Blockchain technology has every potential to bring more trust, efficiency, and transparency to day-to-day transactions. As a result, industry leaders are planning budgets for it and making pilot projects for their organizations. CBCA helps uninitiated blockchain leaders by discussing the steps and challenges of implementing blockchain technology within an organization.

Blockchain initiatives across industries are growing faster these days, and how to implement blockchain  is a part of a company’s transformational journey.


84 percent of executives use blockchain in their operations at least to a certain extent. However, implementing blockchain poses its own challenges. It is highly recommended to implement in phases considering the present situation and future plans of the organization. Let’s see how.

Steps involved in Blockchain Implementation

The steps involved are:


1. Identify the use case

The first step is to identify, clarify, and organize your needs. Understand the exact problems you want to solve and confirm whether implementing blockchain solutions will help to solve them. It is recommended to start with a pilot project, analyze the results, and then implement them on a larger scale.

PwC recommends these key questions that companies should consider before blockchain implementing technology.

  • How does blockchain disrupt the business?
  • Is the purpose of the business application understood?
  • Is the technology resilient, scalable, and secure?
  • What are the impacts of blockchain technology on the market?
  • How does blockchain reduce cost or improve customer service?
  • How should blockchain be governed and administered?
  • Are we considering a 3-5-year plan for blockchain?

PwC studies further caution that putting the effort now and applying them in the next IT budget cycles will avoid “regret spend” later on.

2. Create a proof of concept

Once you identify the use case, it is essential to create a valid Proof of Concept (PoC). PoC is nothing but a strategic procedure to evaluate how blockchain would be feasible for the business. Understanding the planning phase and evaluating steps direct you to create your Proof of Concept. Here are the steps to create a proof of concept.

  • Develop a set of guidelines
    to explain the business project
  • Create a prototype
    to involve design, code, sketches
  • Test the prototype
    to understand the business happenings
  • Analyze the MVP
    to incorporate the top features

3. Choose the blockchain platform

Some of the popular blockchain platforms include:

  • Ethereum: determines the potential growth rate of the business
  • Quorum: eliminates the data tampering in business transactions
  • Hyperledger Fabric: creates private blockchain applications for businesses
  • Stellar: develops applications for companies and organizations
  • Corda: make direct transactions through smart contracts with full security
  • Open chain: maximizes each aspect of business’s human resource management
  • Multichain: optimizes human resource work at the professional level

When choosing a blockchain platform ascertain whether the technical team is organized and they have an open-source station. The platform should suit your budget too. The transition from a successful proof of concept to full-scale implementation is challenging for both governments and enterprises. Therefore, it is necessary to consider these factors:

  • Gaining a general level of understanding of the technology by business leaders
  • Creating a strategy and vision for blockchain technology usage
  • Engaging with regulators to establish clarity and stability as well

This assurance will help to realize the tangible benefits as promised.

4. Choose the right consensus protocol

In a distributed network, consensus protocol alone can create an indisputable system of agreement between the devices. Take a look at the wide variety of consensus protocols available.

  • Proof of Work
    Counters cyber-attacks such as DDoS and validate transactions to produce new blocks
  • Proof of Stake
    The developer is selected for the subsequent block by combinations of random qualifications such as age, wealth, and performance.
  • Delegated Proof of Stake
    Ensures transaction approvals as a fixed set of miners are involved in the activities
  • Byzantine Fault Tolerance (BFT)
    Achieve consensus by depending on the same value even when the network components are unresponsive.
  • Proof of Weight
    Achieve agreement by depending on the weight of the cryptocurrency the miners have.

5. Build an ecosystem

Blockchain technology is at its best when stakeholders take part. However, to create a new industry ecosystem, a community within an organization is the need. Because they can understand the technology’s potential and improve standards and rules.

PwC reports that the stakeholders decide the rules, ensure the costs and benefits, use the right control framework, affirm governance mechanism, audit and validate the blockchain functionalities. Here are the steps to build an ecosystem.

  • Start with smaller ecosystems
    Build a blockchain with a few stakeholders who can expand it later on
  • Find a community
    Broaden your network through blockchain consortia and explore more industry applications
  • Conduct a competitive analysis
    Analyze competitors or new entrants and look for partnership potential
  • Standardize data with a robust governance
    Develop standard naming conventions and system-wide data models

6. Determine rules of engagement and navigate uncertainty

The new blockchain ecosystem should solve the organization’s issue and comply with the processes. privacy implications, compliance, and cybersecurity issues must be addressed. Or else, the ground processes might be forced to get redesigned. PwC suggests that businesses must comply with emerging blockchain policies and best practices while monitoring evolution in regulations. Here are the key plans.

  • Confront risks
    Involve cybersecurity, compliance, and legal team to blockchain development team while building a framework.
  • Consider privacy implications
    Invest in data and its processes. Data immutability is an important feature of blockchain and it should fit into privacy strategies like GDPR.
  • Use current regulations
    Stay agile. Current regulations are applied in different ways. So, stay agile to adapt and remain compliant.
  • Monitor evolving regulation:
    The laws pertaining to data usage and protection keep changing and depend on blockchain operations. So, involve regulators.

Challenges faced while implementing blockchain

You may face the following challenges while implementing blockchain and establishing the system for the long run.

1. Difficult user interfaceAll of the clients you handle may not be good at using technology. If your system is simple, you can attract maximum customers.

2. Scarcity of skilled blockchain developersThe blockchain industry experiences a low supply of skilled blockchain developers. Smaller businesses may have to offer competitive incentives to attract and retain blockchain experts.

3. Varying blockchain regulationThe regulations keep changing and are updated often. The challenge is how one should consider and incorporate the regulation effect in their organization activities.

4. Scalability issuesThe scalability issue is still there, though there are several approaches suggested in the literature to improve scalability. Blockchain bridge forms a link for interaction and communication between blockchain systems and might overcome scalability issues.

5. Security issuesThe 51 percent attack theory has made blockchain vulnerable to several threats from hackers. It is the most disturbing issue every organization faces to date.

6. SpeedTransaction processing speed (TPS) is again one of the major bottlenecks that hamper mass commercial adoption of blockchain.
