52 Week Photography Challange 2018

This year again photographer Dale Foshe has put up 52 week photography chanllange here.

Following, I just list them again for my ease of use. 😆

• Week 1 Vision: Look Ahead New year. New beginnings. New you. Look ahead. Interpret as you wish.
• Week 2 Composition: Color Harmony Get out your color wheel. Do opposites attract? Can there be harmony with opposite colors? Does the Hulk wear purple pants? Mix warm and cool colors.
• Week 3 Technical: Full Manual While the camera often determines shutter speed and aperture for the photographer, it doesn't know your creative intent. This week, challenge your self to assume creative control over the camera by using full manual mode. Select a subject where varying the aperture and / or shutter speed helps enhance the composition and visual qualities of the image.
• Week 4 Creative: Quiet Moment Peace

plasma in-flight exit approach
-  on mainchain user starts exit with tx-data(user signed and submited) and exits with last amount(in erc20) 
-  user also plases a bond amount 
-  there is fraud-prrof if user tries to exit with fraudulent tx then operator can submit in-flight tx with same nonce
-  this prevents fraud from operator side 
-  obviusly user won't exit with fake tx(where he is sending amount to someone) with less amount then his last accepted tx amount
-  if user tries to exit with any previous tx then in-flight tx then operator or anyone with greater nonce tx can strat challenge 
    and get bond amount and cancels exit
-  what happens when user and operator colludes ?
