Lighter announced the launch of its token LIT today and completed its airdrop. Based on Eastern Time, the probability of a "Lighter airdrop on December 30th" on Polymarket is as high as 95%. However, the exact airdrop date is still within Polymarket's UMA (Unified Oracle) dispute resolution period. A user submitted a dispute to the UMA oracle, arguing that the "Lighter airdrop on December 29th" result should be "yes." Based on Eastern Time, the Lighter airdrop occurred within an hour of December 29th and December 30th, which may have caused the dispute. Odaily Note: Polymarket relies on the UMA oracle to determine the outcome of events. After an event occurs, anyone can report the result to UMA. There is a dispute period after the report is submitted, during which anyone who believes the report is incorrect can raise a dispute. If there is no dispute, the report results will be accepted; if there is a dispute, UMA's dispute resolution mechanism will determine the final result. The dispute resolution method involves UMA token holders voting to determine the correct result. UMA will incentivize honest behavior and punish malicious behavior.
