Groestlcoin is an ASIC-resistant cryptocurrency that boasts having “almost ZERO fees.” Although the coin itself is only pseudo-anonymous (like Bitcoin), the development team has ported a wallet (Samourai) to give you full anonymity. Groestlcoin is strictly a cryptocurrency for peer-to-peer (p2p) payments. The coin serves the same end-goal as other transactional cryptos like Bitcoin and Litecoin but accomplishes that goal with a different set of attributes. Groestlcoin accomplished a few significant “firsts” with its feature set. It was the first coin to implement Segregated Witness (SegWit) and the first to perform a Lightning Network transaction on mainnet. With the implementation of the Lightning Network, Groestlcoin has minimal fees. Transferring 10,000 GRS (~$6000 at the time of this writing) costs fractions of a fraction of a cent. Even if the GRS price rises 1000x, the transaction fee would be just a couple of pennies. Groestlcoin utilizes two rounds of Grøstl-512 for its mining algorithm. This mining algo is ASIC-resistant, for now. A developer going by the Bitcointalk username “Gruve_P” launched Groestlcoin on March 22, 2014. Since then, the team has grown to over 20 people spread all around the world. Most team members prefer to stay relatively anonymous, only sharing their first name and country of origin on the website. The team has been consistent in releasing new versions of the platform every three months. With such consistency, it shouldn’t shock you to hear all that they’ve accomplished in the last four years. The team activated SegWit in January 2017 and is currently working on Lightning Network releases for both their mobile and desktop wallets. The team and community have also built eleven different Android wallets, ten different wallets for Blackberry, and three for iOS. They’ve created more than ten desktop wallets as well. GRS has recently seen a rise in popularity, with most CPU and GPU miners moving away from networks like BTC, where ASIC miners have completely saturated the mining pool. With its robust features, focus on privacy, and innovative technology, GRS is a very lucrative choice for these miners, and has the possibility to be the next big coin that hits the market. While investing in any cryptocurrency is subject to their inherent volatile nature, the immense market potential of Groestlcoin, along with its pioneering technology and dedicated development team, make it a very strong consideration for investment.
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.
