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.
Particl is an open-source and decentralized privacy platform built on the blockchain specifically designed to work with any cryptocurrency. It allows decentralized applications (Dapps) of all sorts to be built within a secure, highly-scalable environment and be integrated directly into Particl’s flagship wallet: Particl Desktop Particl's mission is to foster a new decentralized, private and democratic economy supported by its platform and native currency (PART). All the fees generated by the platform are paid to the PART coin holders who are securing the network. PART is a privacy coin built from the Bitcoin Core codebase and is always updated to its latest version (currently 0.16.0). Capitalizing on the latest Bitcoin codebase not only allows the Particl platform to benefit from both Bitcoin’s stability and security, but also enables developers to leverage and easily fork any product, service and technology development from the Bitcoin developer community. Particl Cold Staking is enabled by smart-contract functionality and lets users securely delegate staking powers to “staking nodes” which contain no coin. The purpose of these “staking nodes” is to provide a dedicated resource connected to the Particl blockchain and stake on behalf of another wallet without being able to spend its coins. In other words, it allows users to stake offline coins. Particl's decentralized marketplace is built with privacy at its core and offers a low-cost, secure and scalable e-commerce experience. Designed to work with almost any coin, it uses several privacy-enhancing features such as default private transactions, encrypted data, secure messaging, IP address anonymization, metadata stripping, private listings and more. It is exclusively governed by the Particl community which also earns all the fees generated by the marketplace. Particl is designed so that users can easily use and build decentralized applications that can then be integrated directly into Particl Desktop. These applications foster the decentralized, private and trustless Particl economy and are built using native privacy smart-contracts. PART can be sent as three different privacy states, each with their own degree of privacy and cost: Public, Blind, Anonymous. Each state has a purpose within our privacy platform and also provides the user full control of the linkability and traceability of their transactions. Particl is the first coin in history to deploy these privacy protocols on a Bitcoin Core codebase. The Particl platform accepts a wide range of cryptocurrencies and provides maximum privacy at the same time. By using atomic swaps and third-party integrations, all incoming currency transactions are automatically converted into PART, Particl’s native currency. This way, you can use your favorite cryptocurrency while being protected by PART’s powerful privacy features.
