Qtum is a decentralized and open-source smart contracts platform and value transfer protocol. Qtum uses proof-of-stake consensus, meaning node operators are rewarded for validating transactions. It is a DGP governed blockchain where community participants can vote to change certain network parameters. Qtum is built on a bitcoin core fork, but the foundation has created its own hybrid blockchain with the help of several key tools. The coin uses bitcoin’s chain because of its simple and stable nature, allowing the foundation to build upon it more easily. As the QTUM project is a hybrid of Bitcoin and Ethereum, its team comprises of members from both Bitcoin and Ethereum community. They also have team members who formerly worked with Tencent, Alibaba, Nasdaq etc. Apart from that, they are backed by some notable VCs and prominent people from the Blockchain community such as Patrick Dai (Project Co-Founder), Neil Mahi (Chief Blockchain Architect/Co-Founder) and Jordan Earls (Lead Developer/Co-Founder). Qtum provides a Turing-complete blockchain stack and is able to execute smart contracts and decentralised applications like the Ethereum blockchain. Qtum builds on Bitcoin's UTXO transaction model and uses the Proof-of-Stake algorithm. It is backed by some highly prominent members of the blockchain community such as Anthony Di Iorio, Xu Star, Bo Shen, David Lee, Jehan Chu and Roger Ver. Qtum sold over 10 million dollars’ worth of its tokens after only 90 minutes, eventually raising a total value of $15.7 million before stopping the campaign early after only 5 days. They raised a total amount of 11,156.766 bitcoins (BTC) and 77,081.031 ether (ETH) in exchange for the 51 million Qtum tokens being distributed to the public. In Qtum’s whitepaper, 51% of the coins were distributed to the public via the crowdfunding campaign. Of the remaining 49%, 29% of the coins would be allocated as community incentives, and the remaining 20% would be distributed to the early backers and development team.
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.
