I made 100 Tricky Stick puzzles for the Ethereum Devcon2 conference in Shanghai.
The first indication of disruption was raised by @tayvano of the MyEtherWallet.com team:
Apparently there was some talk of this puzzle on WeChat, but I avoid installing apps with mandatory backdoors and/or suck contact information.

Here’s the MyEtherWallet.com team – @tayvano, Kevin and @kvhnuke:
The Lefteris Karapetsas:
I attached one of these puzzles on Vitalik’s bag when I met him last year at the Sydney Blockchain Workshop, so he threw his bag away. So I went up the chain and gave the puzzle to one of the people who made the Vitalik, his waay-too-young-looking dad Dmitry:
This puzzle is a non-transferable physical token that becomes transferable after you have solved it. Sort of like The DAO‘s
transferFrom(...) functions. Your IQ also goes up 10%:
IQ(you) *= 110%.
And from David Burela’s WordPress post DEVCON2 report: Day 3 – Final day:
Few people cheated, but we won’t mention any names – @ledgerwatch aka Alexey and Dr. Christian Reitwiessner. Remember not to cheat as you will deprived yourself from solving one of the simplest puzzles ever!
About 5% of people I give these to solve the puzzle within 5 minutes. By dinner on the last night, many Ethereans had solved this puzzle. Well done!
Remember to play games with your colleagues so you know how they react in stressful situations. And this puzzle can be stressful when you are under pressure.
