Private, Public, and Consortium Blockchains - What's the Difference?

FEB 10, 2022

Public blockchains

The term permissionless comes alongside public.  The security-oriented approach on public chains does come with trade-offs on the performance.

Private Blockchains

Private blockchains establish rules dictating who can see and write to the chain.

Consortium Blockchains

The consortium blockchain sits on the fence between public and private chains.

Some key features that all three have in common

- An append-only ledger - A network of peers - A consensus mechanism

Which is superior?

- Well-designed public chains tend to censorship-resistance, at the cost of speed and throughput. - A private chain can prioritize the system's speed. - Consortium chains mitigate some of the counterparty risks of a private chain.
