Wondering how to create a blockchain smart contract for your enterprise product?

You’ve come to the right place.

How to create a blockchain smart contract for your enterprise

I will now explain the steps to implement blockchain-based smart contracts in your enterprise, which are as follows:

1. Project planning

Onboard a project manager, an IT architect, and a team of business analysts, and look for their experience in blockchain implementation. Your planning process will cover the following:

  • Defining the requirements and business logic for your project;
  • Determining the type of blockchain to use;
  • Planning for hosting the blockchain network;
  • Identifying the technology stack;
  • Budgeting the project;
  • Onboarding a development team;
  • Developing the blockchain network and smart contracts;
  • Reviewing the code;
  • Deploying smart contracts and your blockchain application.

Read our guide “What to plan for when undertaking blockchain software development?” for more insights.

2. Choose the right kind of blockchain

You will likely not develop a cryptocurrency as part of your project, therefore, you need to choose the right kind of blockchain. Cryptocurrencies like Bitcoin and Ether use public blockchain networks.

You can’t use such a network due to the following reasons:

  • They are open to all, whereas, you can only allow trusted participants to join your enterprise blockchain network.
  • Public blockchain networks don’t allow data privacy, whereas, you will likely have sensitive data in your enterprise. You will need to implement access control.
  • A public blockchain network like Bitcoin isn’t performant and scalable enough, whereas, you need high transaction throughput and scalability in your enterprise.

You will need to use enterprise blockchain. It allows the setting up of permissioned networks and access control, moreover, it’s scalable and performant.

3. Find a hosting provider for your blockchain network

Since enterprise blockchain networks aren’t already existing public blockchain networks, you will need to build a network. You need a hosting arrangement for this.

Well-known cloud computing service providers offer hosting arrangements for enterprise blockchains. You can choose one of the following providers:

  • “Blockchain on AWS”: This is the AWS blockchain platform, and it leverages the impressive cloud capabilities of AWS.
  • SAP Cloud Platform “Blockchain as a Service” (BaaS) is a comprehensive platform.
  • “Microsoft Blockchain on Azure” is the BaaS offering from Microsoft.
  • “IBM Blockchain Platform” utilizes the cloud capabilities of IBM.

All of these BaaS platforms enable you to use reputed enterprise blockchain frameworks like Hyperledger Fabric, R3 Corda, etc.

Read more about these BaaS platforms in “What are the Best Blockchain Network Hosts in 2023?“.

4. Choose an appropriate technology stack

Find the enterprise blockchain framework that suits your requirements. You can choose from Hyperledger Fabric, R3 Corda, etc. I recommend Hyperledger Fabric. It has many advantages, e.g.:

  • It’s an industry-agnostic enterprise blockchain framework.
  • Fabric enables you to set up a permissioned blockchain network, which is important in the enterprise context.
  • Hyperledger Fabric has a modular architecture, and developers can easily create pluggable components like custom identity management, etc.
  • Fabric offers performance and scalability, which are important in the enterprise context.
  • You might need a process for sensitive data management. That’s easy with Fabric, thanks to its “Channel” technology for partitioning digital assets.
  • Fabric offers rich querying capabilities.
  • You can use the “Hardware Security Model” (HSM) of Fabric, which helps to secure digital keys.

Read “Pros and cons of Hyperledger Fabric for blockchain networks” to learn more about Fabric.

You can code smart contracts in Fabric, and these are called “chaincodes”.

5. Budgeting for your project

You will need to estimate the cost of your project, which involves the following cost elements:

  • Blockchain infrastructure costs;
  • The cost of frameworks and tools as applicable;
  • Development manpower costs;
  • Other administrative costs.

You can follow our guide “How much does it cost to build a blockchain project?” to estimate this project.

