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

Slide 30

Slide 30 text

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

Slide 31

Slide 31 text

The BitSwap Protocol Source: https://github.com/ipfs/papers/raw/master/ipfs-cap2pfs/ipfs-p2p-file-system.pdf (IPFS paper)

Slide 32

Slide 32 text

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.

Slide 33

Slide 33 text

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