The problem with bitcoin is that it is hated too much. The bigger it gets the more people to have an eye on it, and more than the evil eye, the dangly rewards is what makes people think that they can have a bigger chunk of it if they use nonsense but creative and effective roads to taking the chunk they want to by whatsoever means.
Among a lot of ways to do so here is another: The dust attack.
The people within the developer community does it, mostly it is an inside job. Clogging the main net, a huge amount of transactions in every single block. Legitimate attack technique. Slow things down, because transactions take days not seconds.
Dust refers to the creation of minuscule transactions that an adversary may use to either ‘spam’ the Bitcoin network and take up block space, or to pepper certain addresses with tiny UTXOs in order to attempt to deanonymise users that go on to transact with them.
This drives a major block agenda into town, although we are unsure about why people resort to this and why certain entities enjoy doing it when by all means they are too close to home for such damage.
This may mean people sending 0.00001 bitcoin to each other back and forth, taking the same amount of time, but a longer chain than without it and a greater unnecessary burden to validate the micro-transactions. Bitcoin is pay-to-play, though actors spamming the network are a nuisance to everyone else, in that ‘honest’ participants are required to pay higher fees to avoid delays in having their transactions included in a block.
The big blocks can be forked off and if this is not threat enough then these ways to clog the network and meanwhile do random shit with the currency through anon ways is another way to ridicule the chain for what it means to us.
Indeed, coin control is perhaps the most effective way to deal with this attack, allowing the recipient to simply ignore received dust altogether so as not to risk compromising their privacy. It’s less of a systemic issue and more of a user awareness situation. The attack, however, is less of a pressing issue and more of a minor problem. Miners prioritize transactions that offer higher fees making the dust attacks cumbersome.
