That’s a blockchain thing. They can fork, but they aren’t going to do that if I lose $150 in Libra. If they can single reverse transactions, there’s really no point to it being a blockchain. If it’s refundable then they are just paying for the crime itself out of their own pockets. They will still need a human layer to verify theft has occurred and it isn’t a fraudulent claim of theft where just I stole from myself.
They don't need to form the blockchain to reverse a transaction. Since they control redemption and minting, they can simply refuse to redeem from the "losing" party and mint new units to compensate the "winning" party. >They will still need a human layer to verify theft has occurred and it isn’t a fraudulent claim of theft where just I stole from myself Or have something similar to credit cards where you're forced in…
They can mint, and that's not a direct debit from Facebook's wallet, but it would devalue the currency ever so slightly.
But that raises the question of 'How much needs to be stolen before I activate the minting process?' If they mint for low theft values, then I can find a way to steal from myself and that's probably a decent amount of passive income. If they only mint for high theft values, then that only helps rich people who suffer the least from theft (unless they cram all of their life savings into it).
All of this depends on how Facebook works with law enforcement to manage the criminal parts of Libra. Working closely with them means we move closer to a corporate state. Working loosely with them means Libra is more vulnerable.
