argh Friendly Ghost != FFG :/ so confused by the names
@nicksavers@mratsim thx for your kind help :-)
Hi! I'm quite new to Casper and i'm doing some FFG research now. May I ask is there a way for me to customise my casper contract if I use Harmony docker to run a testnet? let's say, I want to change the transaction rate or block percentage. Because so far from what I ran i realise a lot of things are pre-defined.
Thank you very much
was an update recently pushed to rinkeby testnet? my solidity code doesnt work the way it use to 2 weeks ago
<vbuterin> Sorry which Casper contract are you trying to run?
<vbuterin> Are you running the pyethereum-based code from last year?
<vbuterin> If so that is outdated and no longer applies
<vbuterin> I recommend waiting 1-2 months then trying to run nodes from prysmatic, lighthouse and co
Hi guys. I wonder why the red box (evil validator is 1/3 ~ 1/2 under no 51% attack on pow) is fully safe. Isn't the box should be "Liveness failure"? It will be very helpful if you guys give any reference about it...
Are there any article's about possibly proving stake in PoS by using zero knowledge proofs? That way the particular stake doesn't get tainted.
@nicksavers what do you mean by 'tainted'?
i don't have all the details but you could imagine doing some kind of range proof (a la Bulletproofs) against the bonded stake.... however for consensus safety you probably want to be able to track every behavior down to the wei and removing that knowledge could be dicey
that is, the entire pool of bonded stakes, not just some individual validator's stake
@ralexstokes what I mean is that 'stake' can be held responsible for including transactions from sanctioned addresses making it basically impossible to sell at a regulated exchange afterward.
Any signature (tied to stake) for a block including one of these transactions.. or a block building on top of a block that contains an 'illegal' transaction could be used as proof that the stake was used for nefarious activities.
yeah... defo something to think about
you have to balance accountability w/ zero-knowledge propety
