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.
Verge coin started its cryptocurrency journey in 2014, going by the name of DogecoinDark. The reason it was created was to create a truly private cryptocurrency. The founder of Verge felt that Bitcoin wasn’t anonymous, so he decided to build a new blockchain where transactions could not be traced. Verge uses multiple anonymity-centric networks such as TOR and I2P. The IP addresses of the users are fully obfuscated. The Core QT wallet has built-in TOR integration as well as SSL encryption which adds an extra level of security. Verge is an open source project with an active team of developers from all over the world. The development team is always in close contact with the community. Verge is not a private company funded through an ICO or premining. Wraith Protocol is a technology upgrade package that enables our users to be able to send and receive payments privately across our blockchain by enabling stealth addressing services. Additionally this update removes our QT wallet users off of clearnet and migrates everyone to SSL enabled Tor. Verge focuses on security and maintaining user anonymity just like Monero; so that is its latent upside. Many investors are also applauding its unique technology. Having been improved and integrated with the Wraith Protocol technology, verge users are now able to effortlessly switch between private and public ledgers on the Verge blockchain. Before this, private and public ledgers were mutually selected, meaning that they could not co-exist on a very similar blockchain. But investors are today free to use whatever ledger they want. A good example was when Wraith Protocol switched ON – one will not be able to view the transaction data, not even via the blockchain explorer. Additionally, Verge makes obscure the IP addresses in both instances. When coupled with Wraith Protocol Verge certainly becomes the only undetectable cryptocurrency. Furthermore, transaction speed on Verge is light speed at 5 seconds only, using Simple Payment Verification technology. Verge also maintains a community feel since it’s not a private company. Community members are responsible for the direction of its technology and where the coin heads next. It currently offers a number of secure mobile wallets, including the Tor Android Wallet, which offers mobile anonymity, another big plus over Bitcoin. Verges offers five different Proof-of-Work algorithms for mining. They include; Lyra2rev2, Scrypt, X17, blake2s and myr-groestl. Offering a choice of five different algorithms promotes inclusion, since a wider variety of users will now have an opportunity to not only mine but influence the network. Should one algorithm demand greater mining resources, users get an option of just switching to a different one.
