Many cryptocurrencies have launched in recent years. However, it’s not often that we come across a cryptocurrency with a focus on privacy and censorship-resistant transactions. In fact, Monero (XMR) is the first altcoin cryptocurrency to provide untraceable transactions.

According to Monero, the cryptocurrency has integrated cryptography to ensure that all transactions remain 100% untraceable while maintaining transparency about the Monero XMR coin.

Coindirect delves into Monero (XMR) and everything you need to know about it.


About Monero XMR: What is Monero and what does it mean?

In mid-2012, Bytecoin was launched with the implemented of CryptoNote – an application layer protocol, similar to that which runs Bitcoin, for decentralised cryptocurrencies. After the founder proposed changes, controversy and disagreements sparked within the Bytecoin community. As a result, the Bytecoin blockchain was forked; calling the new forked coins in the new chain ‘Bitmonero’.

Bitmonero was then renamed ‘Monero’, which essentially means “coin” in Esperanto. Within this new blockchain, a Monero block can be minded and added every 2-minutes.

Launched in 2014, Monero XMR is an open-source cryptocurrency that focuses on fungibility and decentralisation.

By using an enormously complex public ledger, nobody will be able to broadcast or send transactions. At the same time, no external observers will be able to tell the source, amount or destination of the transaction. This is, essentially, the core use case of Monero. However, Monero does also have selective transparency, which allows users to make particular transactions visible if desired.

Monero is also based on an application level cryptographic privacy-focused protocols known as ‘Ring Signatures’ and ‘Ring Confidential Transactions’ (RCT), as well as ‘stealth addresses’.

Since the introduction of ‘Monero’, several improvements have been made. These improvements include:

  • The migration of the blockchain to a different database structure to bring forth enhanced efficiency, seamless use and versatility.
  • The introduction to minimum ring signature sizes in order to ensure private transactions by mandate.
  • The implementation of RingCT to hide transaction amounts.
  • Heightening security.


Monero Privacy Explained…

Ring Signatures are essentially digital signatures where several transactions are signed. Of course, no user will know who the signer of the transaction is.

How it works is that a sender will generate a one-time spend key. The recipient will be able to detect and spend money based on the key generated. One key image is obtained from each expenditure spent on the blockchain, in order to solve the double spending problem – the initial aim of Satoshi Nakamoto in creating the Bitcoin blockchain.

The sender can, however, divulge information to miners to validate transactions as authentic without alerting the public.

Stealth addresses – also commonly referred to as a ‘one-time public key’ – are what makes the recipient incognito. It prevents the linking of recipient funds to their wallet – the address can be validated by a 3rd party to prove that the transaction did, in fact, happen. This means that the sender shares their public view key.

Recipients will receive their funds through their wallet private view key. Once it is received in the wallet, a single-use private key will be developed. Note that private view keys are used to scan the blockchain. Following this, recipients can use their private spend key to spend these fund, without a public connection to the recipient, sender or amount.


How Monero Transactions Work

How Monero Transactions Work

Monero Bitcointalk provides a good example in explaining how Monero XMR transactions work – the numbers match with the correlating picture:

“Bob decides to spend an output, which was sent to the one-time public key. He needs Extra (1), TxOutNumber (2), and his Account private key (3) to recover his one-time private key (4). When sending a transaction to Carol, Bob generates its Extra value by random (5). He uses Extra (6), TxOutNumber (7) and Carol’s Account public key (8) to get her Output public key (9).

In the input, Bob hides the link to his output among the foreign keys (10). To prevent double-spending he also packs the Key image, derived from his One-time private key (11). Finally, Bob signs the transaction, using his One-time private key (12), all the public keys (13) and Key Image (14). He appends the resulting Ring Signature to the end of the transaction (15).”


What is Monero Mining? How Does Monero Mining Work? Can you mine Monero with a GPU?

These are all common questions asked by XMR holders looking to increase their return on investment. Other than using a cryptocurrency wallet, P2P or exchange, it is possible to mine Monero.

According to Coin Central, a challenge faced by Monero mining was pool centralization; prompted by a threat of secret ASIC mining that was more efficient than GPU Monero mining. This is due to a fork away from ASIC miners; resulting in a drop by more than 50% in the original Monero (XMR) pools hash rate. Monero still remains a GPU-mineable cryptocurrency.


Why Buy Monero (XMR)?

Monero has promised 4 key exclusivities to its community – security, privacy, untraceable and fungibility. Here’s why many altcoin buyers are choosing Monero:

  1. Untraceable
    The addresses used to send and receive XMR, as well as the XMR amount transacted, are muddled by default. This means that all transactions on the Monero blockchain cannot be traced back to a real-life identity.
  2. Secure
    As a decentralized cryptocurrency, Monero is operated by a network of users and transactions are confirmed by a distributed consensus without the need for any third-parties. Here, all transactions are permanently recorded on the blockchain.
  3. Private
    Ring signatures, ring confidential transactions (RCT) and stealth addresses are used to blur out the amount, origin and destination of XMR transactions. This ensures 100% privacy for the Monero community.
  4. Fungible
    What makes Monero fungible is that it is private by default. As a result, it is impossible for Monero XMR to be blacklisted by vendors or cryptocurrency exchanges, due to their association in previous transactions.
