Bitcoin was under attack! It’s the story the mainstream media won’t tell you!
Hosts Aaron van Wirdum and Sjors Provoost finally met in Utrecht again to record “Bitcoin, Explained.” In this episode, they discussed a recent attack on the Bitcoin network, where some nodes were flooding peers with fake IP addresses.
"Ti naključni ljudje, ki so se povezovali z njimi, bi poslali 500 sporočil in vsako od teh 500 sporočil bi vsebovalo 10 naslovov, ki naj bi predstavljali druga vozlišča v omrežju," je dejal Provoost. »Sporočila so bila resnična, vsebina pa neumnost. Torej bi se vozlišče povezalo z vami in poslali bi vam kup naslovov, vendar se je izkazalo, da so bili ti naslovi le kup naključnih številk.
As previously discussed in episode 13, Bitcoin nodes are connect to peers on the network through IP addresses, which they learn from their existing peers. Nodes on the network essentially share the IP addresses of other nodes.
Recently, however, some Bitcoin nodes shared large amounts of IP addresses that weren’t associated with real Bitcoin nodes at all. While this attack did not do very much damage, it did waste resources from nodes on the network. On top of that, van Wirdum and Provoost explained, the attack could offer the attacker insight into Bitcoin’s network topology by analyzing how the fake IP addresses spread through the network.
Nazadnje sta van Wirdum in Provoost razpravljala o tem, kako je bil napad rešen s hitrostjo omejevanja količine naslovov IP v skupni rabi, ki jih bo katero koli vozlišče omogočilo svojim vrstnikom. Poleg tega so razmišljali, kako pri razvoju brezplačne in odprtokodne programske opreme odpravljanje težav ni vedno tako preprosto, kot se morda zdi.
