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.
Decentraland is an Ethereum-powered virtual reality platform. In this virtual world, you purchase plots of land that you can later traverse, build upon, and monetize. There’s no limit to what you can do. It’s the first digital platform that’s completely owned by its users. Similar to games like Skyrim and Fallout, Decentraland is an all-immersive virtual universe. However, instead of playing on a 2-dimensional screen, you participate in a 3-dimensional world. It seems to be the logical next step before creating full-blown AI-based games in the physical space à la Westworld. Similar groupings on LAND comprise Districts. Districts are basically communities that revolve around a shared theme. For example, there may be a District just for crypto enthusiasts with cryptocurrency apps and services. The Decentraland team is led by Ari Meilich (Project Lead) and Esteban Ordano (Tech Lead). Ordano previously worked at Bitpay as a software engineer and founded Smart Contract Solutions, Inc. Both founders have also worked together in creating Stremium and Bitcore. Decentraland has been around for longer than you may think. The team hit their first development milestone, Stone Age, in June 2015. This was a simple, pixelated grid that allocated pixels to users through a proof-of-work algorithm. Most recently, they held a Terraform Event in which they sold LAND in the new, 3D world. The team has also partnered with district0x, Aragon, and imToken to provide some of their services. MANA is the token used to buy lands in Decentraland. The Blockchain platform can be incorporated in order to buy or sell the various digital assets available in the virtual world. An unclaimed land would have the same market pricing on every exchange possible and precisely the developers are on a hunt for such since as they can build on top of it, and attract lot of popularity. However, one must keep in mind that the land parcels are different from them and each one of them varies according to the various market conditions of that time. Mana can be a great investment and can be bought by trading and with other Bitcoin, Ethereum, or any other prominent cryptocurrency and on some of the most notable cryptocurrency exchanges. Specifically, Binance and Huobi are two of the best cryptocurrency exchanges that one can suggest for trading Mana tokens. The Decentraland coin isn’t a minable cryptocurrency as it is issued on the Ethereum blockchain, unlike Bitcoin and other similar currencies. So users looking to engage in some Decentraland mining will be disappointed. Instead, it was sold during token sales and is now being traded on exchanges.
