QuarkChain's Strengths and Weaknesses: Open Discussion Thread
Since there already exist literally tons of general reviews on QuarkChain's technology, token metrics, ICO, etc., this post is intended to discuss more details of QuarkChain's technology, it's strengths and improvements compared to other technology but also to constructively identify potential threats and issues for a better overall understanding. This is not an ICO review or the like, rather an open discussion thread to which I am inviting all kinds of CONSTRUCTIVE and CRITICAL input or questions from experts and newcomers to share our knowledge and learn from each other. As I am not a programmer or blockchain expert, learning is my main motivation in starting such a discussion, which I see as an important complement particularly for projects like QuarkChain that I personally follow closely with high interest. As most of those familiar with the current ICO scene are probably already aware of, QuarkChain is a new PoW blockchain project that addresses one of the most highly debated issues of today's blockchain technology: scalability. In simplified terms, QuarkChain attempts to achieve up to 1 million tps (transactions/second) through sharding technology with a 2-layer blockchain architecture (rootchain and minor chains) in which the minor chains (=shards) carry the transaction data and the root chain handles the confirmation and consensus through processing the block hashes of the shards. I find this restructuring of the architecture to process only block hashes in the root chain a simple and great solution (yet surely not so simple to implement in all its details) to reduce the root chain’s data processing and enhance the blockhain's overall throughput. From the available materials on QuarkChain's technology, I see the following features as major strengths: 1) In-built sharded architecture: This definitely appears to be a promising attempt to enhance scalability, even more since QuarkChain also implements a cross-shard transaction solution. 2) Clustering nodes (see whitepaper 5.1): Instead of running only full nodes that require to process the entire data history, QuarkChain proposes a structure in which nodes can cluster together and form a full node that covers root chain and minor chains, while each single node in the cluster only processes a sub-set of chains. Without being an expert, it seems very logical that as soon as a blockchain processes thousands and hundreds of thousands of tps the CPU and data storage requirements grow to an extent that the maintenance (=mining) of the blockchain becomes restricted to only specialized nodes with such capacities. This would result in centralization that is moreover expensive and might even affect transaction costs. Some form of clustering of nodes seems to me a key feature for scalable blockchain technologies. However, I am not qualified enough to assess potential security risks and would be glad about any response or feedback in this regard. 3) EVM support: While I see smart contract support in general as an important feature of blockchain technology, the support of Ethereum Virtual Machine is especially smart from a marketing perspective, since it allows projects run on Ethereum easily to swap to QuarkChain. 4) Different difficulty and reward levels of the hash puzzle: In combination with the clustering of nodes, this feature fosters decentralization and counteracts centralization through mining pools as we can see it with Bitcoin. While it does not prohibit centralization by design, it incentivizes decentralization through offering different mining difficulties and rewards for different chains, so everyone can decide more independently on the most profitable ways to participate in mining (alone, clustering, pooling). Among the many questions I would have, I raise the following 3 critical ones (as a newcomer...): A) Security: Due to QuarkChain’s 2-layer structure, e.g. a double-spending attack only requires >25% of the overall blockchain’s hash power, namely >50% of the root chains hash power that is currently set at 50% of the overall hash power (cf. e.g. whitepaper 4.2). While I understand the argument that QuarkChain’s incentives to increase decentralization (see above point 4) counteract pooling of hash power, they cannot fully prohibit it and I would argue the behavior of QuarkChain’s users and miners will be difficult to predict. It remains open whether there remain enough incentives for miners to pool together. Moreover, I would have the question whether the required >25% for manipulation can be achieved through the clustering of nodes to build a “super full node” in QuarkChain’s architecture? If my understanding of QuarkChain’s technology is correct, the distribution of hash power between root chain and minor chains is flexible, so that security can be enhanced by increasing the root chain’s hash power to 60%, 70%, 75%, etc. of the overall hash power. This feature to flexibly adjust the security level to requirements seems to be a very strong feature of QuarkChain, however am I right to assume that the tradeoff would be decreased scalability due to less hash power on the shards that process transaction data? B) Security: A very technical question is connected network level attacks. Different research has been produced that focuses on potential threats for blockchains through e.g. network