• 1. The Anonymous White Paper

  ›

  In October 2013, a document titled CryptoNote v2 appeared online. It described privacy and anonymity as the most important aspects of electronic cash. The author signed the paper as Nicolas van Saberhagen, yet no one knew his true identity. This text characterized Bitcoin's traceability as a critical flaw in existing digital money systems. A forum user named thankful_for_today later implemented these ideas into a coin called BitMonero. Other community members disagreed with this direction and decided to fork the project in 2014. That split created Monero, which translates to coin in Esperanto. Both van Saberhagen and thankfull_for_today remain anonymous today.

• 2. Obfuscation By Design

  ›

  All transaction details on the Monero network are obfuscated by default. Ring signatures group a sender's outputs with other decoy outputs to create ambiguity. Encryption of transaction amounts began in 2017 with the implementation of ring confidential transactions. Developers also added zero-knowledge proofs known as Bulletproofs to guarantee a transaction occurred without revealing its value. Stealth addresses protect recipients by generating public keys untraceable to the receiver. Dandelion++ obscures the IP address of devices producing transactions through probabilistic flooding methods. These features contrast sharply with Bitcoin where all wallet balances remain transparent.

• 3. Resisting Centralized Mining

  ›

  The protocol uses RandomX to validate transactions and issue new coins to miners. This algorithm replaced CryptoNightR in November 2019 to better resist application-specific integrated circuit mining. The design allows efficient mining on consumer-grade hardware like x86 processors and GPUs. This choice opposes the centralization that ASIC mining creates for other cryptocurrencies. However, this accessibility has resulted in popularity among malware-based non-consensual miners. Some websites embedded Coinhive scripts to use visitors' CPU resources while they consumed content.

• 4. Tools For The Shadow Economy

  ›

  Darknet markets adopted Monero as a common medium of exchange after August 2016. AlphaBay permitted vendors to accept it as an alternative to Bitcoin before law enforcement took it offline in 2017. The site relaunched in 2021 with Monero as the sole permitted currency. Ransomware groups increasingly demanded payment in this currency following the Colonial Pipeline hack in May 2021. REvil removed the option of paying ransoms in Bitcoin by 2021 to demand only Monero. In the first half of 2018, Monero was used in 44% of cryptocurrency ransomware attacks according to CNBC reports.

• 5. The Hunt For Anonymity

  ›

  Researchers highlighted three major threats to user privacy in April 2017 regarding ring signature sizes. The United States Internal Revenue Service posted a $625,000 bounty in September 2020 for contractors developing tracing tools. Chainalysis and Integra FEC won the contract to build these technologies. A transaction-flooding attack model called FloodXMR appeared at the IEEE International Conference on Blockchain and Cryptocurrency in 2021. This method showed how adversaries could deanonymize new transaction inputs over time under specific assumptions about fees.

• 6. Exchanges Under Pressure

  ›

  Regulatory pressure caused exchanges in South Korea and Australia to delist Monero in late 2020. Binance delisted the asset on the 20th of February 2024 citing compliance requirements. Kraken halted all trading and deposits for users in the European Economic Area by the 31st of October 2024. Remaining balances were converted to Bitcoin after withdrawals were suspended for those regions. Europol predicted criminals would shift from Bitcoin to Monero in 2018 as authorities improved monitoring of public blockchains.
