wondered how they came to be? A lot of work on these protocols went on (and goes on) behind the scenes at the Internet Identity Workshop (IIW), a bi-annual gathering of identity experts where we work on improving the identity systems that make the web run. Its a great event thats flown under the radar, so Im excited to share a new documentary on IIW, “Not Just Who They Say We Are: Claiming our identity on the Internet”. This short film shines a light on the stealth community of “Identerati” at IIW that are defining and refining digital identity.

> Identity management systems (IDMSs) are widely used to provision user identities while managing authentication, authorization, and data sharing both within organizations as well as on the Internet more broadly. 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.

> First, you will see the Issuer, Holder and Verifier. This is the archetypal pattern of the decentralized architecture. An issuer issues something to a holder, who then presents it to a verifier, who make a decision. A simple example: government(issuer) issues you a passport (holder), which you present to a border control officer (verifier) who lets you through the gate. When you look at all the use cases (described above), they all fall into this pattern.\

[Decentralized Identity & Trust Technology APAC/ASEAN Call](https://medium.com/decentralized-identity/decentralized-identity-meetings-for-the-apac-region-7221b9aad29)
> APAC and ASEAN engineers are historically under-represented in EU & US driven global efforts due to simple scheduling concerns — conference calls and other avenues of information sharing are often scheduled at inconvenient times for APAC and ASEAN participants. APAC and ASEAN engineers find it difficult to participate in communities that meet only between midnight and sunrise. This results in APAC and ASEAN solutions developing as parallels to their equivalent EU- & US-based global efforts, rather than as extensions of them or as interlocutors for them.
[DIF starts DIDComm Working Group](https://medium.com/decentralized-identity/dif-starts-didcomm-working-group-9c114d9308dc)
> Over the past few months, the DIF and Hyperledger Aries community have come together and agreed to work on a common work item aimed at developing secure communication based on Decentralized Identifiers (DIDs) — hence the name DIDComm, which is short for DID Communication. Significant prior work in developing a messaging-based communication protocol using DIDs has been incubating in the HyperLedger (HL) Aries community, with the progress of this effort evident in the resulting Aries RFCs. To address the requirements of a broader and more heterogeneous community we selected DIF as the place to pursue the next phase of work associated with this effort. Presenting the progress of DIDcomm to other relevant working groups will drive the interoperability between the various decentralized identity vendors and hence enabling a range of decentralized identity-related use cases.
