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.
Ontology is a new high-performance public blockchain project & a distributed trust collaboration platform.It provides new high-performance public blockchains that include a series of complete distributed ledgers and smart contract systems. Ontology is a blockchain framework supports public blockchain systems and is able to customize different public blockchains for different applications. It also supports collaboration amongst chain networks with its various protocol groups.They will constantly provide common modules on the underlying infrastructure for different kinds of distributed scenarios, such as those for the distributed digital identity framework, distributed data exchange protocol, and so on. Ontology was created in 2017 by a Chinese company called OnChain, which is led by founders Erik Zhang and Da HongFei. OnChain has had huge success in the cryptocurrency industry, as they were also the founders behind the NEO blockchain, which is now a multi-billion dollar project. Essentially, Ontology was created as a way for businesses of all sizes to install blockchain technology within their company, without having to completely change all of their current systems. The purpose of the Ontology framework is that it is not intended to operate as a single blockchain. Instead, the technology will allow businesses to make full use of both a private and public blockchain. Each and every data transaction is confirmed in a decentralized environment, meaning that no single person or authority can take control of the network.
