Permissioned Niceties

As the name suggests permissioned blockchain is called so because only the privileged ones can join it. Users can become a part of the chain with the help of a coded key or a sort of an invitation received from the masters of the given system.

In such a way not only an additional layer of security is formed, but the supervision over each of the links in the chain is provided. It can control everything — who, when, under which circumstances sees or takes this or that action.

It can also control who operates as a node and who only uses the products of the nodes' work.

Practical Applications

The number of enterprises and governments implementing smart contracts, distributed ledgers and other blockchain-based features is ever growing.

Some applications, however, are known that include: Financial transactions,Logistics,Medicine,Government,Energy supply
