Nano uses lightweight representative voting and no block rewards, aligning security with the continuing usefulness of the network rather than an energy race. Nano's sustainable-security thesis is powerful: useful payment infrastructure can justify its operation without inflating supply or charging users for every transfer. ## Key numbers and facts Nano network fee **0 XNO** The protocol does not charge a transaction fee, so the receiver can receive the full XNO amount sent. Typical confirmation **~0.2 sec** Nano documentation describes typical confirmation around 0.2 seconds in normal conditions. ## What it means in practice Nano is easiest to understand as a focused digital cash network rather than a broad crypto platform. - Fast finality matters most when the receiver needs to act immediately, such as releasing a digital product, crediting a wallet, or acknowledging a tip. - A narrow payment network can be easier to explain than a general-purpose chain, but it also depends more heavily on wallets, liquidity, and merchant demand. ## Related Nano wiki links This page is part of the xno.money Nano knowledge base.
