Monero comes with its own vocabulary, from ring signatures to tail emission, and the jargon can be a wall for newcomers. This glossary defines the main Monero and privacy-coin terms in plain language, grouped by topic. Each entry is short on purpose, with a link to a fuller explanation where one exists.
Use it as a quick reference. If a term makes you curious, follow its link to the dedicated guide, and if you are brand new, the first group is the place to start.
Monero basics
Start with the words that describe Monero itself. These set up everything else in the glossary: what kind of thing Monero is, the category it belongs to, and the property that makes its privacy matter for money. If you are new to the asset, read this group before the rest, because the later terms build on it.
Monero (XMR). The leading cryptocurrency focused on private and censorship-resistant transactions (source: Monero project, what is Monero). XMR is its ticker symbol. For the full picture, see what Monero is.
Privacy coin. A cryptocurrency designed to keep transaction details private by default, rather than posting the sender, receiver, and amount on a public ledger. Monero is the most prominent example.
Fungibility. The property that every unit of a currency is interchangeable with every other, so no coin is worth more or less than another (source: Monero project, fungibility). Because Monero has no traceable history, no XMR can be blacklisted, a point explored in Monero's fungibility.
Decentralized. Run by a distributed network of participants rather than a single company or authority, so no central party controls Monero or can change its rules alone. Monero is free and open-source software (source: Wikipedia, Monero).
How Monero hides a transaction
Monero makes every transaction private using several technologies working together. Each one hides a different piece: who sent the payment, who received it, and how much moved. You do not operate any of them yourself, because the wallet applies all of them automatically to every transaction you make.
Ring signature. A digital signature made by one member of a group, where it is infeasible to tell which member actually signed (source: Monero project, ring signatures). In Monero it hides the sender; more in ring signatures.
Stealth address. A one-time address the sender creates for each payment on the recipient's behalf, so the recipient's real address never appears on the blockchain. It hides the receiver; see stealth addresses.
RingCT. Short for Ring Confidential Transactions, the feature that hides transaction amounts in Monero (source: Monero project, RingCT). It has been mandatory since 2017; see RingCT explained.
Bulletproofs. A method that lets the network confirm a hidden amount is valid while keeping the proof small, which cut Monero's transaction size and fees sharply. More in how bulletproofs work.
Dandelion++. A network-layer technique that hides which node first broadcast a transaction, protecting the sender's IP address. See network privacy and Dandelion++.
Keys, seeds, and wallets
These terms cover how you hold and control Monero. Your wallet is really a set of keys, and the seed phrase is the master backup of those keys. Understanding the difference between them is what keeps your funds both usable day to day and safe from loss or theft over time.
Public and private key. A public key, or address, is what others use to pay you; the matching private key proves ownership and authorizes spending. Never share a private key with anyone.
View key and spend key. Monero gives your wallet two private keys: the view key lets someone see your incoming transactions, and the spend key lets them spend. Sharing only the view key is safe; see view and spend keys.
Seed phrase (mnemonic). The ordered list of words that is the only backup of your wallet. Whoever holds it controls the funds, so store it offline, as covered in how to store Monero safely.
Subaddress. A sub-account address derived from your main wallet, used to keep different incoming payments organized without linking them together on the blockchain.
Wallet. The software, or hardware device, that stores your keys and lets you send and receive Monero. It holds your keys, not the coins themselves, which live on the blockchain.
The network and supply
This group describes the machinery that runs Monero and issues new coins. Together these terms explain how transactions get confirmed, how the network stays decentralized without any central operator, and how Monero's supply grows in a slow, predictable way rather than through sudden scheduled events.
Node. A device running the Monero software, whose source code is public, that keeps a copy of the blockchain and relays transactions across the network (source: Monero project source repository). Running your own is the most private way to use Monero; see how to run a Monero node.
Blockchain. The shared, append-only ledger of all confirmed transactions, maintained by the network of nodes. Monero's blockchain records that transactions happened while keeping their details hidden.
Proof-of-work (RandomX). The mining process that secures Monero. Its algorithm, RandomX, is designed to run well on ordinary CPUs and resist specialized hardware, which keeps mining broadly accessible; see Monero mining explained.
Tail emission. Monero's permanent block reward of 0.6 XMR per block, in place since May 2022, which means new coins are always issued at a small, steady rate. The monetary policy is covered in Monero's tail emission.
