Monero, or XMR for short, is an open-source cryptocurrency that is safe, reliable, private, and untraceable. It can run on Windows, Mac, Linux, and FreeBSD, and is known as one of the most private cryptocurrencies. In 2018, Monero already ranked 10th in terms of trading volume, with its market value beyond 1 billion US dollars, an evidence for its great fame in this field.
By a special method in cryptography, Monero ensures that all transactions remain 100% irrelevant and untraceable. Perhaps after reading this article, you will understand why it is so special and popular in the increasingly transparent and traceable cryptocurrency circle (After all privacy comes first!).
In fact, many large cryptocurrencies in the world are not anonymous. All transactions on Bitcoin and Ethereum are made public and traceable, which means that anyone can eavesdrop on transactions flowing into and out of the wallet. That has given rise to a new type of cryptocurrency called “privacy currency”! These “privacy currencies” hide encrypted transactions by adopting specific types of passwords. One typical example is Monero, one of the largest privacy cryptocurrencies in the world.
Monero was created on April 18, 2014 under the name BitMonero, literally the combination of Bit (Bitcoin) and Monero (the “coin” in Esperanto). In five days, the community decided to change its name to Monero.
Interestingly, Monero’s creators valued personal privacy and tried to behave in a low-key manner with pseudonyms instead of the real names. It is said that the Monero major contributor’s nickname is “thankful for today”, yet this guy has gradually disappeared from public view as Monero developed day by day.
Unlike many cryptocurrencies derived from BTC, Monero is based on the CryptoNote protocol. It is also the first branch based on the Bytecoin of CryptoNote currency. Here is some information about Bytecoin: BCN, for short, is a decentralized cryptocurrency with a high degree of privacy; it has open-source codes that allow everyone to contribute to the development of the Bytecoin network; and the Bytecoin network provides global users with instant private transactions that are not traceable and at no additional cost.
Yet, as a branch of BCN, Monero outshines its parent in reputation by being different in two ways. First, Monero’s target block time was reduced from 120 seconds to 60 seconds; second, the issuance speed was cut by 50% (which reverted to 120-second residence later, with the issuance time maintained and the reward for each new block doubled). By the way, during the fork, the Monero developers also found a lot of low-quality codes and then refactored them. (That is exactly what geeks will do)
Monero’s modular code structure was also highly appreciated by Wladimir J. van der Laan, one of the core maintainers of Bitcoin.
Monero values privacy, decentralization and scalability, and there are significant algorithm differences in blockchain fuzzification, which sets it apart from its peers. How private is it? Here are more details.
1. Safe and reliable
For a decentralized cryptocurrency, decentralization means that its network is operated by users; transactions are confirmed by decentralized consensus and then recorded on the blockchain irrevocably. Monero needs no third party to guarantee the safety of funds;
2. Privacy protection
Monero confuses all transaction sources, amounts, and recipients through ring signatures, ring confidential transactions, and invisible addresses. Apart from all the advantages of a decentralized cryptocurrency, it is by no means inferior in safeguarding privacy;
3. Unable to track
The sender, the receiver and the transaction amount of all Monero transactions must be anonymous by default. The information on the Monero Blockchain cannot be matched with physical individuals or specific users, so there is no trace to track;
Everyone knows that Bitcoin’sability to process transactions has always been limited by the scalability issue; as we have mentioned before in the introduction of Bitcoin, the block size of 1MB makes things difficult. But Monero’s developers have created a system that allows the network to process more transactions when needed; what’s more, Monero does not have any “pre-set” restrictions on block size.
Of course, this also means that some malicious miners may block the system with large blocks. To prevent this from happening, Monero has worked out countermeasures: the block reward penalty of the system.
On October 18, 2018, Monero’s latest hard fork changed the consensus mechanism algorithm to CrypotoNight V8. In this hard fork, it introduced the BulletProff bulletproof protocol, which can also effectively reduce the transaction fee of miners without disclosing transactions
It is said that Monero will issue about 18.4 million XMR in around 8 years. Moreover, it eclipses its counterparts in distribution — with no pre-mining or pre-sale, all block rewards will be left to miners by means of the POW mechanism.
