Choosing the Right Blockchain
Understand the key differences to determine which blockchain architecture best fits your business needs.
| Feature | Private Blockchain | Public Blockchain | Consortium Blockchain |
|---|---|---|---|
| Participants | Single organization controls the network. | Open to anyone to join and participate. | Controlled by a pre-selected group of organizations. |
| Permissions | Permissioned (Invitation-only). | Permissionless (Anyone can join). | Permissioned (Vetted members). |
| Consensus | Controlled by the owner (e.g., Raft, IBFT). | Decentralized (e.g., Proof of Work, Proof of Stake). | Controlled by member nodes (e.g., Raft, IBFT). |
| Speed | High (Fewer nodes to validate). | Low (Many nodes, complex algorithms). | High (Fewer nodes). |
| Data Privacy | High (Data is not public). | Low (All transactions are public). | High (Data can be private to participants). |
| Best For | Internal enterprise processes, data control. | Cryptocurrencies, public records, censorship-resistance. | B2B collaboration, industry-wide platforms. |

Frequently Asked Questions
Your questions, answered. Here's what you need to know about enterprise blockchain development.
A public blockchain (like Bitcoin) is open to anyone, permissionless, and transparent. A private blockchain is a permissioned, invitation-only network where participants are known and vetted. This provides enterprises with control over who can join the network, what they can see, and what they can transact, ensuring higher security, privacy, and scalability.
The choice depends on your specific use case. Hyperledger Fabric is highly modular and excellent for supply chain and other industries requiring versatile permission structures. R3 Corda is purpose-built for finance and regulated industries, with a strong focus on privacy. We provide expert consultation to help you select the optimal platform for your needs.
A Proof of Concept (PoC) can typically be developed in 6-8 weeks. A full-scale, production-ready enterprise solution can take anywhere from 4 to 9 months, depending on the complexity, number of integrations, and scope of the dApps being built.
Our security strategy is multi-layered. It starts with a secure architecture design, followed by writing robust, audited smart contracts. We implement stringent, role-based access controls, conduct rigorous penetration testing, and follow best practices for node and key management to create a highly secure enterprise environment.
Absolutely. This is a core part of our service. We build custom APIs for seamless integration with your existing enterprise systems (ERP, CRM). We can also develop cross-chain bridges to enable interoperability with other private or even public blockchains, creating a more connected and powerful ecosystem.
The cost is highly variable and depends on the project's complexity. A simple PoC might start in the range of $30,000-$50,000. A comprehensive, enterprise-grade solution with multiple integrations can range from $150,000 to $500,000+. We provide detailed, transparent proposals after an initial consultation to understand your specific requirements.
