The discussion primarily revolves around a proposal put forth by Nandy.eth to extend support for v3 AAVE-ATOKEN (v3 aAAVE) on Aave's Snapshot governance across multiple blockchains, including Polygon, Avalanche, Optimism, and Arbitrium. The intention behind this proposal is to extend Snapshot voting rights, currently exclusive to v2 aAAVE holders, to v3 aAAVE holders. This move is expected to incentivize v2 aAAVE holders to migrate to Aave v3 and expand Aave governance to AAVE token holders on new blockchains where Aave was not previously present before the launch of Aave v3.

The proposal also presents market data, indicating the distribution of Aave tokens across different blockchains, excluding Ethereum. The data reveals that the majority of Aave tokens are held on the Ethereum blockchain, with smaller quantities on Polygon, Avalanche, Arbitrium, and Optimism.

However, the proposal does not shy away from highlighting potential risks. If approved, it would grant governance power to all v3 aAAVE token holders and expose Aave governance to other blockchains such as Arbitrium and Optimism. It's important to note that Aave tokens can be bridged between blockchains¹. The discussion thus presents a balanced view of the potential benefits and risks associated with the proposal, providing a comprehensive understanding of the topic.
