Using SIMBA Chain

Here is a playlist on the SIMBA Chain Youtube channel to get you up to speed on using the dashboard.

Smart Contract¶

pragma solidity ^0.4.24;

contract Application {

function Application() public {} enum Assets {

chatRoom, message

} Assets _message = Assets.chatRoom; Assets _createRoom = Assets.chatRoom; Assets _sendMessage = Assets.message;

function message (: string assetId) /* parameter needed for linking assets and transactions */

public {}

function createRoom (: string assetId, /* parameter needed for linking assets and transactions / string name, / optional parameter / string createdBy) / optional parameter */

public {}

function sendMessage (: string assetId, /* parameter needed for linking assets and transactions / string message, / optional parameter / string sentBy, / optional parameter / string chatRoom, / optional parameter / string _bundleHash) / optional parameter */

public {}

}
