Stellar

Stellar Lumens is an open-source cryptocurrency that enables fast and secure transfer of value across the world. It was created in 2014 and is similar to other cryptocurrencies in terms of its decentralized nature and the fact that it uses cryptography for security.

However, one main difference between Stellar and other cryptocurrencies is its unique consensus protocol, which allows transactions to be authenticated quickly without involving miners.

Unlike Bitcoin, which has a finite and numerically small supply, Stellar supply of tokens can be increased over time. This means that it can continue to be used as a robust global currency without suffering from deflationary issues that Bitcoin could potentially have when its supply reaches its upper limit.

The greatest advantage of using Stellar over other cryptocurrencies lies in its ability to process transactions very quickly and cheaply. Transactions on the network take place almost instantly due to how it works internally with the consensus protocol that does not require proof-of-work hash calculations.
