See Monero Outreach website for more information. accepting: translated: "yes" title: Instructions for the Command-Line Interface basics: The Basics basics_para1: Monero works a little differently to what you may have become accustomed to from other @cryptocurrencies. In the case of a digital currency like Bitcoin and its many derivatives merchant payment systems will usually create a new recipient @address for each payment or user. basics_para2: However, because Monero has @stealth-addresses there is no need to have separate recipient addresses for each payment or user, and a single @account address can be published. Instead, when receiving payments a merchant will provide the person paying with a "payment ID". basics_para3: "A @payment-ID is a hexadecimal string that is 64 characters long, and is normally randomly created by the merchant. An example of a payment ID is:" checking: Checking for a Payment in monero-wallet-cli checking_para1: | If you want to check for a payment using monero-wallet-cli you can use the "payments" command followed by the payment ID or payment IDs you want to check. For example: checking_para2: If you need to check for payments programmatically, then details follow the next section. receiving: Receiving a Payment Step-by-Step receiving_list1: Generate a random 64 character hexadecimal string for the payment receiving_list2: Communicate the payment ID and Monero address to the individual who is making payment receiving_list3: Check for the payment using the "payments" command in monero-wallet-cli program: Checking for a Payment Programmatically program_para1: In order to check for a payment programmatically you can use the get_payments or get_bulk_payments JSON RPC API calls. program_para2: this requires a payment_id parameter with a single payment ID. program_para3: this is the preferred method, and requires two parameters, payment_ids - a JSON array of payment IDs - and an optional min_block_height - the block height to scan from. program_para4: | An example of returned data is as follows: program_para5: It is important to note that the amounts returned are in base Monero units and not in the display units normally used in end-user applications. Also, since a transaction will typically have multiple outputs that add up to the total required for the payment, the amounts should be grouped by the tx_hash or the payment_id and added together. Additionally, as multiple outputs can have the same amount, it is imperative not to try and filter out the returned data from a single get_bulk_payments call. program_para6: Before scanning for payments it is useful to check against the daemon RPC API (the get_info RPC call) to see if additional blocks have been received. Typically you would want to then scan only from that received block on by specifying it as the min_block_height to get_bulk_payments. scanning: Programatically Scanning for Payments scanning_list1: Get the current block height from the daemon, only proceed if it has increased since our last scan scanning_list2: Call the get_bulk_payments RPC API call with our last scanned height and the list of all payment IDs in our system scanning_list3: Store the current block height as our last scanned height scanning_list4: Remove duplicates based on transaction hashes we have already received and processed contributing: translated: "yes" intro: Monero is an open-source, community-driven project.

If no one is willing to buy Monero, then it will not have any value. Monero’s price increases if demand exceeds supply, and it decreases if supply exceeds demand. q2: How can I get Monero? a2: You can buy Monero from an exchange or from an individual. Alternatively, you can try mining Monero to get coins from the block reward. q3: What is a mnemonic seed? a3: A mnemonic seed is a set of 25 words that can be used to restore your account anywhere. Keep these words safe and do not share them with someone else. You can use this seed to restore your account, even if your computer crashes. q4: How is Monero’s privacy different from other coins? a4: | Monero uses three different privacy technologies: ring signatures, ring confidential transactions (RingCT), and stealth addresses. These hide the sender, amount, and receiver in the transaction, respectively. All transactions on the network are private by mandate; there is no way to accidentally send a transparent transaction. This feature is exclusive to Monero. You do not need to trust anyone else with your privacy. q5: Why is my wallet taking so long to sync? a5: If you are running a full node locally, you need to copy the entire blockchain to your computer. This can take a long time, especially on an old hard drive or slow internet connection. If you are using a remote node, your computer still needs to request a copy of all the outputs, which can take several hours. Be patient, and if you would like to sacrifice some privacy for faster sync times, consider using a lightweight wallet instead. q6: What is the difference between a lightweight and a normal wallet? a6: For a lightweight wallet, you give your view key to a node, who scans the blockchain and looks for incoming transactions to your account on your behalf. This node will know when you receive money, but it will not know how much you receive, who you received it from, or who you are sending money to. Depending on your wallet software, you may be able to use a node you control to avoid privacy leaks. For more privacy, use a normal wallet, which can be used with your own node. q7: How is Monero different from Bitcoin? a7: Monero is not based on Bitcoin. It is based on the CryptoNote protocol. Bitcoin is a completely transparent system, where people can see exactly how much money is being sent from one user to another. Monero hides this information to protect user privacy in all transactions. It also has a dynamic block size and dynamic fees, an ASIC-resistant proof of work, and a tail coin emission, among several other changes. q8: Does Monero have a block size limit? a8: No, Monero does not have a hard block size