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.
Bancor is a blockchain protocol that allows users to convert between different tokens directly as opposed to exchanging them on cryptocurrency markets. The project offers a network, which we’ll discuss soon, that works to bring liquidity to the majority of tokens that lack a consistent supply/demand in exchanges. That network is built on smart contracts and a new class of cryptocurrencies that the team calls “Smart Tokens.” Bancor is looking to provide support to the illiquidity that currently exists within the cryptocurrency market. Illiquidity isn’t so much an issue for top coins like Bitcoin or Ethereum because there are always buyers and sellers looking to exchange those coins. It is definitely an issue, however, for the thousands of other tokens that may serve legitimate decentralized purposes but haven’t attracted enough attention in the market to be liquid. Bancor’s protocol uses smart contracts to create Smart Tokens, which serve as an alternative mechanism for trading. A key characteristic of the protocol is that it doesn’t call for an exchange of tokens with a second party, as in the case of cryptocurrency exchanges. Rather, it employs Smart Tokens to convert between different ERC-20 tokens internally. These conversions take place through the blockchain’s protocol and completely outside of cryptocurrency exchanges. Smart Tokens process token conversions internally by holding reserves of other ERC20 tokens within their Smart Contract. They can then convert back and forth between those reserves as users request it. The Bancor team consists of a core Foundation Council and their Advisory Board. The Foundation Council includes four individuals based out of Zug, Switzerland. Bernard Lietaer is a Belgian civil engineer, economist, author, and professor. Lietaer specialized in monetary systems and promotes the notion of communities creating their own local currencies. Guy Benartzi serves as co-founder and is recognized for founding the gaming company, Mytopia. Benartzi also co-founded Particle Code, a development studio based in Tel Aviv, Israel. Guido Schmitz-Krummacher is an executive of the Bancor Protocol foundation that’s involved with a variety of commercial entrepreneurial ventures in Switzerland. His involvement in the crypto space includes that of Bancor as well as an executive position in crowdfunding network, Tezos (XTZ). One of the key elements of the Bancor Network is the automated pricing. This comes from the Smart Tokens’ built-in automated market makers. These automated market makers mean that the tokens’ smart contracts always buy or sell Smart Tokens from or to any user in exchange for any connector token (as well as any token found in the network). The price comes from the Bancor Formula. This formula that is responsible for balancing a Smart Token’s demand and supply while also maintaining the ratio between the token’s total value with the connector token balances. The creator of the Smart Token configures these ratios, known as the connector weight. The creator can adjust them with the goal of decreasing or increasing the liquidity level of the token. The connector weight indicates price sensitivity, or how much sells and buys affect the price movement. Any time the prices no longer syncs with prices listed on external exchanges, the arbitrageurs will quickly balance the gaps.'
