Use Public Chains for Trustless Transparency
Public blockchains? Use them when you need trustless transparency—proving diamond origins to skeptics or running DeFi without middlemen.
Private chains? They’re for high-stakes speed demons: moving patient data between hospitals or settling $10M bank transfers confidentially.
Your choice hinges on four questions:
- Who do you trust? (Strangers or vetted partners?)
- What must stay hidden? (Everything public or encrypted details?)
- How fast is fast enough? (Minutes or milliseconds?)
- Who gets access? (Open ecosystem or approved players?)
The future isn’t public vs. private—it’s hybrids. We’re already merging them: zero-knowledge proofs let private chains prove compliance on Bitcoin, while keeping data locked.
A shipping client verifies cargo temperatures publicly but hides supplier contracts privately—same chain.
Enterprises need scalpels, not hammers. Build chains that solve real problems, not satisfy crypto Twitter debates.

Choose Private Chains for Speed and Security
When clients ask whether the use of blockchain will be public or private, I always say it depends on what you’re trying to protect or prove. If your business is dealing with sensitive data, such as patient records or financial transactions, then a private blockchain provides you with control, security, and the compliance guardrails needed. But I’ve watched public blockchains excel in areas where transparency was not optional—like the verification of digital ownership or the development of decentralized apps. Sure, public chains are slower and pricier at times, but the trust they build can sometimes be worth it.
My general bias is to go private for enterprise operations and public when the ultimate goal is user trust at scale. The trick is knowing where flexibility and transparency matter more than each other, or not. There is no “must” or “must not”—just smart alignment with your business goals.

Align Blockchain Choice with Business Goals
Public blockchains are great for transparency and trustless environments, like NFTs or global remittance tools. However, for enterprises, especially in finance or ticketing, private blockchains often make more sense. We recommend private or permissioned blockchains when compliance, data privacy, or transaction speed is a concern. The choice should come down to the business model and regulatory landscape—there’s no one-size-fits-all solution. The key is designing around real-world constraints, not just hype.

Private Chains for Compliance and Privacy
In my experience working with enterprise clients exploring blockchain, the public vs. private debate isn’t about which is better—it’s about alignment with business objectives, compliance needs, and the ecosystem you’re operating in.
For instance, I’ve seen private blockchains work incredibly well in industries where data privacy, regulatory compliance, and control over access are non-negotiable—think healthcare, finance, or supply chain logistics. One client in the pharmaceutical space used a private Hyperledger Fabric network to track drug provenance. The controlled environment gave them the auditability they needed without exposing sensitive data, and integration with legacy systems was smoother since they had more governance over the chain’s rules and participants.
On the other hand, public blockchains make sense when transparency, decentralization, and broad network effects are essential. I’d recommend public chains in scenarios like tokenizing assets, building DeFi solutions, or creating digital identity layers that need to interoperate across platforms. A startup I advised chose Ethereum for a loyalty rewards system because they wanted users to truly own their rewards and potentially trade them. That wouldn’t have had the same value if it were locked in a closed system.
The real key is this: private blockchains offer control; public blockchains offer reach. Enterprises that need internal efficiency, trusted partnerships, and granular access control will lean private. But if you’re trying to build something composable, user-centric, and future-proof in an open ecosystem, public chains are where the innovation tends to happen.
Often, the best solution isn’t choosing one over the other, but designing hybrid models that leverage the strengths of both.

Control and Trust Determine Blockchain Choice
From an enterprise perspective, the choice between public and private blockchains ultimately comes down to control, scalability, and trust requirements.
Private blockchains tend to be more suitable for most business use cases. They offer greater control over who can access and validate transactions, which is crucial when dealing with sensitive financial data or operating within regulated industries. For example, if you’re integrating blockchain into an ERP system like NetSuite to enhance supply chain traceability or automate contract settlements, you would typically want that data shared only with authorized parties. Private chains are also more easily scalable and customizable to internal workflows.
Public blockchains do have their place, particularly when transparency and broad participation are essential, such as in tokenized assets or cross-border payments. However, they come with challenges related to data privacy, transaction speed, and governance that most mid-sized businesses are not equipped to handle.
In summary, for most enterprise use cases, private blockchains are the more practical option.

Match Blockchain to Business Needs
For most enterprise use cases, I lean toward private blockchains. They offer more control, better privacy, and faster transaction speeds—all critical for internal processes like supply chain tracking or intercompany settlements.
Public blockchains make sense when transparency and decentralization are core to the product. Think NFTs, open finance, or anything user-facing where trustless verification matters.
If compliance, performance, or data sensitivity are key, go private. If community trust and openness are the priority, public wins. It’s not one-size-fits-all—match the chain to the business goal.
