what would stop a malicious cluster of spamming xrb by making billions of empty wallets that may clog the worldwide size of the blockchain?

XRB is pretty attention-grabbing, however as others have mentioned they need heaps of labor to try and do to prove the network will be trusty. It uses delegated proof of stake to vote on that transactions square measure valid. i am undecided however nice a technique this can be our however simply it might be gamed. They additionally would like a far more practical way to stop ddos attacks wherever somebody might send immense numbers of transactions back and forth. at once there's a little proof of labor needed by every dealing to forestall this, however several are skeptical it'll be enough. The developer says they may increase the problem (so a lot of for "instant" transactions) or scrutinize another methodology of spam hindrance.

The other major downside is information measure. They advertise XRB having the ability to handle 7000 transactions per second, however this might lead to one thing like seven MB/s of information measure needed by each single node. there's no method they will all maintain therewith. A additional realistic estimate I've seen is around one hundred tps. at once XRB is lucky to try and do 7000 transactions in an exceedingly single day, therefore these crazy estimates of output square measure fully on trial.
