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.
Enjin Coin is a cryptocurrency for virtual goods created by Enjin. Enjin is the “largest gaming community platform online” with over 250,000 gaming communities and 18.7 million registered gamers. The Enjin team is designing the coin completely around gaming with the goal of it being the most usable cryptocurrency for the industry. The project includes the Enjin Coin as well as a suite of software development kits (SDKs) that developers can integrate into their games and communities. Bringing blockchain to gaming helps to reduce the high fees and fraud that’s prevalent in the transfer of virtual goods. Enjin Coin is an ERC20 token built on the Ethereum network. With that, the project not only acts as a cryptocurrency but also has smart contract capabilities. It’s also one of the first projects testing the Raiden Network, Ethereum’s version of the Lightning Network. The Enjin Coin platform provides a laundry list of features through its public API and SDKs. To keep things brief, though, we’ll only be discussing a few of the major ones in this article. The largest value Enjin Coin brings to the gaming community is in its creation and management of virtual goods. Developers on each platform can easily create a currency unique to their community that’s backed by Enjin Coin as the parent currency. This gives the coins all the benefits of the blockchain (speed, cost, security, etc…) while still staying customized to their respective platforms. Enjin, the company behind Enjin Coin, is the largest online gaming community creation platform. Started in 2009, the company receives 60 million views per month and transacts millions of U.S. dollars each month in their community stores. The team is deploying Enjin Coin across the entire Enjin CMS platform – over 250,000 gaming websites. Advisors to the project consist of Anthony Diiorio (Ethereum co-founder) and Pat LaBine (previous producer and technical director at Bioware). Enjin has also formed partnerships with Unity, PC Gamer, and NRG eSports. The team held a successful ICO in late 2017 in which they raised ~$35 million between the private and public rounds. Although it’s still a young project, the team spent the last quarter of 2017 building the Platform API, Mobile Smart Wallet, and a Java SDK alongside creating a Minecraft plugin. They’ve got plenty in store for 2018, but the highlights include various platform plugins, the Efinity release, and numerous other SDKs. Enjin also features a tool known as TopLists, which allow users to rank games, servers, teams and any other item. TopLists will be deployed as a decentralized smart contract with functionalities that will allow for market bidding or democratic voting. List creators are incentivized to promote and market their list because these creators will receive tokens when users perform tasks such as voting on their list. Enjin Coin is an ambitious project that aims to integrate online virtual gaming with decentralized technologies. Enjin Coin project promises a lot, and it is only with the passage of time that we will able to see if it can deliver on those promises.
