This billboard is Ethereum backed so you can own and control it, once you buy a billboard chunk to advertise your site, personal webpage or whatever you want to show on
it, you own that piece of the boards, that means that you can update it at any time or if want you can even sell it.
Think about it as a billboard in the internet where you can advertise your site , but at the same time you own part of it. So the billboard becomes a real estate market where you own fields or chunks in the billboard and you can build what you want there or sell them at any at the price you consider. All this behaviour is backed by a contract defined in the Ethereum blockchain.
The billboard is divided in chunks of 10 by 10 pixels i.e. 100 pixels, a chunk cost a symbolic 0.001 ETH i.e. a few cents.Once you buy the chunk you own it, so you can set the content and associated url and title that you want using the controls below. But as this is backed by the Ethereum network you own it so you can sell it at the price you choose and at any given time through the sell interface. If you are connected to the network through MetaMask you will also see the "live" update of the board.
The billboard will show your desired pixels, the title or description you choose and will lead to the webpage of your choice. But thanks to the Ethereum blockchain capabilities you can edit it at any, so if you change your logo
you can change it in the board too, also if you change your brand name or your webpage url
The billboard is backed in the blockchain and will remain there forever that means that you or anyone can retrieve it at any time.
Once you own a piece of the board it is up to you to set what's on it: the picture, to the title and the url. You can think of it as owning a terrain where you can build your house as you wish. Of course you are the owner so you can sell it at any moment and at any price you want. As in a real estate market you can buy chunks of the billboard , and sell them later at they price you choose. So for example you can buy a chunk at the initial price of 0.05 Ether and sell it later a 0.2 Ether, Once someone buy it, you just click the withdraw button and the money will be send to your account.
