Hey bro,

You wrote excellently friend I love how you carefully explained proof of participation in a simpler and better term.

Steem power is a token influence used on the platform, it is used for upvoting and rewarding users who participate in contributing to the development of the platform

Steempower is very important in the Steem ecosystem, as you said it's used to efficieny upvote and downvotes Post on steemit. The steempower also rate your influence and commitment in the Blockchain world and just like other Blockchain the more users hold steem (which is steem Power) the higher the price would go in the Crypto market so therefore this is to say the growth of Steem blockchain depends on it's stalk-holers.

Thank you very much for sharing, please you can check my own entry here