Here is the reward scheme of Monero in two stages:
Due to the specificity of ASICs, specially designed ASICs can usually have much higher hashrate than general CPUs, GPUs, and even FPGAs — that makes hashrate excessively centralized and makes it vulnerable to the monopoly of single centralized institutions. Yet the cryptonight algorithm used by Monero allows most CPUs and even FPGAs to get involved and get mining rewards, instead of making GPU the only one that can efficiently mine.
In other words, Monero’s core development team will modify the consensus mechanism algorithm and have a hard fork after some time to ensure its strength against ASIC and the monopoly of hashrate.
However, although Monero has been designed against ASICs to avoid centralization, nearly 43% of its hashrate is still owned by 3 mining pools; in addition, it is not a BTC-based currency, making it even harder to introduce some elements. Of course, Monero is not that newbie-friendly, and thus has not been widely accepted.
Yet each cryptocurrency has its own features. As long as Monero keeps improving its privacy, it will definitely attract increasing followers. If you are interested in Monero, welcome to CoinEx for exchange or trade.

Blockchain’s scaling solutions can be categorized into four parts:-
The first layer scaling solution supports changes in the underlying blockchain code.
For example, increasing the block size limit from 1MB to 10 MB or reducing the block creation time from 10 minutes to 5 minutes.
Any structural or fundamental change to the property of a blockchain requires the entire community to transit into a new and improved chain.
There are 3 different scaling mechanisms in First layer scaling solution:-
· Hard fork
In this article, I will focus on one of the scaling solutions of the first layer i.e Hard Fork.
But before starting this we will first understand what fork is?
“A fork can be defined as a software upgrade/ change that brings new features to blockchain technology.”
So what are the reasons behind Fork?
Since the technology is quite new and is continuously evolving, there is a need for the latest features to provide more security, speed, privacy, robustness, etc to make it more desirable. This necessity gives rise to `the software upgrade and enhancements regularly. Hence forking came into the picture to make changes into the underlying protocol.
Forking is one of the common and iterative processes of any technology which is under development.
Another reason for forking is when the community faces disagreement in protocol upgrades. Some community members especially miners and developers were so unhappy that they created rival cryptocurrency with similar base code.
The fork can further be categorized into two parts:-
1. Hard Fork
A hard fork is a permanent parting from the previous version of a blockchain. In this method, the network got upgraded to follow a new set of consensus rules and is not compatible with the older one. Thus, to verify and validate new blocks of transactions, all network participants are required to upgrade to the latest version of the software. i.e the nodes running the older version will no longer accept transactions created on the new version. These nodes disqualify all those blocks and consider them invalid if they are not been upgraded to the latest version of the protocol. This permits the user to use the new coin as well as a new blockchain.
This method creates two different versions of the blockchain
· One continues to run on an older version.
· And others follow the newly upgraded path.
Thus it gives rise to new coins with two separate ledgers. Old Currency user receives the same amount of new currency which they were having at the time of hard fork.
Thus hard forking gives rise to two conditions:
· Either one blockchain dominates.
· Or Both blockchain co-exists and operates independently.
Few hard forked cryptocurrencies are as follows:
Find the complete list of hard forked Cryptocurrency here
There are many examples of hard forks, but the most prominent one is Bitcoin/Bitcoin Cash which was a hard fork on August 1, 2017.
The idea behind this division is to scale the Bitcoin network so that more and more transactions could be added to the block.
However, this idea was not fully welcomed by the entire Bitcoin, resulting in the hard fork. During this fork, Bitcoin continued to operate with the old protocol, and Bitcoin Cash was created with larger block size.
Hard forks can be categorized into two parts:-
· Planned Hard Fork
In planned hard fork users were intimated in advance by project developers regarding protocol upgrade. Thus, this activity enjoys a high degree of consensus from the project developers and the community before the actual hard fork process occurred.
Example: Monero’s hard fork in January of 2017, New privacy feature is known as Ring Confidential Transactions (RingCT) is added.
· Contentious Hard Fork
Now consider a case when a different participant of a project i.e its developers, network users, and miners does not agree to a common solution and proceed towards fork known as Contentious hard fork. This type of forking happens when a group of community users supports major code change with the view to invent a superior blockchain than the parent one.
Bitcoin Cash is one of the popular examples of a contentious hard fork and which happened because a group of Bitcoin community users believed that by increasing the block size of Bitcoin from 1MB to 8MB would results in faster transaction processing on the network.
