Nano network is slowing to a crawl after a multi-week attack.
Over the past week, a spammer has been sending tens of millions of tiny transactions to new wallets. This has been bloating the Nano blockchain which has been putting stress on the validators.
They were handling it fairly well, until today. The attacker ramped up his attack and averaged 60 TPS, with bursts up to 500 TPS. This overloaded many of the nodes and they have started desyncing. Confirmation time is over 5.5 seconds and climbing fast. Before the attack, it was around 0.2 seconds. Edit: Seems like a lot of transactions aren't going through at all.
Its unfortunate for the network, but fascinating to watch from a data perspective. I linked some resources below.