limit. Instead, the block size can increase or decrease over time based on demand. It is capped at a certain growth rate to prevent outrageous growth. q9: What is a blockchain? a9: A blockchain is a system that stores a copy of all transaction history on the Monero network. Every two minutes, a new block with the latest transaction information is added to the blockchain. This chain allows the network to verify the amount of money accounts have and make it resilient to attacks and centralization attempts. q10: What is Kovri? a10: Kovri is an I2P router written in C++. I2P is a hidden network like Tor with several technical differences. Kovri is an independent project of Monero, but it will work with Monero and several other projects. Kovri hides the transaction broadcast, so other nodes do not know who created transactions. In adversarial conditions, Kovri can be used to hide all Monero traffic through I2P, which would prevent people from knowing Monero is being used. Kovri is currently in alpha, and it is not yet fully integrated in Monero. Learn more about Kovri at the project website. q11: What is fungibility, and why is it important? a11: Fungibility is a simple property of money such that there are no differences between two amounts of the same value. If two people exchanged a 10 and two 5’s, then no one would lose out. However, let’s suppose that everyone knows the 10 was previously used in a ransomware attack. Is the other person still going to make the trade? Probably not, even if the person with the 10 has no connection with the ransomware. This is a problem, since the receiver of money needs to constantly check the money they are receiving to not end up with tainted coins. Monero is fungible, which means people do not need to go through this effort. q12: If Monero is so private how do we know they're not being created out of thin air? a12-1: In Monero, every transaction output is uniquely associated with a key image that can only be generated by the holder of that output. Key images that are used more than once are rejected by the miners as double-spends and cannot be added to a valid block. When a new transaction is received, miners verify that the key image does not already exist for a previous transaction to ensure it's not a double-spend. a12-2: We can also know that transaction amounts are valid even though the value of the inputs that you are spending and the value of the outputs you are sending are encrypted (these are hidden to everyone except the recipient). Because the amounts are encrypted using Pedersen commitments what this means is that no observers can tell the amounts of the inputs and outputs, but they can do math on the Pedersen commitments to determine that no Monero was created out of thin air. a12-3: As long as the encrypted output amounts you create is equal to the sum of the inputs that are being spent (which include an output for the recipient and a change output back to yourself and the unencrypted transaction fee), then you have a legitimate transaction and know no Monero is being created out of thin air. Pedersen commitments mean that the sums can be verified as being equal, but the Monero value of each of the sums and the Monero value of the inputs and outputs individually are undeterminable. q13: Is Monero magic and protect my privacy no matter what I do ? a13: Monero is not magic. If you use Monero but give your name and address to another party, the other party will not magically forget your name and address. If you give out your secret keys, others will know what you've done. If you get compromised, others will be able to keylog you. If you use a weak password, others will be able to brute force your keys file. If you backup your seed in the cloud, you'll be poorer soon. q14: Is Monero 100% anonymous ? a14: There is no such thing as 100% anonymous. If nothing else, your anonymity set is the set of people using Monero. Some people don't use Monero. Monero may also have bugs. Even if not, ways may exist to infer some information through Monero's privacy layers, either now or later. Attacks only get better. If you wear a seatbelt, you can still die in a car crash. Use common sense, prudence and defense in depth. mining: translated: "yes" intro1: Monero is a cryptocurrency that relies on proof-of-work mining to achieve distributed consensus.

For a listing, see the transact_para2: Merchants page. what-is-monero: translated: "yes" need-to-know: What you need to know leading: Monero is the leading cryptocurrency with a focus on private and censorship-resistant transactions. leading_para1: Most existing cryptocurrencies, including Bitcoin and Ethereum, have transparent blockchains, meaning that transactions are openly verifiable and traceable by anyone in the world. Furthermore, sending and receiving addresses for these transactions may potentially be linkable to a person's real-world identity. leading_para2: Monero uses cryptography to shield sending and receiving addresses, as well as transacted amounts. confidential: Monero transactions are confidential and untraceable. confidential_para1: Every Monero transaction, by default, obfuscates sending and receiving addresses as well as transacted amounts. This always-on privacy means that every Monero user's activity enhances the privacy of all other users, unlike selectively transparent cryptocurrencies (e.g. Zcash). confidential_para2: Monero is fungible. By virtue of obfuscation, Monero cannot become tainted through participation in previous transactions. This means Monero will always be accepted without the risk of censorship. confidential_para3: The Kovri Project, confidential_para4: currently in development confidential_para5: ", will route and encrypt transactions via I2P Invisible Internet Project nodes. This will obfuscate a transactor's IP address and provide further protection against network monitoring." grassroots: Monero is a grassroots community attracting the world's best cryptocurrency researchers and engineering talent. grassroots_para1: Over grassroots_para2: 500 developers grassroots_para3: