Here is a contract that can assert that it is art.
init:
contract.storage[1000] = "may be"
code:
if msg.data[0] == "toggle":
if contract.storage[1000] == "is":
contract.storage[1000] = "is not"
else:
contract.storage[1000] = "is"
It toggles its status as art when sent a message instructing it to do so.
Here’s what the UI for the contract looks like:
Here it is while the artistic state of the contract is being toggled:
And here it is after being toggled: Anyone can change the contract from not being art to being art (and vice versa). We’ll look at a more advanced contract that uses behavioural economics to address this next.
