So as I understand it, new transactions are new tips of the tangle, and older transactions are more and more unlikely to be picked.

At what point are illegal or unconfirmed transactions removed from the full node database?

  • What part of the explanation in the whitepaper is unclear? – Helmar Dec 13 '17 at 13:06
  • @Helmar if you will answer with a link to the relevant part of the whitepaper and a summary I will accept it as the answer – w00t Dec 13 '17 at 13:39
  • I'm afraid that your question is currently not precise enough to point to a specific point in the whitepaper or the reference implementation documentation which is a more likely source for full node information. – Helmar Dec 13 '17 at 13:47
  • @Helmar feel free to edit the question to make it more precise? – w00t Dec 13 '17 at 14:10

They will get removed (together with the confirmed transactions) at the next snapshot.

Permanodes will keep them forever (if they have ever seen them; it is not guaranteed for unconfirmed transactions that every node will eventually see them)
