The two highlighted a September 2020 audit report in which the U.S. Treasury Department's Inspector General for Taxation pointed out that the IRS could not identify taxpayers who supported cryptocurrencies due to lack of reporting.

16. Uniswap Labs launches a new indicator FLAIR to measure the competitiveness of LPs in AMM pools
According to the official blog, Uniswap Labs announced the launch of a new indicator FLAIR (Fee Liquidity Adjusted Instantaneous Return) to measure the competitiveness of LPs in AMM pools, which is designed to measure any number of LP positions over any period of time, including a single point in time. FLAIR can be used to attribute historical performance, backtest LP strategies, or optimize new liquidity deployment. Uniswap Labs said that LVR (Loss Versus Rebalancing) is a commonly used indicator for evaluating LP order flow, focusing mainly on information imbalances between LPs and traders. However, such indicators cannot explain the competition between LPs in the same pool; FLAIR is a new indicator that complements LVR to measure the competitiveness of LPs and capture the dynamic behavior of LPs in the pool. FLAIR reflects reasonable LP economic intentions, that is, LPs increase competition within the pool by allocating funds to pools with higher returns, rebalancing liquidity within the range, and deploying liquidity during high-fee periods.
