Smart Contract Platform On Top of Bitcoin
RSK is an open source platform for Ethereum compatible smart contracts based on the Bitcoin network.
Truffle is a popular development framework with a mission to make smart contract development easier for developers. Amongst its features includes: a smart contract lifecycle management, a scriptable deployment & migrations, and automated contract testing and simple network management.
It also makes developing on RSK easier, with the ability to configure custom networks for RSK.
Truffle Boxes are sample applications in the form of project templates. Every Truffle box comes with libraries and tools already preinstalled, code that uses those libraries and tools, external scripts (if necessary), as well as helpful README's and documentation. Also some of them have front-end views, all the way up to complete example dapps. The Truffle boxes are in a single and easily-downloadable package and directly integrated into the Truffle command line.
You can create an empty project template, but for those just getting started, you need only type truffle unbox <box name> to download and prepare your box of choice.
RSK has its own specialized Truffle Boxes:
They come with everything you need to start using smart contracts on the RSK Network.
It includes network configs for:
Also Truffle has a Solidity smart contract as an example for deployment.
I will introduce each one of them.
The rsk-starter-box is a basic RSK box. The focus here is to show the network configurations for a local node (it is called regtest in RSK), Testnet and Mainnet.
It also includes a smart contract to store and retrieve a number, the name for the smart contract is called SimpleStorage and it is an example for deployment.
You will know the Truffle development console and how to interact with a smart contract using Truffle.
Compile, Deploy and Tests are included too.
It includes network configurations for Mainnet, Testnet and for a local node (it is called regtest in RSK). Deploy instructions and tests are included too.
It also has an user interface to interact with the smart contract using the library web3, it is a real dApp!
OpenZeppelin Contracts helps you minimize risk by using battle-tested libraries of smart contracts for Ethereum and other blockchains. It includes the most used implementations of the ERC standard.
The smart contract is a mintable ERC20 token. This means that, in addition to the standard ERC20 specification, it has a function for issuing new tokens.
The token smart contract will have only 7 code lines!
We are importing the ERC20Mintable from Open Zeppelin. This library itself imports several other libraries such as SafeMath.sol, the standards for this kind of token, and the capability to mint tokens.
rsk-react-box is a box that pairs RSK and Truffle with React in an easy to understand structure, meant for a web-based Blockchain application.
It uses the create-react-app template, which is a good environment for learning React, and is the best way to start building a new single-page application in React.
Create React App doesn’t handle backend logic or databases; it just creates a frontend build pipeline, so you can use it with any backend you want. Under the hood, it uses Babel and webpack, but you don’t need to know anything about them. (source: create-a-new-react-app)
A Create-React-Next-App is generated in the app directory.
Next.js is a lightweight framework for static and server‑rendered applications built with React. It includes out of the box styling and routing solutions, and assumes that you’re using Node.js as the server environment. To learn more check it out the create a next.js app in it’s official site.
Express JS is a minimalist web framework for Node.js.This box has a client-server application in the app directory.
In this article you were introduced to RSK Truffle Boxes, which comes with everything you need to start using Truffle on RSK networks.
So, have you chosen an RSK Truffle Box yet?
In the next tutorials you will learn step-by-step how to use some of these RSK Truffle boxes.
