Step 3


Build and run your application using smart contract templates and a simple, web-based user interface.

contract Users {
                        // Here we store the names. Make it public to
                        // automatically generate an accessor function named
                        // 'users' that takes a fixed-length string as an arg
                        mapping (bytes32 => address) public users;
                        // Register the provided name with the caller address.
                        // We don't want them to register "" as their name.
                        function register(bytes32 name) {
                        if(users[name] == 0 && name != ""){
                        users[name] = msg.sender;
                        // Unregister the name with the caller address.
                        function unregister(bytes32 name) {
                        if(users[name] != 0 && name != ""){
                        users[name] = 0x0;
