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.
Ethereum Classic is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third party interference. Ethereum Classic is a continuation of the original Ethereum blockchain - the classic version preserving untampered history; free from external interference and subjective tampering of transactions. Transaction Finality Ethereum Classic believes the core value proposition of any blockchain is immutability; valid transactions can never be erased or forgotten. Individuals interacting on Ethereum Classic are governed by this reality; Code is Law. This does not necessarily mean that code replaces existing laws, or that only code is law (there are many geographical jurisdictions), but it gives users the opportunity to enter into a new blockchain-based jurisdiction where agreements are governed by code. By entering into contracts on Ethereum Classic, you can be certain that the network remains neutral. The outcome of transactions will be dictated by code you voluntarily interact with. Unless explicitly defined by the contract code, there are no reversals, no undos, no opt-outs. Transactions are final; applications are unstoppable. Decentralized Governance There are many problems that fester due to centralization and opaqueness; corruption, unaccountability, nepotism, inefficiency and stagnation. Ultimately, centralization leads to fragility; only decentralized systems can stand the test of time. These problems can be only solved by adhering to governance systems that do not rely on a central point of failure. Just like distributed networks and the consensus protocol itself, we believe that only truly decentralized projects can survive in the long run. Ethereum Classic manifests these values by relinquishing control by a formalized central foundation. The only hierarchy is that of transparent meritocracy and mutual reputation. No backroom deals or behind-closed-doors unilateral decision making; just free and open discourse.
