FunFair is an Ethereum-based platform for online casino gaming. Targeting the $47B online gambling market, FunFair isn’t actually a casino. Instead, the underlying gaming technology is licensed out to casinos and other gambling platforms. The FunFair team is attempting to solve some of the biggest problems online casinos face: slow performance, high operating costs, and lack of user trust. Through the use of blockchain technology and Fate Channels, an in-house built version of state channels, the products they license have the potential fix all of them. FUN is an ERC-20 token that you use in every part of the FunFair platform. It’s the only token accepted for in-game credits, how game creators in the marketplace are paid, what casinos must pay their licensing with and receive revenues in, and all fees on the platform must be paid in FUN. A total of 11,000,000,000 FUN tokens were created on June 22, 2017, and no more will be created. With a fixed supply, the token is deflationary and should experience sharp increases in price over time as demand for it increases. Furthermore, the FUN that’s paid as fees will be burned for the first two years which should further drive price upwards. Casinos can also stake the FUN tokens in their bankrolls to receive additional dividends. The 30+ person FunFair team is based out of London and is led by Jez San, OBE. San’s entire career has revolved around entrepreneurship and the computer gaming industry. He founded Argonaut Software as a teen and created the first chip to power 3D games like Star Fox and Harry Potter. Rounding out his resume, San also founded the 3D online poker room, PKR, and is an investor in one of the world’s leading cryptocurrency exchanges, Kraken. Other members of the team are just as impressive. Jeremy Longley, founder and CTO, co-founded PKR with San and has over 15 years of experience managing development teams. FunFair COO, David Greyling, was previously the International Director of William Hill – a worldwide betting and gaming company. FunFair is attempting to enter the gigantic online gaming market by providing a solution that’s unique to the blockchain industry. Instead of acting as a casino, the company is licensing out their technology to other casinos which helps to mitigate their liability and risk. The project already has a working product and plans to launch early this year. With the wealth of experience that the team has in the gaming space, it’s hard to see this project failing. If FunFair can overcome the market domination of current incumbents using traditional technology, blockchain-based casino games could be the new industry paradigm.
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.
