Access. You do not need permission to access the network, it is open for everyone.

Dogecoin, bitcoin, ethereum

Only those who are trusted and get the permission from the creator

Because you can hide sensitive data, which only nodes who are trusted for the network can access. Private blockchains are not required to be transparent

  1. Private or Permissions-Based blockchains are used by businesses to send, receive & track internal transactions and keep highly detailed records, as well as compartmentalise areas of a network for different users access rights. Blockchains do not have the fragilities of CRUD, and blockchain tech in one form or another is a powerful new way to manage information and how it is accessed and recorded.

  2. Public, Permission-less blockchains such as BTC & ETH do not require any central authority to authorise a new user to participate, to create an account, or to send and receive TX. No permission is ever needed from a centralised authority.

  3. Most of the tokens and coins we know in the market run on these public/permissionless chains. Ones I like include Cardano, Zilliqa, Blockstack, Ethereum [of course] and Bitcoin [naturally]. There are many more, as we know!

  4. Only users who have been issued access are allowed to join a permissioned network. This could be, for example, HR issuing you a password and a login ID when you start a new job at a new department. You now have permission to access specific parts of the network, limited to your role, that you perhaps did not have before,

  5. The transparent nature of public blockchains as well as their permissionless nature make them unsuitable for private businesses, where information and communications need to be both permissioned and secure. Permissioned blockchains therefore give companies the best of both worlds with the security and immutability of blockchain, but with the privacy and security of a centralised private network, with trusted nodes etc.
