Public Blockchain
Open to All
Public blockchains are like a public park—anyone can join and participate. They are open to everyone, allowing anyone to view, interact with, and verify transactions.
Decentralized
No single authority controls a public blockchain. It operates much like a town hall meeting where everyone has a voice, and decisions are made collectively by all participants.
Private Blockchain
Restricted Access
A private blockchain is more like a private club—only specific people or organizations can join. Access is restricted, and only authorized members can participate in the network.
Controlled
Unlike public blockchains, a private blockchain is managed by a single organization, similar to a company meeting where only employees are involved. This central control allows the organization to maintain oversight of the blockchain’s operations.
Key Differences
Transparency
Public blockchains are fully transparent, allowing everyone to see and verify transactions. In contrast, private blockchains limit data access, with only authorized participants able to view the information.
Speed
Due to fewer participants, private blockchains can process transactions more quickly. The controlled environment allows for faster decision-making and execution, making them more efficient in certain use cases.
