When the XRP Ledger began, 100 billion XRP were created, and no more XRP will ever be created. (Each XRP is subdivisible down to 6 decimal places, for a grand total of 100 quadrillion of XRP.) The available supply of XRP decreases slowly over time as small amounts are destroyed to pay transaction costs.
The primary function of XRP is to protect the Ripple protocol against denial-of-service (DoS) spam attacks. Since the Ripple protocol is based around a shared ledger of accounts, a malicious attacker could create large amounts of ledger spam (such as fake accounts) and transaction spam (such as fake transactions) in an attempt to overload the protocol. This could cause the size of the ledger to become unmanageable and interfere with the protocolu2019s ability to quickly settle legitimate transactions.
