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.
Dropil offers a full investing suite including financial planning, retirement savings, and of course trading. Their primary target market is inexperienced investors who are looking for an easy way to enter into the cryptocurrency markets, but they also have something to offer the more experienced investor, cryptocurrency and otherwise. And they claim to be able to set-up investment planning for anyone, regardless of their risk tolerance or background. Of course the main selling point of Dropil is the automation of the cryptocurrency trading process. The platform requires little input from investors and claims it will deliver high profit margins and minimal risk of losses. A second part of the Dropil platform is the Arthur bot. This bot is the risk management bot, which manages investor portfolios and also provides arbitrage analysis. While it is less complex than Dex, it is still important as it will monitor up to 13 different exchanges and 10 different coins to find arbitrage opportunities for you. What is most important to note is that this can all be done without the use of an API as well as no user accounts needed. Future plans include expanding this functionality. The final aspect of the Dropil ecosystem is the DROP token, which is an ERC-20 token that was created to help ensure privacy, while also powering the internal economy of Dropil. The team chose to use the ERC20 protocol to help foster compatibility and quick exchange executions to benefit the entire community. The DROP token has a total supply of 30 billion coins, which was determined to be an optimal amount for asset management by the developers. It was also chosen with the optimal user base in mind, as well as the need for coins to be traded and achieve widespread adoption. The need to use the DROP token to access the feature of Dropil should ensure a good implementation and demand for the token. Dropil looks like an interesting project that is tackling the complexity of investing in cryptocurrencies. The idea of automated trading, investing and arbitrage is a compelling one, but it does sound familiar. Stocks, commodities and forex all have these types of automated systems, or robots, that promise guaranteed returns. I have yet to come across one that is reliable in the long term. Perhaps the artificial intelligence algorithm is advanced enough to change that. Perhaps cryptocurrency market movements are easier to analyze and predict.
