Smart contract messages

To communicate with Smart contracts. We use "messages".

It's possible to pass two kinds of messages:

• messages that change a smart contract's state should be sent as transactions;

• messages that don't change a state could be called by using RPC calls.

Let's try to read our smart contract value by get() message call.

Second, let's change a smart contract state by sending a "message", send flip() message that flips smart contract boolean flag.

Using these two kinds of messages, your DApp can easily write and read the smart contract data. Have fun!
