Custom Blockchain vs. Public Blockchains: Choosing the Right Path for Your Business

By Udit Agarwal


In blockchain technology, businesses are faced with the crucial decision of whether to opt for a custom blockchain solution tailored to their specific needs or to leverage existing public blockchains. Each approach has advantages and considerations, making it imperative for businesses to carefully weigh their options before proceeding. Let’s explore the key factors to consider when choosing between a custom and public blockchain for your business.

Custom Blockchain Solutions:

Custom blockchain solutions offer businesses the flexibility to design and implement a blockchain network that caters precisely to their requirements. By building a custom blockchain, companies can address specific use cases, incorporate proprietary features, and fully control the network’s governance and operation. This level of customization can be particularly advantageous for enterprises operating in highly regulated industries or those with unique business processes that require tailored solutions.


  • It is tailored to specific business needs and use cases.
  • Greater control over network governance and operation.
  • Ability to incorporate proprietary features and enhancements.
  • Enhanced security and privacy measures tailored to business requirements.
  • Potential for improved scalability and performance through optimization.


  • Higher upfront development costs and resource requirements.
  • Longer development and deployment timelines compared to leveraging existing solutions.
  • Maintenance and support overhead for ongoing network management.
  • Limited network effects and interoperability compared to public blockchains.
  • Potential challenges in achieving consensus and network security without an established ecosystem.

Public Blockchains:

Public blockchains, such as Bitcoin and Ethereum, offer businesses the benefits of a decentralized, transparent, and globally accessible infrastructure without the need to build and maintain a custom blockchain from scratch. By leveraging existing public blockchains, businesses can tap into established ecosystems, benefit from network effects, and access a wide range of tools, protocols, and development resources. This approach is well-suited for businesses seeking interoperability, standardization, and compatibility with existing blockchain networks.

Custom Blockchain


  • It has established ecosystems with broad developer support and tooling.
  • Interoperability and compatibility with existing blockchain networks and protocols.
  • Access to global user bases and network effects.
  • Lower upfront development costs and faster time-to-market compared to custom solutions.
  • Built-in security features and robust consensus mechanisms.


  • Limited customization and flexibility compared to custom blockchain solutions.
  • Lack of control over network governance and operation.
  • Potential scalability and performance limitations due to network congestion and transaction fees.
  • Privacy concerns associated with public and transparent transaction data.
  • Regulatory and compliance challenges, particularly in highly regulated industries.

In conclusion, choosing between a custom blockchain solution and public blockchains depends on various factors, including your business’s specific requirements, use cases, budget constraints, and regulatory considerations. While custom blockchain solutions offer unparalleled customization and control, they require substantial investment and resources. On the other hand, public blockchains provide accessibility, interoperability, and network effects but may lack the customization and control of custom solutions. Ultimately, businesses must carefully evaluate their options and choose the path that best aligns with their strategic objectives and long-term vision for blockchain adoption.
