Dentacoin is an Ethereum-based blockchain platform regulated by smart contracts. The platform supports the dental community by building and creating solutions devoted to improving the quality of dental care worldwide. The blockchain gives Dentacoin the power to change the world for the better. Dentacoin develops the dental industry as well as creates market intelligence through a cryptocurrency reward system that inspires participation throughout the community. Dentacoin is the first cryptocurrency that uses a decentralized review platform and transparently rewards patients and dentists who make contributions that benefit the community. The Dentacoin Foundation team strongly believes in building a future healthcare industry that will fall into the hands of the people, resulting in the disruption of the existing industries and the creation of new industries in the short and long term. Dentacoin strives to create a dental industry community by rewarding people -who provide valuable contributions- with crypto currency. Through this reward system, the foundation will see a rise in a currency that will be able to reach a broad market, including a vast number of people who have yet to participate in any cryptocurrency economy. According to Harvard Business Review: “To protect the blockchain vision from political pressure and regulatory interference, blockchain networks rely on a decentralized infrastructure that can't be controlled by any one person or group.' The integration of blockchain and dentistry is an extraordinary concept; one that requires the creation of a community in which transparency and shared responsibility can take place. Looking forward, Dentacoin expects the platform to drastically improve dental health and hygiene habits, thus improving the quality of life for individuals resulting in improved overall health and increased longevity.
Nano, a low-latency cryptocurrency built on an innovative block-lattice data structure offering unlimited scalability and no transaction fees. Nano by design is a simple protocol with the sole purpose of being a high-performance cryptocurrency. The Nano protocol can run on low-power hardware, allowing it to be a practical, decentralized cryptocurrency for everyday use. The original Nano (RailBlocks) paper and first beta implementation were published in December, 2014, making it one of the first Directed Acyclic Graph (DAG) based cryptocurrencies [6]. Soon after, other DAG cryptocurrencies began to develop, most notably DagCoin/Byteball and IOTA. These DAG-based cryptocurrencies broke the blockchain mold, improving system performance and security. Byteball achieves consensus by relying on a “main-chain” comprised of honest, reputable and user-trusted “witnesses”, while IOTA achieves consensus via the cumulative PoW of stacked transactions. Nano achieves consensus via a balance-weighted vote on conflicting transactions. This consensus system provides quicker, more deterministic transactions while still maintaining a strong, decentralized system. Nano continues this development and has positioned itself as one of the highest performing cryptocurrencies. Nano is a trustless, feeless, low-latency cryptocurrency that utilizes a novel blocklattice structure and delegated Proof of Stake voting. The network requires minimal resources, no high-power mining hardware, and can process high transaction throughput. All of this is achieved by having individual blockchains for each account, eliminating access issues and inefficiencies of a global data-structure. We identified possible attack vectors on the system and presented arguments on how Nano is resistant to these forms of attacks. Check out CoinBureau for the complete review of Nano.
