With the need for privacy and confidentiality, a major focus is on developing private distributed ledgers that can be used within a group of trusted participants.
As public blockchains, due to their open and comparatively less secure nature, are not suitable for industries such as finance, medicine, and law, private blockchains hold the promise to address this limitation and bring end users one step closer to reaping the benefits of blockchains while meeting all security and privacy requirements.
When Enterprise Needs Controlled Access (Part 2)
Public blockchains are less secure because generally, they do not provide privacy and confidentiality services.
Private blockchains allow the participants or a subset of participants to be in full control of the system, thus making it desirable for use in finance and other industries where privacy and control are required.
Ethereum can be used in both private and public modes, whereas there are a few projects that have been developed solely as private blockchains, such as Hyperledger and Corda.
Why This Matters for Blockchain Technology
Understanding Private blockchains is not just an academic exercise — it has real-world implications for how blockchain systems are designed, deployed, and secured. Whether you are a developer building decentralized applications, a business leader evaluating blockchain adoption, or a curious learner exploring the technology, this knowledge provides a critical foundation.
