History

Monero was created as an offshoot of Bytecoin, another cryptocurrency that is focused heavily on privacy and anonymity. The Monero Core Team made several changes to Bytecoin’s codebase to improve the security and privacy of the currency, including the implementation of ring signatures, stealth addresses, and the CryptoNote protocol. The team also made efforts to ensure that the development of Monero was decentralized, with multiple developers contributing to the project.

Technology

Monero uses a proof-of-work consensus algorithm, similar to Bitcoin. However, Monero’s mining algorithm, called CryptoNight, is designed to be ASIC-resistant, which means that it can be mined using consumer-grade hardware. Typically, mining cryptocurrency requires very powerful computers and well-maintained facilities, making it difficult for individuals to mine, for example, Bitcoin.

One of the key features of Monero is its privacy technology. Unlike Bitcoin, which uses a public ledger that records all transactions, Monero uses ring signatures and stealth addresses to obscure the sender, receiver, and amount of each transaction. Monero also operates on the privacy oriented CryptoNote protocol. This makes it nearly impossible for anyone to trace the flow of exchange of Monero funds. Additionally, Monero’s privacy features also prevent double-spending and protect against blockchain analysis.

Here’s a brief overview of Monero’s privacy-oriented technologies:

• Ring signatures: Monero uses ring signatures to make it difficult to trace the source of a transaction. Ring signatures are a digital protocol that conceals the identity of the original signatory person or party, by allowing multiple users to digitally add their signature. A ring signature allows a user to sign a message or transaction without revealing their identity, as it is difficult for outside observers to determine who the actual signer is.
• Stealth addresses: Monero uses stealth addresses to protect the identity of the recipient. By generating a one-time stealth address for each transaction, instead of using public addresses.
• Confidential transactions: Monero uses confidential transactions to hide the amount being transferred. This prevents the public from seeing the exact amount being transferred, which can reveal sensitive information about both the sender and receiver.
• CryptoNote: CryptoNote is the blockchain protocol that includes the above-mentioned technologies. Monero is one among several other cryptocurrencies that utilizes CryptoNote.

Use Cases

Monero has several use cases, including:

• Private transactions: As mentioned, Monero is an ideal cryptocurrency for individuals and businesses who want to keep their financial transactions private, anonymous and confidential.
• Trading: Monero is listed on many cryptocurrency exchanges, and can be traded for other cryptocurrencies or fiat currencies. Monero’s price has historically been less volatile than Bitcoin and Ethereum, but more volatile than Litecoin. Between 2017–2020, Monero’s has had an average daily price movement of approximately 3.6%. Bitcoin and Ethereum have been higher at approximately 4.5% and 5.5% respectively, and Litecoin’s has been lower, at approximately 2.5%.
• E-commerce: Like many other cryptocurrencies, Monero can be used for online shopping. As cryptocurrencies become more mainstream and widely accepted, Monero will likely be accepted at ever more E-commerce markets.
• Donations: Monero has been used as a medium for charitable donations, as it provides a way for donors to donate without revealing their identity or financial information.
