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.
The 2016 economic report “On the Value of Virtual Currencies” commissioned by the Bank of Canada, found three contributing components dictating a cryptocurrency’s exchange rate: The actual use of virtual currency to execute real payments. The decision of forward-looking investors to buy virtual currency (thereby effectively regulating its supply). The elements that jointly drive future consumer adoption and merchant acceptance of virtual currency. XAC Attention Addresses Attention Addresses are linked to AMARK consumer data and have specific rules enforced by the XAC protocol. There are two key functions of attention addresses: XAC-LOCK XAC-Lock is a feature that encourages continued consumer engagement with AMARK. The XAC sent to Attention Addresses is initially locked and becomes available after a maturation period. The XAC attention awards paid to consumers continually matures into availability as new XAC is earned from ongoing attention marketing. This process encourages engagement with AMARK as attention wallets will rarely have a zero XAC balance, giving consumers a consistent flow of value to spend within the ecosystem. XAC-BURN XAC-Burn is enforced at the protocol level. All transfers to Attention Addresses require 5% of the XAC transferred to be burned. The XAC -Burn feature is designed to align interests between merchants and consumers in the AMARK ecosystem. Anytime merchants use the AMARK platform for marketing, they are supporting the value of the XAC currency as protocol rules enforces a 5% burn. As such, merchants are effectively scaling the supply of XAC to match the demand from the ecosystem. This supply-side scaling mechanism will offset new coins introduced through block rewards and pressure the price of XAC to an equilibrium reflective of demand from the ecosystem.
