Permissionless blockchain refers to one in which users don’t require permission from any other participant on the network to carry out specific actions. The blockchain design also applies to actions such as joining the network. It is quite clear that permissionless blockchains have public availability with better levels of transparency and decentralization. Permissionless blockchains ensure equal distribution of voting power among all network participants. Litecoin and Bitcoin are prominent and popular examples of permissionless blockchains.
