For some reason the embedded images don't seem to load. Here is the same images as links: Historical unspent output count Transactions per day Coins generated per day Edit: It seems that the embedded images are not loading because it takes a little bit too long to generate them and the image...

Update Added cumulative data to the neo4j database Added nodes with 'BlockChainTotals' label. For each of these nodes there exists a block with the same height and time properties BlockChainTotals height time tx_count input_count output_count total_block_size total_transaction_size...

Privatesend fee is 0.001 dash and it is charged randomly about every 10 mixing sessions I think. Dash wallet shows only 2 decimal digits by default. In reality your balance is probably very close to 0.35. You can change the number of decimal digits displayed in Settings -> Options -> Display...

Looks like the outputs have now been spent :)

I've noticed that querying certain stuff from the database is quite slow and the queries can timeout (over 60sec). As a result I've decided to add hourly data points that represent the total value of things since the first block. It would contain for example the following things: timestamp...

Regarding the last update I made some example queries that might help anyone to get started creating their own: Average block size over time Total number of privatesend transactions and total number of regular transactions after block 600000 Total number of each denomination mixing...

Update Check out https://dashradar.com/cypher. It's related to my previous post where I was talking about neo4j and cypher queries. In that page you can write (or use someone else's) cypher queries and instantly display the results in a line, bar or pie chart. You can share your query with...

Update Added sound effects to live mode as suggested by @solarguy Sound can be disabled in settings Added "max transactions in live mode" to settings to prevent lag when running live mode for a long time Oldest transactions are removed when this limit is reached Added more stuff to...

Actually I'm not so much interested in how likely it would work but more interested in understanding why it works. For example: would it select A2 as the only possible source address like I understood it. If it would then what's the reasoning to exclude for example the combination of A1 and A3?

They used 2 rounds which is the default number in the dash wallet and probably a significant amount of dash users use. However I don't know if they tracked only 2 rounds because an outside blockchain observer couldn't know the number of rounds used.

Quote form the paper: " Experimental setup. To perform this attack, we used shapeshift.io (an online service for conversion between cryptocurrencies) to convert Bitcoin into Dash, which we withdrew into a single address. We used the default Dash wallet to mix 0.55 Dash using the default...

Quote from the blockski paper: "The intuition behind the attack is that outputs mixed in different transactions are often spent together. Thus, when these coins are spent together, we trace each one back to a (potentially large) set of possible address clusters and examine the intersection of...

Haven't had much time to develop this but here is something that you can play with if you want: http://dashradar.com:7474/browser/. With that you can query the dash blockchain using the neo4j cypher query language. Here is some example queries that you can try executing: Count the number of...

You don't need to trust the host with your private keys. All they could scam is the hosting fee. You are probably right that you can't run a masternode over tor anymore but it used to be possible.

I don't understand this example. Also I don't see how is this a problem if you are running masternodes. Masternodes currently earn ~0.2 dash/day according to dashninja. That's 20 times the smallest denomination. And masternodes require 1000 dash so there is like 0.001% that you can't spend...

@UdjinM6 was this behavior changed in this commit: https://github.com/dashpay/dash/commit/f98fe6a2087b2c4e90dc2726837600eea0166caf I don't really understand the code too well but it seems to match pretty well with latest date where I have found this kind of transactions (aug 22 2015).

I'm working on my visualization/analysis tool and stumbled upon these transactions that my tool currently does no detect as potential mixing transactions because they use multiple different denominations...

I could be wrong but I think you could make 3 separate transactions: A->D, B->D and C->D. Then you could mix on D assuming that you have at least 0.01 and there is no solid proof that A, B and C are controlled by the same person.

Mixing has fees but I don't think it should be that expensive. Do you have more dash available for regular transaction? If so then I think the wallet might have reserved some of the funds for privatesend fees but didn't need to pay them. There is a random change of having to pay a fee for each...

I don't know why such a thing would happen. Maybe a bug in mining software or a misconfigured masternode? I found them after I imported the whole dash blockchain to a neo4j graph database. After reading the Script page in bitcoin wiki I decided to search for outputs anyone can spend and found...
