Who here has interpreted the SC paper to mean that you can get your BTC back from scBTC in the case of a SC failure?
I don't interpret it that way.
Before you can get your BTC back, you've got to perform burn transaction on the sidechain.
So if the sidechain ceases to function entirely, you have no way to generate the SPV proof that lets you claim your BTC.
Atomic swaps allow transfer to happen without waiting on the peg... a result of this means that a single 2wp transfer can basically exit all the people at once.
It does effectively mean that a sidechain abandoned by miners may end up costing more in transaction fees to exit than you'd like. The situation is much brighter than being left with altcoins no one wants, and also ignores the possible (likely?) existance of altruistic miners that continue to mine along just because.
But if some implementation of SC (I do not think SC as idea) become scam or there is a bug then bitcoins may be lost.
So in your opinion, does this mean everyone can get their BTC back in the event of a SC failure with just a larger tx fee?
