Title: is it Dusting ?
Post by: Chandu141 on November 06, 2020, 10:47:15 AM
I came to notice this below transaction and wondering what exactly its purpose ? 

https://www.blockchain.com/btc/tx/4ff35188b4cd5649c1578b8256b49fbb68e92006f81d83a6f224d96264fe9c31 (https://www.blockchain.com/btc/tx/4ff35188b4cd5649c1578b8256b49fbb68e92006f81d83a6f224d96264fe9c31)

It seems the first couple of outputs are actually some sort of spam, leading to https: [slash] [slash] memo [dot] sv [slash] topic [slash] hmwyda

Maybe the dust is meanth for the receivers to check the transaction funding their address and following the spam link?

Someone is spamming the bitcoin network trying to spread a message a cross probably by one of the shills of the BSV scam coin. If you look at the addresses closely, there is an encoded message
Code:
Lets use fuLL power of anonymity
See memo dot sv topic hmwyda

If you follow the message, it leads to this link
Code:
memo.sv/topic/hmwyda
Basically, it's all just nonsense.

This is doesn't look like a dusting attack but a promotion of some way to create unowned bitcoin addresses.
I just digged into the information provided and got the below from the memo.sv website .

Quote
hmwyda - how much would you donate anonymously

it's easy to create unowned bitcoin address from arbitrary text:

https://duckduckgo.com/?q=ripemd160+send+1%25+how+much+you+would+donate+for...
3508335e35092024773daa3bf333d82d70323df2
paste to the step 3 on https://gobittest.appspot.com/Address
address is 15qQdxbij3hXN4wghYnenHmfb9pyDatzY6


Looks like someone is spamming the bitcoin network while promoting this site.
I wonder what good does it do to anybody ? They are just wasting money while spamming the bitcoin network.

A lot depends on how many transactions this causes.

I did a long thread that is a sticky that explains what a large pool such as antpool can do to increase transaction fees.

edit : thread link. https://bitcointalk.org/index.php?topic=2634505.msg26809430#msg26809430


The long and short of it is a large pool can whitelist little bullshit transactions with tiny fees to flood the network memory pool.  

This causes normal users to have to spend 100 to 300 sats a byte to get our transactions to move.

So I spend 1 btc a day making bullshit transactions
I am antpool I make 20 blocks a day.

These blocks average 1.0 btc in fees due to my flooding the network’s memory pool.

that is 20 btc and I spent 1 btc to do it.

that is a gain of 19 btc.

If I did none of these fees may have been .1 btc a block or 2 btc at no cost.

so 20 btc at a cost of 1 btc
vs 2 btc at a cost of 0 btc

it is obvious flooding the network makes sense.

Lets say when I pay coins back to miners I give 1/2 the fees to them

my flood the memory pool way is 20/2 = 10 - 1 = 9 coins profit.

my do nothing is 2/1 = 1 coin profit.

I am not sure the intention of the guy doing this promo is what I said , but if it looks like a duck ,quacks like a duck and walks like a duck more often then not it is a duck.

Looking at one of the addresses (1Lets1xxxx1use1xxxxxxxxxxxy2EaMkJ (https://blockchair.com/bitcoin/address/1Lets1xxxx1use1xxxxxxxxxxxy2EaMkJ)) shows it has received 1103 transactions in 3 months. The transaction fees aren't even low, it's easily $40-$60 per transaction now. I only checked a few, but this must add up to tens of thousands of dollars in fees alone, plus the amounts send to Bitcoin addresses.

What's even weirder is that the same thing is happening on the BSV chain (https://blockchair.com/bitcoin-sv/address/1Lets1xxxx1use1xxxxxxxxxxxy2EaMkJ).

So then it does not look like a duck if fees are that high.

While the intention isn't to perform dusting attack, but it doesn't attack the change the fact that it could compromise user's privacy if they spend the dust altogether with another input.

So then it does not look like a duck if fees are that high.

It's still interesting theory, although it only makes sense to do it for short time before it affect bitcoin reputation due to high fees.

I had a lot of tx evidence back in 2017. I am pretty sure it was done back then.

The year not so sure.  The dynamics are different.  A lot of people can get some BTC via PayPal so it could just be a lot are buying some coin which is why fees are up. Last diff epoch had the largest drop of hash ever in terms of th. So it certainly helped back the memory pool up.

As I type viabtc  is paying 121% of a block which means high fees at the moment. Last week they paid as high as 132% so this diff jump more block speed is happening cutting fees down some what.

https://www.blockchain.com/explorer?utm_campaign=dcomnav_explorer

655822 0.37 in fees
655821 0.79 in fees
655820 0.40 in fees
655819 0.60 in fees
655818 2.15 in fees
655817 0.62 in fees.

last jump we were  pulling over 2 coins a block in fees. but we were doing   144 x .84 = 121 blocks a day vs 144. this jump we are doing 144 x 1.035 =149 blocks a day

so 121 vs 149 results in 2.1 btc in fees vs .7 btc in fees each block.. It takes a lot of time and effort to analyze fee patterns to see if there is a flood of 0.00001 deposits with 0.00000300 fees.  It did happen back in 2017 we had times there were 6.0 in fees for some blocks. We average 3 coins a block for a stretch.

Seems some of the targets are also wallets held by government agencies.
For example bc1qa5wkgaew2dkv56kfvj49j0av5nml45x9ek9hz6 (https://blockchair.com/bitcoin/address/bc1qa5wkgaew2dkv56kfvj49j0av5nml45x9ek9hz6) , allegedly the address of the US govermnet that seized the 69,369 bitcoins related to SilkRoad also got "dusted" with 547 sats in a "Lets use full power of anonimity..." transaction (https://blockchair.com/bitcoin/transaction/f7aae4c37c93a0b09361935a7756088fe9a515d20c6bf81766a7d2bbeb1561a2).

Guess they target high profile and controversial addresses. Something like blockchain SEO, so they get more views I assume

I'm more surprised they also target addresses with a very low balance. This address (https://blockchair.com/bitcoin/address/37V6hxedN3R85nzavo3x3ZcimRqZyGZoBx) was first used 8 days ago, and has received only 0.00500547 BTC in total. None of this makes much sense :P