have contributed to the Monero project, including 30 core developers. Forums and chat channels are welcoming and active. grassroots_para4: Monero's Research Lab, Core Development Team and Community Developers are constantly pushing the frontier of what is possible with cryptocurrency privacy and security. grassroots_para5: Monero is not a corporation. It is developed by cryptography and distributed systems experts from all over the world that donate their time or are funded by community donations. This means that Monero can't be shut down by any one country and is not constrained by any particular legal jurisdiction. electronic: Monero is electronic cash that allows fast, inexpensive payments to and from anywhere in the world. electronic_para1: There are no multi-day holding periods and no risk of fraudulent chargebacks. It is safe from ‘capital controls’ - these are measures that restrict the flow of traditional currencies, sometimes to an extreme degree, in countries experiencing economic instability. videos: Monero Videos (English) about: translated: "yes" history: A Brief History history_para1: Monero was launched in April 2014. It was a fair, pre-announced launch of the CryptoNote reference code. There was no premine or instamine, and no portion of the block reward goes to development. See the original Bitcointalk thread history_para2: here. history_para3: The founder, thankful_for_today, proposed some controversial changes that the community disagreed with. A fallout ensued, and the Monero Core Team forked the project with the community following this new Core Team. This Core Team has provided oversight since. history_para4: Monero has made several large improvements since launch. The blockchain was migrated to a different database structure to provide greater efficiency and flexibility, minimum ring signature sizes were set so that all transactions were private by mandate, and RingCT was implemented to hide the transaction amounts. Nearly all improvements have provided improvements to security or privacy, or they have facilitated use. Monero continues to develop with goals of privacy and security first, ease of use and efficiency second. values: Our Values values_para: Monero is more than just a technology. It’s also what the technology stands for. Some of the important guiding philosophies are listed below. security: Security security_para: Users must be able to trust Monero with their transactions, without risk of error or attack. Monero gives the full block reward to the miners, who are the most critical members of the network who provide this security. Transactions are cryptographically secure using the latest and most resilient encryption tools available. privacy: Privacy privacy_para: Monero takes privacy seriously. Monero needs to be able to protect users in a court of law and, in extreme cases, from the death penalty. This level of privacy must be completely accessible to all users, whether they are technologically competent or have no idea how Monero works. A user needs to confidently trust Monero in a way that this person does not feel pressured into changing their spending habits for risk of others finding out. decentralization: Decentralization decentralization_para: Monero is committed to providing the maximum amount of decentralization. With Monero, you do not have to trust anyone else on the network, and it is not run by any large group. An accessible “Proof of Work” algorithm makes it easy to mine Monero on normal computers, which makes it more difficult for someone to purchase a large amount of mining power.

Below you'll find the work of our very own Monero Research Lab, with more papers to come. mrl_papers: Monero Research Lab Papers (English) abstract: Abstract introduction: Introduction read-paper: Read Paper mrl1: A Note on Chain Reactions in Traceability in CryptoNote 2.0 mrl1_abstract: This research bulletin describes a plausible attack on a ring-signature based anonymity system. We use as motivation the cryptocurrency protocol CryptoNote 2.0 ostensibly published by Nicolas van Saberhagen in 2012. It has been previously demonstrated that the untraceability obscuring a one-time key pair can be dependent upon the untraceability of all of the keys used in composing that ring signature. This allows for the possibility of chain reactions in traceability between ring signatures, causing a critical loss in untraceability across the whole network if parameters are poorly chosen and if an attacker owns a sufficient percentage of the network. The signatures are still one-time, however, and any such attack will still not necessarily violate the anonymity of users. However, such an attack could plausibly weaken the resistance CryptoNote demonstrates against blockchain analysis. This research bulletin has not undergone peer review, and reflects only the results of internal investigation. mrl2: Counterfeiting via Merkle Tree Exploits within Virtual Currencies Employing the CryptoNote Protocol mrl2_abstract: On 4 September 2014, an unusual and novel attack was executed against the Monero cryptocurrency network. This attack partitioned the network into two distinct subsets which refused to accept the legitimacy of the other subset. This had myriad effects, not all of which are yet known. The attacker had a short window of time during which a sort of counterfeiting could occur, for example. This research bulletin describes deficiencies in the CryptoNote reference code allowing for this attack, describes the solution initially put forth by Rafal Freeman from Tigusoft.pl and subsequently by the CryptoNote team, describes the current fix in the Monero code base, and elaborates upon exactly what the offending block did to the network. This research bulletin has not undergone peer review, and reflects only the results of internal investigation. mrl3: Monero is Not That Mysterious mrl3_abstract: Recently, there have been some vague fears about the CryptoNote source code and protocol floating around the internet based on the fact that it is a more complicated protocol