Checked my address today, I apparently received exactly 1 satoshi from: 162RRiyg9CMZZ5FjyJbSHTLebtFCXd6KWj with the label btcsmart.net
In this transaction:
https://blockchain.info/tx/749559de62baf0ae58d1a70f34ff9c2164a61a7631a88c4ad4d7ecd749d055d2
What the heck is he trying to do, hes sending 1 satoshi to hundreds of addresses.

they are technically spamming.. multibit gets rid of those as they will probably never confirm.. i dont know what info they are after, but they are doing it for a reason..

Well, you're probably going to at least Google the company name if you don't visit it outright. Could host malware. Dumb way to advertise, otherwise... super-slimy.

I think it is actually a somewhat effective way to advertise. There was a gambling website that was sending out one satashi TXs to many addresses (thousands, if not 100s of thousands). It even made the news.

Laxotrade is sending out random TXs that are much bigger (~.0001) and there are a few threads open about them.

I am not sure how effective this kind of advertising from a cost standpoint but they are certainly getting people to look at their name at the very least.

It confirmed. How does a TX with dust outputs confirm? I though that was no longer possible.

It's possible, but there are (relatively) harsh fees to send dust. He spent BTC0.0002 to spam out BTC0.0000025 in satoshis. Hard to beat ~9-10 US cents to direct-spam 25 people, though.

I somehow was under the impression that a "gavin" (~5430 satoshi) was a protocol limit, but apparently thats wrong.

Edit: smallest amount that core allows is 0.00000546, so my memory also was wrong by a factor of 10.

Edit2: found it [1], apparently its more complicated.

I got 1 satoshi too, which is strange as I cannot send transactions smaller than 0.0001 (the fee).
Which wallet has such low fees?

It is just an ad.
After receiving a mysterious transaction to your address, some of the receivers will go to blockchain.info to search for it, and a few of them will go to that site.

BTW, you received 10 satoshi instead. Congrats for getting 10 times more lol. ;)

Transaction fees should be increased to avoid these satoshi spams.

You mean fee or dust output?

The transaction in OP pays 0.0002 BTC with a tx size of 1042 bytes, which is the standard tx fee 0.0001 btc per KB (rounding up to the nearest KB).

lol, somebody using this method again for advertise some site
it's very annoying, but this one will disappear after few times
just remember somebody use this method to promote sochi winter olympics, with address 1Sochi :D

I got that several time too, but apparently it's just an another unspent output in wallet.
it took almost a week to confirm it but at last it got confirmed.

Hate dust, sometimes you pay even more fee just to send them..

This spam can increase dramatically the size of the blockchain if it's done by several people.

yeah right, sometimes fee for bitcoin network is more higher than that dust :D
but i think 1 satoshi dust won't confirmed by network
they will vanish after period of time :)

Not this time, the transaction mentioned in OP has already had 96 confirmations right now. :)

Is it possible to remove blockchain.info tag from address?
(and remove address from bc.i tagged list)

I've recieved about 200k satoshis whom someone, no label no nothing. Maybe someone used the wrong address? :D

Probably morons trying to spam the blockchain.

Most of those dust transactions are just advertisements or someone messing with people and/or the blockchain. At least they have to pay something for such a spam, although I think that miners could be wise to just decide to ignore such transactions or let the fees grow dramatically.
You've just created a thread about this, the advertisement has worked! :)
