    • 1324 - Handle unpadded protected header in PackWireFormat::get_recipient_keys – only askar and multi-tenancy

    • 1325 - fix: error on deserializing conn record with protocol – DID Exchange specific

• Milestone: Connection established with Aries Framework Go using a did:orb DID

• Supporting connecting to multiple Indy ledgers - @Shaanjot Gill - Design Doc: https://hackmd.io/@gbeoESqjRxm7oQacVc_3OQ/Sy_Xh3r0d

  • Actions:

    • @Daniel Bluhmto do a hackmd doc design to meet mediator-centric requirements, ideally with a narrative on push notification handling

    • @Andrew Whiteheadto do a hackmd doc design to meet scalability requirements - https://hackmd.io/OF5o0idQTwi_T_3eWkDvmw

    • Ideally, incorporated into the above, but if not, a third design doc, covering the use of the event bus with the outbound queuing

• Double Signature with eIDAS?

  • Background: https://www.slideshare.net/FIDOAlliance/introduction-to-fido-and-eidas-services

  • SICPA - For the eSSIF program, with json-ld credential we are adding double signature, the normal + eIDAS
