MOAC stands for the Mother of All Chains. It is a blockchain platform that supports transactions and data access. It is scalable. Sub-chains and smart contracts are compatible with MOAC. Decentralized apps and cross-chain connections are possible as well. MOAC is based on the Ethereum platform, and it uses a ERC20 currency. MOAC offers more including, A layered configuration structure, Asynchronous contract calls, Sharding solutions and Pluggable validation schemes. Transactions are processed through several consensus systems. The rate is 100 times faster than current blockchain platforms. Sub-chains increase concurrency rates up to 10,000 times. Sub-chains reduce cost and create a test environment. Cross-chain connections allow users and dApps to migrate to the MOAC platform without any knowledge. There’s also a decentralized file storage system. MOAC uses a Proof-of-Work system that allows miners to mine the main chain and sub-chains. Mining can be done from mobile devices. PoW algorithms deter third-party interference, including denial of service attacks and spamming. Sharding is another notable feature in MOAC. This is a method for allocating processing power. The amount of processing power given is proportional to the number of nodes in the network. Large blockchain shards are divided into groups of small shards that are fast. MOAC has lofty ambitions: it uses multichain architecture with microchains built on top of the MOAC base layer. It also plans to enable crosschain atomic swaps between blockchains like Bitcoin or Ethereum, just like Komodo does. Both intend to do so via sharding. The MOAC testnet launched November 2017, and the MOAC ERC-20 token and wallet were created in February 2018. Mainnet MOAC launched at the end of April 2018 with Ethereum support, and a mainnet explorer is available on the MOAC.io website. Sharding is due for a December 2018 release. Tokenized MOAC transactions occur on the base layer, and sidechains handle smart contracts. Sidechain creators determine their individual consensus model, so traditional models like Proof-of-Stake or Proof-of-Skill can be used, along with new hybrid models. MOAC aims to be the mother of all cryptocurrencies, and its ambitions are backed by one of the strongest technical teams in blockchain. Based in China, the team has experience in blockchain, enterprise IT, and more. MOAC is a Proof-of-Work algorithm whose token started as an ERC-20 token on the Ethereum network. This base layer supports tokenization using other consensus mechanisms. MOAC decentralizes block processing using microchains and a technique called sharding. Microchains are cross-compatible and can soon be made cross-compatible with other chains for atomic swaps. MOAC has a strong community mostly based in China, where it has a strong presence across social media. This community can build it into a strong dApp, tokenization, and exchange platform.
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.
