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.
Polymath simplifies the legal process of creating and selling security tokens. It makes a new token standard, the ST20, and enforces government compliance. Only a “list of authorized investors and their Ethereum wallet addresses” can hold ST20 tokens. Therefore, token issuers don’t need to worry about the legal implications of your security falling into the wrong hands. In order to launch a legally compliant token, the Polymath platform brings together issuers, legal delegates, smart contract developers, KYC verification, and a decentralized exchange. All transactions on the Polymath platform take place using the native POLY token. Polymath has programmable equity. Polymath enables companies to take control of their equity issuance through programmable code. It is raising in cryptocurrency opens up an entire wealth of new investors. Polymath eliminates the middleman and financial structures that hinder the deployment of equity. There is a trove of wealth that is untouched by Wall Street that can now be accessed through Polymath. In 2017, Polymath raised over $1.2 billion in funding by selling utility tokens and security tokens. Utility tokens, such as Waltonchain, give you access to a token’s network and are far more common than security tokens. Security tokens, however, provide equity or a claim to dividends from a company. As a result, security tokens, like any securities, are subject to government regulation. Polymath’s new standard for blockchain security tokens aims to embed the necessary regulatory requirements into smart contracts and comply entirely with government security regulations. A wide array of security tokens that will be listed on Polymath at some point will require investors to be accredited, or to be from specific countries.
