Nuls (NULS) is a Singaporean based project is trying to develop a highly adaptable blockchain that can be used for enterprise solutions. They have regularly used the phrase “Nuls is nothing, Nuls is everything”. In other words, Nuls is not traditionally defined and can be melded into anything that the community sees fit. Nuls is looking to solve the problems faced by blockchains by creating one that features modularity and sub-chain operability. The two part design of functional modules and microkernels will provide both an underlying network mechanism and compartmentalized features for the blockchain.Essentially this should provide scalability and security to the blockchain, while adhering to the programming practices of low coupling and high cohesion. And because the blockchain is designed to be modular, it becomes hot pluggable, allowing for the addition or removal of modules at any time. There are several blockchain problems inhibiting growth and development of the industry that have been identified by the Nuls team. One such issue is the cost of development. Because there is a shortage of blockchain proficient developers, those with skills can command higher salaries.This is simply demand exceeding supply and will eventually level out as more IT professionals learn blockchain skills. That’s when businesses will see greater adoption of the technology, and only the most trustworthy blockchains will be of interest. Nuls is working to make trustworthy solutions to business problems. Nuls is primarily focused on making blockchain more accessible for developers and businesses. It seeks to do this through its modularity and the use of sub-chains, and hopes to break the complexity associated with blockchain projects, while also solving the scalability issue that is hindering the growth of the industry. Nuls will make trust simpler, increasing the adoption rate of blockchain technology by businesses. They will also lower the cost of entry by removing complexity and increasing the supply of developers capable of programming blockchain applications. Taken all together, the Nuls ecosystem will benefit developers, businesses, and cryptocurrency enthusiasts by providing needed solutions and increasing usage and adoption of blockchain technology.

Dai is a stablecoin. It is an Ethereum ERC20 token that is pegged to $1 USD — every Dai is worth $1, and will always be worth $1, regardless of how much Dai is in existence. There is no centralized authority like Tether that backs its value, and no traditional bank that backs each Dai with a real US dollar. There is nothing that can be shut down, and no centralized authority that needs to be trusted. Dai lives entirely within the Ethereum blockchain using smart contracts. *Features of Dai: 1. Dai is always worth $1 USD each 2. It can be freely traded like any other ERC20 token 3. Anyone with an Ethereum wallet can own, accept, and transfer it 4. It can be exchanged without any middleman 5. No individual person or company has control over it 6. No government or authority can shut it down *How Dai Works? Dai is a masterpiece of game theory that carefully balances economic incentives in the pursuit of one goal — a token that is continuously approaching the value of $1 USD. When Dai is worth above $1, mechanisms work to decrease the price. When Dai is worth below $1, mechanisms work to increase the price. The rational actors that take part in these mechanisms do so because they earn money anytime Dai is not perfectly worth $1. This is why Dai is always floating slightly above or below $1 — it is an endless wave function bouncing infinitely close to $1, but never quite achieving it. The farther Dai goes from $1, the more incentive there is to fix it. This is the magic of Dai. *How is Dai Created? Dai is simply a loan against Ethereum. By using the MakerDAO dApp, advanced users can take loans out in Dai against their ETH holdings. First, ETH is turned into “wrapped ETH” (WETH), which is simply an ERC20 wrapping around ETH. This “tokenizes” ETH so it can be used like any other ERC20 token. Next, WETH is turned into “pooled ETH” (PETH), which means it joins a large pool of Ethereum that is the collateral for all Dai created. Once you have PETH, you can create a “collateralized debt position” (CDP), which locks up your PETH and allows you to draw Dai against your collateral, which is PETH. As you draw out Dai, the ratio of debt in the CDP increases. There is a debt limit that sets a maximum amount of Dai you can draw against your CDP. Once you have Dai, you can spend or trade it freely like any other ERC20 token. *There are several important reasons why you would create Dai, despite the hassle: 1. You need a loan, and have an asset (ETH) to use as collateral for your loan 2. You believe ETH is going up in value. You can use your CDP to buy ETH on margin — you lock up your ETH in a CDP, draw Dai against it, use the Dai to buy more ETH on an exchange, and then use that ETH to further increase the size of your CDP. This can be accomplished without any third-party or centralized authority allowing you to do so — margin trading can be accomplished entirely on the blockchain. 3. The demand for Dai has driven the price above $1 USD. When this occurs, you can create Dai then immediately sell it on an exchange for greater than $1 USD. This is essentially free money, and is one of the mechanisms the Maker system uses to keep Dai pegged to $1 USD. Dai being worth over $1 USD encourages more Dai to be created. These three reasons are enough to ensure that Dai is continually created.
