A Europol officer confessed that they could not track Monero (XMR) transactions. In a webinar organized by ; Jakubcek, from Cyber Crime Unit of Europol, confessed that “we could not track Monero (XMR) transactions” Blockchain Alliance Our comment is going to focus on privacy features of Monero and other cryptocoins. However I will give a special place to Monero in this comment. What is the reason behind your choice when using a cryptocurrency? Financial freedom or privacy? If your reason is second, think again! Let’s start with the confession of Jakubcek, from the Europol. It means two things: Privacy motive behind the use of cryptocurrencies is mostly an illusion -Monero promises real anonymity. Due to the privacy features of Monero and Zcash, they have been removed from some coin exchange platforms. This is unfair! People deserve to keep their privacy. Privacy does not mean a curtain only for criminals. Authorities in Japan and South Korea forced the crypto-coin exchanges to remove coins that have privacy features against to traceability, like Zcash and Monero. Coinbase stopped selling Zcash in England. Privacy is a need for all of us, not for criminals. If anonymity features of cryptocurrencies would not be used, it could be more dangerous than conventional money. In this comment, I am going to try to uncover some unknown points of use of cryptocurrencies, then we’re going to discover the privacy features of Monero. If I would share my IBAN address publicly, people that know my IBAN account number would also know a) Which bank that I use, b) My bank account number c) Address of the bank. That is it! However, when you share your BTC address with someone, he/she can know your all transaction historyyour balancewho are the people that you sent money to or received from It sounds scary, right? Believe me, it is a fact! Let’s say some possible scenarios that you could be in: “You are travelling through parts of a country with a medium to high violent crime rate. You need to use some of your Bitcoin to pay for something. If every person you transact with knows exactly how much money you have, this is a threat to your personal physical safety. “ https://www.monero.how/why-monero-vs-bitcoin Two terms: Tainting and Fungibility “ Fungibility means that two units of a currency can be mutually substituted and the substituted currency is equal to another unit of the same size. For example, two $10 bills can be exchanged and they are functionally identical to any other $10 bill in circulation (although $10 bills have unique ID numbers and are therefore not completely fungible). Gold is probably a closer example of true fungibility, where any 1 oz. of gold of the same grade is worth the same as another 1 oz. of gold.” https://getmonero.org/resources/moneropedia/fungibility.html But, reality is different when it comes to Bitcoin: 1 BTC != 1 BTC 1 BTC is not equal to 1 BTC always… Let’s look at behind the scene: “You sell cupcakes and receive Bitcoin as payment. It turns out that someone who owned that Bitcoin before you was involved in criminal activity.  Now you are worried that you have become a suspect in a criminal case,  because the movement of funds to you is a matter of public record. You are also worried that certain Bitcoins that you thought you owned will be considered ‘tainted’ and that others will refuse to accept them as payment. “ Why do they insist so much upon an anonymous cape? Where did the concept of anonymity come from if the transactions are traceable? The answer lies in the fact that despite the possibility to link the operations to the addresses through the blockchain, the association of each address to a person or an organization is actually complex; unless there is a demonstration by the owner of the same address by mistake, omission or some type of exchange. Crawling BTC Addresses and map them with real names is so easy, if they are shared online publicly: RegEx Pattern: [13][a-km-zA-HJ-NP-Z0–9]{26,33} So need more to keep your money transaction away from anyone else. It is time to speak on Monero. Monero means “coin” in Esperanto. It is a compound word consists of the words Mono (Money) and suffix (-ero) that states the smallest part of something. The acronym of Monero is XMR. It is possible to establish a relation between Monero and Bytecoin historically. Bytecoin was the first cryptocurrency built on CryptoNote in 2012. CryptoNote had a feature even though mostly preferred by crypto coins that mind privacy, Ring-Signature. Basically Ring Signature is a method that uses the public key of a group of people to sign a transaction in the blockchain. So it is difficult to infer which one is the real owner of the transaction. After 80 percent of the coin was minted, it caused a fork from ByteCoin and so Monero debut. At the beginning of its journey, it was called BitMonero, then it started to be called as Monero by time. Advantages of Monero Monero is a cryptocurrency that promises real anonymity by keeping both sender and receiver anonymous in the blockchain. How can Monero accomplish this? First of all, Monero, as stated above, uses a method known as Ring Signature to hide the sender. Monero uses randomly selected people`s public keys to sign the transaction. So many people in the system mean more anonymity. There is an important point that can reveal the sender`s identity in the blockchain: the total amount of the transaction. Let’s say you bought a product that costs 212.25 XMR. It looks very special and unique. It is rare to see the same amount at a T time in the blockchain. This minor detail can leak your identity. To prevent this risk, Monero uses another method known as Ring-CT to hide the total amount of the transaction. When you want to make a transaction that is worth 20 USD, instead of sending it at once, Monero would send it partially like 8 XMR + 2 XMR + 6 XMR + 4 XMR Three Keys of Monero (Public Key, Private View Key, and Private Spend Key) When you create a wallet, Monero gives you three keys. Public Key is for sharing publicly. You can share this key with the ones who would send money to you. No restriction, no risks as we mentioned on Bitcoin. Feel free to share. We’re going to talk about Stealth address in a minute. : In Monero Blockchain, to hide receiver identity, Monero uses an algorithm to produce a random address known as stealth address. Because of stealth address, no one who knows your public key could not establish a relationship with your wallet by looking at transaction history in Monero blockchain. Stealth Address : You know now transactions that sent to your address are masked with stealth address in Monero blockchain. However, how your wallet can decide which transaction is related to itself? This is where the private-view key comes into play. Monero wallet can understand which transaction belongs to your wallet by using Private-View Key. It should be kept secret and should not be shared. Private-View key : This key is used to make transactions in the name of your wallet. It should be kept secret as well. It is like a private key of Bitcoin or other currencies. Private-Spend Key Some cryptocurrencies promise privacy. However, the most important point that separates Monero from others is that privacy is not an option in Monero, it is default. No one can opt-out privacy while using Monero. You could be revealed by one who can intercept on your connection. He can understand that you are connecting to the Monero network. Good news! Monero can hide your connection. So no one can understand that you are connecting to the Monero network. By using Kovri (a P2P Protocol) you can hide your connection and prevents to cover that you are connecting to the Monero network. Monero is not only a cryptocurrency, it a movement that consists of people who believe in privacy is a human right. I learned a lot about Monero from the Mastering Monero written by SerHack. The memory conveyed in the book that proves that privacy and freedom is really important than anything else: Monero was designed with an assumption that people could mine this cryptocurrency by his/her opportunities. It could be enough to use a web browser or mobile phone to mine Monero. When ASIC miners had an advantage over the usual CPU’s, this situation forced the Monero community to take action for the sake of other users. They published an update that turns advantage of ASIC`s to disadvantage.They update the Monero algorithm every six months to discourage ASICs from mine Monero.
