NEM is a highly versatile crypto solution which seeks to adhere to a host of mainstream industry requirements. It is written in Java and JavaScript with 100% original source code. NEM has a stated goal of a wide distribution model and has introduced new features in blockchain technology in its proof-of-importance (POI) algorithm. NEM also features an integrated P2P secure and encrypted messaging system, multisignature accounts and an Eigentrust++ reputation system. Essentially, NEM is designed as a financial blockchain solution and can be used for payment, clearing and settlement in a private environment which is highly controlled. This means that NEM meets several of the regulatory requirements and guidelines in the financial industry. This allows it to be used to settle (change of ownership) any asset via the blockchain. Mijin which is a private chain of NEM has gained popularity and companies such as Hitachi have already embraced it. Why NEM? Many banks around the world have come to accept the importance of blockchain technology. In fact, a good number of banks in the U.S, India and Japan have already started using the technology. Because banks generally employ the smart contract concept, NEM’s platform which is asset-friendly can be used to settle any asset. In settling assets, speed, security, and reliability are very important to a mainstream institution which is what this crypto offers. NEM addresses these issues by repackaging its blockchain into a private chain and presenting it as Mijin. NEM crypto is also applicable in the technology world. Unlike Bitcoin and Dogecoin which use mining to increase the number of coins, XEM uses something called ‘harvesting’. In this process, blocks are generated and a person is rewarded for work contributed using transaction fees. Every block has a certain number of transactions which attract an unknown amount of fees. This keeps the participants incentivized to continue harvesting. For a blockchain user to be allowed to harvest, one must go through a forging mechanism process called Proof-of-Importance (POI). POI is the algorithm used in NEM to time stamp transactions. A NEM user's importance is determined by how many coins they have and the number of transactions made to and from their wallet. POI uses the NCDawareRank network centrality measure, the topology of the transaction graph, as well as a number of other relevant signals to achieve consensus. POI is different from other initiatives which use a fee-sharing model that does not take into consideration one's overall support of the network. In proof-of-stake systems a person needs to have large numbers of coins to form a block, but in NEM transactions volume and trust become factors. This was designed to encourage users of NEM to not simply hold XEM but instead actively carry out transactions. To be eligible for entering the importance calculation, an account must have at least 10,000 vested XEM. All accounts owning more than 10,000 vested XEM have a non-zero importance score. With a supply of 8,999,999,999 XEM, the theoretical maximum number of accounts with non-zero importance is 899,999. In practice, the number of actual accounts with non-zero importance is not expected to approach the theoretical max due to inequalities in held XEM and also the temporal costs associated with vesting. If NEM becomes very popular, a threshold of 10,000 vested XEM could be undesirable. If necessary, this number could be updated in the future via a hard fork, which is the same procedure for adjusting transaction fees and other parameters related to harvesting.
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.
