#XRPETF How XRP works. XRP Ledger is a secure and decentralised Layer 1 blockchain that is designed for the efficient tokenisation and exchange of crypto-native and real-world assets. The native token of the XRP Ledger is XRP. XRP transactions are processed by a network of validators on the XRP Ledger. Since the XRPL does not use Proof of Work (PoW), no mining is required. Instead, XRPL relies on a consensus algorithm, and XRPL’s integrity is maintained by a group of trusted nodes. Any transaction needs to be verified by at least 80% of the nodes on the network to be included in the Ledger. Anyone can become a validator, and there are more than 100 nodes operated by universities, exchanges, businesses and individuals. This list of nodes is called the unique node list (UNL).
