Title: Addresses with 0.00005460 BTCs history
Post by: jovica888 on March 17, 2018, 10:08:05 PM
I know PHP so I made something like Brainwallet brute force... I made it record every address that has been used then it will monitoring all founded address because maybe they will be used again in the future.

So I founded a lot of address where 0.00005460 BTCs are received and 0.00005460 BTCs are sent. That's it. Why this amount and why so many addresses ;)

Under old dust rules 5460 was the minimum output size for standard transactions, it was later decreased to 546 satoshis due to the increase in value of BTC, although different nodes may operate under different rules.

i think it was a researcer doing tests in that pariod. The completly list of the words used was about 17k words.

How many did you find containing exactly that 5460 sats utxo?
I'm more curious about the 1 sat utxo spams tagging many addresses back in 2015 and recent 2017
in 2014 sent by 1Enjoy... (https://blockchain.info/address/1Enjoy1C4bYBr3tN4sMKxvvJDqG8NkdR4Z) and last year was by 1Sochi... (https://blockchain.info/address/1SochiWwFFySPjQoi2biVftXn8NRPCSQC)
if you have time, please monitor these 1 sat utxo... how many were sent out and spent
spending/consolidating this 1 sat costs more that its value  >:( :-X

If they're relatively recent transactions... there is a chance they could be "CounterParty" transactions (https://counterparty.io/)

Basically, CounterParty is a system for sending "tokens" that utilises the Bitcoin blockchain... It requires that you send "dust" to the person you're attempting to transfer assets/tokens to and 5460 sats was the "dust" limit for quite a while.

that reminds of the address below, if I'm not mistaken this is related to tether
https://blockchain.info/address/1Po1oWkD2LmodfkBYiAktwh76vkF93LKnh
each transaction consists of 546 sats to 1Po1oWk and 2184 sats back to sender with 1mBTC tx fee :D
I don't understand how it works but I just learned the "dust" limit is the requirement as you pointed out

i think it was a researcer doing tests in that pariod. The completly list of the words used was about 17k words.

I'm currently at
Code:
$ grep 0.00005460 analysis* | wc -l 
39915
and sitll counting

no, it was a spam attack against bitcoin network which they called "stress test"! basically at some point they tried to get others involved and try to flood the network with double spends. so they sent a ton of transactions to addresses with known private keys (which a lot of automated scripts are watching to steal their coins) and also a lot of coins to other keys which they released later: https://bitcointalk.org/index.php?action=profile;u=553487;sa=showPosts to cause a lot of traffic between nodes sending double spends. and to simply make people do the spam attack for them!

actually, they are USDT transactions.