than, for instance, Bitcoin. The purpose of this note is to try and clear up some misconceptions, and hopefully remove some of the mystery surrounding Monero Ring Signatures. I will start by comparing the mathematics involved in CryptoNote ring signatures (as described in [CN]) to the mathematics in [FS], on which CryptoNote is based. After this, I will compare the mathematics of the ring signature to what is actually in the CryptoNote codebase. mrl4: Improving Obfuscation in the CryptoNote Protocol mrl4_abstract: We identify several blockchain analysis attacks available to degrade the untraceability of the CryptoNote 2.0 protocol. We analyze possible solutions, discuss the relative merits and drawbacks to those solutions, and recommend improvements to the Monero protocol that will hopefully provide long-term resistance of the cryptocurrency against blockchain analysis. Our recommended improvements to Monero include a protocol-level network-wide minimum mix-in policy of n = 2 foreign outputs per ring signature, a protocol-level increase of this value to n = 4 after two years, and a wallet-level default value of n = 4 in the interim. We also recommend a torrent-style method of sending Monero output. We also discuss a non-uniform, age-dependent mix-in selection method to mitigate the other forms of blockchain analysis identified herein, but we make no formal recommendations on implementation for a variety of reasons. The ramifications following these improvements are also discussed in some detail. This research bulletin has not undergone peer review, and reflects only the results of internal investigation. mrl5: Ring Signature Confidential Transactions mrl5_abstract: This article introduces a method of hiding transaction amounts in the strongly decentralized anonymous cryptocurrency Monero. Similar to Bitcoin, Monero is a cryptocurrency which is distributed through a proof of work “mining” process. The original Monero protocol was based on CryptoNote, which uses ring signatures and one-time keys to hide the destination and origin of transactions. Recently the technique of using a commitment scheme to hide the amount of a transaction has been discussed and implemented by Bitcoin Core Developer Gregory Maxwell. In this article, a new type of ring signature, A Multi-layered Linkable Spontaneous Anonymous Group signature is described which allows for hidden amounts, origins and destinations of transactions with reasonable efficiency and verifiable, trustless coin generation. Some extensions of the protocol are provided, such as Aggregate Schnorr Range Proofs, and Ring Multisignature. The author would like to note that early drafts of this were publicized in the Monero Community and on the bitcoin research irc channel. Blockchain hashed drafts are available in [14] showing that this work was started in Summer 2015, and completed in early October 2015. An eprint is also available at http://eprint.iacr.org/2015/1098. mrl6: An Efficient Implementation of Monero Subaddresses mrl6_abstract: Users of the Monero cryptocurrency who wish to reuse wallet addresses in an unlinkable way must maintain separate wallets, which necessitates scanning incoming transactions for each one. We document a new address scheme that allows a user to maintain a single master wallet address and generate an arbitary number of unlinkable subaddresses. Each transaction needs to be scanned only once to determine if it is destinated for any of the user’s subaddresses. The scheme additionally supports multiple outputs to other subaddresses, and is as efficient as traditional wallet transactions. mrl7: Sets of Spent Outputs mrl7_abstract: This technical note generalizes the concept of spend outputs using basic set theory. The definition captures a variety of earlier work on identifying such outputs. We quantify the effects of this analysis on the Monero blockchain and give a brief overview of mitigations. mrl8: Dual Linkable Ring Signatures mrl8_abstract: This bulletin describes a modification to Monero's linkable ring signature scheme that permits dual-key outputs as ring members. Key images are tied to both output one-time public keys in a dual, preventing both keys in that transaction from being spent separately. This method has applications to non-interactive refund transactions. We discuss the security implications of the scheme. mrl9: Thring Signatures and their Applications to Spender-Ambiguous Digital Currencies mrl9_abstract: We present threshold ring multi-signatures (thring signatures) for collaborative computation of ring signatures, present a game of existential forgery for thring signatures, and discuss uses of thring signatures in digital currencies that include spender-ambiguous cross-chain atomic swaps for confidential amounts without a trusted setup. We present an implementation of thring signatures that we call linkable spontaneous threshold anonymous group signatures, and prove the implementation existentially unforgeable. mrl10: Discrete Logarithm Equality Across Groups mrl10_abstract: This technical note describes an algorithm used to prove knowledge of the same discrete logarithm across different groups. The scheme expresses the common value as a scalar representation of bits, and uses a set of ring signatures to prove each bit is a valid value that is the same (up to an equivalence) across both scalar groups. mrl11: Compact linkable ring signatures and applications mrl11_abstract: We describe an efficient linkable ring signature scheme, compact linkable spontaneous anonymous group (CLSAG) signatures, for use in confidential transactions. Compared to the existing signature scheme used in Monero, CLSAG signatures are both smaller and more efficient to generate and verify for ring sizes of interest. We generalize the construction and show how it can be used to produce signatures with coins of different type in the same transaction. cryptonote: Cryptonote Whitepapers cryptonote-whitepaper: Cryptonote Whitepaper cryptonote-whitepaper_para: This is the original cryptonote paper written by the cryptonote team.