partitioning. Attackers first target the communication between users/nodes/etc. to block interaction and then start e.g. a double spending attack (cf. e.g. btc-hijack.ethz.ch/files/btc_hijack.pdf and www.usenix.org/node/190891). How does QuarkChain behave/react in such a case, particularly if someone only needs to reach >25% of hash power in QuarkChain’s protocol for manipulation? Can it be counteracted through increasing the hash power of the root chain? C) Ecological impact: QuarkChain's whitepaper describes the desired main features of blockchain technology as threefold: Decentralization, Security and Scalability. These three create technological conflicts between each other that result in trade-offs for which QuarkChain offers a solution. However, I would like to raise the question about a fourth feature I see critical to any new technology nowadays, namely ecological efficiency/eco-friendliness. Is QuarkChain with its PoW consensus able to reduce the required computational power to be eco-friendlier compared to e.g. Bitcoin? QuarkChain's technology offers different difficulty levels of hash puzzles for the different chains in order to counteract pooling of hash power, and decreased difficulty levels might also result in significantly lower hardware requirements for miners. However, does this really affect positively the overall hash power and thus energy cost of maintaining the QuarkChain? (I would assume yes, but I am no expert...) If not, how eco-friendly is QuarkChain compared to e.g. Bitcoin? I would be happy about any response or other contribution on QuarkChain's technology. Please keep in mind to remain critical and constructive and avoid any unnecessary off-topic comments, hyping or personal attacks. As long as concerned with the topic, please feel free to ask any questions and also help answering them. I would like to raise awareness about QuarkChain and learn more about its strengths and weaknesses.
QuarkChain is a secure and decentralized high-scalability peer-to-peer transactional system that has its target set on having more than 100,000 transactions per second (TPS), which seems to be quite ambitious as compared to other cryptocurrencies such as Bitcoin, which has a TPS of 4. As QuarkChain aims to take on the global standard of cashless, electronic transactions, how does it compare to VISA, one of the most widely used payment channels in the world today? QuarkChain aims to achieve a TPS of more than 100,000, which is more than that of VISA. This means that both QuarkChain and VISA are able to handle a huge amount of electronic transactions instantly and on a global scale. However, that’s where the similarities stop. Firstly, as with other cryptocurrencies such as Bitcoin, QuarkChain is decentralized, secure and has all the properties of a cryptocurrency. This means that unlike credit cards, it is impossible for the user to risk fraud as QuarkChain is digital and can’t be reversed or counterfeited by the sender or a third party. There will not be complications such as cancelation of transactions or credit card charge-backs. Secondly, the transaction fees incurred through QuarkChain would be minimal, as compared to VISA, which can incur charges for the user anywhere from 0.5% up to 5%. With a cryptocurrency such as QuarkChain, the user would also not have to worry about other types of fees that could possibly be incurred such as foreign transaction fees and late fees. Thirdly, using QuarkChain allows for more confidential transactions. In the case of QuarkChain (as well as other cryptocurrencies), the exchange of information is done on a “push” basis, whereby the sender can send exactly what he wants to the recipient, as compared to credit cards which employ a “pull” mechanism where the merchant initiates the payment by pulling their designated amount from the credit card account. This therefore provides more security for the crypto user’s privacy, such as his financial history and other information. As a result, the risk for identity theft is also eliminated. Finally, in traditional credit card or banking systems, the user submits his assets to a third party who can exercise control over what the user has with them. However, for QuarkChain, you have sole ownership of your corresponding public and private encryption keys that make up your cryptocurrency network identity or address. The user can therefore be rest assured that no one else can access or mess with his digital currency without the encryption keys. In conclusion, QuarkChain is an entirely different approach towards cashless transactions as compared to VISA, or even other cryptocurrencies such as Bitcoin. It has the potential to become a conventional means to cashless transactions on a global scale and when that happens, it will benefit both merchants and consumers as a result.
After the yet another crash in price of Bitcoin, Quark also fell by a further 20%. The price of Quark and essentially all altcoins is so inherently bound to Bitcoin at present that to view them from a monetary point of view as separate is a pointless endeavour. But that's a good thing. Keep supporting the community, developing infrastructure and promoting Quark and the ideology of cryptos to your friends and colleagues. Bitcoin will rise to levels far beyond what it is currently valued at and so too will all the deserving altcoins, Quark included.