Block reward. The new Monero paid to a miner for adding a block. It is how new coins enter circulation and how miners are compensated for the work of securing the network.
Getting and storing Monero
The last group covers how people acquire, trade, and safeguard Monero. These are practical terms you meet the moment you try to get some, and they mostly describe a trade-off between convenience on one side and privacy or self-custody on the other, which is worth keeping in mind as you choose.
Exchange. A platform where you buy or sell Monero, usually holding your coins for you and requiring identity verification. It is often the fastest way in, but not the most private, and while your coins sit there they are in the platform's custody.
Atomic swap. A trustless trade between two blockchains, such as Bitcoin for Monero, that either completes fully or reverses, with no company holding the funds. See Monero atomic swaps and DEX trading.
DEX. A decentralized exchange: a peer-to-peer marketplace where trades happen directly between users rather than through a custodial company that holds everyone's coins.
Cold storage. Keeping your private keys offline, typically on a dedicated hardware wallet, so they never touch an internet-connected computer and stay out of reach of online malware.
Self-custody. Holding your own keys instead of leaving your Monero with an exchange. It gives you full control and full responsibility, since no one can recover your funds if you lose your seed phrase.
Frequently asked questions
What is a ring signature in Monero?
A ring signature is a type of digital signature made by one member of a group, arranged so that no observer can tell which member actually signed it. In Monero, this is what hides the sender of a transaction: your real signature is mixed with several others, so the network can confirm the payment is valid without revealing which participant sent the funds. Ring signatures are one of three main technologies Monero uses to keep transactions private, alongside stealth addresses, which hide the receiver, and RingCT, which hides the amount.
What is RingCT?
RingCT, short for Ring Confidential Transactions, is the Monero feature that hides transaction amounts. Before it, the amount of a payment was visible even though the sender and receiver were protected; RingCT closed that gap. It was introduced in 2017 and became mandatory for all Monero transactions later that year, so today every Monero transaction conceals how much was sent. Together with ring signatures for the sender and stealth addresses for the receiver, it means the three key details of a payment, who, whom, and how much, are all hidden by default.
What is a stealth address?
A stealth address is a one-time address that the sender automatically creates for each payment, on the recipient's behalf. Even though you share a single public address to receive funds, every payment you get actually lands on a unique, unlinkable address on the blockchain. This means an outside observer cannot see how many payments an address has received or link them together, which is how Monero hides the receiver. You do not have to manage any of this; the wallet software handles the one-time addresses for you.
What is Monero's tail emission?
Tail emission is Monero's permanent block reward. Instead of the reward eventually dropping to zero, it settled at a fixed 0.6 XMR per block starting at the end of May 2022, and it stays there indefinitely. This keeps a small, steady stream of new coins flowing to reward miners for securing the network. Because the amount added each block is fixed while the total supply keeps growing, the rate of inflation steadily declines over time, so tail emission is a slow, predictable backdrop rather than a source of sudden supply changes.
What is the difference between a view key and a spend key?
Monero gives your wallet two private keys with different powers. The view key lets whoever holds it see the transactions your wallet has received, but nothing more. The spend key is what actually authorizes sending funds. This separation is useful: you can share your view key with an accountant or auditor so they can verify your incoming payments, without giving them any ability to move your money. Your spend key, by contrast, must always be kept secret, because anyone with it can spend your Monero.
What makes Monero fungible?
Monero is fungible because every coin is interchangeable with every other, with no way to tell them apart by history. On a transparent cryptocurrency, coins carry a visible trail, so some can be flagged as tainted and treated as less acceptable than others. Monero hides the history of every transaction, so no XMR can be traced or blacklisted, and one unit is always worth and accepted the same as any other. This is a direct consequence of Monero's mandatory privacy, and it is a property most transparent coins do not have.
Does BloFin list Monero?
BloFin offers an XMRUSDT perpetual futures contract, which lets you trade the price of Monero rather than holding the coin itself. To use it you would create a BloFin account, fund it with cryptocurrency, and open the XMRUSDT perpetual contract trading page. That is different from acquiring Monero into a wallet you control, which is what most of the terms in this glossary describe. Nothing here is a recommendation to buy, sell, hold, or trade Monero or any other asset.
