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.
Stakenet launched in March of 2018 by building off of a POSWallet (POSW) to Stakenet (XSN) coin swap. The Stakenet blockchain was created from the swap and is a modified blockchain based on Bitcoin. POSWallet was the original incarnation of Stakenet and offered a staking wallet that served over 100 of the most popular and common cryptocurrencies. The complete number of POSW coins in distribution grew to 250 million, so the developers burned coins from their wallet to lower the circulation to 70 million. Unfortunately, the website for the POSWallet was hacked, resulting in the team leaving the project. Instead of completely abandoning it, the developers rebuilt the blockchain from the ground up with better features and have now migrated POSW to the superior XSN. The digital coin that powers the Stakenet platform is XSN. It features completely secure Trustless Proof of Stake and is compatible with the Lightning Network, which allows for instant transactions with little to no fees associated with them. XSN will be used to pay for any services on the platform. It can interact with other coins, which will make for many amazing opportunities for investors utilizing the program. For example, by using the platform’s Cross Chain Proof of Stake, holders can stake XSN and earn Bitcoin rewards. Users will also be able to pay anyone using any cryptocurrency just by having XSN. The coin will offer incredible flexibility in the way that it interacts with other cryptocurrencies.