Bolivia added its official opinion on Bitcoin to the melting pot this weekend with the Central Bank announcing an outright ban of any currencies other than the boliviano. Information circulated by PanAm Post includes bank references to Bitcoin, Quark, Peercoin, Namecoin, Primecoin and Feathercoin, but sentiment seemed to intimate complete protection of the boliviano’s sovereignty. “It is illegal to use any kind of currency that is not issued and controlled by a government or an authorized entity,” authorities proclaimed. While this is a dampener for the Bitcoin scene in South America, Bolivia is something of a blot on the landscape of what has become a broadly crypto-friendly continent. While governments are far from entirely embracing, popular support means that cryptocurrencies have already gained sufficient momentum to make one country’s official rejection seem very unlikely to hinder progress. Indeed, Argentina’s similar hostility towards Bitcoin has only precipitated its acceptance among the general populace, and development of the space is as spontaneous and well-received as ever. Bitcoin has successfully shrugged off Bolivia’s snipe, but you can count on CoinTelegraph to bring you the latest developments from all over the world – follow us to make sure you don’t miss out!
Shame on you Bill Still! You hate on bitcoin for 2 years and now think, oh now I get it, shit I missed out! Then you scam your own loyal fan base with the pre mined scam coin quark! I have lost all respect.
Hi fellas, this is my first ever post on privacy. I recently wrote about the existence of an open source DLT-based decentralized marketplace with a mission to enable free and private trade of goods and services. The marketplace description was posted on another subreddit but I think it's worth posting the description here too. Tbh I cant think of anything that qualifies more as "The intersection of technology, privacy, and freedom in a digital world" I hope my own description of the marketplace and its technology bellow will fuel your interest to read more about it. My even bigger hope is that some of you will decide to become first-hand beta testers as soon as the upcoming v3.0 of the marketplace hits the testnet (eta: a few weeks). You can also use the existing version (currently 2.3.5) of the marketplace to buy or sell products on the publicly accessible single community market there (or just play with it). The marketplace: It is called the Particl Marketplace and its ground breaking V3.0 is set to be released after 3 years of hard development work. The V3.0 will be the first version aimed at a wider public (normies and not only tech geeks). It will allow anyone to create easily decentralized personal storefronts or community markets or simply buy/sell goods on existing markets. The user-created markets/storefronts on the marketplace can be public if the access key is publicly announced on the Particl network or absolutely invisible to anyone that doesn’t know the access key (held by the creator). This is an intentional privacy feature and simply put, if you dont have the market access key (essentially a decryption key) there is absolutely no way to see/detect that some market exists. The marketplace is private by design and decentralized, with no middlemen or intermediaries whatsoever. The trades are protected by a two-way automated escrow via smart-contracts that de-incentivize and penalize dishonest behavior on both sides. In particular, the buy-flow forces the buyer to deposit 1x item value + payment and the seller 1x item value (+ sends item) into a common smart contract. If the buyer receives the product/service and its all good, then he unlocks the escrow so both can get their 1x item value deposits back and the seller receive his payment. The marketplace takes no sales commissions from the storefronts/markets and charges only a tiny listing fee (<0.01$) to prevent product listings spamming. All the marketplace generated fees go to the staking nodes that provide the hardware infrastructure for the p2p network to operate. The network nodes can be public or you can run them as Tor hidden services. The technology: The Particl Marketplace is crypto-agnostic and currently supports payments in BTC, PART, ZCoin (XMR, DAI, NIX, USDC, USDT are next in the pipeline and many more to come). It uses as a settlement layer its native coin PART and own blockchain, which is an up-to-date Bitcoin codebase with added privacy features like CT, RingCT (up to 32 mixins), Stealth addresses, etc. These privacy features are used in combination to keep the financial data, like escrows and transactions, private and most importantly un-linkable to the actual market buys/sells. For the users and markets related data exchange like posted listings, buy/sell flows, encrypted user communication, built-in cryptocurrency exchange, etc, the marketplace uses a DSN, currently its a custom Bitmessage variant called SMSG, which allows metadata stripped encrypted p2p data exchange (no sender, no receiver) Last but not least the marketplace desktop app (Particl Desktop) has a built-in option for using the Tor network via proxy. The important people: The cypherpunks behind Particl Marketplace have been OGs freedom advocates and pioneers in the privacy DLT field. For example, they were the first ever to implement features like RingCT, Bulletproofs, PoS, cold staking, etc on a Bitcoin codebase. Their privacy features implementations have been audited successfully by several respectable academics and security R&D providers, like QuarksLab. The team behind the project has been so far focused on building without any marketing/awareness efforts and thus have remained intentionally in the shadows. The latter is planned to change with the v3.0 release. One of the steps towards that will be the initiation of several long-planned awareness campaigns, like the Vendor Onboarding and Outreach Program, the Particl Academy (an easy to understand and learn about the technology portal) and many more. Me: I am a passionate freedom and privacy advocate that discovered the project 1.5 year ago and since then has become a member of their small but like-minded community ([email protected]/discord). My personal belief is that the Particl Marketplace provides a game-changing/breaking usecase to the world. At the minimum, due to the open source nature of the project, it will be a proof of concept that is bound to shift the global eCommerce paradigm.
