I don't understand some of the details of how
liquidity stack works in Haircomb cryptocurrency. In the documentation it says that a stack is a
construct, and "Constructs are stored off-chain in your wallet".
Is the stack object supposed to be created on the payer's or the payee's machine?
What happens when I send funds to a multipay stack which was created on another machine which is currently offline? Does it mean that all the payments that are defined by the stack will not happen until that machine is back online?
I have also seen in a discussion:
"Only if the amount at the liquidity stack input reaches the stack internal threshold, the observer considers that liquidity stack as triggered. After triggering, the threshold amount is moved to stack output, and a stack transaction connects the liquidity stack to liquidity stack change. If users didn't honor this rule then Haircomb couldn't function as a currency. That's why all user do honor the rule."
I didn't understand some details in this explanation.
How is the stack able to implement the transfer of the input funds to two addresses? I thought that in Haircomb we can only have no more than one directed edge coming out of an address.
I did not understand who "the observer" who decides when the stack should trigger is, and I did not understand the statement "all users do honor the rule." Does it mean that all users can see that the stack splits the input correctly? Does it not require that they could see the input amount (which should be hidden from most users)?
Or does it only refer to the user who owns the stack object? If so, why should we all trust him?
