The discussion primarily revolved around the proposal of initiating liquidity mining for various pairs. Ghosts_in_the_code made a significant contribution by suggesting the start of liquidity mining for the AAVE/ETH pair on a zkrollup like Loopring. This proposition was seen as a potential solution to reduce gas fees, a common concern among users.

In addition to this, Ghosts_in_the_code also proposed the initiation of liquidity mining for pairs such as aUSDC/USDC, aETH/ETH, and similar pairs. This innovative idea was seen as a way to allow users to swap into Aave assets without the burden of gas fees.

In conclusion, the discussion was centered around the exploration of methods to reduce gas fees and improve the efficiency of swapping into Aave assets. The suggestions put forth by Ghosts_in_the_code were seen as potential solutions to these issues, indicating a positive direction for future developments.
