This requirement is one of the most critical factors.
As traditional blockchains are permissionless, in the permissioned model like Hyperledger Fabric, it is of utmost importance that transactions on the network are visible to only those who are allowed to view it.
How Modern Cryptography Protects Your Transaction Data (Part 2)
Privacy and confidentiality of transactions and contracts are of absolute importance in a business blockchain.
As such, Hyperledger’s vision is to provide support for a full range of cryptographic protocols and algorithms.
It is expected that users will be able to choose appropriate modules according to their business requirements.
For example, if a business blockchain needs to be run only between already trusted parties and performs very basic business operations, then perhaps there is no need to have advanced cryptographic support for confidentiality and privacy.
Therefore, users should be able to remove that functionality (module) or replace that with a more appropriate module that suits their needs.
Similarly, if users need to run a cross-industry blockchain, then confidentiality and privacy can be of paramount importance.
Why This Matters for Blockchain Technology
In this case, users should be able to plug an advanced cryptographic and access control mechanism (module) into the blockchain (fabric), which can even allow usage of hardware of security modules (HSMs).
Also, the blockchain should be able to handle sophisticated cryptographic algorithms without compromising performance.
In addition to the previously mentioned scenarios, due to regulatory requirements in business, there should also be a provision to allow implementation of privacy and confidentiality policies in conformance with regulatory and compliance requirements.
Key Points to Remember
- Privacy and confidentiality This requirement is one of the most critical factors.
- As traditional blockchains are permissionless, in the permissioned model like Hyperledger Fabric, it is of utmost importance that transactions on the network are visible to only those who are allowed to view it.
- Privacy and confidentiality of transactions and contracts are of absolute importance in a business blockchain.

Conclusion
Privacy and confidentiality represents one of the many innovative layers that make blockchain technology so powerful and transformative. As distributed systems continue to evolve, a solid understanding of these core concepts becomes increasingly valuable — not just for developers, but for anyone building, investing in, or working alongside blockchain-powered systems.
Whether you are just starting your blockchain journey or deepening existing expertise, mastering these fundamentals gives you the tools to think clearly about decentralized systems and make smarter decisions in this rapidly evolving space.
