Speaking of technical discussion, Dash's privacy scheme is being (unfavorably) compared to Cryptonote.

The discussion is being held on Monero's StackExchange, because Dash by a wide margin failed to qualify for StackExchange (yet).

PrivateSend does have a potentially serious flaw.

Each coinjoin requires a server to facilitate the mixing. This requires users to trust that the server is not recording details on where each user's outputs are ending up. Dash attempts to mitigate this risk by using what they call "masternodes". Masternodes are the servers which coordinate PrivateSend. These masternodes require a deposit of 1000 Dash to run. In theory, this collateral prevents someone from creating an arbitrary number of nodes for the purpose of recording coinjoin details.

Does this really mitigate the risk of coinjoin details being recorded, enabling transactions to be traced? Not reliably. The reality is that the majority of masternodes are hosted by a small number of VPS providers. These VPS providers could easily record the transactions being facilitated by any masternode that they host.

Please respond here or on SE if you have any substantive input to make on this important issue (price comparison/speculation does not count).

the vps providers could record transactions but it would not do them any good. you need to control or have access to ~90% of the mn or transactions to deanonymize ~1% of all transactions. since these vps providers are different and spread all over the world no one entity or government has access or legal jurisdiction to that info. somewhere there is a chart showing the exact mathematical probabilities. i'll try to find it or maybe someone can post it, i think tante has the info.

ICEBREAKER, buddy, I still need your help. Please de-anonymize this transaction that was obscured by the "flawed CoinJoin implementation" that has "not been peer-reviewed" and help me to figure out the source address of these funds! The good news is that it only went through four rounds of this "DarkSend," so it will be orders of magnitude easier to figure out than if it had been through all eight. Thank goodness for small miracles!

Please help me figure this out! It's URGENT!!!

Dash De-anonymization Contest

Icebreaker and other trolleros: I have donated $1 to Monero's development team. I sent 0.25 Dash (TX ID: 59d51690d4b56ddbf1e393fa8d3a49bcfc3247f270f36be3b6ee411802666cba-000) to shapeshift.io, which converted it to Bitcoin and sent it to the official Monero donation address listed at https://getmonero.org/getting-started/donate/.

I challenge you to de-anonymize this transaction. To make it just a little easier, I only used four rounds of Darksend, so it's exponentially less private than it would be with the maximum eight rounds.

Please tell me what address this transaction originated from.

Cheers!
