Flood & Loot: A Systemic Attack On The Lightning Network

„9.2 Forced Expiration Spam
Forced expiration of many transactions may be the greatest systemic risk
when using the Lightning Network. If a malicious participant creates many
channels and forces them all to expire at once, these may overwhelm block
data capacity, forcing expiration and broadcast to the blockchain. The result would be mass spam on the bitcoin network. The spam may delay
transactions to the point where other locktimed transactions become valid.
This may be mitigated by permitting one transaction replacement on
all pending transactions. Anti-spam can be used by permitting only one
transaction replacement of a higher sequence number by the inverse of an
even or odd number. […]
Additionally, one may attempt to steal HTLC transactions by forcing
a timeout transaction to go through when it should not. This can be easily
mitigated by having each transfer inside the channel be lower than the total
transaction fees used. […]“

Beeinflusst das nun die Skalierbarkeit?
Theoretisch ja, weil niemand große Channels öffnen wird und ob die Kleinen dann genügen weiß man ja nicht.
