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.
Groestlcoin is an ASIC-resistant cryptocurrency that boasts having “almost ZERO fees.” Although the coin itself is only pseudo-anonymous (like Bitcoin), the development team has ported a wallet (Samourai) to give you full anonymity. Groestlcoin is strictly a cryptocurrency for peer-to-peer (p2p) payments. The coin serves the same end-goal as other transactional cryptos like Bitcoin and Litecoin but accomplishes that goal with a different set of attributes. Groestlcoin accomplished a few significant “firsts” with its feature set. It was the first coin to implement Segregated Witness (SegWit) and the first to perform a Lightning Network transaction on mainnet. With the implementation of the Lightning Network, Groestlcoin has minimal fees. Transferring 10,000 GRS (~$6000 at the time of this writing) costs fractions of a fraction of a cent. Even if the GRS price rises 1000x, the transaction fee would be just a couple of pennies. Groestlcoin utilizes two rounds of Grøstl-512 for its mining algorithm. This mining algo is ASIC-resistant, for now. A developer going by the Bitcointalk username “Gruve_P” launched Groestlcoin on March 22, 2014. Since then, the team has grown to over 20 people spread all around the world. Most team members prefer to stay relatively anonymous, only sharing their first name and country of origin on the website. The team has been consistent in releasing new versions of the platform every three months. With such consistency, it shouldn’t shock you to hear all that they’ve accomplished in the last four years. The team activated SegWit in January 2017 and is currently working on Lightning Network releases for both their mobile and desktop wallets. The team and community have also built eleven different Android wallets, ten different wallets for Blackberry, and three for iOS. They’ve created more than ten desktop wallets as well. GRS has recently seen a rise in popularity, with most CPU and GPU miners moving away from networks like BTC, where ASIC miners have completely saturated the mining pool. With its robust features, focus on privacy, and innovative technology, GRS is a very lucrative choice for these miners, and has the possibility to be the next big coin that hits the market. While investing in any cryptocurrency is subject to their inherent volatile nature, the immense market potential of Groestlcoin, along with its pioneering technology and dedicated development team, make it a very strong consideration for investment.