6. Onboard your complete development team

You will need to form the complete development team, therefore, focus on onboarding the following roles:

  • UI designers who are experts in designing interactive user interfaces and user-friendly app experiences. Designers should have basic design skills in wireframing and prototyping. These are essential to test-design multiple app-building approaches.
  • UI designers should be able to design mobile app interfaces according to the app store guidelines. For example, Android developers should be familiar with Material Design Guidelines, and iOS developers should design iOS apps according to Human Interface Guidelines;
  • Web developers with JavaScript, especially Node.js, skills, if you are building a web app. They should be skilled in using web development frameworks like Angular, Ruby on Rails, Vue.js, etc. to build optimized and secure web apps efficiently;
  • Native Android developers with proficiency in Java and Kotlin programming language, if you are building an Android app;
  • Android developers should also be experts in using Android development tools like Android Studio IDE and Android Jetpack libraries for writing high-quality code efficiently;
  • Native iOS developers with Swift skills, if you are developing an iOS app;
  • iOS developers should be familiar with Apple tools and platforms like XCode IDE for building optimized apps for the Apple store swiftly;
  • Hybrid app developers to build apps for multiple mobile operating systems. Hybrid app developers should be skilled in web technologies like JavaScript, Html, etc.;
  • Developers should also be familiar with cross-platform app development frameworks. Frameworks like Xamarin, Ionic, Flutter, etc. provide developers with extensive library components. They assist app developers in deploying mobile apps on multiple mobile devices using a single code-base;
  • Hyperledger Fabric developers with experience in smart contract development;
  • Testers with experience in using automated testing tools like Selenium for testing web applications, Espresso for Android apps, and XCTest for iOS app;
  • DevOps engineers, able to work with continuous server integrations, configuration management, dependency monitoring, and cloud systems analytics. They should be able to automate app deployment and work with containers;
  • Cloud Computing engineers who are familiar with different cloud services like software as a service, platform as a service, and Infrastructure as a service provided by companies like Microsoft, IBM, and Amazon;
  • Your cloud computing professionals should be experts in choosing the appropriate cloud service model for your application.

You could find it hard to onboard competent developers, however, our guide “How to find a good software developer” can help.

7. How smart contracts Work? Study similar projects

Smart contracts are often open-source, therefore, many organizations let other developers view their smart contracts. Based on your own smart contract use case, you might want to study existing smart contracts that are similar.

You can get key ideas by studying other smart contracts. Organizations that allow others to view their smart contracts typically store them on repositories like GitHub.

E.g., Microsoft Azure lets you see many of their smart contracts on the GitHub repository named “Applications and smart contract samples”.

8. Build your blockchain network

In this guide, I assume that you will use the IBM Blockchain Platform and Node.js to build your blockchain network using Fabric.

Fabric offers a Node.js SDK, and you can read about it in “Hyperledger Fabric Client (HFC) SDK for Node.js”.

The following points about this SDK are noteworthy:

  • It offers robust APIs to communicate with the Fabric blockchain network.
  • You can configure your network by following the instructions in the GitHub repository of the Fabric Node.js SDK.
  • Your development team can use this SDK to submit transactions to Fabric chaincodes, moreover, the SDK offers querying capabilities.
  • You can create channels for confidential transactions using this SDK.
  • This SDK helps you to create different types of nodes on the network, furthermore, it enables you to register new users and revoke existing users.
  • You can use this SDK for chaincode deployment and monitoring events at block and transaction levels.

Use this SDK on the IBM Blockchain Platform, which involves the following:

9. Code chaincodes

Now that you have built your blockchain network, you can code chaincodes. Read “Writing smart contracts” to learn how to write chaincodes on the IBM Blockchain Platform, and code them using Node.js.

 10. Review chaincodes

You ought to test chaincodes, i.e., smart contract code in the Fabric parlance. However, that’s not enough since smart contracts are tamper-proof once you deploy them. You also need to review them thoroughly.

Do the following to review your chaincodes:

  • Lock down the source code and conduct a preliminary code review.
  • Conduct a static code analysis followed by a code quality analysis.
  • Analyze the presence of known vulnerabilities like reentrancy, shadowing of variables, overflows, incorrect cryptographic signature validation, etc.
  • Analyze whether the chaincodes meet their functional requirements.
  • Report all observations and bugs and track their closure.

Our guide “Undertaking a blockchain code audit and its importance” can help you.

11. Test and deploy your chaincodes and app

It’s now time to test and deploy your chaincodes and app, therefore, follow the instructions in “Getting to know the Hyperledger Fabric continuous integration (CI) process”. This guide covers the following:

  • Use Docker containers for your deployment;
  • The “Build” process;
  • Use Jenkins for CI (continuous integration);
  • Test smart contracts;
  • The “Release” process.

Do the following:

  • Deploy smart contracts (your chaincodes).
  • Add network API endpoints to your app.
  • Enroll an app to prove its authenticity. Register the app using the client-side certificates that you generated while enrolling it.
