Are you trying to find out how to create a labor exchange agency using blockchain?

This is a market segment that still has lots of room for growth.

Blockchain: What it is, and how it can help with Labor Exchange Agency

Blockchain is a technology with huge potential to transform many aspects of society and business, and it can transform labor exchanges as well. However, let’s understand the characteristics of blockchain first, which are as follows:

  • It’s a “peer-to-peer” (P2P) network, and public blockchains networks allow anyone to join. Private blockchain networks allow only trusted parties to join, though.
  • Each computer on a blockchain network is called a “node”. Nodes maintain a shared ledger containing all transactions, therefore, blockchain is also called “Distributed Ledger Technology” (DLT).
  • Blockchain uses advanced security features like digital signatures, data encryption, cryptographic hash functions, and consensus algorithms to protect data against tampering.
  • Its decentralization, distributed ledger, and security features offer transparency, audit trail, and efficiency.
  • Blockchain platforms like Ethereum, NEO, and EOS offer smart contracts, which are immutable pieces of code that transfer cryptographic assets when predefined conditions are met. These are transparent, moreover, their execution is autonomous and irreversible. They have the potential to improve contract administration.

Read more about blockchain in “How to build your own blockchain using Node.js”. With its immutability and distributed ledger, blockchain can significantly improve how labor exchanges function.

Creating a labor exchange using blockchain

You need to take the following steps to create a labor exchange using blockchain:

1. Agree on the project scope

Hire a project manager (PM), an IT architect, and a team of business analysts first. You need to hire people with sufficient experience in blockchain development projects.

This team needs to discuss with the business stakeholders and gather the business requirements. Define the project scope based on this, which should include offering a web app.

2. Prepare a comprehensive project plan

Blockchain development projects tend to be complex, therefore, you need a comprehensive project plan. You need to consider several questions, e.g.:

  • Do you need a cryptographic token?
  • Should you use a public or private blockchain?
  • How to find the right blockchain network hosting provider?

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

3. Opt for a private blockchain since you will deal with sensitive data

A labor exchange needs to comply with stringent labor laws, moreover, it must comply with privacy regulations. Labor exchanges deal with sensitive data such as identity, and you need to protect them adequately.

A labor exchange will likely help millions of job-seekers through re-employment services, moreover, it might serve thousands of businesses including, public employment offices, federal agencies, and national associations linked with job search assistance. Therefore, It needs scalability and high transaction throughput.

Given these, I recommend that you use a private blockchain. They offer the following advantages:

  • You can let only trusted parties join, therefore, sensitive information isn’t out in the open.
  • You can choose consensus algorithms that enable scalability and high performance.

Read our guide “Public vs private (permissioned) blockchain comparison” for more information.

4. Select an appropriate enterprise blockchain framework

Building an enterprise blockchain can be complex, however, using an enterprise blockchain framework makes it easier. I recommend that you use Hyperledger Fabric, which has the following advantages:

  • Fabric, as it’s commonly called, is an open-source framework for creating enterprise blockchain networks.
  • This framework is part of the Hyperledger Consortium, which is an industry group, and technology giants such as IBM, Cisco, etc. contribute to it. As a result, there is a continuous effort to improve the framework.
  • Fabric is scalable and performant, moreover, you can build a permissioned network using it.
  • You can take advantage of its modular architecture and pluggable components like consensus algorithms.
  • Fabric makes it easy to protect sensitive data with its “Channel” technology.
  • You can code “chaincodes”, i.e., smart contracts in Fabric parlance in Java, Golang, and Node.js.
  • It also offers a “Hardware Security Model” (HSM) to ensure additional security to digital keys.

Our guide “Pros and cons of Hyperledger Fabric for blockchain networks” explains its advantages in detail.

5. Find the right blockchain network hosting provider

You need to find an appropriate blockchain network hosting provider so that you don’t need to manage IT infrastructure while building your blockchain network. I recommend “Blockchain on AWS” since it offers the following benefits:

  • It supports Fabric, moreover, it uses the excellent cloud capabilities of AWS.
  • AWS supports both decentralized and centralized ledgers. Members own peer nodes in the case of a decentralized ledger, whereas a trusted authority manages a centralized ledger and shares it with others. You get the key advantages of blockchain in both cases.
  • You can use the Amazon “Quantum Ledger Database” (QLDB) for this project, which is a fully managed ledger database.
  • AWS offers its fully managed “Amazon Blockchain Service”, and you can use it along with the “AWS Blockchain Templates” to build a blockchain network quickly.

I have explained “Blockchain on AWS” in “Best blockchain network hosts”.

6. Select the right Platform-as-a-Service (PaaS) platform for the web app

You also need a “Platform-as-a-Service” (PaaS) to deploy the web app, and AWS Elastic Beanstalk is the right choice for this. It manages the cloud infrastructure, networking, operating system, middleware, and runtime environment, therefore, you can focus on developing the web app.

You can easily integrate 3rd party APIs, moreover, you can use the AWS DevOps services on Elastic Beanstalk. Read more about it in “10 top PaaS providers”.

7. Prepare a cost estimate for the project

You need to prepare a cost estimate for this project to get the necessary budgetary approvals to proceed. This involves estimating the development manpower, moreover, you need to estimate the cost of hosting Fabric on AWS. Our guide “How much blockchain cost for software development?” can help you to prepare this estimate.

8. Form the complete project team

You need to form the complete project team now, and hiring competent blockchain and web developers have importance here. Our guide “How to find a good software developer” can help you.

You need the following roles in the team:

  • UI designers;
  • Web developers with Node.js skills;
  • Blockchain developers with experience in developing apps on Hyperledger Fabric;
  • Testers;
  • DevOps engineers.

9. Design the user interface of the web app

You need a user-friendly user interface (UI), therefore, you should follow appropriate guidelines. I recommend that you read “User interface design guidelines: 10 rules of thumb” for guidance.

10. Create the blockchain network and develop chaincodes

It’s time to create the blockchain network on AWS, therefore, I recommend that you take the following steps:

  • Create a Hyperledger Fabric blockchain network including the first member.
  • The next step is to create an endpoint.
  • Set up a client to communicate with the network.
  • This is a permissioned network, so you need a member admin for this system. You now need to set up such an admin.
  • Users for this system will need to execute transactions, therefore, the system needs peer nodes. Start with creating one peer node, subsequently, you need to add more.
  • You now need to code “chaincodes”, therefore, I recommend that you read “Chaincode tutorials”.
  • You need to create a channel to process sensitive data.
  • A labor exchange using blockchain will involve sending sensitive labor market data from one user to another, therefore, you need to create a joint channel. You also need to invite the relevant members.

You can read “Get started creating a Hyperledger Fabric blockchain network using Amazon Managed Blockchain” for guidance.

11. Develop the planned web app

I recommend that you use Node.js for developing the planned web app. Node.js is a popular open-source runtime environment based on JavaScript, and many developers know it. It offers more advantages, e.g.:

  • js is suitable for creating scalable and performant web apps.
  • There is a large developer community that supports it, and this community has developed many open-source tools and frameworks.

I have explained the benefits of using Node.js in “10 great tools for Node.Js software development”.

Developing this web app involves the following:
