But a lot of the masternode supporters say that ring signature blockchains will become so bloated that they'll never be useful. Can someone calculate how bloated they would be? Like if Bytecoin or Monero had the same transaction volume as Bitcoin, how much larger would the chain be?
This is just pure speculation and misunderstanding. That's like saying that Bitcoin can't scale to high transaction count in the future.
Bitcoin can't handle a massive amount of transactions at the moment but this can easily be solved increasing the max transaction size.
So when the time comes (if it ever does) I guess the same can be done for Bytecoin.
The "bloat" is always relative, considering that you have untraceable and unlinkable transactions that work NOW, how useful is that ?
Also, see this :
https://forum.cryptonote.org/viewtopic.php?f=2&t=10I completely agree.
If you said you can have bitcoin, but anonymous transactions with 5 times the bloat, would you say yes?
But they all want centralised MasterNodes so they can be spied on, because bloat is bad.
