   > Today’s post is the next step in realizing our vision for the future of decentralized identities, [which we laid out last year](https://www.microsoft.com/en-us/microsoft-365/blog/2018/02/12/decentralized-digital-identities-and-blockchain-the-future-as-we-see-it/). We believe every person needs a decentralized, digital identity they own and control, backed by self-owned identifiers that enable secure, privacy preserving interactions. This self-owned identity must seamlessly integrate into their lives and put them at the center of everything they do in the digital world.

 * [Security analysis of a blockchain-based protocol forthe certification of academic credentials](https://arxiv.org/pdf/1910.04622.pdf) by Marco Baldi, Franco Chiaraluce, Migelan Kodra and Luca Spalazzi
   > Abstract—We consider a blockchain-based protocol forthe certification of academic credentials named Blockcerts,which is currently used worldwide for validating digitalcertificates of competence compliant with the Open Badgesstandard. We study the certification steps that are per-formed by the Blockcerts protocol to validate a certificate,and find that they are vulnerable to a certain typeof impersonation attacks. More in detail, authenticationof the issuing institution is performed by retrieving anunauthenticated issuer profile online, and comparing somedata reported there with those included in the issuedcertificate. We show that, by fabricating a fake issuerprofile and generating a suitably altered certificate, anattacker is able to impersonate a legitimate issuer andcan produce certificates that cannot be distinguished fromoriginals by the Blockcerts validation procedure. We alsopropose some possible countermeasures against an attackof this type, which require the use of a classic public keyinfrastructure or a decentralized identity system integratedwith the Blockcerts protocol.

+  One of the architectural components of Indy is called an Agent. This is software that acts on behalf of an identity owner to communicate off-ledger with other Agents. As Agent work continued with the development of message encryption standards, extensible message typing, and common protocols, interest grew in applying these concepts and practices to systems based on other ledgers. It became clear that the right future for Agent work was to e-xtract it from Indy project and add support for other ledger technologies to make that integration easier and more powerful. That work is now known as Hyperledger Aries.

+  > Identity is commonly cited as one of the most promising use-cases for distributed ledger technology. Initiatives and solutions focused on creating, transmitting and storing verifiable digital credentials will benefit from a shared, reusable, interoperable tool kit. Hyperledger Aries, the newest Hyperledger project (the13th!), is a shared infrastructure of tools that enables the exchange of blockchain-based data, supports peer-to-peer messaging in various scenarios, and facilitates interoperable interaction between different blockchains and other distributed ledger technologies (DLTs).
+
+[Hyperledger Aries: The Next Major Step Towards Interoperable SSI](https://www.evernym.com/blog/hyperledger-aries/)
+  > Aries was born out of the work on identity agents and identity wallets that began in the Hyperledger Indy project. As a company focused entirely on decentralized identity, Evernym was one of the original founders of the Sovrin Network and contributed the first code to the open source project Hyperledger Indy.

That work is now known as Hyperledger Aries.
+  >
+  > In addition to being able to support more ledger technologies than just Indy, Aries can work with multiple ledgers at the same time. This allows Agents to use each ledger according to the unique power offered by each, instead of requiring anchoring to only one ledger. In the future, Agents will be able to integrate not only with the recently announced Ion DID method, but also Ethereum, Hyperledger Sawtooth, Bitcoin, Hyperledger Fabric, and others.

+  > In two years since the introduction of Hyperledger Indy in 2017, the scope of work within its development community has far extended beyond what was initially set in its proposal. To clarify and keep track of new and existing peer-to-peer interaction code for secrets management, verifiable information exchange, and secure messaging across different blockchains and other distributed ledger technologies, Hyperledger Aries was set in motion.

+[The VON IIW 28 Demonstration: IIWBook](https://vonx.io/how_to/iiwbook)
+  > In late March 2019, the VON team created AgentBook to demonstrate the interoperability of independently created agents. These agents were able to successfully establish DID-based communication channels. Now, with IIWBook, we’ve added a (literal) new layer by extending the core of AgentBook with the ability to exchange verifiable credentials. Even more exciting, through collaboration with Streetcred and Spark New Zealand, we have a mobile agent (or two!).
