What it is
XRP is the native asset of the XRP Ledger, a distributed payments network designed for fast, low-cost cross-border value transfer, developed alongside Ripple Labs.
Technology & consensus
The XRP Ledger does not use mining. Servers propose candidate transaction sets and vote across rounds until a supermajority of each server's trusted validator list (UNL) agrees, closing a ledger every few seconds. The paper formalizes correctness, agreement, and utility goals and shows agreement holds when collectively-trusted subnetworks overlap sufficiently.
Token utility
XRP is the ledger's native currency: it pays transaction fees that are destroyed (anti-spam), satisfies minimum account and trust-line reserve requirements, and serves as a bridge currency for cross-currency payments.
Key risks & notes
Ripple Labs holds a large share of XRP in escrow; validator ecosystem is smaller and more centralized than major PoW/PoS chains. Note: the 2014 paper itself is hosted as historical interest and directs readers to the updated 2018 analysis (arXiv:1802.07242); XRP's regulatory status has also faced prolonged scrutiny.
