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.
BitBay is a free, decentralized marketplace for buying and selling goods and services on the blockchain. You can connect directly with peers and transact without the need for a middleman like Amazon, eBay, or Craigslist. Transactions are secure and anonymous. They’re also guaranteed by escrow. The project aims to be the new standard for eCommerce, allowing individuals to trade one-to-one at scale. As a result, BitBay claims it will revolutionize global trade. It’s seemingly a great solution for other niche applications as well, where groups of people aren’t served by existing marketplaces. In the beginning, BitBay got off to a rocky start. In 2014, the original founders raised capital in bad faith and quickly abandoned the project after fundraising, leaving the lead developer holding the bag. It seemed like BitBay was finished, but the developer continued working on the project out of a sense of duty to the original investors, without access to the capital raised in the fundraising round. The BAY token is the transactional token in the marketplace. You use it to buy and sell, and it can also participate in freezes, escrow, bets, swaps, etc. The token itself operates like Bitcoin and is secured by the network. Although you can use BAY for transactions, you don’t have to. You do, however, have to use BAY if you’d like to take part in token staking. BAY’s price cratered after the original founders left and stayed low until March 2017 when it took off. It has been through several cycles of bull and bear runs, with a max price over 30 cents in January 2018 before retreating to its current value. BitBay supports all kinds of privacy and security measures. It’s easy to create a multisignature wallet for added security. There are integrations for Tor and other proxies that help anonymize your connection to the marketplace. An on-screen keyboard allows for password or key entry without using your keyboard and being susceptible to keylogging. Additionally, you can create images with your private key embedded, so that finding a stored key is more difficult for a hacker. The marketplace also has functionality for time locking contracts and swapping currencies. This enables all kinds of cross-chain transactions and financial implements. The time lock and other smart contract elements make it possible to create bets, escrow, futures and options trades, or any number of other financial transactions. The idea and implementation by BitBay, of a decentralized marketplace and trading platform is brilliant and shows further promise of expansion.The rocky beginning of the cryptocurrency and its subsequent comeback as a promising platform indicate that the developers are in it for the long haul and don’t plan on abandoning the platform after all these years.