Reasons for Hard fork
· To enhance security.
· Enhance transaction speed.
· Improving scalability.
2. Soft Fork
A soft fork is a software upgrade that is backward compatible with earlier versions of the software i.e the underlying code has been updated but the nodes running the older version approve new version. In the soft-forked blockchain, all blocks follow both the old and the new set of consensus rule, hence it does not require nodes on the network to upgrade to maintain consensus. However, blocks that were produced by nodes that follow old consensus rules will violate the new set of consensus rules. Thus unlike hard fork where two different blockchains are created thereby resulting in the creation of new cryptocurrency, the soft fork allows new blocks to be added to the blockchain would be approved by older nodes. Once the majority of users recognized and adopted the new set of consensus rules, the older network will be discarded, and the new blockchain will then be termed as a true’ blockchain. The shared blockchain history will remain the same until the fork.
Examples of soft forks:
· Bitcoin Improvement Proposal (BIP) 66: This was implemented as a soft fork on Bitcoin’s signature validation
· Pay to Script Hash (P2SH): This soft fork resulted in multi-signature addresses on the Bitcoin network
Examples of Hard Fork:-
In the year 2018 Bitcoin Cash further divided into two cryptocurrencies:
o Bitcoin Cash
o Bitcoin SV
Advantages of Bitcoin cash:-
· Bitcoin Cash supports block size which is eight times bigger than a Bitcoin block.
· BCH can handle more transactions per second –Thus more people can use BCH at the same time
· It has cheaper transaction fee- Around $0.20 per transaction
· BCH has faster transfer times-It takes 10 minutes to verify a Bitcoin transaction.
Litecoin is a peer-to-peer cryptocurrency and open-source software project, Litecoin was an early bitcoin spinoff and is started in October 2011. It is very similar to Bitcoin.
Three benefits of Litecoin are as follows:
o Transaction confirmation time is faster -10 minutes per transaction in BTC whereas 2.5min in LiteCoin. This difference in confirmation time makeS Litecoin famous among merchants and e-commerce stores.
o Increased storage efficiency-due to script usage in LTC proof-of-work algorithm
o More coins to reward miners (84mn to be distributed total compared to 21mn BTC).

" And by the way, I think we can successfully make Zcash too traceable for criminals like WannaCry, but still completely private & fungible. …"Ethereum's track record of immutability is also poor. Ethereum was supposed to be an immutable blockchain ledger, however after the DAO hack this proved to not be the case. A 2016 article on Saintly Law summarised the problematic nature of Ethereum's leadership and blockchain intervention:
" Many ethereum and blockchain advocates believe that the intervention was the wrong move to make in this situation. Smart contracts are meant to be self-executing, immutable and free from disturbance by organisations and intermediaries. Yet the building block of all smart contracts, the code, is inherently imperfect. This means that the technology is vulnerable to the same malicious hackers that are targeting businesses and governments. It is also clear that the large scale intervention after the DAO hack could not and would not likely be taken in smaller transactions, as they greatly undermine the viability of the cryptocurrency and the technology."Monero provides Fungibility and Privacy in a Cashless World
"Imagine 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."This lack of fungibility means that certain businesses will be obligated to avoid accepting BTC that have been previously used for purposes which are illegal, or simply run afoul of their Terms of Service. Currently some large Bitcoin companies are blocking, suspending, or closing accounts that have received Bitcoin used in online gambling or other purposes deemed unsavory by said companies. Monero has been built specifically to address the problem of traceability and non-fungibility inherent in other cryptocurrencies. By having completely private transactions Monero is truly fungible and there can be no blacklisting of certain XMR, while at the same time providing all the benefits of a secure, decentralized, permanent blockchain.
"A lack of fungibility means that when sending or receiving funds, if the other person personally knows you during a transaction, or can get any sort of information on you, or if you provide a residential address for shipping etc. – you could quite potentially have them use this against you for personal gain"For those that wish to seek more information about why Monero is a superior form of money, read The Merits of Monero: Why Monero Vs Bitcoin over on the Monero.how website.
All private transactions, More tested privacy tech, No tax on miners to pay investors, No high inflation... better investment.John McAfee, arguably cryptocurrency's most controversial character at the moment, has publicly supported Monero numerous times over the last twelve months(before he started shilling ICOs), and has even claimed it will overtake Bitcoin.
