This may be a new attack tactic. By flooding the TX pool with large transactions they are trying to artificially jack up TX costs since the spam attack did not work.

As usual Monero will learn from this and improve. 👍 It is best to go through all this while Monero is still not a top world currency.

    Wow. Is there an analysis or write-up on these attacks?

      @Rucknium taking the lead on analysis here.

      check the paper he wrote re: the first wave on his git here

      https://github.com/Rucknium/misc-research/blob/main/Monero-Black-Marble-Flood/pdf/monero-black-marble-flood.pdf

      then on this wave - fat input transactions filling blocks on XMR chain :

      Thanks for mentioning my paper. It analyzed the privacy impact of an adversary owning many outputs. The transactions that are congesting the mempool/txpool now have many inputs. There may be a privacy impact of large many-input txs, but I don’t have a clear idea of what it would be, and it’s not the same as a standard black marble flood.
