Snapshot allows for off-chain vote signaling. It is 100% gasless. Anyone can participate by creating proposals and voting for them. You are able to select start and stop times, as well as a block height which will be used to gather on-chain data for the front end (eg how much MKR you held at a given block). I thought this could be helpful in giving some weight to forum polling and maybe replace on-chain polling, if the stars align . High gas fees have been a deterrent for our current polling system, and it would allow for more MKR insight in our casual forum polls.
I’ve been chatting with Fabien in their discord, and invited him to help answer any questions we may have.
