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.
PacCoin (PAC), or the People’s Alternative Choice Coin, is a lesser-known coin that’s been sitting since 2015. It experienced rapid inflation during 2017, which might be attributed to generous mining rewards. At the start of 2018, PAC had become one of the cheapest cryptocurrency coins out there, with a relatively large total supply of roughly 3.5 trillion coins and a planned cap of 100 trillion. It has a devoted community that hopes to see their holdings come to fruition and make them rich, believing in its future as an “Internet penny” that lends itself to micro-transactions. PACcoins started to trade at 0.0000$ as of only a couple of days ago. Later on, the coin gained some on its price with a couple of increases that helped the price jump from non-existent to existent. After the latest decrease that made the price drop for over –9%. This decrease led to the current price of 0.000031$, which is still better than having the coin traded at 0$. For now, it remains uncertain what will happen with PACcoin and how well this coin will perform after being re-launched three weeks from now. For now, we strongly advise to give this token a thought and consider investing – the price is still too low, so even if the coin drops again, you won’t be losing much money.