"Monero is a really good one. Monero is an incredible currency, it's completely private."There is a common belief that most of the money in cryptocurrency is still chasing the quick pump and dumps, however as the market matures, more money will flow into legitimate projects such as Monero. Monero's organic growth in price is evidence smart money is aware of Monero and gradually filtering in.
"In Bitcoin, the main chain is constrained and fees are ludicrous. This results in users being pushed to second layer stuff (e.g. sidechains, lightning network). Users do not have optionality in Bitcoin. In Monero, the goal is to make the main-chain accessible to everyone by keeping fees reasonable. We want users to have optionality, i.e., let them choose whether they'd like to use the main chain or second layer stuff. We don't want to take that optionality away from them."When the Spagni CNBC video was recently linked to the Monero subreddit, it was met with lengthy debate and discussion from both users and developers. u/ferretinjapan summarised the issue explaining:
"Monero has all the mechanisms it needs to find the balance between transaction load, and offsetting the costs of miner infrastructure/profits, while making sure the network is useful for users. But like the interviewer said, the question is directed at "right now", and Fluffys right to a certain extent, Monero's transactions are huge, and compromises in blockchain security will help facilitate less burdensome transactional activity in the future. But to compare Monero to Bitcoin's transaction sizes is somewhat silly as Bitcoin is nowhere near as useful as monero, and utility will facilitate infrastructure building that may eventually utterly dwarf Bitcoin. And to equate scaling based on a node being run on a desktop being the only option for what classifies as "scalable" is also an incredibly narrow interpretation of the network being able to scale, or not. Given the extremely narrow definition of scaling people love to (incorrectly) use, I consider that a pretty crap question to put to Fluffy in the first place, but... ¯_(ツ)_/¯"u/xmrusher also contributed to the discussion, comparing Bitcoin to Monero using this analogous description:
"While John is much heavier than Henry, he's still able to run faster, because, unlike Henry, he didn't chop off his own legs just so the local wheelchair manufacturer can make money. While Morono has much larger transactions then Bitcoin, it still scales better, because, unlike Bitcoin, it hasn't limited itself to a cripplingly tiny blocksize just to allow Blockstream to make money."Setting up a wallet can still be time consuming
Last year Bitfury’s multidisciplinary Blockchain specialists announced the possibility of revealing the identities of more than 16% of all owners of Bitcoin addresses. Several years ago, a team of CryptoLux developers, having conducted a study of transaction privacy on the Bitcoin network, concluded that 60% of all addresses can be deanonymized. Summarizing all this, it’s worth highlighting three existing methods that can successfully deanonymize private transactions.submitted by Stealthex_io to StealthEX [link] [comments]
ClusteringThe easiest way to cluster (link Bitcoin addresses) is by analyzing transactional networks. In other words, this is a method that allows finding several inputs combined in one transaction. The second clustering method is “distribution analysis”. It allows calculation the percentage of cryptocurrency at the certain address that comes from another specific address and it becomes clear whether these addresses are connected by one direct transaction or a chain of transactions or not.
Graph analysisIt consists of quantitative and temporal analyzes. Quantitative analysis studies not certain transactions, but amounts. Time analysis tracks specific periods.
Memory Pool MethodWhen a transaction is made through the user’s wallet, the input nodes send information about the transaction to the Blockchain network. The purpose of this method is to identify the set of input nodes through the wallet and the user. In this case, the IP address of the client can be associated with its transactions. There are certain private cryptocurrency-leaders which are popular and trusted among users. Using one feature-privacy, they have different ways of functioning.
Basic principles of work: anonymous cryptocurrencies (Monero, Dash, Zcash)
MoneroThe platform focuses on privacy and decentralization. The coin uses three levels of protection:
• Ring signatures, that hide the origin of the sender by mixing the user’s address with the addresses of other group members. • Ring confidential transactions, which hide the amount of the transaction. • Stealth addresses, that allow a user to hide the recipient’s address.
Such way guarantees the privacy of the sender and the recipient. Monero can be bought on Poloniex, Bitfinex, Livecoin, and Kraken crypto exchanges. It is possible to store Monero via an online wallet. More secure is its computer wallet. Due to its privacy, the popularity of the coin is expected to grow, so it makes sense to add a coin to an investment portfolio.
