In DIDComm and the Self-Sovereign Internet , I make the case that the network of relationships created by the exchange of decentralized identifiers (layer 2 in Figure 1) forms a new, more secure layer on the internet. Communications over a DIDComm-enabled peer-to-peer network are as generative as the internet itself. Adaptability.

Agents speak a protocol called DIDComm (DID-based communication) that provides a secure communications layer for the exchange of identity information via verifiable credentials (VCs). Agents speak DIDComm to each other without a third-party intermediary (i.e., The agent does these activities using protocols that run on top of DIDComm.

Summary: DIDComm-capable agents provide a flexible infrastructure for numerous internet of things use cases. The infrastructure for supporting it is part of the heterarchical nature of DIDComm, including standardized support for sub protocols like Introduction. The workflows in these scenarios use DIDComm messaging to communicate.

Summary: Verifiable credentials have transport options other than DIDComm. This implies that DIDComm, the messaging protocol based on DIDs , underlies the exchange of verifiable credentials. Tags: identity ssi openid verifiable+credentials. In my discussions of verifiable credentials, I assume DIDs are the underlying identifier.

I was pleased to see these principles laid out clearly because many of them are often discussed (including by me) as properties of DIDComm, without the precision Oskar imposes. If complying with legal requirements means creating backdoors to DIDComm, I'd oppose it. Tags: identity ssi didcomm privacy cryptography.

SSI, more specifically DIDComm, creates a secure, identity-enabled, privacy-respecting messaging overlay on top of the internet. Tags: identity ssi web3 interoperability didcomm. I've no doubt that there will be adjacent areas with attractive profits that lead to other forms of centralization, as Tim suggests.

The Peer DID key event log can be shared with other parties in the relationship over DIDComm , a protocol that allows parties to a relationship to securely and privately share authenticated messages. The security and authority of a DIDComm channel are rooted in DIDs and their associated authentication factors.

There are two primary problems with the current pico engine that have to be addressed to make picos independent of the underlying engine: Picos are addressed by URL, so the pico engine's host name or IP address becomes part of the pico's address.

In contrast, the DIDComm protocol is symmetric and so it fosters one-to-one interactions that provide meaningful, life-like online relationships. DIDComm supports autonomic identity systems that provide a foundation for one-to-one, permissionless interactons. Like the cassette tape, DIDComm is a democratizing technology.

Without the self-sovereign internet, enabled through DIDComm, you might implement something that works as SSI, but it won't provide the leverage and adaptability necessary to creating a generative ecosystem of uses that creates the network effects needed to propel it to ubiquity.
