Is there a inherent cost vulnerability in Lightning Networks? Users will still lose money without error
Peter R Rizun, chief scientist at Bitcoin Unlimited, recently spoke with a shocking view of the second-tier protocol lightning network proposed to solve the problem of bitcoin scalability. Peter R Rizun claims that Lightning Network users have inherent cost vulnerabilities that will lose all funds without doing anything wrong.
Lightning Networks is Bitcoin's second-tier solution that allows users to make payments under the chain, ensuring faster bitcoin transactions and lower costs. Lightning networks rely on the underlying technology (ie, the Bitcoin blockchain), but primarily support the need for smaller transactions. Users do not need to record payments on the blockchain to make payments until they are finally settled. In addition, Lightning Networks may also play the role of a multi-currency routing network in the future.
However, Peter R Rizun believes that in the high-frequency and unstable environment of the first layer of Bitcoin, Lightning Network users will lose all their money without any faults, because when the demand for blockchain space surges, the bit The block size of the currency limits the high and unstable cost.
In this regard, Cornell University professor Emin Gur Sirer said:
“The bitcoin block designed by Nakamoto has not considered most of the filling, and the developers have not designed a stable and predictable charging mechanism.”
In addition, a user from the Reddit forum "Jungans" believes that the "lost money" situation of the lightning network is not the same as the chain of funds scattered on some unpaid transaction output (UTXO). In this regard, Peter R Rizun clarified that the lightning network problem and the unpaid transaction output are two completely different situations, and made a detailed explanation:
Imagine when you open a lightning network channel where you have a $50 balance. Maybe you will pay some fees to the channel partner, assuming that the fee is $25, then you have $25 and he has $25. But then the channel cost increased from 0 to $10, so you have to transfer $10 from your only $25 to the "fee bucket" so you only have $15. Next, if the cost goes up to $20, you need to take another $10 from your balance and transfer it to the expense bucket, so now your balance is only $5.
But the cost is rising, and your channel partners are very worried, and soon you won't have enough account balance to pay for it, and channel partners can't claim to get the $25 they deserve. So, if your channel balance has no money, he will forcefully close the channel. This will result in a result that all your balance will go into the expense bucket, then the channel will be closed, and then $25 will be returned to your channel partner, but at this point you have nothing to gain, your channel partner is now going to do The wait is for the cost to drop.
Maybe after a week, the cost will drop to $0, but at this point you have already spent $25, and your channel partner spends $0. In other words, you have not done anything wrong during this period, but you have lost money "inexplicably". Recently, the lightning network caused great concern in the community due to the upcoming “extinguished” lightning torch activity. The channel capacity also reached a record high of 5 million US dollars. In addition, the lightning network has covered 131 countries around the world.
