One big lesson @AugurProject and @veil taught us is how difficult it is to write precise markets. Below is a list of all controversial, ambiguous, and misleading markets so far: 👇
1) Will the weather be good for the Bastille day military parade in Paris tomorrow.?
The market description never defined what "good weather" exactly meant and thus the market ended up resolving as invalid.

2) Which party will control the House after 2018 U.S. Midterm Election?
@realPoyoPoyo's intent was Republicans since they controlled the House when the market expired on Dec 10. Yet after 6 rounds and 1458 REP staked in disputes the market finally resolved Democrats.

3) Will Ethereum's Constantinople fork happen successfully by 2019-02-28T00:00:00Z?
When the market was created the fork was planned btw Jan 27-29. It ultimately happened just after the market expired at midnight, and those who didn't read the timezone carefully were mislead.

4) Will GRIN/USD be listed on CoinMarketCap by March 16, 2019?
GRIN/USD can mean either GRIN denominated in USD (Veil's intent) or the literal GRIN/USD trading pair. Veil actually halted trading on the market and later resolved it as YES. It is currently being disputed on Augur.

5) Will 2020 presidential candidate Andrew Yang have 250,000 or more Twitter followers on April 1, 2019?
He changed his Twitter handle from @andrewyangvfa to @AndrewYang. The resolution source is set to @andrewyangvfa and it never specified what happens when the handle changes.

What's the takeaway from all of this? Because markets are immutable once published on the chain, one needs to address all possible edge cases in the description. Right now the community is discussing drafting templates for common market topics that will help eliminate ambiguity.
This also shows that lawyers exist for a reason and what happens when you replace judges with a decentralized oracle system. 😂
