Rules:

The minimum puzzle reward must be 1mBTC (0.001 BTC).
The first part of your title must start with [Easy] [Medium] [Hard] [Expert] for difficulty levels, or [Meta] for general posts.
In the title, add the reward after the difficulty level.
If you are the OP and the puzzle is solved, flair your post with [SOLVED].
If the reward is not Bitcoin, you MUST put what it is in the title.
If you solve a puzzle, please describe what you did if the OP allows, and please post the result in a spoiler. If you don't put it in a spoiler you may be banned.
If you don't want to claim the reward but prove you have solved the puzzle, post in the thread with the first two and last two of the private key in this form: "I have solved the puzzle! Proof: AA...ZZ"

Title Example: "[Easy] [1mBTC] Find the address in this picture!"
