#ssi #did #web5 #dwn #didcomm How could DIDs talk to each other?

1. DID Auth
2. DID comm v2 https://lnkd.in/eMqDfa2w. Focus on low-level messaging and building blocks for protocols. One good example is WACI via did comm.
3. DWN - https://lnkd.in/eVQd7SrP. Full-scale protocol that introduces concepts of collections, threads, and permissions. Give insides about exchange and the persistence of messages in an IPFS. Decentralized Web Node - is an off-chain distributed protocol that allows not only messaging but permission access to data in ownership of other DIDs. We could have new interaction flows and protocols, but the complexity of the specification scares me. didcomm for not is more flexible and pluggable Important note on DWN - your diddoc should have a service endpoint that points to DWN nodes, so it is required to tune your diddocs.

The summary

• if you need something simple and move logic on the application side - go with did Auth and negotiate mainly on cryptography.
• if you are a protocol builder, look at #didcomm. And figure out the best persistence and ACL yourself. Maybe https://ceramic.network/ and https://litprotocol.com/ solve your needs.
• keep an eye on #DWN
