    Monero (XMR) in a Nutshell

    Monero is a rather unique member of the cryptocurrency family thanks to its focus on privacy and absence of the traditional open blockchain network like those found on Bitcoin. It is, in a nutshell, a system that makes use of three key technologies — Ring Signature, Stealth Address and Ring CT (Confidential Transaction) — to ensure that the sender, receiver and transaction amount are concealed from view.

    On a traditional blockchain, you can freely click to see who sent any transaction, how much it was, and who the receiver is. For many this was the logical way to do things because an open book meant less suspicion of dubious activities on the network. Going into “stealth mode”, as you can choose to on some platforms, is a sure-fire way to attract raised eyebrows. Monero tried to eliminate this problem by making its transactions 100% private.

    Advantages and Disadvantages of Monero

    + Users don’t have to worry about fraudulent chargebacks or multi-day holding periods. What’s more, there are no capital controls which restrict flow for traditional currencies. The user truly is in control.

    + Protection by CryptoNote’s hashing algorithm, “CryptoNight” makes it more resistant to ASICs (but not 100% ASIC-proof). The thinking is that it would be so costly to produce an ASIC for Monero that the benefits couldn’t possibly be worth it.

    + For better or worse, privacy is more attractive to more users. Privacy has always been a hallmark of any online industry’s success. Online shopping, for instance, was never going to be a reality unless people had ways to conceal their purchase histories and keep things private.

    Monero focuses on privacy

    – On February 19th 2017, the CryptoNote currencies, including Monero, were subject to a bug that allowed for stealthy creation of an unlimited number of coins, untraceable unless the viewer, too, knew about the flaw and what to look for. Fortunately, after scanning their system, Monero found it had never been exploited using this flaw, and by February 21st the problem was patched. To be fair to Monero, they have been open and disclosed full details of the error and all measures taken to rectify it.

    – The privacy element means there are view or no wallets available for full viewing, and so it’s impossible to know about past transactions and what’s really going on in the network. It may be a pro for existing users, but for newcomers it can be a little unsettling.

    It’s clear that one of the biggest pulls of Monero is the ability to remain anonymous without the same suspicion being leveled at you on other platforms where “stealth” is optional (and only used for dodgy transactions, people think). But, after the open-ledger and dominance of more “typical” cryptocurrencies, Monero represents a radical, even revolutionary approach that has a potent allure.

    RandomX CPU mining

    RandomX is a new cryptocurrency mining algorithm designed improve the distribution of mined cryptocurrencies more evenly to a broader base of users. The idea is that everyone with a computer has a CPU, and hence an algorithm that favors the CPU will be more inclusive. Random is is designed to only function on CPUs, with strong resistance to both GPU and ASIC mining. This is achieved by making use of functions only available on modern day CPUs, such as virtualization. RandomX has already been audited and is currently deployed on Epic Cash and will be deployed on Monero.

    Monero – How does it work?

    So how does it work? Each piece of aforementioned tech is used to protect a different element of the transaction.

    The sender is protected by the “Ring Signature,” which attaches multiple names to each transaction, forming a ring around the true sender and obscuring their true identity.

    The receiver is protected by the “Stealth Address,” which sends transactions to a single-use address that will flag up as non-existent should anyone try to look into who the transaction was going to.

    The amount of each transaction is concealed by the “Ring CT,” which only shows each exchange as being more than zero and valid — that’s it!

    Summary of how Monero works

    The conscious crypto user who wants to be anonymous for innocent reasons, but doesn’t want to arouse suspicion, will find the perfect partner in Monero. Privacy is a right, and Monero is one of the platforms offering it openly and genuinely. Not everyone agrees. Some people see universal anonymity as limiting, as it makes it impossible for new users to look into past transactions and determine if everything is kosher. There are even additional tools like their “Kovri” tool which masks IP addresses. To the experienced observer of the Bitcoin ledger, this secrecy can be rather off-putting.

  • Komodo in a Nutshell

    Komodo in a Nutshell

    Komodo ICO (KMD)

    The Komodo ICO ran from Oct-Nov 2016. At the time they raised a total of 2636.37BTC. Komodo is a Zcash fork and so it will have all the same privacy features. However, they are not part of Zcash (ZEC). Their work is built on top of the open-source Zcash project.

    What is Komodo

    The zerocash protocol allows a higher standard of privacy and anonymity to transactions. It makes it  possible to send money online without disclosing receiver and sender information, while at the same time allowing for verification of the transaction’s authenticity. This utilizes a technology called zk-SNARKS.

    Komodo is also developing something called delayed proof of work or dPoW. Komodo has two levels of mining and two separate proofs of work (PoW). Only Komodo has to attach itself to the Bitcoin blockchain. Because of this, third party blockchains can use Komodo as an additional security layer. The Komodo blockchain will have the 64 notary nodes. The notary nodes, apart from finding blocks and recording transactions on the Komodo blockchain, take the confirmed blocks on the Komodo blockchain and notarize or engrave them on to the bitcoin blockchain.

    Other Applications

    Apart from the features listed above, Komodo is also being developed as part of a broader project called SuperNET. SuperNet aims include:

    1. assetchains that allow anyone to create their own asset with its own blockchain
    2. multiwallet where those assets can be stored, including many coins like Bitcoin and Komodo
    3. atomic swaps, so that people can trade their coins from the multiwallet without counterparty risks
    4. pegged assets – which are a form of price-stable assets created on the assetchains – these assets solve the problem of price volatility by attaching themselves to the value of stable currencies like EUR or USD.
