Too Long; Didn't Read
The XRP Ledger (XRPL) was the second major blockchain system and consensus mechanism that was different from Bitcoin and Litecoin. The XRPL uses the Federated Byzantine Agreement (FBA) model as its consensus algorithm. Bitcoin's maximum supply is 21 million and XRP's total supply is 100 billion. There are no rewards, no more XRP can be minted and it is also deflationary, as every transaction cost is burned/destroyed, which slowly reduces its supply. This means that the XRP network has a better, more robust and more decentralized structure.
