First, this gives the Dash community ammunition to effectively respond to challenges that Dash isn't private enough. We can publicly challenge anyone who thinks PrivateSend is weak to try to claim the prize by breaking the anonymity.

Secondly, this is designed to be a huge PR event where we can promote Dash generally by publicly organizing, announcing and discussing the ongoing status and conclusion of the Contest.

an unspecified quantity of Dash is in a wallet in address(es) A

the dash is mixed using an unspecified number of PrivateSend rounds

0.1 Dash is sent in a PrivateSend transaction to address B

address B is given to the public with a challenge to determine the address(es) A where it originated from before PrivateSend mixing began

Preference will be given to judges with substantial social media presence

Involving members of the other crypto communities as judges will gain Dash exposure to a wide crypto audience.

Offering a contest with a significant prize demonstrates to all how the Dash treasury system can do things that other coins can't do

Offering a prize that increases each quarter makes the contest more newsworthy with fresh opportunities to discuss the new larger contest prize.

When promoting the contest we now have an excuse to go into "home forums" of other coins and gently plug the Dash contest

This gives Dash Force News and everyone else covering the crypto space something interesting to talk about to help increase Dash awareness

The contest improves confidence in the PrivateSend technology in a way that is more meaningful than simply just claiming "ours is the best."

Charitable donations will be paid in Dash expanding Dash awareness in the non-profit community.

Rules for claiming Contest Prize:

enter by sending an email to PrivateSendContest@protonmail.com including "I won!" in the subject line. Communications should include an English translation if necessary. The size of the prize will be determined by the prize in effect when the entry email is received. Entries should include their choice of cryptocurrency and the payment address to receive any prize winnings. The conversion rate between the nominal USD prize and the cryptocurrency of the winner's choice to receive payment will be locked at the time the winning entry email is received by the contest administrator and at their sole discretion. Winner's choice of cryptocurrency must be among those supported by Shapeshift.io.

correctly identify the originating address(es) of the PrivateSend transaction before the mixing started

reveal the method by which the PrivateSend transaction was de-anonymized in sufficient detail to convince at least 2 of the 3 judges that the anonymity was effectively compromised. simply making a correct address guess will not be sufficient to claim the prize the method used to de-anonymize the transaction must tie the origin and destination addresses together either directly or by greater than a 50% chance if using probabilistic methods the DASH core team will have a least 14 days to review any de-anonymization method and provide a technical opinion to contest judges any discovered PrivateSend vulnerability must be confidentially disclosed according to Responsible Disclosureï»¿ principles in order to receive the contest prize.



contest entrants must supply an email address in case any questions regarding the de-anonymization methodology arise. Email addresses will not be used for any other purpose and will be destroyed following the conclusion of the contest.

If the contest prize is won it will be paid within 60 days.

entries not meeting the criteria above will be considered Spam and deleted

The contest announcement to the public will contain a cryptographic signature of a message which reveals the origination of the PrivateSend transaction funds (the solution to the contest). In the event of a dispute regarding the correct solution to the contest the signature may be used to verify the solution.

No member of the Dash core team or anyone involved with the contest in any way, including the judges may claim the prize.

If at least 2 of the 3 judges agree that the contest has been won following 14 days technical consultation with the Dash core team, judges agree that Dash will make the announcement regarding the conclusion of the program taking Responsible Disclosure principles into consideration.

It would obviously be an embarrassment if someone actually won this contest by de-anonymizing Dash. Need the core team to ensure that all known PrivateSend vulnerabilities have been addressed. This risk can be mitigated by correcting a discovered vulnerability and then launching a fresh contest with a doubled prize.

It is possible that a contest judge or other person may leak the origination address(es) or otherwise have the address(es) exposed due to security problems. This isn't really a concern since claiming the prize requires demonstrating how the source and destination addresses are linked.

Escrow holder:

Dash has a robust, protocol level coin mixing service called PrivateSend, but it is frequently dismissed as inadequate by those favoring other coins such as Monero, Zcash and others.The purpose of this program is to create a Contest and Public Relations event to challenge people to determine where coins in a PrivateSend transaction originated from. The purpose of this is two fold:The Contest will offer a prize worth up to $100,000 USD, paid in the winner's choice of cryptocurrency, to someone who can successfully determine the originating address of a small quantity of DASH in an address given out to the public.Example:â€‹The contest will begin with a prize of $25,000 and then increase by $25,000 each quarter until a maximum prize of $100,000 is reached as follows:Start of Contest to 3 Months: $25,0003 to 6 months: $50,0006 to 9 months: $75,0009 to 12 months: $100,000To help keep the contest impartial, I will arrange for a 3 person panel of prominent members of the crypto community to serve as contest judges. These people will not be generally connected to the Dash community. I will target members of the Bitcoin community to be judges to elevate Dash awareness among Bitcoin users.As an incentive, at the conclusion of the contest the judges will each receive a donation of 100 Dash to be paid to the charity of their choice. The charitable donations will be made whether the contest prize is claimed or not.This is intended to be a big PR event and not just a simple bug bounty.To claim the contest prize, the winner must do the following:In the event of a dispute regarding the contest Dash will make the final determination of the outcome. Contestants agree to hold contest judges and members of the Dash community harmless. Dash reserves the right to modify or terminate the contest at any time without notice.I will work closely with the Dash core team to coordinate efforts. I will also coordinate PR or provide content to Dash Force News or others as appropriate. @mastermined Upon approval of this proposal the administrator of Dash.org shall create a contest landing page at Dash.org for promotion and execution of the proposal. PO will provide the content for the landing page.The contest will run for a period of 12 months.This is a critical time in the crypto community with news about Bitcoin forks taking all of the headlines. A new fork for "Bitcoin Cash" with 8 MB blocks and a stance toward on chain scaling was recently created. Another Bitcoin fork may come in October/November.These forks more closely compete with Dash for the "digital cash" market segment so this is a good time to highlight Dash's advantages over these new Bitcoin forks and other digital cash coins. This contest helps to accomplish this by creating a PR coup to take some of the headlines back for Dash.Contest prize - will only be requested from treasury if needed to be paid to contest winner. Dash will be converted into the cryptocurrency of the winner's choice.Charitable donations - 300 Dash (100 Dash each to be paid to the charity of the judges respective choice.)Program promotional material development, judge recruitment, communications and program management - 80 DashEscrow fee - 10 DashProposal fee reimbursement - 5 DashTotal Request: 395 Dash98.75 Dash per month for 4 months - 395 Dash total.

I've been into crypto about 2 years and am a reformed Bitcoin maximalist. I got bitten by the DASH bug recently because of all it's great features and all of the governance problems I see with Bitcoin. I bought my first DASH a few months ago.I'm writing under a new handle DashDude, but for full transparency my name is Steve Dussault. I'm a professional working as a Sr. Product Manager in heavy industry with many years of blue chip company experience. I have extensive experience introducing new high-tech products worldwide and working to increase their market share and profitability.If the price of Dash is above $284 when the contest launches, I will also research and develop an infographic to highlight Dash's competitive position against Litecoin - something many have requested from me already. I will also translate it into 9 other languages in addition to English for a total of 10 infographics.For reference, please see this infographic I did previously called the "10 Stupid Things People Say About Dash" ï»¿.Thanks for your consideration and your votes!Steve
