Re: BYTEBALL: Totally new consensus algorithm + private untraceable payments
The detection seems to be done after the address is linked, that's whay I raised this concern:
Or am I missing something and there's no concern to have in this regard? i.e. you/the bot will be able to detect such an address and remove it before the snapshot.
Okay, given the fact that the old link is removed (fast enough), my question is no longer relevant. It is just that I saw one address linked to two bytaball addresses, so I don't know how fast the bot detects that and removes the link. I assume the bot will be able to remove redundant links done on December 24 at 23:59:59 UTC before the snapshot(?).
Why would lowering the micropayment be riskier than with the current micropayments? (because they would be easily spotted?)
Yes in most standard cases it can't, but exchanges can sign a message with an address holding funds which are not really theirs, can't they?
Thx.

Isn't there a risk that someone links an exchange address on December 24 23:59:59 UTC and gets included in the snapshot? Meaning would it be costly to try and detect exchange addresses before adding them?

If you link the same Bitcoin address to another Byteball address, the old link is currently removed. We could blacklist such Bitcoin addresses altogether (i.e. if different Byteball addresses try to link to them) but this might negatively affect blockchain.info users who have constant address by default as far as I know (correct me if I'm wrong).

Further lowering of micropayment amount is risky because it opens an attack vector: an attacker might see your microtransaction on the blockchain and repeat it exactly from his address (i.e. send the same amount to the same our address) trying to link his address and trick you to send all your bitcoins to his address. Most users will notice, and the attacker just loses his bitcoins, but if the amounts are too small, the attack might pay off.

Yes, signed message cannot be abused easily.
