My fear with LN is rather the opposite: that propagating "waves of panic" will overwhelm the block chain with transactions, because the amount of transactions pending on the LN network can in principle be orders of magnitude larger than what a block chain can handle (that's its main idea !).  So if a block chain can handle, say, 100 000 transactions per hour, and the LN network has 10 million transactions pending in 10 minutes, and there's a panic wave going through the network, those 10 million transactions will need to go on-chain which will create a backlog of 100 hours, often passing the safety time limit of regularisation, and huge opportunities to scam.

And also what would happen in this scenario if the locks on the main chain expire before the tx from LN can be pushed back to the main chain, it would be a bit like double spending issue no ?


@IadixDev,
Nice,  you see the problems with LN also.  Smiley

Improper Timelocks
Participants must choose timelocks with sucient amounts of time.  If insuf-
 cient time is given, it is possible that timelocked transactions believed to
be invalid will become valid, enabling coin theft by the counterparty.  There
is a trade-o  between longer timelocks and the time-value of money.  When
writing wallet and Lightning Network application software, it is necessary
to ensure that sucient time is given and users are able to have their trans-
actions enter into the blockchain when interacting with non-cooperative or
malicious channel counterparties

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 re-
sult  would  be  mass  spam  on  the  bitcoin  network.   The  spam  may  delay
transactions to the point where other locktimed transactions become valid

9.3    Coin Theft via Cracking
As parties must be online and using private keys to sign, there is a possibility
that, if the computer where the private keys are stored is compromised, coins
will  be  stolen  by  the  attacker.   While  there  may  be  methods  to  mitigate
the threat for the sender and the receiver, the intermediary nodes must be
online and will likely be processing the transaction automatically. For this
reason,  the  intermediary  nodes  will  be  at  risk  and  should  not  be  holding
a  substantial  amount  of  money  in  this  \hot  wallet."
   Intermediary  nodes
which have better security will likely be able to out-compete others in the
long run  and  be able to  conduct greater transaction volume due to  lower
fees.  Historically, one of the largest component of fees and interest in the
 nancial system are from various forms of counterparty risk { in Bitcoin it
is possible that the largest component in fees will be derived from security
risk premiums.
A Funding Transaction may have multiple outputs with multiple Com-
mitment Transactions, with the Funding Transaction key and some Commit-
ment Transactions keys stored oine.  It is possible to create an equivalent
of a \Checking Account" and \Savings Account" by moving funds between
outputs  from  a  Funding  Transaction,  with  the  \Savings  Account"  stored
oine and requiring additional signatures from security services.
