29. IPFS Routing Interface • FindPeer (node NodeID) • SetValue (key []bytes, value []bytes) • GetValue (key []bytes) • ProvideValue( key Multihash) • FindValuePeers (key Multihash, min int)
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
31. The BitSwap Protocol Source: https://github.com/ipfs/papers/raw/master/ipfs-cap2pfs/ipfs-p2p-file-system.pdf (IPFS paper)
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)
