I'd like to host the first NCAA pool with a contestant that has a perfect entry. The amount of entries needed should be in the hundreds of billions. Here are the details as to how I am trying to make it work.

Would you participate? Way too complicated? Advice on how it could be done better? For those unfamiliar, google "Perfect NCAA Bracket" or something similar.

Goal:
* I want to make history by hosting the first pool that has a contestant enter a perfect NCAA Men's basketball bracket.
* It should easily be the largest NCAA pool in history
* Last year Warren Buffet offered $1.0 Billion for a perfect bracket, and no one made it out of the first round.
* www.perfectbracketsearch.com

Incentives and cost:
* I'm putting up 2.000 BTC as an incentive for a perfect bracket (12yoo2eYjBLoqxqGw1BCM3BJ7uox4TT4hc)
* I'm putting up an additional 1.000 BTC to split among all entries that go the farthest (by round, must be perfect after first 2 rounds to qualify)
* Cost to enter is 0.0001 BTC for 1 billion entries (100,000 entries per satoshi). Paying 0.0001 BTC for 1 billion entries ensures random entries are economic losers.

What you win:
* Private key to 12yoo2eYjBLoqxqGw1BCM3BJ7uox4TT4hc. This private key will unlock all entry fees as well, as they are a "child" of this address.
* Furthest in tournament bonus.
* All media attention to being the first one to ever produce a perfect bracket!

How to enter:
* I can't host a website with 10+ billion entries
* Create a .txt file in very specific format with up to ~20 million entries on your own computer (file must be less than 250 MB compressed)
* Using EC math, prove this file exists by sending at least 1 satoshi per 100,000 entries to the public key of 12yoo2eYjBLoqxqGw1BCM3BJ7uox4TT4hc + sha256 checksum of file.
* I'll pay for the first few billion entries, just post checksum and how many entries are in it. Please no random files.
* post your checksums and transactions as well as how many entries

To claim a prize:
* entry filesize must be be less than 250MB (compressed). This is about 20,000,000 entries
* entries must be paid in full (100,000 entries for 1 satoshi)
* SHA256 of file must be sent to a specific address, and must have 1 confirm in the blockchain by tipoff on March 19th (approximately 11:00am ET)
* MUST POST any live entries 24 hours before the start of Sweet 16 games (March 26th). The whole point of this is the fun of hitting a perfect bracket in a pool for the first time.
* MUST MAKE AVAILABLE for public download your picks.txt file for verification of checksum 24 hours before tipoff on April 4th.
* May be asked to post bounty before I start downloading GBs of data.
* multiple winners will split the pot.
* no winners means it will roll over to 2016


The FORMAT of your .txt
* hex representation of the first 60 games (000000000000000 - FFFFFFFFFFFFFFF)
* Final 3 games are "E,W,S,M"
* Standard bracket (1v16, 8v9, 5v12, 4v13, 6v11, 3v14, 7v10, 2v15)
* Working down, assign '1' for top team victory, and '0' for bottom
* East round 1 (00-FF)
* West round 1 (00-FF)
* South round 1 (00-FF)
* MidWest round 1 (00-FF)
* East round 2 (0-F)
* West round 2 (0-F)
* South round 2 (0-F)
* MidWest round 2 (0-F)
* East round 3 and West round 3 (0-F)
* South round 3 and Midwest round 3 (0-F)
* East round 4, West round 4, South round 4, Midwest round 4 (true/false) (0-F)
* round 5 participant (E, W, S, M)
* round 5 participant (E, W, S, M)
* OVERALL WINNER (E, W, S, M)

Using 2014 as an example, the perfect bracket was:
DFDF95F39AB22E3EME (or DFDF95F39AB22E3MEE)

The 2013 tournament perfect bracket was:
9F89F6DF828C66FMSM (or 9F89F6DF828C66FSMM)
