Also, I would have thought recent events would leave people a little wary of attempting to create artificial pegs algorithmically. I think I'd feel more comfortable if no one managed to claim the reward for that one.
What's the benefit of pegging your Lightning balance to USD? And how exactly is this supposed to work? Like, creating 1 L-USD for each 3,000 Lightning sats? Doesn't make any sense. Bitcoin is free money; a currency on its own. And so is USD. Whoever wants to switch, utilize trading.
all 3 challenges are not for fangirls to claim like some bitcoin puzzles announced over the years. its for devs to integrate LN functionality into wallets with different features AKA dev bounties, AKA sponsored features, AKA commission for developers.
the idea presumably.. is obvious
allow atomic swap between lets call it mcent and msat. so that people can do decentralised exchanging of pegged fiat to pegged bitcoin, off chain and off bank
everyone (apart from certain people who pretend they dont know) understands that LN is its own network that can bridge to many chains.
meaning the challenge in question is looking for Ln devs to make a USD stable coin segwit compatible and thus lock compliant to easily then allow a gateway into LN to then have it where LN channels can be cent/micro-cent based balance.
or any other way to get a USD stable coin to lock/bridge to LN
its not about converting a litecoin pegged 'lit' or a bitcoin pegged 'msat' to be worth some USD amount. its about having USD stablecoin locks/pegs to something like mcent balance in LN
