MKR is a cryptocurrency depicted as a smart contract platform and works alongside the Dai coin and aims to act as a hedge currency that provides traders with a stable alternative to the majority of coins currently available on the market. Maker offers a transparent stablecoin system that is fully inspectable on the Ethereum blockchain. Founded almost three years ago, MakerDao is lead by Rune Christensen, its CEO and founder. Maker’s MKR coin is a recent entrant to the market and is not a well known project. However, after today it will be known by many more people after blowing up 40% and it is one of the coins to rise to prominence during the recent peaks and troughs. After being developed by the MakerDAO team, Maker Dai officially went live on December 18th, 2017. Dai is a price stable coin that is suitable for payments, savings, or collateral and provides cryptocurrency traders with increased options concerning opening and closing positions. Dai lives completely on the blockchain chain with its stability unmediated by the legal system or trusted counterparties and helps facilitate trading while staying entirely in the world of cryptocurrencies. The concept of a stablecoin is fairly straight forward – it’s a token that has its price or value pegged to a particular fiat currency. A stablecoin is a token (like Bitcoin and Ethereum) that exists on a blockchain, but unlike Bitcoin or Ethereum, Dai has no volatility. MKR is an ERC-20 token on the Ethereum blockchain and can not be mined. It’s instead created/destroyed in response to DAI price fluctuations in order to keep it hovering around $1 USD. MKR is used to pay transaction fees on the Maker system, and it collateralizes the system. Holding MKR comes with voting rights within Maker’s continuous approval voting system. Bad governance devalues MKR tokens, so MKR holders are incentivized to vote for the good of the entire system. It’s a fully decentralized and democratic structure, then, which is an underutilized USP of blockchain tech. Value volatility is a relative concept among both cryptos and fiat currencies. The US dollar, for example, was worth 110.748 yen on July 9, 2018. On July 4, 2011, $1 was worth 80.64 yen, and on March 18, 1985, $1 was worth 255.65 yen. These are major differences in exchange rates, and inflation within each country makes each currency worth different values even when compared to themselves. One USD in 1913 is worth the equivalent of $25.41 today, and even $1 in 1993 is worth the equivalent of $1.74 today. Stablecoins don’t negate these basic economic principles of value. Instead, both Tether and Dai have values pegged to the U.S. dollar. This is done to stabilize the price.
Tezos is a coin created by a former Morgan Stanley analyst, Arthur Breitman. It is a smart contract platform which is does not involve in mining Tezos coins. It is a coin that promotes themselves on major ideas of self-amendment and on-chain governance. It is an Ethereum-like blockchain that hosts smart contracts. It allows the community to vote and improve its flaws. Any token holder may delegate their voting rights to others in the network. The coin uses a generic network shell which allow different transaction and consensus protocols that a blockchain needs to be compatible. The source code is implemented on OCaml which is a fast, flexible and functional programming language which should suit an ambitious project and its technical requirements. Tezos’ proof-of-stake consensus algorithm is different from the delegated proof-of-stake (dPOS) where they go by the name liquid proof-of-stake. This liquid proof-of-stake that Tezos uses focus in filling the gap between both security and decentralization but still being able to take advantage of the benefits that delegated proof-of-stake offers. The staking process in Tezos is called “baking”. In this blockchain, bakers who make deposits will be rewarded for signing up and publishing blocks. However, if a baker commits any bad behavior the deposits will be forfeited. Baking & Endorsing Baking is what Tezos refers to as the action of signing and publishing a new block in the chain. Bakers need at least 10,000 XTZ to qualify as a delegate, and having additional delegated stake increases their chances of being selected as a Baker or Endorser. At the beginning of each cycle (4096 blocks), the Bakers for each block are randomly selected and published. Bakers earn a block reward of 16 XTZ for baking a block. In addition to the Baker, 32 Endorsers are randomly selected to verify the last block that was baked. Endorsers receive 2 XTZ for each block they endorse. Block Rewards & Inflation Block rewards are funded by protocol defined inflation. Rewards are calibrated so that the number of XTZ tokens grows at roughly 5.5% per year. If 100% of Tezos tokens are delegated, the annualized yield will be 5.5%. Currently, 38% of Tezos tokens have been delegated, including the 10% owned by the Tezos Foundation, so the annualized yield is currently 14%. To ensure Bakers and Endorsers act honestly, they are required to post a security deposit for each block they Bake or Endorse. They forfeit this deposit in the event of malicious activity, such as double baking or double endorsing a block. In 2018, Tezos successfully launched their main network after delaying the launch due to corporate governance disputes. The Tezos foundation planned to transition the network to a mainnet, or a more complete version. The foundation has also raised $232 million in July 2017 to build the network and issue a new type of cryptocurrency to its backers in one of the largest- ever initial coin offerings. The founders have also made it clear in their blog that the network is using a new blockchain technology hence unexpected issues may still occur affecting the network.
