dust spam attack? #77

Closed paulperegud closed 7 years ago

paulperegud commented 7 years ago

Scenario is as following: a lot of small transactions is made from different accounts, blowing up size of balances array. Can this affect other funders?

I see three possibilities.

a) gas cost of creating one more entry in balances is not a constant function of size(balances).
b) gas cost is constant, but work is not constant and this operation can be used to spam network
c) no worries, ETH has withered more complicated attacks

Storage size does not influence the cost (like in b). This is Ethereum network issue, not the contract issue.
