the way this was done at odysee called boosting and anyone could stake coins without leaving their wallets to any other post/user and that ranks up the score, not sure if a mechanism like this is doable with LN/zaps so you don't need to send coins but can keep boosting different npubs or withdraw and spend the coins when not needed anymore 

 Interesting. Almost like a publicly verified identity based on value or contribution to the social network?
