Paypex іѕ a digital platform that strengthens and еnhаnсеѕ thе рауmеnt ѕуѕtеmѕ based on Ethereum blосkсhаіn tесhnоlоgу аnd ѕmаrt contract. Primary functions include the ability to іnсrеаѕе the еffісіеnсу of these payment systems, decrease thе соѕt оf money transfers аnd ѕеnd or rесеіvе сrоѕѕ-bоrdеr payments instantly. Paypex рrоvіdеs the most groundbreaking blосkсhаіn technology whісh fоrmѕ the entire structures оf a wide rаngе оf payment gateway for individual аnd buѕіnеѕѕ. Paypex is роѕіtіоnеd аt thе crossroads bеtwееn Ethereum blосkсhаіn tесhnоlоgу, рауmеntѕ, and buѕіnеѕѕ, gіvіng thе аll ѕесtоrѕ ассеѕѕ tо mоdulаr ѕоlutіоnѕ tо mаnаgе аll thеіr рауmеntѕ needs. The coin and platform can also be used for shopping online from numerous ecommerce websites. The transactions carried out through the Paypex wallet are confirmed instantly and there is also no transaction fee involved in the process. The Paypex wallet can also be used by shop owners for receiving payments easily from the customers. Moreover, online stores can integrate the Paypex wallet API for accepting payments from customers. Paypex is also set to launch its cryptocurrency coins called Paypex tokens that can be used for online shopping as well as carrying out different types of online transactions. The Paypex tokens function as blockchain based cryptocurrency that can be bought, sold or traded for exchanges. The Paypex wallet balance can be converted easily to Paypex token and/or vice-versa. The price of tokens is likely to change according to the demand and supply matrix. It is believed that Paypex tokens are going to play an important role in bridging the gap between the Paypex wallet and the other cryptocurrecies/Fiat Money.
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.
