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.
EtherZero, abbreviated ETZ, is a hard fork on ethereum providing no-fee, high expansibility, real-time transaction or operation feedback services. Aiming to be a general-purpose smart contract platform, ETZ helps developers set up DAPPs that not limited in finance and business scope, but those more frequently used in daily life, to popularize decentralized services to more people and industries. ETZ eliminates the gas fee system from Ethereum network core and adds a Transaction Restriction Policy Protocol layer that associates the threshold, frequency, depth, etc. of initiating transactions with the account balance to combat DDOS like attacks. In particular, ETZ also draws on DASH's two-tier network architecture built with Masternodes transaction verification network and blockchain ledger layer, and its built-in community autonomous system to provide users with real-time operation feedback and high transaction concurrency, no longer need to wait for a long transaction confirmation time. ETZ picks the proven experience of Ethereum on smart contracts, removes its less scalability gas-based fee system and designs a fully accountable trading limit and security strategy against DDOS Class attacks. The final two-tier network composed of the main node and pow consensus layer laid the foundation to achieve free of charge, high concurrency, real-time transactions, independent evolution and several other features. What does no-fee mean to DApp Dev? Taking a simple Todolist DApp as an example, its decentralized implementation can be applied to the team task decomposition process, which requires all participants in the project to know the tasks of other members. Each task is a team consensus result with demand of traceability. The application involves registration of members, additions, deletions and alterations of tasks. According to Ethereum development requirements, all of these operations require gas consumption, which is clearly unreasonable for the users of the application. While in EtherZero, the transaction initiation frequency and the execution depth of smart contracts will be positively related to the balance possessed by the account. This mechanism is similar to POS, it takes into account the fair use of bandwidth and set a relatively high capital threshold required to launch a DDOS attack by malicious attackers while providing free services. This kind of limited and cost-effective free mechanism will spread the decentralized application into the scene of life.
