Monero Classic XMC

Monero-Classic (XMC) is a hard fork of Monero (XMR), announced on 29th March. Part of Monero's development is that it hard-forks every 6 months, this is completely normal so not a surprise. After one of these scheduled hard-forks Monero retains the ticker symbol 'XMR' as well as the upgrades from the hard-fork; on the 6th April hard-fork it had changes including resistance to Cryptonight ASIC miners. If people disagree with these hard-forks, they can create their own versions of Monero. The strong financial incentives against this hard-fork, resulted in 4 different entities that each has created versions of Monero that still support ASIC miners, with their own new ticker symbols: Monero (XMR), the coin supported by the core Monero development team Monero Original (XMO), announced on 29th March Monero 0 (ZMR), shared on Reddit on 31st March 2018 MoneroClassic (XMC), first Tweet on 4th April 2018 Monero-Classic (XMC), first Tweet on 5th April 2018 On the project website, the person behind Monero-Classic identifies himself as “PZ, an early Bitcoin evangelist and blockchain eco builder”. PZ's message on the website: Hello, everyone! I'm PZ, an early Bitcoin evangelist and blockchain eco builder. Most of you know me because of my efforts and adherence to the ecological development of blockchain industry. In the past few years, I saw Bitcoin community and Litecoin community both fell apart for long time due to different ideas , and the development of main chains was unable to move forward. So I organized Litecoin International Round Table Forum and Bitcoin International Round Table Forum in 2017. The two meetings were very successful. The upgrade of Litecoin and Bitcoin also went on successfully. Recently, our team noticed that XMR (Monero), the world’s largest anonymous currency, is about to change the PoW algorithm, and plans to further change it twice within 1 year. As we all know, the reason for this algorithm change is that many companies (BITMAIN, PinIdea, etc.) have developed specialized mining machines for Monero. Actually, the emergence of specialized mining machine for a cryptocurrency is normal market economy phenomenon. In the 10 years since the cryptocurrency community was born, we have seen the birth of specialized mining machine for Bitcoin. Then there emerged Litecoin, which was expected to be against specialized ASIC mining machines, using script algorithm which was considered to be'against ASIC' at that time. While after only two years, there appeared specialized mining machine for Litecoin. We considered about whether to change algorithm to be against specialized ASIC mining machines or not. However, after prudent and serious discussion, we believe that for any kind of valuable algorithm, the emergence of mining machine is only a matter of time. Finally, we made our choice to accept the existence of professional mining machines. Now more and more high-value currencies (algorithms) have respondent specialized ASIC mining machines, which has become a common phenomenon in the industry. Is the existence of specialized mining machines completely useless? Obviously, this argument is unfair. The emergence of specialized mining machines will indeed accelerate the rise of problems such as centralization of computational power. But we should be reminded the fact that emergence of professional mining machines will also greatly improve network security. If there are professional mining machines, the events like “Monero was attacked by more than 500,000 botnets” could be avoided. We understand that Monero team expects to stick to the expectations and work of Monero's “against ASIC mining machine”. For a long time, due to the excellent work of Monero team, XMR and its community have achieved great development, providing much valuable contributions to the entire cryptocurrency community. In the community, many people agree with this hard fork of changing algorithms. However, I feel that there is still a part of people who want to maintain the original algorithm and accept the existence of mining machines. They should be heard and respected. We believe that the two ideas of 'embrace ASIC mining machines' and 'against ASIC mining machines' both have their own strengths and weakness. At present, the vigorous development of the global cryptocurrency ecology is precisely due to the emergence of various ideas of different people. The collision of different ideas has brought out the flourishing of various digital currencies. We always believe that the ecological diversity of cryptocurrency community is much conducive to the birth of a more secure, stable, prosperous and beautiful encrypted world. We can, and should, allow these minority of people, who are adhering to a different idea, be given equal opportunities with the majority, and the free market will make its own choices. Therefore, we believe that these two thoughts should be given equal opportunities for development. We will make our best efforts to maintain the Monero system before this algorithm change, thereby preserving the fire that gives the ecology more potential for development. At the same time, we also invite developers, mining machine manufacturers, trading platforms, miners, purses, and others in this ecological chain to join us, so that the network ecology can gain more possibilities!

QuarkChain QKC

QuarkChain is a secure, permission-less, scalable, and decentralized blockchain. One of the goals of QuarkChain is to utilize sharding technology to deliver over 1 million transactions per second (tps). Essentially, QuarkChain markets itself as a peer-to-peer blockchain with a high capacity throughput to help deliver fast and secure decentralized applications. The team behind QuarkChain created this blockchain to resolve the issue of scalability that all the major blockchains are currently facing. The team feels that because of the urgency of this issue, the Bitcoin community simply cannot afford to wait until they all agree on a solution. Instead, they feel that by offering different solutions, such as the one inherent in QuarkChain, this compels the community to split via a hard fork and find the solution that works best. QuarkChain encourages increased decentralization through multiple cheap nodes that then create a cluster that works as a super-full node. This prevents the high expenses associated with super-full nodes when the tps gets high. In terms of protection, all transactions within QuarkChain get the protection of 50 percent of the network’s hash power. This makes a double-spending attack incredibly challenging, particularly when combined with QuarkChain’s decentralized nature. QuarkChain relies on a two-layer blockchain structure. Sharding blockchains known as shards are the first layer, while the second layer is a root blockchain that confirms the shards’ blocks.The major work on QuarkChain began in Q2 2017 with research into the problem of blockchain scalability. In Q4 of that year, the team drafted the whitepaper. In February 2018, it released the white paper and completed verification code 0.1. March 2018 saw the 0.1 versions of both the wallet and testnet. Now in Q2, the team is working on the testnet 1.0 and smart contract 0.1. In Q4 2018, the team will have the QuarkChain Core 1.0, along with the mainnet 1.0 and the SmartWallet 1.0. By Q2 2019, both the SmartWallet and QuarkChain Core will be in their 2.0 versions. QuarkChain is a decentralized blockchain network that aims to resolve the issues of scalability that plague existing networks by using sharding technology. In this way, QuarkChain can dramatically extend the usefulness of blockchain technology since many applications are limited by the scalability of existing blockchain networks. The project is still in progress, but QuarkChain has already made many positive steps and already began invite-based beta testing for the testnet, showing significant progress and potential. The main features of Quarkchain are: 1. Reshardable two-layered blockchain: Quarkchain consists of two layers of blockchains. We apply elastic sharding blockchains (shards) as the first layer, and a root blockchain as the second layer that confirms the blocks from the first layer. The second layer that confirms the blocks from the first layer. The second layer is flexible to be resharded as needed without changing the root layer. 2. Guaranteed security by market-driven collaborative mining: To ensure the security of all transactions, a game-theoretic framework is designed for incentives, where at least 50% of overall hash powers are allocated to the root chain to prevent double spending attack on any transactions. 3. Anti-centralized horizontal scalability: In any blockchain network with a high TPS, a super-full node can be extremely expensive, which encourages centralization. In contrast, QuarkChain allows multiple cheap nodes forming a cluster to replace a super-full node. 4. Efficient cross-shard transactions: Cross-shard transactions in QuarkChain can be issued at any time, and confirmed in minutes. The speed of cross-shard transactions increases linearly as the number of shards increases. 5. Simple account management: There is only one account needed for the entire blockchain (shards) in QuarkChain. All cryptocurrencies from different shards are stored in one smart wallet.
