  • handshake protocol
• garbage collection:
  • how to infer causal stability as presented here
• ACLs:
  • should we implement “Access Control for Weakly Consistent Data Stores” (see discussion in https://github.com/ipfs/dynamic-data-and-capabilities/issues/25)?

Other notes

@fritzy Peer identity: There is working code with DID DOcuments and creating proofs, and an identity service, in shipyard that can be converted to a REST DID-Method. (add link later). @satazor questioned about the need for a centralized server to make it work.

@pgte mentioned that a method to support several DID methods would be an option.

@satazor mentioned the concept of an identity hub: https://github.com/decentralized-identity/hubs/blob/master/explainer.md#stores

@diasdavid MFS, you can create virtual directories, but can also me used as a UNIX file system. IPFS Drive,1,2,3. Read about MFS, Files API and Shared Volumes at:

• Great video - https://www.youtube.com/watch?v=FX_AXNDsZ9k
• https://github.com/Gozala/ipfs-drive
• https://github.com/ipfs/specs/issues/174
• https://github.com/ipfs/specs/issues/98
• in a go-ipfs node, do ipfs files —help
• https://github.com/ipfs/specs/issues/88 (issue about the spec not existing yet)
• https://github.com/ipfs/js-ipfs-mfs wip in js

Dream API:

• The class that represents the type adds the function to do access control.
• See how the Dream API relates to Identity.

@diasdavid @pgte discussed using accumulators (need help to complete here)

Discussion:

• @pgte suggests making short summaries about the various Identity platforms (uPort, Peer-Identity, btcr, etc).
• Use a passphrase on Identity, or rely on device keys?
• View each proposal's attack vectors and analyze them.
• Analyze The Update Framework
• Docker Notary
• Key rotation discussion - https://github.com/ipfs/specs/issues/31

• Privacy issues:

  • Know who has access to a document

  • Know what the document has

  • Encryption at rest & encrypt at transmission
