Status Integration §

• achieved:
  • finalizing extracting ArchiveService to a new hierarchy:
    • ArchiveService and ArchiveServiceBackend, where ArchiveService also includes the ArchiveServiceBackend interface, thus acting as a proxy/facade
    • new ArchiveManager with technology-independet history archive-related operations
    • new ArchiveManagerTorrent with BitTorrent specific operations
    • new ArchiveManagerLogosStorage with LogosStorage specific operations
  • most of the work is happening on the new LogosStorage integration branch feat: status go codex integration#7201 from which I am simulataneously porting everything down to the refactor: prepare ArchiveService for LogosStorage extension#7312
• next:
  • finalize the #7312 and get it merged
  • build system

Testnet filesharing client §

• achieved:
  • Block exchange protocol

    • Managed to make the tests run.
    • Cleaning up for PR.
    • Few tests are failing but most of them are passing.
  • Bug fixes:
    • Node freezing on shutdown as cancellation not propagated.
    • Node crashing on shutdown as iterators not disposed properly.
  • Remove callbacks from synchronous calls in libstorage.
  • discv5 replacement with libp2p Kademlia DHT
    • investigation completed
      • would lose UDP support
      • SPRs not supported in kad dht for provider records
    • initiated replacement
• next:
  • Block exchange protocol
    • Decouple manifest fetching from block exchange
    • Download manager and Scheduler API cleanup
    • Multi-download per CID
  • E2E testing:
    • Submit PR with the Marketplace refactor work
    • Look into the failing tests
    • Potentially setup Kubernates cluster to run the tests on.
  • discv5 replacement with libp2p Kademlia DHT
    • investigate difficulty in supporting SPRs for provider records, possibly allowing consumer of libp2p to select between PeerRecord and SignedPeerRecord

AnonComm Collaboration §

• achieved:
  • Continued discussion and meetings with the AnonComm team.
  • Partial Groth16 proof generation for RLN and integration into zerokit.
  • Started drafting an approach for logos-storage anonymous download using the mix protocol.