Is PIVX as anonymous as Bitcoin and Monero and is Quark as Secure as CryptoNote and SHA-256
I'm new to PIVX, I was wondering if PIVX is as anonymous as bitcoin and monero. Also I'm intrigued to know if Quark is as secure as SHA-2 (SHA-256) which is what Bitcoin is developed on and CryptoNote which Monero is developed on.

Hi fellas, this is my first post on the darknet. I read today about the Empire Market and decided to post here about a tech that might help to end this charade of constant exit scams.

ICO Review in Deutsch von @Quark_Chain. Der Hype ist enorm!! Was denken wir darüber. #Crypto #Cryptocurrency #Bitcoin #Blockchain #Investing #ICO #ICOs #ICOReview #Airdrop #Review #blockchaintechnology #Blockchaincommunity https://t.co/TfAktymjxX
I've just used the first Bitcoin ATM in London, and realised that Quark is so much better for real world situations!
I've just returned from London. I have been talking to lawyers, accountants and some potential investors about Quark and crypto-currencies in general. It made me realise that while for us these concepts (blockchain, mining, hashrate etc) are common sense, to ordinary people these concepts are still as mysterious as one from another planet. But ALL people that I talked to and helped install the Desktop wallet and Mobile Wallet and gave quarks, -- they are all very positive and excited about Quarks -- especially when I would send quarks from a Desktop to their Android smartphone and it would arrive instantly in just 1 second and confirm (become spendable) in 30 seconds. I also went to see the first Bitcoin ATM in London, which is located at a small dingy cafe in Shoreditch (Old Street). The cafe is called "Shoreditch Old Station". It's a Lamassu ATM (which can easily be reprogrammed for Quark and they cost $3000-$5000). I bought £5 worth of Bitcoin just to demonstrate to a friend the whole concept of crypto-currencies how it works. Then we sat in that cafe for 10-15 minutes waiting for at least 1 confirmation, so that we could buy coffee. It is in real life situations like these that you realise that Bitcoin is actually not very user-friendly, and just how much better Quark is! We were nearly ready to leave and then finally the 0.012 BTC finally showed up in my iPhone Blockchain app and I purchased the coffee. The whole experience made me realise that Yes, the businesses want to adopt crypto-currencies, but in the long run it will not be Bitcoin -- people and businesses will prefer a currency like Quark which arrives instantly and becomes spendable 30 seconds later. The whole experience with Bitcoin in the real world made me feel very optimistic about the future of Quark. I think since we are all early adopters, each one of us should do something to spread Quark adoption. Speak to small businesses, demonstrate how Quark works, explain why it is better then Bitcoin and make them accept Quarks. That's the best thing that can help raise the REAL value of Quark at this stage. For example, I have spoken to a taxi driver and he is very excited and wants to start accepting Quark (although he uses iPhone and doesn't have Android phone) -- I'm meeting him later today to help him install the Desktop Wallet and to demonstrate how Quarks are sent and received. Now that Quark has an Android Wallet app on Google Play, it is getting ready for adoption outside the tiny reddit cryto-community. Personally, my next step will be to talk to the Students' Union of my local University to see if their bars and food outlets can start adopting Quark and if they can install a Quark ATM.