• Increased privacy. Cryptocurrency is suitable for those who are afraid of deanonymizing network transactions. • Unlimited and difficult mining. • It takes less time to find blocks. • Resistance to the centralization of mining capacities.
• Resources. All currency protection technologies require impressive machine performance for normal operation. The Monero block size is constantly growing, and this requires additional resources of network participants. • The popularity in the dark web leads to problems in working with regulatory authorities, exchanges often delist it. Speaking of reputation, Monero’s reputation is far from the best. The coin is often used on the dark web as payment for various illegal services. It happens to almost all crypto coins that provide privacy. • Large transaction sizes. Since Monero Blockchain is five times larger than the Bitcoin Blockchain in terms of one transaction. • Problems with scalability.
DashThe Dash platform is a classic decentralized Blockchain-based payment system and the most technologically advanced cryptocurrency. It implements multi-off-chain money transfers without loss of reliability and overall security of the Blockchain. Its confidentiality is rather an additional option that can be used optionally. In the case of anonymity, it is possible to send a hidden transaction, but at a more expensive cost, which also requires additional time. Dash developed a hashing algorithm with eleven cryptographic functions-X 11 for the first time. The coin developers have released apps for other platforms. Today it is possible to use Dash for IOS, Zeal for Linux, LovelyDocs for Android and Velocity for Windows.
As well known, the CoinJoin is an anonymization method for crypto transactions, which is used by Dash as an improved version called the PrivateSend. Its mixing sessions are limited to 1,000 DASH for each session and will require multiple mixing sessions to anonymize a large amount of money.
• High transaction speed. It is achieved via InstantX technology, which enables the confirmation of operations in less than 4 seconds. • Law transaction fees. • Energy consumption. Unlike Monero, it does not require a lot of power or high commission costs.
• “Transparency” of the network. Without triggering the “mixing” mechanism, the directions of transactions and their balances are publicly visible to everyone. • Lack of proper cryptographic technologies that provide privacy, but can provide a sufficiently high level of protection. • Transaction visibility to the founders and the team.
ZcashAn open-source decentralized cryptocurrency that provides users with maximum privacy. Zcash is the first private cryptocurrency, using cryptographic protocol zk-SNARKS, a zero-knowledge security layer. It allows users to make hidden and open transactions.
Mathematically guaranteed privacy is something cryptocurrency can not be proud of. This fact makes the currency specific. All Zcash coins are identical, it means that interchangeable coins do not contain information about past use created. In this regard, the connection of coins with their history on the Blockchain is broken, which makes them universal and identical to each other. Zcash blocks are generated 4 times faster than Bitcoin. The currency trades on Huobi, Bitfinex and Binance exchanges, and after purchase, it can be stored on the exchange’s internal wallet, as well as transferred to Jaxx, Cryptonator and Coinomi multi-currency wallets. Coins can also be stored on hardware wallets like Ledger and Trezor.
• Privacy. Since no information except the time stamp, is recorded in the Blockchain, transactions cannot be tracked, and the identity of the sender and recipient is almost impossible to establish. • Interchangeability. Due to interchangeability, all coins have a “clean” history. This means that it is practically impossible to determine which transactions coin was used. • Security. Lack of information about user keys, which protects user wallets and the network.Mining energy efficiency. Zcash mining hardware consumes less electricity than Bitcoin mining ASICs. • The difficulty of mining. Zcash is beneficial for those who want to get coins for block creation. Bitcoin mining becomes more and more complicated, so miners cannot earn enough money via their computers with high capacity.
• 6 users can decide to leave the transferred data completely open. • It takes a lot of calculations to complete a transaction. • Insecurity. There are fears that the system could be hacked, or users may accidentally open the data. • Legally ZCash is supported only by Linux, however, it provides users with wallets for other platforms: Jaxx, Ledger, Trezor, Trust, Zecwallet, Ibitcome, Exodus, Guarda, Coinomi, Cobowallet, and Bitgo.
Private cryptocurrencies are necessary for anyone who values the privacy and confidentiality of financial transactions. Privacy can generate more value, than danger, as Eric Hughes says: “Privacy is necessary for an open society in the electronic age. Privacy is not secrecy. A private matter is something one doesn’t want the whole world to know, but a secret matter is something one doesn’t want anybody to know. Privacy is the power to selectively reveal oneself to the world”.
