Billboard: Officially launched on BOT Chain Mainnet

Billboard is officially launched on BOT Chain Mainnet. There is one board, and anyone can put their words on it. To take it, you pay at least 10% more than the ad you cover, and your whole payment goes to the wallet you replaced.

So when someone covers your ad, you collect what they paid. Every ad that ever went up stays on record on BOT Chain, and there are no admin keys.
