The Peercoin network activated in 2012 and is one of the first cryptocurrencies to ever be released. It is responsible for inventing proof-of-stake consensus, which makes it the first efficient and sustainable public blockchain technology. Peercoin was inspired by bitcoin, and it shares much of the source code and technical implementation of bitcoin. The Peercoin source code is distributed under the MIT/X11 software license. Unlike bitcoin, Namecoin, and Litecoin, Peercoin does not have a hard limit on the number of possible coins, but is designed to eventually attain an annual inflation rate of 1%. There is a deflationary aspect to Peercoin as the transaction fee of 0.01 PPC/kb paid to the network is destroyed. This feature, along with increased energy efficiency, aim to allow for greater long-term scalability. With the same encryption algorithm as Bitcoin (SHA-256), Peercoin is 100 times more energy efficient. Transactions in the Peercoin network are faster and cheaper. If there were not fierce competition on the cryptocurrency market, Peercoin would probably have long since become one of the most important cryptocurrencies. But in 2014 and 2015, however, there were many other interesting innovations in the cryptocurrency market that outperformed peercoin in a number of important properties. In contrast to DASH, Peercoin could not offer anonymity and the transactions in Dogecoin were even faster and cheaper than those of Peercoin. PoS technology ceased to be an advantage of peercoin and PoS continued to spread to other cryptocurrencies. The interest of the users drew it to the side of the minings on the CPUs and GPUs, then to the side of the Smart Contracts and PPC began to get a little forgotten. The Peercoin Team believes that adapting blockchains for wide scale use only through on-chain transactions will negatively affect the decentralization level and security of the network over time, therefore we choose to develop the Peercoin blockchain as a base layer settlement network with a sole focus on securing all forms of value recorded into the chain. This can be accomplished through Peercoin's philosophy of preserving and maximizing decentralization (which increases security) by developing the majority of features and technologies on top of the blockchain, rather than directly into the blockchain protocol itself. Thus the Peercoin Team focuses on developing second layer protocols and sub-networks that can interact with the base layer blockchain to adapt it for wide scale use and improve functionality such as tokens, smart contracts and high speed low cost transaction processing. In this way, Peercoin will act as a secure and censorship resistant base layer for the future blockchain connected world.
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.
