There are currently over 200k known zombie channels

Meanwhile, there is only about 40k active/open channels

LN has successfully reduced the BTC supply by giving noobs a new way to burn their sats.

Sure. And it's only a matter of time until Satoshi's stack gets spent too

If you are inexperienced enough to create a zombie channel in the first place, it is unlikely you also have a watchtower that will rescue your funds. Every day that a zombie remains a zombie is more evidence that it is likely burned.

Only two types of attacks.

(i) The first is a zombie attack, where a set of k nodes become unresponsive with the goal of locking the funds of many channels for a period of time longer than what the LN protocol dictates.

(ii) The second is a mass double-spend attack, where a set of k nodes attempt to steal funds by submitting many closing transactions that settle channels using expired protocol states; this causes many honest nodes to have to quickly respond by submitting invalidating transactions.

⚡️ Lightning Network is the best way.
