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.
'WAX is a purpose-built blockchain and protocol token designed to make e-commerce transactions faster, easier, and safer for all participants. The WAX Blockchain uses Delegated Proof of Stake (DPoS) as its consensus mechanism and is fully backward compatible with EOS. The custom features and incentive mechanisms developed by WAX are designed to optimize the blockchain's usability in e-commerce, and encourage voting on guilds and proposals. WAX has created a suite of blockchain-based tools upon which dApps, marketplaces, and native non-fungible tokens (NFTs) are built. These tools include services to support e-commerce operations such as the WAX Cloud Wallet, SSO and OAUTH, a native RNG service, and a developer portal. The resulting technology reportedly represents a blockchain architecture with 500 millisecond block times, is fee-less for customers, and leverages voting rewards to incentivize participation in the selection of block producers and proposals' '
