Understand the Hyperledger Aries architecture and its components. Discuss the DIDComm protocol for peer-to-peer messages. Deploy instances of Aries agents and establish a connection between two or more Aries agents. Create from scratch or extend Aries agents to add business logic The envelope of the messages between agents has been standardized in the form of the DIDComm protocol. DIDComm describes how messages should be encrypted and decrypted in transport. When you can send messages from one agent to another, what do you send? The language in the messages, the format and the sequence of messages, are called the Aries protocol. Aries is an attempt to standardize the communication between agents

DIF starts DIDComm Working Group. 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 DID communications are the next important component in Aries. DIDComm ensures that agents can interact with one another for achieving the desired work. DID communications emerge with Aries project and the work on subsequent versions continues in the scope of a working group with the Decentralized Identity Foundation Developers that are interested in what DIDComm protocols are supported in ACA-Py should take a look at the protocols package. These should align with the corresponding aries-rfcs protocols. Decorators defined in aries-rfcs and implemented in ACA-Py can be found here

Understand the possibilities available through the implementation of Aries agents DIDComm JS Lib A shared effort with the HL Aries project to create a standardized means of authenticated general message passing between DID controllers. More information will be added soon DIDComm is the messaging protocol that provides utility for DID-based relationships. DIDComm is more than just a way to exchange credentials, it's a protocol layer capable of supporting specialized application protocols for specific workflows. Because of its general nature and inherent support for self-sovereign relationships, DIDComm provides a basis for a self-sovereign internet much more private, enabling, and flexible than the one we've built using Web 2.0 technologies DIDComm was born in the Aries project, and work on the next version continues within a working group at the Decentralized Identity Foundation. Protocols : The Aries protocols run on top of DIDComm and enable peer-to-peer application-level interactions among agents, and shows how they should be designed and documented Through this course you will come to understand the Hyperledger Aries architecture and its components and learn about the DIDComm protocol for peer-to-peer messages, how to deploy instances of Aries agents and establish a connection between two or more Aries agents, how to create from scratch or extend Aries agents to add business logic, and about the possibilities available through the implementation of Aries agents

This repo contains an example Aries Static Agent Library in Python. A static agent is a form of agent that can speak DIDComm at a basic level but its keys and connections are configured statically.

Together, they provide tools, libraries, and reusable components for creating and using independent digital identities rooted on blockchains or other distributed ledgers so that they are interoperable across administrative domains, applications, and any other silo

Enterprise blockchain alliance Hyperledger blockchain has not too long ago introduced the transition of Hyperledger Aries to lively standing Hyperledger Aries implements DID Communication (DIDComm) , a communication protocol similar to one first outlined by David Chaum . DIDComm is an asynchronous encrypted communication protocol that uses information from the DID document, such as the public key and their associated endpoint, in order to exchange secure messages; the authenticity and integrity of the messages are verifiable. DIDComm: Batphones today . DID-based messaging A stripped-down core of the Aries wallet-to-wallet communication protocol outlined in Aries was moved out of the Hyperledger Foundation recently.

As proposed in the Aries data attachment specification, it is possible to send data by reference through the DIDcomm messaging attachment, i.e., simply sending a link in the DIDComm message that can be fetched separately, whether by software or by human agency.

Bob will. Hyperledger Aries Cloud Agent Python (ACA-Py) is a foundation for building Verifiable Credential (VC) ecosystems. It operates in the second and third layers of the Trust Over IP framework (PDF) using DIDComm messaging and Hyperledger Aries protocols. The cloud in the name means that ACA-Py runs on servers (cloud, enterprise, IoT devices, and so forth), but is not designed to run on mobile. If Alice has a DID, then that's probably obvious >>> and DIDcomm would not be involved. >>> >>> The implication of building around the Aries agent definition is that >>> the agents of all four parties (Alice, Bob, Bob's Employer, Storage) would >>> need to deploy DIDcomm. >>> >>> Would this become an adoption problem for SSI Intuitively, the URI defined by the Aries project MUST be under the care of Hyperledger.

Trinsic's pricing model is based on DIDComm usage; we measure both incoming and outgoing DIDComm messages from any agent we're hosting on your behalf and charge for that usage based on the plan you've subscribed to. is still used, the connection made is ephemeral, meaning it disappears after. So, what would didcomm imply, and what would didcomms imply? Didcomm means communication in bulk, uncounted. It is also the appropriate adjective form. Didcomms means individual, countable didcomm events. Almost always, we want the non-plural, non-count sense

The Streetcred Identity Agent is based on the open source aries-framework-dotnet project; The Email Verification Service and IIWBook are instances of the open source Aries Cloud Agent - Python project. The repos for the services are: Email Verification Service; IIWBook; The DIDComm message family protocols implemented by the different agents to implement IIWBook include: DIDComm Protocol. DIDComm Content Protocols Protocols that define back-and-forth sequences specific messages sent between collaborating agents to accomplish some shared goal. DIDComm Content Protocol messages are delivered in DIDComm Envelope Protocol messages. DIDComm Envelope Protocol The method by which DIDComm Content Protocol messages are delivered, irrespective of the message content. The content message. Working experience with Aries and/or DIDComm is a strong advantage; Entrepreneurial attitude, builder and fast learner; Self-starter that can develop and contribute to a technical vision throughout the team; Likes to prototype/experiment, comfortable with ambiguity; Fluent in English (French is an asset). JOIN US ! We offer an exciting and challenging role, with great potential for personal. A custom scheme such as didcomm would be similar to how the mailto scheme works for email clients, the price paid by this format is if a user is sent a DIDComm message in a URL format that is prefixed with this didcomm scheme, invoking the URL on a device that has no identity wallet installed, would likely lead to some confusion for the user. As nothing on the device would recognize the scheme. Topic: Updates on Secure Data Storage on DIDComm. Sam Curren: Yes Orie Steele: The SDS Working Group is a joint effort between W3C and DIF. The purpose is to support the concept of data storage that's associated with DIDs. Orie Steele: The use cases are things like storing wallet contents, storing things associated with a DID, sharing access between DIDs. Orie Steele: It's a generic data.
