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.
Curecoin is a new SHA-256 based cryptocurrency with a big vision, that is - Curing Cancer, Alzheimer's, Huntington's, preventing viruses, and designing next-level of pharmaceuticals. Curecoin can be earned with both GPU and CPU. Folders use high-end GPUs and CPUs to fold proteins, earning a proportional amount of coins set-aside for their contributions. SHA-256 ASIC Miners could still get along by mining Curecoin as usual which will further secure the blockchain and the network. Whether you are heavily-invested in ASIC equipment or still have GPUs and CPUs, you can participate. Due to the nature of folding (diverse, constantly changing, not easily predictable), GPUs and CPUs will both always be relevant, so an investment in consumer hardware isn't wasted. Curecoins go to three main areas: Folders, Miners, and Developers. The folders get 76% of the total coins (80% of the coins distributed per day). SHA256 miners get 19% of the total coins (20% of the coins distributed per day). 2% of the total funds are distributed to people who donated to project development. The other 3% is dedicated to Curecoin developers, and will be used for paying for development costs (such as hiring professional programmers, paying for infrastructure, etc.), and for giving back to the community (folding hardware giveaways, faucets, covering 0% mining pools, etc.).
