Public vs Private Blockchain for Enterprise Systems

Public networks

Useful when open verification, broad composability, neutral infrastructure or public digital assets matter. They require careful privacy, fee, key and dependency design.

Permissioned networks

Useful where known organisations share infrastructure, membership is controlled and governance or confidentiality requirements are strong.

Hybrid architectures

Often practical in enterprise settings: sensitive workflows remain controlled while proofs, assets or selected events use public infrastructure.

Decision criteria

Evaluate trust boundaries, write permissions, privacy, performance, interoperability, regulatory context, operational maturity and exit risk.

Avoid chain-first design

Do not select a protocol based on popularity alone. Translate business requirements into architecture criteria and compare options against them.
