29. IPFS Routing Interface
    ● FindPeer (node NodeID)
    ● SetValue (key []bytes, value []bytes)
    ● GetValue (key []bytes)
    ● ProvideValue( key Multihash)
    ● FindValuePeers (key Multihash, min int)
    

    View Slide

30. Incentivization
    ● Must incentivize nodes to seed when they do not need anything
    in particular, as they might have the blocks others want
    ● Moreover, leeches must be protected against
    ● The technique be effective with and resistant to other, unknown
    strategies
    ● Leniency to trusted peers
    ● IPFS uses a simple credit system called BitSwap

    View Slide

32. The BitSwap Protocol
    ● provides resistance to attackers who would create lots of new
    nodes (Sybil attacks)
    ● protects previously successful trade relationships, even if one
    of the nodes is temporarily unable to provide value
    ● eventually chokes relationships that have deteriorated until
    they improve.

33. The BitSwap Protocol Interface
    ● Peer.open (NodeId, Ledger).
    ● Peer.send_want_list (WantList)
    ● Peer.send_block (Block)
    ● Peer.close (Bool)
